Patent GB-2183113-A (GB)
Title: Failsafe electrical power supply
Inventor: GLEDHILL GEOFFREY PETER
IPC: B61L1/20
Filed: 1986-09-09
Abstract: An electrical power supply unit includes a cyclically-operating input stage (15) which, when fed with one or more periodic control waveforms, is operative to produce a d.c. voltage of opposite polarity to that used to power the supply unit as a whole. This d.c. voltage powers a control circuit (16) which generates a cyclically-varying drive signal used to drive a dynamic output circuit (17) of the supply unit. In the absence of the control waveforms, input stage (15) fails to produce the d.c. voltage and control circuit (16) is therefore unable to generate the drive signal; as a result, output circuit (17) ceases to function. To provide rapid cut- off of the drive signal, a duplicated semiconductor switch arrangement (70) is connected between a line carrying the drive signal and ground. Correct functioning of the switches is checked by operating each in turn and monitoring the power supply output for the expected dip in the output voltage by means of a duplicated dip detector (71). <IMAGE>

Patent GB-2185609-A (GB)
Title: Gas-fired heating appliance
Inventor: CHESWORTH ARTHUR
IPC: F23D14/72
Filed: 1987-01-15
Abstract: A burner bar 11 having an injector 14 provides flames 12. A flame-failure device 17 cuts off the gas supply when it detects the absence of a flame. If the oxygen supply is inadequate, then the flames tend to lift off the bar as shown at 20, at the end distant from the flame-failure device. A flame lift-off device 22 detects the flame lift-off and shuts off a combustion air fan 16. This drastically reduces the air supply, causing lift-off all along the bar and causing flame-failure device to close the gas valve. Thus a single gas valve is used to cut off gas supply when either absence of flame or the beginning of flame lift-off is detected. <IMAGE>

IPC: H01L41/087
Filed: 1987-05-27
Abstract: A piezoelectric coaxial cable is made from a wire 8 comprising a central stretchable electrical conductor, preferably formed from a low melting point metal alloy, and an insulating surrounding layer, preferably formed from a vinylidene fluoride polymer. The wire is passed through a heating zone 12 and then stretched radially polarized at 14 to render the insulating layer piezoelectric. An outer electrical conductor is then provided. The insulating layer has a ratio R of its internal radius to its external radius which is preferably not more than 0.5 and especially not more than 0.4.

Patent GB-2219393-A (GB)
Title: Measuring a variable using interferometry
Inventor: BREARLEY MARTIN ALAN
IPC: G01B9/02
Filed: 1989-03-14
Abstract: A variable such as pressure or expansion is converted into displacement if an optical wedge 4 along a direction A-A coincident with a wedge face 14. The path for light reflected from the other wedge face 16 varies linearly with displacement and is measured interferometrically against reference light reflected from the surface 14. The arrangement may avoid susceptibility to external influences such as temperature pressure and vibration, for example by matching the wedge expansion with temperature against its change in refractive index. As shown splitter 3 (which may be a Wollaston prism) acts on laser light from fibre 2 and recombines interfering beams a and b for transmission to quadrature detectors 10, 11. The surfaces 14 and 16 of the wedge 4 (which may be filled with liquid) may be partially and fully reflective respectively, or that part of surface 14 reflecting the reference beam may be fully reflective (Fig 7). The reflective surfaces may be separate from the wedge (Fig 5). Wedge 5 corrects for path differences across the beam width. <IMAGE>

Abstract: 904,879. Accounting-machines. NATIONAL CASH REGISTER CO. Feb. 6, 1961 [Feb. 17, 1960], No. 5562/61. Divided out of 907,591. Drawings to Specification. Class 106 (1). In an accounting machine with a plurality of totalizers, an overdraft conversion mechanism rendered effective when an overdrawn totalizer is selected for a total-taking operation causes the machine to perform two cycles of operation, during the first of which the overdraft in complementary form is transferred to a set of normally engaged overdraft wheels while the actuators re-set the overdrawn totalizer, the overdraft wheels then being disengaged, and during the second of which the actuators drive the overdraft wheels further in the same direction to their zero positions, and are thereby set to the difference between the complementary overdraft and zero, the machine also including a correcting device effective after the disengagement of the overdraftwheels in the first cycle and wherever an overdraft wheel has been moved from its zero position to advance the next higher order overdraft wheel by one step so that the actuators are finally set to the true negative total. The machine described is fully disclosed in Specification 907,591. Specifications 680,992 and 772,170 also are referred to.
