Abstract: 1,056,753. Pulse radar. SOC. ALSACIENNE DE CONSTRUCTIONS ATOMIQUES, DE TELECOMMUNICATIONS ET ELECTRONIQUE, EN ABREGE "ALCATEL." Oct. 5, 1963 [Oct. 16, 1962], No. 40626/63. Heading H4D. In a pulse radar a short pulse (e.g. 0À2 Ás.) of carrier wave is applied to two phase-shift networks, both having a group propagation time linear with frequency but that of one being of opposite slope to that of the other, the ensuing long (e.g. 200 Ás.) frequency-modulated pulses are gated such that an initial portion of one long pulse and a final portion of the other long pulse are amplified and radiated (the portions being e.g. each 10 Ás. long), the echo pulses are fed to respective phase-shift networks such that they are time-compressed, and the time interval between the compressed pulses is measured to give target radial velocity. The phase-shift networks are of the resistance-capacitance type.

Title: Improved fuel injection system for an internal combustion engine
IPC: F02D9/00
Filed: 1958-12-23
Abstract: 843,081. Fuel injection systems. GENERAL MOTORS CORPORATION. Dec. 23, 1958 [March 5, 1958], No. 41464/58. Class 7(3). In a fuel injection system for an internalcombustion engine, in operation, fuel is continuously projected into each cylinder intake passage by a nozzle and the jet of each nozzle projects the fuel through a chamber containing air under pressure and then through an orifice which is so restricted as to minimise escape of air from the chamber into the engine. Plenum chamber 18 is connected by a plurality of intake passages 20 to the cylinders 22 of the engine. An injector pump 32 is located in the fuel reservoir 26 and supplies fuel under pressure to a fuel metering valve 44. The valve 44 controls the amount of fuel supplied to the engine, the fuel flowing through a conduit 36 a distributer 38 and individual fuel conduits 40 to nozzles disposed in each of the intake passages 20. The position of the valve 44 is controlled by the pressure drop caused by air flow through the venturi 14. Thus the pressure at the venturi throat acts on one side of a diaphragm 52 and controls the valve 44. The nozzles (Fig. 3) 42 have each an inlet portion 60 in which the end of a fuel conduit 40 is fixed; a nozzle jet 62; an air chamber 68; and a restricted orifice 64. The jet 62 projects a stream of fuel through the chamber 68 the restricted orifice 64 and a shroud-like part 72, into an intake passage 20. A plurality of radiating passages 66 connect the chamber 68 with the hollow interior of a block of heat insulation material in which a number of nozzles are mounted. The hollow interior of the block communicates with an air manifold 70 which is connected to an air compressor 74 (Fig. 2) and the pressure in the chamber 68 is therefore the same as that in the manifold. The air manifold 70 is connected by a conduit 92 to the reservoir 26. The invention can readily be embodied in existing fuel injection systems without altering their metering arrangements by exposing the fuel upstream of an injector pump to air at the same pressure as that in the chamber or chambers.

Abstract: 1482967 Cooling superconductors SIEMENS AG 27 Sept 1974 [24 Oct 1973] 42204/74 Heading H1A [Also in Division H2] An electric cable has concentric inner and outer superconductors 2, 3 connected at the end of the cable to inner and outer normal conductors 7, 8 of a cable terminal portion A, there being a first passage c, d common to the inner conductors and a second passage a, b common to the outer conductors for receiving coolant at a position remote from the terminal portion. Where a terminal portion is provided at the other end of the cable, the inlet is remote from both said portions. The superconductors are preferably made from niobium stabilized on a normally conducting metal, e.g. Al, Cu, so as to have a constant length irrespective of temperature, and with super critical Helium at pressures greater than 2À3 bar as the coolant. With other superconductors, hydrogen may be used as the coolant. At the inlet a spiral duct 18 may be used to overcome the potential drop across the insulation 4. The flow from the superconductors to the normal conductors is preferably controlled by throttle valves 20 to give a constant temperature across the boundary. The flow rate is controlled by valves 27, 28 in the return lines 24, 25 in response to signals from temperature sensors 33, 34. Leakage lines for the coolant, and indirect signal transmission from sensor 33 are required since the inner conductors are at high potential. The fluid held back by throttle valves 20 passes along lines 30 past radiation shields 40 to a coolant station 12 before being recycled. Again a high voltage transmission element (e.g. plastics line or plastics labyrinth) is needed for the coolant from the inner passage. For long cables a plurality of cooling stations 12 are provided along with an associated cooling circuit, arranged symmetrically along the cable to provide continuity of temperature at the circuit boundaries (Fig. 2, not shown).
