Patent CA-2164632-A1 (CA)
Title: Treatment of vascular degenerative diseases by modulation of endogenous nitric oxide production or activity
Inventor: COOKE JOHN P
IPC: A61K31/195
Filed: 1994-06-02
Abstract: Atherogenesis and restenosis are treated by long term administration of physiologically acceptable compounds which enhance the level of endogenous nitric oxide or other intermediates in the NO inducted relaxation pathway in the host. Alternatively, or in combination, other compounds may be administered which provide for short term enhancement of nitric oxide, either directly or by physiological processes. In addition, cells may be genetically engineered to provide a component in the synthetic pathway to nitric oxide, so as drive the process to enhance nitric oxide concentration, particularly in conjunction with the administration of a nitric oxide precursor.

Title: Lock for a Safe-Deposit Box
Inventor: YEN CHIEH-CHENG
IPC: E05B63/00
Filed: 1996-01-19
Abstract: A safe-deposit box uses a lock including a tongue, a first mechanical device, a second mechanical device, a solenoid, a control unit and a keypad.  A renter's key drives the first mechanical device from a first position to a second position to actuate the control unit.  The solenoid is in a first position to retain the first mechanical device in the second position.  A code is input through the keypad to the control unit to drive the solenoid from the first position to a second position to allow movement of the mechanical device from the second position to a third position to retract the tongue.  A clerk's key can drive the second mechanical device from a first position to a second position to drive the solenoid from the first position to the second position and turn off the control unit.  If the code is forgotten, the second mechanical device is driven from the second position back to the first position to retain the solenoid in the second position to allow movement of the first mechanical device from the first position to the third position.  If the renter fails to pay rent for the safe, the second mechanical device is driven from the second position through the first position to a third position to drive the solenoid back to the first position to prevent movement of the first mechanical device from the first position to the third position.

Title: Treatments to reduce frictional wear between components made of ultra-high molecular weight polyethylene and metal alloys
Inventor: DEARNALEY GEOFFREY
IPC: A61F2/00
Filed: 1995-03-22
Abstract: The present invention provides methods for modifying surfaces of metal alloy and/or UHMWPE (ultra-high molecular weight polyethylene), preferably surfaces which are frictionally engaged, e.g., in an orthopaedic implant. The methods reduce the coefficient of friction of the metal alloy component, reduce the shearing of fibrils from the UHMWPE component. One method involves solvent immersion of the UHMWPE component to remove short chains of polyethylene at or near its surface, and to swell and toughen its subsurface.  Another method also involves firmly coating the surface of the metal alloy component with an adherent layer of diamond-like carbon ("DLC") by creating a metal-silicide interface at the surface of the metal alloy to permit firmer adhesion of DLC. Although these methods are particularly useful in orthopaedic applications, they can also be used to treat similar components used in other applications.

Abstract: A recombinant DNA containing a sequence (1) coding for a polypeptide heterologous to a filamentous haemagglutinin of Bordetella (Fha) fused within the same reading frame to a sequence (2) located upstream from the first sequence. Said sequence (2) codes for at least a part of the Fha precursor, which part comprises at least the N-terminal region of a truncated mature Fha protein which contains the interaction site of Fha and heparin, and which, when it is itself subjected on its own to the control of a promoter recognised by the cell polymerases of B. Pertussis, and inserted into a B. Pertussis cell culture, is expressed in said culture under the control of said promoter and excreted into the cell culture medium. The invention uses both the abilities of Bordetella, and particularly B. Pertussis, which does not appear to produce extracellular proteases, and the ease with which filamentous haemagglutinins can be isolated from those of the Bordetella synthesising same.
