Title: Improvements in or relating to oil bath gas filters
IPC: B01D46/24
Filed: 1949-03-07
Abstract: 660,387. Air cleaners. TRIGGS, W. W. (Air- Maze Corporation). Mar. 7, 1949. No. 6159/49. Class 8 (ii). In an air cleaner of the type having an oil bath 13, Fig. 1 contained in a bowl-shaped housing 10, the air entering the housing at opening 11 and being forced downwardly outside an annular skirt 21 through the bath 13, upwardly inside the skirt, and radially inwardly through a filter element 15 to a central outlet 16, oil globules are broken up and evenly distributed by filament means e.g., corrugated hardware cloth 26 of three meshes per inch located between the filter 15 and the skirt 21. A second oil breaking means comprises corrugated hardware cloth layers 28 Fig. 2, located between layers 27 of sheet screen material which forms the filter element 15. A baffle 24 prevents air by-passing the filter 15. In a modification splash resisting elements of corrugated hardware cloth are positioned on both sides of the assembly of filters and oil-breaking elements form the bottom thereof to a point above the normal oil level 14. In a further modification the corrugations of the outer hardware cloth are slightly flattened at the inner side to enable the remaining cloths and filter elements to be secured thereto to form a unit, and the outer corrugations are flattened to enable the unit to frictionally engage the skirt.

Title: Improvements in and relating to variable electric resistances
IPC: H01C10/02
Filed: 1927-03-05
Abstract: 290,767. Drysdale & Co., Ltd., and Drysdale, J. W. W. March 5, 1927. Controllers, liquid ; controllers, actuating.-In a liquid rheostat of the kind in which the level of the electrolyte is regulated by means of a circulating pump and overflow weirs a regulating valve operated by the device to be controlled by the current in the rheostat is interposed in the circuit of the pump. The invention is described in connection with a motor-driven pump for a boiler feed. The electrodes a are enclosed in narrow chambers d in a tank b. Cooling liquid is circulated through the spaces h between the chambers d. A pump p draws electrolyte from a reservoir m beneath the tank b and passes it through a valve s contralled by the discharge of the feed-pump to the chambers d, whence it overflows over adjustable weirs r to the reservoir m. The electrodes are so shaped that the resistance is a function of the liquid level suitable to the characteristics of the motor and pump and the desired regulation.

Title: Improvements in or relating to decoding equipment
Inventor: BARBER DONALD ROBERT
IPC: H03K17/82
Filed: 1959-02-23
Abstract: 850,565. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. Feb. 23, 1959, No. 6232/59. Class 40 (9). [Also in Group XL (c)] In a decoder for binary signal pulses applied simultaneously from a digit pulse source 24, Fig. 3, to windings 16, 17, 18, the signal pulses switch respective storage cores 9, 10, 11 and develop output pulses in selected windings 19, 20, 21 which are combined in a winding 13 associated with a hole 2 in a transfluxor 1, Fig. 1, the combined output reversing the saturation flux in a ring 7 of transfluxor material about hole 2 to a width substantially proportional to the combined output pulse magnitude, whereby the width of flux reversal controls the amplitude of pulses applied from a sample source 28 to a load 31 by way of windings 14, 15 both associated with a hole 3. The main transfluxor flux is initially established by a pulse in a winding 12 associated with hole 2, and since this flux is in the same direction through core portions 4 and 5 no coupling is present between winding 14 and 15. When, however, the saturation flux in the ring 7 is reversed, the width of reversal determines the degree of coupling between windings 14 and 15, and alternating sample pulses pass to the load circuit. The transfluxor and switched cores 9, 10, 11 are restored to their initial state by applying a further blocking pulse to winding 12. This pulse restores the reversed flux in ring 7 to its original direction, and as a consequence induces a resetting pulse in winding 13 for the switched cores. In a modification, the digit pulse source 24 is arranged to supply positive digit pulses followed by negative resetting pulses, in which case the restoration of switched cores 9, 10, 11 restores the transfluxor to its initial state, and the provision of winding 12 and blocking pulse source 22 is no longer required. Reference has been directed by the Comptroller to Specification 814,455.

