Patent GB-2054974-A (GB)
Title: Tracking Mode Couplers for Use in Radar and Communications Tracking Systems
IPC: H01P1/161
Filed: 1980-05-15
Abstract: The invention provides a tracking mode coupler capable of substantially complete extraction of tracking mode signal energy, to the exclusion of all unwanted modes, for use in either a radar or a communications tracking system. In essence the coupler comprises a primary waveguide 1 which will propagate a dominant mode and at least one higher order tracking mode from a received off-axis signal at the operating frequency, and an oversized secondary waveguide 3 which is coupled to the primary waveguide 1, preferably by means of two separate coupling apertures 6 and 7, in such a way that the tracking mode or modes in the primary waveguide propagate the dominant mode in the secondary waveguide, and the dominant mode in the primary waveguide propagates a higher order mode in the secondary waveguide. In addition, the primary waveguide 1 has a mode selective filter 9, preferably a reflecting filter, for allowing only the dominant mode in the primary waveguide 1 to pass, and the secondary waveguide 3 has a similar mode selective filter 8 for allowing only the dominant mode in the secondary waveguide to pass. Consequently the output from the secondary waveguide 3 is derived solely from the higher order tracking mode or modes propagated in the primary waveguide 1. <IMAGE>

Patent GB-2052018-A (GB)
Title: Non-return Valves
IPC: F16K15/14
Filed: 1980-06-20
Abstract: A non-return valve has two apertured discs 6 and 7 superposed in a body 1 with the apertures 9, 10 of each disc out of register and overlap with those of the other. One of the discs 7 is adapted to flex away from the other disc 6 in response to fluid pressure applied thereto through the apertures 10 of the other disc, thereby allowing fluid to flow through the apertures of the two discs in one sense of direction. In response to pressure applied to the flexible disc 7 in the opposite sense, however, it bears against the other disc 6 to close the apertures 9, 10 of both discs and thereby prevent fluid flow in the opposite sense of direction. <IMAGE>
Patent GB-2048599-A (GB)
Title: Control circuitry for gated diode switches
IPC: H03K17/567
Filed: 1979-12-17
Abstract: A gated diode switch (GDS1, GDS31) requires a voltage applied to the gate which is more positive than that of the anode or cathode in order to break current flow between the anode and cathode. In addition, a current of at least the same order of magnitude as flows between anode and cathode must be sourced into the gate of the switch to break current flow. The use of a second gated diode switch (GDS2, GDS32) coupled by the cathode (terminal 222, 322) thereof to the gate of a gated diode switch (GDS1, GDS31) which is to be controlled provides a high voltage and current capability circuitry for cutting off (interrupting) or inhibiting current flow through the gated diode switch (GDS1, GDS31). The state of a gated diode switch (GDS1, GDS31) is thus controlled by a second gated diode switch (GDS2, GDS32). The state of the second gated diode switch is controlled by a voltage control circuit having only relatively modest current handling capability.

Title: Multi-column vending machine
IPC: G06M3/08
Filed: 1980-10-17
Abstract: A vending machine counter in which each drawer (14) has an operating plate (44) which engages a loop (30) formed in a rotatably mounted rod (24) when the drawer is opened. The engagement causes the rod to rotate in the direction of arrow (48) until an arm (50) secured to the rod engages an arm (50) connected to a counter (52) to cause the opening of the drawer to be recorded. The rod (24) is biased towards the position shown by a spring (32). The recording on the counter (52) is visible through a recess (60). <IMAGE>
Patent GB-2068474-A (GB)
Title: An hydrostatic machine
IPC: F04B1/04
Filed: 1981-01-02
Abstract: The hydrostatic machine has a stroke ring (22) on the inside of which delivery elements are supported and slide for the purpose of stroke generation. The stroke ring which usually revolves can be prevented from rotating by an arresting device. This device consists for example of a piston (26) on which acts a spring (30) against the delivery pressure. If the delivery pressure is low then the spring forces an extension (27) on the piston (26) into a recess (31) in the stroke ring (22) whereupon the latter is prevented from rotating. If the pressure has reached a predetermined value then the piston (26) is moved against the delivery pressure so that its extension (27) is removed from the recess (31). The stroke ring (22) can then revolve once again which is desirable under high pressure operation due to the low adjusting forces and even wear. At critical operating conditions, that is to say when the delivery pressure is zero or at a low delivery pressure, the stroke ring must be prevented from rotating since otherwise wear on the machine parts can occur. <IMAGE>
Patent GB-2068679-A (GB)
Title: Loudspeaker grilles
IPC: H04R1/02
Filed: 1981-01-06
Abstract: The invention relates to loudspeaker systems comprising at least one transducer mounted in an enclosure to radiate through an aperture in a wall of the enclosure, said aperture being covered by acoustically transparent material. Usually the acoustically transparent material is mounted on a wooden frame but such a frame causes distortion of the radiated sound. Accordingly the wooden frame is replaced by a metal frame designed to have an acoustically transparent peripheral portion which does not distort the radiated sound to the same extent as a wooden frame. The frame may consist of two parallel parts 12, 13, one of which is attached to a wall of the enclosure by means of pegs locating in corresponding holes 14. Alternatively, if the frame is made of resilient material such as steel wire, it may be held in position by locating a first part of the frame in a recess formed in the enclosure wall. <IMAGE>
