Patent GB-2214771-A (GB)
Title: Optical fibre pressure or weight transducer
Inventor: PAUL GEORGE LANGE
IPC: G01G19/02
Filed: 1989-01-05
Abstract: A pressure or weight transducer comprises an optical fibre (10) which is located on a flat rigid surface (12). A constant light signal is fed into one end of the fibre from a control unit (13). The control unit (13) includes a receiver at the other end of the fibre which detects changes in the light transmission level and produces an output signal which is either calibrated to be proportional to the changes in pressure or weight applied to the fibre or to change from a first to second state in response to that pressure exceeding a predetermined threshold. The transducer may be used to count vehicles on a road, for weight measurement, and for burglar alarms. <IMAGE>

Title: Steam spray iron with separate water tank
Inventor: RAWLE STEPHEN LEONARD
IPC: D06F75/12
Filed: 1989-04-05
Abstract: An iron 1 has a spray nozzle 24 and steam jets. The iron receives water from a separate water tank 3 via a water feed tube 2. The spray generation is achieved by a manually operable water pressurising means 23, the back flow of the pressurised water being prevented by valve 26. The construction is such that when the iron is up-ended e.g. when temporarily not in use, steam generation is not possible because valve 14 blocks passage 11 and the level of water in chamber 10 is below the entry point to steam valve 13. <IMAGE>
Patent GB-2234078-A (GB)
Title: Analysis of waveforms
Inventor: HOLDSWORTH JOHN WILFRED
IPC: G10L25/27
Filed: 1989-05-18
Abstract: A waveform to be analysed is spectrally resolved into a plurality of frequency channel outputs (1). Amplitudes of the channel outputs are then compared with threshold values (4), with the threshold values being varied in dependence on 1) previous amplitude detection in the same channel (13, 14, 15) and 2) amplitude detection in adjacent channels (16). In this way features introduced by the spectral resolution of the waveform may be filtered out along with unwanted noise. In addition, smearing due to compression of the output of the spectral resolution may be counteracted. Hence, the present invention is particularly useful in the analysis of sound waves and in speech recognition systems.

Title: Glass melting furnace
Inventor: DULY RAYMOND KENNETH
IPC: C03B5/033
Filed: 1989-09-07
Abstract: A glass melting furnace comprises a base structure (6) defining a melting chamber (8) an intermediate chamber (10), and a working chamber (12), in which chambers heating means are located. An opening (22) is provided into the melting chamber (8), through which batch material may be deposited on the body of molten glass in the melting chamber. Glass flows from the melting chamber (8) through an outlet (26) at a lower part thereof, which opens into the intermediate chamber (10), and flows over a weir (30) from the intermediate chamber (10) into the working chamber. Located in the outer walls of the working chamber are working outlets (34), through which blowing irons or the like tools may be entered, for a manual withdrawal of molten glass from the chamber (12). The rate of production of molten glass by the melting chamber (8) is lower than the rate of utilisation, such that during a working shift the level of glass in the working chamber falls from a maximum level towards a minimum level, and outside the working shift (e.g. overnight) the level in the working chamber increases from the minumum level to a maximum level. Overflow ducts are provided, at locations which define the maximum level of glass in the working chamber i.e. a short distance below the locations of the working outlets (34).

Title: Catalyst material comprising platinum alloy supported on carbon
Inventor: BUCHANAN JEFFREY STUART
IPC: B01J23/64
Filed: 1990-03-21
Abstract: An eloctrocatalytic material comprises an alloy of platinum with another element, supported on a conductive carbon support, the metal area of the alloy being greater than 75 m<2>/gPt, and at a useful platinum loading, is especially suitable for use in phosphoric acid fuel cells, and demonstrates unexpectedly high stability at the high metal areas obtained. This material is produced by supplying a basic solution of compounds of platinum and one or more alloying elements onto the carbon support and reducing and heat treating the support carrying the compounds so as to form the platinum alloy. Suitable alloying elements are Ti, Or, Mn, Fe, 00, Ni, Cu, Zr and Mf. The catalyst may have a BET surface area of less than 1000m<2>/gm. The reduction may be carried out in the liquid phase by adding a reducing agent to the slurry after deposition; drying the slurry and then reducing using a gas phase reducing agent. Alternatively reduction and heat treatment may take place in a single step.

Title: Resonant cavity for NMR
Inventor: MANSFIELD PETER
IPC: G01R33/36
Filed: 1990-08-10
Abstract: A resonant array for use in NMR at high frequencies, e.g. 500 MHz or more, comprises two identical end structures 10 joined by a plurality of continuous electrically conductive rods 30 to form a plurality of pi or T electrical circuit sections, the rods also serving to space and support the end sections. As shown, the end sections are machined conductive plates and include clusters of slotted loop resonators 20, one plate being slidable on the rods to adjust the spacing l. Two concentric such plates may be provided at each end. The slotted loops may be formed or disposed in different manners, and have associated capacitors and guard rings. By stacking slightly staggered end plates loop inductance may be increased. Alternatively the end structure may comprise a segmented ring, or a non-conductive support on which are mounted discrete inductors or capacitors. The ends may be formed as half annuli to give a structure which cooperates with a conductive plate, giving easy access for the specimen. Adjacent rods functioning similarly may be joined in the form of a plate (Fig 18b). <IMAGE>

Title: Arrangement for testing the physical characteristics of coins
Inventor: SEHER ECKHARDT
IPC: G07D5/00
Filed: 1991-07-03
Abstract: The diameter of a coin 3 is detected by the use of two light emitters 1 and a light receiver 2. The two light emitters are clocked with different frequencies f1, f2 and the output of the light receiver applied to filter amplifiers 6,7 to separate the signal components. To determine the surface structure of the coin in addition to its diameter the coin is rotated by a motor M and a further light emitter 10 operated in a pulsed manner illuminates a portion of the rotating coin surface. A direct light receiver 11 and a scattered light receiver 16 produce outputs which are filtered by filter amplifiers 13,13' and used in combination to evaluate the coin surface structure by comparing it with known patterns. The combined diameter and surface testing system including the clocking and pulsing of the light emitters may be controlled by a micro-controller 9 which automatically aligns the clock frequencies of the emitters and controls their beam strength during idle running (ie no coin in path). The signals from the filter amplifiers are digitised by A/D converters (8,8' fig 4 and 13,13' fig 9) which may be integrated with the micro-controller in the signal processing circuit. <IMAGE>
