Patent GB-2250660-A (GB)
Title: Cordless telephone system using link identification codes
Inventor: MACNAMEE ROBERT JOSEPH GERARD
IPC: H04M1/733
Filed: 1990-12-05
Abstract: Several different cordless telephone networks can cover an overall operating area. Each network has its own link identification code (LID) which when transmitted by a portable secondary station is recognised by the primary stations of one of the networks as being its home LID. In order to make better use of the overall system, one or more network operators may agree to handle call requests from one another, however preference is given to the home network. In order to do this, a primary station receiving a call request, checks the LID and, if it is not its home LID but that of a roamer, it waits a predetermined time or number of channel scans before accepting the call request which is processed by a host primary station in a way which is transparent to the secondary station that it is not its home primary station.

Patent GB-2246257-A (GB)
Title: Switching circuits
Inventor: FLOWERS HOWARD PETER
IPC: G06F13/40
Filed: 1991-06-20
Abstract: Within data processing systems, for example in the NICAM decoder of a television receiver, data signals on a plurality of input lines have to be read and fed sequentially to a serial data bus. Normally for this purpose expensive integrated circuits with several inputs and ouputs are needed. It is an object of the invention to simplify this operation and to use a bus device which is less expensive than devices used up to now. A device having outputs only (for example OP1, OP2) is used for reading the said input lines sequentially. This is achieved by a diode/resistor matrix which is connected between each data input L1, L2, the outputs OP1, OP2 and the common DATA READ line RL. Thus an inexpensive device or devices having outputs only can be used for sequentially reading signals from a number of input lines.
Patent GB-2257107-A (GB)
Title: A carbonated beverage package
Inventor: LYNCH FRANCIS JOSEPH
IPC: B65D85/73
Filed: 1991-06-25
Abstract: A beverage package has a sealed can 1 containing beer 5 with gas in solution and a headspace 6 containing gas at a pressure greater than atmospheric. An insert 7 in the beer has a secondary chamber 13 containing gas at a pressure greater than atmospheric and which communicates through an aperture 15 with an intermediate chamber 14 having an open end 12 and containing beer 5A. On opening the container, headspace 6 depressurises causing gas to be ejected from chamber 13 through aperture 15 and gas to be evolved from solution in the beer 5A. Such evolution rises through the beer 5A to emerge into the beer 5 above the chamber opening 12 to form a head of froth. The open end 12 of the chamber 14 can be located in the headspace 6. The wall 9 of the chamber 14 isolates a major part of the beer in the container from having its gas liberated so that such gas can evolve gradually and naturally to provide sparkle in the beer. <IMAGE>

There is an anchor piece 4 for pinning down the bell to the ground. The anchor pieces have 'eyes' which enable the bells to be additionally secured when they are arranged in a row, by threading a lanyard through the 'eyes' and pegging the ends to the ground. <IMAGE>

Title: Anti-dive independent wheel suspension system
Inventor: MATSUMOTO YOSHIKYUKI
IPC: B60G7/00
Filed: 1991-08-09
Abstract: A wheel suspension system, wherein an upper and a lower part of a wheel carrier (2), rotatably supporting a wheel, are coupled to a vehicle body by way of upper lateral link means and lower lateral link means, respectively, wherein: the upper lateral link means comprises a pair of lateral link members (6, 7), the points of attachment of the inner and the outer ends of each lateral link member (6, 7) of the upper lateral link means being spaced from one another in the longitudinal direction of the vehicle body, one lateral link member (6) of the upper lateral link means having a different inclination to the horizontal from the other lateral link member (7) of the upper lateral link means. By providing a difference in inclination to the horizontal of the lateral link members (6, 7) of the upper and or lower lateral link means an anti-dive property can be obtained. Further, by providing an appropriate inclination to the rear lower lateral link member, the tendency to form a toggle between the knuckle arm (4) of the wheel carrier (2) and the tie rod (5) is reduced. Also, by making the front lateral link member (6, 8) more upwardly inclined than the rear lateral link member (7, 9) for each of the pairs, an anti-dive effect can be produced without changing the caster angle and other property of the suspension system during cornering manoeuvres. <IMAGE>

Title: Raman laser
Inventor: WHITTLEY STEWART TREVOR
IPC: H01S3/30
Filed: 1991-11-08
Abstract: The present invention provides a Raman laser wherein hazardous radiation from a pump laser source 20 is focused by lens 25 via a cell 27 containing a Ram an active medium before passing to an absorbing beam dump 30. Lasing action is maintained within the cell 27 by the action of mirrors 29 and 26 which are respectively totally and partially reflective to radiation generated at the Raman wavelength, and which are both transmissive to the pump beam. A Raman beam exits the cell via partially transmissive mirror 26 is refocused by lens 25 and passes through to the output of the device 31. This configuration provides a Ram an laser where the "eyesafe" Raman beam is generated in a backwards direction relative to the pump beam, so that during normal operation, or in the event that the optics breakdown, or conversion does not take place within the cell, the output beam would not be contaminated by potentially harmful wavelengths at a hazardous level. <IMAGE>

Title: Composite polishing pad for semiconductor processing
Inventor: BREIVOGEL JOSEPH R
IPC: B24B37/22
Filed: 1992-02-19
Abstract: An improved composite polishing pad includes a first layer of elastic material 20, a second, stiff layer 22 and a third layer 23 optimized for slurry transport. This third layer is the layer against which the water makes contact during the polishing process. The second layer 22 is segmented into individual sections physically isolated from one another in the lateral dimension. Each segmented section is resilient across its width yet cushioned by the first layer in the vertical direction. The physical isolation of each section combined with the cushioning of the first layer of material create a sort of "bedspring" effect which enables the pad to conform to longitudinal gradations across the water. The third layer 23 may also be segmented as shown, resulting in the formation of a plurality of tiles 25 separated by channels 26. <IMAGE>
