Abstract: 724,106. Band clips. ROBINSON, J. S. L. Feb. 5, 1953 [Feb. 5, 1952], No. 3015/52 Class 44. In a hose clip of the worm drive type the means for supporting the lower side of the head-end of the worm from the top of the housing consists of a lug integral with the housing and perforated for the worm. In the arrangement shown a housing 4 for a worm 1 is provided with a depending lug 5 bent at rightangles to the top of the housing. The lug is formed with a hole 6 for the worm and projects beyond the face of the housing where it is turned back on to the sides of the housing. The other end of the worm is provided with a washer 7 which is maintained in position on the end of the worm by rivetting. In another arrangement (Figs. 6-8, not shown) the top of the housing is provided with a forked lug which is bent down at right-angles to form a bearing for that end of the worm. According to the Provisional Specification in a further arrangement Figs. 9-11 (not shown) the lug is replaced by a flanged washer engaging the top surface of the housing. The washer may have side flanges engaging the sides of the housing. In modifications, the washer may be forked and may be belled out to fit over the top of the housing and include flanges engaging the sides thereof. According to Fig. 15 (not shown) the housing is rectangular in cross-section and is provided with a lug as in Figs. 2 and 5 and with a forked lug as in Figs. 6 to 8.

Title: Improved nuclear reactor system
IPC: G21C1/14
Filed: 1962-01-26
Abstract: 938,159. Reactors. GENERAL DYNAMICS CORPORATION. Jan. 26, 1962 [Jan. 30, 1961], No. 3077/62. Drawings to Specification. Class 39 (4). In a light or heavy water-moderated reactor, the core may be moved horizontally between two positions at opposite ends of the reactor tank. At one of the positions irradiation of test objects is effected with fast neutrons and at the other position irradiation by moderated or thermal neutrons may be employed. The reactor can be operated at a steady output or it may produce a short pulse of power, of high amplitude, by the rapid operation of a controlrod. The reactor tank and the two irradiation positions are mounted within a concrete shield. The fast neutron irradiation position is lined with wood and is floored with epoxy resin. A lead shield, mounted between the reactor and irradiation position is retractable into the floor. The thermal irradiation position is shielded from gamma rays and fast neutrons by concrete blocks and a heavy water tank and radiation from the core into the position is effected through a port in a lead sheet. To permit safe access into one irradiation position while the other is in use, a movable radiation shield is mounted in the tank, between the two positions, formed of an aluminium housing filled with lead shot. The fuel material is a mixture of uranium 235 zirconium hydride and uranium 238. Specification 852,877 is referred to.

Abstract: 1,248,181. Segmented polyurethane elastomers. FARBENFABRIKEN BAYER A.G. 22 Jan., 1970 [22 Jan., 1969(2); 24 March, 1969], No. 3112/70. Heading C3R. [Also in Division C2] Linear, segmented polyurethane elastomers are prepared by reacting an isocyanate terminated prepolymer containing 2 isocyanate groups with a chain lengthening agent, at least 55 mole per cent of which is a semi-carbazide amine of the formula wherein R is -(CH 2 ) y - (y=2 to 6); mcr pphenylene, wherein X=0, 1 or 2. The prepolymers may be prepared from conventional diisocyanates and polyethers, polyesters or polycarbonates. The semicarbazide amines may be used in admixture with known chain lengthening agents. The chain lengthening reaction is suitably carried out in an inert organic solvent. Particularly good semicarbazide amine chain lengthening agents are #-semicarbazide ethylamine, 4- aminophenyl - semicarbazide, 3 - aminophenylsemicarbazide, 4 - aminobenzyl - semicarbazide and 4 - aminodiphenylether - 4<SP>1</SP> - semicarbazide. The semicarbazide amines may be used in the form of their carbonates. In a typical example a polyester derived from adipic acid, 1,6-hexane diol and 2,2-dimethyl propane diol is reacted with N,N-bis-(#-hydroxypropyl)-methylamine and diphenylmethane - 4,4<SP>1 </SP>- diisocyanate in chlorobenzene to form a prepolymer which is reacted with #-semicarbazido-ethylamine carbonate in dimethylformamide. The elastomer solution is pigmented and reacted further with hexane-1,6-diisocyanate and wet-spun to form filaments.

Sodium perborate. obtaining, from an electrolyte containing an alkaline borate and carbonate, by a process of the kind described in the parent Specification. According to the present invention, reduction at the cathode is diminished by adding to the electrolyte a substance or mixture capable of producing on the cathode a precipitate which lowers the reducing action. Suitable substances are chromic acid and chromates of bases incapable of decomposing the perborate, for instance alumina, alkalis, or alkaline earths, including magnesia and beryllia. Other alkaline-earth salts, such as calcium chloride, may be employed. There may also be added, to further the action of the above substances, protective colloids such as albumen, starch, and gum arabic. Preferably no diaphragm is used.
