TWO:The most perfect castings for gear wheels and pulleys and other pieces which can be so moulded, are made by drawing the patterns through templates without rapping. These templates are simply plates of metal perforated so that the pattern can be forced through them by screws or levers, leaving the sand intact. Such templates are expensive to begin with, because of the accurate fitting that is required, especially around the teeth of wheels, and the mechanism that is required in drawing the patterns, but when a large number of pieces are to be made from one pattern, such as gear wheels and pulleys, the saving of labour will soon pay for the templates and machinery required, to say nothing of the saving of metal, which often amounts to ten per cent., and the increased value of the castings because of their accuracy.The religious tendency of Seneca��s philosophy appears rather in his psychology than in his metaphysics, in the stress which he lays on human immortality rather than in his discussions on creation and divine providence. His statements on this subject are not, indeed, very consistent, death being sometimes spoken of as the end of consciousness, and at other times, as the beginning of a new life, the ��birthday of eternity,�� to quote a phrase afterwards adopted by Christian preachers. Nor can we be absolutely certain that the promised eternity is not merely another way of expressing the soul��s absorption into and identification with the fiery element whence it was originally derived. This, however, is an ambiguity to be met with in other doctrines of a spiritual existence after death, nor is it entirely absent from the language even of Christian theologians. What deserves attention is that, whether the future life spoken of by Seneca be taken in a literal or in a figurative sense, it is equally intended to lead our thoughts away from the world of sensible experience to a more ideal order of things; and, to that extent, it falls in with the more general religious movement of the age. Whether Zeller is, for that reason, justified in speaking of him as a Platonising Stoic seems more questionable; for the Stoics always agreed with Plato in holding that the soul is distinct from and superior to the body, and that it is consubstantial with the animating principle of Nature. The same circumstances which were elsewhere leading to a revival of Platonism, equally tended to develope this side of Stoicism, but it seems needless to seek for a closer connexion between the two phenomena.376

A hydrocyclone (liquid cyclone) injects treatment solution into stationary equipment to perform separation, classification, and concentration, and is an innovative separator with a very simple structure and no drive unit.

Structure of a hydrocyclone (liquid cyclone)

A suspension containing fine particles of several micrometers or more is supplied to a cylindrical container circumferentially at high speed. And as a result it starts to rotate and a centrifugal force is generated. At this time a gravitational acceleration of several tens of thousands of G is generated in the circumferential direction, and thus leading to fast sedimentation and concentration of the fine particles. The separated concentration can be freely selected by changing the supply rate (supply pressure and flow rate) and the flow ratio of the outlet. Our hydrocyclone (liquid cyclone) was designed and manufactured to classify and concentrate fine particles, and so has a small element.

