Patent CA-2452796-A1 (CA)
Inventor: STELIAROS MICHAEL KONSANTINOS
IPC: G06T19/00
Filed: 2002-07-08
Abstract: A method and apparatus for transmission and reception of three dimensional image data (14) is disclosed where vertex (12, 18) data, together with information on the displacement of vertices (18'A), is sent for reception an d reconstruction of a three dimensional object using a surface subdivision process. The method employed is characterised by all displacements for vertices (12, 18, 18'A) of a greater magnitude being sent, received and applied before all displacements for vertices (12, 18, 18'A) of a lesser magnitude, so that premature termination of the process results in varying degrees of surface (14) precision, but with image integrity. The transmissio n and reception process employs a SPHIT Tree applied to a three dimensional object rather than to a two dimensional surface (for which SPHIT Trees were created). The SPHIT Tree also eliminates the need for a sign digit for representing the direction of displacements of vertices. Data compression an d decompression is used, employing the Arithmetic Coding data compression meth od.

Abstract: The present invention is concerned with the driving mechanism of winding needles which dispense wire to form the wire coils of a dynamo-electric machine component. Generally, such wire winding is achieved by providing translational, rotational, and radial motions to the winding needle relative to a reference structure of the component. The present invention provides wire winding solutions for causing the winding needles to accomplish predetermined motions with respect to the component so that wire is predictably positioned on the component to form the wire coils. In particular, the present invention provides a driving mechanism with coaxial hollow shafts that impart the necessary motions to the winding needle. In one aspect of the invention, the inner shaft is able to mirror the rotation of the outer shaft to provide rotational motion to the winding needle. In another aspect of the invention, the outer shaft is able to impart both translational and rotational motion via coaxially disposed rotatable sleeves driven by motors. In yet another aspect, all of the winding motions are coordinated using a programmable control mechanism.

Title: Skate system for aiding in the movement of a building
Inventor: KERR PAUL
IPC: B60P1/00
Filed: 2004-02-19
Abstract: A skate system for use in the support and movement of carrier beams supporting a house or building from one location to another location. Lower surfaces of the skates ride and reside on or above a skate beam. Each end of the skate features a tubular receiving member and an elongated rod on each opposed side edge, whereby, when it is desired to connect a plurality of skates together, the elongated rod of one skate can be inserted into a corresponding tubular receiving member of another skate. The skate may be moved along the skate beam utilizing hydraulic jacks or other means to propel the skate (and the house) along the skate beam. If necessary, runner beams can be connected to the skate beams to assist in moving the house or building from one location to another location. Preferred configurations of the skate, in a plurality of connected skates, can later allow for lateral movement and transfer of the skate, supporting the carrier beams underneath the house, onto the placement location or foundation.

Abstract: L'invention concerne un procédé pour produire des pièces moulées, en particulier des noyaux de coulée, pour des moules utilisés pour couler des métaux en fusion. Selon ce procédé, dans une machine à tirer les moules (1), on charge, au moyen d'éléments de remplissage tels que des buses de tir (8) et une cloche de tir (6), une matière de moulage (F) contenant un liant inorganique dans une cavité (12) d'un outil de formage (10), cette cavité définissant la forme de la pièce moulée (K) à produire. On fournit ensuite de la chaleur à la matière de moulage (F) chargée dans l'outil de formage (10) pendant une période de durcissement pour solidifier la matière de moulage (F) par déshydratation. Pendant la période de durcissement, au moins les éléments de remplissage (6, 8) de la machine à tirer les moules (1), qui contiennent de la matière de moulage (F), qui se trouvent en attente pendant cette période de durcissement et qui sont chauffés en même temps par la chaleur rayonnante (W) dissipée par l'outil de formage (10), sont maintenus à un niveau d'humidité empêchant une solidification de la matière de moulage (F). Ce procédé permet de produire de manière fiable, avec un risque de défaillance limité, des pièces moulées pour moules de coulée à partir d'une matière de moulage contenant un liant inorganique.

Abstract: Essence of invention is piston superconductor cryogenic engine. It consists of plate made of superconductor material, device for supplying liquefied gas (liquid nitrogen) underneath the superconductor plate and magnet pin, located on upper surface of superconductor plate.   Principle of work is based on fact that superconductor generates inductance current with its own magnetic filed which makes magnet pin placed in that filed move away from it.   My invention would incorporate this phenomenon to build piston-like engine.  Piston-pin made of magnetic metal is placed upon superconductor plate of normal atmospheric temperature. (See Fig. 1 of enclosed drawing) Under the superconductor plate there is device which supplies liquid nitrogen to cool superconductor plate down to -180°C. When liquid nitrogen cools down the superconductor plate, it produces inductance currents, which in turn affect magnet pin and thrust it away from plate, which means up (Phase 1, Fig. 2). Then nitrogen supplying devise goes off quickly and temperature of superconductor plate goes up to normal (~+20°C). Inductance currents within the plate vanish, nothing affects magnet pin any longer, so gravity takes over and magnet pin goes down (Phase 2, Fig. 3). Then nitrogen supplying devise goes on again and cycle repeats. Magnet pin goes up and down with the same frequency nitrogen supplying devise goes on and off, so magnet pin works as a piston and with some auxiliary devise its up-and-down movements could be easily transformed into rotation.
