Title: Decantation tank sludge scraper - retracted for reverse stroke by mech cam action actuated by scraper traction force
IPC: B01D21/18
Filed: 1972-11-28
Abstract: The scraper is operative in one direction across the tank and retracted to return without scraping. As the scraper carriage comes to each end of its travel, a bell crank lever is pivoted by cam action of the underside of the carriage track and a roller on one end of the lever, the other end of which carries the scraper blade; the resets the blade for its next stroke. The reset action repeats wuite automatically so long as the carriage traverses back and forth, so no motor is required on the carriage which can be pulled by a remote traction motor in protected conditions.

Inventor: EADON-CLARKE CHRISTOPHER ERSKI
IPC: B29C65/74
Filed: 1947-04-12
Granted: 1949-04-25
Abstract: 623,736. Seaming rubber: moulding hollow plastic articles. STANDARD TELEPHONES & CABLES, Ltd., CLARKE, C. E. EADON-, and MICKLEWRIGHT, P. L. April 13, 1946, No. 11397. [Classes 70 and 87 (ii)] [Also in Groups VIII and XI] Hollow articles such as bulbs made from a plurality of sheets of thermo-plastic material such as rubber or polyvinyl chloride are edge-seamed by placing the sheets between electrodes one at least of which has a dividing and seaming edge, applying a high frequency alternating or pulsating electric potential for a sufficient period to soften the thermo-plastic material, removing or substantially reducing the potential and subsequently applying a mechanical pressure sufficient to form a seam. In a device for seaming rubber bulbs, 8 bottom electrodes 16 (Fig. 14) fixed to back plate 31 are covered with a sheet of unvulcanized rubber, two plugs per mould are then placed in position by means of dimpled template 33 and then another sheet of rubber and top electrode 32 placed in position. The current is switched on and after the rubber has softened the power is cut off and the electrodes brought together by pressure, firstly to consolidate the welded joint and then to cut away excess material. The electrodes are preferably chamfered on the inside. Additional electrode limbs may be provided to form pockets in articles such as air cushions. The frequency used is normally above 5 megacycles. The Provisional Specification describes also a similar process in which the heating is produced by any suitable means.
Patent GB-2361265-A (GB)
Title: I.c. engine with steam power stroke
Inventor: HARKER MATTHEW
IPC: F02G5/02
Filed: 2000-04-13
Abstract: A four-stroke reciprocating-piston i.c. engine includes a steam generator 5 in which water is converted to steam by the heat of the exhaust gases discharged from the cylinder 1. The steam is introduced via a steam valve 6 into the cylinder in the stroke normally used for induction to provide an additional power stroke. A substantial part of the energy which would have been lost to the atmosphere as heat in a conventional i.c. engine is thus recovered. Steam exiting the cylinder passes through a condenser 7 from which the water is pumped to a header tank 10 linked to the water jacket 3. The condensation of the steam reduces the pressure in the cylinder to below atmospheric pressure, drawing the fuel/air mixture into the cylinder without needing movement of the piston. On starting, the engine operates on a conventional four-stroke cycle with the inlet valve opening at the start of the induction stroke; when the engine has reached its working temperature the timing of the inlet valve is changed so that it opens at the end of the steam stroke.

Title: Particle detector using a second radiation emitter which becomes operative only if the signal from a first emitter signal exceeds a predetermined value
Inventor: BELL KENNETH FRAZER
IPC: G01N21/53
Filed: 2001-09-25
Abstract: Detector has both blue and infra-red radiation emitters (3 and 3A). Light is forward scattered by the particles in scatter volume (9). The emitters are pulsed at different intermittent frequencies enabling the control means (16) to produce separate signals (21, 23) corresponding to the scattered blue and infra-red lights. A comparator (25) takes the ratio of these two signals to produce a smoke-dependent warning output to the alarm (32). Smoke particles scatter more blue light than infra red. The apparatus normally operates in monitoring mode in which the infra-red emitter (3A) is pulsed intensively but at a low flashing rate. The second emitter (blue light) is maintained <I>inoperative</I>, until the first emitter (infra-red) radiation scattering causes the photodiode (15) exceeds a predetermined output, at which point the blue (second) emitter is rendered <I>operative</I>. The state of second emitter may be changed between operative and inoperative in various ways e.g. by energising/de-energising the second emitter or by increasing/decreasing its amplitude or its intermittent frequency. Alternatively, the control system may keep the second emitter inoperative until the signal form the first emitter exceeded a predetermined value and this has elapsed a specific length of time.

Title: Method and apparatus for fault detection in a radio transceiver
Inventor: TURNER NEIL WILLIAM ASHLEY
IPC: H04B17/00
Filed: 2002-06-24
Abstract: The invention relates to a system for fault detection for a radio transceiver 200. The apparatus comprises a circulator 211 connected between a transmitter power amplifier (209) and a transceiver output 213. A load port 219 of the circulator 211 is the output for a reflected signal from an antenna subsystem 213, 221, 223, 225 and is coupled to a receiver unit 231. The receiver unit 231 measures a load port parameter, preferably the power level, of the reflected signal on the load port 219. The fault detection system determines if a fault condition exists in response to the measured load port parameter. Specifically, a fault is determined to exist if the reflected power level is above a given threshold. The system is applicable to for example base stations for a cellular communication system.