[Class 40 (v)] The amplitude of deflecting currents or voltages in television transmitting or receiving apparatus is maintained constant by rectifying part of the output by rectifier 14, smoothing it by filter comprising resistance 15 and condenser 16 and supplying the derived voltage to the suppressor grid of the pentode valve 11 to the output circuit of which the deflecting coil 10 or the other deflecting means is connected. The voltage applied to the rectifier is controlled by potentiometer 12, 13 and the development of too large a negative voltage is prevented by biasing the rectifier from anode supply 25 through resistances 17, 18. When frame and line sources are to be compensated a rectifier associated with one of the valves may be used to produce control potentials which are applied to each of the valves for stabilization.

Abstract: 871,788. Automatic control systems for dynamo-electric machines. MACFARLANE ENGINEERING CO. Ltd., and MACFARLANE, W. I. March 3, 1959 [March 5, 1958], No. 7013/58. Class 38 (4). In a control system in which the field of a dynamo-electric machine is supplied by an exciter, and the field of the exciter is controlled by an amplifier, the power supply for the amplifier is obtained by rectifying the output of one or more auxiliary windings on the armature of one of the machines. In one embodiment, Fig. 3, the output voltage of an alternator 23 is controlled by a Zener diode bridge 22 which controls the field 18 of a cross-flux exciter through a transistor amplifier E. The transistor and field 18 are supplied from a rectifier 20 and auxiliary 3-phase winding 19 on the alternator. In a modification, Fig. 4 (not shown), the cross-flux exciter is replaced by an alternator with rotor mounted rectifiers, a second transistor amplifier stage is added, and the two stages are supplied from two rectifiers and auxiliary windings on the alternator. In a further modification, Fig. 5 (not shown), the output stage of the amplifier is duplicated to obtain a larger output current, and three auxiliary supplies are provided. In another embodiment, Fig. 6, the output voltage of a D.C. generator 31 is controlled by a Zener diode bridge 22, which controls the field 35 of an A.C. exciter 34 supplying the main generator field through rectifier 36. In this case the auxiliary winding which supplies the transistor amplifier 32 is on the armature of the A.C. exciter. In another modification, Fig. 7 (not shown) the voltage-sensitive bridge is replaced by a resistor in series with a Zener diode. It is stated that instead of voltage, the system could control current, power factor, or the speed of a D.C. motor (as measured by a tachometer generator); and that the transistors may be replaced by magnetic amplifiers.

Abstract: 660,579. Phase-changing networks. AUTOPHON AKT.-GES. March 9, 1948 [March 10, 1947], No. 7252/48. Class 40 (viii). [Also in Groups XXXV and XL (c)] Bridge circuits for effecting phase-modulation of an oscillatory voltage have a losscontaining oscillatory circuit in one arm of the bridge, the resonant frequency being variable by the signal. As shown, the input oscillation is applied across the diagonal a b of a bridge, of which one pair of arms comprise unequal fixed resistors or impedances R3, R4 and the other pair comprise a fixed resistor R and a variable loss-containing resonant circuit R2. The Specification shows with the aid of a vector diagram, Fig. 5 (not shown), that if the loss resistor R associated with the tuned circuit satisfies the condition R/R1=(R4-R3)/2R3, phase-modulated oscillations free of amplitude modulation can be taken off from the diagonal d e. The reactive components of the circuit R2 may be arranged in parallel or in series and one or both components may be adjustable by the modulating signal so that its reactance changes in sign as the signal voltage changes in sign. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 660,645, [Group XXXV]. It also indicates that a second variable resonant circuit and fixed resistor may be substituted for the fixed voltage divider R3, R4, Fig. 6 (Cancelled, not shown).
