Patent CA-2233709-C (CA)
Inventor: LEE DAVID D
IPC: H04N7/52
Filed: 1996-10-01
Granted: 2001-07-31
Abstract: The transmission of digital video data is accomplished using a block coding scheme, which embeds timing and control signals into the data stream. The code is DC balanced, achieved by selectively inverting some data blocks, as a function of the cumulative disparity; and the transitions within each block are controlled, providing either a minimum number of transitions per block, or a maximum, and this is achieved by selectively inverting certain bits within a block. The use of low-swing differential transmission minimizes electromagnetic interference (EMI).
Patent CA-2234696-C (CA)
Inventor: SLOCUM RAY G
IPC: A23L3/10
Filed: 1996-10-15
Granted: 2005-07-26
Abstract: L'invention concerne un contenant à fines parois facilement écrasable (11), dont le fond fait partie intégrante ou dont le fond est une partie rapportée par soudure, et qui renferme un produit comestible (10) devant être stérilisé. Le contenant vide est doté d'une extrémité rapportée ou intégrée pouvant avoir une pente concave par rapport à la structure interne. Un gaz inerte liquéfié ou solidifié est ensuite introduit dans le contenant que l'on ferme hermétiquement au moyen d'une extrémité à forme concave (13) avant la vaporisation complète du gaz inerte liquéfié ou solidifié. Les extrémités ne subissent aucun renflement sous l'effet de la pression induite par la stérilisation, cette pression étant imputable à l'effet de la mise sous pression du gaz inerte et suffisant à compenser le vide engendré par le refroidissement de la vapeur d'eau (chaude) au-dessus du produit comestible. Le système de pression en question permet d'obtenir la rigidité requise.

Title: Tapered screen assembly for a cellulose pulp digester
Inventor: JOHANSON JERRY R
IPC: D21C7/00
Filed: 1998-08-28
Granted: 2004-06-22
Abstract: A comminuted cellulosic fibrous material treatment vessel assembly includes a substantially vertical vessel having a top, bottom, and outlet, and through which the material flows in a flow direction. The vessel preferably has a substantially cylindrical wall with at least one diameter changing transition between the inlet and the outlet. A screen assembly is preferably provided at or just past the transition. The screen assembly comprises one or more annular screen surfaces diverging in the flow direction of the material, the angle of divergence being between about 0.5-10° to the vertical, and preferably substantially continuous.  Providing such a screen assembly reduces the radial compression of material thereon, and increases the volume and rate of liquid that can flow through the material and be removed through the screen surface compared to a non-diverging screen surface (that is a right-cylindrical surface). The screen surface has openings of substantially uniform size, and preferably with a substantially uniform percentage of open area, in the flow path.

Title: Adjustable mobile machine base systems and methods
Inventor: BALOLIA SHIRAZ
IPC: B62B5/00
Filed: 1999-03-26
Granted: 2002-08-06
Abstract: An adjustable mobile base that accommodates machines of different effective footprints and allows them to be selectively moved from place-to-place or fixed at a given location. The mobile base assembly comprises a frame assembly comprised of corner members and side members. The side members are telescopically received within the corner members such that a width dimension and depth dimension of the base assembly can be changed to accommodate machines having different effective footprint. A lock system may be provided which employs one or more lock assemblies. Each lock assembly comprises a lock member that is slidably received within a lock housing and a drive member which is threadably received within the lock housing. Rotating the drive member in one direction elevates one or more wheels of the base assembly and thus frictionally engages the floor surface and prevents movement of the machine on the base assembly. Turning the drive member in the opposite direction allows the stop member to be retracted up into the housing assembly. In this unlocked position, the weight of the machine is borne by wheels that allow the machine to be rolled from one location to another.

The computer further includes a device application portion (84) which interfaces with the HTML document handling portion and dispatches messages to operate devices (36) in the automated banking machine. The devices include a sheet dispenser mechanism (42) which dispenses currency as well as other transaction devices. The device application portion communicates with a device interfacing software portion (64) in the banking machine through a device server (92) in the intranet. The device server maintains local control over the devices in the banking machine including the sheet dispenser. The banking machine operates to read indicia on the user's card corresponding to a system address. The computer is operative to connect the banking machine to the home or foreign server corresponding to the system address, which connected server operates the banking machine until the completion of transactions by the user.

IPC: F16F15/26
Filed: 2000-08-17
Granted: 2004-10-05
Abstract: In a balance shaft for engine balancing systems for canceling an unbalance force of an engine, a journal portion of the balance shaft is provided with a recess on a side remote from the gravitational center of the counter weight, and a rib extends axially across this recess along a radial plane between fu ll circular axial end portions of the journal portion to compensate for the reduction in the bending rigidity of the balance shaft due to the provision of the recess. The recess reduces the weight or mass of the balance shaft, and this recess does not diminish the performance of the bearing because the bearing load is essentially due to the unbalanced mass of the counter weight portion, and the recessed part of the bearing portion receives a significantly smaller part of the bearing load than the opposite side of the bearing portion. The recessing also contribute s to increasing the eccentricity of the gravitational center of the associated part.

Abstract: An apparatus and a method are disclosed for manufacturing an integral one--piece catheter having a tube and a hub. The method comprises feeding molten material into a mold having a mold cavity. A fluid such as a gas is injected into an inlet of the mold. This causes the cavity to eject the molten central region of the polymer through an exit channel. In one embodiment, a gas is injected into the hub portion of the cavity. In another embodiment, a gas is injected into the catheter portion of the mold. The invention also involves forming a first portion of an intravascular device using a first material in a first mold. Thereafter the first portion of the intravascular device is inserted into a second mold to form a second portion using a second material. Gas is then introduced to form a hollow channel in the second portion. The invention also involves a first portion of the mold is injected with a first material, and a second portion of the cavity is injected with a second material at or around the same time that the first material is injected into the first portion of the cavity.
