Title: Improved means for regulating the dynamos used on motor road vehicles
IPC: B60R16/02
Filed: 1932-12-10
Abstract: 411,538. Charging and discharging batteries. LUCAS, Ltd., J., and LUCAS, 0., Great King Street, Birmingham. Dec. 10, 1932, No. 35093. [Class 38 (iv).] The engine-driven generator on a motor road vehicle has its output altered by actuation of a free-wheel device disconnecting the engine from the road wheels so that it gives a larger output when the vehicle is free-wheeling than when it is being driven by the engine. A resistance c in the excitation circuit of the dynamo, e.g. a three brush generator, is short-circuited by actuation of the vehicle free-wheeling device which operates on a switch d. Alternatively, the switch d may control an additional field winding which is energized when the free-wheel device is actuated.

Filed: 1934-12-07
Abstract: 448,861. Coking processes. OTTO & CO., GES., C., 9, Christstrasse, Bochum, Germany. Dec. 7, 1934, Nos. 35226, 35227, and 35229. Convention dates, May 14, 1934, May 22, 1934, and Aug. 6, 1934. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 8, 1935.] [Class 55 (i)] In coke ovens in which hollow spaces are made in the charge by mandrels, and gases are withdrawn from these ducts and from the space above the charge, means are provided for conducting distillates from these two sources into the same hydraulic main through regulable openings provided between a collecting channel in the oven cover, and the space above the charge. The channel, and the space above the charge, communicate independently of the openings with the same hydraulic main. In Fig. 1, vertical ducts 3 are made by mandrels inserted through passages 4 in the oven cover, and tubes 5 are inserted which open into a channel 6 communicating with the gas main 10 by an ascension pipe 9. Each channel 6, communicates with the ascension pipe through a duct controlled by a damper 8, a damper 13 controlling the flow from the space 12 to the ascension pipe. Gases pass from the space 12 to the channel 6, either through openings 15 in the tubes 5, or through annular spaces 4 adjusted by throttling members 17, so that the pressure in the space 12 is nearly atmospheric when considerable suction is being exerted on the tubes 5. In a modification, only every other duct 3 is fitted with a tube 5, the unoccupied passages 4 being throttled Scavenging gases may be forced through the charge if a high resistance exists between the gas collecting space and the ascension pipe, the gases escaping from the hot outer layers entering the ducts freely open to the gas collecting space, both these gases and the greater part of the external gases being drawn off through the tubes to the gas collecting channels. The external gas in this case serves as a scavenging gas, but other gases may be used and supplied. The Specification as open to inspection under Sect. 91, comprises also the use of other gases as shown in Figs. 5 and 6 (Cancelled). The gas is fed through a pipe 20 to channels 19 communicating with every other tube 5, and superposed by the collecting channels 6. The ducts 3 may open either into the gas collecting space, or may be connected by the tubes .5 with the collecting channels 6, dampers 8, 13, being suitably adjusted. This subjectmatter does not appear in the Specification as accepted.

Title: Field-effect transistor and method for making same
Inventor: JONES MORTON EDWARD
IPC: H01L29/00
Filed: 1956-11-19
Abstract: 816,740. Coating with metals. TEXAS INSTRUMENTS Inc. Nov. 19, 1956, No. 35317/56. Class 82(2) [Also in Group XXXVI] A field effect transistor is produced by depositing from the gaseous phase an acceptor (or donor) material over the whole surface of a grooved N tpe (or P type) wafer and then removing all the deposited material except that from the grooved region of the wafer protected by a peripheral band. The Figures show a wafer 10 of N type silicon or germanium having a groove 11. The wafer is heated to between 1000‹C. and 1200‹C. for 8 hours in an atmosphere of 2-5 per cent boron halide or hydride in an inert gas. Boron trichloride and decarborane (B 10  H 14 ) are given as examples, with helium. This results in deposition of boron on the wafer which converts the surface to P-type conductivity. A band of etch resistant material such as polystyrene is then put around that section of the wafer including groove 11, and an etching or sand blasting (e.g. with silica carbide) process applied to remove all the unprotected portion of the P-type layer. After removal of the polystyrene layer the field effect transistor is then provided with ohmic connections on end faces 25 and 26 to constitute source and drain electrodes, the P-region 13 constituting the gate electrode. An aluminium wire may be welded to the P-layer to provide the lead connection. Aluminium, gallium, indium or thallium may be utilized instead of boron. Reference has been directed by the Comptroller to Specification 782,662.

Title: Improvements in or relating to mainsí¬superposition electric central remote control installations
IPC: H02J13/00
Filed: 1956-11-23
Abstract: 840,037. Electric selective signalling systems. LANDIS & GYR A.G. Nov. 23, 1956 [Nov. 26, 1955], No. 35836/56. Class 40 (1). An electric cyclic remote control installation in which each control cycle comprises a number of control periods each associated with a particular switch being controlled and in which in each control period an impulse is transmitted either during the first half of the period or during the second half of the period to signal whether the associated switch should be closed or opened and to cause the switch to assume the signalled condition if its condition is not as signalled, is used in any cycle in which no switch has to change its condition to transmit additional data (such as an air-raid warning) by suppressing the impulses in two or more successive periods. As described, Fig. 3, a " start pulse " superimposed on the power lines N causes a synchronous motor S to start. This rotates a toothed wheel KR which, in turn, rotates a freely-mounted cam P. Each received impulse actuates a solenoid M and if an impulse occurs in each control period this prevents the cam P being rotated sufficiently far to close a contact p. If, however, pulses do not occur in two or more successive control periods the cam P closes the contact p to indicate the reception of additional data (e.g. to sound a siren). Specifications 594,361, 646,505, 667,842 and 795,954 are referred to.
