Title: Radiation-controlled electrical switches
Inventor: LOVELL MERVYN CHARLES
IPC: H01L45/00
Filed: 1983-08-25
Abstract: A radiation-controlled switch (6) includes an optically active material (12), which is preferably a 1000 ANGSTROM  thick VO2 layer on a substrate (10), the optically active material having electrically mutually isolated contacts (14, 16) formed thereon, and being associated with a radiation source (8), which may be a laser, directing electromagnetic radiation at the optically active material wherein on incidence of the radiation from the source, at least part of the optically active material undergoes a phase change from a non- metallic to a metallic phase and establishes electrical contact between at least two of the contacts. Other optically active materials used are NbO2, Fe3O4, NiS, FeS, V2O3, V8O15 or MoTe2. <IMAGE>
Patent GB-2131341-A (GB)
Title: Plastics components of or for bearings
Inventor: MEINING HANS
IPC: F16C35/073
Filed: 1983-10-21
Abstract: A material for the production of dynamically stressed precision parts for bearings is disclosed. In order to prevent shrinkage of the material during the processing in a mould, after cooling or curing, an expanding agent is added. When the basic material is a thermoplastics, preferably 0.2 to 2% of an expanding agent is added. In order to prevent a bearing, which is secured on a shaft (11) by means of an insert-moulded plastics sleeve (12,14), from becoming loose as a result of shrinkage of the sleeve material, an expanding agent is added to the moulding compound. Accordingly, the plastics sleeve is seated under preloading between the bearing and the shaft, in which case the inner wall thickness resulting from the shrinkage is compensated for. A preferred working material is 100 parts polyamide, 10 parts glass fibre and 0.8 parts expanding agent. <IMAGE>

Title: Fire door made of g.r.c. only
Inventor: CROSS SYDNEY HAROLD
IPC: E06B5/16
Filed: 1983-10-27
Abstract: A fire door (10), intended to meet the requirements for a ship's cabin door for example, is made entirely of glass-fibre reinforced cement (grc). The door (10) is hollow, and three constructional methods are described. in the first (Figure 1), a framework (13, 14, 15, 16) of grc is clad with plane grc facing sheets (12), which may be of a type having high density faces and a low density core. In a second form (Figure 2), the facing sheets (28) have integral edge ribs (27, 29) and are adhesively secured back-to-back, leaving an internal hollow. In a third form (Figure 3), generally diagonally positioned ribs (32) on the facing sheets cross at crossing points (33) where they are secured together. The internal compartments or baffles within the hollow door reduce convection in the event of a fire. <IMAGE>

Patent GB-2138283-A (GB)
Title: Conference table
Inventor: AINCY JEAN GILBERT
IPC: H04R1/40
Filed: 1984-02-20
Abstract: Directional, preferably differential, microphones (11) at the back of the V-shape table point to respective speaker positions disposed at the front of the table substantially in line with the microphones (11). The microphones serve as selective sound pick-ups for receiving each speaker's speech and also for determining which one of the various possible speakers is actually speaking. A grating (26), e.g. of metal and with a fabric covering (25), and having longitudinal and cross bars (28,27), is disposed a short distance in front of the microphones between the microphones and the speaker positions. The grating provides a useful degree of "blinkering" to make the microphones relatively less sensitive to off-axis speakers than they would be without the grating. <IMAGE>

The antibody is useful for the identification and/or classification of a fungus of the genus Candida and for treating candidiasis.
Patent GB-2143372-A (GB)
Title: Applying barrier metal to a semiconductor
Inventor: SHIER JOHN SHOUSE
IPC: H01L21/768
Filed: 1984-06-15
Abstract: A titanium-tungsten (T2-W) barrier layer (70) is provided between a signal line and an N-type silicon region in a NPN transistor device having an emitter contact window (62) exposed to N-type silicon, a collector contact window (60) exposed to N-type silicon and a further contact window (64) having a layer (35, Fig. 7) of silicon dioxide over P-type silicon, by depositing a layer (70) of an alloy of titanium-tungsten on the surface of the processed semiconductor wafer and etching the titanium-tungsten layer out of the further contact window (64). The silicon dioxide layer (35, Fig. 7) is then etched out of the further contact window to expose the P-type silicon. A metallisation layer of aluminium is then deposited on the semiconductor wafer and undesired portions are etched away using conductor interconnect photolithography to define signal lines (100, 102, 104). Those portions of the titanium-tungsten layer not covered by the signal lines are etched away so that the titanium-tungsten layer provides barrier metal between the signal lines and the N-type silicon of the emitter and collector contact windows so that the signal lines connect directly to the further contact window. Alternatively the titanium-tungsten layer remains only in the emitter contact window. <IMAGE>

Patent GB-2167556-A (GB)
Title: Steam leak detection
Inventor: TERO BRIAN ALBERT
IPC: G01M3/24
Filed: 1984-11-20
Abstract: Steam leaks in a steam raising boiler are detected by microphones 13a-13f connected to the combustion space of the boiler via long narrow listening tubes 10a-10f. The signal from each microphone is amplified and filtered (14e-14f, 15 and 16) so that there is selectively passed a signal of frequency 4-8 KHz. The resultant signal is supplied to a display 17 with bar charts 18 whose range and bias is set so that (a) at a signal level of less than 74 dB corresponding to normal background noise no signal shows on the display, (b) a signal level of 74-94 dB operates to a first portion of the display range to indicate an abnormality, (c) a signal level of 94-114 dB operates a second portion of the display to indicate the presence of a steam leak and (d) a signal beyond 114 dB exceeds the range of the display and indicates that serious secondary damage is occurring. A colour change indicates the change from (b) to (c). <IMAGE>

Title: Credit and charge card processing systems
Inventor: JARMAN JOHN MICHAEL
IPC: G06Q20/00
Filed: 1984-12-10
Abstract: In order to effect a transaction using a credit or charge card, the processing system establishes two- way communication via a network (14) between a retailer unit (12a) and a computer (20) and also between authorization data bases (16) at the credit or charge card companies and the computer (20).

Title: Telephone subset apparatus
Inventor: GOODE PETER ANTON
IPC: H04M3/58
Filed: 1985-01-30
Abstract: A telephone subset circuit arrangement which renders the recall facility of a subset compatible with PABX's whose recall systems are either earth recall or Timed Loop Break recall, without the need for any modification to the subset prior to installation. In its simplest form, the circuit includes a changeover switch operable by a pushbutton (K1) and effective to close contacts 1 and 2 and open contacts 2 and 3. This removes a short circuit from a Timed Loop Break system (TLB) and causes an auxiliary relay to drop out and thereby prepare the exchange equipment for further dialling signals. <IMAGE>
