Title: Direction-finding for cellular radio
Inventor: MOHEBBI BEHZAD
IPC: G01S3/20
Filed: 1996-06-27
Abstract: The direction to a cellular telephone handset from a base station is determined at the base station by an antenna system having two or more independent radiation patterns. The radiation patterns of the antennas differ in a known manner. The power differential between the received signals is determined and compared with previously determined data representative of the spatial differences between the radiation patterns of the antennas to determine the direction of the handset relative to the base station. The different radiation patterns may be obtained by switching parasitic elements in and out (connecting or disconnecting a load) during, or between, pulse sequences. The range of the handset may be obtained from the received signal strength. Time-separated range and direction measurements may give the handset's speed, which may be used to control hand-over.

IPC: F23D14/14
Filed: 1996-08-14
Abstract: A gas burner for using a full premix of gas and air includes a burner head 26 comprising a plurality of perforated ceramic plaques 28. Each of the latter is associated with a metal baffle 30 presenting a lower apertured wall 32 which is spaced from the lower side of the plaque 28. A premix of gas and air is distributed evenly by a distribution baffle 42, then passes through the baffles 30 and through the perforations in the plaques 28. Each baffle 30 creates regions of different pressures of the gas and air mixture at the entry to the plaque 28 to establish both main flames and smaller retention flames on the burner head.

Title: Data switch
Inventor: JONES TREVOR
IPC: H04L49/111
Filed: 1998-05-11
Abstract: Multiple similar elements in a data switch, for example input or output ports 20a,b,c,d, are operated synchronously (even for essentially asynchronous data) at staggered timings. The staggering of the timings allows the number of control signals acquired to be reduced, as the elements can be identified to some extent from the time at which they are active. In a similar manner, signalling information such as buffer occupancy may be communicated using the timing of signalling to identify different elements.

Patent GB-2331184-A (GB)
Title: Thermally responsive switch
Inventor: TSUJI TAKAO
IPC: H01H37/54
Filed: 1998-11-04
Abstract: A thermally responsive switch includes a metal housing 2 formed into the shape of a bottomed cylinder and having an open end, a metal header plate 3 airtightly closing the open end and having a through hole 3B and an electrically conductive lead terminal pin 5 hermetically fixed in the hole by an insulating material 4, i.e. glass. A thermally responsive element 10 which may take the form of a shallow dish and may have a generally central through hole reverses and re-reverses in curvature in response to predetermined temperatures. A fixed contact 6 is provided on a portion of the lead terminal pin 5 in the hermetic housing 2. An elastic or flexible moveable plate 8, i.e a leaf spring, has one end secured to a moveable plate support 7 whilst exerting a biasing force at its other end against the moveable plate support 7. A moveable contact 9 which may be fixed to the moveable plate 8 engages and disengages from the fixed contact 9 when the thermally responsive element 10 drives the moveable plate 8. The moveable plate support 7, the moveable plate 8 and the thermally responsive element 10 may be integrally assembled to the header plate 3. Such an arrangement means that no current passes through the thermally responsive element 10 hence ensuring that its actuation is a result of ambient temperature rather than current variations.

Title: Spring probe for testing
Inventor: VINTHER GORDON A
IPC: H01L21/66
Filed: 1999-03-16
Abstract: A spring probe 10 comprises first 12 and second 18 probe section 35 each with a probe tip 26, 22. The sections 12, 18 move relative to one another under the bias of a spring 16 compressed between flanges 28, 24 of the respective sections 12, 18. The arrangement minimises the length of the probe 10. The length of the spring 16 when fully compressed may be greater than the length of the maximum stroke of the sections 12, 18 relative to one another. During assembly, a plunger 36 of section 12 may enter the open end 20 of a barrel of section 18; a spring may then surround the barrel; and the sections may be pressed together, causing a crimping surface 38 on section 12 to deform the end 20 of the barrel and thereby retain the plunger 36 against bias of the spring. Alternatively, the end barrel may be deformed inwards and resiliently deform when the plunger is being introduced, then return to trap the plunger against the spring bias. In a further alternative, plural probes may be mounted in plural mounts 100, figure 13, in which case, the barrel and plunger mechanism of the may be replaced by opposing semi-cylindrical bearings.

Title: Method for obtaining transgenic plants showing a modified fructan pattern
Inventor: SMEEKENS JOSEPHUS CHRISTIANUS
IPC: A23L29/244
Filed: 1993-12-28
Abstract: The present invention relates to a method for obtaining transgenic plants showing a modified fructan pattern as compared to non-transformed plants, comprising the steps of: a) preparing a DNA construct comprising one or more fructosyltransferase genes, or modified versions thereof, being operably linked to a promoter sequence active in plants and a terminator sequence active in plants; b) transforming a plant cell with the construct; and c) regenerating a transgenic plant from the transformed plant cell. Preferably, the 5' untranslated region of the fructosyltransferase gene is modified such that the expression of the fructosyltransferase is not negatively affected. The DNA construct may also comprise a targeting sequence upstream from the fructosyltransferase gene for directing the fructosyltransferase to a specific plant tissue or plant cell compartment. The fructosyltransferases produced in the transgenic plants change the fructan pattern of the plants, thus leading to different plant performance due to altered sink-source relations and yield, increased tolerance for drought, cold or other stresses, higher dry matter content, better taste and storability, and improved nutritional value. The plants are also suitable for use as raw material for fructan production.
