Title: Time division multiplex communication system
IPC: H04Q11/04
Filed: 1979-06-26
Abstract: A time division multiplex (TDM) communication system includes a number of autonomously-operating modules M0, M1,... M23, each having a control circuit C with its own microprocessor. The control circuits are interconnected by a common control bus CB for data interchange. Each module is connected to its own speech bus SB0, SB1, etc., at the sender side SO and to all speech busses at its receiver side Si. From these busses each module selects its own information. Each time slot is divided into a number of sub-slots, eight in the system described, which is less than the number of modules. A number, up to seven in the system described, of these intervals of the same time slot may be allotted to different subscribers. The blocking probability of such a system is well within acceptable limits. This arrangement allows low speed MOS LSJ to be used. <IMAGE>

Patent GB-2090656-A (GB)
Title: Optical Position Sensing
IPC: G01B11/00
Filed: 1982-01-06
Abstract: The light emitted by a combination of at least two luminescent materials coated 6, on a body 7 varies with position on the body surface, enabling the position and/or orientation of the body to be detected photoelectrically, e.g. by sensing at a fixed detection point either the mean luminescent lifetime or the relative luminescent intensities. The mixing ratio of a pair of materials may vary continuously in one direction along the body, or a uniform mixture may be overlaid by a non-uniform layer selectively absorbing light from one of the materials. A second pair of materials may be used likewise for sensing in a second direction. For discrete position sensing, the body bears uniform areas of different materials. In a further variant, the luminescent strips are overlaid by a binary coded apertured mask and the luminescent light observed via a fixed triple aperture mask is analysed. As shown light from xenon arc lamp 1 is directed via chopper 3, filter 4, dichroic mirrors 8, 9 and optical fibre 5 to the coating 6, and luminescent light is returned through fibre 5, mirror 9 and filter 10 to a detector 11. The mixing ratio of two materials is determined at 12 by phase comparison of the detector output and a signal from chopper 3. <IMAGE>

Title: Multipoint side hung door lock
Inventor: GUYMER BARRY ROBERT
IPC: E05C9/04
Filed: 1982-04-26
Abstract: A multipoint door lock has a latch-bolt, head- and sill-bolts and a dead bolt. A handle on the inside of the door operates a follower 19 for retracting the latch-bolt 18 if turned in one direction, whilst rotation in the opposite direction causes the head- and sill-bolts to be shot. Dead-bolt 21 is shot by means of cylinder lock L having a radial projection 57 which first lifts a plate bearing pin 31 then engages surface 65 in a cut-out in the bolt to drive it outwards and then releases the plate. This also causes pin 31 to travel up limb 64, along straight 63 and down limb 66 of an inverted U-shaped slot in the lock casing, so providing a detent to hold the bolt in its end positions. The dead-bolt operation may occur before or after operating the head- and sill-bolts. A night-latch 20 is provided to prevent withdrawal of the dead-bolt by a key, but is operable only when the head- and sill-bolts are in their fastening positions. <IMAGE>
