Patent CA-2204682-C (CA)
Inventor: PATTERSON HAROLD E
IPC: B65G27/30
Filed: 1997-05-07
Granted: 2004-07-20
Abstract: A base excited vibratory trough conveyor includes a trough mounted on leaf springs to a base which is excited by a linear vibratory drive. The vibratory drive produces a linear force which is oriented to be perpendicular to the springs, and the linear force is adjusted to equal the reaction force of the springs on the base during the desired stroke. Such balancing results in no stroke or movement of the base. A more lightweight base can thus be used without requiring that the base center of gravity be aligned along the center of gravity of the conveyor and the trough, or that the base be excessively heavy.

Title: Filter with temperature compensated tuning screw
Inventor: ZYBURA ANDRE J
IPC: H01P1/208
Filed: 1997-06-02
Granted: 1999-01-19
Abstract: A temperature compensated filter has a compensating screw mounted in a support in the wall of a cavity.  The support is made from a material having a high coefficient of thermal expansion compared to the material of the cavity and the material of the compensating screw.  As temperature changes, the support moves the compensating screw either further into the cavity or further out of the cavity to compensate for the change in resonant frequency of the cavity that would otherwise occur.  The compensating screw can be used with single, dual or triple mode cavities.  The compensating screw can be made of metallic material or it can be made of non-metallic material with a metallic outer surface.  The compensating screw is locked in the support before the support is inserted into the wall of the cavity.  The support is then locked in the wall of the cavity and the screw automatically changes position within the cavity as temperature changes.  An RF barrier can be used to prevent RF energy from the cavity from entering the area of the support.

Abstract: The air diffuser of this assembly has a top collar with a free edge and the damper is of conventional construction, having a central core and a set of radially outwardly extending strut arms. In the central core is mounted a vertical actuating screw for adjusting the air deflector blades of the damper. The outer ends of the strut arms are formed with a stop member resting over the top edge of the diffuser collar and with a system to deform the collar walls so as to lock the strut arms to the collar against axial movement and against rotation. The stops serve to locate the damper in its proper operative position so as to direct the air uniformly over the air diffuser baffles.

Granted: 2000-01-11
Abstract: Ce piège à animal est du type comprenant deux cadres métalliques connectés un à l'autre par deux pivots coaxiaux. Ces cadres définissent deux paires de mâchoires pouvant se déplacer sous l'effet de ressorts de torsion, entre une position ouverte où les mâchoires d'une même paire sont éloignées l'une de l'autre, et une position fermée où elles sont à proximité l'une de l'autre. Un crochet de maintien est fixé à la barre de frappe de l'une des mâchoires en vue de retenir celle-ci à la mâchoire adjacente lorsque le piège est en position ouverte. Une détente est également prévue pour libérer le crochet et permettre aux mâchoires de se refermer sous l'action des ressorts. Selon l'invention, le crochet de maintien est fixé à la barre de frappe qui lui sert de support au moyen d'une attache pivotante consistant en une plaque mince repliée et enroulée autour de la barre de frappe. Cette plaque s'étend à plat autour de la barre de frappe et réduit les risques possibles d'endommagement à la fourrure de l'animal capturé. Avantageusement aussi, les bras des mâchoires ont des extrémités supérieures repliées à angle de façon à diverger des plans dans lesquels ils s'étendent dans des directions permettant aux barres de frappe de chacune des paires de mâchoires de venir en contact l'une contre l'autre et ainsi éviter d'infliger une souffrance prolongée à l'animal capturé.

Title: Network access in multi-service environment
Inventor: FOCSANEANU MIHAI
IPC: H04L29/00
Filed: 1998-02-25
Granted: 2006-10-10
Abstract: In current voice telephony, CATV, and wireless networks, traffic is channelized for both access and transport. This channelizationis wasteful of resources where multiple services have varying demands for bandwidth and holding times, or a service generates traffic that is bursty in nature. The invention solves these problems by providing flexible and adaptable multi-service access to the networks. Customer requirements are checked by monitoring traffic on a local access at a connection request and/or during the established connection, and the local access is configured according to the transmission requirements. The local access can also be configured in response to the network information. In furhter realizations, either or both the CPE connector and access module include common bus architecture which forms a backbone LAN for handling a multiplicity of CPEs and/or networks.
