Title: Mid-roof anchoring system
Inventor: BELLEM NORMAN A
IPC: E04D3/36
Filed: 1994-03-30
Granted: 1998-09-29
Abstract: A mid-roof anchoring system includes a series of anchoring channels secured to the roof structure along a line midway between the eave and the ridge of the roof.  Metal roof panels installed over the substructure are permitted to float laterally on the roof, except where they are attached to the anchoring channels.  As a result, the roof panels expand or contract in both directions away from the midway line.  This approach minimizes thermally induced movement the upper and lower edges of the roof, and minimizes reaction forces at the anchor.

Title: Surgical prosthetic implant for vertebrae
Inventor: BRANTIGAN JOHN W
IPC: A61F2/00
Filed: 1992-09-04
Granted: 2003-06-17
Abstract: Surgical prosthetic modular implants (10, 20, 30, 40) used singularly or stacket together are provided to support and fuse together adjacent verte-brae or to totally or partially replace one or more vertebrae in a vertebral co-lumn. The implants are rigid annular plugs (11, 21, 31, 41), dimensionally si-milar to normal vertebral bodies, have simplified oval or semi-oval shapes with ridged faces (12, 16, 22, 42) to engage adjacent vertebral bodies to resist displacement and allow bone ingrowth and fusion and to interdigitate with the ridges of an adjacent plug for modular stacking to allow variability of ul-timate implant height. The implants can be provided in sets of different thicknesses and are internally grooved (24) to receive an upstanding con-necting bar (15) to bind together the individual stacked implants into a stable unit (17, 25, 44). The annular implants have ample spaces (11d, 11e, 211) to allow blood flow and packing of bone graft and are preferably made of a radiolucent material, preferably biocompatible carbon fiber reinforced polymers or are alternately made of traditional or thopaedic implant materi-als such as nickel, chromium, cobalt, stainless steel or titanium.

Title: Modulateur optique a bande passante electro-optique a variations graduelles
Inventor: FARINA JAMES D
IPC: G02F1/225
Filed: 1992-12-04
Granted: 1999-04-06
Abstract: Un modulateur d'intensité optique comprend un substrat (10) d'un matériau optique conducteur de la lumière et des ondes acoustiques, et possède à la fois des propriétés électro-optiques et piézoélectriques. Le modulateur optique se compose généralement d'un interféromètre Mach-Zender comprenant une paire de guides d'ondes lumineux, allongés, combinés (11, 12) formés dans le substrat, ces guides d'ondes s'étendant pratiquement sur une même étendue les uns par rapport aux autres, et se trouvant séparés les uns des autres d'une distance transversale qui varie graduellement le long de leurs déplacements. Des décalages de phase différents sont induits en imposant des champs électriques variables sur chacun des guides d'ondes au moyen d'électrodes (21, 22, 23). Du fait de l'écartement variable des guides d'ondes le long de leurs déplacements, la tendance des ondes acoustiques, générées lors du fonctionnement du modulateur par l'effet piézoélectrique, à résonner entre les guides d'ondes à certaines fréquences, est éliminée, réduisaant ainsi la distorsion de bruit correspondante.

Title: Limiting orifice drying of cellulosic fibrous structures, apparatus therefor, and cellulosic fibrous structures produced thereby
Inventor: ENSIGN DONALD EUGENE
IPC: B32B7/00
Filed: 1993-06-10
Granted: 1998-10-13
Abstract: A method and apparatus for drying of a cellulosic fibrous structure having const ant basis weight and/or density or multiple regions varying in basis weight and/or density. Such a cellulosic fibrous struct ure may have a nonuniform moisture distribution prior to drying by the disclosed method and apparatus. An equally or more unifor m moisture distribution is achieved by providing a micropore medium in the air flow path which has a greater flow resistance than the interstices between the fibers in the cellulosic fibrous structure web. The micropore medium is the limiting orifice i n the air flow used in the drying process. The micropore medium may be executed in a laminate of plural laminae, each of succes sively increasing or decreasing pore size. This arrangement provides the advantage that minimal sagging or deformation of each l amina into the next coarser lamina occurs and lateral air flow between the micropore medium and the cellulosic fibrous structu re is reduced. The micropore medium may be disposed either upstream or downstream in the air flow path of the cellulosic fi brous structure to be through-air dried.

Abstract: An apparatus for bending heat-exchanger tubes, which heat-exchanger tubes have heat-exchanger ribs, preferably having a needle construction. In the apparatus, the heat-exchanger tubes are placed one above the other to form a battery. The battery of heat-exchanger tubes is fed first into a first bending-device portion of the bending device, in which the heat-exchanger tubes are bent in one direction. After this, the tube battery is fed further, and bending is performed in the second bending-device portion in the opposite direction of bending, whereby a wave-shaped form is obtained.

Granted: 2000-08-15
Abstract: The useful life of electrical contacts is extended by a cryogenic treatment.  An electrical contact is exposed to a low temperature, such as below 172 K for a selected period of time.  The low temperature may be obtained via a controlled rate of cooling.  After the contact has been exposed to the low temperature, the contact may be returned to ambient temperature at a controlled rate.  The cryogenic treatment results in extended useful life of contacts made of materials such as copper and of composite contacts incorporating silver, refractory metals, and metal oxides such as cadmium oxide and tin oxide.

Patent CA-2156081-C (CA)
Inventor: DEAKIN MARTIN JOHN
IPC: C23C14/16
Filed: 1994-02-15
Granted: 2004-07-27
Abstract: A method of applying a continuous stable intermetallic diffusion barrier layer to a high temperature metallic article is described. In many instances, protective coatings are incompatible with the material of the substrate to which they are applied. Such incompatilibility is overcome in the invention through in situ formation of an intermediate stable diffusion barrier layer by sequential deposition and subsequent reaction of suitable metals to form a continuous intermetallic layer. A  conventional overlay coating may then be applied to the intermetallic layer without risk to the underlying substrate. The invention also contemplates creation of unitary diffusion barriers from multi-layer deposits; deposition of plural diffusion barriers, and formation of complete protective systems comprising substrate, diffusion barrier(s) and overlay coating prior to heat treatment in situ.

Title: Center readout intra-oral image sensor
Inventor: SAYAG MICHEL
IPC: H04N5/32
Filed: 1995-12-18
Granted: 1999-09-21
Abstract: A solid state image sensor CCD array (10a) has a two block, full-frame, parallel-register structure. The two blocks of the array, each comprised of photosensitive radiation sensors or pixels (20), feed into a single centrally disposed serial read-out register (10b) so as to form one unified photosensitive domain. The read-out register is photosensitive except for two associated narrow clock buses (H1, H2) that are spaced apart so as to only block a minimum of input radiation in any one pixel (22) of the read-out register. Each stage of the read-out register can act as a pixel that is approximately square and that is approximately the same size as the pixels of the two full- frame blocks. In operation, the centrally disposed read-out register can be stationary for a significant first portion of a total frame time (integration period), and then in a latter part of the frame time it can be read out one or more times to provide exposure update information for all of the pixels of the array. Typical examples of applications include advanced histogram-based, or other types of, X-ray exposure optimization. The array avoids the use of an "amplifier corner" that is characteristic of most if not all area image sensors. As such, all four corners of the array can be shaped to suit a particular application. One application of particular interest is for intra-oral dental X-ray imager and system.
