Filed: 1970-07-30
Abstract: 1362777 Pressurized dispensing containers COOPER McDOUGALL & ROBERTSON Ltd 13 July 1971 [30 July 1970] 36820/70 Heading F1R A cartridge for dispensing liquid, for example insecticide, comprises a pressurized insecticide container 6 with a discharge valve actuated by a force from outside the cartridge, located within a canister 1 for carrier liquid 14; the canister having membrane 5 adapted to be pierced by an outlet pipe 23, 25. The cartridge is located withi n a housing which has a plunger 27 which can press on a flexible membrane 4 and actuate the discharge valve to discharge the contents on the container 6 into the carrier liquid through bores 12, 13, at the same time as member 23 pierces membrane 5. A spring 18 located between a support member 9 and a spider 15 prevents accidental discharge from the cartridge if the canister is jarred. The mixture may either be pumped from the canister or it may be dispensed by gas pressure from propellant stored in the container 6. In another embodiment the container 6 may be supported directly by the spider 15. Alternatively, Fig.5a, the spider 15 may have an integral actuating member 40 which acts on valve 37 so that movement of the container 34 towards the spider 15 opens a passage through orifices 42, past rim 39 and through notches 43 to passage 44 into the canister. With this valve the piercing member may also serve to actuate the valve by moving the spider. The membranes 4, 5 may be protected by foil covers 20, 21 prior to use and the piercing member 23 may have a second passage through which liquid can be returned to the cartridge. The cartridge may be used to dispense insecticides in aircraft through the air conditioning system.

Filed: 1954-12-28
Abstract: 757,018. Cooling meat &c. UNION STOCK YARD & TRANSIT CO. of CHICAGO. Dec. 28, 1954, No. 37466/54. Class 29. Perishable products such as meat, flowers, fruit or vegetables are chilled and refrigerated by treating with refrigerated, supersaturated air to prevent dehydration of or deposition of slime on the products. As shown, sides 40 of meat are suspended in a chamber 11 from which air is withdrawn through an opening 17 by a rotary compressor 21. The air then flows over cooling coils which remove the heat of compression and reduce its temperature approximately to that of the air leaving the chamber 11, the air being approximately saturated. The air is then expanded in turbines 33, 34 which assist the motor driving compressor 21 and it is stated that, instead of moisture being deposited from the resulting chilled air, it becomes supersaturated. The chilled air then re-enters chamber 11 through openings 16. The supersaturation is controlled either by varying the speed of the compressor or by restricting the air flow into the compressor or by both means. The amount of refrigerant supplied to the cooling coils may be controlled in response to the temperature of the air cooled thereby. In the initial stages, it may be necessary to add moisture to the chamber. U.S.A. Specification 2,065,358 is referred to.

Title: Method and equipment for the production of polymerization products from polymerizable ethylenically-unsaturated compounds
IPC: B29C48/405
Filed: 1964-08-18
Abstract: Polymers are continuously produced from ethylenically-unsaturated compounds, which are solid or liquid at 18-22 DEG C., by polymerization in a tubular reactor with forced feed at 10-1000 atmospheres and 100-300 DEG  C., the molten polymer being subjected to shear forces. The shearing reduces the molecular weight of the polymer and may be carried out in an extruder, which may also form the reactor.  The monomers may be styrene together with acrylonitrile and/or methyl methacrylate, or acrylamide. Polymerization may be in bulk using a free radical forming catalyst, e.g. azo-diisobutyronitrile, benzoyl peroxide or cumene hydroperoxide. Monomers or oligomers may be removed from the polymer in a degassing zone. The polymer may be formed into a strand, which may be granulated, or into a transparent sheet. Apparatus for carrying out the above process is described and illustrated by Figs. 1 and 2 (not shown).
