Inventor: KOCHS KARL-JOSEF
IPC: A41H37/10
Filed: 1994-09-06
Abstract: The invention pertains to a ma-chine for attaching buttons, rivets or the like, preferably to clothing, said buttons, rivets or the like consisting of an upper part and an under part, wherein material held between upper and lower clamp-ing jaws is perforated by means of a ram stroke and wherein a carriage hav-ing an upper tool and a lower tool is displaced through convergence of upper and lower tools and the button parts car-ried therein are joined in an interlock-ing fit by means of a ram stroke. To perform the necessary perforation of the garment prior to attachment of the arti-cle, using the same machine and without changing the position of the garment, the invention provides that a ram-end attachment tool (36) is situated in hole-punching position coaxially to a hole-punching tool (26).

Inventor: WASHIZAWA TERUYOSHI
IPC: H04N19/94
Filed: 1996-03-29
Abstract: A transformation unit 102 transforms an entered image to multi-resolution space.  A quantizer 105 performs vector quantization on a local pattern of an image of a multi-resolution representation.  A perspective-order calculating unit 107 extracts a plurality of code words, positions corresponding thereto and/or angle of rotation and/or scale, and the perspective-order relationship of a plurality of these representative vectors, from the quantized image.  An algebraic encoder 108 encodes the input image based upon the extracted information. As a result, there are provided an image processing apparatus and method for asymmetric encoding without motion in three dimensions and extraction of a three-dimensional structure.  Further, a transformation unit 1103 transforms an entered image to vector field, and a singularity detector 1104 detects a singularity in the transformed image.  A transformation encoder 1105 partitions the vector field into areas which include detected feature points, and each area is encoded by functional approximation.  As a result, a finite number of feature points can be obtained with ease and an image processing apparatus and method exhibiting strong resistance to the effects of noise are provided.

Title: Blood chamber
Inventor: UTTERBERG DAVID S
IPC: A61M1/36
Filed: 1996-05-10
Abstract: A plastic blood chamber comprises a chamber-defining wall having a first blood inlet port adjacent to the end of the chamber and a blood outlet port adjacent typically the opposed end of the chamber. The inlet port is positioned in separate, lateral relation with the chamber, and has a conduit extending longitudinally of the chamber from the inlet port toward a central chamber portion in such separate, lateral relation to the chamber. The conduit curves into communication with the chamber in a transverse direction at an inlet position in the central chamber portion. A second portion of the chamber which is laterally opposed to the inlet position of the conduit defines a sloping shoulder to turn lateral blood flow from the conduit gently upwardly to define a gentle, circulatory flow of blood in an upper portion of the chamber. The chamber upper portion has a wall that carries projections to create blood flow eddys that slow the upward motion of bubbles present.
Patent CA-2179803-A1 (CA)
Inventor: WOLF JERRY
IPC: E05D1/02
Filed: 1996-06-24
Abstract: The present invention is a flexible hinge assembly.  The hinge component includes a flexible body having a flange extending lengthwise down each side.  The body has a groove cut into it extending lengthwise.  The body is inserted into an opening in a frame until the flanges engage the upper surface of the frame.  Halfway across the opening, two thin bars extend from each end.  These bars enter the groove in the top of the flexible body as it is inserted in the opening, thereby holding the flanges in contact with the surface of the frame.   The flexible body may be directly attached to an article to be hinged or it may be connected to an attachment device.

Inventor: WEERACKODY VIJITHA
IPC: H04L1/06
Filed: 1996-08-12
Abstract: The invention provides a method and apparatus for transmitting digital signaling formation to a receiver using a plurality of antennas. The invention involves applying a channel code to a digital signal producing one or more symbols. A plurality of symbol copies is made and each copy is weighted by a distinct time varying function.  Each antenna which are located at two or more base stations transmits a signal based on one of the weighted symbol copies. Any channel code may be used with the invention, such as a convolutional channel code or block channel code. Weighting provided to symbol copies may involve application of an amplitude gain, phase shift, or both. The present invention may be used in combination with either or both conventional interleavers and constellation mappers.
Patent CA-2184519-A1 (CA)
Title: Lightweight Vertical Lift Device for Windy Conditions
Inventor: SMITH DAVE W
IPC: B64F1/315
Filed: 1996-08-30
Abstract: The present invention is an improved wheeled, light-weight lift which meets standards for airline ground support vertical lift devices, specifically being capable of use on airport tarmacs in winds up to 90 mph. On and off-loading ramps are provided which are rotatable between an upright stored position and a horizontal working position. The ramps comprise a bridge structure supporting a plurality of louvred deck plates. Each louvre is linked to the others so as to remain oriented horizontal regardless of the ramps position for minimizing their aerodynamic profile and overturning moment. Outriggers are extendible from the frame so as to increase its base dimensions and thus the moment needed to overturn the lift. The outriggers retract into the frame to minimize storage. The outriggers are horizontally movable along their longitudinal axis to minimize the deployment space required. Lastly, it is preferable to increase the effective weight of the lift by providing wind deflection surfaces or airfoils to create a downward reactive force and thereby increase lift's resistance to overturning.

Title: Blood-pool imaging compositions use and method
Inventor: TOURNIER HERVE
IPC: A61K49/00
Filed: 1996-06-14
Abstract: The invention concerns NMR imaging contrast compositions comprising magnetically responsive species coupled to physiologically acceptable amphipatic organic substrate materials in the form of mixed micelles suspended or dispersed in a physiologically acceptable aqueous liquid carrier. The compositions are particularly useful for diagnostic investigations of the blood-pool. The invention also concerns the preparation of the mixed micelles, as well as of injectable compositions containing the mixed micelles as contrast agents for MRI purpose. Once injected, the mixed micelles of the compositions behave as imaging contrast enhancers, e.g. they will improve the quality and resolution of the electronically processed images obtained during MRI examinations of the circulation and/or circulation targeted organs. The compositions are formulated to protect the particles of the contrast agents from early removal by the reticulo-endothelial (RES) system of the liver and the spleen, so that they will stay in the circulation for a time sufficient to properly image the blood vessels and to be transported to selected organs. MRI imaging of the circulation and of targeted organs can strongly assist in diagnosing possible ailments in human and animal patients.

Patent CA-2206757-A1 (CA)
Title: A method and device for separating a substance from a liquid mixture by fractional crystallization
Inventor: BISCHOF RUDOLF
IPC: B01D9/02
Filed: 1997-06-03
Abstract: For the purpose of separating a substance from a liquid mixture by crystallisation, the inner walls of pipes in a crystalliser (S-1, S-2, S-3) are cooled by evaporating a liquid medium, the pressure of the gaseous phase of the medium being controlled in accordance with the temperature required for crystallisation.  In these conditions a layer of crystals forms on the outer walls of the pipes and can later be melted.  The previously-formed crystal layer is melted in one crystalliser simultaneously with crystallisation in another crystalliser.  This is done by introducing gaseous medium which is produced in a crystalliser during the said evaporation.  In addition, heat energy can be supplied to the crystalliser where melting occurs, in order to evaporate liquid medium there so that melting is accelerated.  The two simultaneously operating crystallisers operate respectively as an evaporator and as a condenser in a refrigerating unit (11), thus saving considerable energy compared with known crystallisation methods.
