Title: Internal combustion engine with exhaust recirculation
Inventor: WALKER BROOKS
IPC: F02D21/08
Filed: 1969-08-20
Abstract: 1,259,889. Valves. B. WALKER. 20 Aug., 1969, No. 41668/69. Heading F2V. [Also in Division F1] The flow of gases from the exhaust pipe of an engine through conduits 16, 50 to the inlet manifold 30 is controlled by a valve 31 responsive to inlet suction. With low inlet suction in chamber 43 spring 42 holds valve member 33 against restricted section 32 so as to prevent exhaust gas flow through the valve. As suction in chamber 43 increases member 33 moves to the right to permit exhaust gas flow, the latter being controlled by the contour 36 of member 33. With a still further increase in suction member 33 moves further to the right into a position in which section 37 substantially prevents gas flow.

IPC: C08J9/00
Filed: 1971-09-07
Abstract: 1347152 Vinyl chloride polymer foam DOW CORNING CORP 7 Sept 1971 [19 Oct 1970] 41597/71 Headings C3C and C3R A process for preparing a plastisol foam, the plastisol being a mixture of a particulate thermoplastic vinyl homopolymer or a copolymer consisting of more than 50% by weight of a vinyl monomer and less than 50% by weight of a copolymerizable monomer, and a high boiling organic liquid plasticizer which is substantially a non-solvent for the particulate polymer at ordinary temperatures but is capable of dissolving the polymer at elevated temperature to form a single phase material which, upon cooling to ordinary temperature, is a solid material, comprises adding to the plastisol composition, prior to foaming, at least 1À25 parts, preferably 3-5 parts by weight per 100 parts by weight of the remaining ingredients of the plastisol composition a material which is compatible with the plastisol and cures at room temperature, foaming the resulting mixture, curing the material added at room temperature using a curing agent and finally fusing the plastisol foam. The material added to the plastisol may be a "vinylic monomer" such as acrylates and methacrylates, unsaturated polyesters, epoxy resins and polyurethanes. The term "vinylic monomer" includes monomers per se, low molecular weight polymers, and mixtures of such monomers and polymers. After foaming the foam is allowed to stand at room temperature whereupon it gels. Between the foaming of the composition and final fusing, the foam may be shaped to a desired configuration. After the composition has been foamed a vacuum may be applied to obtain a low density product, preferably having a density of less than 32 kg. (cu. metre. In the examples foaming is achieved by mechanical whipping. In Example 1 a plastisol containing PVC and a polyol modified siloxane acting as a foam stabilizer is partially foamed, polymethylene polyphenyl isocyanate is then added and the foaming continued. The isocyanate reacts with the modified siloxane to produce a polyurethane. In the other examples the compatible material is added to the plastisol prior to any foaming occurring. In these examples foamed plastisols are formed from a mixture comprising PVC plastisol and (2) a mixture of polyoxypropylene triol and a diisocyanate; (3), (9), (10) trimethylol propane trimethacrylate; (4) an epoxy resin; (5) an unsaturated polyester; (6) 1,3- butylene dimethacrylate; (7) methyl methacrylate. The plasticizers mentioned in these examples are butyl benzyl phthalate and dioctyl phthalate.

Title: Fastening system for fuel pins
Inventor: AGRANIER JEAN-GLAUDE
IPC: G21C3/12
Filed: 1970-09-01
Abstract: 1293436 Fuel elements COMMISSARIAT A L'ENERGIE ATOMIQUE 1 Sept 1970 [17 Sept 1969] 41819/70 Heading G6C A fuel assembly comprises a sheath 10 of hexagonal cross-section with a base 12 having tongues 14 by which it is retained in a grid (not shown), a number of superimposed bundles of fuel pins being disposed in the sheath 10. The lower bundle is formed by pins 16 occupied by fertile material while the second bundle is formed by pins 18 of smaller section than the pins 16 and occupied by fissile material. A thin tube 20 of hexagonal section is mounted with a small clearance in the sheath 10, being welded to an end shoulder 22 of the base 12. The pins 18 are attached to the sheath 10 by a fastening system comprising two parallel rods 24 extending transversely across the tube 20, and a number of flat rails 28 elongated in the direction of coolant flow and formed with holes 30 through which the rods 24 extend. The end plugs 32 closing the fuel pins 18 are each formed with a slot large enough transversely to admit a rail 28 and terminating in a part-cylindrical passage 34. Each fuel pin 18 is connected to the corresponding rail 28 via an intermediate guide member 36 in the form of a split tube of outside diameter such as to enable it to slide in passages 34. The slot in the guide member 36 is wide enough to enclose a narrowed portion 38 of the rail 28. The fuel pins 18 are free to slide on their guide members 36 and to move slightly transversely of the rails 28, since the latter can tilt slightly. Consequently, the fuel pins can be tightened to force them to form a compact bundle in which their distance apart is determined exclusively by the contacting of the helically wound spacing wires with which they are provided. In the embodiment illustrated, the fertile pins 16 are attached to the sheath 10 by similar means to those attaching the fuel pins 18 but they may alternatively be attached to the base 12 by conventional means.
