Patent CA-2187747-A1 (CA)
Title: Tooling using thermostructural composite materials containing carbon for heat treatment and/or thermochemical treatment installations
Inventor: MAUMUS JEAN-PIERRE
IPC: B22D19/14
Filed: 1996-03-08
Abstract: An interposition layer (12) is formed on the outside surface of a part (10) made of thermostructural composite material containing carbon, and a metal case is formed by casting molten metal (22) around the part provided with its interposition layer. The interposition layer has closed porosity and it is proof against the metal of the case, such that shrinkage of the metal during cooling is absorbed by compacting or collapsing the porosity of the interposition layer, thereby preserving the integrity of the metal case, and the interposition layer constitutes a diffusion barrier preventing eutetics forming by contact between the metal of the case and the composite material.
Patent CA-2189463-A1 (CA)
Title: Self-Expanding Stent
Inventor: CARPENTER KENNETH W
IPC: A61F2/82
Filed: 1996-11-01
Abstract: The present invention provides a self-expanding stent for insertion into an artery or other internal vessel. The stent is formed from a series of radial bands each formed with overlapping first and second ends. The overlap between the first and second ends is variable, allowing each band to move between a contracted configuration and an expanded configuration. The first and second ends of each band are both formed to include a tab which is folded to hold the first and second end against the band.  The bands are distributed along a common axis to form a cylinder and interconnected by a pair of elongated strips. In use, the stent is placed over a balloon catheter and compressed to adopt the contracted configuration. The balloon catheter and stent are then advanced through a placement catheter and  to  a  target  site  where  the  balloon  is  partially inflated to free the stent for self-expansion. The balloon may then be more fully inflated to further expand any of the radial bands in the stent. The balloon is then deflated and removed,  leaving the expanded stent to support that target site.

Title: Phase linear class e amplifier for a satellite communication system
Inventor: SEVIC JOHN F
IPC: H04B7/155
Filed: 1995-05-10
Abstract: A low earth orbiting satellite communication terminal includes a data signal generator, a modulator, and a class E switching amplifier. The modulator converts a data signal from the data signal generator into a phase modulated signal which is then amplified by the class E switching amplifier for transmission to a low earth orbiting satellite. In a preferred embodiment, the modulator converts the data signal into a symmetric differential phase shift keyed data signal. The class E switching amplifier amplifies the phase modulated signal at frequencies between about 148 and 150 MHz. The class E switching amplifier includes a switching transistor, an input matching network, a class E load network, and an output matching network. The class E load network is electrically connected to the switching transistor and loads the transistor for phase linear class E operation over a predetermined bandwidth. The class E switching amplifier may include a transistor which is designed to operate at a first predetermined frequency and at a first predetermined voltage, but which is preferably operated below these predetermined levels.

Filed: 1995-06-07
Abstract: A core for core wound paper products. The core is made by wrapping dual plies (22, 24) in a spiral pattern and adhering the plies together. The edge (34) of one ply (24) overlaps the ply gap (36) of the other ply (22), preventing a single ply thickness from occurring anywhere on the core. Alternatively, the edge (34) of each ply may overlap the ply of that respective ply. In yet another embodiment, the overlap (42) may be formed by a separate ply applied to either ply.

Title: Self-adhering walkway pads for roofing membranes and method for the application thereof to roofs
Inventor: RUSSELL DONALD R
IPC: C09J7/10
Filed: 1997-02-14
Abstract: A self-adhering walkway pad (20) comprises an elastomeric pad having upper and lower surfaces (21, 22) and a 100 percent solids tape (25) pre- applied to the lower surface of the pad, prior to use in the field.

Inventor: LUI HARVEY
IPC: A61N5/06
Filed: 1997-05-27
Abstract: Porphyrins, particularly protoporphyrin IX, are elevated in psoriatic plaques as compared to normal skin and skin of patients with other dermatological diseases. Psoriatic plaques with elevated porphyrin levels may be detected by fluorescence and spectral analysis. Endogenous porphyrins in psoriatic plaques may be activated with visible light to treat psoriatic plaques having elevated porphyrin concentrations. Skin conditions may be optimized to increase the endogenous synthesis of porphyrins in psoriatic plaques. A topical formulation may be applied to psoriatic plaques to optimize skin conditions such as pH, iron concentration, temperature, hydration, calcium concentration, oxygenation, electrical conductivity and estrogen concentration for increased production of endogenous porphyrins.

Abstract: On utilise des dérivés d'acide gras de composés contenant du sulfhydryle (par exemple, des peptides ou des protéines contenant du sulfhydryle), notamment des produits d'acide gras conjugués avec une liaison de bisulfure, pour administrer lesdits composés à des cellules de mammifères. Cette modification permet d'augmenter consdérablement l'absorption des composés par les cellules de mammifères en ce qui concerne le taux d'absorption des composés non conjugués, de même qu'elle prolonge la rétention des composés dans le sang et les tissus. En outre, la liaison de bisulfure dans le conjugué est assez labile dans les cellules, ce qui facilite la libération intracellulaires des composés intacts par les fractions d'acide gras.
