Patent CA-2104182-C (CA)
Inventor: DOBROVOLNY PIERRE
IPC: H04N5/44
Filed: 1993-08-16
Granted: 1999-03-30
Abstract: A double conversion tuning system for a high definition television receiver includes a microprocessor supplying first and second digital numbers to first and second local oscillators. The first local oscillator is controlled by a wide band phase locked loop that includes a programmable divider that receives the first digital number from the microprocessor and a prescaler that couples the first local oscillator signal to the programmable divider. The output of the programmable divider supplies one input of a phase detector, the other input of which is supplied with the divided down output of a crystal reference source. The output of the phase detector controls the first local oscillator frequency. The tuning of the first local oscillator is coarse and the first IF signal frequency may deviate within a predetermined range from a desired value. The second digital number from the microprocessor controls, via a D/A and varactor, the resonant frequency of a tunable dielectric resonator in the second local oscillator to adjust the second local oscillator frequency to compensate for the deviation in first IF signal frequency so that the second IF signal frequency remains constant.

Patent CA-2127654-C (CA)
Inventor: KIRSCHNER MARK J
IPC: D21C9/10
Filed: 1994-07-08
Granted: 1995-11-28
Abstract: An oxygen delignification method and apparatus in which a charge of heated wood pulp is reacted with oxygen in the presence of a charge of caustic soda in a plurality of reaction stages located between mixing stages in which caustic is mixed with the wood pulp. The use of the plurality of mixing stages reduces peak pH exposure of the wood pulp that would otherwise occur if the charges of caustic and wood pulp were mixed all at once. Moreover, the caustic mixed in such manner replenishes neutralized caustic and ensures that the average pH level is increased above that in conventional oxygen delignification. The increase in average pH level favors an increase in the delignification. Filtrate from a washing stage is introduced into the mixing stages to prevent wood pulp degradation. Oxygen is mixed within the wood pulp by a wood pulp mixer that employs coaxial perforate passageways between which the wood pulp is retained and driven but which allow the oxygen to pass in an inward radial direction of the passageways to mix with the wood pulp.

Title: Device for processing synthetic thermoplastic material
Inventor: BACHER HELMUT
IPC: B29B17/00
Filed: 1993-03-16
Granted: 1997-11-25
Abstract: A device for pre-processing a synthetic thermoplastic material, such as polyester waste, comprises at least two containers connected in series, in each of which a comminuting and  mixing tool rotates at the base of the containers about a vertical axis.  At least the downstream container has an evacuation duct which can also be used to introduce an inert gas if required.  The containers are connected by a sleeve in which there is a stop valve to facilitate trouble free maintenance of the vacuum in the downstream container until the valve is opened, thus allowing the vacuum in the container to draw in the material in the upstream container.  In the upstream container (as seen in the flow-direction of the material), the material in pre-comminuted, pre-heated, pre-dried and pre-compacted and that process is enhanced by the turbulence in the material as it is sucked into the downstream container.  Completely homogenous material is thus transported for further processing by a worm which is connected to the last container.

Abstract: Un agencement d'un dispositif de commutation électrique utilisé dans la protection contre les arcs électriques comprend un mécanisme déclencheur, un support de contact fixe, un support de contact mobile, un orifice d'évacuation, un conducteur d'arc et une barrière d'extinction d'arc. Sur le support de contact fixe est monté un contact fixe et sur le support de contact mobile est monté un contact mobile. En réponse à un état de courant de surcharge, le mécanisme de déclenchement fait tourner le support du contact mobile, qui passe d'une position fermée à une position ouverte, ce qui génère un arc électrique. En position fermée, le contact mobile rejoint le contact fixe, et en position ouverte, le contact mobile est séparé du contact fixe. La barrière d'extinction d'arc est composée d'un matériau de dégazage et est située entre le contact fixe et une partie du mécanisme de déclenchement. Le contact fixe est placé généralement entre la partie du mécanisme de déclenchement et le conducteur d'arc de sorte que celui-ci écarte l'arc électrique de la partie du mécanisme de déclenchement. L'orifice d'évacuation est généralement placé dans le prolongement du sens initial de déplacement du contact mobile lorsque le support du contact mobile commence à tourner et à se déplacer d'une position fermée à une position ouverte.
