Patent GB-2221164-A (GB)
Title: Breathing apparatus
Inventor: EDWARDS DAVID BRIAN
IPC: A62B7/10
Filed: 1989-07-13
Abstract: A powered respirator comprises a motor-driven fan unit 11 drawing air through an upstream or downstream (Fig. 4, not shown) filter 16 for delivery to a facepiece 1. Operation of the fan motor 13 is controlled in response to a differential pressure sensor 17 tapped in across the fan unit so as to reduce the fan throughput in response to an increase in the pressure differential and to increase the fan throughput in response to a decrease in the pressure differential, and thereby match the delivery of air to the breathing demand of the wearer. The diaphragm 20 or other pressure-responsive member of the sensor 17 is isolated from unfiltered air and can therefore provide no leakage path for contaminants to the facepiece if ruptured. In the alternative embodiment (Fig. 4) with the positions of the fan and filter reversed so that the fan is upstream of the filter, but similarly controlled in response to the differential pressure across the fan, any contaminant which could pass through the pressure sensor is removed by the downstream filter before delivery to the facepiece.   <IMAGE>

Title: Prepayment commodity metering system
Inventor: CLARKE DAVID JOHN
IPC: G07F7/00
Filed: 1990-09-10
Abstract: A commodity metering system, particularly for metering electricity, comprises a credit meter having an optical port via which it can be reprogrammed and its readings of the amount of the commodity supplied can be accessed. To convert the meter into a prepayment metering system, a separate prepayment unit is connected to it by means of an optical link which is sealingly coupled to the optical port of the meter. The prepayment unit stores credit read from credit tokens, typically in the form of electronic keys, smart cards or magnetic cards, and periodically reads the meter via the optical link. When the monetary value of the amount of the commodity supplied equals the value of the credit stored, the prepayment unit cuts off the supply of the commodity. The prepayment unit also has an optical port, which communicates via the optical link with the optical port of the meter and via which the meter readings can be accessed and both the meter and the prepayment unit can be reprogrammed.

Title: Improvements in or relating to vibratable ring-like structures
Inventor: SANSOME DENNIS HUGH
IPC: B21C3/02
Filed: 1990-11-09
Abstract: A vibratable drawing die presenting a central, circular die orifice of mean radius A and a circular and coaxial outer surface of radius B, and having at least two radial projections 8 disposed symmetrically around the outer surface to which vibrators can be attached. Efficient transmission of energy from the vibrators to the wall of the die orifice is promoted by designing the die so that its imaginary circumference at its mid-radius - that is to say, a radius equal to the mean of the sum of A and B - equals n times the wavelength of the applied vibrations where n is a positive integer, and by dimensioning the arcuate width of each projection to half a wavelength. Examples of dies according to the invention having two, four and six projections are illustrated. The specification also teaches enhancing performance further, by equating certain other dimensions of the die to functions of the wavelength of the applied vibration. <IMAGE>

Patent GB-2246034-A (GB)
Title: Circuit and method for improved dimming of gas discharge lamps
Inventor: SULLIVAN CHARLES R
IPC: H05B41/285
Filed: 1990-12-12
Abstract: To ensure stable operation of a gas discharge lamp, particularly a compact fluorescent lamp, at light levels below about 40% of full light output, a current source has an output impedance of greater than about 5000 ohms. This may be provided by a purely resistive, capacitive or inductive element or a resonant LC circuit. Alternatively a resonant LC circuit may be driven by a variable AC voltage source in a current control feedback loop (Fig 4). To avoid striations when operating a compact fluorescent lamp at low output levels, it may be driven with a D.C. component combined with A.C. at a frequency greater than 20 KHz, the D.C. component being less than 5% of the nominal value of lamp current required to provide full light output (Figs 5, 8). Alternatively, high frequency A.C. (eg. 27 KHz) may be combined with a lower amplitude, lower frequency (30 Hz to 5KHz) A.C.component having a sine, square, a triangle or sawtooth waveform which may be asymmetrical (Figs 6, 7, 9). One source may comprise a pulse duration modulated inverter 9 in a current controlling feedback loop 11, 29, 30, 32 and driving a resonant LC circuit at a frequency (27 kHz) less than its peak response frequency (33 KHz) with a rectifier 15 providing a D.C. component. A current sensor 29 may have a dual slope characteristic giving high sensitivity at low current and low sensor power dissipation at high current, (Fig 12). <IMAGE>

Title: Ship powered by gas turbine engine has air intake in side of ship
Inventor: HATFIELD JOHN EDMOND
IPC: B63H21/16
Filed: 1991-02-20
Abstract: A twin-hulled ship (100) is powered by a gas turbine engine (116, 118) in each hull (102, 104 Fig 1b), the engine being located near the waterline in vertical alignment with a position outboard of the superstructure's internal sidewall (110, 112), but preferably inboard of the super-structure's external sidewall (106, 108). This is facilitated by the outward bulge of the hull (102, 104) relative to the superstructure's external sidewall (106, 108). An air inletfifter bank (124, 126) is mounted in the side of the superstructure sufficiently far above the waterline to avoid swamping. Air intake ducting (130, 131) leads from the filter bank (124, 126) to the engine (116, 118), and exhaust ducting (134, 136) leads from the engine to an exhaust outlet (138, 140) at a higher level than the filter bank (124, 126). This arrangement enables intrusion of intake and exhaust ducting into the main loading deck space (103) to be avoided while minimising deviation of intake and exhaust ducting from a straight line path. Preferably, to minimise spoiling of the lines of the ship's sides, the filter bank and the intake and exhaust ducting are housed entirely between the superstructure's internal and external sidewalls. <IMAGE>

The two forward legs are fixed to a main graduated frame 3 but the third leg can be moved accurately along this main frame and is associated with a vernier scaled cursor 4. For easy manipulation in situations of repetitive production the instrument can be scaled in groove numbers but its lower scale can be calibrated in terms of either metric or imperial measure. The moving parts of the gauge can be moved micrometrically and subsequently locked in position by screws 5 and 7 if desired. <IMAGE>
