Patent GB-2196685-A (GB)
Title: Key-operable locks
Inventor: ASTON WALTER JOHN
IPC: E05B49/00
Filed: 1986-10-24
Abstract: The lock includes a cylinder 11 rotatably mounted in a body 10. The cylinder has a keyway for accepting a conventional edge profile key, but instead of the usual pin/tumbler arrangement, there is an edge profile follower 17 which is displaceable by the edge of the key as the key is inserted and which coacts with the movable input element 16 of an inductive transducer 16 connected in on a.c. circuit. This supplies signals to a recognition circuit which, if an acceptable edge profile is detected, energises a solenoid 12 to withdraw a detent element 14 which normally prevents turning of the cylinder 11. The transducer of Fig. 2 is a linear variable inductive transducer and also as shown in Fig. 2, the a.c. circuit includes an oscillator 20 which supplies an a.c. signal to primary winding 21 of the transducer, the position of the input element 16 determining the amplitude of output signals from secondary windings 22 of the transducer which are connected to a detector circuit 23 to provide a d.c. output. Such is supplied to analog-to-digital converter 24 which is connected to a microprocessor 25 which is programmed to act as the recognition circuit and having data stored in its memory e.g. regarding keys/times. In the circuit of Fig. 3 the transducer (115) is an inductor forming part of frequency determining network of an oscillator (117) the output of which is applied to a frequency to voltage convector (118). Solenoid 12 operates on detent 14 via overcentre linkage 13. <IMAGE>

Title: Scaffolding or tower
Inventor: PRYOR NORMAN ARTHUR
IPC: E04G1/24
Filed: 1987-06-15
Abstract: In order to reduce cost, a scaffold tower 1 is mobile, and all its running wheels 3 run along the same track 4 to reduce problems of levelling etc. In order to keep the scaffold tower 1 stable both when stationary and when being moved, there is a stabilising arrangement which locates the higher part of the tower 1 with respect to a stabilising track 7 fixed to the roof of the building, the tracks 4 and 7 being parallel as seen in plan. Wheels 21 run along the track 7 and are connected to the tower 1 by means of a restraint arm 8 whose end adjacent the tower 1 is rigidly fixed to a vertical member 9 which has vertically-spaced wheels running in a vertical guideway 15 fixed to the tower 1. The guideway 15 guides the restraint arm 8 so that it moves up and down when the height of the stabilising track alters relative to the tower 1 as the tower 1 is moved along the building. <IMAGE>

Patent GB-2215564-A (GB)
Title: Data communications
Inventor: HARDY DONALD
IPC: H04B5/00
Filed: 1988-02-27
Abstract: A connector device has one part (2) which defines a circular, smooth-walled recess into which a plug projection (22) of another connector part (4) fits. The recess and plug projection have plane mating surfaces (8, 24) behind which are mounted receiver and transmitter induction coils (14, 16). When the parts are mated the transmitter coil of one part is aligned with the receiver coil of the other part to form two serial data links. Each connector part also includes a transmitter circuit and a receiver circuit connected to the respective coils. The transmitter circuit converts one of two input logic levels into a series of oscillations at a frequency substantially greater than the maximum data transmission frequency, and the receiver circuit converts such a received oscillation sequence into a steady logic level. <IMAGE>

Patent GB-2223341-A (GB)
Title: An adhesive fixture
Inventor: LAURESTON PHILIP
IPC: G09F7/12
Filed: 1988-09-29
Abstract: This invention relates generally to adhesive fixtures, but particularly to adhesive ceramic tiles to be used as house numbers for attachment to a suitable attachment surface such as a wall or a door. The fixture has a rear face 3 in which a shallow recess 4 is provided. That part of the fixture which bounds the recess 4 forms a skirt 6 which terminates in a contact surface 8. This surface 8 is so shaped as to form a flush fit with an attachment surface 10. Adhesive means in the form of a powdered cement 12 is located within the recess 4. The cement 12 almost completely fills the recess 4 and is held within the recess 4 by a release strip (14) releasably affixed to the contact surface 8. The fixture is prepared for use by peeling off the release strip (14) and mixing the cement 12 with an appropriate amount of water in the recess 4. The fixture, with the cement 12 still in the recess, is then held in position with its contact surface 8 against the attachment surface 10 until the cement 12 has hardened. Alternatively, the tiles may be made of thermoplastics or fibreglass. The invention may also be applied to coat hooks and brackets. <IMAGE>

