Patent ZA-849202-B (ZA)
Title: Optical amplifier
Inventor: BYRON KEVIN CHRISTOPHER
IPC: H01S3/094
Filed: 1984-11-26
Abstract: @ Use is made of stimulated Raman emission to induce gain in an optical signal (13) of a first wavelength. The optical signal (13) and a pump signal (14) are synchronously coupled to a length of optical fibre (15). The pump signal is at a second wavelength. The first wavelength corresponds to one Stokes shift from the pump signal. The pump signal is generated by a semiconductor laser (11) and thus only relatively low pump powers are involved in comparison with the conventional use of YAG lasers as the pumps, however significant gain is achieved despite the low pump powers. Preferably the optical fibre (15) has a high Raman cross-section and a low transmission loss, for example GeO<sub>2</sub> doped SiO<sub>2</sub> or pure Ge0<sub>2</sub>.

Abstract: 1. A process of producing aluminum fluoride from aluminum hydroxide or alumina hydrate and hydrogen fluoride in a circulating fluidized bed system including a fluidized bed reactor, a cyclone separator and a recycling line, characterized in that partly reacted aluminum hydroxide circulated in a cooling cycle is added to fresh aluminum hydroxide or alumina hydrate in a first stage, in which the aluminum hydroxide is contacted with the hydrogen fluoride-containing exhaust gases from the circulating fluidized bed system so as to form a gas-solids suspension at a temperature of 150 to 250 degrees C, whereafter the solids are collected from the gas stream, at least part of the collected solids are passed through a cooler, cooled solids are re-contacted with fresh aluminum hydroxide or alumina hydrate, and a partial stream of the collected solids is supplied to the circulating fluidized bed system and is reacted therein at a temperature of at least 450 degrees C with hydrogen fluoride supplied in the form of a gas in a concentration up to 25 vol. %.

Title: Polymer powders
Inventor: FARRAR DAVID
IPC: C09K23/52
Filed: 1985-06-28
Abstract: A water soluble or swellable polymer gel is dispersed into a liquid phase to form a fluid composition and is worked whilst in that composition. The liquid phase is an aqueous slution of an equilibrating agent that substantially prevents aggregation of the particles or dissolution of the polymer during the working. The working may be, for instance, milling, extraction of impurities, extraction of water, transportation or chemical modification. Preferred equilibrating agents are sodium polyacrylate and polydiallyl dimethyl ammonium chloride.

Title: Overload relay having adaptive differential mechanism
Inventor: FAJNER MICHAEL JACOB
IPC: H01H71/14
Filed: 1988-12-15
Abstract: In a plural phase overload relay, a pivot lever (12) is mounted to the ambient compensator deflector (9), and a second pivot lever (34) is mounted to both driver and follower slide bars (36 and 38) and driven thereby to engage and pivot the first lever on the ambient compensator deflector to trip a cut-out switch. The ambient compensator deflector adjusts both the three phase current trip threshold and the loss of phase current trip threshold, and also affords ambient compensator of each. A constant ratio relationship between these two thresholds is provided throughout the entire range of current trip threshold settings. The driver bar moves a first distance for three phase trip and a second shorter distance for loss of phase trip. The ratio of these distances is constant notwithstanding adjustment by the ambient compensator deflector changing the length of such distances.

Title: Power tool
Inventor: CAMPLING BARRY
IPC: E02D7/06
Filed: 2001-05-12
Granted: 2004-10-13
Abstract: A power tool ( 1 ) has a percussive driving implement for driving an impact tool ( 8 ). The driving implement, which may be hydraulic or pneumatic, retracts the impact tool ( 8 ) on its return stroke, against the force developed by heavy-duty elastic ropes ( 24 ). During the impact stroke the impact tool ( 8 ) is urged downwardly by the elastic ropes and, if the tool is upright, by gravity. At the start of the impact stroke the ram ( 10 ) is uncoupled by a ball clutch. At the beginning of the return stroke the ball clutch acts to couple the ram once again to the weight ( 20 ) and impact tool ( 8 ), in order to lift these to the retracted position. The uncoupling of the ram for the impact stroke reduces the loss arising from the resistance of the ram.

Title: Catalyst heat retention system for multi-fuel engine
Inventor: BARBARIE T VINCE
IPC: B01D53/94
Filed: 2003-01-06
Granted: 2006-07-05
Abstract: A method and system are provided for reducing tailpipe emissions of a lean burn, multi-fuel engine (20) by improving the efficiency of an oxidation catalyst (50) of the engine through avoiding unnecessary cooling of the catalyst. For instance, a lean burn, unthrottled dual fuel engine (20) may be configured to route exhaust gases away from a methane reducing catalyst (50) of the engine during periods of diesel-only operation. Those gases that could otherwise lead to undesired cooling of the methane reducing catalyst. The catalyst thus remains hotter and maintains higher conversion efficiencies than it would if gases were always exhausted through the methane reducing catalyst.
Patent GB-2384953-B (GB)
Title: Mobile-assisted network based techniques for improving accuracy of wireless location system
Inventor: STILP LOUIS A
IPC: H04W4/90
Filed: 2001-06-26
Granted: 2004-07-14
Abstract: The accuracy of the location estimate of a Wireless Location System is dependent, in part, upon both the transmitted power of the wireless transmitter and the length in time of the transmission from the wireless transmitter. In general, higher power transmissions and transmissions of greater transmission length can be located with better accuracy by the Wireless Location System than lower power and shorter transmissions. Wireless communications systems generally limit the transmit power and transmission length of wireless transmitters in order to minimize interference within the communications system and to maximize the potential capacity of the system. Several methods meet the conflicting needs of both systems by enabling the wireless communications system to minimize transmit power and length while enabling improved location accuracy for certain types of calls, such as wireless 9-1-1 (emergency) calls. Such methods include mobile-assisted techniques in which the mobile unit includes functionality to assist in improving location accuracy. The WLS locates the transmitter (mobile unit) while the latter is using a modified transmission sequence comprising a message sent from the wireless transmitter using transmission parameters different from the normal transmission parameters broadcast on the forward control channel by the base stations in the associated wireless communications system. A trigger event, such as the user dialing 9-1-1, causes the mobile unit to operate in the mode in which the modified transmission sequence is used.

Title: Application of zippers to film material
Inventor: LEIGHTON MURRAY EDWARD BRUCE
IPC: B31B19/90
Filed: 2003-05-20
Granted: 2006-01-25
Abstract: The apparatus applies a transverse zipper strip to a film ( 10 ) moving continuously in a direction ( 12 ). A continuous belt ( 18 ) is driven by sprocket wheels ( 16 a , 16 b) and carries upper seal bars ( 22 a , 22 b , 22 c) which receive pre-cut lengths of zipper at station ( 3 ). The pre-cut lengths are attached to the film ( 10 ) by a lower seal bar ( 24 ) which moves towards the film ( 12 ) at position A when an upper seal bar carrying a zipper strip is located directly above the film. Sealing takes place as the upper and lower seal bars move at the same speed as the film ( 12 ) from position A to position B where the zipper is released from the upper seal bar ( 22 c). The process then repeats for the next zipper strip length.
