Patent CA-2071085-A1 (CA)
Inventor: MCCARTHY DONALD J
IPC: F16C29/04
Filed: 1992-06-11
Abstract: An improved linear bearing assembly comprising sets of guides (ways) for guiding rolling elements (ball bearings or rollers) constrained within a cage. Typically, two sets of rolling elements and cages are used between a moving part and a stationary part. Each set has four resilient elements (springs) with one end of each spring anchored to the cage and with the other ends of two springs anchored to the stationary way or part and the other ends of the other two springs are anchored to the movable way or part.  This arrangement provides a restoring spring force that gradually forces the cage to its correct tracking position.  If the cage is tracking properly, the spring forces cancel out and there is no inherent rubbing in the restoring mechanism.

Abstract: A door handle assembly including an escutcheon plate,  a  handle  secured  to  the  outer  face  of  the escutcheon plate, and a turn lever mounted on the outer face of the escutcheon plate.  The turn lever includes an actuator portion which passes through a transverse slot in the escutcheon plate and through an actuator hole in the door for access to the actuator of a latch assembly so as to move the latch assembly between latched and unlatched positions in response to turning of the turn lever.   The actuator portion of the turn lever may be moved laterally within the slot in the escutcheon plate to accommodate door installations in which the actuator hole is centered with respect to the mounting holes for the escutcheon plate as well as installations in which the actuator hole is offset with respect to the mounting holes and the lever portion of the turn lever acts in both installations, and in all positions of the actuator portion of the turn lever, to completely mask the slot so as to preserve a pleasing exterior appearance for the door assembly.   The slot also allows the  same door assembly to be used for either right handed or left handed installations.  The slot is provided offset with respect to the longitudinal midpoint of the escutcheon plate so as to accommodate the vast majority of door installations and a further slot is provided on the midpoint of the escutcheon plate to accommodate those installations where the actuator hole in the door is centered with respect to the mounting holes in the door.

Title: Atherectomy cutter with a positive attack angle
Inventor: RADISCH HERBERT R JR
IPC: A61B17/3211
Filed: 1992-09-09
Abstract: A rotatable atherectomy cutter is provided with a body and a pair of blade elements.  The blade elements are mounted on the periphery of the body and extend distally therefrom in a linearly convergent manner.   Each blade element has a flat planar outer face with two linear longitudinally-exposed edges, one of which is defined as the cutting edge and the other of which is defined as the trailing edge.   The cutting and trailing edges are positioned at a maximum radial distance from the axis relative to the remainder of the blade element to define the outermost rotation surface of the blade element. Accordingly, contact between the blade element and the stenosis is limited to the edges during rotational operation of the cutter, while a clearance is maintained between the stenosis and the outer face.  The clearance defines a positive attack angle that enables the cutting edge to more effectively cut away the plaque of the stenosis.

Abstract: IMPROVED BINGO GAME CARD               ABSTRACT OF THE DISCLOSURE         An improved bingo game card Bet is provided wherein each of the individual game cards includes first numerical indicia in a location outside the 25-square playing region of the usual bingo game which indicia constitutes one or more Wild Numbers.  In the game card as distributed, the numerical indicia and preferably also the playing region are covered in some secure manner so as to obscure them from view so that, prior to distribution to a player, unauthorized tampering in an attempt to preview the numerical indicia cannot be carried out without detection.  In addition to being used to play the traditional bingo game where numbers are announced by a caller, the improved game cards create a number of immediate or instant winners as a result of additional free spaces generated by the Wild Number or Numbers.  Furthermore, a bonus number adds to the excitement of the game, e.g. by providing an additional free space or providing basis for either an enhanced award or for a separate award of a large jackpot on a less frequent basis.

Title: Pulse responsive device
Inventor: MATHEWS GEOFFREY
IPC: A61B5/0245
Filed: 1991-05-28
Abstract: A pulse responsive device, e.g. a pulse rate meter or pulse oximetry device comprises a light emitter (20) and a light sensor (21) for receiving light from the emitter after transmission through or reflection from body tissue, to give an electrical signal varying according to blood flow pulsations. A movement transducer gives an electrical signal representing body movements or vibrations but independent of blood flow pulsations: this transducer may comprise a light emitter (22) and sensor (23) responsive to a different wavelength from the elements (20, 21). The device compares the two electrical signals to cancel out the movement or vibration noise from the signal from the sensor (21).

Abstract: CONTROLLED GAS TRAP SYSTEM      (D# 91,021 - F) ABSTRACT OF THE DISCLOSURE         An improved gas trap for mud logging is vertically mounted such that its lower end is constantly beneath the surface of mud flowing in a tank.  The mud is drawn into the housing where it is agitated to release the entrained gases which are drawn off for measurement.  The spent mud is returned to the tank through a mud exit port and related pipe to a point below the level of the mud and remote from the mud intake to the gas trap.       This gas trap is insensitive to mud level changes and is relatively free of maintenance requirements.     B:\91021,APP

Abstract: A synthetic array comprising a moving magnetic sensor that provides a signal representative of an array of magnetic sensors is coupled to a digital signal processor is used to break a magnetic dipole field into its components, and a magnetic, signature of the present magnetic field is created. Predicted dipole signatures are precomputed for multiple magnetic orientations of the dipole at each of a plurality of range locations, expressed in terms of Anderson functions, which are a set of equations that decompose the magnetic field in each of the magnetic response locations, and are stored in a lookup table for reference. Input data measured by the moving synthetic array are processed and each magnetic value is predicted to process against background noise. A long term time average consistent with the relative motion of the dipole is computed using band-pass filtering of the signals from the synthetic array. The bandpass filtered data is used to update the predicted data so that anomalies and other non-dipole data is removed from the signals that are processed. The data are then expressed in terms of Anderson functions. The data are matched filtered, wherein it is correlated with the stored pre-computed predicted dipole signatures. The correlation yields a set of values that is then thresholded. If a dipole is present at any of the locations, then the correlated normalized value computed as stated above will be higher than the chosen threshold. The dipole locations that are above the threshold are then displayed on a monitor showing the relative location and dipole orientation.

Abstract: A plurality of 2-dimensional images of different visual directions when an object to be displayed is seen from different directions are inputted and a phase distribution at a hologram forming surface is calculated.  The calculated phase distribution is expressed on the hologram forming surface  of a phase expressing section  using a display.  A reproduction light is irradiated and converted into an optical wave front, thereby displaying a solid image.  The 2-dimensional images are inputted by photographing an object by cameras.  The 2-dimensional images can be also formed by interpolating calculations from the two 2-dimensional images which were actually photographed.  The 2-dimensional images which are used in the phase calculation  are subjected to the enlargement, reduction, and movement of the coordinate position, thereby adjusting the size and position of the solid image.  The phase distribution  is calculated from a plurality of 2-dimensional image  every red, green, and blue components, and the reproduction light of each color is irradited, thereby displaying a color solid image.
