Patent CA-2170587-A1 (CA)
Inventor: HO WING
IPC: G08B13/24
Filed: 1996-02-28
Abstract: A marker for a harmonic electronic article surveillance system includes three wires of magnetic material arranged in parallel. The material has a magnetic hysteresis loop with a large Barkhausen discontinuity such that, upon exposure of the marker to an external magnetic field whose field strength in the direction opposing the instantaneous magnetic polarization of the marker exceeds a predetermined threshold value, there results a regenerative reversal of the magnetic polarization in the material. The three wires are coupled at opposite ends thereof by magnetic charge spreading elements formed of a highly permeable material so that all three wires exhibit the regenerative reversal simultaneously on exposure to the above--described magnetic field. The resulting harmonic marker can be formed with a substantially shorter over-all length than previously practical markers of the harmonic type while providing a signal of comparable amplitude.

Title: Laparoscopic surgical clamp
Inventor: SACKIER JOHATHAN M
IPC: A61B17/122
Filed: 1994-10-20
Abstract: A surgical clamp (10) combination includes a clamp movable between a free state and operable state, the clamp including a pair of jaws (36, 38) which can be operated to occlude a body conduit (32).

A shaft (58) is disposed within the tube and movable between an extended position to engage the clamp in the free state and a retracted position to releasably hold the clamp in the operable state. With the clamp in the operable state, the shaft is rotatable by operation of a handle and aladdin screw (47), to alternatively rotate in opposite directions to open and close the jaws of the clamp.

Patent CA-2177263-A1 (CA)
Title: Retractable fluid collection device
Inventor: SHAW THOMAS J
IPC: A61B5/154
Filed: 1994-12-06
Abstract: A permanently automatically retractable fluid collecting device (10) has an elongated outer protective tube member (12) having a front end (14) with a port (15) and a coaxial telescoping plunger (16) having a forward end (26) for frictionally engaging a needle holder (20) for a cannula needle (32). The plunger is slidingly mounted in the elongated tube member for selective movement in an axial direction toward and away from the front. The front end of the plunger has an opening having inwardly facing surfaces (66) for frictionally engaging outwardly facing surfaces (68) of the periphery of the needle holder (20) along a slidable axially oriented interface. When the plunger is moved forward to extend the needle from the port, a catch (48, 50) holds it in a first position. Biasing force is applied to the needle holder being frictionally held in the front of the plunger. A collection tube (72) is installable in the opening at the rear (40) of the plunger. After taking a sample and removing the collection tube, a plunger cap (42) is repositioned to allow the plunger to be moved from the first position toward a second position causing sliding separation of the plunger from the needle holder along the slidable interface. The biasing force overcomes remaining frictional holding force at the sliding interface to cause immediate and permanent retraction of the needle holder into a cavity comprising a retraction space (17) within the plunger.

Title: Nip pressure sensing system
Inventor: MOORE ROBERT H
IPC: G01L5/00
Filed: 1996-05-30
Abstract: A roll sensing system for measuring the pressure distribution and nip width in a nip roll press.  The sensing system comprises a strip having sensors thereon, the strip being placed in a nip press, for sensing the pressure at several locations therealong.          At one end of the strip lies electronics associated with the sensors.  The electronics communicate with an optional multiplexer and a bidirectional transmitter for signal transmission to an external  signal conditioner and an external computer.     The computer determines pressure values and nip width values at various locations along the strip, and communicates with a display which provides a visual, graphical and/or numerical data to the operator.          Optionally,  a control system can be in communication with the transmitter or the computer to initiate crown corrections in response to pressure or nip width readings.

Title: Spray gun type electrostatic painting apparatus
Inventor: LEE HOYANG
IPC: B05B7/08
Filed: 1996-01-17
Abstract: A spray gun type electrostatic paint coating machine which is capable of improving quality of coated surfaces, the coating machine including an air nozzle (8) and a paint nozzle (21) respectively provided at the fore end of a spray gun body (6). The spray gun body (6) and the air nozzle (8) are made of an electrically insulating material, while the paint nozzle (21) is made of a metallic material including a paint spouting orifice (21C) which is projected on the front side through the air nozzle (8). The paint spouting orifice (21C) is connected to ground through a paint supply passage (10) to serve as a grounding electrode. Sprayed paint particles are at the earth potential, so that they are less susceptible to influences of dielectric polarization and negatively charged quickly by the high negative voltage of the external electrode. As a consequence, sprayed paint particles are prevented from depositing on the air nozzle (8) or other negatively charged surfaces and falling down in the form of discrete dot-like driblets to contaminate a coated surface.

Patent CA-2208300-A1 (CA)
Title: Tail gate
Inventor: STONEMAN DAVID J
IPC: A01K1/06
Filed: 1997-06-19
Abstract: A tailgate for preventing cattle from backing up while in a guide chute is described. The tail gate comprises a tube, angle brackets and a gate section. The angle brackets are arranged to be fitted into the tube such that the angle brackets can be attached to horizontal or vertical surfaces. The gate section is arranged to pivot about the tube from one side of the tube only so that cattle may pass freely from one side of the tail gate but are prevented from passing from the opposite side. As a result of this arrangement, cattle contacting the gate from the opposite side of the tail gate will reflexively remain in place. This in turn prevents the cattle from backing up and speeds up the flow of cattle through the chute. The tail gate is arranged to be fitted into chutes of various widths at any point along the chute fitting and the height of the gate section can be varied for use with animals ofdifferent sizes.
