Title: Device for feeding round bars, tubes and like work into machine tools
IPC: B23Q7/10
Filed: 1957-05-29
Abstract: 814,697. Grinding. SCHUMAG SCHUMACHER METALLWERKE G.m.b.H. May 29, 1957 [May 30, 1956], No. 17102/57. Class 60. [Also in Group XXX] A device for feeding round bars or tubes axially and one at a time into a grinding or polishing machine, particularly a centreless grinder, has means for receiving a bundle of bars 6 and periodically dropping the lowermost bar for engagement by feed means comprising oppositely-facing feed discs 20, 21 which are relatively staggered so that only their edges overlap and rotated in the same direction so that a bar is fed forwardly while it is supported by a rail 22 disposed below the centres of the discs. The bars are placed as a bundle with one end against a stop 29 in a trough 28 and the other end on a lever 1 which is pivoted on a fulcrum 2 and has a forked and slotted end disposed above a slotted shoot S formed between two stationary members 3, 4, one of which can be adjusted by a screw 12 for different diameters of bars. As the lever is oscillated by the periodic energisations of a solenoid 14 acting against a return spring 15, a projection 18 on the lever and a vertically-adjustable projection 7, which is movable about a pivot 9 against the action of a spring 11 by a pin 9a secured to the lever, move to permit the lowermost bar in the trough 28 to drop onto the rail 22 and between the discs 20, 21. The weight of this bar holds a contact 17 open until the bar is fed sufficiently far into the machine to let the contact close and operate an electrical time switch 23 which allows for the bar to pass between the feed discs before the solenoid 14 again is operated to move the lever and release the next bar. The height of the rail 22 and the distance between the discs 20, 21 can be adjusted to control the rate of feed and rotation of the bar. In the arrangement shown in Fig. 2, the bars are fed from the discs 20, 21 between a pair of grinding wheels 24, 25 and between discs 26, 27 which are similar to the discs 20, 21 but which also act to polish the bar after the latter has been ground.

Title: Novel polymers and their preparation
IPC: C09D163/10
Filed: 1966-04-20
Abstract: Photopolymerizable (cross-linkable) polymers are prepared by reacting a polymer comprising 10 to 100% by weight of glycidyl acrylate or methacrylate units, in an inert organic solvent solution, with a sufficient amount of acrylic acid to esterify all the glycidyl groups, in the presence of a tertiary amine catalyst and an addition polymerization inhibitor.  In the original polymer the glycidyl acrylate and/or methacrylate may be copolymerized with one or more of acrylic acid, alkyl and hydroxyalkyl acrylates or a -(hydrocarbyl)-acrylates, acrylonitrile and its a -(hydrocarbyl)-derivatives, vinyl esters of C2-C5 fatty acids and N-vinyl pyrrolidones; such polymers being obtained, for example, by solution polymerization with azodiisobutyronitrile or a peroxide catalyst.  The organic solvent may be methylene chloride, carbon tetrachloride, dichloroethane, trichloroethylene, benzene or methyl ethyl ketone. Specified as amine catalysts are N,N-diethylcyclohexylamine, triethylamine and triethanolamine; and as polymerization inhibitor, copper metal, cuprous and cupric compounds, phenyl-a -naphthylamine, methylene-bis(ethyl-t.-butyl-phenol) and N,N1 - di - 2 - naphthyl - p - phenylenediamine. The product obtained may be purified by means of a basic ion-exchange resin. The modified polymer product can be coated on a suitable support to form a photoresist, from a solution of the polymer in an organic solvent which may also contain a photoinitiator, plasticizer, inert polymeric filler (e.g. methyl methacrylate/hydroxyethyl methacrylate copolymer) and/or antioxidant.  Suitable photoinitiators include anthraquinone and naphthaquinone compounds, photoreducible dyes, and phenazine, oxazine and quinone dyes.  The plasticizer may be triethylene glycol diacetate or dipropionate, dibenzyl sebacate, diphenyl phosphate or dibutyl phthalate.
