Title: Improvements in or relating to hot fluid conveying apparatus
IPC: H02K3/44
Filed: 1959-11-04
Abstract: 926,187. Pump motors. M. HANY, T. HANY, and E. HANY - PFISTER, [trading as HANY & CIE]. Nov. 4, 1959 [Nov. 7, 1958], No. 37385/59. Class 35. [Also in Group XXVI] In a motor-driven pump for hot liquids the sealed motor casing 1, 2 is filled with insulating liquid and communicates with the pump chamber through a baffle 15 so that pumped liquid can enter and leave the motor casing to relieve pressure due to heating and cooling. The motor windings are spaced by inorganic material, e.g. glass fibre, the insulation being provided by the liquid filling the motor casing. This liquid may be the same as that pumped if this happens to be non-conducting. Sheetmetal screens 26 protect the stator windings from turbulence. The terminal box is sealed from the motor casing by terminal board 32. In a modification a small impeller adjacent the bearing 17 circulates liquid through a bore in the motor shaft to the ducts 18, 19. To prevent heat flow from the pump to the motor casing they are joined by an intermediate part 3 having a narrow neck 3a. Radiation from the pump body is prevented by an asbestos screen 7. The pump body is also covered by an insulating layer 8.

Title: Electrical Drive and Method of Operating Such Drive.
IPC: B66B1/30
Filed: 1967-08-15
Abstract: 1,198,524. Control of D.C. motors. WESTINGHOUSE ELECTRIC CORP. 15 Aug., 1967 [9 Sept., 1966], No. 37454/67. Heading H2J. [Also in Divisions G3 and H3] The generator field F of a Ward Leonard set driving a lift is energized at variable average magnitude and direction from an A.C. source T3 via valve means (silicon controlled rectifiers SCR1 . . . SCR4), the valve means for one direction being blocked when the field current is high in the opposite direction but unblocked when the current is below a predetermined low level. The object is to provide smooth stopping or reversal. There are two SCRs for each direction, energized from centre-tapped transformer winding S3, triggering being effected at variable phase angle by pulses from saturable transformers 1TP, 2TP (one for each direction) in response to the difference between a reference voltage which varies in a prescribed " pattern " and the voltage from a tachogenerator TG. Each transformer 1TP, 2TP (see Division H3B) has a control winding 101, 103 in series with the field F connected so that when the field current is large enough in one direction the transformer for the opposite direction is saturated so that no triggering pulses are applied to its associated SCRs. At currents below saturation level both sets of SCRs are triggered; a resistor R2 prevents short circuit. The pulses are produced by the discharge of capacitors C1, C2 into transformer primaries P1, P2, when the voltage on them is sufficient to switch on unijunction transistors TR5, TR6. Synchronism with the mains supply is achieved by applying the unsmoothed, rectified output of a transformer 1T1, limited by zener diodes Z1, Z2 across the bases of the unijunction transistors. The capacitors are charged at a rate dependent upon the conduction of transistors TR1, TR2 which in turn depends upon the speed error voltage. This is derived from a bridge network C5, C6, R6 . . . R10 to which the reference " pattern" voltage and the tachogenerator voltage are connected in series opposition, and also the generator output voltage which is in opposition to the error to provide a stabilizing effect. Temperature compensation for the transistor circuits is provided by two further transistors TR3, TR4. Suitable component values are given (Fig. 14, not shown) and constructional details of the saturable transformers (Fig. 15, not shown).

Abstract: 900,674. Controlling burners. RADIATION Ltd. Nov. 7, 1960 [Nov. 9, 1959], No. 37985/59. Class 75 (1). A fluid fuel burning appliance includes a thermocouple junction heated by a pilot burner to maintain in open position an electromagnetic fuel valve and a further thermocouple junction positioned so that, if the normal path of the combustion products becomes blocked, it becomes heated and its output then opposes that of the first junction to cause the electromagnetic fuel valve to close. The two junctions may be provided by a single or by two thermocouples. In an instantaneous water heater the second junction is mounted on a block of ceramic material mounted on the outside of a hollow vertical combustion chamber of rectangular section below which is disposed a gas burner and above which is mounted a heat-exchanger comprising parallel finned pipes. Blockage of the combustion chamber and heat-exchanger causes the flames to impinge on the second junction. The Provisional Specification states that the thermocouple may be replaced by a bimetal strip or a phial and bellows.

