Abstract: 328,123. White, C. B. April 30, 1929. Metal-heating furnaces. - The lead and filling material of old accumulator plates are recovered separately by heating the plates to melt the lead which runs off and is collected in a receptacle, the filling material being then projected on to a cooler body having a rough surface. The material is thus disintegrated, the entrapped lead adhering to the rough surface while the filling material rolls off and is collected separately. Fig. 1 shows apparatus for carrying out the process. The plates 15 are carried on a conveyer through a furnace 5, where the lead is melted and runs through perforations in the ribbed plates 2 forming the conveyer.

Abstract: 528,544. Kinematographic gelatine relief images. TECHNICOLOR MOTION PICTURE CORPORATION. May 9, 1939, No. 13838. Convention date, Dec. 13, 1938. [Class 98 (ii)] In the production of kinematographic gelatine relief images, gelatinous pellicles tending to bridge the feed perforations are broken and removed before the film is dried to prevent the pellicles breaking and spattering the film during the drying process. The feed perforation zone of the film is scrubbed without scrubbing the picture zone, and the gelatinous material is rinsed away. As shown, the film F is treated in the tank 1 with warm water from the nozzles 4 and 5, to produce the gelatine relief, and is then passed to scrubbing means S comprising a backing roller 9 in adjustable bearings and a scrubbing roller B comprising two discs connected by a cylindrical portion and recessed on their outer peripheries to receive spongerubber rings serving as brushes, the spongerubber rings being held on the discs by clamping rings and screws. The rings are spaced apart by the distance between the two rows of feed perforations. The backing roller 9 is rotated by frictional engagement with the film and the scrubbing roller B is driven oppositely to the motion of the film. The loosened gelatine is washed away by the rinsing jet 13. A rinsing tank 11 is provided.

Abstract: 1,148,125. Ammonium perchlorate. UGINE KUHLMANN. 28 March, 1967 [29 March, 1966], No. 14102/67. Heading C1A. Substantially pure, anhydrous ammonium perchlorate is produced by reacting an alkali metal perchlorate with ammonium sulphate, in a solvent, other than water, in which ammonium perchlorate is more soluble than the alkali metal sulphate, e.g. liquefied anhydrous ammonia, filtering the resultant suspension, and extracting the ammonium perchlorate by allowing the solvent to evaporate from the filtrate. The alkali metal perchlorate may be sodium perchlorate. Filtrate solutions may contain up to 55% by weight of ammonium perchlorate. The reaction may take place in an autoclave, and ammonium perchlorate may be separated from the filtrate by depressurization in an autoclave containing a saturated solution of ammonium perchlorate from a previous operation.

Title: Improvements in Vacuum Fuel Feed Devices.
Inventor: WHITE ALFRED ERNEST
IPC: F02M37/02
Filed: 1918-09-02
Abstract: 123,280. White, A. E., (Stewart-Warner Speedometer Corporation). Sept. 2, 1918. Vacuum apparatus.-Relates to the actuation of the atmospheric valve in liquid-fuel supply devices wherein fuel is raised by suction from a main to an auxiliary tank whence it flows by gravity to the carburettor. The auxiliary tank 4 encloses the float tank 2 which is connected at 26 with the source of suction and through a pipe 3 with the main tank 1. The tank 2 discharges through a pipe 27 with check valve 28 into the chamber 4, which is always open to the atmosphere through the pipe 25. Atmospheric pressure is transmitted to the tank 2 through a pipe 14, 15 controlled by a valve 12 actuated by a pair of floats 10, 11. The floats slide over a guide rod 6, Fig. 2, carried by a frame 7, 9 and the valve 12 is attached to the lower float 10. This float carries a bar 22, the upturned ends 22<a> of which actuate the arms 20 of bell-crank levers, the other arms 21 of which are adapted to engage a stop 24 carried by the upper float 11 when in its lowest position. With this arrangement, the lower float 10 is held locked and therefore the valve 12 closed until the fuel has risen sufficiently high to raise the float 11 so as to withdraw the stop 24 from the arms 21. The levers are then released and the float 10 and valve 12 are lifted suddenly. In a modifioation, the floats slide over the stem of the valve, the opening of which is assisted by a spring compressed between the top of the upper float and a pin in the stem. In a further modification, the floats slide over the stem and actuate the valve, which opens downwards, through three-armed lovers.

[Class 98 (i)] Screens for X-ray work, luminescent signs, &c. containing zinc sulphide are rendered more resistant to deterioration due to daylight or atmospheric influence by treating the luminescent layer after its formation with an alkali silicate solution, e.g. a 3-25 per cent solution of water glass, which may be rendered alkaline as by adding 5-20 per cent of alkali hydroxide solution, and thereafter superficially rinsing the layer to remove the silicate. The screen layer, containing the luminescent material in a binder such as cellulose nitrate lacquer, cellulose acetate lacquer, resin or a polystyrene, may be first formed on a glass plate, from which it is stripped and immersed for several hours in the treating bath, which must be rendered alkaline for a layer having a polystyrene binder. After treatment, the layer is rinsed with water, dried, and mounted on a pasteboard, artificial resin, or like base. In examples, the treatment of a zinc-cadmiumsulphide screen in a cellulose nitrate lacquer or polystyrene binder, is described.

Title: Improvements in the preparation of tetrafluorethylene
Inventor: FARLOW MARK WENDELL
IPC: C07C17/367
Filed: 1955-05-19
Abstract: A process of preparing tetrafluoroethylene comprises pyrolysing a fluorocarbon having a melting point of not more than 25 DEG  C. and the formula CxFy wherein x and y are positive integers, x being at least 3 and the ratio of y to x less than 2.7 : 1, at a temperature of at least 1500 DEG  C., and cooling the pyrolysis mixture from the pyrolysis temperature to below 400 DEG  C. in not more than one second.  Preferably, after the separation of the tetrafluoroethylene product, the remainder of the fluorocarbon mixture is recycled for further pyrolysis.  The pyrolysis may be effected by heating in a carbon are, or by heating in a refractory tube, preferably at 2000 DEG  to 4000 DEG  C. With fluorocarbons having a carbon to fluorine ratio of more than 2 : 1, carbon electrodes are beneficial.  Below this value electrodes of tungsten or zirconia can be used.  The pyrolysis can also be effected in reaction vessels made of or packed with carbon such as coal, graphite, diamond, lamp black, acetylene black, bone black, coke or active carbon.  Preferred cooling times are between 0.001 and 0.1 seconds.  When the are is passed through fluorocarbon vapour low pressures, e.g. 1 mm. are preferred. Superatmospheric pressures may be used when the are passes between electrodes submerged in the liquid fluorocarbon.  The product of pyrolysis also contains hexafluoropropene, octafluoropropane, carbon tetrafluoride and hexafluorethane, the two latter being convertible to tetrafluoroethylene by the process of Specification 760,657.  The separation of the product can be effected by fractional distillation, selective adsorption or selective solvent extraction.  Examples describe the pyrolysis by means of a carbon are of the vapours of octafluoropropane, hexafluoropropene and perfluorodimethylcyclohexane isomers (from the exhaustive fluorination of mixed xylenes) and of perfluorodimethylcyclohexane as a liquid.  Other suitable perfluorocarbons are perfluoro-1,3 - butadiene, octafluorocyclobutane, decafluorobutane, and perfluorocarbons from the exhaustive fluorination of petroleum fractions, e.g. perfluorinated lubricating oil C21H44 and perfluorinated kerosene having from 10 to 14 carbon atoms.  A flow sheet and illustrations of suitable arrangements of are for use with gaseous and liquid fluorocarbons is given.
