Title: Improvements relating to remote control systems
IPC: B61L7/08
Filed: 1939-05-31
Abstract: 529,990. Selective signalling. - WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. May 31, 1939, No. 16000. Convention date, July 19,1938. [Class 40 (i)] In a remote control and supervisory system especially for train control from a central office; the control impulses and indicating impulses are sent over separate circuits and are alternately of opposite polarity the transmission of a signal over one circuit operating to prevent the transmission of a signal over the other circuit. At the control office a master relay OM is energized when a control code is to be transmitted and its contacts b, h connect the line circuit X1, X2 to the battery 9 and its contact j opens the indicating circuit so that the latter is put out of action. The transmitter relay OT operates pole-changing contacts b, d and the duration of the impulses thus applied to the line X1, X2 is controlled by the polarized relay OR operating a change-over switch a connected to the coding unit, Fig. 2. The starting key SK is closed on the unit corresponding to the station to be called, which is identified according to the code used by three long impulses and four short impulses acting upon stepping relays 01 ... 08, corresponding relays at the station being synchronously operated. The unit shown corresponds to code 234, the second, third, and fourth impulses being long. This coding is effected by controlling the reversal of the transmitting relay OT by a holding circuit or by a byepass circuit closed by slow-release relays OL1, OL2 to operate only when the stepping relays 02, 03, 04 pickup. When the remaining stepping relays pick up the reversal of the relay OT is not delayed and short impulses result. At the station corresponding to the code, the stepping relays 2, 3, 4, Fig. '3, are caused to respond by connecting thereto relays F, G, S. The control code is transmitted by a second operation of the stepping relays, a repeat relay OCR picking, up on the second operation of relay 01. Finally a delivery relay D picks up to operate the controlled devices at the station. When an indicating signal is sent from the station it is initiated by the picking up of a relay ST and the code is transmitted in a similar way to the control signal, the corresponding panel at the control office being selected by the connection to the stepping relays 02, 03, 04 of relays 2F, 23G, 234S. Finally, relay 16 picks up and de-energizes the relay M and restores the lines to normal. For distant stations one or more repeater stations may be interposed as shown in Fig. 1. The general operation of the system is similar to that described in Specification 415,787.

Abstract: 1,009,523. Electrical resistors. BUDD CO. April 30, 1962 [June 9, 1961], No. 16423/62. Heading H1S. An resistance, particularly a strain gauge or thermometric resistor is produced by electro polishing, through an insulating mask, a conducting foil to form a grid-like resistance element, the width of apertures in the mask is such that the regions of predominant attack of the electrolytic action, which are close to the edges of the mask, overlap. The insulating mask may be applied to the surface of a metallic foil, e.g. constantan, which has previously been bonded to a dielectric backing. The mask may be of photo etching material which is exposed to a light pattern and developed to produce a mask having a number of interleaved slots, Fig. 12. The foil is then connected in circuit with a stainless steel electrode in an electrolyte of 85% phosphoric acid. With a potential of 1 volt across the electrolyte electropolishing takes place until the material behind the slots is completely removed. The gauge is then trimmed along the dotted lines 121 to form the finished gauge. Chemical etching may be employed simultaneously with or subsequently to the electrolytic etching.

Title: Improvements in bi-fuel carburetters for internal combustion engines
IPC: F02M1/00
Filed: 1920-06-22
Abstract: 169,766. Dodson, E. June 22, 1920. Spray carburettors.-In a multi-fuel carburetting system for an engine in which variations of the power are controlled by the throttle, a fuel of low self-ignition temperature such as paraffin is used when the engine compression is low and a fuel of high self-ignition temperature such as alcohol is automatically brought into use when the engine compression is high. As shown in Fig. 1, the paraffin is supplied from a tank B to a submerged jet B<3>, air entering at B" forming an emulsion with the fuel. This is drawn into the air-supply pipe B<9> through the Venturi tube B<8> and the mixture enters the main air pipe A at a second Venturi A<2>. The alcohol is supplied through the pipe C, and is controlled by a valve, which may be interlinked with the throttle. A starting-fuel may be supplied through the pipe E, and additional fuel may be admitted through the pipe F when the throttle is fully open. At low compression, the paraffin mixture is drawn in; on increased suction the Venturi B<8> limits the supply of paraffin so that at high compression and full throttle practically only alcohol is being used. In a modification a three-way cock definitelv shuts off the paraffin mixture supply as the alcohol pipe is opened and vice-versa. In a modification, the paraffin emulsion is formed in a perforated tube B<16>, Fig. 2, the air thereto being admitted past the valve B<15>. Air is added to the emulsion in a Venturi tube B<18> and the mixture passes through the chamber B<20> and the Venturi tubes B<22>, A<7> to the main air passage way A. An exhaust jacket surrounds the paraffin-supply device in both modifications. Any fuel that is not vaporized when it enters the chamber B<10> is heated therein and drawn through the holes in the Venturi tube B<22>. The alcohol is supplied through the raised jet G<2>, the suction on the jet being controlled by a. secondary air inlet G<5>. The two fuels may be supplied by pumps, actuated through variable levers to control the quantity delivered. The means for varying the leverage is interconnected with the throttle valve.
