Title: Security panel arrangement
Inventor: ROBERTSON JOHN
IPC: E05C17/00
Filed: 1984-04-25
Abstract: A security panel 12 is pivotally mounted adjacent to an aperture closure member, such as a door 10, and releasably secured by a locking bar 16 to the door. When the door 10 is opened contact is made with the locking bar 16 and panel 12 so that further movement is prevented. Conversation or transaction may take place whilst physical protection is provided by the panel 12 and forced entry is deterred. Normal use of the door 10 is obtained by releasing the locking bar 16 and pivoting the panel 12 to a dormant position. Egress and access through the panel is achieved via the gate 20. <IMAGE>

Title: Method and apparatus for aligning a filter onto a color charge-coupled device imager
Inventor: GALE MICHAEL THOMAS
IPC: G02B5/20
Filed: 1986-01-13
Abstract: A filter is mounted on a surface of the substrate of a charge-coupled device imager (34) by mounting the imager on a chuck (12) of an aligner. The imager (34) is sufficiently thin to be transparent to visible light. The chuck is supported for x-y-??? and vertical movement. Some adhesive is applied to the surface of the imager substrate. The filter which is mounted on a holder (90) is placed on the substrate surface over the adhesive. The chuck is moved vertically upwardly until the filter holder is within a gimbal (40,42) mounted over the chuck, and the filter holder is secured in the gimbal. The chuck is moved vertically upward slightly to cause the adhesive to spread out between the imager substrate and the filter and to cause the filter to become parallel to the imager substrate. A light beam (from 96) is then directed through the imager substrate and the filter from below the imager substrate. The light is viewed through a microscope (56) which is above the filter. While viewing the filter and imager through the microscope, the imager is moved with respect to the filter in the x, y and ??? directions until the filter pattern is aligned with the imager array. The adhesive is then cured to secure the filter in proper position on the imager. <IMAGE>

Title: Operating mechanism for domestic taps
Inventor: GOODALL FREDERICK
IPC: F16K31/52
Filed: 1986-08-13
Abstract: A tap control mechanism operates between fixed stops which may be formed by the ends of a cam slot which receives a pin 5 on a spindle 2 with a screw threaded end (Fig. 1) fitting into an axially-movable closure member 3.

Title: Circuit arrangement with two serially connected high-voltage transistors
Inventor: GENT DEREK JAMES
IPC: H03K17/0412
Filed: 1986-12-19
Abstract: A pair of high voltage bipolar power transistors (TR1, TR2) are serially connected through an inductor (L) to a supply with associated components connected to the transistors which determine various periods of operation. In order to ensure that the transistors (TR1, TR2) are rendered non-conducting simultaneously sensors (S1,S2) sense their change in base current to produce pulses in monostable multivibrators (M1, M2) whose relative phases are compared in a digital phase comparator (PC). The drive for each transistor (TR1, TR2) from its associated driver stage (DR1, DR2) is via an associated amplitude control device (AC1, AC2) which controls the amplitude of the drive pulses for the transistors one of the devices (AC2) being variable and controlled by the output of the phase comparator (PC). The amplitude of the drive pulse is changed to change the amount of charge carriers in the transistor (TR2) until their storage times are equal to ensure the simultaneous non-conduction of the transistors (TR1, TR2). <IMAGE>

Title: Magnetically controlled two-way valve
Inventor: RAMILLON JEAN-PIERRE
IPC: F16K31/06
Filed: 1985-07-17
Abstract: The valve comprises a magnetic core (7) carrying a valve plate (4) to obturate a seat (5). When the valve has taken its opening position by means of a magnetic attraction, it keeps said position because the fluid flow in the seat (5) towards the outlet (3) creates a depression in the conduit (20). Said depression is transmitted through the drilling (16) up to the chamber (17) which is opposite to the core (7). The depression is sufficient to retain the core (7) in an open position against the return force of the spring (12).

Title: Information storage
Inventor: PARKER ANDREW
IPC: G11B7/0055
Filed: 1988-03-26
Abstract: A liquid crystal storage device comprises a nematic liquid crystal polymer contained between two transparent plates the inside surfaces of which are coated to provide electrodes for applying an electric field across the nematic polymer for erasure purposes. A laser scans the device and applies heat to address regions of the nematic polymer, the direction of orientation of the molecules of the polymer being controllably variable over a range of directions dependent on the direction of scanning, such that information is stored as the angle of orientation imparted to the molecules of the nematic polymer by the laser. The stored information is viewed by passing plane polarised light through the storage device and hence through a pleochroic analyser.

Title: Tape tensioning device for a tape recorder
Inventor: TANAKA SHINSAKU
IPC: G11B15/10
Filed: 1990-02-14
Abstract: The device automatically eliminates possible slack in a tape within a tape cassette (5) in response to loading of the tape cassette (5) in a tape recorder starting a tape feeding motor (18), rotation of which is transmitted to a specific one (2a) of reel spindles (2a, 2b) by way of a tape tensioning rotation transmitting device (25) while the other reel spindle (2b) is inhibited from rotation by a brake device (16), thereby to eliminate possible slack of the tape within the tape cassette (5) to tension the tape. A tension detecting device (36) detects this and causes a controlling member (11) to disconnect the rotation transmitting route by the tensioning rotation transmitting device (25), cancel the braked condition by the brake device (16) and de-energize the tape feeding motor (18) to stop rotation of the motor (18), thereby to prepare for subsequent selection of a tape recorder function, such selection being inhibited until such tape tensioning operation is completed <IMAGE>
