FORE:It is not intended to claim that this platen-reversing motion cannot, like any other mechanical movement, be resolved mathematically, but that the mechanical conditions are so obscure and the invention made at a time that warrants the supposition of accidental discovery.But neither when he left the darkling womb,
FORE:Lawrence proceeded to unpack his parcel. Inside were two cases which he opened and exposed in the light of the flaming gas.
FORE:The Countess was at home, and glad to see her visitor. The back drawing-room was cool and secluded and opened on to the garden. Leona Lalage lounged back in a deep chair and indicated the cigarettes on a table.
FORE:Although a system but recently developed, the employment of hydraulic machinery for transmitting and applying power has reached an extended application to a variety of purposes, and gives promise of a still more extensive use in future. Considered as a means of transmitting regularly a constant amount [54] of power, water apparatus is more expensive and inferior in many respects to belts or shafts, and its use must be traced to some special principle involved which adapts hydraulic apparatus to the performance of certain duties. This principle will be found to consist in storing up power in such a manner that it may be used with great force at intervals; and secondly, in the facilities afforded for multiplying force by such simple mechanism as pumps. An engine of ten-horse-power, connected with machinery by hydraulic apparatus, may provide for a force equal to one hundred horse-power for one-tenth part of the time, the power being stored up by accumulators in the interval; or in other words, the motive power acting continuously can be accumulated and applied at intervals as it may be required for raising weights, operating punches, compressive forging, or other work of an intermittent character. Hydraulic machinery employed for such purposes is more simple and inexpensive than gearing and shafts, especially in the application of a great force acting for a considerable distance, and where a cylinder and piston represent a degree of strength which could not be attained with twice the amount of detail, if gearing, screws, levers, or other devices were employed instead.(1.) In comparing steam-hammers with trip or crank hammers what mechanism does steam supplant or represent?(2.) What can be called the chief distinction between steam and other hammers?(3.) Under what circumstances is an automatic valve motion desirable?(4.) Why is a dead or uncushioned blow most effective?(5.) Will a hammer operate with air the same as with steam?

FORE:Youve twisted things that happened to fit what you wanted to believe, argued Larry.
FORE:"I only want one," Lawrence explained, "and this one will do admirably. I am going to take it away, if you don't mind. You will be able to recognise it by this queer yellow stain. Why didn't you decline to take them last night?"
FORE:Whether Spinoza ever read Plato is doubtful. One hardly sees why he should have neglected a writer whose works were easily accessible, and at that time very popular with thinking minds. But whether he was acquainted with the Dialogues at first hand or not, Plato will help us to understand Spinoza, for it was through the door of geometry that he entered philosophy, and under the guidance of one who was saturated with the Platonic spirit; so far as Christianity influenced him, it was through elements derived from Plato; and his metaphysical method was one which, more than any other, would have been welcomed with delight by the author of the Meno and the Republic, as an attempt to realise his own dialectical ideal. For Spinozism is, on the face of it, an application of geometrical reasoning to philosophy, and especially to ethics. It is also an attempt to prove transcendentally what geometricians only assumethe necessity of space. Now, Plato looked on geometrical demonstration as the great type of certainty, the scientific completion of what Socrates had begun by his interrogative method, the one means of carrying irrefragable conviction into every department of knowledge, and more particularly into the study of our highest good. On the other hand, he saw that geometricians assume what itself requires to be demonstrated; and he confidently expected that the deficiency would be supplied by his own projected method of transcendent dialectics. Such at least seems to be the drift of the following passage:"'Later.--The murdered man is described as being of misshapen appearance, a nose very much hooked on one side, and long hands, covered with orange-coloured warts----'"
