Patent GB-2180406-A (GB)
Title: Antenna tracking system
Inventor: WATSON BARRY KENNETH
IPC: H01Q25/02
Filed: 1985-09-06
Abstract: A microwave feed for an antenna, particularly a front-fed symmetric reflector antenna, comprises a primary feed waveguide horn (1) and a plurality of peripheral waveguide horns (2-5) which extend longitudinally alongside the primary horn with their apertures in or near the aperture plane of the primary horn. Each peripheral horn includes means (8), such as a diode, for selectively switching the horn between an operative state in which fundamental mode energy propagating in the primary and peripheral horns at a predetermined beacon frequency has a quadrature phase relationship in the aperture plane of the primary horn which will cause a shift of the secondary beam axis in a predetermined direction at the beacon frequency, and an inoperative state in which the peripheral horn has no effect on the secondary beam axis. By operation of the switching means to render one or more of the peripheral horns operative in a predetermined sequence while the others are inoperative, the secondary beam axis will be scanned. Analysis of the beacon signal strength corresponding to each beam shift will provide tracking information. <IMAGE>

Title: Flexible propulsive fin-mechanically mounted
Inventor: BOOTON ALAN HARRY
IPC: B63H1/36
Filed: 1985-10-02
Abstract: A flexible fin arrangement, when coupled to a prime mover, provides a means of propelling a displacement or submersible body through a liquid. A flexible fin (or fins) 10 are mounted on the end of a radial arm (or frame) 11, the other end of the arm providing a pivot 12 about which the prime mover can exert a semi-rotary reciprocating movement, thus moving the leading edge of the fin 20 through the liquid in an arcing movement, similar to a fish's tail fin movement. <IMAGE>

Title: Device for the axial reciprocation of ink distributing rollers of a printing machine
Inventor: TRAVNICEK MOJMIR
IPC: B41F31/15
Filed: 1986-09-17
Abstract: The amplitude of the axial reciprocation of ink vibrator rollers (1) may be adjusted while the press is in operation. As shown, a control member (11) is pivoted at (25) and bears an arcuate slot (12) along which the end (17) of a connecting rod (7) is constrained to slide when driven by crank (20). A second connecting rod (6) acts between the end (17) and a known type of rocking arrangement 1-5. The slot (12) is such that the control plate may be rotated so as to place the centre of curvature of the slot coincident with rocking axis (26), under which situation no rocking can occur. As the plate (11) is rotated (by wheel 16) the rocking amplitude increases. <IMAGE>

Title: Ultrasonic vibrator
Inventor: MISHIRO SHOJI
IPC: H04R17/08
Filed: 1986-09-26
Abstract: In an ultrasonic vibrator, a plurality of electrode pairs 10, Fig. 2, each including halved electrodes 13, are arranged in a circumferential direction on one surface of an electrostrictive body 11 so as to constitute an electrostrictive element 9, a common electrode 14 being formed on the other surface.

Movement of the diaphragm reciprocates a latch (63) through a series of stops (65 to 68). When the user inhales for the second time, the latch (63) escapes from the last stop (68), a spring (69) is released, the one-way valve is clamped shut by a plate (55), and a probe (73) releases a catch (35) and allows a breathing bag (13) to open.
Patent GB-2190467-A (GB)
Title: Improvements in or relating to moulding
Inventor: WILLIAMS PAUL
IPC: B28B17/00
Filed: 1987-03-27
Abstract: Moulding apparatus includes a filling head 1 for evacuating and filling a mould 3 with plaster of paris. The filling head 1 includes a valve 2 with three inlets 15, (19) and (20) connected to evacuating means, a supply of plaster of paris and a supply of cleaning water respectively. Inlet ports in a valve seat 5 are selectively aligned with a port 14 in a valve member 6 by rotation of the member 6 or, in the modification of Figure 7, by rotation of the valve seat 5. The filling head is translatable to a waste disposal (25) where it is flushed with cleaning fluid between successive filling operations. The inlet channel defined by the valve components is of cylindrical shape so that the valve may be readily purged of any solidified obstruction by flushing through the valve gate into the waste disposal. The apparatus has particular application in the moulding of casts having fine detail. As shown in Figure 9, each inlet port may be surrounded by a resilient sealing ring 77 which is recessed both on the surface contacting the valve member 6 and on its lateral surfaces. <IMAGE>

