Patent GB-1289509-A (GB)
IPC: A62C13/00
Filed: 1969-10-15
Abstract: 1289509 Powder fire extinguishers CARL ESSER KG DRUCKGASARMATUREN 15 Oct 1969 50745/69 Heading A5A A fire extinguisher of the powder/pressurising gas type in which the gas is stored in an internal container sealed by a membrane comprises a valved outlet controlled by two separately actuatable levers, the first 35 in its normal position locking the second 30, but on actuation successively displacing shut-off member 20 until spike 26 pierces membrane 18 and simultaneously releasing lever 30, member 20 in its displaced position obstructing the extinguishant outlet 22 and lever 30 being operable to control 20 in respect of 22. The extinguisher comprises main body 10 filled with powder 13, and pressure gas bottle 16 secured to the lower end of valve housing 11. Shut-off member 20 is slidably mounted in axial bore 19 of 11 and carries a cylindrical lower tip 25 terminating in spike 26. O-ring seals 21, 24 are provided at two points around 20. Normally member 20 is urged by spring 28 bearing on washer 29 upwards against the underside of lever 30, which is pivotable about pin 31. A second spring 33 located in a bore in the upper end of 20 also bears against lever 30. In addition further lever 35 is mounted by means of pivot pin 36 on housing 11, with its nose 37' engaging in notch 38 of member 20. When required for use, lever 35 is pivoted upwards into the Fig. 2 position, in which nose 37 forces down shut-off member 20 until spike 26 perforates membrane 18, releasing pressure gas into chamber 39. On completion of the pivoting arc of 35, nose 37 slips down from notch 38 and releases member 20 which immediately ascends under the action of spring 28 until it again bears against lever 30 (Fig. 3). In this position O-ring 24 seals inlet 23 from the passage of the powder/gas mixture. To eject the mixture from nozzle 22 lever 30 is depressed (Fig. 4). Shut-off member 20 again descends and O-ring 24 is displaced from inlet 23, permitting extinguishant flow to outlet 22. Thus continuous or intermittent ejection may be obtained as required. After use lever 35 cannot inadvertently be restored to the Fig. 1 position, since face 40 of nose 37 bears against the outer side of 20 until member 20 is deliberately depressed, e.g. by a pronged member, to release the nose. This may be effected on recharging the extinguisher.

Abstract: 1324250 Computer checking system ELLIOTT BROS (LONDON) Ltd 15 Dec 1971 [15 Dec 1970] 59465/70 Heading G4A During execution of a program, a check sum is formed from words read out from memory and is compared at intervals with predetermined values to determine if the computer is operating correctly. Variable data words are excluded from the check sum by making the control unit 28 of the checking system responsive to special start and stop instructions or by restricting the variable data words to a predefined area of memory 11 and inhibiting the checking circuitry when an address in this area is in register 12. Unimportant sections of progiams may also be excluded from the check. With control unit operative, successive words appearing on bus 14 are fed to an adder 22 for addition to the preceding sum in register 20. On detection of a "read and clear" instruction, control units 28, 37 cause successive read-out of the two 12-bit halves of the check sum in register 20 to the central processor 10 or an external unit 46, register 20 then being reset. When the program contains branches or loops, the value of the check sum obtained will depend on the branches taken and the number of times the loops have been cycled. A correction instruction is therefore included in the program branches and loops whereby, on reaching this instruction a pair of 12-bit words are read from memory and are supplied to adder 22 so that a constant check sum is associated with each point in the program irrespective of the route by which that point was reached. For a loop, the sum of the memory read-outs along the loop and the correction value is zero.

Title: Carbothermic method for converting a reactive metal oxide to  metal or nitride form in a specific molten metal solvent
IPC: C01B21/076
Filed: 1971-01-18
Abstract: 1342991 Boron; silicon; metal nitrides; titanium hydride PARLEE ANDERSON CORP 18 Jan 1971 2258/71 Heading C1A [Also in Division C7] Metals, or non-metals such as boron and silicon, which are readily capable of reacting with nitrogen or carbon to form nitride or carbide are reduced from their oxides by a carbothermic method using carbon or carbon source material in excess of stoichiometric requirements, in a molten solvent at temperatures above 600‹ K., the carbon monoxide partial pressure over the reaction mixture being maintained below the equilibrium value for the reaction. The metal solvent is one which lowers the reactivity of the reduced product below that required for the formation of carbide and is capable of forming stable compounds with the reduced product. Tin may be used as solvent metal in the production of boron or silicon or copper in the production of boron. By maintaining a partial pressure of nitrogen over the reaction mixture the reduced metal or non- metal may be obtained as a pure nitride product which can be separated from the solvent metal. In this way nitrides of such metals as niobium, tantalum, plutonium, uranium, zirconium and hafnium. When the reaction mixture contains a mixture of metals, specific gravity differences between the nitrides formed may allow a separation to be effected, lighter nitrides floating on the solvent metal while heavier nitrides sink. Alternatively, where titanium is the reactive metal a hydrogen atmosphere may be used to form titanium hydride which floats on the solvent and may be skimmed off.