THREE:In the world of thought no less than in the world of action, the boundless license which characterised the last days of Roman republicanism was followed by a period of tranquillity and restraint. Augustus endeavoured to associate his system of imperialism with a revival of religious authority. By his orders a great number of ruinous temples were restored, and the old ceremonies were celebrated once more with all their former pomp. His efforts in this direction were ably seconded by the greatest poet and the greatest historian of the age. Both Virgil and Livy were animated by a warm religious feeling, associated, at least in the case of the latter, with a credulity which knew no bounds. With both, religion took an antiquarian form. They were convinced that Rome had grown great through faith in the gods, that she had a divine mandate to conquer the world, and that this supernatural mission might be most clearly perceived in the circumstances of her first origin.307 It is also characteristic that both should have been provincials, educated in the traditions of a201 reverent conservatism, and sympathising chiefly with those elements in the constitution of Rome which brought her nearest to primitive Italian habits and ideas. Now it was not merely the policy, it was the inevitable consequence of imperialism to favour the provinces308 at the expense of the capital, by depriving the urban population and the senatorial aristocracy of the political preponderance which they had formerly enjoyed. Here, as in most other instances, what we call a reaction did not mean a change in the opinions or sentiments of any particular persons or classes, but the advent of a new class whose ways of thinking now determined the general tone of the public mind.There is a story that Plato used to thank the gods, in what some might consider a rather Pharisaic spirit, for having made him a human being instead of a brute, a man instead of a woman, and a Greek instead of a barbarian; but more than179 anything else for having permitted him to be born in the time of Socrates. It will be observed that all these blessings tended in one direction, the complete supremacy in his character of reason over impulse and sense. To assert, extend, and organise that supremacy was the object of his whole life. Such, indeed, had been the object of all his predecessors, and such, stated generally, has been always and everywhere the object of philosophy; but none had pursued it so consciously before, and none has proclaimed it so enthusiastically since then. Now, although Plato could not have done this without a far wider range of knowledge and experience than Socrates had possessed, it was only by virtue of the Socratic method that his other gifts and acquisitions could be turned to complete account; while, conversely, it was only when brought to bear upon these new materials that the full power of the method itself could be revealed. To be continually asking and answering questions; to elicit information from everybody on every subject worth knowing; and to elaborate the resulting mass of intellectual material into the most convenient form for practical application or for further transmission, was the secret of true wisdom with the sage of the market-place and the workshop. But the process of dialectic investigation as an end in itself, the intense personal interest of conversation with living men and women of all classes, the impatience for immediate and visible results, had gradually induced Socrates to restrict within far too narrow limits the sources whence his ideas were derived and the purposes to which they were applied. And the dialectic method itself could not but be checked in its internal development by this want of breadth and variety in the topics submitted to its grasp. Therefore the death of Socrates, however lamentable in its occasion, was an unmixed benefit to the cause for which he laboured, by arresting (as we must suppose it to have arrested) the popular and indiscriminate employment of his cross-examining method,180 liberating his ablest disciple from the ascendency of a revered master, and inducing him to reconsider the whole question of human knowledge and action from a remoter point of view. For, be it observed that Plato did not begin where Socrates had left off; he went back to the germinal point of the whole system, and proceeded to reconstruct it on new lines of his own. The loss of those whom we love habitually leads our thoughts back to the time of our first acquaintance with them, or, if these are ascertainable, to the circumstances of their early life. In this manner Plato seems to have been at first occupied exclusively with the starting-point of his friend��s philosophy, and we know, from the narrative given in the Apologia, under what form he came to conceive it. We have attempted to show that the account alluded to cannot be entirely historical. Nevertheless it seems sufficiently clear that Socrates began with a conviction of his own ignorance, and that his efforts to improve others were prefaced by the extraction of a similar confession of ignorance on their part. It is also certain that through life he regarded the causes of physical phenomena as placed beyond the reach of human reason and reserved by the gods for their own exclusive cognisance, pointing, by way of proof, to the notorious differences of opinion prevalent among those who had meddled with such matters. Thus, his scepticism worked in two directions, but on the one side it was only provisional and on the other it was only partial. Plato began by combining the two. He maintained that human nescience is universal and necessary; that the gods had reserved all knowledge for themselves; and that the only wisdom left for men is a consciousness of their absolute ignorance. The Socratic starting-point gave the centre of his agnostic circle; the Socratic theology gave the distance at which it was described. Here we have to note two things��first, the breadth of generalisation which distinguishes the disciple from the master; and, secondly, the symptoms of a strong181 religious reaction against Greek humanism. Even before the end of the Peloponnesian War, evidence of this reaction had appeared, and the Bacchae of Euripides bears striking testimony to its gloomy and fanatical character. The last agony of Athens, the collapse of her power, and the subsequent period of oligarchic terrorism, must have given a stimulus to superstition like that which quite recently afflicted France with an epidemic of apparitions and pilgrimages almost too childish for belief. Plato followed the general movement, although on a much higher plane. While looking down with undisguised contempt on the immoral idolatry of his countrymen, he was equally opposed to the irreligion of the New Learning, and, had an opportunity been given him, he would, like the Reformers of the sixteenth century, have put down both with impartial severity. Nor was this the only analogy between his position and that of a Luther or a Calvin. Like them, and indeed like all great religious teachers, he exalted the Creator by enlarging on the nothingness of the creature; just as Christianity exhibits the holiness of God in contrast and correlation with the sinfulness of unregenerate hearts; just as to Pindar man��s life seemed but the fleeting shadow in a dream when compared with the beauty and strength and immortality of the Olympian divinities; so also did Plato deepen the gloom of human ignorance that he might bring out in dazzling relief the fulness of that knowledge which he had been taught to prize as a supreme ideal, but which, for that very reason, seemed proper to the highest existences alone. And we shall presently see how Plato also discovered a principle in man by virtue of which he could claim kindred with the supernatural, and elaborated a scheme of intellectual mediation by which the fallen spirit could be regenerated and made a partaker in the kingdom of speculative truth.
