Title: Improvements relating to machines for grinding crankshafts and the like
IPC: B24B5/42
Filed: 1936-03-03
Abstract: 450,300. Grinding crankshafts &c. CHURCHILL MACHINE TOOL CO., Ltd., and JONES, J. C., Atlantic Street, Broadheath, Manchester. March 3, 1936, No. 6403. [Class 60] [See also Group XXXVII] In a crankshaft or like grinding-machine, electrically operated means is provided for bringing the work spindle to rest in a desired position, comprising a slip ring d on the spindle with a continuous part engaged by a brush f and a cut-away and insulated part e, whereby the circuit through a brush g making contact with the ring is broken, thereby stopping the motor. When grinding is complete, a " stop " push button m is operated, which causes a quick reduction of speed of the work spindle, which is then stopped by the arrival of the sector e at the brush g, a brake also being applied to bring the driving motor a quickly to rest. The motor a receives current from a variable voltage generator h and an exciter i, and is started by operating the push-button switch k, which energizes a contactor coil q<2> to close the contactor q and open an interlock contact q<1>, thereby de-energizing the coil n<2> of contactor n and closing interlock n<1> and the coil p<2> of contactor p. A relay r<2> also is closed, the contact s thereof shorting a slowing down resistance t in the generator field circuit, and the contact u maintaining the " start pushbutton circuit ; a resistance v prevents deenergization of the coil r<2> by the slip ring when both brushes f, g are on the metal of the ring. When grinding is complete, push-button m is opened, de-energizing the relay r<2> to open contacts s, u and inserting the resistance t to slow down the motor, regenerative braking causing quick reduction of speed. When the brush g comes on the sector e, the circuit of coil q<2> is opened, the circuit of contactor n being closed to brake the motor dynamically, and the main contactor p also being opened. The work spindle may be inched by means of a relay x closed by a push-button w, the contact w<1> of the relay closing, and contact w<2> opening. The slip ring is thus put out of action and the motor may be turned at slow speed by closing the push-button w. The slip ring may be on the periphery instead of on the face of the disc carrying it, and it is rotatably adjustable, an indicator being fitted to show the position of the sector e.

Title: Electrophotographic material
IPC: G03G5/14
Filed: 1966-02-15
Abstract: 1,116,004. Electrophotography. EASTMAN KODAK CO. 15 Feb., 1966 [15 Feb., 1965], No. 6597/66. Heading H1K. An electrophotographic material is made by coating a support with an electrically conductive organic resin solution, drying the layer and thereafter applying a solution containing an organic photo-conductor, a polymeric binder and a polyurethane resin containing reactive isocyanate radicals. A modification of the method comprises coating with an adhesionpromoting subbing layer before applying the conductive solution e.g. an organic solution containing methacrylic acid/methyl acrylate copolymer. The substrate, which is preferably transparent, may be cellulose acetate, cellulose triacetate, polyethylene terephthalate, polystyrene, polymethyl methacrylate, or polycarbonate. The polyurethane may be present in the photo-conductive solution in an amount 0À1 to 1.0 wt. per cent and may contain 1 to 15% unreacted isocyanate groups, e.g. the product of poly (oxypropylene) diol and tolylene di-isocyanate. The photo-conductor may be triphenylamine, anthracene, acenaphthene, bis (4 - diethylamino - 2 - methylphenyl) - phenyl methane, p-diphenylbenzene, benzanthrone, 1, 5-dicyanonaphthalene, 1,4 dicyanonapthalene, aminophthalodinitrile and nitrophthalodinitrile. The polymeric binder may be a polystyrene, polyethylene terephthalate, polycarbonate or acrylic resin. The electrically conductive organic resin solution may be Cu 2 I a  and poly (vinyl formal) in acetonitrile or a water-soluble salt of a resinous carboxy esterlactone in methylene and propylene chlorides e.g. the sodium salt of a carboxybutyl ester lactone of maleic anhydride and vinyl acetate copolymer. Many other starting materials for the preparation of the lactones are exemplified. The use of polyurethane in the photo-conductive composition is said to give better adhesive properties between the various layers due to cross-linking. 4-(4-n-amyloxyphenyl)-2, 6-bis (4-ethylphenyl) thiapyrylium perchlorate may be added to the composition.

Title: Improvements in or relating to cartridge magazines for automatic firearms
IPC: F41A9/70
Filed: 1946-03-05
Abstract: 609,053. Cartridge magazines. BREVETS AERO-MECANIQUES SOC. ANON. March 5, 1946, No. 6758. Convention date, Sept. 29, 1945. [Class 92 (ii)] Relates to cartridge magazines for automatic firearms having a portion near the outlet of variable capacity to take up the sudden movement as each cartridge leaves the magazine and allow a substantially continuous movement of the remaining cartridges. According to the invention, a cartridge magazine is provided in which the portion of variable capacity is of variable cross-section. A box-type magazine body 11 ends in a mouth 13 adapted for cooperation with the breech-block 15 of a firearm. Near the mouth 13, the magazine has an enlarged portion 16, the walls 17 of which are apertured for the passage of levers 18 pivoted at 19 and acted on by springs 20. A follower 21 acted on by a spring 22 urges the cartridges 12 towards the outlet 13 and in so doing tends to urge apart the levers 18 against the action of springs 20. Stops 24 limit the outward movement of said levers. As the leading cartridge 23 is fed into the firearm the levers 18 move together and so urge the foremost cartridges towards the breech, the follower 21 meanwhile sets all the cartridges in motion and so forces the levers 18 apart again. Modifications are described in one of which the portion of the magazine having variable capacity is of arcuate form. It is also stated that instead of using levers 18, the walls of the portion 16 may be of flexible material acted on by resilient means. In an arcuate form, the inner and outer walls may change in radius and length.
