Title: LPG Fuel Tank, and Fuel Supply System, for Engines
Inventor: MARCON ROBERT VICTOR
IPC: F02M21/02
Filed: 1996-04-25
Abstract: An improved fuel supply system (20), fuel tank (22 or 50), and fuel (30), whose use in small internal combustion engines provides greatly reduced emissions, longer engine life, reduced maintenance, higher reliability, and safety.   These fuel tanks (22 or 50) are partially filled with a LPG fuel (30) and are also connectable to the fuel supply system (20) by a corresponding fuelling receptor (32 or 56).  The fuel system (20)  is  itself  comprised,  in  combination,  of  a  fuelling receptor (32 or 56) which is then followed in series and in fuel flow communication by a fuel conduit (36), a fuel lock valve  (38), another fuel conduit  (40),  a primary pressure regulator (42), still another fuel conduit (44), and finally a fuel-air mixer (46).  The aforementioned design is the basic operation system to which may be added a secondary pressure relief valve (60), a fuel filter (64), a manual close-off valve (66),  a fuel vaporizer  (96),  a heat sink  (98),  and other components in order that the fuel system (20), and fuel tanks (22 or 50) may function under different operating standards, conditions or environments.

Title: Insulative support and short-circuit braces for medium voltage switchgear
Inventor: ROBIRDS TIMOTHY GORDON
IPC: E04C3/00
Filed: 1996-05-31
Abstract: A brace for resisting the repulsion forces generated between the bar bars in multiphase switchgear by short circuit currents has an electrically insulative cross-member bolted directly to the bus bars and a plurality of longitudinally spaced electrically insulative fins extending laterally from the cross-member between adjacent bus bars a distance sufficient that the over surface distance between the bus bars over the cross-member and surfaces of the fins is at least a predetermined prescribed value. In a support brace version, the cross-member is an angle or other structural shape which is extended at each end for attachment to a support within the switchgear and additional fins are placed between the attachments and the outer bus bars to provide similar over surface distance between the bus bars and the support. The fins can be molded integrally with the cross-member or fabricated from sheet material and secured to the cross-member by an adhesive effecting an air tight seal.

Abstract: L'invention concerne un système et un procédé pour nettoyer un filtre à particules. Le filtre est nettoyé par l'apport d'énergie pour brûler la matière particulaire collecté sur ce dernier. Le système peut comprendre un thermocouple pour surveiller la température du filtre en divers emplacements. Une unité de commande électronique est prévue pour déterminer le point présentant une température maximale et générer un signal de commande proportionné à la température maximale. L'unité de commande peut déterminer si le signal de commande dépasse un point de consigne prédéterminé et dans ce cas, réduit l'apport d'énergie. L'unité de commande détermine aussi si le signal de commande se situe dans une plage prédéterminée, également désignée comme une largeur de bande de valeurs acceptables inférieures à la valeur de consigne. Si le signal se situe dans la largeur de bande, l'unité de commande contrôle l'apport d'énergie et le fait varier afin de maintenir le signal de commande dans cette largeur de bande.

Title: Composition and methods to improve neural outcome
Inventor: GLUCKMAN PETER DAVID
IPC: A61K38/05
Filed: 1994-12-20
Abstract: The tripeptide glycine-proline-glutamine(GPE) may be administered before or usually after injury, to reduce damage to the central nervous system. GPE appears useful for neuronal rescue particularly but not exclusively within the hippocampus. Advantages of GPE include a) that it crosses the blood-brain barrier so is effective by injected peripheral administration; b) it is unlikely to challenge the immune system; c) it is cheap: and d) its therapeutic ratio is high. GPE may be also be infused into the CSF. It may be administered prior to parturition or elective brain or cardiac surgery. Transdermal routes may be useful for chronic neural disorders. The CNS of mammals (including foetal mammals) after trauma including hypoxic/ischaemic experimental insults showed reduced damage under GPE protection as measured by histological assesment of cell damage or death and regional shrinkage.

Abstract: Method and device for manufacturing biaxially oriented tubing from thermoplastic material. The method comprises forcing the tube over a mandrel (3) at an orientation temperature of the plastic material, which mandrel comprises an expansion part (5) which produces expansion in the circumferential direction of the tube. Downstream of the mandrel and axial pulling force is exerted on the tube, and the biaxially oriented tube is cooled down. At a distance downstream of the mandrel the tube is drawn through a calibration opening (12) bounded by calibration means, the calibration opening being such that it produces a reduction in the external dimensions of the tube. Accurate regulation of the external dimensions of the tube is provided by regulating the distance between the mandrel (3) and the calibration means (12), in particular depending on the external dimensions of the tube measured downstream of the calibration means.

Inventor: KIDA KOICHI
IPC: C07C51/44
Filed: 1996-10-30
Abstract: A method for preparing an alkylbenzoic acid is herein disclosed which comprises subjecting an alkylbenzene having at least two alkyl groups of 1 to 3 carbon atoms to a liquid phase oxidative reaction with a molecular oxygen-containing gas in the presence of a soluble heavy metal catalyst to convert one alkyl group into a carboxylic acid, thereby preparing the alkylbenzoic acid, and impurities contained in the alkylbenzene recovered from the reaction solution are removed therefrom by distillation, water washing, alkali washing, a treatment with an anion exchange resin or a treatment with a solid adsorbent, and the impurities-free fraction is reused as a raw material. Furthermore, the conversion of the desired product is regulated to 25% or less in the liquid phase oxidative reaction, whereby the reaction is carried out in a boiling heat removal state and reaction heat is removed as the heat of vaporization. Thus, there can be decreased a dicarboxylic acid secondarily produced during the manufacture of the alkyl-benzoic acid which is a monocarboxylic acid by subjecting the alkylbenzene to the liquid phase oxidation, whereby problems such as the trouble of equipment operation and the deterioration of product quality can be solved.

IPC: H04M3/42
Filed: 1995-05-26
Abstract: In a telephone network, e.g. a cellular radio system, after a transaction (e.g. a call) has ended, the connection is not fully released. If another connection is to be setup on ending of a current call, e.g. a voice message or call completion to be a subscriber arrangement, a flag (F) is set in the connection management system (CM). The status of the flag (F) is used to determine if the signal in connection towards a termination (B) should be kept or released immediately. Depending on the status of flag (F) different actions are taken in the network. The connection may be maintained for a predetermined interval. Data (F, F1, F2), concerning the status of the flags are transmitted from switching centre (MSC1) to another switching centre (MSC2) if control of the network termination is transferred. If control of the network termination (B) passes to a switching centre not capable of supporting the service to which the flag (F1) relates, the flag status is stored in a buffer register (HLR) associated with the user until such time as it is again connected to a switching centre capable of supporting the service.
