Filed: 1924-12-09
Abstract: 226,202. Patart, G. Dec. 11, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Producerrs. - Coal, wood and peat are distilled in externally heated retorts and the residue is passed to a gas producer in which air together with steam or distillation gases from the retorts are supplied to the charge. The retorts A and producer E are of an elongated rectangular or oval cross-section and the retorts are heated bv conduits D in which combustible gas such as the gas from the producer E is burnt, the fuel being supplied to the top of the retorts and discharged either as ashes or coke continuously or intermittently. Distillation gases are withdrawn through an outlet C and producer gas from an outlet F, and these gases may be collected separately or mixed together. The producer gas may be passed through the retorts and withdrawn with the distillates through the pipe C or the distillates may be passed into the producer and withdrawn through the outlet F. To obtain a gas rich in hydrogen the distillates from the retort may be passed into the producer through pipes such as L or H instead of or together with the steam.

Patent GB-632376-A (GB)
Title: Improvements in or relating to electric pulse systems
IPC: H04Q11/04
Filed: 1946-10-04
Abstract: 632,376. Automatic exchange apparatus. STANDARD TELEPHONES & CABLES, Ltd., and ROBERTS, W. L. Oct. 4, 1946, No. 29654. [Class 40 (iv)] [Also in Group XL (c)] The selection circuit for a pulse multiplex system as described in Specification 632,375 comprises an electronic device for selecting a time position in a cycle for the emission of a pulse in one or more steps from a reference time position, which may be the synchronizing pulse. A source C, Fig. 1, supplies a train of pulses, a, Fig. 2, -comprising timing pulses and larger amplitude synchronizing pulses. Normally, only the synchronizing pulses can pass the gate F, but, when a start signal from source B operates the gate, the timing pulses are also transmitted. Both types pass the phase shift gate C, curve f, and are applied to the synchronizing delay circuit H. Before the start signal operates, the synchronizing pulses are effective to operate circuit H which has an operating time only slightly shorter than the interval between them, curve H, so that, when the timing pulses commence they are ineffective. The circuit H feeds an output circuit producing pulses e which are also fed to a coincidence gating circuit E. Upon a phase shifting signal b being supplied from source A, the phase shift delay circuit D produces an output pulse c of slightly greater duration than the interval between two synchronizing pulses so that the coincidence mixer F emits a pulse d when pulse e is applied. The pulse d closes the gate circuit G to suppress the synchronizing pulse so that the circuit H cannot be operated by that pulse and is triggered by the first succeeding timing pulse. As a result the following output pulse e is delayed by one timing pulse, each input b causing a further delay. In the absence of further input pulses, the output pulses continue at the same intervals. When the start signal is removed, the timing pulses cease and the output pulses revert to synchronism with the synchronizing pulses.

Patent GB-427560-A (GB)
Title: Improvements in and relating to protective systems for electric circuits
IPC: H02H3/26
Filed: 1933-10-26
Abstract: 427,560. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and COE, R. T., Brandreth, Dunchurch Road, Overslade, Rugby. Oct. 26, 1933, No. 29745. [Class 38 (v)] The sensitivity and range of a protective relay R, the operative current I of which is supplied from a load current transformer C and is normally approximately balanced out by an auxiliary current 12 from a potential transformer P, is increased by varying the magnitude of the auxiliary current 12 from the potential transformer so that it is equal and substantially opposite in phase to I, and by injecting an adjustable phase-compensation current i3 into a third winding W on the current transformer. The current i3 is derivable either from the transformer P or from the line by a winding W2 on an auxiliary core, which is saturated so as to give constant voltage, and is adjustable in magnitude by means of impedance Z3. The range of the relay is variable by means of tappings on the primary, or as shown at T on the secondary, of transformer C, and an impedance Z2 enables the magnitude of the current 12 to be adjusted. Balance is obtained by means of an ammeter A and short-circuiting switches S1, S2, preferably a small current being allowed to traverse R in the operating direction. For byepassing heavy currents due to large changes in the load currents, a gas-discharge tube D shunts the relay. If the relay is to be responsive to load-current changes, the supply to P should be from a constant-voltage source in synchronism with the supply to the load, but if it is to be impedance-responsive, the load source should supply P. In the application of the invention to high-voltage cable testing, where the load current leads by 90‹ and masks the effect of a small fault current which is at unity power-factor, a fault constitutes a change in impedance and the transformer P is accordingly fed from the same source as the cable, the impedance Z2 is an adjustable condenser, and Z3 is an adjustable non-inductive resistance, Fig. 2 (not shown). The Specification also comprises an explanatory vector diagram, Fig. 3 (not shown). The Provisional Specification states also that the load current as obtained from the current transformer can be balanced against the potential transformer current through an impedance having the same nature as the load, the secondaries being in series for circulating current and the relay being connected so as to take the out-of-balance current caused by change in load-impedance.

Filed: 1946-10-05
Abstract: 617,547. Pressure gauges. KELVIN, BOTTOMLEY, & BAIRD, Ltd., and Mc- ALPINE, G. Oct. 5, 1946, No. 29779. [Class 106 (ii)] An indicating device for an aneroid barometer comprising an electric switch operated by a capsule to signal variations from the ambient pressure at one instant and electromagnetic means for rendering the switch sensitive to variations from the ambient pressure at another instant. A contact 4 carried by a bar 10 co-operates with one or other of two contacts 2 carried by capsules 1 to give a signal appropriate to a rise or a fall of pressure. The bar 10 is fixed to an armature 5 held firmly by an electromagnet 7 when energized. When the electromagnet 7 is de-energized its residual magnetism balances the weight of the armature, guides being provided to prevent the latter from falling, and any change in pressure will move the contact 4 through one of the contacts 2 until it is desired to hold it firm again by energizing the electromagnet 7. When used to indicate the height of an aircraft, the closing of the contacts upon a variation in altitude may actuate devices for automatically adjusting flight to maintain a constant altitude.
