Title: A device for controlling the needle cylinder in a circular knitting machine
IPC: D04B15/99
Filed: 1967-01-16
Abstract: 1,126,285. Knitting-machines. ELITEX ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI. 16 Jan., 1967 [14 Jan., 1966], No. 2158/67. Heading D1C. To achieve a faster build up of speed during reciprocating knitting without exceeding the critical speed of rotation of the needle cylinder the drive from a constant speed electric motor 1 to the reciprocating gear drive and clutch mechanism is through an induction clutch 2 which is under controlled slippage depending on the speed of the needle cylinder in either direction of reciprocation. Initially when rotating the cylinder in one direction or the other from rest there is no slippage but as the speed of the cylinder increases a tacko generator 21 driven from the needle cylinder produces a current voltage which is supplied to a regulater 24 which proceeds to supply a reduced power voltage to the induction clutch 2. Slippage thereby occurs until the maximum cylinder speed is achieved whereafter the reduction in speed of the cylinder causes the supply to the induction clutch to be restored and the drive to the mechanism to again occur without slippage.
Patent GB-1007012-A (GB)
Title: Oxidation of polycyclic hydrocarbons
Inventor: COPELAND PHILIP GROVES
IPC: C07C51/34
Filed: 1961-01-19
Abstract: A method of producing an oxidation product of a polycyclic hydrocarbon by causing ozone to react with the polycyclic hydrocarbon and decomposing the ozonide so formed in which the ozonide is decomposed by treatment with aqueous pyridine.  The resulting oxidation product is treated with potassium permanganate in high concentration to give the corresponding carboxylic acid.  Preferably the permanganate is added in powder form and the treatment conducted at 60-65 DEG  C.  Specified cyclic hydrocarbons are phenanthrene, fluoranthrene, pyrene, benzanthracene, chrysene, picene, benzochrysene, dibenze phenanthrene and triphenylene.  In an example a finely-dispersed stream of an ozone-oxygen mixture containing 10-15% by volume of ozone is passed through a solution of phenanthrene in chloroform at - 20 DEG  C. until the amount of ozone absorbed is equivalent to one mol. per mol. of phenanthrene.  The crude ozonide is then precipitated by the addition of light petroleum and is dissolved in equal parts of water and pyridine at 60-65 DEG C. and treated with potassium permanganate, in powder form or as a saturated aqueous solution, until the pink colour just persists.  The mixture is boiled and filtered to remove manganese dioxide which is washed with warm pyridine followed by aqueous sodium carbonate; the alkaline liquor is then treated with charcoal and hydrochloric acid to give diphenic acid as a white powder; 2,21-diformyl bi-phenyl may be obtained from the pyridine solution if required by mixing with ether and extracting with hydrochloric acid. In other examples, 1,21-dicarboxy-2-phenyl-naphthalene; 2,21,6,61 - tetracarboxy - biphenyl; fluorenone - 1 - carboxylic acid; 2,211 - dicarboxy - p - terphenyl - 21,31 - dicarboxylic anhydride; 9 - carboxy - 10 - (21-carboxyphenyl) phenanthrene; 2,211,31,61-tetracarboxy - o - terphenyl; phenanthrene - 9,10-dicarboxylic anhydride; 21,3 - dicarboxy - 2 - phenyl naphthalene are produced respectively from chrysene, pyrene, fluoranthrene, picene, benzochrysene, dibenzo phenanthrene, triphenylene, benzanthracene; the corresponding aldehyde may be obtained by treating the pyridine solutions as indicated above.

Title: Improvements relating to self-loading firearms
IPC: F41A9/40
Filed: 1947-01-28
Abstract: 626,374. Firearms. CESKA ZBROJOVKA, NARODNI PODNIK, MALINA, J., POLANKA, V., and KRATOCHVIL, J. Jan. 28, 1947, No. 2605. Convention date, Aug. 8, 1945. [Class 92 (ii)] An automatic or a self-loading firearm is so constructed that upon firing a round and whilst the breech bolt is still closed a gas piston device moves forwards against the action of an energy storage device, such as a spring 17, to stress breech bolt and striker mechanisms, the energy of the storage device being subsequently used to open the breech together with its stressed mechanisms and to eject the cartridge case. In the construction shown, the pulling of the trigger depresses a sear 11, thus releasing the striker 10 which flies forwards under the action of a spring 8 to strike the cartridge N1. A part of the gases of explosion pass through a port 14 into a cylinder 15 to drive forwards a hollow piston 16 against the action of its spring 17. The piston is connected by a rod or rods 9 to a member 2 which is carried forwards against the action of a spring 7 until it latches with the breech block 1. In this movement both the breech bolt'spring 7 and the striker spring 8 are compressed. When the shot has left the barrel the spring 17 asserts itself and drives the parts 1, 2, 16 to the. rear. At the end of this stroke a projecting part 4b of the guide rod 4 of spring 7 strikes the wall 6 of the gun and thus enables the latch 3 to release the breech-block 1 which moves to the breech-closing position firstly under the action of springs 7 and 8 and subsequently, when the striker is held by the sear 11, under the action of spring 7 alone.
