Title: Foamed plastics materials and process for their manufacture
IPC: C08J9/02
Filed: 1965-05-26
Abstract: Foamed synthetic resins are produced by reacting together a telomer having a low softening point and containing units of a monomer which has a hydrogen atom which is directly bonded to carbon and is activated by two electron-attracting groups, and units of a copolymerizable monomer, an aldehyde, and the reaction product of a polyfunctional primary or secondary amine and carbon dioxide. Suitable telomers include as the reactive component units of an allyl or vinyl ester of a b -keto-carboxylic acid, e.g. acetoacetic acid, or of malonic acid, or of cyanoacetic acid, an alkyl malonic acid, p-nitrophenylacetic acid, benzoyl-acetic acid, o-nitrophenyl - a  - hydroxy - acetic acid, pyruvic acid, benzoyl-methylmalonic acid, an a -alkylacetoacetic acid or 2,3-dicarboxy-propanoic acid.  Suitable monomers copolymerizable therewith include vinyl esters, e.g. vinyl acetate, styrene, acrylic and methacrylic esters, e.g. the methyl esters, ethylene and vinyl chloride.  Specified polyamines are ethylene, propylene and butylene diamines, hexamethylenediamine, piperazine and its derivatives and ethylene glycol bis g -aminopropyl ether.  The preferred aldehyde is formaldehyde, part acetaldehyde or crotonaldehyde, or a mixture of one of these with formaldehyde, may be used.  Carbon dioxide is released to foam the product, but a volatile liquid, e.g. a halogenated alkane, may be added to the composition.  A surface active agent, e.g. a siloxane/ethylene oxide or ethylene oxide/propylene oxide block copolymer may be added.

Title: Improvements in and relating to carburetors for internal combustion engines
IPC: F02M7/08
Filed: 1935-08-09
Abstract: 459,550. Spray carburetters. MOORE INVENTIONS CORPORATION, 946, Slater Building, Worcester, Massachusetts, U.S.A. Aug. 9, 1935, No. 22498. Convention date, Dec. 11, 1934. [Classes 7 (iii) and 7 (v)] In an anterior throttle carburetter, a main air throttle controls the admission of unheated air to a conduit leading to the engine cylinders and a variable, controlled quantity of air is admitted to a primary air passage into which fuel is introduced through a variable orifice, the primary mixture so formed being heated to vaporize the fuel before introducing it into the conduit in advance of the main air throttle. A rotary main air valve 18 is linked through a rod 18d to a cam shaft 16a on which a cam 16 is adapted to depress a fuel metering rod 12 during initial opening movement of the air valve, then to permit a spring 14 to raise the rod when the air valve is at a point corresponding to transition from normal to full load running and finally to depress the rod again as the valve becomes fully open. The end of the rod is bevelled at 20 to provide a sector shaped opening for the fuel which receives a primary charge of air past a valve 26 urged to close by a spring 133 but opened by suction applied through a passage 30 to the back of the valve. The rich mixture traverses a passage' 24 to a discharge tube or nozzle 24a. The maximum flow of fuel is controlled by a submerged nozzle 38 smaller than the passage 10 controlled by the rod 12. On opening the air valve 18, the spring 133 closes the air valve 26 and a smaller quantity of air is provided by a calibrated orifice 36 unless a reduction in the suction has permitted fuel to accumulate in a well portion 24u of the passage 24, the fuel then requiring to be lifted only the distance from the level lla to the shoulder 24f of the passage 24. A throttle operated pump 50 supplies fuel for acceleration through a tube 62 provided with air inlets 64 to prevent fuel from being drawn into an acceleration nozzle 58 bv suction alone. The nozzle 24a discharges into a chamber 33 divided into two passages by a nipple 33a forming part of an exhaust passage 33b and provided on its inner surface with ribs 33d. A pipe 34 conducts the vaporized mixture to the throat of a Venturi 35 disposed between the air inlet valve 18 and the induction manifold 72, which comprises upwardly extending branches provided with a floor vent 78. Fuel which accumulates around the vent facilitates starting. Small apertures 22 in the air valve 18 provide air for idling. Specification 458,698 is referred to.
