Title: Mobile radio communication system
Inventor: ELDER JONATHON
IPC: H04W4/12
Filed: 1989-10-30
Abstract: A radio communications system, particularly a cellular system, has base stations BS for providing a bi-directional radio communication link with a mobile station MS. A messaging centre SCM is connected to the base stations for storing an incoming message for forwarding to a mobile station using the system. Each mobile station MS has a timer, and during a low power consumption "off" state of the mobile, the timer periodically switches the mobile to an on state to effect a location registration update communication procedure with the base station network. In response to this communication, the messaging centre SCM is caused to send any stored messages to the mobile via the base station network. <IMAGE>

Title: Determining true azimuth in the surveying of boreholes
Inventor: RUSSELL ANTHONY WILLIAM
IPC: E21B47/022
Filed: 1990-02-06
Abstract: Borehole surveying methods and apparatus for surveying the true longitudinal magnetic field within a substantially non-magnetic drill collar occupying the part of a borehole being surveyed, despite the collar being of insufficient length to provide longitudinal magnetic field measurements which are uncorrupted by the longitudinal magnetic influences of adjacent magnetic drill string and bottom-hole assembly components. A plurality of longitudinal magnetic field measurements are made by a static instrumentation package at fixed known longitudinal positions within the collar, or by a free-falling instrumentation package at known times or at known increments of time as the instrumentation package moves through the collar. These measurements provide a longitudinal-position-dependent series of magnetic field measurements BZ(z) which enable the true magnitude of the terrestial magnetic field BZe in the direction of the longitudinal axis of the borehole to be calculated on the basis that BZ(z) = BZe + E(z), where E(z) is the longitudinal-position-dependent longitudinal magnetic field error induced by the magnetism of the drill string and the bottom-hole assembly. Several different methods of calculation are described, including polar and non-polar magnetic error function models. The methods can be extended to a full survey of the borehole heading by contemporaneous measurements of two further magnetic fields in each of two mutually orthogonal axes each also orthogonal to the longitudinal axis, along with contemporaneous gravity vector component measurements in each of these three axes. Relevant methods are described, along with apparatus for carrying out the heading survey methods.

Title: Semiconductor testing method
Inventor: BROWN STEPHEN
IPC: G01R31/302
Filed: 1990-10-17
Abstract: In a method of avoiding use of nuclear radiation (5), eg gamma rays, X-rays, electron beams, for testing semiconductor components for resistance to hard radiation, which hard radiation causes data corruption in some memory devices and `latch-up' in others, similar fault effects can be achieved using a xenon or other 'light' flash gun even though the penetration of light is significantly less than that of gamma rays. The method involves treating a device with gamma radiation, measuring a particular fault current at the onset of a fault event, repeating the test with light to confirm the occurrence of the fault event at the same measured fault current, and using the fault current value as a reference for future tests using light on similar devices. <IMAGE>

Title: Equestrian harness.
Inventor: JANION RAYMOND
IPC: B68B1/04
Filed: 1991-03-26
Abstract: An equestrian harness comprises side reins 10 attached to a bit 11 in a horses mouth. The side reins pass either side of the horses head and are each joined to a strap 12 of generally circular cross-section at buckles 13. The strap passes through a pulley wheel 14 which is attached to a numnah 15 usually worn under a saddle (not shown). The buckles enable the length of the reins to be adjusted to enable the harness to be used on different sizes of horse and to enable adjustment of the head carriage of the horse. The horse is able to raise or lower its head to some degree and push its head forwardly to a small degree but then feels a "stone walling" restrictive force from the side reins 10 secured at the pulley 14 as the side reins become taught when the horse attempts to move its head too far. In contrast, the horse enjoys relative freedom to move its head from side to side since this degree of movement causes the strap 12 to feed freely through the pulley wheel 14. <IMAGE>
