Patent GB-2195447-A (GB)
Title: Position sensing transducer
Inventor: ATKINSON JOHN KARL
IPC: G01P3/52
Filed: 1986-09-17
Abstract: A position-sensing transducer is a linearly variable differential transformer, which is mounted on a motor vehicle suspension damper. The transducer comprises a primary winding 20 movable relative to two secondary windings 22, 24 and a detector responsive to the difference between the magnetic coupling of the primary winding to the respective secondary windings to provide an indication of the relative position of the primary winding. In order to achieve output linearity, one secondary winding 24 overlies the other 22 and the number of turns in each winding per unit length tapers along the length of the winding, the direction of taper in one winding being the opposite of the direction of taper in the other. Provision of a primary winding which is movable relative to the two secondary windings is said to simplify construction. Current is driven through the transformer primary winding by a Colpitts oscillator. A pair of capacitors (52, 54 Fig. 2) in series with the primary winding form a series resonant circuit across the power supply. The oscillator frequency is 2 kHz. <IMAGE>

Title: Aircraft jet nozzle control apparatus.
Inventor: SEYFANG GEORGE REGINALD
IPC: B64C29/00
Filed: 1986-12-01
Abstract: Nozzle control apparatus for VSTOL aircraft power plant having at least one vectorable thrust nozzles 22 comprises powered means for effecting vectoring movement of the nozzles and oscillating means for oscillating the nozzles about at least one axis so as to enlarge the area 32 of a solid surface 12 affected by the exhaust gases 25, 26 from the nozzles 22 during hovering and/or landing. In the prior art, the hot jet 26 impinges on a relatively small area of the surface which area rapidly exhibits erosion effects; it has been found that the erosion is generally proportional to the local rate of heating, with a surface time constant of a few seconds. Accordingly, ground/deck erosion is alleviated by spreading out the jets 25, 26 and especially the hot jet 26 to increase their 'footprint', i.e. of the area 32. <IMAGE>

Patent GB-2192391-A (GB)
Title: Process for the production of an explosive
Inventor: HALLIDAY PIETER STEPHANUS JACO
IPC: C06B21/00
Filed: 1987-06-15
Abstract: In a process for the production of a 'water-in-fuel' or 'melt-in-fuel' emulsion explosive a density- reducing agent is introduced and dispersed in the emulsion at an elevated temperature whereat the emulsion is essentially liquid, the explosive is cartridged and then subsequently cooled by means of a refrigerated fluid so that the continuous phase solidifies and stabilises the dispersion of the density-reducing agent in the explosive. Preferably, when the density-reducing agent comprises gas bubbles the explosive is subjected to an elevated pressure before it is cartridged in order to ensure that the sensitivity of the explosive will not be impaired by disturbance of gas bubbles by any pressure drop which might occur during cartridging. The invention also extends to a cartridging machine for cartridging emulsion explosive, the machine comprising a container defining a sealed pressurizable explosives chamber which has an explosives inlet and at least one explosives outlet provided with a positive displacement pump for pumping explosive from the chamber into a cartridge.

Title: Viscosity reducing agent
Inventor: EVANS ROGER
IPC: A23G1/56
Filed: 1988-04-26
Abstract: A viscosity reducing agent for chocolate compositions is derived from oats by extraction thereof with a polar solvent, such as ethanol or propanol, followed by evaporation of the solvent until an oil (which is the viscosity reducing agent) separates out. The viscosity reducing agent has properties similar to soya lecithin. A viscosity reducing agent having properties similar to a PGPR-type emulsifier can be produced either by a pre-extraction of the oats with a non-polar solvent e.g. hexane, followed by the polar solvent extraction, or by an extraction of the polar solvent extract with methanol followed by evaporation of the latter.

Patent GB-2245443-A (GB)
Title: Signal digitiser
Inventor: ALCOCK ROBERT NICHOLAS
IPC: H03M1/18
Filed: 1990-06-22
Abstract: A digitiser is provided for measuring the amplitude of. for example, a radio frequency signal over an extended dynamic range. A radio frequency attenuator (2), switchable between predetermined attenuations, is connected in series before a radio frequency detector (0) to receive an input radio frequency signal on terminal (1) to be digitised. A switching signal (SD) is supplied to the attenuator to effect an increase in attenuation if the detected video signal input to an analogue to digital converter (10) exceeds a predetermined threshold level (VU). The increased attenuation is maintained while digitisation of the attenuated signal is effected. The switching signal (SD) and the digitised signal (D) are connected to combining means (16) to provide on an output (17) a digitised version of the input R.F. signal of wider dynamic range than that of the analogue to digital converter alone. Further threshold levels, each associated with a corresponding attenuation value, may be provided to yet further extend the dynamic range of the signal digitiser. <IMAGE>

Title: Electrostatic deflection of charged particles.
Inventor: RHODES PAUL MARTIN
IPC: B41J2/095
Filed: 1990-11-21
Abstract: A deflection arrangement for deflecting charged particles, e.g. ink drops in an ink jet printer, is arranged so that the potential dropped across an air gap between deflection electrodes varies with position along the air gap. This may be achieved by providing a varying thickness of dielectric material 31 on one deflection electrode 29, extending towards the other deflection electrode 27. Preferably, the width of the air gap varies to follow the fanning out of the paths of differently deflected particles (e.g. ink drops), and the variation in the potential across the air gap allows advantage to be taken of the fact that the dielectric strength (breakdown field strength) of air varies with the width of the air gap. <IMAGE>
Patent GB-2244890-A (GB)
Title: Trunked radio repeater system
Inventor: HUGHES III HOUSTON HOWARD
IPC: H04L1/16
Filed: 1991-05-24
Abstract: A digitally trunked radio repeater system providing improvements in timeliness of channel acquisition and channel drop, and in reliability of critical control signalling, uses a high digital signalling rate of 9600 b.p.s. and uses a control channel to convey digital channel request and assignment messages between the central site 100 and mobile transceivers. The mobile radio transceivers transmit channel requests on the control channel and if no response is received, the mobile retries during a retry time window which increases in duration in dependence on the number of retries. The calling mobile and called mobile(s) switch to a working channel in response to an assignment message received on the control channel. Subsequently, in response to an assignment confirmation signal sent from site 100 on the working channel, the calling mobile sends an acknowledgment signal on the working channel and then site 100 sends an unmute message. Subaudible digital signals transmitted on the control channel and on active working channels allow late entry, shifting to higher priority calls, and other advanced functions. Message and transmission trunking capabilities are both present so as to maximize working channel usage without compromising channel access for high priority communications. During transmission trunking, called and calling transceivers return to the control channel after each transmission (and called transceivers may be inhibited from transmitting) but grant higher priority to calls from the other transceivers being communicated with to ensure continuity over an entire conversation. <IMAGE>
