Patent GB-2248419-A (GB)
Title: Method for improving adhesive bonding
Inventor: BOWDITCH MALCOLM RAY
IPC: C09J5/02
Filed: 1990-10-05
Abstract: A method for improving adhesive bonding involves the steps of:     1) cleaning an adherend surface with a wet abrasive;   2) rapidly drying the clean surface by radiant heating; and 3) applying an adhesive or an adhesive primer to the clean dry surface; and is characterised in that corrosion of the adherend surface is prevented and atmospheric contaminants are excluded from it by the presence of a contaminant free gaseous layer in contact with the cleaned adherend surface prior to the application of the adhesive or primer. The technique ensures that atmospheric contamination is prevented resulting in improved adhesive bonding. The technique is particularly suitable for metallic surfaces and allows a broader range of adhesives to be employed.

Patent GB-2247313-A (GB)
Title: Optical encoder
Inventor: ICHIKAWA SOUJI
IPC: G01D5/38
Filed: 1991-10-04
Abstract: In an optical encoder of a three grating type (having two relatively movable members, a first grating (12) being attached to one member and a light source 18, detector (20) and second and third gratings (14) and (16) being attached to the other member), the pitch P2 of the second grating is set at a value larger than the pitch P1 of the first grating, and the length of a light transmitting portion of the second grating is set at a value smaller than the pitch P1. With this arrangement, the incoherency between beams transmitted through the second grating is improved and a SN ratio of a detection signal is raised. Further, in a reflection type optical encoder the first grating is a reflection grating and the second grating and third grating (14) and (16) are spaced apart in the same plane on one member. A plurality of the third gratings (16), different in phase from each other may be formed for directional discrimination. The second grating and single source may be replaced by an array of sources, and the third grating and single detector by an array of detectors. <IMAGE>

Title: A fuel pipe
Inventor: PARDY RONALD
IPC: F16L11/12
Filed: 1992-04-01
Abstract: A fuel pipe has an inner tube 32a of non-circular cross-section surrounded by a sheath 34. Fuel flows through the inner tube and any pressure fluctuations in the inner tube result in a flexing of the tube walls to approach more closely to a circular configuration. When the tube walls flex, deformation of the sheath 34 takes place to absorb energy and to prevent the pressure pulse from producing noise. The sheath may be of foam rubber co-extruded with a tube of nylon. The cross- section of the tube may be triangular as shown, tri-lobal (Fig. 3 not shown) or flat (Fig. 4 not shown). <IMAGE>

Title: Hydraulic piston and cylinder assembly
Inventor: MASON BRIAN EDWARD
IPC: F15B15/18
Filed: 1993-03-15
Abstract: A self-contained hydraulic pump and working piston and cylinder arrangement comprises a cylinder 1 with a piston rod 7 extending through an annular plug 2 at one end of the cylinder, the opposite end of the cylinder being closed by pump body 3. The cylinder 1 is divided by the working piston 6 into a pressure chamber 24 and a reservoir chamber 19 whose volumes are varied with the stroke of the piston 7. During operation of the hydraulic pump 14, fluid from the reservoir 19 is delivered by the pump under pressure to the pressure chamber 24 causing the piston 6 to retract the piston rod 7. In order to release the pressure in the pressure chamber 24 a manually actuable pressure release valve (28 Fig. 2 not shown) is opened to allow fluid to return to the reservoir chamber 19. <IMAGE>

Filed: 1993-03-16
Abstract: A non-restore division process in which the result of an exclusive NOR operation between the carry-out from each addition or subtraction operation, and the highest order bit of the dividend or interim dividend provides the quotient bit for that particular iteration. The Most Significant Bit of the dividend or interim dividend is stored in a separate latch at the input of the exclusive NOR gate so that the ALU is not required to be one bit larger than the dividend. (Eg. a 32 bit division operation will not require a 33 bit ALU.) <IMAGE>

Title: Synchronization in frequency-hopping communications
Inventor: ASHDOWN MICHAEL BRIAN
IPC: H04B1/713
Filed: 1993-06-02
Abstract: A method of communicating between two or more radios each capable of transmitting and receiving signals between one another on two or more radio channels wherein the radios hop from channel to channel in a pseudo-random sequence. The method comprises establishing hop synchronization between the radios utilizing a first cycle and operating the radios in a communication mode utilizing a second cycle. The first cycle is shorter than the second cycle so as to facilitate rapid synchronization while preserving the benefits and security obtained through the use of longer cycle length during communication mode.

Title: Liquid metering system
Inventor: HALL JOHN BRIAN
IPC: B67D1/00
Filed: 1994-02-02
Abstract: A liquid flow system primarily for dispensing beverage has a tap 4 by which beverage is drawn on demand through pipe 6 from a bulk supply. The pipe 6 includes a chamber 10 having a member 11 which is displaced during beverage flow to permit light from an emitter 12 to be applied through the beverage to a light sensor 13 that provides a signal to a microprocessor 17 actuating a timer 17A. Following a predetermined time during beverage dispensing consistent with a predetermined volume of beverage being dispensed, the microprocessor 17 actuates a stamp 21 which is applied to a customer record card 24. The card 24 forms part of a sales promotion whereby when sufficient volumes of beverage purchased have been recorded, the card can be submitted for a reward. In a modification the card 24 includes a magnetic stripe and the stamp 21 is replaced by an electronic head for writing to the magentic stripe and recording predetermined volumes of beverage purchased. The sensor 13 is responsive to variations in intensity of light applied thereto through the beverage so that the characteristics of the sensor 13 can be predetermined for a predetermined beverage which controls actuation of the stamp 21 only when that predetermined beverage is being dispensed. <IMAGE>
