Filed: 1996-12-19
Abstract: The present invention provides a monoclonal anti-idiotype antibody 11D10 that elicits an immune response against a specific epitope of a high molecular weight mucin of human milk fat globule (HMFG) and a hybridoma that produces 11D10. The hybridoma that produces 11D10 was selected by specific procedures. 11D10 induces an immunological response to HMFG in mice, rabbits, monkeys and patients with advanced HMFG-associated tumors. This invention provides compositions derived from polynucleotide sequences encoding the variable light and/or variable heavy regions of monoclonal anti-idiotype antibody I1D10, as well as polypeptides encoded thereby. The invention also provides compositions which can be used in the detection or treatment of HMFG-associated tumors.

Abstract: A grass trimmer having a support shaft with reciprocating cutters at the bottom and a support wheel on the support shaft adjacent the cutters for supporting the cutters just above the ground. A hand grip on the upper end of the support shaft is used to "walk" the trimmer along the grass, rolling along on the support wheel, while the cutters are relatively reciprocated to cut grass.    The cutters can be relatively reciprocated by operating a hand lever on the shaft, which, through a first drive means, reciprocates one of the cutters relative to the other. The cutters can also be reciprocated by the rotation of the support wheel through a second drive means. Preferably the second drive means can be used together with the first drive means. The trimmer preferably has energy storage means associated with the drive means for more evenly operating the cutters.

Abstract: Mixed oxides of cerium and zirconium as well as solid solutions and cerium oxides are produced having improved thermal stability. The process involves the formation of cerium and zirconium oxides, mixed oxides and solid solutions by methods such as co-thermohydrolysis and co-precipitation, followed by washing or impregnating with an alkoxylated compound having greater than (2) carbon atoms. After the washing or impregnating step, the mixture is calcined to form oxides having very high surface area and oxygen storage capacity. The improved thermal stability of the oxides makes them advantageous for use in applications such as catalytic converters.

Title: Method for chemical vapour infiltration of refractory substances, especially carbon and silicon carbide
Inventor: BENZINGER WALTHER
IPC: C04B41/81
Filed: 1997-11-07
Abstract: Disclosed is a method for chemical vapour infiltration (CVI) of refractory substances, especially an isothermic, isobaric method of CVI, especially of carbon (C) and silicon carbide (SiC), based on diffusion in a porous structure, whereby the pressure of the gas or partial pressure of an educt gas contained in the gas and the dwell time of the gas in the reaction zone are set at a given temperature in the reaction zone so that a separation reaction occurs in the porous structure in the area of pressure or partial pressure of the saturation adsorption of the gaseous and volatile compounds forming the solid phase. Saturation adsorption means that the separation speed remains substantially constant at an increased pressure of the gas or the partial pressure of the educt gas and the reaction of the educt gas is limited in such a way that no more than 50 % of the elements supplied in the educt gas forming the solid phase as it flows through the reaction zone are separated as a solid phase in the porous structure. The flow through the porous structure occurs in a straight line from bottom to top via slits substantially similar in width, ranging from 1-50 mm.

Abstract: Method and apparatus for enhanced recovery of subterranean deposits. A heating fluid (32) circulates in a concentric tubing assembly (19) which attaches to a downhole heat exchanger (25).      A convertible fluid (35) descends to the downhole heat exchanger (25) in the concentric tubing assembly (19) where it converts to vapor (30) by transfer of heat from the heating fluid (32). The vapor can then be used to liquefy viscous subterranean deposits (10). A feed control valve (30) controls the rate at which convertible fluid enters the downhole heat exchanger (25). Scale produced by the vaporization of the convertible fluid is purged by a purging valve (85) into the well sump.

Patent CA-2273950-A1 (CA)
Title: System and method for the detection of vehicle rollover conditions
Inventor: DUNWOODY ANDREW B
IPC: B60K28/14
Filed: 1997-12-08
Abstract: A system uses multiple tilt sensors mounted to the vehicle frame and the vehicle suspension system to detect lateral acceleration and lateral load transfer. The system uses these measurements to determine a lateral load transfer ratio indicative of an actual roll moment compared to a maximum roll moment. The measurements from the tilt sensors are also used to calculate an effective center of gravity height. A display coupled to the system provides the vehicle operator with a read out of the load transfer ratio and effective center of gravity height. The display enables the vehicle operator to more completely understand the nature of the vehicle load and thereby allow the vehicle operator to avoid conditions likely to lead to a vehicle rollover accident.

IPC: F02C7/052
Filed: 1999-07-19
Abstract: According to the present invention, the shape of a passage in an intake-air duct communicated with the suction side of the intake-air filter is regulated so that snow is heaped up in the intake-air duct, and accordingly, the volume of snow reaching the intake-air filter is reduce in order to prevent the intake-air filter from clogging, and to prevent the flow rate of intake-air into a gas turbine from being lowered. In order to attain the above-mentioned purpose, there is provided, according to the present invention, an air-intake method for a gas turbine, in which intake-air 18 taken from a fresh air intake port is fed downward through a second intake-air duct in a substantially vertical direction, and then is fed in a substantially horizontal direction. Thereafter, dust is removed from the intake-air within an intake-air filter chamber, and then, is led into the gas turbine.

Abstract: L'invention porte sur un procédé et un appareil de compensation d'effets à variation temporelle telles que la température dans une cellule à cristaux liquides, notamment une cellule à cristaux liquides en biseau (10). On prend la température des cristaux liquides (10) soit directement à l'aide d'un thermocouple ou analogue, ou par un dispositif optique (82, 86) dépendant de la température des cristaux liquides. Par exemple, un détecteur d'intensité (86) contrôle la rotation de polarisation d'un faisceau sonde (84) de lumière ayant une longueur d'onde sensiblement différente de celle du faisceau (28) modulé par les cristaux liquides, et un circuit de rétroaction (90) maintient l'intensité à une valeur prédéterminée correspondant à la longueur optimale de la trajectoire du faisceau modulé (28) dans les cristaux liquides. Le signal de réaction issu de la mesure de la température est utilisée pour modifier efficacement l'intervalle rempli de cristaux liquides. Pour une cellule en biseau, la taille de l'intervalle est modifiée par le déplacement de la cellule dans le sens biseautage. Il existe d'autres structures cellulaires dans lesquelles la taille de l'intervalle est modifiée physiquement par le déplacement mécanique des parois de la cellule.
