Patent CA-2061294-A1 (CA)
Inventor: PEREGO LUCIANO
IPC: G11B15/60
Filed: 1992-02-17
Abstract: In an automatic cassette loading machine a pancake is mounted on a rotatable support hub.  A reading member comprising a photoelectric cell and carried by a main carriage movable at right angles to the axis of the pancake is disposed at a position spaced apart from the pancake itself and is then moved close to the latter.  When the peripheral edge of the pancake is intercepted by the light beam emitted by the photoelectric cell the reading member is moved away from the pancake and disposed so that it can intercept the passage of a closure tab fastening the end of the tape on the pancake.  The pancake rotation is then stopped when the location of the closure tab enables it to be picked up by a grasping member associated with the cassette loading machine.

Inventor: GROEHL LAWRENCE R
IPC: G01R31/36
Filed: 1992-03-20
Abstract: Defective battery cells are detected by individually monitoring the voltage output therefrom, which characteristically becomes abnormal when the defective condition occurs. Each cell is independently referenced to a common ground by its voltage monitoring device which drives a level sensing comparator that generates a control signal when the output voltage from that cell becomes abnormal. This control signal drives at least one switch to indicate when the defective condition occurs.

Patent CA-2068830-A1 (CA)
Title: Laser compass
Inventor: WILLETTS MILES D
IPC: G01C15/00
Filed: 1992-05-15
Abstract: LASER COMPASS Abstract of the Disclosure A laser compass projects a laser beam along an axis.  A mirror is rotated within a rotation plane perpen-dicular to the axis.   The mirror is pivotally adjusted relative to the axis of the laser beam to reflect the laser beam at an angle ".alpha.".  As the mirror rotates, the reflected laser beam is swept through an inverted cone having an apex at the point of intersection of the laser beam with the mirror, and having a base on whatever projection surface happens to be located above the laser compass (typically, a ceiling).  The base of the cone defines a perfect circle on the projection surface.  The radius "r" of the circle is governed by the distance "d" between the projection surface and the intersection of the laser beam with the mirror; and, by the angle .alpha..  The mirror pivot angle .alpha. re-quired to yield a circle of desired radius "r" is given by the formula:                        tan .alpha. = r/d The circle projected onto the projection surface may be used as a template to construct an accurate, curved pattern on the projection surface, or as an aid in the building of cylindrical or conical-shaped structures.

The angle is selected to allow the seat and back assembly to be selectively positioned in the generally fully forward or the generally fully reclining positions without reliance on a locking device to maintain the position thereof.
Patent CA-2081381-A1 (CA)
Inventor: VOWLES BRUCE CAMPBELL
IPC: F03B13/18
Filed: 1992-02-10
Abstract: On décrit un appareil et un procédé permettant de transformer le mouvement des vagues dans une masse de liquide en énergie utilisable. L'appareil comprend une structure rotative flottante ou fixe (5), un ou des bras à levier (2) maintenus pivotants par la structure de support, et un ou des suiveur(s) de vagues (1) fixés à l'une des extrémités du ou des bras à levier et mis en position sur la masse de liquide. Le bras à levier est relié à un dispositif de transfert d'énergie par exemple à une bielle (7) qui déplace une charge en fonction de l'action des vagues sur le suiveur à vagues. Ledit suiveur possède une partie supérieure (23) en matière flottante, et une partie inférieure (24) en forme de chambre creuse (24a), ouverte au fond (24b), la face tournée vers la mer (27a) étant disposée sous un angle permettant de capter l'énergie latérale de la vague. Le fond ouvert permet à la chambre de se remplir de liquide lors de la montée de la vague. Lorsque celle-ci retombe, la dépression créée par la fermeture d'une soupape (10) située dans la partie supérieure, avec l'aide de l'adhérence superficielle, freine le reflux du liquide hors de la chambre, de sorte que le suiveur de vagues est tiré vers le bas par le poids du liquide présent dans la chambre. Lors de la remontée de la vague, de l'énergie hydraulique est transmise à la partie flottante supérieure (23) par l'intermédiaire du liquide contenu dans la chambre à fond ouvert, ce qui provoque la remontée du suiveur de vagues. Des panneaux s'étendant vers la mer, verticaux et formant un entonnoir (4) canalisent la vague vers le haut et vers le bas en direction du suiveur de vagues, amplifiant ainsi la hauteur de la vague.

Title: Adaptive feed-forward method and apparatus for amplifier noise reduction
Inventor: TALWAR ASHOK K
IPC: H03F1/32
Filed: 1992-11-23
Abstract: An adaptive feed-forward cancelling system obtains a reference signal and a sample signal from an amplifier by directional couplers.  The sample signal essentially consists of an undistorted input signal component and a noise and distortion component.  The reference and sample signals are provided to an adaptive interference canceller which performs an adaptive cancellation process.  The interference canceller provides a cancellation signal essentially consisting of the signal component which is common to both the reference signal and the sample signal.  The cancellation signal is injected into a transmission line which carries the sample signal so that only an error signal remains which essentially consists of the noise distortion component of the amplifier output signal. the error signal is then amplitude and phase adjusted to have substantially the same amplitude and to be substantially 180° out of phase with the amplifier output signal.  The amplitude and phase adjustment error signal is then injected by a directional coupler onto the transmission line which carries the amplifier output signal so that an amplified input signal is provided by the power amplifier without the noise and distortion components added by the amplifier.

Patent CA-2101631-A1 (CA)
Inventor: FISHER DANIEL E
IPC: C01B32/40
Filed: 1992-02-27
Abstract: The present invention is directed to a method for producing high purity carbon monoxide. In the method, a hydrocarbon feed stock and import carbon dioxide are introduced into a reaction system containing a primary reformer and a secondary re-former. The hydrocarbon feed stock, import carbon monoxide and recycle carbon monoxide are passed through the primary re-former while being heated to a temperature sufficient to reform the feed stock into a first carbon monoxide reaction product. The first reaction product and oxygen are fed into the secondary reformer. The first reaction product is reacted in the secondary re-former in an autothermal reation to provide a second carbon monoxide reaction product having a lower hydrocarbon level than the first reaction product. The second reaction product is removed from the secondary reformer at a second predetermined tem-perature and a high purity carbon monoxide is recovered from the second reaction product without the use of cryogenic separa-tion techniques.
