Patent CA-2043794-A1 (CA)
Title: Easy grip bottle
Inventor: ZOGG JON
IPC: B65D1/00
Filed: 1991-06-03
Abstract: The bottle has two essentially identical indentations on essentially opposite sides for gripping and manipulating the bottle. The indentation are designed to provide for the same gripping feel whether gripped front or the back. The indentations are also designed to accept a thumb and one to four fingers. The positive gripping with the same grip feel allows the bottle to be used in either hand. This decreases the number of times that a bottle must be handled during use. It also decreases the likelihood that the bottle will be dropped while being handled.

Patent CA-2048569-A1 (CA)
Inventor: D'ANDRADE BRUCE M
IPC: A63H33/30
Filed: 1991-08-07
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention is directed toward a toy water gun which is operated by selectively releasing water from a water reservoir pressurized with air.  The present invention has a manually operated pump incorporated into the design.  As the pump is cycled, water and air is drawn from a water storage tank.  Once drawn, the water and air are forced into a pressure reservoir.  As the amount of water and air forced into the pressure reservoir increases, the pressure on the water within the pressure reservoir increases.  The pressure of the water and air within the pressure reservoir increases with each cycle of the pump, until the pump can no longer overcome the pressure of the water and air within the pressure tank.          The pressurized water and air within the pressure tank has an avenue of release that is regulated by the trigger mechanism of the invention.  When no force is applied to the trigger, the pressurized water and air are held at bay with no means of release.  When force is applied to the trigger, the water is first released from the pressurized container and is channeled through a narrow nozzle.  The escape of the water, under pressure, through the narrow nozzle creates a stream of propelled water that lasts as long as the trigger is engaged or until the air pressure propelling the water equals the ambient pressure.

Patent CA-2065736-A1 (CA)
Inventor: ECONOMY RICHARD
Filed: 1992-04-09
Abstract: In a computer image generation system, the number of vertices which define each of a plurality of terrain-defining polygons is augmented in real time for providing finer detail and for effecting substantially continuous smooth level of detail (LOD) transition. Augmented vertices may have components that are statistically derived, in which case it is not necessary to store and/or predefine them. Alternatively, some vertex components may have predetermined values derived from mapping data or from other deterministic sources and may be stored in compact form. Processing polygons, typically triangles defined by selected ones of the sum of the augmented vertices and the original vertices, may be used for displaying the finer detail. Statistically derived finer detail is especially suited for providing non-specific detail to features such as terrain, while deterministic data allows highly accurate representations of specific 'real world' locations. The decision to augment vertices is controlled by a predetermined breakup criteria, which may be selected as one, or a combination, of: range from the viewpoint; angle from the viewpoint boresight; desired maximum error; and other defined criteria.

IPC: G01N30/12
Filed: 1991-09-27
Abstract: On décrit un appareil (10) et des méthodes de chromatographie en phase gazeuse qui permettent de réaliser des analyses par chromatographie en phase gazeuse plus rapidement que les techniques antérieures et qui préviennent également le masquage des pics chromatographiques correspondant à des substances d'intérêt, par superposition de ces pics à des pics intenses et de longue durée correspondant à d'autres constituants d'un mélange organique.  L'inversion de la direction du courant dans la colonne (32) au moment de l'élution ou juste après l'élution d'un pic de haute intensité et de longue durée correspondant à certains constituants du mélange, ce qui entraîne le retour dans la chambre de focalisation thermique (14) des constituants qui restent et leur réinjection ultérieure, constitue un aspect principal de l'invention.  On peut, en arrêtant le processus à ce point, réduire la concentration des matières donnant un pic intense et de longue durée qui ont éluées, ce qui permet, après réinjection ultérieure, de déceler dans le chromatogramme des caractéristiques d'intérêt qui, autrement, auraient été masquées.

Title: Method for the analysis of a gas sample, analysis arrangement, uses thereof and test plant comprising the said arrangement
Inventor: MATTER ULRICH
IPC: G01N33/44
Filed: 1991-12-04
Abstract: ABSTRACT     Rapid sequences of gas samples (G) are taken to a semi-conductor sensor (60a,b,c) for analysis.  The analysis procedure is accelerated by differentiating the semiconductor sensor output signals in time (61) and taking successive gas samples (59) to the semiconductor sensors (60a to 60c) sequentially.  In cycle stages in which the semiconductor sensor concerned (60a to 60c) receives no gas samples, the lines and casing are flushed with gas (S).  The effect of the flushing process on the semiconductor output signal (A) is minimised by adjusting the flushing gas and/or the flow rate ratio between the flushing gas and the gas sample in the semiconductor region.
