Title: Improvements in or relating to gas turbine engines and more particularly jet turbine engines
IPC: F02C7/236
Filed: 1954-07-12
Abstract: 761,182. Gas turbine Jet-propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 12, 1954 [July 15, 1953], No. 20343/54. Class 110 (3). [Also in Group XII] In a gas turbine engine, the combustion equipment is provided with flame stabilizing means constituted by a gaseous screen formed by a jet or jets of gas, for example air, issuing transversely to the flow of combustion gases through the equipment. The air supply for the screen is from an auxiliary compressor which supplies the air at a pressure greater than that supplied by the main engine compressor. The engine shown comprises an air compressor 1, turbine 5 and combustion equipment 3, the stabilizing screen being formed by jets of air issuing transversely through apertures 8, 8a in the hollow ring members 7, 7a. Fuel is supplied in an upstream direction through nozzle 4. Air is tapped from the main compressor discharge at 13 and is further compressed in the auxiliary centrifugal compressor 11 and passes by way of pipes 10 to the hollow ring members 7, 7a. Additional fuel may be supplied through an injector 4a into the air delivered by the auxiliary compressor. The auxiliary compressor is driven by a turbine 14 supplied with combustion gases tapped from the discharge of the combustion equipment 3, the exhaust from the turbine 14 passing through an auxiliary propulsion nozzle 17. The auxiliary compressor may alternatively be driven by the main turbine 5 by means of suitable gearing or it could be mounted on the main turbine-compressor shaft. The auxiliary turbine 14 may be supplied with gases from auxiliary combustion equipment supplied with air from the main compressor 1. Specifications 751,013, 751,098 and 761,167, [all in Group XII], are referred to.

Filed: 1943-12-07
Abstract: 576,063. Controllers. SHAW, D. Dec. 7, 1943, No. 20481. [Class 38 (iii)] Brake devices. In a braking system for an electrically-driven vehicle, a switch for effecting changeover from motoring " to magnetic braking is biassed to the braking position and pneumatically operated to the motoring position. Failure of the air supply or the elctrical supply causes the switch to move to the braking position. In Fig. 1 a " motoring braking " controller 1 is operated by rack and pinion 3 associated with pistons 6 and 7. The controller is biased to " braking " by spring 12 on piston 7 and is moved to "motoring" (power) by compressed air, controlled by a solenoid operated valve 10, on piston 6. A three-pole switch 1<1>, operated in a similar manner to the controller on the failure of air supply, substitutes for pneumatically-operated contactors to complete the braking circuit. A manual switch in the braking circuit is opened when it is desired to move the vehicle after failure of the air supply.

Title: Improvements in or relating to teleprinter exchange systems
IPC: H04L12/02
Filed: 1938-07-15
Abstract: 516,990. Telegraph exchange systems. STANDARD TELEPHONES & CABLES. Ltd., and HYDE, G. A. M. July 15, 1938, No. 21079. [Class 40 (iii)] Means such as short-circuiting contacts mc are provided to prevent the printing of undesired characters by the supervisory signals in start-stop teleprinter exchange systems. A clearing signal comprising a long space therefore has the effect of starting the teleprinter shaft; if thereafter the teleprinter is not in the stop position when the motor stops, a letter will be printed when the motor subsequently starts. Dialling impulses produce similar errors. According to the invention these are obviated by preventing the teleprinter magnet TRM from acquiring the marking condition until the teleprinter reaches the stop position. Thus, the motor M at a subscriber's station is started when polarity is put on the line either by the receipt of an incoming call or in response to an outgoing call ; in either case relays P and K pull up. According to the invention the connections shown in broken lines are added ; these include the contacts mc, which shortcircuit the receiving magnet TRM and dialling contacts ONS1 until the teleprinter, on the occurrence of a call, reaches the stop position, when the contacts mc are opened mechanically and the receiver magnet TRM pulls up and stops the teleprinter. The short-circuit is thereafter broken by the armature x2 of relay X, which holds on during-normal signalling. During dialling, however, the locking circuit of this relay is broken, and the receiver magnet TRM and relay X are short-circuited at the offnormal contacts ONS1 and ONS2 respectively ; thus the dial impulses are unable to operate the teleprinter. In a modification, Fig. 2 (not shown), the invention is applied to that described in Specification 498,428, in which the release signal comprises a long space which has a delayed action. Contacts mc, wr2 (not shown), operated respectively by the teleprinter and by a long space constituting a release signal, or part of a signal for calling in the exchange operator, disable the teleprinter receiving magnet after a long space until the teleprinter reaches the stop position. The contacts mc may be controlled by the resetting magnet of the teleprinter.
