Patent GB-2123215-A (GB)
Title: Group aerial
Inventor: PETRI ULRICH
IPC: H01Q21/06
Filed: 1983-06-24
Abstract: In a group aerial having parallel radiators 3 with linear polarization, a reflector grid of parallel, electrically conducting plates 1 is disposed behind the individual radiators. The plate spacing is less than half the operating wavelength. The plates act as hollow waveguides with a critical wavelength which is shorter than the operating wavelength of the radiator elements. As a result, an aperiodic, loss-free attentuation of the waves results between the plates and hence a reflection of the energy falling on the reflector grid. <IMAGE>

Title: Arrangements for enabling the connection of one or more additional devices to a computer
Inventor: KARLIN DAVID
IPC: G06F12/06
Filed: 1984-01-12
Abstract: Additional devices, such as extra memory boards, peripheral interfaces and network interfaces, are connectible to a computer 11 by means of multi-pin plug and socket connections. The sockets 3-7 are connected in parallel to circuits of the computer and each has a plurality of additional contacts selectively connected to a reference voltage or a signal source in the computer, the combinations of connections of the additional contacts being different for the different sockets. Each additional device includes comparison logic for comparing input address data with signals or voltages derived from the additional contacts, so that additional devices plugged into the different sockets can be addressed separately by reference to the socket into which they are plugged. A CARD SELECT signal from the computer is used to inhibit spurious responses from the additional devices to an address signal combination which might accidentally be the same as that of an additional device. <IMAGE>

Title: Plastics wheel
Inventor: DERRY NORMAN SIDNEY
IPC: B60B5/02
Filed: 1985-07-01
Abstract: Fibre reinforced synthetic resin wheels at economic cost for motor vehicles have encountered problems due to creep arising from high temperature cycling in use, causing relaxation of the wheel fastenings. Two-piece fibre reinforced synthetic resin wheel 1 has a wheel fixing portion 3 of low heat conductivity and high temperature distortion resistance which has different material properties to a wheel portion 2 to which it is bonded. Portion 3 may be mechanically keyed to portion 2 to facilitate transmission of torque and/or receive support against bending loads. Wheel fixing nuts preferably engage load bearing inserts 7 through which wheel mounting studs pass to secure the wheel to a brake assembly. Torque on the wheel nuts maintains a safe level due to the properties of wheel fixing portion 3, whilst wheel portion 2 is protected from excess temperatures by the heat barrier provided by wheel fixing portion 3. <IMAGE>
