Title: Radio frequency tracking loop
Inventor: WONG ANDREW CHI CHUNG
IPC: H04B1/707
Filed: 1987-03-31
Abstract: A costas-loop carrier-recovery circuit includes digitisers (20, 21), correlators (18, 19) and a peak-tracking circuit (22) in each I & Q arm. The correlators produce a peak output which indicates the degree of correlation between the input pseudo-random code and a reference code. The peak tracker holds the values (23, 24) which are multiplied together (16) to produce the loop error voltage which will drive the VCO (13). The invention is applicable to direct-sequence, binary-phase-coded, spread-spectrum systems. <IMAGE>

Patent GB-2205697-A (GB)
Title: Automotive electric storage battery power system
Inventor: GUTHRIE ALLAN GEORGE ALEXANDER
IPC: H02J7/14
Filed: 1987-06-11
Abstract: An automotive electric storage battery 2 of secondary type in situ in a motor vehicle is connected to the electric components 4 of the vehicle and connected in parallel with a primary battery 6 of higher voltage (e.g. 18 volts) with the interposition of an electric resistance 12 and a diode 10 which prevents current flowing from the electrical components of the vehicle, e.g. the alternator, through the primary battery. The state of charge of the secondary battery 2 is substantially maintained for an extended period of time because, when the vehicle engine is not running, the primary battery 6 supplies a substantial portion (e.g. initially 90 per cent or more) of the residual electrical demand of components which are partly or wholly energised at all times, such as a clock and a computer. The arrangement is of particular use when a vehicle is exported, since the secondary battery 2 will still be able to start the engine on arrival at the destination, whereat the primary battery 6 may be discarded. The battery 6 may be coupled to battery 2 via the cigarette lighter socket in the vehicle. <IMAGE>

Title: Rotary printing machine plate tensioning apparatus
Inventor: JESCHKE WILLI
IPC: B41F27/12
Filed: 1989-02-28
Abstract: Rotary printing machine plate tensioning apparatus which makes use of tensioning rails resiliently mounted in a clamping channel 3 provided in the plate cylinder 1, comprises stressing means to hold a printing plate 2 in register and under tension in the circumferential direction of said plate cylinder, wherein the tensioning rail 5 for the leading end of the plate is mounted on elements designed as leaf-type springs 15 permitting a spring action of this tensioning rail only in the circumferential direction of said plate cylinder, whereas transversely with respect to said direction there is substantially no resilience, and wherein the tensioning rail 4 for the trailing end of the plate is mounted on elements designed as "round-rod" springs 12 permitting a spring action of this tensioning rail in the circumferential and also the axial direction of said plate cylinder. The present apparatus enables the printing plate to be tensioned in a particularly precise and exact manner, without the need for slide guides for the tensioning rails.

Title: Linearly operating pump comprising spiral formations
Inventor: GRANT ALEXANDER
IPC: F04B3/00
Filed: 1989-06-08
Abstract: A linearly operating pump comprises a first, stationery plate and a second movable plate each having an identical, raised, right-angled spiral formation (14, 20) upstanding therefrom. The plates are assembled facing one another with their spirals (14, 20) rotated through 180 degrees relative to one another such that they are interleaved. The topmost surfaces of the spirals (14, 20) are adapted for sliding, sealing contact with the plates and their walls for sliding, sealing contact with one another. The thickness of the walls is equal to half the spacing between corresponding walls of successive turns, and one or more inlet/outlet ports (22, 24) are formed in at least one of the plates adjacent the centre of its spiral. Cyclical, linear movements of the second plate in the directions A, B, C and D causes fluid to be admitted at (26, 28), compressed, and discharged at ports (22, 24). Reversal of the motion causes the device to operate as a vacuum pump. The device is particularly suited to be driven by linear electric motors and is thus suited to microprocessor control. <IMAGE>

Title: Sealing arrangement and torsional actuator incorporating same
Inventor: MUMFORD MICHAEL ANTHONY
IPC: F16J15/48
Filed: 1990-03-28
Abstract: A seal for facing surfaces (13, 41) of two relatively movable members comprises a sealing member (38) disposed in a groove in one member, having a sealing face (40) engaging the other member and an inclined wedge face (42) facing the base of the groove to be engaged by a complementary wedge face (43) of a thrust member (39). The fluid under pressure is supplied to the base of the groove to act on the thrust member so that the members (38, 39) fill the groove and the sealing member has its face (40) urged into engagement with the facing surface (41) of the member (16). The seal is advantageously applied to a fluid pressure operated torsional actuator, for sealing between end faces of the rotor and end parts of the actuator casing, annularly around the shaft on which the rotor is supported, and a shuttle valve arrangement supplies the seal with fluid from the actuator chamber containing fluid at the highest pressure.

Abstract: 903,791. Spark erosion apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 8, 1960 [Jan. 13, 1959], No. 751/60. Class 83 (4). In a spark erosion machine in which an electrode 1 vibrated against the work 18 by an electromagnetic device 13 supplied with pulsating current is carried by a holder 2 resiliently connected to a guide member 8 frictionally held on a support 9 and in which as the electrode 1 advances an abutment 17 on the holder 2 advances the guide member 8 by impact, an auxiliary device 22 is operative on undue short circuit between the electrode 1 and the work 18 to retract the electrode to allow normal working to restart. The devices 13, 22 are coils mounted in block 4 resiliently carrying the holder 2 and resiliently connected to the guide member 8. A counterbalance weight 12 is prevented from lifting the electrode by adjustment of friction pads 11 between the guide member 8 and the support 9. When the electrode 1 sticks to the work 18, the full voltage of the direct current source supplying the sparks is applied to operate a relay 20 to connect the same or a different direct current source to the coil 22 which raises the electrode 1.

Abstract: Intake tracts 10, 12, 14 and 16 are connected to a common plenum chamber 18 with a passage 20 for supplying air to all the engine intake ports. The tracts 12 to 16 are arranged to open into the plenum chamber 18 in pairs associated with intake ports of which the intake valve events do not overlap, the ends of each pair of tracts disposed within the plenum chamber 18 being arranged directly facing one another and being separated by a gap 22 which is sufficiently wide to permit air flow between the respective tracts and the common passage 20 but which is sufficiently narrow to couple most of any pressure wave energy emanating from one tract directly into the other tract. An elliptical container (30, Figs. 2 and 3) within the chamber 18 may have the tracts 10 to 16 connected to the container aligned with foci of reflection of sound waves by the container walls to enhance pressure wave coupling. The tracts 10 to 16 may be connected to parallel plates (42, Figs. 4 and 5) having an inlet pipe (46) for air flow between the plates to provide vortex throttling of air flow to the tracts. <IMAGE>
