Patent GB-2171296-A (GB)
Title: Interdental toothbrush
Inventor: TARRSON EMANUEL B
IPC: A46B17/04
Filed: 1986-02-18
Abstract: An interdental toothbrush has a handle (20) made from a mixture of a thermoplastic elastomer and a general purpose polypropylene. A twisted wire brush (26) projects from the handle in axial alignment therewith. The toothbrush can be held within a loosely clasped fist, with one end of the brush held between a thumb and an index finger. By manipulating the thumb and index fingers, the angle at which the brush projects may be changed at will. In this way, the insertion of the brush in more difficult to reach spaces in or around teeth is more easily performed. <IMAGE>

Title: Stairlift
Inventor: STOPHER ANTONY
IPC: B66B9/08
Filed: 1986-12-17
Abstract: A stairlift to enable elderly or infirm persons to travel safely on a flight of stairs comprises a seat (12), Fig.1 mounted on a carrier (10) adapted to travel on a rack-and-pinion arrangement (14,36) up and down a trackway on a flight of stairs.

Title: Eprom cell with integral select transistor
Inventor: TAM SIMON M
IPC: H01L21/336
Filed: 1988-01-08
Abstract: In an electrically programmable and electrically floating gate memory device, in the n-channel embodiment, a boron region (20a) is formed adjacent to the drain region (18a) under the control gate (14a) and extends slightly under the floating gate (12a). This region is formed using a spacer defined with an anisotropic etching step and, in addition to providing enhanced programing, prevents conduction when over-erasing has occurred, that is, when the erasing causes the cell to be depletion-like. The source region (16a) may extend deeper into the body of the device than the drain region (18a). <IMAGE>
Patent GB-2201307-A (GB)
Title: Electronic starter for discharge lamps
Inventor: MARTIN DAVID JOHN
IPC: H05B41/04
Filed: 1988-02-12
Abstract: A starter circuit for a gas discharge lamp T, particularly fluorescent lamps with heated cathodes, uses a thyristor-type of electronic starter switch device F having a high holding current and which can be made to drop out of conduction at current below the holding value by grounding the gate terminal G. The grounding is controlled by a switch TR2 connected to the cathode K of the device through a delay circuit R4, C2. The cathode circuit includes a current sensing resistor R3, such that during an A. C. supply half-cycle the device F reacts with the switch TR2 and ballast L to provide a multiplicity of ignition pulses for the lamp T using the drop out mode of device F. To initially heat the cathodes before ignition the device F is used as an ordinary thyristor. A delay circuit C1, R5 provides a preheating period by delaying operation of the switch TR2 to prevent initiation of the drop out mode. A circuit R7, C1 is provided to ensure that circuit operation is terminated if the lamp T fails to strike. The cathode heating phase may alternatively be provided by making the sensing resistor R3 a PTC type, such as a filament lamp, so that the switch TR2 cannot close until the resistor has heated up, (Fig. 8) <IMAGE>

Patent GB-2223562-A (GB)
Title: Monitor system for underfeed stoker
Inventor: MAY DAVID
IPC: F23K3/14
Filed: 1988-08-25
Abstract: The supply of solid fuel to a furnace 10 by an underfeed stoker 30 is monitored by the detection of a failure in the solid fuel supply system thereby ensuring that the furnace can be shut down, if the supply of fuel can not be maintained, to prevent damage to the furnace. Shearing of pin 78 on jamming of pick-up screw 80 results in member 76 becoming stationary, and is detected by an associated sensor. Exhaustion of fuel supply causes pick-up screw 80 to rotate excessively fast, and is detected by the same sensor. Preferably the sensor is an inductive proximity switch detector, and is triggered by a ferromagnetic body on member 76. <IMAGE>

Abstract: A fuel delivery system for automotive engine and like applications comprises a canister (12) for positioning within a fuel tank (18) having a lower end with a fuel opening and an internal wall (36) spaced from such lower end dividing the canister into the upper and lower fuel chambers. An electric-motor fuel pump (44) is positioned within the upper chamber and has a fuel inlet (46), a primary fuel outlet (48) for feeding high-volume fuel under pressure to an engine or the like, and a secondary outlet (50) for likewise supplying fuel under pressure at smaller volume than the primary outlet (48).

Title: Radio / sonic transponder location system
Inventor: TAYLOR WILLIAM STUART HICKIE
IPC: G01S13/86
Filed: 1990-04-09
Abstract: A radio sonic location system where a central unit Fig 1 sends coded radio signals to three transponders located at predetermined positions x, y, ... x3 y3. The transponders, when selected, send out a high frequency audio pulse covering the area that the central unit is located. The central unit measures the elapsed times from the initial radio signal to receiving the audio pulse from the transponders and converts this by computation to distances d1... d 3. The three distance measurements from three known locations of the transponders are converted by computer 5 to give a positional location x4y4 of the central unit in relation to the transponders. By measuring the audio pulse strengths in a set of directional microphones (Fig 4) on the central unit and calculating a proportional strength pattern with the known directional receiving characteristics of the microphones a directional facility of limited accuracy is also available for the central unit in relation to the transponders. <IMAGE>

Title: Detection of the susceptibility to scrapie
Inventor: HOPE JAMES
IPC: C12Q1/6827
Filed: 1990-11-01
Abstract: It has been found that there are at least three polymorphic sites in the gene for PrP (the ''prion protein'') which are linked to the susceptibility of a bovine or ovine animal (especially a sheep) to scrapie (also known, in cattle, as bovine spongiform encephalopathy). In the non-coding 5' region, two such polymorphisms govern cleavage by EcoRI and HindIII respectively, and in the coding region, the third polymorphism changes codon 171 from CGG to CAG (arginine to glutamine). These polymorphisms can be detected by conventional assays using EcoRI, and HindIII, or equivalent enzymes, followed by a Southern blot; DNA sequence analysis, for example with PCR methods; or peptide sequence analysis.

Title: Lock security in early/late gate synchronisation PLL
Inventor: VILHELMSEN TOM
IPC: H03L7/085
Filed: 1990-12-20
Abstract: A phase locked loop (PLL) is provided comprising a signal input, a clock for providing a clocked signal and a phase comparator for comparing the phases of an incoming signal at the signal input and the clocked signal. When the PLL is in a locked state the clocked signal is shifted by phase shifts in opposite directions to maintain the PLL in the locked state, but when in an out-of-lock state, the clocked signal is repeatedly shifted by a phase shift in one direction until the PLL is detected to be in the looked state. The first time the PLL is in the "out of lock" state a decision will be taken as to the direction of phase change to be made, and it is not possible to change the direction until the PLL is back in the in-lock state. 'In lock' may be defined as a phase difference greater than -90 DEG  but less than 90 DEG , and a flow diagram of the decision process may be provided. The PLL may lock to a frequency at least four times that of the incoming signal with a divider provided in the loop. The loop provides security of locking. <IMAGE>
