Title: Improvements in or relating to loading and unloading installations for horizontal strata bunkers
Inventor: COOK DOUGLAS RAYMOND
IPC: E21D9/12
Filed: 1984-02-23
Abstract: For the purpose of loading and unloading minerals into and from a horizontal strata bunker in a mine roadway a loading and unloading installation comprises an infeed conveyor 10 for conveying material into the bunker, a plough 14 movable longitudinally of the infeed conveyor to discharge material from the conveyor into a heap alongside it, an outfeed conveyor 17 extending substantially parallel to the infeed conveyor, a reclaiming machine 16 for transferring material from the heap to the outfeed conveyor, and haulage means for moving the reclaiming machine longitudinally with respect to the conveyor.

Patent GB-2158938-A (GB)
Title: Testing of pellets
Inventor: RICE THOMAS GERARD
IPC: G01B11/26
Filed: 1984-05-14
Abstract: Apparatus for testing the orientation of an end face of a pellet to the pellet axis includes a laser 13 which sends a beam 14 of radiation through a beam splitter 16 to apparatus 15. In the apparatus 15 a pellet has a mirror held to an end face and the radiation is reflected by the mirror to form beam 22 leading to sensor 26. If the end face is not at right angles to the pellet axis, the reflected beam is angularly displaced from beam 14, 14a and the beam 22 is divergent, to provide an indication at the sensor. A circular aperture 23 may cut off the beam 22 from sensor 26 at a predetermined angle of divergence to provide an indication of when the pellet end face is at a limit of acceptable orientation. The predetermined angle can be adjusted by changing the aperture diameter. A disc can replace the aperture. <IMAGE>

Title: Infra-red filter
Inventor: BREWSTER ARTHUR EDWARD
IPC: G02B7/00
Filed: 1985-01-04
Abstract: In our Patent No. 1050561 we have described in a gas analyser in which a light beam is passed via an oscillating filter to a gas cell from which it passes to a photodetector, the filter is oscillated so that the light wavelength leaving it varies in such a way that if the gas to be detected is present, the photodetector receives a varying current. In this, light reflected from a highly reflective face on the filter (3) or its carrier is used to power the oscillations. The filter may have a light absorbing portion (4) which flexes when heated by the reflected, incident light, or which may be ferromagnetic (see Fig. 4 - not shown) & heated above the Curie point to cooperate with stationary magnets to produce the oscillations. <IMAGE>
Patent GB-2171328-A (GB)
Title: Gas chromatography
Inventor: BUFFHAM DR JOHN AUSTIN
IPC: G01N30/46
Filed: 1985-01-07
Abstract: In method for gas chromatography, analysis is by measuring changes in the amount of absorbed gas in the column. In analytical apparatus, carrier gas passes through tubes 1 and 2 containing absorbent material and through capillary restrictors 4 and 5. Sample to be analysed is injected into carrier gas entering tube 1. Transducer 6 monitors changes in pressure difference between restrictor entrances and hence changes in flow rate and amount of absorbed gas in tube 1. Areas on trace of flow rate differences recorded by chart recorder 7 give sample analysis as gas volumes. New method can be used simultaneously with conventional method using composition detector 3.   <IMAGE>

Patent GB-2177491-A (GB)
Title: Gas fired heating appliance
Inventor: FORD GRAHAM
IPC: F23N5/02
Filed: 1985-05-24
Abstract: The appliance, e.g. a domestic space heater, incorporates a safety stem comprising a pilot (12) and a thermally sensitive element (10) which is arranged in normal use to be used by a flame issuing from the pilot (12) and which is operatively connected to a main valve (11) disposed in the main gas supply line of the appliance so that said valve (11) will remain open only when said thermally sensitive element (10) is sufficiently heated by said pilot (12). The pilot (12) is connected to a supply of gas by a further valve (12, 23, 24, 25, 26, 27) disposed upstream of the pilot (12) and which is resiliently biassed so as to reduce the flow of gas to the pilot (12) if the pressure of the gas supply falls below a predetermined minimum. The pilot (12) is so positioned relative to the thermally sensitive element (10) that the flame which in use issues from said pilot (12) will only be directed in a direction which will result in said thermally sensitive element (10) being heated sufficiently to maintain said main valve (11) in an open position if the pressure of said gas supply does not fall below said predetermined minimum. <IMAGE>

Title: A process for silicon device isolation
Inventor: ROBERTS MARTIN CEREDIG
IPC: H01L21/027
Filed: 1986-06-17
Abstract: A process is described which allows the forming of narrow oxide- filled trenches in single crystal silicon. This is achieved by using an oxide-etch resistant medium eg. poly-silicon, forming from this a remanent sidewall fillet (15), and using this fillet (15) as a mask to form a narrow rib (17) in underlying material. The substrate (1), but for that narrow region masked by the rib (17), is then covered with photoresist (19), and the rib (17) is removed to expose a narrow trench feature. The substrate (1) is then etched to define an isolation trench and this trench is filled with oxide to form the isolating structure. This process can be used to isolate both MOS and bipolar components. <IMAGE>

Title: Radio transceiver control device
Inventor: CORRIGAN NIGEL M
IPC: H04B1/40
Filed: 1986-11-22
Abstract: A control system for ensuring that a radio transceiver cannot be left in the transmit-mode either by a fault or through misoperation operates by monitoring R41, 44 the current taken by the transceiver and disabling the power supply 120 from at least the transmitter section if excessive current taken by the transceiver during transmit mode is detected for greater than a predetermined time period, this time period being set at well above the normal time period for continuous transmission. After a first time period (e.g. 15 secs) warning lamp 400 may be illuminated by relay 27, but if after a further period (e.g. 1 minute) excessive current is still being drawn, relay 112 operates to disable the power supply from the transmitter, and causes flasher 115 to make lamp 400 flash. <IMAGE>

IPC: G02F1/1347
Filed: 1987-10-09
Abstract: The display of an LCD device is selectively changeable to the forward or reverse type e.g. black on white or white on black, by modifying an LC device of a known type comprising transparent sheets 11, 12 having patterned electrodes 13, 14 of an oxide sandwiching a liquid crystal layer 10 and associated polarisers 15, 16 to further include an LC device, formed by an LC layer 23 and non-patterned electrodes 18, 19 of an oxide formed on sheet 12 and on another sheet 17, which is energised by a switching circuit 21, 22. Operation in the two types or modes is thus achievable in one instead of two separate display devices. The first LC device 10-14 introduces a 90 DEG  shift in the light polarised by element 15 and the second LC device introduces a further 90 DEG  or 0 DEG  shift depending upon whether switch 22 is open or closed. Operation in the two modes corresponding to day or night conditions may be controlled manually or by a light sensor. Applications may be in radios, vehicles, clocks, computers, toys, medical appliances etc. <IMAGE>

Title: Data transmission system
Inventor: BARLOW STEPHEN JOHN
IPC: H04Q11/04
Filed: 1987-11-24
Abstract: A data transmission equipment of the multiplexer type, e.g. as described in our Patent Specification No. 2 185 658 A, has a bus structure formed by parallel lines (10, 11) on a PCB backplate, with the circuit units (1, 2, 3, 4) on PCB's set at right angles to the bus structure. These units include a control unit (2) which also acts as an interface to one or more 2 Mb/sec. trunks, and a number of so-called tributary units (3, 4) which give access to subscriber and other user circuits. The principles of the above arrangement are extended by the provision of processors (5) in the tributary units so that processing is largely distributed. This has the merit of enabling the bus structure to be simplified. <IMAGE>
