Abstract: 1,192,889. Separators for alkaline secondary cells. McDONNELL DOUGLAS CORP. 4 June 1968, No. 26659/68. Heading H1B. [Also in Division C1] The separator 48 of a battery consists of a porous sintered solid solution of magnesium silicate and either zinc silicate or iron silicate (see Division C1). The battery has a polytetrafluorethylene case 34, two reservoirs 58 and 59 holding the potassium hydroxide electrolyte and through which silver terminal wires 54 and 56 pass. These wires 54 and 56 are joined to the nickel screens 53 and 58 which are in contact with the electrodes 44 and 46. Potassium titanate papers 45 and 45<SP>1</SP> separate the electrodes from the separator 48. Suitable electrode combinations are silver-zinc, silver-cadmium, and nickel-cadmium. Silver electrodes are made by compacting equal weights of silver and silver oxide and prepared for use by electrolytic oxidation or by charging in 30% potassium hydroxide. Zinc electrodes are made from a mixture of zinc oxide and 3 wt. per cent mercuric oxide and prepared by electrolysing with 30% KOH.

Filed: 1965-06-23
Abstract: 1,095,004. Ice-making. GENERAL FOODS CORPORATION. June 23, 1965, No.26686/65. Heading F4H. A carbon dioxide hydrate is obtained by contacting a film of an aqueous liquid maintained at between - 3‹ and 10‹ C. with carbon dioxide gas under pressure, and allowing the dissolved carbon dioxide to react with the aqueous liquid to form the hydrate. The resultant liquid/hydrate slush may be transferred to a freezing zone where the liquid in the slush is frozen at less than - 3‹ C., or the hydrate may be separated from the liquid and stored at less than 0‹ C. The process may be performed in the illustrated apparatus in which carbon dioxide gas from line 28 and water from line 26 are combined in line 30 and supplied to a heat exchanger 10. Wipers 50 form the water into a film on wall 12 and the film is maintained at the desired temperature by a refrigerant jacket 14. The water/hydrate slush is transferred from the heat exchanger to moulds 18 in a propylene glycol freezing bath via a line 22 which contains a throttling valve 20 for maintaining a constant pressure in heat exchanger 10. The aqueous liquid may alternatively be whole or skimmed milk, fruit or vegetable juices, coffee, tea, nectar extracts or ice cream. Examples of operating pressures and flow rates are given. Part of the liquid may be removed from the liquid/hydrate slush before freezing.

Title: Improvements relating to the production of chromium phosphates
Inventor: CORBRIDGE DEREK EDGAR CHARLES
IPC: C01B25/37
Filed: 1965-06-24
Abstract: A chromium phosphate-containing product is prepared by a process in which a thermally decomposable chromium compound and a phosphorus oxyacid or an alkali metal or alkaline earth metal salt of a phosphorus oxyacid each in the form of an aqueous solution are dispersed in a gas stream, the proportions being such that there is at least one atom of phosphorus for each atom of chromium and the chromium compound is thermally decomposed in the stream in the presence of the phosphorus oxyacid or the phosphorus oxyacid salt. When the oxyacid salt is used the atomic ratio of chromium to phosphorus may be in the range 1 : 1 to 1 : 5.  The product may contain from 20 to 35% by weight of phosphorus and from 40 to 15% by weight of chromium.  The two solutions may be combined before spraying into the gas stream, or both the reaction components may be dissolved in the same solution.  The heat required may be generated by the combustion of fuel in the gas stream and may be a liquid fuel, e.g. paraffin or other mineral oil mixed with one or both of the solutions.  The solutions may also be dispersed in a burning mixture of gas, e.g. coal gas or butane and air.  The chromium compound may be chromic acid or sodium dichromate. The temperature may be 400-1200 DEG  C. The product is recovered by means of an air filter or by spraying with water and filtering.  The apparatus of Specification 1,038,773 may be used.

Title: Improvements in or relating to polymerisation processes
IPC: C08F20/44
Filed: 1957-08-26
Abstract: The process of the parent Specification for preparing white acrylonitrile polymers is modified in that in a continuous process for preparing acrylonitrile polymers containing at least 85% of acrylonitrile by polymerizing acrylonitrile, with or without copolymerizable ethylenically unsaturated compounds, in aqueous media containing as catalyst a water-soluble salt of perdisulphuric acid and as activator a water-soluble oxidizable sulphoxy compound wherein the valence of the sulphur does not exceed 4, the weight ratio of sulphoxy activator to peroxy catalyst being at least 5 to 1, wherein the proportion of monomeric material is such that a slurry of solids content 18% or more would normally result, the slurry consistency is reduced by having present during polymerization an anionic surface-active agent.  The surfaceactive agent may be alkali metal, e.g. sodium, salts of long chain alkyl sulphates, e.g. sodium lauryl sulphate, sulphonated hydrocarbons and sulpho derivatives of dicarboxylic acid dialkyl esters, e.g. sodium dioctyl sulphosuccinate, potassium dihexyl sulphosuccinate, ammonium dibutyl sulphosuccinate and sodium diethyl sulphosuccinate.  Specified activators are sodium bisulphite, sodium metabisulphite, sodium hydrosulphite and sodium thiosulphate, and the exemplified catalyst is potassium persulphate.  The pH of the media may be adjusted, e.g. with sulphuric acid.  Many suitable copolymerizable compounds are listed, included anhydrides, esters, amides and N-substituted amides of unsaturated acids; esters of unsaturated alcohols; unsaturated heterocyclic compounds, ethers and ketones; vinyl and vinylidene halides and salts of unsaturated sulphonic acids; and the examples describe the copolymerization (I, II and III) acrylonitrile, methyl acrylate and sodium styrene sulphonate and (IV) acrylonitrile and methyl acrylate.

Title: Process and apparatus for generating cold
IPC: F25B9/14
Filed: 1947-10-08
Abstract: 642,153. Refrigerating; heating and cooling gases. TACONIS, K. W. Oct. 8, 1947, No. 27075. Convention date, Oct. 28, 1946. [Classes 29 and 64(iii)] A process for generating cold comprises cooling a gas such as air, hydrogen or helium at constant or practically constant volume, heating it to its original temperature at constant or practically constant pressure, and compressing it. A heat insulated cylinder 1 contains four displacers 2-5 moved by rods 6-9 and has a temperature gradient maintained in it, hot at the top, cold at the bottom. Compressed air is admitted from a reservoir 15 by a valve 11 which is then closed. The displacers are.raised one by one so transfering the gas down the cylinder, the gas being cooled at constant volume. The cylinder is then put in communication with a lowpressure reservoir 13 by a valve 12 and the displacers are lowered thus raising the gas which is heated at constant pressure. Gas is withdrawn from the reservoir 13, compressed and fed to the reservoir 15. Cold gas may be bled from the bottom of the cylinder. The reservoir 13 may be at a lower pressure than the cold part of the cylinder. The top of the cylinder may be water cooled. The device may be used -for cooling compressed air in a coil around the cylinder prior to liquefaction. Two units may be used 180 degrees out of phase. In modifications the gas may be supplied direct from a compressor at the start of a cycle, from a small compressor during the whole gas-cooling period or from reservoirs at different pressures during the gas.cooling period, these reservoirs being connected by small compressors. The cylinder wall or the displacers may act as a regenerator.
