Filed: 1974-06-04
Abstract: 1466583 Detecting hot spots photo-electrically SVENSKA ROTOR MASKINER AB 4 June 1974 [4 June 1973] 24691/74 Heading G1A Hot spots, such as 34, in a heat exchanger 18 are detected by a line of infrared detectors 24. The heat exchanger matrix is heated by a flow of hot gases entering at 14 and is liable to build-up of deposits of unburned combustion products, which may become dangerously expothermic.

Title: Voltage regulators
IPC: H02J7/14
Filed: 1970-05-22
Abstract: 1313175 Automatic voltage control ROBERT BOSCH GmbH 22 May 1970 [23 May 1969] 24852/70 Heading G3R [Also in Division H2] In a voltage regulator for regulating a D. C. voltage produced by rectifying an A.C. voltage by means of controllable rectifiers 21, 22, firing pulses are fed to the latter sequentially by a pulse separator 25 receiving high frequency pulses from a multi-vibrator 23 which is controlled by a regulating circuit 24 in dependence upon the magnitude of the D.C. voltage. If the voltage of a battery 15 drops, a transistor 27 becomes non-conductive thereby unblocking transistors 38, 39 in multi-vibrator 23. A pulse train is fed via transformer primary 44 to oppositely-poled secondaries 55, 56, and through diodes 59, 65 to the control electrodes of rectifiers 21, 22. When the D.C. voltage reaches a certain value, Zener diode 28 and transistor 27 conduct and block the vibrator 23, thereby stopping the pulse train. In a 3-phase arrangement, Fig. 3 (not shown), only positive pulses are produced and there are passed to a ring counter (84) for splitting into 3 pulse trains applied sequentially to transformers (81-83) to which the control electrodes of the rectifiers are connected.

Spin-stabilized rocket projectile has a portion (adversely effected by spin) surrounded by an annular combustion chamber located such that the centres of gravity of the portion and chamber coincide and that the ratio of the axial moment of inertia to the transverse moment of inertia lies between 0À4 and 1À5. A hollow charge 1 (adversely effected by spin) is surrounded by a combustion chamber 2 holding a propellant 3 and having nozzles 4, arranged peripherally around the rear of the chamber, which are inclined slightly to produce spin; while a ring 5 of iron, lead, copper or other high density material is arranged within the chamber 2. The centres of gravity of the chamber 2, charge 1 and ring 5 coincide at S. The dimensions of the various parts are chosen so that the moments of inertia have a ratio as stated above. One modification shows a projectile having separate propellants for launching and cruising arranged coaxially with the hollow charge, and another shows a launching unit and a ram-jet propulsion unit arranged coaxially with the charge.

Title: Improvements in automatic train control systems
IPC: B61L3/12
Filed: 1920-09-02
Abstract: 174,669. Howe, W. K. Sept. 2, 1920. Valves controlled by pilot or relay valves.-For automatic control of the brakes of a train from the track the driver's valve E is connected looselv to a piston 12 which is moved to the right of Fig. 2 by air pressure admitted through the differential piston valve F and the electropneumatic valve EPV when the magnet 33 is momentarily de-energized. The valve EPV is normally kept closed by the magnet 33, but when this is deenergized the air pressure in the pipe 28 acts on a large valve surface and the valve can only be re-closed by the energized magnet when the air pressure in the timing-reservoir 27 has fallen to a predetermined value. The piston 12 is moved up to the stops 14, and by means of the adjustable nuts 13 on the piston rod moves the valve E to service position, but the driver is able to hold the valve against such operation if he is aware of the operation of the apparatus. When the brake pipe pressure is reduced the piston 23, subjected on one side to main reservoir pressure from pipe 25 and on the other to brake pipe pressure from pipe 24 is moved to the right of the drawing and connects the reservoir 27 to the right end of the cylinder D, and the piston 17 then replaces the driver's valve E to lap position. Leakage ports 15, 20 on the cylinder D allow escape of pressure from the cylinder 27, and in connection with the smaller inward control valve 26 determine the time interval before the valve EPV is re-set automatically. If the driver, just before the de-energization of the magnet 33, applies the brakes and releases them before the lapse of this time interval, an automatic application is made since the piston 23 is restored when the brake pipe pressure is increased and the valve EPV is still open.
