Title: Apparatus for sharpening blades of mechanical razors
IPC: B24D15/08
Filed: 1922-09-18
Abstract: 186,073. Rauser, E. H. P. Sept. 19, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Stropping-apparatus.-The razor blade is held by a member rotatably mounted in a frame, which is slidable between limiting-members D, Figs. 1 and 4, in a shell adapted to be held by one hand, and the sharpening is effected by axial reciprocation of a hone, shown in Fig. 2. Movement of the hone carries the frame against one of the stops D, which are so spaced that, through the engagement of adjustable levers O, Figs. 4 and 10, which are carried by the blade-supporting members, with slots P in the shell, the blade is tilted to bring its edge into engagement at the correct angle with the hone; further movement of the hone sharpens the blade. At the end of each complete reciprocation of the hone, the blade is turned through 180‹ by the engagement of a pinion F, carried by the blade-supporting members, with a rack N on the hone. The pinion is brought into engagement with the rack by axial movement of the blade-support, against the action of a spring L, by the engagement with a cam-surface H, Fig. 3, on the hone of a member E carried by the blade-support.

[Class 100 (iv)] Platen-rotation for blanking; sheet feeding and guiding arrangements.-A mechanism for aligning sheets on a type-writer platen comprises a pair of spaced radial stop-fingers arranged to engage the surface of the platen on a line parallel with the axis and located in the path of the entering edge of a sheet before it is effectively engaged by the platen, so that the sheet may be freely placed on the stop-fingers to align it with the axis of the platen, a clamping-roller arranged to engage and clamp the sheet against the platen above the line of the stop-fingers, and means for retracting the stop-fingers, to release the sheet, and bringing the clamping-roller into engagement to feed the sheet as the platen is rotated. The platen 11, Figs. 2 and 5, is driven by a ratchet 15, and a pawl 16 carried by a pulley 14 driven from pulleys 18, 22. The pulley 22 is clutched to a shaft 23 by a cone-clutch 24 operable by a lever 25. The clutch is normally opened by a spring but may be closed by a hand-lever 29 and is then held closed by a latch 32 engaging over a pin on the lever 25. The latch may be released by either of two cleats 33, 34, adjustably mounted on the pulley 22. A pair of stopfingers 52, Fig. 5, carrying stop-studs 53 are carried by a sleeve 50 on an axle 41, which also carries two arms 46 on which are mounted clamping-rollers 47. The fingers 52 and arms 46 are biassed awav from and towards the platen respectively by springs and are forced in the opposite direction by a cam 57, operable by an arm 59. A roller 61 on the arm 59 works on a cam 63 carried by the pulley 18 and provided with an adjustable portion 62. The sheet is placed on the studs 53 and the lever 29 is operated to close the clutch 24. As the roller 61 encounters the rise on the cam 62, the studs 53 are retracted and the rollers 47 engaged so that the sheet is fed until the first cleat 33 opens the clutch 24 and leaves the sheet in a position to start typing. The sheet is line-spaced by the ordinary means, the wheels 18, 22 remaining motionless with the roller 61 on the rise of the cam 62. When the sheet has been removed the lever 29 is again operated, the studs 53 return to engage the platen, and the cleat 34 then opens the clutch in readiness for the next operation. Alternatively the cam 57 is mounted on one member of a toggle, the other member of which carries a spring engaging a support, and a finger-lever is connected to the knee of the toggle.

Title: Improvements in or relating to the preparation of uranium monocarbide powder
Inventor: BLUM PIERRE
IPC: C01B31/30
Filed: 1960-07-27
Abstract: Uranium monocarbide powder is prepared by carburizing uranium powder by heating it with a gaseous hydrocarbon at a temperature below 950 DEG  C. until the carburized powder contains a proportion by weight of total carbon corresponding to uranium monocarbide, and then continuing to heat the carburized material at a temperature below 950 DEG  C. in the absence of the hydrocarbon to effect diffusion of the carbon into the uranium producing substantially pure uranium monocarbide.  The gaseous hydrocarbon may be aliphatic, e.g. methane, ethane, propane, butane, pentane, and hexane, and the proportion of the hydrocarbon used may be at least 10 times the stoichiometric proportion corresponding to the uranium monocarbide.  The uranium powder used may have a particle size of 1-100 microns, and is preferably stirred throughout in such a manner that each grain of powder comes into contact with the gaseous hydrocarbon, e.g. by carrying out the process in a receptacle which undergoes oscillatory motion.  The carburization may be carried out for a period of 1-2 hours, and the subsequent heating for a period of 3-5 hours, the preferred temperature range being 700-900 DEG  C. in both cases.  In the latter period the powder may be maintained under vacuum or in an atmosphere of inert gas, e.g. argon.  The powder may also be heated in an inert gas atmosphere or in vacuo before being treated with the hydrocarbon, and cooling at the end of the process may also be carried out under an inert gas atmosphere or in vacuo.
