Title: An adhesive-free lens-attached optical fibers to optical waveguide packaging system
Inventor: BENHAM VICTOR
IPC: G02B6/30
Filed: 1999-01-07
Abstract: To make a low loss connection between the cores of lens-attached fibers (13) and an optical waveguide (8) imprinted on a waveguide substrate (6), the combination of two protective gaskets (1) and (2), and supporting plates (14) is firmly pressed against the waveguide substrate (6). Grooves (5) are arrangers to align the lens-attached fibers with respect to the waveguide. The grooves are formed by the application of an associated etching procedure described in literature. The lens (7) is built by dipping the end-face of the fibers into a transparent adhesive such as sol-gel solutions followed by curing with an associated annealing process. The lens-attached ends of the fibers, which are placed in a pre-determined distance with respect to the optical waveguide, are protected by two gaskets (2) and (1), positioned below and above the fibers. The adhesive free system enables a repeatable and reproducible translational alignment and is independent of the nature of the optical waveguide. The disclosed packaging method also achieves a precise vertical alignment of fiber core and waveguide. The whole assembly is held together and packaged by the tightening force of two outer most plates (17) and (22). Finally, the inexpensive packaging method can be assembled and disassembled for repeated use, as many times as necessary.

Title: Reactive melt adhesive composition for double glazing
Inventor: GRIMM STEFAN
IPC: C09J119/00
Filed: 1997-06-09
Abstract: Melt adhesive compositions containing a mixture of at least one reactive binder based on silane-functional polyisobutylene, hydrated polybutadiene and/or poly-.alpha.-olefines and a non-reactive binder from the group of butyl rubbers, poly-.alpha.-olefines and a non-reactive binder from the group of butyl rubbers, poly-.alpha.-olefines, polybutenes, styrene block copolymers or diene polymers may be used as one or two-part adhesives/sealants for the production of double glazing. Here, no separate spacer of metal or plastic sections are needed. As the entire edge bond consists of a uniform material, on the one hand the production process for the double-glazing units can be greatly simplifed and on the other the uniform material can be subjected particularly easily to a recycling process after a double-glazing unit has been dismantled, as it not a composite material.

Patent CA-2262854-A1 (CA)
Inventor: SCHMIDT MARTIN A
IPC: F01D25/20
Filed: 1997-07-14
Abstract: The invention provides a micro-gas turbine engine and associated microcomponentry. The engine components, including, e.g., a compressor, a diffuser having diffuser vanes, a combustion chamber, turbine guide vanes, and a turbine are each manufactured by, e.g., microfabrication techniques, of a structural material that can be common to all of the elements, e.g., a microelectronic material such as silicon or silicon carbide. Vapor deposition techniques, as well as bulk wafer etching techniques, can be employed to produce the engine. The engine includes a rotor having a shaft with a substantially untapered compressor disk on a first end, defining a centrifugal compressor, and a substantially untapered turbine disk on the opposite end, defining a radial inflow turbine. The rotor is preferably formed of a material characterized by a strength-to-density ratio that enables a rotor speed of at least about 500,000 rotations per minute. An annular, axial-flow combustion chamber is provided that is located axially between the compressor and turbine disks and that has a ratio of annular height to axial length of at least about 0.5. The micro-gas turbine engine can be configured with an integral microgenerator as a source of electrical power, and can be employed for a wide range of power, propulsion, and thermodynamic cycle applications.
Patent CA-2262898-A1 (CA)
Title: Screw rotor set
Inventor: BECHER ULRICH
IPC: F04C2/16
Filed: 1997-07-21
Abstract: Known designs of single-thread screw rotors in single-piece cast iron constructions having wrap angles of > 720 degrees with balancing cavities on the face of the screw operate with no unbalance at average rotary frequencies of (~ 3000 min-1). The use of a pump in processes having sensitive purity and maintenance requirements or working with corrosive substances or where limited space is available and quality is demanded, brings about problems for rotor designing and balancing, which the present invention solves. An uneven mass distribution is accomplished by constructing the rotors with several single parts inside the rotor, by forming cavities and/or by choosing the adequate material, which, combined with the screw length/pitch ratio, cause a static and dynamic balancing. Screw rotors designed as described offer several advantages since they are easy to assemble and have a compact and stable construction.  Moreover, they can be used in pumps for the food industry, chemistry, medicine and semi--conductor construction due to the flexibility in material and to the smooth surfaces free from cavities.

Patent CA-2267542-A1 (CA)
Title: Processing image data
Inventor: WEAVER DALE MATTHEW
IPC: G11B27/034
Filed: 1999-03-30
Abstract: Audio data and visual data are processed by providing storage devices (211, 212) for storing digital samples which are then read in response to edit events defined by a timeline (352, 353). Active audio tracks are processed in real time and an event, such as a cross-fade, defined by a single track that requires two interacting tracks of material, is identified. The location of events within available tracks is re-arranged so as to reduce the total number of active tracks required during playback. In effect, events are transferred to blank regions of existing tracks, thereby allowing both of the interacting tracks of cross-fades to be read without requiring additional track capacity during playback. In this way, an event defined by two interacting tracks is processed without requiring additional processing capacity.

Title: Improved detection of mutations in nucleic acids by chemical cleavage
Inventor: BLOCH WILL
IPC: C12Q1/68
Filed: 1998-08-06
Abstract: Improved methods, compositions and kits for detecting mutations in nucleic acids are disclosed, such comprise annealing a piece of control nucleic acid without mutations to a piece of test nucleic acid very similar in sequence to the control nucleic acid but possibly containing mutations, treating this mixture with potassium permanganate or hydroxylamine to remove mismatched bases from the duplex nucleic acid, treating the resulting nucleic acid with any of a class of diamines, triamines, and tetraamines analogous to 1,2ethylenediamine to cleave abasic sites, and then analyzing the chemically treated nucleic acid to determine whether cleavage has occurred and approximately at what position in the nucleic acid any cleavage has occurred. Inclusion of betaine in the base-removal reactions improves their sensitivity and specificity. This series of non-hazardous, non-noxious, chemical treatments can be performed rapidly in a single reaction tube with no or minimal intervening separation steps; and the cleavage product can be prepared for the analysis step without removing the chemical reagents used to effect cleavage.
