Patent CA-2190253-A1 (CA)
Title: Device and methods for in vivo culturing of diverse tissue cells
Inventor: RINGEISEN TIMOTHY
IPC: C12N5/077
Filed: 1995-05-15
Abstract: An anatomically specific, bioresorbable, implant device for facili-tating the healing of voids in bone, cartilage and soft tissue is disclosed. A preferred embodiment of using the implant device for facilitating the healing of a human joint lesion includes a cartilage region invested with an alginate microstructure joined with a subchondral bone region in-vested with a hyaluronan microstructure. The alginate selectively dis-persed in the cartilage region enhances the environment for chondrocytes to grow articular cartilage. The hyaluronan selectively dispersed in the subchondral bone region enhances the environment for mesenchymal cells which migrate into that region's macrostucture and which differ-entiate into osteoblasts. The microstructures can be invested at varying concentrations in the regions. A hydrophobic barrier, strategically po-sitioned within the subchondral bone region macrostructure, shields the chondrocytes from the oxygenated blood in subchondral cancellous bone. In the preferred form, the cartilage region includes a tangential zone in-cluding a network of intercommunicating void spaces having a horizontal orientation and in communication with synovial fluid and includes a ra-dial zone including multiple void spaces oriented in both horizontal and vertical planes and providing intercommunication between the tangential zone and the subchondral bone region.

Title: Device and method to stabilize sheet between press section and dryer section of a paper-making machine
IPC: D21G9/00
Filed: 1996-11-18
Abstract: A novel sheet transfer stabilizer is provided for transferring a fibrous wet sheet from a press section to a dryer section of a paper-making machine by way of a felt or fabric. The sheet transfer stabilizer includes a composite Venturi box which is disposed between a felt or fabric roll of the press section and a first dryer. The Venturi box includes three side-by-side Venturis, namely an inlet Venturi, an outlet Venturi, and a main Venturi. Such Venturi boxes are used to create and maintain a vacuum in the felt or fabric web system. In addition, a novel method is provided for guiding a wet fibrous web from a press section to a drying section of a paper-making machine. The method includes the steps of passing the wet fibrous web from the press section in an open draw onto a felt or fabric, the felt or fabric passing about a guide roll. The wet fibrous web and the felt or fabric, are urged against each other as a drying wire of the drying section passes from the guide roll to a drying cylinder by the generation of negative pressure in the space on the side of the felt or fabric, which is opposite to the side of the felt or fabric, which supports the fibrous web. The negative pressure is generated using the combination of an inlet Venturi, having an inlet opening and a throat, the inlet Venturi being located adjacent to the guide roll in order to draw up and exhaust air from an area where the paper web separates from the surface of the guide roll, or an outlet Venturi having an inlet opening and a throat, the outlet Venturi being situated adjacent to the drying cylinder to draw away air from a gap between the dryer cylinder and the inlet opening of the outlet Venturi; or a main Venturi having a first and second inlet openings and throat, the main Venturi being disposed between the inlet Venturi and the outlet Venturi to draw away air away from, and to maintain a negative static pressure over, an unsupported span between the guide roll and the dryer cylinder.

Abstract: An end fitting for use in a vehicular drive shaft assembly includes a body having a cylindrical sleeve portion extending therefrom. The sleeve portion of the end fitting has a plurality of recessed areas formed therein which extend longitudinally from a first end of the sleeve portion to a second end thereof.  The recessed areas may be defined by planar surfaces which intersect the sleeve portion of the end fitting at a slight angle relative to the axis of rotation thereof. Each of the recessed areas has a cross sectional shape defined by a radial depth and a chordal width. The cross sectional shapes of the recessed areas vary along the lengths thereof. Preferably, the radial depths and the chordal widths are at minimum values adjacent the first end of the sleeve portion of the end fitting and are at maximum values adjacent the second end of the sleeve portion. To assemble the drive shaft assembly, adhesive is applied either to the outer chordal surface of the sleeve or to the inner cylindrical surface of a drive shaft tube. Then, the sleeve portion of the end fitting is inserted within the drive shaft tube such that the outer surface of the sleeve portion engages the inner cylindrical surface of the drive shaft tube in a light press relationship. As the leading edge of the end fitting is inserted within the drive shaft tube, the adhesive is urged to flow into the recessed areas. The adhesive material is subsequently cured to form an adhesive bond between the end fitting and the inner cylindrical surface of the drive shaft tube.

IPC: B62D65/00

Abstract: A procedure for the construction, making and remaking of road vehicles in accordance with the invention makes it possible to increase the width of road vehicles, in particular standard-make road vehicles. The procedure in accordance with the invention is based on an asymmetrical extension whereby all vital parts of the driver's surroundings (steering, control assemblies and the parts of the driver's position) are kept unchanged, and need not be altered or remade. In this way the design, making and remaking are facilitated and an extension of the useful space is obtained. The procedure for the construction, making and remaking of extended road vehicles in accordance with the invention consists in keeping the vital assemblies (the driving and control assemblies) and the driver's working surroundings in their original dimensions and installation, while carrying out the extension by introducing, symmetrically or asymmetrically, or by a combination of both, an inset into the longitudinally extended vehicle. Such a construction, making and remaking keeps, essentially, all the vital parts of the original road vehicle (the control and driving parts remain unchanged). The steering wheel, the driver's surroundings with the seat and the distance between the wheels or the clamping of the front wheel remain, in any case, in the same relationship as in a series-produced, non-extended vehicle, regardless of the right- or left-hand installation of the steering wheel, or of the right- or left-hand installation of the engine.

Title: Procedure for detoxification of shellfish, contaminated with paralytic shellfish toxins
Inventor: HINRICHSEN JUAN PABLO
IPC: A23L17/50
Filed: 1997-08-06
Abstract: This invention relates to a process for detoxifying shellfish contaminated with paralytic toxin. Decontamination is achieved through a process involving the chemical treatment of shellfish. This chemical treatment consists of cooking theshellfish in an alkaline pH solution. This treatment can be combined with one or more other procedures for the reduction of the products' final toxicity, these other procedures including, for example, partial shellfish detoxification by depuration, removal of the most toxic parts, and commercial cooking/canning of the shellfish. The process reduces total toxicity levels in shellfish to values below 80 ug of eq. STX/100 g of shellfish, independently of the toxin profile, or of the initial toxicity present in the shellfish.
