Title: An improved alternating current compensator bridge
IPC: G01R1/28
Filed: 1963-09-26
Abstract: 993,093. Voltage measurement. ARENCO ELECTRONICS A.B. Sept. 26, 1963 [Sept. 28, 1962], No. 38006/63. Heading G1U. [Also in Division G4] In apparatus for measuring an A.C. voltage, a complex compensation voltage is altered by means of two groups of decade switches, associated with the real and imaginary components thereof respectively, to minimise a difference voltage, adjustment of a decade switch being prevented until the nearest decade above has been adjusted. In the Figures, the A.C. voltage to be measured is applied at AB in series with the primary of a transformer T3, the secondary L12-L16 of a transformer T1, and the secondary L22-L25 of a transformer T2. Transformers T1, T2 are used for introducing the real and imaginary components respectively of the compensation voltage, the primaries L11, L21 thereof being applied with a reference A.C. voltage through an amplifier FS having 90 degrees phase shift and phase reversers 1,2 as shown. The resistances of the secondaries L12-L16, L22-L25 of transformers T1, T2 are controlled by decade switches 01-05, 06-09 respectively. The difference voltage is produced across the primary of transformer T3 and is supplied, via secondary L32, amplifier F1 and filter Fi to phase-sensitive detectors I2, I6 controlling decade switches 02, 06. Detectors I2, I6 are also respectively supplied with the real and imaginary components of the reference voltage. Considering detector I2 as typical, one of two relays R21, R22 is energized to supply stepping pulses from a pulse generator PG (at E in Fig. 2) via one of two lines G, H to the decade switch 02 to step it in a direction corresponding to the sign of the difference of the two inputs to detector I2, until this difference falls below a threshold level when the energized relay R21 or R22 is de-energized again. When this has happened to both detectors I2, I6, back contacts K5-K12 of the associated relays close to allow pulses from generator PG to reach detectors I3, I7. The output of filter Fi is also supplied as shown to the detectors I3-I5, I7-I9 through amplifiers (X10) F2, F3, F4. In this way, the pairs of decade switches 02, 06; 03, 07; 04, 08; 05, 09 are adjusted successively. Means are provided to step the appropriate adjacent decade switch by one step when a given decade switch steps from 0 to 9 or vice versa. Decade switch 01 can be stepped only between the positions 0 and 1, by switch 02. A digit indicator is associated with each decade switch 01-09, and latching means are provided to prevent the indicators moving outside their ranges. For blocking switch transients, the input to amplifier F1 is opened by a relay when any decade switch is being adjusted. Means for initial adjustment of the apparatus are described.

Abstract: 1,048,478. Transistor oscillating circuits. ROBERT BOSCH G.m.b.H. Sept. 27, 1963 [Sept. 29, 1963], No. 38098/63. Heading H3T. [Also in Division G4] A lamp flasher unit, such as a vehicle turn indicator unit, comprises an astable multivibrator containing two transistors T1, T2, the coupling from one transistor to the other including a third transistor T3 the input circuit of which has a bias resistor 20 which conducts the lamp current, and the output circuit of which includes a resistor 25 which controls the oscillator. The collectors of the transistors T2, T3 are coupled by a high value resistor 34, and upon initially closing switch 15 both transistors T1, T2 conduct, and the circuit does not oscillate. In one embodiment, Fig. 1, the collector circuit of transistor T2 includes a relay 24 which operates when T2 conducts, to connect the base of transistor T3 to the turn indicator switch 14. When this switch is operated to select either lamps 10 or 11 the lamp current flows in the base circuit of transistor T3, which includes a temperature sensitive resistor 22, switching it on, and allowing the circuit comprising transistors T1, T2 to start oscillating. Relay 24 then alternately releases and operates to flash the lamps. Should one of the lamps fail, the change in base current of the transistor T3 will change its conductivity, and thus modify the flashing rate of the circuit. The relay 24 may be replaced by a transistor switch in the emitter circuit of transistor T2, Fig. 2 (not shown), or by a switching circuit comprising a pair of crosscoupled transistors, Fig. 3 (not shown).

Abstract: 860,904. Moulding-processes. AMERICAN CAST IRON PIPE CO. Nov. 13, 1959, No. 38533/59. Class 83 (1). A metal centrifugal casting-mould is lined with a refractory by introducing an aqueous slurry of the refractory into the mould. which is rotated at a speed sufficient to distribute the slurry by centrifugal force over the inner surface of the mould and to compact the solid particles of the slurry against the mould wall to form a high-density lining while simultaneously causing the major portion of the water of the slurry to collect freely at the inner surface of the lining so that it may be removed, thereafter drying the lined mould to evaporate substantially all the remaining water. After removal of the free water, the mould lining may be washed by the introduction of fresh water. The slurry comprises a major proportion of silica sand and a minor proportion of silica-fines, and preferably a small amount of a gel-forming material or dispersing-agent such as western-bentonite or other clays, methyl-cellulose sodium-carboxymethylcellulose and hydroxyethylcellulose. Thickeners such as Glutrin (containing tannins and non-tannins), Cyoulac (derived from sulphite pulp process waste) and sodium-aluminate may also be added. When lining a vented mould, the slurry includes a proportion of larger particles which block the vents to prevent escape of the finer particles.

Abstract: 839,883. Axial-flow compressors; gas turbine plant. ROLLS-ROYCE Ltd. Nov. 27, 1957 [Dec. 19, 1956], No. 38779/56. Classes 110 (1) and 110(3). A gas turbine engine comprises a compressor, an abstracting means permitting cooling or sealing air to be abstracted from the compressor at a number of pressure locations therein, and control means including valving controlling abstraction of air from a selected one of the pressure locations while preventing abstraction at the other pressure locations. In the axialflow compressor shown, forming part of an aircraft gas turbine engine, air for cooling and sealing purposes is bled from a low-pressure stage at a tapping 18, which may be of the form described in Specification 712,051, and passes from an annular manifold 20 into the hollow rotor shaft 10 through ports 22. The air leaves the shaft through ports 27 and enters a chamber 28 to cool the shaft bearing 17 and seal it against the inward flow of hot air, leaving through a port 28a to provide a cooling flow between the shaft and the combustion equipment. When a cylindrical valve 25 is moved axially to a position in which a flange 25a closes the ports 22, ports 26 in the valve register with ports 23 in the shaft to permit air to be bled from a higher-pressure tapping 19. A piston 29 formed in the valve 25 and enclosed by an enlarged cylindrical portion 30 of the shaft 10 is exposed on one side to the relatively high pressure of a tapping 32, and is exposed on the other side to a pressure which, when a valve 34 is in the position shown, is that of an atmospheric pressure location 36. When the valve 34 is in its alternative position, the pressure communicated to the piston 29 is that at a high-pressure tapping 35, and the piston is moved leftwardly to bring the valve 25 into its alternative position. The valve 34 may be operated manually or automatically in accordance with the pressure within the shaft 10, or the ratio of the pressure in the air intake 14 to the static ambient pressure, or the temperature at the intake 14 or within the shaft. In an alternative embodiment, the two bleed tappings are located at the outer casing of the compressor and are connected by separate pipes to a selector valve similar to the valve 34, a single pipe leading from the selector valve to the chamber 28. Specification 622,181 also is referred to.
