IPC: C06B47/14
Filed: 1972-03-08
Abstract: 1364772 Explosive compositions DYNO INDUSTRIER AS 8 March 1972 [10 March 1971] 10775/72 Heading C1D A water-bearing explosive composition is prepared by mixing a thickened solution or dispersion of the oxidizing component with a viscous or thickened solution or dispersion of the fuel, the two solutions or dispersions having approximately the same consistency. Mixing may be carried out using gear pumps of controlled relative speed to pump one liquid through a large number of openings into a stream of the other liquid. In examples, dispersions containing ammonium nitrate, calcium nitrate, sodium nitrate, urea, water, ethylene glycol, tapioca starch, and guar gum are mixed with dispersions containing ethylene glycol, flake aluminium, powdered asphalt, and a thickening agent (evaporated sulphite liquor or polyacrylate). Sodium dichromate solution containing disodium hydrogen phosphate may be added during mixing to assist gelling. Other ingredients referred to are molasses, TNT, coal, pitch, peat, cork, wood, bark, Mg, Si, B, and xanthan gum. Agents may be added to stabilize dispersed air in the final composition.

Title: Temperature compensator in multivibrator circuits
Inventor: RYWAK JOHN
IPC: H03K3/281
Filed: 1965-03-15
Abstract: 1,086,575. Stabilizing multivibrators. NORTHERN ELECTRIC CO. Ltd. March 15, 1965, No. 10843/65. Heading H3T. The period of a multivibrator is stabilized by a pair of diodes connected in series to produce a temperature-sensitive compensating voltage. As shown, diodes D5 and D6 provide a temperature-dependent voltage which compensates for the variations in the voltage to which the timing capacitors charge due to variations with temperature of the voltage drop across the base-emitter diodes and the isolating diodes D3. The compensating diodes may alternatively be placed at points B and C in series with the collector paths or may be supplemented by additional diodes at these points in which case, as in Figs. 4 and 5 (not shown), diodes D5 and D6 may be replaced by the combination of an emitter-base diode (Q3) and a further series diode (D7). The compensating diodes may alternatively be inserted in series with discharge resistor or resistors R5 and R6 (see D14 and D15), Figs. 7, 9 and 10 (not shown) and additional isolating diodes (D11, D11<SP>1</SP>) may be connected between the collectors and the timing capacitors. Oscillation may be interrupted by a shunting transistor (Q14, Fig. 10). Diode temperature stabilizers may also be applied to monostable multivibrators (see D14, D15, Figs. 7 and 9, not shown) the circuit of Fig. 9 including a transistor (Q13) which when rendered conducting discharges the timing capacitor C1 so that if pulses are applied to the discharging transistor the circuit remains in its unstable state unless the gap between the pulses exceeds the timing interval. Reference has been directed by the Comptroller to Specifccation 938,946.

IPC: B64C15/02
Filed: 1951-05-10
Abstract: 750,601. Jet propulsion nozzles. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. May 10, 1951 [June 16, 1950], No. 11054/51. Class 110(3) [Also in Group XXXIII] In a jet propulsion engine having an air compressor for example a jet turbine engine, a device is provided for deflecting the jet stream towards flow guiding means arranged laterally of the jet stream. Auxiliary nozzle means open into the main jet stream opposite the flow guiding means and are adapted to form a screen-like fluid obstacle when supplied with air under pressure from the engine compressor which causes the main jet stream to be deflected towards the flow guiding means. In Fig. 2 the downstream portion 49 of the jet nozzle is movable so that when in the extended position shown in the upper half of the Figure an annular orifice 48 is formed. A hollow faired member 45 is supported at the centre of the jet nozzle by struts 46 and when it is desired to deflect the jet stream, air is supplied from the engine compressor through the pipe 46a and issues through the nozzle 47 in the member 45 and causes the jet stream to be deflected through the lateral orifice 48. In Fig. 4 a hollow faired member 53 extends across the downstream end of the jet nozzle which is of rectangular section and air under pressure issues through the slots 54. Flap members 55 are pivotally mounted at the downstream end of the jet nozzle and when in the operative position shown at the upper half of Fig. 4 form a curved path for the deflected jet stream. The deflection of the jet stream may be assisted by applying suction to the slots 58 in the pivoted flaps. In Fig. 8 a hollow faired member 53 is mounted vertically in the jet nozzle and the deflected jet stream issues through lateral orifices 13, 13a which are provided with curved deflector vanes 44. In other embodiments retractable solid deflector members are provided in addition and cause deflection of the jet stream if the deflection caused by the jet of air under pressure is insufficient. Specifications 691,302, 691, 984 [Group XXXIII] and 750, 623 are referred to.

Abstract: 1464772 Automatic control of temperature MAXITROL CO 13 March 1974 [14 March 1973] 11241/74 Heading G3R A system for controlling the temperature of make-up air supplied to a building 12 comprises a building air temperature sensor 44, and a probe 42 located in a duct 38 downstream of a gas burner 26 to measure make-up air discharge temperature, the sensors being connected to a device 66d for setting the desired building air temperature and to an electronic control unit 40 containing devices for setting maximum and minimum make-up air discharge temperatures, and the unit 40 producing a control signal to a modulating valve 14 to control the supply of gas to the burner in accordance with any differential between the actual and desired building air temperatures but not allowing the make-up air discharge temperature to rise or fall beyond its set limits. The sensor 44 includes a thermistor 72, Fig. 3, connected in series with the setter 66d in one arm of a voltage divider which is connected across points B, C to determine the base voltage of a transistor 76. This transistor is in series with a transistor 78 which is normally saturated but which is progressively biased to cut off as the temperature sensed by a duct outlet maximum temperature sensor 70 in the probe 42 exceeds that set by corresponding potentiometer 64. The pair of transistors 76, 78 is shunted by a transistor 74 the base voltage of which is determined by duct outlet minimum temperature sensor 68 and corresponding setter 62. The transistor 74 is normally cut off but takes over control if its bias to conduct becomes greater than that of the transistor 76, thus determining the duct outlet minimum temperature. The resultant current is used to control the firing of a thyristor 132 in series with the control coil 16c of a pilot gas valve 16. The latter has its outlet 16b connected to a passage 14d of the main valve 14 and thus controls the latter.

Abstract: 1518647 Multiplexing arrangements for data transmission SIEMENS AG 18 March 1977 [23 March 1976] 11638/77 Heading H4P An arrangement for controlling multiplex operation between a first unit Z and a plurality of second units K to Kn comprises an input multiplexer EM which serves to transmit, via lines EL, input parameters from the units K1 to Kn to the unit Z; an output multiplexer AM which serves to transmit, via lines AL, output parameters from the unit Z to the units K I to Kn; and a drive circuit (Fig. 5, not shown) for controlling the multiplexers EM and AM in such a way that the input and output of information respectively to and from the first unit Z can overlap in respect of different ones of the second units K. Thus, following the selection by the input multiplexer EM of a first one of the second units, the unit Z outputs information to this first one by way of the output multiplexer AM, and before the action of multiplexer AM is complete, the input information from a second one of the units K can be connected to the unit Z. Thus, the unit Z can commence its activity in respect of the second unit K immediately on completion of its operation in respect of the first unit K, whereby waiting times which can arise in the unit Z are reduced.
