Patent CA-2184555-A1 (CA)
Inventor: FARRINGTON RICHARD I
IPC: D06F75/18
Filed: 1996-08-30
Abstract: A steam surge system with a reservoir, a pump, a conduit and a seal.  The seal is located at an entrance to a steam chamber of an iron.  The conduit connects an outlet of the pump  to  the  steam  chamber  entrance  by  passing  water through the seal.   The seal prevents steam from exiting the steam chamber entrance and has a slit to allow water to pass through the seal into the steam chamber.  The seal prevents water from passing through the slit unless the pump is being actuated.

Title: Encryption system for mixed-trust environments
Inventor: FORD WARWICK STANLEY
IPC: H04L9/06
Filed: 1996-09-27
Abstract: Encryption frequently needs to be used in communication networks which span different geographical regions which can be considered to be trusted to different extents. According to one embodiment, the invention uses both a strong encryption algorithm and a weak encryption algorithm. A device in the high-trusted region can encrypt using the strong algorithm and can decrypt using either the strong or weak algorithm. A device in the low-trusted region can decrypt with either the strong or the weak algorithm but can encrypt only with the weak algorithm.
Patent CA-2187585-A1 (CA)
Inventor: EBERLE FREDERICK P
IPC: B60K17/10
Filed: 1996-10-10
Abstract: A mechanical disconnection mechanism for a hydrostatic transmission. The output shaft of the hydrostatic transmission is divided into a drive portion and a driven portion, with both the drive portion and the driven portion being provided with external splines or gears. To connect the drive portion to the driven portion, a splined sleeve is positioned to engage the splines of both the driven portion and the drive portion such that rotation of the drive portion rotates the driven portion. To disconnect the drive portion from the driven portion, the splined sleeve is positioned to engage only one of the drive portion and the driven portion. In the disconnected position, the implement may be manually pushed without reverse driving the hydraulic unit of the transmission to thereby allow for relatively easy movement. A brake is mounted about the driven portion of the output shaft to enable the vehicle to be stopped regardless of the position of the splined sleeve.

Abstract: Procédé de conversion d'acide sulfhydrique contenu dans un courant gazeux d'alimentation en soufre élémentaire et en hydrogène. Selon ce procédé, on met en contact un courant gazeux d'alimentation contenant de l'acide suflhydrique avec un solvant organique polaire ayant une quinone et un agent complexant dissous dans celle-ci. L'agent complexant doit avoir une valeur pK¿b? inférieure à 13,0 environ. La réaction de l'acide sulfhydrique dans le courant gazeux d'alimentation avec la quinone se traduit par une augmentation de la conversion de quinone en hydroquinone à des basses températures de réaction et des pressions partielles de H¿2?S, et par une augmentation de la récupération de soufre. En outre, la présence d'un agent complexant augmente la sélectivité de production d'hydrogène dans la déshydrogénation de l'hydroquinone en quinone et en hydrogène.

Title: External Power Source to Main Battery Power Source Switch
Inventor: BARKAT SHAKIL H
IPC: H04B1/44
Filed: 1997-03-05
Abstract: A switching circuit (30) in a portable telephone connects a gate of a field-effect transistor (Q1) to a voltage below the transistor's gate threshold voltage when the voltage at a first power source terminal (B) falls below a threshold voltage, thus disconnecting the first power source terminal (B) from a portable telephone power input terminal (B+) and connecting a second power source terminal (A) to the power input terminal (B+). The threshold voltage is set at a voltage above the minimum supply voltage of the portable telephone. The first power source terminal may be connected to a main battery and the second power source terminal may be connected to an adapter such as a battery eliminator adapter, hands-free adapter, or mobile transceiver adapter. This switching circuit prevents a call in progress from being disconnected when power sources are exchanged during a GSM burst.

Title: Improved variable frequency drive reflected wave suppressors
Inventor: FUNKE JAMES
IPC: H02H9/00
Filed: 1997-05-28
Abstract: The invention provides a circuit to protect an AC motor powered by a Variable Frequency Drive (VFD) from overvoltages caused by reflected waves. A full wave bridge rectifier circuit across the lines of the motor to be protected provides rectified voltage output to a capacitor, across which a low resistance discharge resistor in series with one or more zener diodes is attached. When an overvoltage above the clamping voltage of the zener diode(s) occurs across the protected lines, the zener diode(s) will conduct, causing the excess charge across the capacitor to discharge through the resistor until the voltage drops below the clamping voltage of the diode(s).
