Title: Tertiaryaminoalkyllithium initiators and the preparation thereof
Inventor: KERNS MICHAEL L
IPC: C08F36/04
Filed: 1997-12-10
Abstract: Relatively pure tertiaryaminoalkyllithium initiators suitable for anionic polymerization reactions are prepared at low temperatures in an organic ether by reacting an equivalent excess of lithium metal with a tertiaryaminoalkylhalide.

Abstract: On simule le mouvement de particules, telles que de la neige, dans une image, produite par ordinateur, qui représente depuis un point d'observation donné, un espace naturel simulé tridimensionnel où se déplacent ces particules. On définit un modèle tridimensionnel constitué d'un arrangement régulier de cubes accolés de dimensions déterminées. On définit un objet dont les dimensions correspondent à celles des cubes et dont les caractéristiques sont telles qu'il représente le mouvement des particules dans l'espace qu'il occupe. Le modèle tridimensionnel constitué de cet arrangement de cubes est, d'un point de vue théorique, positionné dans l'espace naturel simulé de façon que le point d'observation se trouve dans une de ses régions pour que le champ de vision concernant les particules, vu du point d'observation, se trouve toujours dans ledit modèle. Comme le point d'observation évolue dans l'espace naturel simulé, il est traduit en pas dont l'ordre de grandeur correspond à l'arête d'un cube. Le modèle est déplacé dans l'espace naturel simulé, ce qui permet de maintenir le point d'observation dans sa région choisie. L'image produite englobe le modèle où l'objet, qui représente les particules mobiles, occupe chacun des cubes. La visibilité des cubes s'atténue avec leur éloignement du point d'observation pour cacher les limites du modèle. Par rapport au point d'observation, ce dernier est placé de façon qu'un point théorique, placé sur une ligne traversant ce point d'observation dans une direction déterminée par rapport au déplacement de ce point d'observation, se trouve toujours dans une région centrale déterminée du modèle. La distance séparant ce point théorique et le point d'observation est fonction de la vitesse de déplacement de ce dernier.

Title: Movable grip for double-ended wrench
Inventor: MACOR RICHARD J
IPC: B25B13/08
Filed: 1998-06-29
Abstract: A double-ended wrench is described with a movable gripping means to improve user comfort, torque and continuous-use capabilities. The double-ended wrench has two wrench heads positioned, one at each end of an elongated handle.

Patent CA-2243304-A1 (CA)
Inventor: FRUGOLI D CRISTINA
IPC: A01K1/015
Filed: 1998-07-16
Abstract: An improved, fast-clumping animal litter which substantially immediately upon wetting with aqueous liquid forms a clump of durable clump strength for removal from the unwetted litter substantially immediately or within hours.  The inventive animal litter includes particulate non-swelling clay, swelling clay and starch.  A preferred animal litter utilizes pregelatinized corn starch at relatively low amount which surprisingly permits decreasing the amount of swelling clay below the minimum amount conventionally required for autogenous clumping clay litters.

Title: Assembly for sensing and/or monitoring a predetermined level in a vessel
Inventor: GETMAN IGOR
IPC: G01F23/296
Filed: 1998-09-21
Abstract: An assembly for sensing and/or monitoring the level of a material in a vessel includes a level sensor mounted in the vessel so that it comes into contact with the material when the material has attained a predetermined level.  The  level  sensor  contains  a  low-frequency sensing system and a high-frequency sensing system. The low-frequency sensing system is formed by a mechanical vibrator  system  induced  to  vibrate  at  its  natural resonant  frequency,  and  establishing  whether  the mechanical  vibrator  system  is  in  contact with  the material or not is achieved by evaluating the frequency and/or  amplitude  of  the  mechanical  vibrations.  For forming  the  high-frequency  sensing  system high-frequency elastic vibration is induced in a component of  the  level  sensor,  and  establishing whether  this component is in contact with the material or not is achieved by evaluating an electric signal generated as a function of the high-frequency elastic vibration.
Patent CA-2249941-A1 (CA)
Inventor: MAGUIRE DENNIS
IPC: B65G15/16
Filed: 1998-10-09
Abstract: A device for controlling the conveyance of particulate material on a conveyor belt comprises a frame with an endless belt attached thereto. The apparatus is positioned above the conveyor belt and in frictional contact therewith whereby the motion of the conveyor results in motion of the endless belt on the apparatus. The particulate material thereby is passes between the endless belt and the conveyor belt and any bouncing movement of such material is prevented. Use of the present invention on conventional conveyor belts controls the dispersion of the particulate material carried thereon and allows for the speed of the conveyor to be increased. The present invention is suitable for use with a conveyor apparatus used with a truck and commonly known as a "stone slinger".

Title: Phonospirometry for non-invasive monitoring of respiration
Inventor: QUE CHENG-LI
IPC: A61B5/091
Filed: 1999-02-22
Abstract: To compensate for the poor signal-to-noise ratio when transforming a patient tracheal sound signal into a respiration flow signal, the transformed signal is used when the sound signal is above a threshold, and interpolated values are used when the sound signal is below the threshold. A volume of breath signal is reliably obtained. Respiration start/stop is detected either by analyzing the sound signal or by physical measurement of the patient. A wearable device incorporating the sound signal processing method can provide an immediate indication or alarm when the volume of breath signal indicates a condition requiring medical attention.
