Patent GB-2086156-A (GB)
Title: Low power consumption electronic circuit
IPC: G04C10/00
Filed: 1981-09-29
Abstract: According to the present invention, the voltage of a battery is supplied to an electronic circuit such as a watch circuit through a step down circuit which is constructed of capacitors and switching MIDFETs. The step down circuit performs a current converting operation as well as a voltage converting operation. The operating current of the electronic circuit is reduced by the reduction in the operating voltage of the same. As a result that the operating current level of the electronic circuit is dropped and that the current conversion is performed by the step down circuit, the battery current is relatively largely dropped. The construction thus far described elongates the lifetime of the battery. According to the present invention, therefore, there is provided a circuit which is proper for driving the step down circuit.

Title: Sensing Condition of Loading of Conveyors on Vehicles
IPC: G01F3/00
Filed: 1981-12-01
Abstract: Sensing means connected to the shaft of an elevator 1 senses the condition of loading of the vanes and of a conveyor in the shaft and feeds the signals to a computer for evaluation.

Title: Electrophotographic copier
Inventor: ISHIDA MASATO
IPC: G03G15/043
Filed: 1981-12-16
Abstract: A copier with an image density selector, has means for setting a standard density when the copier is first switched on. The standard density may also be set if a predetermined time elapses without a copy being made. As shown, density select switches SW1-5 energise relays K1-5 (and LED indicators 71-75) which switch resistors into a phase control circuit (Fig. 14A not shown) of the copier light source. When the copier is first switched on, the logic 127-134 energises relay K3 to set a standard, intermediate copy density. Thereafter a different density may be selected by the switches SW1-5. During copying, a signal on line 62 prevents re-setting of the density. When the required number of copies has been made, a signal on line 61 starts a timer 123 which sets the standard density if no further copy is made within a predetermined time. Further details are claimed in the parent Application 7922040 (GB 2024438A) and co-divisional 8137971 <IMAGE>

Title: Effluent discharge tube
Inventor: OLDHAM ANTHONY GORDON
IPC: E03F1/00
Filed: 1982-05-07
Abstract: The invention is concerned with effluent discharge tubes or risers (12) each having a flange (14) at one end by which it can be attached to flanged outlets (18) on a main effluent discharge pipe (10) designed to extend out to sea. In order to prevent the tubes or risers from being damaged by fishing nets or other tackle used by trawlers or fishermen, each tube is made of a nitrile rubber or equivalent material with a fabric reinforcement so that it can yield or flex when fishing nets or other tackle which have become hooked on them are pulled away. Alternatively, each tube or riser can be provided with flexible bellows (30) at its flanged end, the bellows being provided with a flange for attachment to the flanged outlet (18) on the main effluent discharge pipe (10). <IMAGE>

Title: Handle assembly for a pressurised dispensing container
Inventor: REED NORMAN LEONARD
IPC: B65D83/14
Filed: 1982-08-10
Abstract: A handle assembly for a pressurised dispensing container consists of a handle 12 and a collar 11. The collar is fitted with legs 28, provided with bulbous portions 29 which clip resiliently into a groove 20 in the valve cup. The handle is provided with lugs 41 which engage with the collar, the handle being inserted into the collar and twisted to engage the lugs 41 with the collar to retain the handle. The lugs also press against legs 28 to prevent the collar becoming detached from the cam 13. A ratchet surface 30 is provided around the top of the collar which is engaged by a tab on the handle as the handle is twisted to lock it into the collar. The rachet surface thus prevents the handle from being disengaged by being twisted in a direction opposite to that required for engaging the lugs. <IMAGE>

Title: Heating device
Inventor: TAYLOR WILLIAM FOTHERGILL
IPC: B63C11/28
Filed: 1982-08-18
Abstract: A heating device, comprising electrical heating elements (24) disposed in a diver's suit (21), incorporates separate sources of electrical supply for the heating elements (24) on opposite sides of the diver's body (20). The electrical supply may be batteries (25, 26) or may be secondary windings (28, 29) of a transformer (30). In the former case the batteries may be mounted on the diver (20) at the same side as the element or elements (24) to which each is connected, or in either case the electrical source (25, 26, 28, 29) may be remote from the diver (10). The provision of independent power supplies to the opposite sides of the diver (10) precludes electric shock from passing across the diver's body in the event of insulation failure. <IMAGE>

Title: Improvements in coal extraction
Inventor: CLARKE JAMES WILLIAM
IPC: C10G1/04
Filed: 1983-01-14
Abstract: Coal is extracted using a mixed solvent which includes a substantially aromatic polycyclic component boiling above 270 DEG C and at least 25% by weight of a substantially naphthenic polycyclic component, at a temperature of 400 to 500 DEG C. Although neither component is an especially good solvent for coal by itself, the use of mixed solvent gives great flexibility to the process and offers efficiency gains. The aromatic component can be a 270-360 DEG C fraction distilled from the coal extraction product and the naphthenic component can be a 180-300 DEG C fraction obtained by catalytic hydrogenation/hydrocracking of a portion of the coal extraction product. <IMAGE>

Patent GB-2185206-A (GB)
Title: Hand tools
Inventor: RETFORD WILLIAM
IPC: B23K31/10
Filed: 1986-01-15
Abstract: A hand tool such as a fork is produced by first forming a blank 10 using a profile cutting technique, particularly a burning technique eg. oxy-fuel, plasma or laser. This produces a dramatic reduction in scrap. Preferably a plurality of blanks are cut out, and components of the tools, e.g. fork tines 15, are interdigitated to further reduce scrap. A still greater reduction in scrap can be achieved by cutting out the tines in an initial position in which they lie closer together than they will in the finished product. They can subsequently be deformed into their final position during a finishing operation. <IMAGE>

Title: Sealing assemblies

When the assembly is axially compressed (Fig. 3), the deformable washers fill the troughs and any excess material is cut off as the knife edges (110) contact the members thereby presenting a continuous metal surface to the exterior. The material of the washer (106) may be copper fibre or P.T.F.E. The metal ring is preferably made of the same metal as members 101 and 102. <IMAGE>
Patent GB-2210227-A (GB)
Title: Radar systems
Inventor: SINNOCK PETER J
IPC: G01S7/40
Filed: 1986-02-01
Abstract: A CW radar system is capable of operating in ranging and non-ranging modes. In non-ranging mode an unmodulated signal identifies a target, whereupon the ranging mode starts and the transmitted radiation is frequency modulated so that the frequency of the output varies linearly in time. This causes a frequency shift to be detected between the received radiation reflected from a target and the radiation being transmitted at the time of reception. A proportion of this frequency shift will be due to the Doppler effect and the remainder will be due to the modulation. That component of the frequency shift due to the modulation is proportional to the time taken for the return journey from the radar to the target and can be used to derive the range of the target. The frequency of the signal transmitted by a slotted array antenna 2 is modulated by range modulator 10 which controls an oscillator 4 having a PROM store of frequency control data. Received signals from slotted array antenna 20A-D are mixed 24 and filtered 30 and then processed at 32 to give frequency difference data and hence target identification data. <IMAGE>
