Patent CA-2189718-A1 (CA)
Inventor: TSUMURA SOICHI
IPC: H03F3/20
Filed: 1996-11-06
Abstract: A power amplifier system which makes it possible to reduce the power consumption at a low power output and to stably change the output power within a wide range. This power amplifier system includes a first power amplifier unit having a fixed gain, and a second power amplifier unit having a fixed gain, both of which are connected in cascade. The first amplifier unit receives and amplifies an initial input signal and outputs a first output signal.          The second amplifier unit receives and amplifies the first output signal and outputs a second output signal. A supply voltage controller serves to control the supply or stop of a power supply voltage to the first and second amplifier units in response to a control signal. The output selector serves to select one of the first and second output signals and to output the selected signal as an output signal of the power amplifier system in response to the control signal. For low power level, only the first amplifier unit is activated and the first output signal is outputted as the output signal of the system. For higher power level, the first and second amplifier units are activated and the  second output signal is outputted as the output signal of the system.

The appliance has a control system that monitors and controls all of the components of the appliance. The control system can be activated so that it prevents all visual displays and audible alarms from being actuated by the user during the Sabbath. The control system also prevents any actions of the user from causing the machine to do work.
Patent CA-2190630-A1 (CA)
Title: Call setup and service invocation in telecommunications networks
Inventor: LOBLEY NIGEL
IPC: H04M3/42
Filed: 1995-06-21
Abstract: A telecommunications network has switching means (12) configured such that a request from a first network termination (10) to establish a communications link with a second network termination is directed to the service processing means (13) which directs the switching means (12) to establish the link. This enables the user terminal (10) to direct service and call setup requests directly to the service processing means (13), the switch (12) not being involved with the call or service request until the service processing means (13) instructs it to participate, thereby minimising the establishment and allocation of resources until it is clear that such resources are required. A call can therefore be validated before any communications links are established, thus potentially offering economies in the operation of the system.

Inventor: JACKO MICHAEL S
IPC: B26D3/22
Filed: 1995-05-30
Abstract: An apparatus for cutting a food product is disclosed which utilizes a cutting wheel having a plurality of knives (38) extending between a hub (34) and a rim (36) in conjunction with other cutting knives to produce a multi-dimensional cut of the food product. A circular knife (52) may be located upstream of the cutting plane defined by the cutting wheel such that the rotary knife longitudinally cuts the food product before it passes through the cutting plane. The apparatus according to the invention also utilizes separate drive motors for the feed conveyor and for the cutting wheel. In order to prevent deflection of deformation of the larger cutting wheel, a rim stabilizer (60) engages the cutting wheel rim to prevent any deflection of the rim which may cause deflection of the cutting knives as the cutting wheel rotates.

Inventor: NOURRCIER CHARLES E
IPC: G01S17/18
Filed: 1996-12-03
Abstract: An improved circuit and method of making precise time of arrival measurements on optical pulse data of relatively varying widths.     The  invention  provides  an  analog  input  pulse representing received optical pulse data, along with a delayed version of the analog input pulse.  The time of delay is set such that the original analog pulse and the delayed analog pulse cross each other  at  a  predetermined  point.    This  cross-over consistently occurs at the same point on the signal independent of the size or shape of the analog pulse.  Preferably, the cross-over occurs at approximately 70 % of the analog pulse amplitude. The cross-over point between the original pulse and the delayed pulse triggers the generation of the leading edge of a time of arrival pulse.
Patent CA-2192476-A1 (CA)
Inventor: BOLAND BERNHARD
IPC: A61C17/24
Filed: 1996-03-14
Abstract: The invention is directed to an electrically powered dental cleansing apparatus (1) in which a cleansing implement (19) is coupled to a drive sleeve (11) and adapted to be rotated about a longitudinal axis (4).  According to the invention, the coupling is effected by means of a resilient element, in particular a spring (21) which includes a slip coupling (27) and/or a buffer zone (28). Under normal conditions, the slip coupling (27) pro-vides a non-rotative connection between the drive sleeve (11) and the cleansing implement (19). However, in the event of the cleansing implement (19) seizing in an interproximal space, for example, the slip coupling (27) will slip, thus avoiding poten-tial damage. The buffer zone (28) acts to prevent displacement of the cleansing implement (19)--although intended by the user--in cases where, for example, the cleansing implement is posi-tioned against a tooth surface rather than against an interprox-imal space.

Abstract: Ensemble transducteur ultrasonore (20) pour un soudage par ultrasons hygiénique. L'ensemble comporte une zone de soudage par ultrasons hygiénique et une zone non hygiénique séparées par une paroi barrière (88). Cette paroi barrière présente une ouverture qui permet au convertisseur ultrasonore (186) de se déplacer en va-et-vient à travers celle-ci. De plus, un dispositif situé dans la zone non hygiénique de la machine fait vibrer ledit convertisseur ultrasonore (186), lequel envoie ces vibrations à la zone hygiénique de la machine. Le convertisseur présente une zone nulle (192) au niveau de laquelle il vibre sensiblement au minimum, et d'autres zones qui vibrent de manière nettement plus importante. Une surface de soudage (194) généralement cylindrique est fixe par rapport à la zone nulle du transducteur. Cette surface de soudage est essuyée par un joint essuyant (202) monté sur le bord de l'ouverture. Ces deux parties peuvent également être inversées.
Patent CA-2199724-A1 (CA)
Title: Double helix antenna system
Inventor: WALLACE RAYMOND C
IPC: H01Q1/36
Filed: 1996-06-17
Abstract: A double helix antenna (10) comprised of orthogonally-wound helix conductors.  The double helix antenna (10) includes a first helix conductor (14) wound in a first direction about a vertical axis, V, of the double helix antenna (10). A  second helix conductor (18) is wound in a second direction about the vertical axis, V. In a specific implementation, the first and second helix conductors (14 and 18) are of different lengths, respectively corresponding to first and second frequency bands. Additionally, the first and second helix conductors (14 and 18) are wound so as to be orthogonal at those horizontal planes within which the first and second helix conductors (14 and 18) intersect or are otherwise minimally separated in the horizontal dimension. This orthogonal winding relationship between the helix conductors substantially reduces mutual coupling, thus enabling operation of separate helical antennas in close physical proximity.

Title: Method of reducing the bubble formation when curing a room temperature vulcanizable silicone sealant composition containing silicon-bonded alkoxy crosslinker in a confined configuration
Inventor: CARBARY LAWRENCE DONALD
IPC: C08L83/06
Filed: 1997-03-20
Abstract: A method is disclosed of forming a seal between two or more non-porous substrates by adding an oximosilicon compound to a prepared room-temperature-vulcanizable silicone sealant composition which is comprised of an alkoxy ended polydiorganosiloxane, a crosslinker having silicon-bonded methoxy or ethoxy, a filler, a titanate catalyst, and by-produced methanol or ethanol that is obtained during the manufacture of the silicone sealant composition, applying the sealant composition, to at least two non-porous substrates forming an assembly of an uncured sealant composition bonding them together, subjecting the assembly to conditions which would ordinarily formdetrimental bubbles if the oximosilicon compound were not present, and completely curing the composition to form an assembly of at least two non-poroussubstrates bonded by cured sealant that is essentially free of detrimental bubbles. Such a method is valuable in forming gaskets which are used in the internal combustion engine industry.
