Title: Sintered body mainly consisting of molybdenum disilicide
IPC: C04B35/58
Filed: 1957-05-02
Abstract: A sintered material e.g. for use as a resistor comprises a substantial proportion of molybdenum disilicide with 5-40% by volume of silica glass fibres as reinforcement.  It may also contain one or more disilicides of titanium, tantalum or zirconium, or oxides or silicon carbide.  The silica glass fibres are less than 0,08 inch long and between 0,00004 inch and 0,00079 inch thick.  The material is pressed, extruded or otherwise shaped to the desired form e.g. a rod or tube and sintered first in a hydrogen atmosphere up to 1200 DEG C. and then slowly in air up to 1500-1600 DEG C.  The mixture of silica glass fibres with molybdenum disilicide is mixed with a grinding liquid in a ball mill without balls to a grain size of 5m the dried, mixed with plasticisers and lubricants and subjected to cold pressing or hot extrusion.  In sintering, molybdenum ions enter the silica above 1200 DEG C. 10,000 grams of molybdenum disilicide, 2000 grams of tantalum disilicide and 1000 grams of silicon carbide are ground in ball mills with benzene as grinding liquid to grains of 0,0002 inch. 1500 grams of silica glass is added in batches, and after drying, 500 grams of bentonite in water is added, the mass being kneaded to make it plastic.  A mass of 850 grams molybdenum disilicide, 100 grams of titanium disilicide and 50 grams of zirconium oxide with 70 grams of silica glass wool is pressed into square resistance heating rods in a steel mill and sintered.

Abstract: 1351703 Colour television RCA CORPORATION 13 May 1971 [15 May 1970] 14769/71 Heading H4F Apparatus for stabilizing the biasing point of an amplifier circuit, such as a matrixing transistor 80 (81 or 82) in a colour television receiver in which a chrominance signal is applied to its base and luminance signal from transistor 70 (which also forms part of the amplifier circuit) is applied to its emitter, to maintain the voltage level at its output (collector electrode) constant, comprises a bias transistor 103 with its base coupled via capacitor 102 to its collector, which is coupled to the emitter of the transistor 80, via capacitor 110 to a source of positive horizontal blanking pulses, and via diode 107 to the output collector electrode of amplifying transistor 80. The horizontal blanking pulses cause both the diode 107 and transistor 103 to conduct, the diode 107 conducting in accordance with the potential on the output collector of transistor 80 and causing capacitor 110 to charge accordingly. The resulting voltage on capacitor 110 determines the voltage across capacitor 102. Capacitor 102 operates to maintain conduction of transistor 103 relatively constant and thus causes the transistor 103 to shunt current from transistor 80 via the emitter of transistor 80 to maintain the collector of transistor 80 at a fixed voltage level. A frequency peaking network is shown in the luminance channel which comprises a transistor 21 with an adjustable resistor 33 coupled to its output collector electrode. Capacitor 36 is coupled between the slider of the resistor 33 and earth, and two resonant circuits 40-42 and 50-52 are coupled in parallel between the junction 35 (of the slider of the resistor 33 and the capacitor 36) and the emitter of transistor 21. A second variable resistor 43 is connected in series with the resonant circuit 50-52 and comprises a contrast control. When the slider of resistor 33 is adjacent the collector of transistor 21, capacitor 36 shunts the collector of transistor 21 and reduces the high frequency response thereof. When the slider is coupled to the supply voltage source Vc the resonant circuits are grounded for A.C. signals. A capacitor 45 is coupled between one end of resistor 43 and the adjustable slider and when the slider is adjacent the emitter of transistor 21 the resistor 43 is by-passed and transistor 21 is operated at maximum gain while maintaining the peaking constant. Horizontal blanking pulses are fed via a diode 56, and vertical blanking pulses are fed via a diode 62, to the collector of transistor 21, a diode 64 being connected across peaking resistor 33. Thus during the horizontal and vertical blanking pulses the voltage at the collector of transistor 21 tends to increase towards Vc, the peaking resistor 33 being by-passed. The slider of resistor 78 comprises a brightness control for the luminance channel.

Title: New or improved switch arrangement for actuating signalling devices on motor vehicles
IPC: G08B5/36
Filed: 1952-06-12
Abstract: 713,228. Audible and like signalling-apparatus. PETRI, F. June 12, 1952 [Aug. 14, 1951], No. 14798/52. Class 118 (2). An electrical switch arrangement for actuating signalling devices on a motor vehicle comprises the usual contacts for actuating one device, say the horn, and in addition thereto, further contacts serving for the actuation of a further device, the two sets of contacts being electrically connected with the interposition of a delaying means which causes the second device to be sounded automatically after a predetermined duration of operation of the one device and to continue being sounded so long as the first device contacts are closed. On closing contacts 11, which may be the normal horn button, the circuit of a horn Sl is completed and, in parallel therewith, the circuit of a thermal delaying device 1 which comprises a wire 6 under tension of a leaf spring 9 and a series resistance 7. The wire 6 normally holds a strip 4 clear of contact 3 but current in wire 6 heats it and causes elongation which eventually allows strip 4 to complete the circuit to contact 3 and energise a second horn or other additional signalling device S2. A screw is provided to adjust the tension of the leaf spring 9 and thereby vary the delay between the signals, for example, from 0.5 to 2 seconds. The delaying device may alternatively comprise a bi-metal strip or magnetic relay. The circuit of the first signalling device may be broken when that of the second is completed. The delaying means may be arranged to switch off the first signalling device as soon as the second is switched on.
