Title: Motor operator for electrical switches
Inventor: GULA LANCE
IPC: H01H9/28
Filed: 1997-04-14
Abstract: A motor operator unit for an electrical switch is pivotally mounted on a bracket to swing between a closed, operative position in which an actuator in the motor operator unit engages the switch handle for electrical operation of the switch handle and an open position in which the switch handle is freely accessible for direct manual operation. The compliant actuator which is translated by a motor driven threaded shaft overtravels at each end of its reciprocal path after actuation of the switch handle to toggle a single power switch which determines both direction and shutoff of motor operation. A lockout plate mechanically prevents electrical and manual operation of the switch handle and carries an interlock switch which only enables motor operation when the motor operator unit is in the operative position and not locked out. The actuator is configured to prevent full rotation of the motor operator to theoperative position, if the position of the actuator, which is virtually identified by indicators, does not correspond to handle position.

Patent CA-2207121-A1 (CA)
Title: Modem
Inventor: SARAT JEAN-MARC
IPC: G06K19/07
Filed: 1996-09-24
Abstract: The invention relates to modems designed to allow transmission of data between a terminal (a personal computer or PC) and a network. To improve the operating versatility of a modem or its utilization by a smartcard, the modem is equipped according to the invention with a receptacle (80) for receiving a smartcard (120), with a connector (110) for this card and a card interface circuit (100), and the microcontroller (50) of the modem (the microcontroller controlling communication with the network when commanded by the PC) also controls the card interface circuit. This microcontroller thus constitutes the kernel of the modem and at the same time the kernel of a card reader. The communication with the card is effected by commands known as "AT' and the systematic prefix sequence "AT' (whereby the microcontroller recognizes that it has to carry out an operation) is followed by a second systematic prefix sequence if a communication operation between the terminal and the card is to be effected. The second prefix sequence is "+G'.

Patent CA-2211231-A1 (CA)
Title: Distortion compensation control for a power amplifier
Inventor: MCNICOL JOHN DUNCAN
IPC: H03F1/32
Filed: 1997-07-23
Abstract: A control arrangement and method for controlling a gain and phase adjuster used for controlling the gain and phase of a compensation signal for compensating for the distortion produced by a power amplifier is disclosed.  The control arrangement makes use of a reference signal, of known frequency, which is amplified along with the desired carrier signals.  The reference signal component of the amplified signal is then isolated and a comparison is made, either with the actual reference signal, e.g., by a QAM demodulator, or alternatively with the known frequency of the reference signal, e.g., by a FM discriminator, in order to determine the differences in gain and in phase of the reference signal component of the amplified signal in comparison with the reference signal.  For example, a QAM demodulator is used for producing a first difference signal indicative of the phase switch difference, and a second difference signal indicative of the gain switch difference. These signals are then correlated with the signal envelope of the main signal in order to produce signals indicative of the sign and magnitude of the control signals used to adjust the gain and phase adjuster in a feed back loop.

Patent CA-2222819-A1 (CA)
Title: Method and device for producing and utilizing gas from waste materials
Inventor: MARTIN JOHANNES JOSEF EDMUND
IPC: F23G5/46
Filed: 1997-11-28
Abstract: In this process for gasifying and burning waste materials, the waste materials are introduced into an incinerator (1) and end up on a burning grate (6) to which air is conducted by means of various undergrate forced draft chambers (8a to 8e). In the first area air is introduced at a superstoichiometric level in order to ignite the waste materials. Then, via the undergrate forced draft chambers (8c to 8e), oxygen is mixed into the air which is used for the gasification, at the same time establishing a substoichiometric level which leads to gasification of the waste materials. These combustible gases which come about in the process pass via the waste gas flue (12) into a second furnace (2), in which the gases are burned at a superstoichiometric level through the introduction of combustion air. The resulting waste gases pass to a heat exchanger (3).             (Figure)

Patent CA-2230515-A1 (CA)
Inventor: SIMMET CHRISTIAN
IPC: A61D19/02
Filed: 1998-02-25
Abstract: An insemination catheter (1), specially for sows, is described, comprising a tubular shaft portion (2) with a shaped body portion (3) at its distal end, the body portion having larger diameter dimensions than the shaft. Said shaped body portion (3) consists of a series of disc-like radial laminae or of narrow turns of a helix of one slim basically radial lamina (11,17) attached to the shaft (2) in mutual distance of the lateral faces of its radial neighbor laminae or turns, these faces facing along the axis. The laminae have an envelope surface (13) forming the shape of said body portion, and the ratio of the thicknesses of these laminae or turns to the distances between these parts is within the range of 5 : 1 to 0.5 : 1. By this pack of slice-like laminae, the technology is improved in several respects. The lamination results in a considerable reduction of materials, in a better fixation of the catheter in the cervix, in a better sealing of the cervical canal during the insemination due to the fact that the individual laminae go closer to the rings of the cervical canal and that due to their elasticity, they may be used as well for young and old sows, and also results in a better stimulation of the cervix, thus creating a good stimulus of the uterus muscular system and therefore reaching a better semen transport by the wave-like contractions and sucking action.
