Title: Lighters/bottle openers
Inventor: PEDERSEN HENNING STOUGAARD
IPC: F23Q2/32
Filed: 1984-03-09
Abstract: A pocket lighter is shaped with a bottom portion having a projection (3) of reduced cross sectional area so as to be usable as a pipe stopper. The projection is shaped as an undercut hook member, whereby the lighter is additionally usable as a crown cork opener. Instead of the pocket lighter itself being provided with the hook projection (3) this projection may be provided bottomwise on a casing member (1) operable to receive the combined fuel tank and handle portion (13) of a standard lighter of the disposable type. The hook member (3) as made of plastics may have a metallic strip insert (15), the outer end (14, 16) of which is either surface reinforcing for the crown cork edge engaging surface portion of the hook member (3) or is projecting from this surface portion so as to be extra safely engageable with the inside of the crown cork edge portion.

Title: Tyre Pressure Sensing System
Inventor: LUKE DOUGLAS VERNON
IPC: H04B10/00
Filed: 1984-03-13
Abstract: A tyre pressure sensing system has a sensor 21, mounted on the tyre hub 2, and connected to a fibre-optic cable 23. The end of the cable is mounted coaxially of the tyre 1 in alignment with a stationary cable and light is transmitted across the rotating interface. The cable has an inner bundle of fibres (300) and an outer ring of fibres (302) which extend to a radiation source (31) and to a detector (32) respectively. The source 31 supplies radiation, via the cable, to the sensor 21. Change in tyre pressure moves a mask (218) in the sensor, thereby changing the amount of radiation transmitted from one bundle of fibres to the other. The detector monitors the radiation and provides an output 50 indicative of tyre pressure. Wheel speed can also be measured (Fig. 5) by detection of a bar code (513) rotating with respect to sensor 510. The bar code also serves to identify the wheel. <IMAGE>

Title: Bird deterrent
Inventor: GRAY JOHN
IPC: A01M29/32
Filed: 1985-02-19
Abstract: A bird deterrent (1) is mounted on each top edge of a four-sided litter bin (2). The device (1) comprises a plurality of spheres (10), each of which is freely rotatable upon a common spindle (8), which in turn is mounted on the litter bin (2) by a pair of supports (3). When a bird tries to land on any one or more of the spheres (10), the respective sphere(s) will immediately rotate, thus giving the bird a sense of imbalance, and causing it to fly away. The arrangement of the device (1) is such that the supports (3) do not afford any significant, immovable perching surface for a bird. Bird deterrent devices such as that illustrated may be employed on other ledges. <IMAGE>

Title: Disengageable drive and electric power pack for bicycle
Inventor: DANKS BRIAN COLIN
IPC: B62M13/04
Filed: 1986-02-06
Abstract: A bracket 10 is secured to bicycle seat stays 12 next to the seat tube 14. A drive assembly 20, comprising an electric motor 26 and drive roller 28, depends from a pin 22 on the bracket to enable the drive roller to be swung rearwardly into drive-transmitting engagement with the rear wheel 24 of the bicycle. The geometry of the arrangement is such that the torque on the drive roller tends to maintain the roller 28 in engagement with the wheel 24, but as the road speed increases so does the tendency for the roller to be thrown forwardly and the drive disengaged. Drive can be engaged initially by means of a cable control 40 to a rocking lever 36 which acts on a stud 44 of the drive assembly 20. <IMAGE>

Title: Medium for the production of viable fused cells
Inventor: ZIMMERMANN ULRICH
IPC: C12N15/04
Filed: 1985-10-11
Abstract: In order for a medium for the production of viable, fused cells by means of field-induced electrical fusion, particularly for the production of hybridoma cells, whereby the medium comprises an approximately isotonic, aqueous solution of electrolytes and non-electrolytes with a maximum ionic strength of 0.1, said solution containing calcium and magnesium salts, to be improved to such an extent that it adapts the fusion conditions of differently sized cells to each other during the field pulse and additionally allows closer cellular membrane contact through alteration in the structure of the medium in the region of the cellular membranes, so, that fusion can be performed with a high yield and under mild conditions and at the same time the survival rate of the cells is very high, the ratio of concentration of calcium and magnesium ions is in the range between 1:2 and 1:10 and the ionic strength of the solution is adjusted for optimum membrane contact through variation of the electrolyte concentration, whereby corresponding to a change of the electrolyte concentration is a complementary change of the non-electrolyte concentration, such that the isotonic property of the solution is constantly guaranteed by the overall osmolarity of the electrolyte and non-electrolyte parts.

Title: Control of heating or cooling
Inventor: LAWRENCE JOHN MICHAEL WALMSLEY
IPC: F25B49/02
Filed: 1987-07-29
Abstract: A method of controlling a compressor driven vapour compression heat movement system, e.g. a refrigeration system, air conditioning system or heat pump, in which a common compressor system heats or cools a plurality of load units and is operated in cycles each of which include a compressor system higher capacity period and a compressor system lower capacity period, is characterised in that the lower capacity period is made or controlled to be sufficiently long that when the compressor system is switched to the higher capacity a majority of the load units are demanding heating or cooling and that the higher capacity period is made sufficiently long that when the compressor system is switched to lower capacity one or more of the load units have had their heating or cooling demand satisfied. The length of the lower capacity period may be controlled in response to the length of the preceding higher capacity period. The higher capacity period may be terminated when the load on the compressor system falls below a set point which may be adjustable. The load may be inferred from the compressor inlet pressure or from current consumption, power consumption or power factor.
