Abstract: 1,265,894. Inorganic fibres. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 27 April, 1970 [6 May, 1969], No. 23174/69. Heading C1A. Inorganic fibres of e.g. Al 2 O 3 , ZrO 2 , ZrO 2 /CaO and Al 2 O 3 /CoO are produced by forming a viscous aqueous sol, spray drying the sol under conditions such that gel fibres are formed and calcining the gel fibres. The sol should not be thixotropic and it is preferred that the viscosity of the sol should be in excess of 500 cP at 25 C.; this may be achieved in a varietyof ways e.g. by controlling the concentration of the sol, controlling the anion to metal ratio of the sol, using a viscous additive or by means of heat treatment of the sol. The spray drier may be one in which the spraying is effected by means of a high speed atomizer disc, preferably one which can rotate at speeds in excess of 35,000 r.p.m. Calcination is conveniently carried out at temperatures in the range 700-1000 C. The diameter of the fibres may be controlled by regulating the concentration of the sol. Carbide fibres may be produced by forming a sol containing a carbon dispersion and calcining in a suitable atmosphere e.g. carbon monoxide. Nitride fibres may also be produced by calcining the sol. in a nitriding atmosphere. The fibres may be coloured by the addition of transition metal salts to the sol. In some cases the sol to be coloured also contains a silica sol and is stabilized by the presence of a few per cent of chloride or fluoride ions.

Abstract: 1,265,963. Automatic control of gas turbines. SMITHS INDUSTRIES Ltd. March 28, 1969 [April 5, 1968], No.16376/68. Heading G3R. [Also in Division G1]  In a gas-turbine engine fuel-control system, fuel supply is regulated in dependence upon an operational temperature of the engine, e.g. outlet temperature, inlet temperature or an intermediate stage temperature, and also upon another operational parameter, e.g. engine gas pressure, engine inlet temperature, engine speed, engine thrust, Mach number, or airframe skin-temperature. As shown, a signal derived from thermocouples 6 representing engine outlet temperature is applied to a bridge circuit 9 having a threshold set by a control 7 and when this threshold is exceeded the bridge output is applied to a regulator 3 to reduce the temperature to the desired value independent of the manual throttle setting 1. A signal representing the ratio of the exhaust to inlet gaspressure is derived from a transducer 12, e.g. as described in British Patent Specification No. 774,047, and is applied to a synchro control transformer 21 which produces an output representing the difference between the actual pressure ratio and the desired pressure ratio set by a control 22. This signal is applied to the threshold of the bridge circuit via an integrator and a switch 27. Alternatively, the signal may be combined with the temperature dependent signal. The regulator 3 may be replaced by a solenoid operable valve in the fuel supply line of the engine.

Abstract: 1297108 Casting machines DOW CHEMICAL CO 7 May 1970 [14 May 1969] 22054/70 Heading B3F [Also in Divisions B5 and G1] A die-casting machine has channels 18 and 24 in the die through which a liquid coolant flows, and at least two temperature sensors, e.g. thermocouples or thermistors, one 34 being located in the die in the zone of highest temperature and one 36 in the zone of lowest temperature. The temperature sensors are connected to a control unit 38 on which upper and lower limits for the casting temperature of the dies are set. If the temperature measured by one of the sensors falls outside these limits an indicator light 60 or 64 lights up and the casting cycle rate is adjusted to restore the die temperature to within the set limits. An automatic controller may be used to maintain the temperature within the desired range. When casting magnesium alloys the die temperature is maintained between 286 C. and 280 C. The flow of coolant is controlled by manually operated valves 22, 28 and 32 and by an automatically operated solenoid valve 30 which shuts when the casting cycle rate slows down too much or stops.

One bed adsorbs whilst the other is being desorbed and repressurised. As shown gas is supplied via line 18a or 18b to the bed 14 or 16 on adsorption containing a 5 zeolite sieve. Purified gas emerges via lines 20a or 20b and 20 upon desorption a metered amount of purified gas is passed as a purge via thin diameter lines 30, and 24a or 24b. Water pump jet 36 produces an initial rough vacuum of 176 mm Hg and a booster lobe pump 38 is automatically switched on at a preset level to enable a finer vacuum to be attained, i.e. 100 mm Hg. Impurities desorped are either vented or drained from a separating chamber 40 via lines 56, 70 respectively. The desorbed bed is repressurised by opening valve 34 in wider diameter line 26. The water pump Fig. 2 (not shown) incorporates a centrifugal pump and venturi tube.

Filed: 1999-06-21
Abstract: An apparatus for producing orthohydrogen and/or parahydrogen. The apparatus includes a container holding water and at least one pair of closely-spaced electrodes arranged within the container and submerged in the water. A first power supply provides a particular first pulsed signal to the electrodes. A coil may also be arranged within the container and submerged in the water if the production of parahydrogen is also required. A second power supply provides a second pulsed signal to the coil through a switch to apply energy to the water. When the second power supply is disconnected from the coil by the switch and only the electrodes receive a pulsed signal, then orthohydrogen can be produced. When the second power supply is connected to the coil and both the electrodes and coil receive pulsed signals, then the first and second pulsed signals can be controlled to produce parahydrogen. The container is self-pressurized and the water within the container requires no chemical catalyst to efficiently produce the orthohydrogen and/or parahydrogen. Heat is not generated, and bubbles do not form on the electrodes.
