Title: Improvements in the production of rubber-polymer mixtures and compounds
Inventor: ANGIER DEREK JOHN
IPC: C08F291/02
Filed: 1955-02-14
Abstract: Rubber/polymer compounds and mixtures are prepared by the mastication at a temperature in the range within which rubber molecules are ruptured by the applied shear, and under substantially oxygen-free conditions, of a mixture of natural or synthetic rubber and a polymerizable olefinic compound of such proportions that the mixture is rubbery at the temperature of mastication.  The rubber may be natural rubber, preferably crepe that has been treated with acetone to remove non-rubber constituents, or a synthetic rubber such as polybutadiene-1,3, or a copolymer of butadiene-1,3, with acrylonitrile, styrene, isobutylene, methyl methacrylate, methyl acrylate, polychloroprene, or polyisobutylene, or an isocyanate-modified polyester or polyesteramide.  Antioxidants and "chain stoppers" are first removed from the synthetic rubber by fractional precipitation.  The polymerizable olefinic compound may be acrylic acid, methyl, ethyl, or n-butyl acrylate, methacrylic acid, methyl, ethyl, n-butyl, isobutyl, 2-ethoxy-ethyl, 2-chloro-ethyl, nonyl, lauryl, b -ethyl ethoxy, or 2-chloroethyl methacrylate, acrylonitrile, methacrylonitrile, acrylamide, N-butyl acrylamide, vinylidene chloride, methyl isopropenyl ketone, styrene, methyl vinyl ketone, N-vinyl pyrollidone, 2-vinyl pyridine, or vinyl carbazole, divinyl benzene, chloroprene, allyl acrylate, or methacrylate, 2,5-dichlorostyrene or ethylene dimethacrylate. The mixture to be masticated may contain two or more rubbers and/or two or more polymerizable olefinic compounds.  The rubber or rubbers may be masticated with one olefinic compound before another is added.  The mastication is effected on milling rolls or in an extruder or a liquid-cooled internal mixer in which an atmosphere of nitrogen or carbon dioxide is maintained.  The temperature of the mixture during mastication should not normally exceed 130 DEG  C. and is preferably maintained below 70 DEG  C. Vulcanization of the rubber component and/or cross-linking of the polymer component may be effected during or after the mastication by the addition of the necessary agents, e.g. methylmethacrylate polymer may be cross-linked by adding di-cumyl peroxide.  Several examples are described.  Specification 679,562 is referred to.

Abstract: 1,031,346. Centrifugal pumps. G. NEIDL. Feb. 6, 1963 [March 23, 1962], No. 4880/63. Heading F1C. [Also in Division H2] A submersible centrifugal pump 351 is con nected to its driving motor 350 by an intermediate member 352. The presence of air in the space between the motor and the intermediate member 352 may be avoided by filling it with insulating material 357. The total air space remaining within the motor and the intermediate member above an annular cavity 359 is small compared with the volume of the cavity so that, when the pump is submerged, equilibrium between the static pressure of the liquid and the pressure of the air is reached when the liquid has risen in the cavity to a level 372 which is below the lower bearing 371. The motor 350 may be controlled automatically in accordance with the liquid level, being switched on when a maximum level is reached. The motor is automatically slowed down when the level has fallen to the upper edge 361 of the pump and is stopped when the level has fallen to the lower edge 360. At this instant, frothing occurs between the liquid and the air so that air enters the pump to relenish the air cavity 359. The pump is of the type having an oblique-disc rotor 363 which may have circumferential teeth engaging circumferential grooves 364. Two discharge branches 367 are provided.

Title: Improvements in or relating to the treatment of meat
IPC: A23L13/70
Filed: 1938-02-17
Abstract: 510,813. Tendering meat; irradiating meat ; preserving meat. SHEPHERD, G. R. (Westing- house Electric & Manufacturing Co.). Feb. 17, 1938, No. 4924. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 21, 1938.] [Classes 28 (ii) and 49] [Also in Group III] Meat is made tender by maintaining it under such conditions of temperature and humidity that the enzymic digestion weakens the connective tissue, whilst the growth of aerobic bacteria is retarded by irradiation with ultraviolet light. A lamp or lamps generating a strong spectrum in the region between 2500- 3000 A‹ with substantially no radiation below about 2500 A‹ and in the infra-red region, is preferably used. Treatment temperatures of from 55‹F. to 98‹F. and humidities of from 90 per cent. to 100 per cent. are referred to. The high humidity prevents evaporation losses from the meat. The surface of the meat may be protected from the drying effect of the hot lamp, by coating it with an air excluding fluid, e.g., a colourless, odourless, good grade of mineral oil, pervious to ultra violet light. The lamp may be operated for a part, e.g., one third, of the time, and the retardation of the growth of bacteria may be effected by air which is circulated past the lamp and is thus activated. As shown, the meat 4 is supported on shelves or racks 3, and a natural air circulation occurs past the attemperating coils 5 and the lamps 6, which latter are controlled by a switch 7 through a transformer 8. Tracks 9. are provided for moving the meat. Humidifying means are provided. In modifications, the lamps are at the side of the chamber, and the air circulation is produced by a fan; or the lamps and humidifying means are in an external conduit connected with a fan which draws air from the bottom of the chamber and passes it through the conduit into the top of the chamber, or vertically disposed lamps and, if necessary, horizontally disposed lamps are arranged to effect direct irradiation of the meat. When the meat has been sufficiently tenderized it is placed in a high humidity refrigerator where the tendering process is arrested. Such refrigerator may contain ultra-violet lamps. Alternatively, the meat may be refrigerated in the treatment chamber.

Abstract: 1,179,971. Mass spectrometers. VARIAN MAT G.m.b.H. 31 Jan., 1968 [8 Feb., 1967], No. 5024/68. Heading H1D. [Also in Division G3] In apparatus of the type in which the control or measurement of a magnetic field is involved, and in which deviations, such as temperature dependent variations, in a stray field associated with the main magnetic field may affect the control or measurement, there is provided a system which compensates for the effects of such deviations. As shown, a field sensor S 1 , e.g. a Hall probe, is located in the field gap of the separating magnet M of a mass spectrometer and produces a signal representative of the gap field strength; this signal is applied over a voltage divider T 1  to a summing stage S which also receives inputs over respective voltage dividers T 2 , T 3  from further field sensors S 2 , S 3  located in the stray field which is associated with the magnet M and which can vary and thus affect the accurate operation of the spectrometer. The voltage dividers T 1 , T 2 , T 3  allow the individual outputs from the sensors to be adjusted to provide the desired compensating effect, and the summed output Vs from the stage is thus representative of the total field produced by the magnet M. This output Vs can be applied to an indicating device, or it may be employed, using known circuitry including a compensator D, an amplifier, and a magnet field controller St as shown, to control the total field in such a way that the ion deflection in the spectrometer remains constant despite variations in the stray field relative to the field in the magnetic gap.
