Inventor: VICKERS HERBERT H
IPC: B01F23/47
Filed: 1951-03-13
Abstract: Solutions of high molecular weight polymeric materials in liquids compatible therewith are prepared by extruding the polymer, passing the extruded polymer successively through a series of orifices and mixing chambers, the orifices being progressively diminishing in size, and admixing hot pressurized liquid with the polymeric material at the successive orifices and mixing chambers.  The extruded polymer may be passed through a series of screens before entering the first mixing chamber.  The process may be applied to the production of solutions of polyisobutylene, copolymers of isobutylene with olefinic substances such as styrene, polymers or copolymers of vinyl chloride and/or vinyl acetate, and polyethylene, in materials such as hydrocarbon wax, asphalt, lubricating oils, petroleum naphthas, gasoline, kerosene, ketones and esters.  The process is particularly applicable to the production of oil solutions of high molecular weight copolymers of isobutylene and butadiene and/or isoprene.ALSO:Solutions of natural and synthetic rubber in liquids compatible therewith, particularly oils, are prepared by extruding the rubber, passing the extruded rubber successively through a series of orifices and mixing chambers, the orifices being progressively diminishing in size, and admixing hot pressurized liquid with the rubber at the successive orifices and mixing chambers.ALSO:The invention of the parent Specification is modified in that after the board is compressed and cooled it is moistened with water to raise the moisture content to at least 6 per cent.  The resin is preferably a phenol-formaldehyde, urea formaldehyde, or furfural resin and may be used in a quantity of 5 to 8 per cent. based on the weight of the mixture being moulded.

Patent GB-639656-A (GB)
Title: Improvements relating to apparatus responsive to variations of amplitude of an alternating voltage
IPC: G05F1/153
Filed: 1947-03-07
Abstract: 639,656. Automatic voltage control systems; converting. ENGLISH ELECTRIC CO., Ltd., and ROBINSON, A. A. March 7, 1947, No. 6417. [Classes 38 (ii) and 38 (iv)] In apparatus responsive to variations in amplitude of an alternating voltage a thermionic valve amplifier, giving an output dependent on the variations, is provided with a grid-tocathode circuit in which a coupling condenser, the negative-going output of an unsmoothed full-wave rectifier having the alternating voltage as input, and a source of negative bias, are in series, while, to develop a voltage across the coupling condenser nearly equal to the peak of the full-wave rectifier output, a resistance is connected in parallel with a rectifier, conductive towards the grid, between the grid and the positive terminal of the negative-going output. Relays 10 and 12 operate in response to variations in voltage of an A.C. source 11 so that above a predetermined voltage, relay 10 is energized to close its contacts and run a reversible servomotor (not shown) in one direction to decrease the voltage and below a predetermined voltage relay 12 is de-energized to close its contacts and run the servomotor in the opposite direction to increase voltage. This is achieved as follows. Full-wave rectification by diodes 14 and 15 of the output of a transformer 13 connected to source 11 produces across a resistor 16 unsmoothed pulsating D.C. voltage from which is derived by a diode 18 a steady D.C. voltage, across a condenser 17, nearly equal to the peak value of the pulsating D.C. voltage. The pulsating and steady D.C. voltages thus obtained are combined in opposition to produce positive pulses in the gridcathode circuit of a tetrode 20 biassed beyond cut-off from a potentiometer 23. The output of tetrode 20 supplies, through a pulse transformer 26, sharp positive pulses, dependent in amplitude on the voltage of source 11, to the grid-cathode circuits of thyratrons 29, 30, negatively biassed at 28. The anode supplies to thyratrons 29, 30 which control relays 12 and 10 respectively are obtained through a transformer 31 from an A.C. source 32 the voltage of which leads the voltage of source 11 by 60 degrees. The secondary winding of transformer 31 is tapped to apply to thyratron 29 an anode voltage greater than that applied to thyratron 30 so that the desired operation of the relays is obtained. The provision of cathode bias of different magnitudes for thyratrons 29 and 30 is referred to. The voltage of source 11 is set to the desired value by adjustment of potentiometer 23.

Title: The process of manufacturing a curative for asthma and all analogous allergic diseases
IPC: A61K35/30
Filed: 1952-08-28
Abstract: A medicine for curing asthma and other allergic and similar diseases is made from pathological organs or tissues such as testicles, brain or skin of animals which has been inoculated while alive with viruses or micro-organisms by grinding the organs or tissues, pressing the ground materials to obtain a liquid having denatured protein ingredients, sterilizing the liquid without coagulating the proteins and then filtering the liquid. The inoculation is preferably effected with cow-pox virus, various sterilized mould extracts together with distilled water or physiological salt solution may be added to the liquid prior to sterilization and filtration.  The sterilization may be effected intermittently at 60 DEG  C. and pH 5.0-8.0, say 60-100 DEG  C., if the pH exceeds 7.0, but preferably the pH is adjusted to above 7.5 and the product is heated for 30 minutes at a temperature of 60-90 DEG  C. and allowed to stand for 24 hours; this process being repeated several times.  According to an example, skin-tissues of rabbits which have been vaccinated while alive with cow-pox-lymph, are cut up to a small size, repeatedly washed with saline solution, and ground as small as possible with sand in a mortar. Distilled water is then mixed with the ground tissue and the mixture is filtered under pressure.  The filtrate is mixed with distilled water, peptone and aspergillus oryzae.  The product is mixed with ground testicles or brains of cows or rabbits obtained from an animal which has been inoculated while alive with cow-pox virus.  After filtration, the mixture is adjusted to pH 8.0-8.5 by the addition of sodium hydroxide and is sterilized at 90-100 DEG  C.

Abstract: 548,568. Gauging-apparatus. SHEFFIELD CORPORATION. May 21, 1941, No. 6544. Convention date, June 19, 1940. [Class 106 (ii)] The workpiece is placed on an accurately finished gauging surface and a flow of fluid produced which leaks into the atmosphere through the space between the gauging surface and the workpiece, the difference between this and a similar leak when a standard piece is on the surface being measured by the height of a float in a graduated tube in the flow circuit. The workpiece 11 is received on a cylindrical member 10 provided with machined surfaces 14, 15 of slightly less diameter than correct bore separated by a groove 13. Air is supplied from a pipe 63 to a deposit trap 65 and on through a reducing valve 67 to a pipe 50. This enters a lower fitting 46 between which and a top fitting 39 a transparent tube 49 is clamped having a slightly conical bore the larger diameter being lowermost. A guide rod tensioned by nuts 57, 60 extends centrally of the tube on which slides an indicating weight 56 of slightly less diameter than the tube. The air passes from the pipe 50 through the clearance between the weight 56 and the tube through a connection 38 to a pipe 37. This communicates with a bore 16 and hence by radial bores 17 with the groove 13. Leakage past the surfaces 14, 15 takes place via grooves 20, 22 and passages 21, 23 to the atmosphere. A standard article is placed on the member 10 and the valve 67 regulated by screw 68 so that the indicating weight 56 takes up a position about half-way up the tube. The work to be gauged is substituted and variations from this position noted on the scale. If the work is to be gauged as shown at two places separated by a distance, a second transparent tube 49 and weight 56 are fitted together with machined surfaces 25, 26 and gauges supplied through a duct 30. The tubes are arranged side by side and the scales fitted with pairs of sliding markers which may be adjusted to suitable limits. Specification 367,700 is referred to.
