Patent GB-2234353-A (GB)
Title: Incipient failure detector
Inventor: BEAUMONT JAMES ORMOND
IPC: G07C3/00
Filed: 1989-07-28
Abstract: An apparatus provides warning of incipient failure of a physical system so as to allow corrective action to be taken to avoid serious failure. Indices of failure imminence are calculated, base upon measurements of system forcing functions and system responses. The calculated indices may be modified to allow for the effects of system operational parameters which are also measured. Said indices may be communicated to a human operator, or may be used directly to initiate corrective action. A specific example is given of the application of the apparatus to detecting imminent failure of the skin of an aircraft, using sensors measuring the difference between internal and external pressure (the forcing function) and strain gauges, vibration sensors etc. to detect the response. <IMAGE>

Title: Fuel filler cap arrangement
Inventor: PARDY RONALD
IPC: B60K15/04
Filed: 1989-12-12
Abstract: In a fuel filler cap arrangement the cap 14 has a body 18 and a head 16. In normal conditions, the head is secured flush with the surrounding vehicle bodywork 10 by means which are releasable to allow movement of the cap head from its flush position to a projecting position whereafter the head 16 can be gripped and turned to remove the body 18 from the filler pipe 12. Spring-loading may bring the head to its projecting position when it is released by the security means, which may be a key-operated device or a remotely-operably spring-loaded latch. Engagement between the cap and head may include a one-way ratchet mechanism which slips above a preset torque to prevent overtightening. <IMAGE>

Patent GB-2244393-A (GB)
Title: Electrical surface heating
Inventor: ASPDEN HAROLD
IPC: F24D13/02
Filed: 1990-02-07
Abstract: Harmful effects in the bloodstream and body cells owing to cyclotron resonance caused by alternating currents in surface heating appliances are reduced by so powering an appliance that a direct current component is continuously changing and/or the fundamental A.C. power frequency is eliminated. An underfloor heater or electric blanket may be energised by fully smoothed D.C. derived from A.C. mains, or by full-wave rectifying the A.C. supply without smoothing. A steadily changing current may be produced due to the increase in element resistance on heating, there being an automatic switch to cut off power before an equilibrium state is reached. A blanket may have elements 20 to 23 arranged in a bridge with SCR's 27, 28 shunted by resistors 29. The elements have different characteristics such that at low temperature elements 20, 21 have the greater resistance, whereas above a certain temperature elements 22, 23 have the greater resistance. If on initial closure of switch 25, SCR 27 turns on first this shunts its associated resistor 29 to keep SCR 28 off. As elements 20, 22 heat up the changing potential at SCR 27 eventually turns diode 30 on to trigger SCR 28 resulting in SCR 27 turning off, thus giving an astable operation with continuously changing heater current. <IMAGE>

Title: A revolution counting system
Inventor: PYE JOHN ALBERT
IPC: G01C22/02
Filed: 1990-03-28
Abstract: A revolution counting system comprises a counter unit fixed to a hub of a trailer wheel and a reader unit 14. The counter unit 1 has an electronic memory which stores the distance travelled by the trailer. Upon interrogation, the distance travelled is transmitted to the reader unit 14 where it is displayed on display 15 which, because it is part of the reader unit 14, is less susceptible to obscuration by dirt than would be the case if it were mounted on the counter unit. The transmission may be by radio using a transponder in the counter unit 1, responding to an initiating signal from the reader unit 14. The transmitted information may include data identifying the counter unit, the reader being capable of reading and storing data relating to many counters for subsequent transmission to a vehicle fleet monitoring computer. The reader unit may be hand-held, as shown, or fixed in a vehicle depot or rail waggon yard. A counter unit is described having a backplate 5 which rotates with the wheel and carries a disc 9 with the electronic circuitry and power and signal generating coils. The coils pass through the field of a magnet 8 on an arm 7 which hangs freely in a bearing 6. <IMAGE>

Title: Coin discrimination apparatus
Inventor: HUTTON LES
IPC: G07D5/08

Title: An amplification assay for hydrolase enzymes
Inventor: RABIN BRIAN ROBERT
IPC: G01N33/533
Filed: 1991-02-01
Abstract: Hydrolase enzymes are sensitively determined using substituted FAD substrates that are hydrolysed to form FAD, combining the FAD with an apoenzyme, and using the resulting holoenzyme to initiate a reaction leading to a detectable product. In a preferred embodiment the hydrolase is a phosphatase and the substrate a phosphorylated derivative of FAD. Preferred apoenzymes are apo-glucose oxidase and apo-D-aminoacid oxidase. The former gives exceptional sensitivity and the latter is suitable for use in a ''single pot'' assay system. The substituted FAD substrates, including phosphorylated FAD compounds, are considered to be novel compounds per se.

Title: Preventing dust adhesion in a furnace
Inventor: OKUNO SATOSHI
IPC: F27D25/00
Filed: 1992-05-22
Abstract: A portion of a furnace or combustion apparatus to which dust might otherwise adhere is made of a porous refractory material and air or gas is injected into the furnace through the pores. In a melting furnace, refractory porous members (108a, 108b) may provide the ceiling of a slag separating chamber and the inlet of an exhaust gas duct. The porous members are spaced from outer casings (105a 105b) so that cooling air or gas fed into the spaces is forced through the pores in the porous members. A porous member may extend around the periphery of a liquid injection nozzle, eg so that air or gas fed into the cooling chamber of an incinerator through the porous member inside prevents flower from accumulating at the tip end of the nozzle, attenuates the wake of the injected liquid and suppresses entrainment of dust in the liquid. <IMAGE>
