IPC: H01H36/02
Filed: 1987-10-19
Abstract: A flow-sensitive switch comprises a body 1 defining a flow chamber 2, a spout 11 mounted within the chamber 2 to leave a free space 12 around the spout 11, and a control member 14 arranged and guided for longitudinal movement within the chamber 2.

Patent GB-2208657-A (GB)
Title: Thin film alloying
Inventor: EVANS ANTHONY CYRIL
IPC: C23C14/50
Filed: 1988-08-10
Abstract: A method of depositing material on a substrate from a plurality of sources each having a deposition axis comprises arranging the sources S1, S2, S3, with their deposition axes A1, A2, A3 parallel and spaced around a circle C1 of radius R whose plane is normal to the parallel axes, causing relative rotation of the substrate and said sources about a rotation axis parallel to said axes at a radius equal to the radius of said circle, and controlling the speed of rotation and outputs of said sources so that less than a monolayer is deposited on the substrate as it makes one pass relative to one source. The source may be a sputtering target, a magnetron, an electron beam heated hearth, a filament source, or an electrically heated boat. In particular there are a plurality of substrates, each being mounted about the same axis at the same radius for movement relative to said sources. As illustrated in the Fig. the outputs of each source spaced out from the deposition axis 6 deposit material uniformly over circles C4, C5, C6, on disc D. The circles C4, C5, and C6 have their centres lying on circle C2 of radius R on disc D coaxial with C1. As the disc D rotates, the substrates pass through the circles and receive deposits of material from the sources. The rates of deposition and rotation are governed so that more than one revolution of the disc is required to build up a complete monolayer on a substrate. This ensures an even formation of an alloy from the sources. <IMAGE>

IPC: A61M16/04
Filed: 1988-08-12
Abstract: An endotracheal tube (10) has a tapering end portion formed with a port (18) and defining a small diameter orifice (16). To insert the tube (10), a pilot member such as a fibroptic endoscope is first passed through the body portion (12) and orifice (18) before being negotiated down the patient's tracheo-bronchial tree. The tube (10) is then easily slid down the inserted pilot member which is subsequently withdrawn. Alternative means of locating the end of the endotracheal tube relative to the pilot member and of allowing the passage of gases are disclosed.

Patent GB-2212790-A (GB)
Title: Improvements in or relating to flow control valves
Inventor: MARTIN DAVID
IPC: B65G53/22
Filed: 1988-11-23
Abstract: The disclosure relates to a powder flow control valve comprising a nozzle (33) formed from a material such as high density polythene having an upper frusto-conical section (33a) which converges towards the lower end of the nozzle and terminates in a cylindrical section (33b). The nozzle is encircled by a plenum chamber (24) to which sources of vacuum and air pressure are selectively connectable through a pneumatic control system (14). When vacuum is connected to the plenum chamber, the resulting pressure drop across the wall of the porous nozzle causes powder flowing through the nozzle to consolidate in the nozzle and terminate the flow. When air pressure is applied to the plenum chamber, the resulting pressure rise across the boundary surface accelerates powder flow through the nozzle. The control means is arranged to establish air pressure in the plenum chamber to initiate opening of the valve and flow through the valve and, after a pre-determined time, to terminate the air pressure supply and allow powder to flow under gravity through the nozzle before flow is terminated when a pre-determined quantity of powder has been delivered by the nozzle by applying vacuum to the plenum chamber.
Patent GB-2218239-A (GB)
Title: Label carrying encoded data
Inventor: CHANDLER DONALD GORDON
IPC: G06K7/00
Filed: 1989-04-07
Abstract: An optically readable label (30) stores encoded information in the form of a data array of a multiplicity of information-encoded hexagons (20) contiguously arranged in a honeycomb pattern, and having at least two different optical properties (e.g. black and white). A process for encoding information in the optically-readable data array comprised of a honeycomb of contiguous hexagons (20) encoded by assigning optical properties to individual hexagons in a predetermined pattern consists of ordering the hexagons (20) in a predetermined sequence, and printing the hexagons (20) with at least two optical properties (e.g. black and white). A process for retrieving information by optically scanning the information-encoded data array of contiguous polygons, preferably hexagons (20), comprises creating an optical replica of the digital bit stream representative of the optical properties of the information encoded polygons, decoding that optical replica and retrieving the decoded bit stream.

Patent GB-2223320-A (GB)
Title: Capacitance measuring
Inventor: BINNIE ALEXANDER J
IPC: G01R27/26
Filed: 1989-09-26
Abstract: Measurement of line capacitance, eg. of a telephone line, is performed using a known capacitance (6) in series with the line conductors (8). An oscillatory signal (1-4) is input (5) to the conductors through the known capacitance (6) and an output current signal is obtained (7b) that is dependent on the line capacitance. After passing the output through amplifying (10) and phase sensing (11) stages the output signal in phase with the input is obtained and is scaled (12) to drive (13) a meter (14). In Fig. 2 (not shown) an output voltage signal from the line conductors is used to determine line capacitance. <IMAGE>

Title: Optical waveguide taper having core, interlayer and cladding
Inventor: WILSON STEPHEN JOHN
IPC: G02B6/26
Filed: 1989-11-17
Abstract: An optical waveguide adiabatic taper includes an interlayer 32 between its optical core 30 and its optical cladding 31 in order to "square-off" the optical field profile at the larger end of the taper while leaving the profile at the smaller end substantially unchanged. This finds particular application as a component of a 1 x N single mode coupler. The smaller end of the taper can make a low-loss coupling with a single single mode fibre input, and the larger end will distribute the available power more evenly between the members of a close-packed array of N single mode output fibres than would be the case in the absence of the interlayer 32. The refractive index of the interlayer 32 is greater than that of the core 30 whose refractive index is greater than that of the cladding 31. <IMAGE>

Title: Controlling playback of a recording medium
Inventor: WOO JONG-SAM
IPC: G11B27/10
Filed: 1990-09-10
Abstract: A method of controlling playback of a recording medium comprises skipping an unrecorded area during playback of the recording medium in order to minimize the interruption time upon playing back a recorded program in a tape drive. The method is performed in such a way that while playing back a recording medium, an area with no video or audio signals recorded is played back at a high speed and an area with video or audio signals recorded is played back at a normal speed, to result in minimized time for playing back unrecorded areas. In addition, a power saving is achieved by automatically switching power-off when the recording medium playback is completed.

Title: Monitoring flow resistance
Inventor: ABSOLON ERIC WILLIAM
IPC: B01D37/04
Filed: 1991-02-11
Abstract: Flow resistance through a filter 2 is monitored by a differential pressure gauge 4, but the pressure actually applied, to the downstream or upstream side of the gauge, is automatically adjusted as the flow rate through the filter falls, so that the gauge always registers a value corresponding to the full rated flow rate of the filter. In Fig. 1 the pressure downstream of the filter is applied to side 12 of the gauge through duct 38 and disc 22, which is also urged upwards into space 18, to increase the pressure, by a lever 24 whose other end is pushed down by a diaphragm 20 loaded with full upstream pressure. The fulcrum Point 26 of the lever is adjusted by deflection of vane 36 in proportion to the flow rate. In Fig. 2 the pressure upstream of the gauge is adjusted by a bleed valve controlled by a venturi flowmeter. <IMAGE>
