Patent CA-2135107-A1 (CA)
Title: Wheel attachment
Inventor: PESNYAK STEVEN M
IPC: B62B19/02
Filed: 1994-11-04
Abstract: A wheel attachment for wheeled vehicles whose primary purpose is to quickly, easily and inexpensively protect such vehicles from theft. The present invention is comprised of a casing having front and side panels to help position the wheel. A U-shaped bracing, which may be bent towards the front of the casing at an intermediate point to better grip the wheel, is attached to the rear of the casing in such a way that it may pivot back and downwards to lie on the ground and guide the wheel into the casing as the vehicle rolls forward. A similarly shaped bracing, bent towards the rear of the casing, is attached to the front of the casing in such a way that it may pivot back and downwards up to a point where the upper portion of this bracing is approximately 45 degrees from the vertical. The front bracing is held in this position as the wheel enters the casing in order to lessen interference with the wheeled vehicle when it rolls forward, and is pushed forwards by the wheel as the wheel enters the casing until the front bracing is fully in the upright position. The front bracing is prevented from moving too far forward by a bar passed through both side panels of the casing just forward of the front casing, and prevented from moving too far back by a stud in each side panel of the casing just behind the front bracing.   The wheel is secured in place by an rod-shaped locking mechanism passed through rings on the arms of the bracings facing away from the vehicle, which also prevents anyone but the owner from permitting the rear bracing to pivot. An extension spring is attached to each ring, and the locking mechanism passes through it as well. In order for this device to function properly for vehicles with low fenders, including most automobiles, the front bracing moves along grooves in the casing, allowing this bracing to lie flat as a wheel advances into the device, and to be pulled into locking position once the wheel is in place. This casing may be installed in parking spaces in garages and driveways. A further object of the invention is to convert such vehicles to winter use in snow, ice and unploughed roads, by removably mounting the casing on a ski which allows ease of movement through the snow.
Patent CA-2135607-A1 (CA)
Inventor: UHLEN MATHIAS
IPC: C12Q1/6869
Filed: 1993-05-12
Abstract: The invention provides a method of identification of the base in a target position in a DNA sequence wherein sample DNA is subjected to amplification; the amplified DNA is immobilised and then subjected to strand separation, the non-immobilised strand being removed and an extension primer, which hybridises to the immobilised DNA immediately adjacent to the target position; is provided; each of four aliquots of the immobilised single stranded DNA is then subjected to a polymerase reaction in the presence of a dideoxynucleotide, each aliquot using a different dideoxynucleotide whereby only the dideoxynucleotide complementary to the base in the target position becomes incorpored; the four aliquots are then subjected to extension in the presence of all four deoxynucleotides, whereby in each aliquot the DNA which has not reacted with the dideoxynucleotide is extended to form double stranded DNA while the dideoxy-blocked DNA remains as non-extended DNA; followed by identification of the double stranded and/or non-extended DNA to indicate which dideoxynucleotide was incorporated and hence which base was present in the target position.

IPC: G06F9/06
Filed: 1995-01-13
Abstract: A method and system for aggregating objects within a computer system are provided. In a preferred embodiment, the method aggregates an enclosed object within an enclosing object. The enclosed object has an object management interface and an external interface, while the enclosing object has a controlling object management interface. The controlling object management interface and the external interface of the enclosed object have query function members for receiving an identifier of an interface and for returning a reference to the identified interface. A preferred embodiment creates an instance of an enclosing object and an object to be enclosed. In static aggregation, the controlling object management interface of the enclosing object knows in advance how to return an identifier to the external interface of the enclosed object. In dynamic aggregation, an object to be enclosed is added to the enclosing object after the enclosing object is instantiated. Once aggregated, when the query function member of the object management interface of the enclosed object receives an identifier of an interface, it invokes the query function member of the controlling object management interface forwarding the interface identifier and returns the reference to an interface returned by the invoked query function member of the controlling object management interface. In dynamic aggregation, rules for determining to which interface to return a reference can by added to the enclosing object and used by the query function member of the controlling object management interface.

Title: Electric motor having permanent magnet brake
Inventor: DU HUNG T
IPC: H02K23/68
Filed: 1995-01-24
Abstract: An electric motor such as a universal series wound  motor  having  permanent  magnetic  segments mounted within slots  formed in the poles of the stator.     The  permanent  magnets  are  precisely positioned and securely retained within the slots with an injected metal bonding agent having very stable  mechanical  properties  even  under  severe temperature conditions.  The permanent magnets ensure that a predetermined level of braking current exists when the armature is short circuited to effectively dynamically brake the motor.  The AC supply signal is rectified to prevent demagnetization of the permanent magnets and to reduce overheating of the permanent magnets caused by the continuous changing of polarity of the AC supply signal.  An alternative embodiment describes a modified armature core construction that sufficiently reduces armature eddy current loss to offset  the  additional  heat  resulting  from  the permanent magnet braking members.

IPC: H01L21/306
Filed: 1995-04-12
Abstract: A semiconductor device comprises a monocrystalline silicon wafer having a major surface lying in the <100> crystal plane.  Disposed on the surface is a mesa having a generally square cross-section with generally rounded corners.          The mesa has four main side walls each having a slope of around 45 degrees with respect to the base plane of the mesa, and the horizontal edges of the main side walls are disposed at an angle of at least around 12 degrees to the <111> directions on the wafer surface.  The corners of the mesa each comprises a number of surfaces also having slopes of around 45 degrees and one surface having a slope of around 54 degrees.          A high-low (N+ N? or P+ P?) junction is disposed within the mesa and makes a continuous line intercept with the mesa side walls around the entire periphery of the mesa.  Except for exceptionally small deviations of no great significance, the high-low junction intercept is at a constant height location entirely around the mesa periphery.  The mesa is formed by anisotropic etching using a mask having main sides disposed at an angle of at least around 12 degrees to the <111> directions and rounded corners.

Title: Damped One-Way Self-Closing Gate
Inventor: MCGUIRE JOHN D
IPC: E05F1/06
Filed: 1995-05-05
Abstract: A one-way self closing gate such as may be used in retail stores, airports or libraries is provided with an inclined helical ramp mechanism by which opening of the gate also causes lifting of the gate arm relative to the gate base. When released the gate will tend to close itself under the force of gravity.  To   augment this  gravity force a spring  is provided which is compressed as the arm rises relative to the base.  So that the gate does not close too quickly a screw presses a nylon slug against the turning shaft of the gate.  When the gate is closed a force applied to open the gate in the contrary direction to  that intended is  resisted by abutment of a generously welded internal stop against a generously welded internal upright.  In an alternate form this resistance function in the closed position is performed by an adjacentpost positioned to intercept the motion of the moving barrier. In all cases the internal  mechanism of the gate is enclosed in a housing to prevent injury to children's fingers.
