Patent GB-915763-A (GB)
Abstract: 915,763. Cathode-ray oscilloscopes. AMERICAN MACHINE & FOUNDRY CO. April 1, 1959 [April 4, 1958], No. 11119/59. Class 40 (7). [Also in Group XXXVIII] To determine the phase position of the peak of an A.C. voltage derived from a vibration pick-up L, R measuring the unbalance of a rotor T driven by a motor M, the voltage is fed to the vertical plates of an oscilloscope 30, whose time base is synchronized with the signal voltage and can be varied to display the whole or half or quarter of a cycle. The particular part of the cycle displayed is determined by utilizing four pulses in quadrature in each cycle produced by a synchronous generator P, a switch S3 selecting the particular pulse to initiate the part cycle time sweep which allows the peak to be displayed. A further synchronous pulse generator X produces 60 cycles per revolution, which are fed through a pulse shaper circuit 31 to the oscilloscope intensity grid circuit to produce fifteen marker pulses for each quarter-cycle, spaced 6 degrees apart, enabling the phase position of the peak of the A.C. signal voltage to be established.

Title: Refrigerant recovery systems
Inventor: PAXTON RUSSELL
IPC: F25B45/00
Filed: 1992-02-12
Abstract: A one-pass refrigerant recovery and purification system removes refrigerant from a refrigeration unit, filters and purifies it and condenses and stores the refrigerant in its liquid state for reuse. A collection tank (50) is provided which separates the non-condensible gases, thereby eliminating pressure buildup in the storage tank. The non-condensible gases are vented back to the system via an oil separator (24) to selectively provide positive pressure for vacuum relief. The system also includes an oil separator (42) for refrigerant which has passed through a compressor (40) with a feedback line (44) to return the oil to the compressor. The system also includes filters (14, 32 and 34), a cooling coil (46); a condenser (48); and a storage tank (54) for immediate re-use of the refrigerant. <IMAGE>

Filed: 1993-06-18
Abstract: A method of manufacturing flying surface and fuselage portions for an aircraft includes the steps of forming respective upper (44) and lower (46, 48) flying surface and fuselage skins at least one of which is an integrated i.e. unitary or one-piece flying surface and fuselage skin; forming a frame (24) including a plurality of transverse integrated fuselage and wing spar elements linked in longitudinal spaced apart relationship by longitudinal support members for supporting the respective upper and lower flying surface fuselage skins; machining the frame so as to match the contours required for the inner surfaces of the upper and lower flying surface skins; and attaching the respective upper and lower flying surface and fuselage skins to said frame. In this way the flying surfaces (wings, for example) and fuselage are both formed from the same structure (frame 24). Thus, the requirement for wing to fuselage attachment points is obviated, therefore saving weight and improving aerodynamic efficiency of the aircraft Frame 24 is of metal. Skins (44, 46, 48) may be of fibre-reinforced composites. <IMAGE>

Title: Antenna arrangement for a portable transceiver
Inventor: CHIN MELISSA C
IPC: H04B1/38
Filed: 1993-11-15
Abstract: An arrangement for increasing the level of radiated and received energy in a telescoping antenna 15 while the antenna is in a collapsed position. The increase in energy is obtained through use of a sliding member 22 which projects from the base of the antenna and contacts antenna matching circuitry 23, 24, 13 for making changes to this circuitry when the antenna is collapsed. Initially tuned for resonating signals for transmission and reception with the antenna in an extended position, the antenna matching circuitry is retuned by a switching action provided by the sliding member for more effective resonating of these signals with the shorter length antenna. Gain control circuitry increases the signal levels in both an associated transmitter and receiver when the antenna is in the collapsed position. <IMAGE>

Title: An open loop clutch slip control system
Inventor: JURGENS GUNTER
IPC: F16H59/72
Filed: 1993-12-03
Abstract: A motor vehicles friction clutch is allowed to slip so as to avoid transmission noise from an engine. The clutch is actuated by a control element operated by a working pressure pK. Pressure pK is varied according to engine torque M1, engine speed n1, engine intake pressure pu and a set point value S1. Using the above parameters and operating temperature T with characteristic diagrams 7, 9 and 12 the working pressure pK is calculated in a computing stage 13 using algorithm 14 in which M is the clutch torque and K is a constant relating to the area of the clutch. The friction clutch is used as a lock-up clutch of a torque converter in which case MK is increased, in accordance with relation 17, by a conversion ratio obtained from characteristic diagram 10 using speed n and the converters turbine speed nTurb1. <IMAGE>

Patent GB-946113-A (GB)
Abstract: 946,113. Two-way transmission systems. MODERN TELEPHONES (GREAT BRITAIN) Ltd. April 21, 1961 [April 27, 1960; April 29, 1960], Nos. 14811/60 and 15185/60. Headings H4K and H4R. In a two-way intercommunication system wherein at least one station in the system is provided with separate incoming and outgoing speech amplifiers, switch means at the station are responsive to signals on the line for enabling the incoming amplifier and inhibiting means responsive to outgoing speech prevent the switch means from operating to the outgoing speech. A transducer 10 (Fig. 1) is normally connected to a two-stage outgoing-speech amplifier 14, 15, a two-wire line 16 terminating at the input of an incoming-speech amplifier 12. Limiting amplifiers 17, 18 are connected to the line and the junction of stages 15, 14 as shown and are further connected through rectifiers 19, 20 to opposed relay windings 21, 22. Amplifiers 17, 18 are arranged so that the rectified part of the outgoing speech signals oppose each other equally in relay coils 21, 22 with the result that this relay is unoperated with its contact 11 in the position shown. In response to incoming speech, however, relay 21, 22 operates to switch transducer 10 to the output of amplifier 12 even if this station operator is still talking. In order to prevent switching during short pause in the incoming speech, relay 21, 22 is made slow to release by the connection of a charged (from source 27) capacitor 26 across the control winding 21 by a further relay 23, 24. This relay is slow to operate compared with relay 21, 22 so that transients on the line will not cause overlong operation of relay 21, 22. The station has over-ride facilities in the form of an additional microphone 35 and amplifier 36 connected to a further winding 37 of relay 21, 22. By speaking loudly into microphone 35 the relay can be de-energized even during incoming speech so that transducer 10 is connected via amplifier 14, 15 to line. The relay 21, 22 may be replaced by a static switching device. Thus in Fig. 2, rectifier 19 is reversed and the output of rectifiers 19 and 20 are applied via a resistive network to a capacitor 32. Incoming speech causes a voltage to appear on capacitor 32 which is greater than a biasing voltage applied from source 30 to amplifier 12 so that the latter is switched on, amplifier 14, 15 being switched off before this happens, however, by the application of this voltage via a phase inverter 34 to amplifier stage 14. Again over-ride facilities are provided by 35, 36. Alternative forms of control circuits and the use of separate loud-speakers and microphones are described with reference to Figs. 3 and 4 (not shown) and the use of transistorized amplifiers and Schmitt trigger circuits for the directional switching is mentioned although no circuit details are given.

Abstract: A colour scanner apparatus designed to work at different resolutions includes an array 20 of linear photosensors 24, 26, 28. Each linear array 24, 26, 28 has associated with it a specific colour filter 34, 36, 38 and the sensors are exposed for a predetermined exposure time. One sensor is designated a master sensor and the remainder slaves. For each of slave sensor an exposure delay time is calculated so that upon exposure of the master sensor at the scan start time the slave sensors are not exposed until their respective exposure delay times have expired. This enables the colour correlation of the sensors to be achieved efficiently at various scanning resolutions. <IMAGE>
