Patent CA-2281690-A1 (CA)
Title: Method for destroying retinal pigment epithelial cells
Inventor: BRETTON RANDOLPH H
IPC: A61K31/715
Filed: 1998-01-28
Abstract: A method for destroying retinal pigment epithelial cells in an eye in order to prevent the occurence of proliferative vitreoretinopathy. A solution containing a basement membrane binding agent conjugated to a cytotoxic agent is introduced into the vitreous chamber. The solution is maintained in the vitreous chamber for a period of time sufficient to permit the basement membrane binding agent to bind to basement membranes lining the vitreous chamber. The solution is then removed from the vitreous chamber, whereby a portion of the basement membrane binding agent remains bonded to basement membranes within the vitreous chamber, thereby exposing retinal pigment epithelial cells disposed on the basement membrane to the cytotoxic agent.

Title: Flexible, low density thermoplastic foams and methods for lowering the density and increasing the flexibility of thermoplastic foams
Inventor: WEIBEL JUERG PATRIK
IPC: C08J9/36
Filed: 2000-04-27
Abstract: A flexible, low density thermoplastic foam and a method for lowering the density and increasing the flexibility of a thermoplastic foam having a melting temperature and being either amorphous with a softening temperature or semicrystalline with a glass transition temperature. The method comprises the steps of (a) decreasing the pressure on the thermoplastic foam to a subatmospheric pressure, further providing that while the thermoplastic foam is under the subatmospheric pressure, the thermoplastic foam is also at a temperature in the range of less than the melting temperature and greater than the softening temperature if the thermoplastic foam is amorphous, or greater than the glass transition temperature if the thermoplastic foam is semicrystalline, whereby the thermoplastic foam expands;  (b) then exposing the thermoplastic foam to a superatmospheric pressure and a secondary expansion gas for a sufficient amount of time to allow the secondary blowing gas to permeate into the thermoplastic foam; and (c) then releasing the superatmospheric pressure on the thermoplastic foam whereby the thermoplastic foam expands.  With this method, it is possible to produce thermoplastic foams having densities as low as 0.008 grams/cc. Also included in this invention are insulations made from these low density foams.

Title: Silicon based conductive material and process for production thereof
Inventor: SADATOMI NOBUHIRO
IPC: H01B1/04
Filed: 1998-08-14
Abstract: A silicon based conductive material based on a semiconductor silicon and having an electric resistivity of 10 -3 (.OMEGA. . m) or less at ambient temperature, which has been unattainable heretofore, while facilitating production and handling. An electric resistivity of -6 (.OMEGA. . m) or less, which is common for conductors, can be realized by adding relatively large quantities of various kinds of elements to silicon. The conductive material can be provided in a semiconductor silicon substrate in a desired pattern by ion beam implantation and patterning.

IPC: D06F37/22
Filed: 1997-01-29
Abstract: A drum washer-drier which includes a drum rotating about a horizontal rotary axis, a water tank including a drum, and an outer tank resiliently supporting the water tank. A plurality of suspending rods are suspended from an upper inner surface of the outer tank, and the water tank is resiliently supported by providing compression springs between spring-receiving portions at lower ends of suspending rods and support-receiving portions of the water tank. Further, a damper generating a sliding resistance as the spring is expanded/compressed is provided at the lower end portion of each suspending rod. At the time of dehydration, the drum is rotated for a prescribed time period at a rotation speed higher than a critical rotation speed of a fluid balancer, but lower than a resonance rotation speed caused by resilient support, and thereafter high-speed rotation starts. A structure for protecting the fluid balancer formed of synthetic resin during drying is also disclosed.

Inventor: DE ANGELIS CLAUDIO
IPC: D07B1/22
Filed: 2000-06-09
Abstract: A synthetic fiber rope to be driven by a rope sheave is constructed as a twin rope (30) consisting of two ropes (14), (15) with opposite directions of twist (S), (Z) which are laid together and fixed in their positions parallel to, and at a distance from, each other, and so as not to rotate, by means of a common rope sheath (17). The rope sheath (17), which according to the invention is constructed over both ropes (14), (15), acts as a torque neutralizer which, when the twin rope (3) is loaded longitudinally, mutually offsets the oppositely oriented torques of the ropes (14), (15) which arise due to the structure of the rope, thereby causing over the entire cross-section of the twin rope (3) equalization of the torques from the sum of all the parts having right-hand strands and all the parts having left-hand strands. When the twin rope (3) runs over a rope sheave its behavior is free of rotation.

Title: Low friction doctor blade
Inventor: BUCHANAN JOHN ANDREW
IPC: G03G15/08
Filed: 2000-09-21
Abstract: A device within an image forming apparatus for positioning a doctor blade against a developer roller and preventing toner leakage. The device includes a developer housing for containing the developer roller and the doctor blade. A biasing member is positioned adjacent to the doctor blade for forcing the doctor blade against the developer roller for controlling the mass flow and charge level of the toner. The doctor blade is supported by retention stops on a front edge and a pair of supports on the back edge. Toner is prevented from leaking through the device by a flap seal positioned along the doctor blade back side and a seal positioned between each end of doctor blade end and developer housing. The invention provides for the doctor blade to be freely positioned between the retention stops, developer housing, and seals providing for the doctor blade to contact the developer roller in a consistent manner.
Patent CA-2320461-A1 (CA)
Inventor: RADEMACHER JOHN J
IPC: F04C27/00
Filed: 2000-09-22
Abstract: A light-weight vacuum pump has a multi-wiper member circular wiper member support and impeller which is eccentrically mounted within a pump housing. The multi wiper member circular support carries from about five to nine wiper members each mounted within a slot extending substantially the length of the support, with each wiper member being centrifically urged outwardly to wipingly engage an inner surface of a round or elliptical walled pump housing. Eccentric action enables the wiper members to be extended to create a large space between adjacent wiper members as an inlet is passed. As the wiper members pass by the inlet, the acentric cylindrical wall of the pump housing begins to compress the wiper members into the support, thereby reducing the space between adjacent wiper members in a compressive manner. The wiper member support further carries an added volume pocket between adjacent pairs of wiper members in order to (1) take in more air volume, and (2) create a less severe compression per inter wiper member volume compressed. This configuration can deliver high volumes of evacuated dump air and yet create significantly high vacuum at higher speeds of operation.

Title: Vecteurs heteroduplex mutationnels et leur utilisation dans les bacteries

Filed: 1999-05-12
Abstract: L'invention concerne la découverte du rôle actif des oligonucléobases de recombinaison dans les cellules eucaryotes qui présentent une activité de transfert de brin (RecA) et une activité de réparation de mésappariement (MutS). Sur la base d'un tel système, on a montré qu'un vecteur duplex mutationnel appelé vecteur hétéroduplex mutationnel était plus actif dans les cellules procaryotes que les types de vecteurs mutationnels testés jusqu'à présent. On a encore amélioré l'activité en remplaçant le segment de liaison tétrathymidine par un oligonucléotide résistant à la nucléase, du type tétra-2'-O-méthyl-uridine, de manière à lier les deux brins de l'oligonucléobase de recombinaison. Une autre amélioration a consisté à éliminer le segment intervenant qui contient de l'ADN. L'invention concerne donc des vecteurs hétéroduplex mutationnels présentant les améliorations décrites. Selon un aspect, l'invention concerne l'utilisation desdits vecteurs dans les cellules procaryotes.