Title: Tunnel diode circuit
IPC: H03K19/10
Filed: 1961-10-27
Abstract: 946,500. Tunnel diode switching circuits. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 27, 1961 [Nov. 28, 1960], No. 38563/61. Heading H3T. A unidirectional circuit comprises a first tunnel diode T1, having a first input threshold level, coupled to a second tunnel diode T2 having a second, higher, input threshold level, the arrangement being such that a signal which is sufficient to switch T1 and hence T2 when applied to input terminal A, is insufficient to switch the diodes when applied to the output terminal B. As described, the two tunnel diodes T1, T2 are coupled together by a resistor Rc. Diode T1 is biased via resistor R1 to a point on the low voltage portion of the characteristic such that it can be switched to its high voltage state by application of an input current of " normal " amplitude applied at J1. Diode T2 is similarly biased via resistor R2, but to a point requiring an input of twice the " normal " amplitude to switch it. A " normal " input at B will therefore leave both diodes in their low voltage state and no output will be produced at terminal A. On the other hand, a " normal " input at A will switch diode T1, and if Rc is correctly chosen, will produce a sufficient input at J2 to switch T2 also, and produce an output at B. The unidirectional circuit described may be incorporated into logic circuits to eliminate the effects of spurious signals, Figs. 7A, 8A (not shown).

Title: Improvements in or relating to processes for making transistors
Inventor: STRULL GENE
IPC: H01L21/60
Filed: 1957-12-13
Abstract: Aluminium and silver are evaporated in vacuum on to semi-conductor plates held in a graphite boat fitted with heating means.  Aluminium is first evaporated alone, the boat (and hence the plates) being held at a temperature above the eutectic temperature of the semiconductor and the aluminium.  The evaporation of the silver is then commenced and proceeds while the evaporation of the aluminium continues.  The temperature of the plates is then lowered to 350 DEG C. and silver is deposited alone until sufficient has been deposited to enable a good solder contact to be made to it.  Evaporation takes place through a mask on to the plates, the evaporating materials and the mask being so arranged relative to the plates that the silver is deposited only within the areas covered by the aluminium.  The semiconductor plates may be of germanium, silicon, or compounds of the elements of Group III and V of the Periodic Table such as aluminium phosphide and aluminium antimomide.  Specification 839,081 is referred to.

Filed: 1975-09-24
Abstract: 1514556 Reducing interference between radio signals DECCA Ltd 6 Sept 1976 [24 Sept 1975] 39195/75 Heading H4L Interference between two FM signals, e.g. video and audio signals to be recorded on the same track of a disc, is reduced by amplifying the second signal at 8, and attenuating the first signal at 5 at least in the frequency region covered by the second signal, in dependence on a control signal derived by detecting the first signal in the said region. The circuit of Fig. I acts to maintain the level of the audio signal (42), Fig. 4 (not shown), 6 dB above that of the video signal (41), as the video sideband amplitude in the frequency region of the audio signal varies. This region of the video lower sideband is separated by a filter 6 and detected 7 to provide the control signal which is applied to amplitude modulator 8 and bandpass filter 5. The control may be non-linear via networks 9, 10 respectively. Bandpass filter 5 is centred on the video carrier frequency, 3À56 MHz, and produces variable attenuation of the sidebands, in response to the control voltage, by adding filtered and unfiltered components (V 2 , V 1  respectively), Fig. 2 (not shown).

Title: Cermet resistance element and material
IPC: C03C14/00
Filed: 1966-09-02
Abstract: A cermet resistance material for firing on to an electrically non-conductive base such as glass to form a resistance layer having a low temperature coefficient of resistivity, comprises a finely-divided mixture containing 50 to 95% by weight of glass and 5 to 50% by weight of an alloy of ruthenium and rhodium, the alloy preferably containing at least 10% by weight ruthenium.  The resistance material is made by mixing the resinates of the metals with finely-divided glass particles, heating the mixture to remove volatile and organic material and to decompose the metal compounds, and so produce a dry material consisting of very small glass particles coated with or mixed with extremely small particles of metal alloy. Resistance elements are made by mixing the dry material with a suitable liquid carrier such as 7% ethylhydroxyethyl cellulose, 93% octyl alcohol and applying the fluid composition to the base material by methods such as silk screening, stencilling or spraying, a coating of approximately 0.001 inch giving a resistivity of 30-10,000 ohms per square. Any glass composition may be used in the resistance material and several examples of such compositions are given.