Title: Apparatus for removing generally planar articles from a stack
Inventor: SIMMONS ROBERT JULIAN
IPC: B65G59/06
Filed: 1989-03-02
Abstract: Apparatus for use in removing generally planar articles from a stack 2 of articles comprises a rotatable wheel 1. Provided around the circumferential surface of the wheel 1 are plurality of indents 4 having base surfaces 5 whose radial depth varies from zero at their leading ends to a maximum at their trailing ends. The circumferential surface of the wheel is arranged to support the articles in the stack 2 so that as the wheel 1 rotates the lowermost article in the stack 2 is gradually lowered into an indent 4, for removal from the stack 2. The articles may be biscuits, and may be removed by transport on rails 12 under the effect of pushers 14 on endless belt 11. Alternatively they may be inverted by a shroud co-operating with wheel 1, the biscuits being discharged at the "six o'clock" position.   <IMAGE>
Patent GB-2224770-A (GB)
Title: Boot handle assembly
Inventor: PEARSON ARTHUR
IPC: E05B3/06
Filed: 1989-10-12
Abstract: Handle assembly 1' has a handle 3' with wide opposed slots cut into end 3' 6. A retaining ring K has six teeth T1, T2, t1, t2, t3, t4 with tooth T1, T2 being inclined in an opposite direction to the inclination of teeth t1 to t4. Retaining ring K grips shaft 7' with teeth T1, T2 while gripping end 3 min b of the handle 3 with teeth t1 to t4. Ring K thus provides a flange F limiting relative axial movement of base 2 and handle 3 whilst allowing relative rotation of the handle and base. Base 2 may be attached to a boot lid/tailgate of a vehicle or to a garage door. A kit of parts comprising the assembly as well as the retaining ring K for use in the assembly are also claimed. <IMAGE>

Title: Dry gas meter
Inventor: PYE ALFRED EDWARD
IPC: G01F3/22
Filed: 1990-03-20
Abstract: In a dry gas meter of the type having one or more pans (11, 12) across which flexible diaphragms work, flag rods (14, 15) translate oscillations of the diaphragms through a lever system (17, 18, 20, 21, 23, 24, 26, 27, 28, 29) to drive levers (30, 31) having extension tags (33, 34). A valve plate (40) carries pivoted valve covers (45, 46) and the tags (33, 34) extend through valve openings in plate (40) to engage and drive the valve covers to open and close gratings (42, 43) in the plate (40). An electrical reed switch (56) senses the movements of a magnet (54) so as to produce a series of electrical pulses representing the metered quantity. The pulses are fed to electronic circuitry on a board (59) to compute the gas volume used, a temperature compensation signal being provided by a gas temperature sensor. The output volume signal is fed to an l.c.d. display and to a socket for external transmission. The lever system is compactly housed beneath the valve plate (40), and the mechanical power used by the meter is reduced since no drive shafts pass through the plate, the reed switch and electronic system also being beneath the plate. <IMAGE>

Title: Controlling selective printer formats in dependence on code-marks read from the print substrate
Inventor: GILHAM DENNIS THOMAS
IPC: B41J11/46
Filed: 1990-11-22
Abstract: A document processing system is disclosed in which each different form of document bears a machine readable identification unique to that document form and a printer for printing on the documents includes a reader to read the identification. The reading of the identification enables verification that the correct document to be processed has been correctly orientated in the printer. The system is described for use in producing a set of documents in respect of a consignment of items to be carried by one of a number of different carrier services. In response to input of data relating to a consignment of items the system determines the forms required to be inserted sequentially into the printer and, upon verification that the required form is correctly inserted, operates the printer to print data on that form. <IMAGE>