Title: Fuze systems
Inventor: JOYCE BRIAN CHARLES
IPC: F42C13/02
Filed: 1987-09-03
Abstract: In order to permit the use of smaller warheads on missiles, ie. with less of a blanket effect, there is proposed herein a fuze including an imaging device for imaging a target and a processor which conceptually visualises the target and the swath or explosion pattern of the warhead and initiates detonation when the two coincide. The relative velocity of target and missile can be taken into account as can the recognition of predetermined 'vulnerable' areas of the target. The fuze could also be used on other weapons, eg. static or slow moving weapons.

Title: Latch mechanism
Inventor: WONG KWAN-YU
IPC: E05B65/08
Filed: 1987-12-24
Abstract: The latch mechanism e.g. for a door, window, metal gate or grill, comprises a latch member 1 biassed by spring 9 into an engaging position to engage an engaging member 16. To release the mechanism the member 1 is urged against the spring 9 by operation of a key and cylinder arrangement carrying a cam in the form of a lever 23 which engages in a detent 27 formed on an arm 26 of the latch member 1 to move the latch member to release the engagement and to lock it in the non-engaging position. As shown member 1 is slidably mounted in a housing 2 mounted in the stile of a door or window and the member 16 of mushroom shape is mounted on plate 17 attached to the door or window frame although this mounting arrangement may be reversed. As the door or window is closed member 16 passes through aperture 15 and rounded surface 20 contacts chamfer 14 on toe 13 of the latch member 1. In the embodiment of Figures 4, 5 the latch member 1 can be locked in the engaging position by a deadlock comprising a key and cylinder arrangement 28 carrying a lever 29. The invention is applicable to mortise arrangment. <IMAGE>

Title: Surgical slipper
Inventor: LOGAN R ERNEST FERGUS
IPC: A01K13/00
Filed: 1988-07-01
Abstract: A surgical slipper 3 for the treatment of lameness in cows, comprises a claw shaped plastic container which slips over a healthy claw in the manner of a shoe and which is made to individually fit each animal by the use of a void filling self-polymerising caulking compound. The surgical slipper can be made in various sole thicknesses or the correct thickness can be attained at the time of fitting by the use of stick-on plastic slivers which increase the overall depth of the healthy claw thereby lifting the diseased claw off the ground so as to aid the healing process under no-load conditions. The slipper can be made by injection moulding or by template cutting followed by weld or adhesive fabrication. The caulking compound is a mineral filled, twin pack resin system which polymerises in a conveniently short time at, or near, ambient temperature. <IMAGE>

Abstract: A corkscrew comprises a housing (12) in which is screw-engaged a barrel (14). The barrel has an internal screw thread (56), of opposite hand to its outer thread (52), engaged with the housing, and a drive member (16), carrying a screw (24), and a handle (22) has a projection (58) engaged in the internal screw thread. The bottom of the barrel has a cork engaging portion (66) for gripping the top of a cork when the housing is seated on the neck of a bottle with the screw piercing the cork. The handle (22) is rotatable in one direction to drive the screw into the cork. The projection (58) moves down the internal thread (56) and engages a stop (72) so that continued rotation raises the barrel with the drive member to draw the cork into the housing. On reverse rotation of the handle, the projection moves up the internal thread to withdraw the screw such that the cork is pushed out and released from the screw by the cork engaging portion (66). The projection engages a stop (74) so that further reverse rotation returns the barrel to the initial position. <IMAGE>
