Title: Liquid crystal display device
Inventor: CHAPMAN JEFFREY ALAN
IPC: G02F1/1339
Filed: 1985-11-15
Abstract: A liquid crystal display device has a spaced pair of electrode-carrying substrates (10, 11) with a layer of liquid crystal material (24) therebetween in a display area and joined by a peripheral sealing frame (20) of epoxy adhesive. To avoid possible contamination of the liquid crystal material either by epoxy of the frame or by contaminants permeating therethrough, a barrier wall (22) a polyimide is disposed alongside the sealing frame over at least a major part of its length and extends between the two substrates to separate the liquid crystal material in the display area from that part of the frame. <IMAGE>

Title: Push button multi-contact electric switches
Inventor: BEER BRIAN
IPC: H01H13/64
Filed: 1986-01-16
Abstract: An electric switch comprising a base member 1 supporting a pair of contact sets each including at least one fixed contact and a movable contact which is biassed to one position by means of a spring 7 and which is actuatable to another position by applying a force to the spring by means of an actuating plunger 19 extending through a hole in a cover 2 for the switch mechanism. The actuating plunger is provided with two laterally extending actuating arm 19a each of which is arranged to engage with one spring 7 to cause actuation of one of the pair of contact sets and the plunger also includes a bifurcated portion defining two legs 19c which closely straddle a guide portion 21 on the base member. The actuating surface 19b of one arm 19a may be lower than the actuating surface of the other arm if sequential operation of the two contact sets is required rather than simultaneous operation. The springs engage the movable contacts with one end, the other end of each spring engaging a metal pin of a diameter chosen, to provide the required spring tension, from a set of different diameter pins. The fixed contacts are held in place by projections on the cover 2, which includes other projections engaging in or through the base 1 for cover and switch location. <IMAGE>

Patent GB-2198798-A (GB)
Title: Disconnectable pipe joints
Inventor: KIEZEBRINK WILLEM
IPC: F16L37/12
Filed: 1987-08-12
Abstract: A disconnectable pipe joint comprises a male pipe part with an outer shoulder and a female pipe part with an internal recess. The two pipe parts are coupled in a tensile resistant way by means of a radially resiliently expansible coupling ring member being retained in a groove in the female pipe part due to expansion by means of a locking member pushed below said coupling member. A snap fit connection between a rib on the locking member and a groove on the outer side of the male pipe part ensures a good fastening between said male pipe part and said locking member. The coupling member is sufficiently loosely retained in said groove and is provided with a flexible cord for easily pulling coupling member out of the groove and for controlling the presence of coupling member. The male pipe part bears a check ridge indicating the distance to which the locking member must be pushed inwards for expanding the coupling member. The outer shoulder, the groove and check ridge may be formed on a sleeve which can be connected with the male pipe part by means of an adhesive. The male pipe part together with the sleeve and/or coupling member may be presented to a customer in a shrink film surrounding these parts. <IMAGE>

Title: Oscillating-vane pumping and transmission device
Inventor: EGAN MICHAEL JOSEPH
IPC: F04C9/00
Filed: 1988-06-08
Abstract: The device comprises a housing in which are mounted three sector-shaped vanes 8-10.

Title: Regulating the wall thickness of an extruding parison
Inventor: MASKELL STANLEY GEORGE
IPC: B29C48/475
Filed: 1988-07-14
Abstract: A method of controlling the wall thickness of a parison for a blow-moulding operation, during the extrusion of the parison, employs a die 10 having a movable plug 15 controllable to adjust the die gap. The volume rate at which the thermoplastic material 12 is extruded is controlled, and the position of the free end of the parison (which position is directly related to the parison length) is monitored by a linear array of photocells 28 arranged close to the advancing parison. The die gap is then adjusted to values empirically determined as appropriate for the instantaneous parison length. <IMAGE>

Abstract: Apparatus for performing time-base correction of a video signal reproduced from a recording medium e.g. a disk 1 or a magnetic tape, includes means for effecting coarse adjustment by controlling the speed of the medium drive motor 2 in response to the detected phase difference 10 between a reproduced sync signal (h) obtained from the signal reproduced from the recording medium 1 and a reference sync signal (r), and means for effecting fine adjustment by writing data obtained by sampling the reproduced signal according to a write clock signal obtained from the reproduced sync signal (h) into a memory 20, 21 sequentially from a predetermined address according to a write count starting signal WST generated in synchronism with the reproduced sync signal (h), and subsequently, reading out the data sequentially from the predetermined address according to a read count starting signal RST generated in synchronism with a spindle reference signal output from a memory controller 11 whose phase is changed 114 according to a jump command (a) generated in a special playback mode e.g. still-picture or double-speed playback. In addition when the time interval between generation of either one of the write count starting signal WST and the read count starting signal RST and generation of the other one becomes less than a predetermined period, the phase of the reference sync signal (r) is adjusted to have a predetermined phase difference e.g. zero, with the phase of the spindle reference signal to thereby prevent the same signal being played- back during two successive horizontal lines. …<IMAGE>…
