Title: Internetwork communication system for managing subscriber switches between networks
Inventor: FUKAZAWA SHIGERU
IPC: H04Q3/00
Filed: 1993-09-03
Abstract: A communication system in which, a subscriber terminal moves between networks having different number plans is described.  The moved subscriber terminal can receive the same service as that of the network from which the subscriber terminal has moved (movement originator network) without being conscious of the movement. In the system, when the subscriber terminal moves between the networks having the different number plans, the movement of the subscriber terminal is registered in the network to which the subscriber terminal has moved (movement destination network), data is exchanged with the movement originator network, an allocated number correlative table is prepared and stored in the movement destination network; while, a movement destination number correlative table is prepared and stored in the movement originator network. When the moved subscriber terminal issues a call to another network, a call control is transferred from the movement destination network to the movement originator network on the basis of the allocated number correlative table and carried out in the movement originator network on the basis of the movement destination correlative table.
Patent CA-2107140-A1 (CA)
Inventor: KIESERLING CLAUDIA
IPC: A63B71/14
Filed: 1993-09-28
Abstract: A glove is provided for enhancing the fit around a hand inserted therein.  The glove has a fit adjusting mechanism attached to one or more adjusting strips via a adjusting cable element which has a variable effective length.  The adjusting strip or strips extend substantially circumferentially around the base of the glove.  As the adjusting mechanism is turned, the effective length of the cable element is shortened thereby cause the closed loop of the strip and cable element to contract around the hand inserted in the glove.  As a result, the fit of the glove around the hand is enhanced.

Patent CA-2111239-A1 (CA)
Inventor: DUNCAN IAN JAMES
IPC: B63H9/06
Filed: 1992-06-11
Abstract: 2111239 9222396 PCTABS00018 The present invention relates to wind powered or assisted craft, particularly hydrofoil craft, which are capable of travelling considerably faster than wind speed over a wide range of wind speeds and directions. The invention has application from single person leisure and sports craft through to large commercial cargo and passenger vessels, although certain aspects of the invention will find application to wind powered or assisted craft or vehicles for use on land and to hydrofoil supported craft in general. Whilst in the case of smaller craft, wind power may provide the sole means of propulsion, in the case of larger craft the provision of auxiliary power sources is likely, as an aid to low-speed man uvring and operation in unfavourable wind conditions. Heavier craft may well require the assistance of such power sources to get through the ''resistance hump'' which is characteristic of hydrofoil craft.

Title: Electrothermal actuator
Inventor: PETOT BRADFORD W
IPC: F03G7/06
Filed: 1994-01-14
Abstract: An electrothermal actuator includes a housing containing a working fluid and a heater disposed in the fluid within the housing.  A piston is slidably disposed in the housing for movement in response to heating and cooling of the working fluid.  An output member is coupled to the piston and movable between first and second positions for transmitting a drive force from the piston to a load.  A latch mechanism is operatively connected to the output member for releasably latching the output member in the second position without continuously heating the working fluid.

Patent CA-2118057-A1 (CA)
Title: Metal halide electronic ballast
Inventor: NERONE LOUIS R
IPC: H05B41/282
Filed: 1994-10-13
Abstract: METAL HALIDE ELECTRONIC BALLAST            ABSTRACT OF THE DISCLOSURE        An electronic ballast can be connected between either a DC power supply or an AC power supply and a gas discharge lamp, such as a metal halide lamp and control the electrical power supplied thereto.    An inverter receives a DC power and generates a periodic waveform at  a controlled  frequency.     A resonant circuit is connected to the  inverter and tuned to resonate at a predetermined frequency and generate an output voltage.    A coupling capacitor is connected between the resonant circuit and the discharge lamp and supplies the output voltage of the resonant circuit thereto.   A controller sets the frequency of operation of the inverter near the resonant frequency of the resonant circuit.   The controller is responsive to at least a predetermined set point control voltage and to the output voltage of the resonant circuit.     The resonant circuit is tuned to increase the voltage from the inverter means to a level sufficient to cause the discharge lamp to enter a glow mode of operation.   The coupling  capacitor  and  resonant  circuit  have  an appropriate impedance to maintain sufficient power flow to the discharge lamp to carry it through the glow mode of operation, into an arc mode of operation and to a steady-state mode of operation.

Patent CA-2127042-A1 (CA)
Inventor: HEER DANIEL N
IPC: H04M1/68
Filed: 1994-06-29
Abstract: A security node disposed in the telecommunications network connecting calling and called parties transforms information (which can be voice, data, facsimile, video and other types of calls or messages) encrypted in a first format to (a) encrypted information in a different format or to (b) non-encrypted information, and vice-versa. The node is accessible from any location connected to the network. By routing calls or messages originated by the calling party and destined for the called party via the security node, and providing appropriate control signals to the node, the information may be encrypted only over a portion of the transmission path between the parties, and clear over the remainder of the transmission path. Alternatively, the information may be encrypted in different portions of the path using different encryption algorithms. This arrangement enables the parties to obtain relatively secure communications even if only one party has a security device at the originating or terminating end, or if the parties have security devices using different handshaking protocols and encryption algorithms.
