Patent CA-2054507-A1 (CA)
Inventor: BONALDO JEAN M
IPC: A61B5/153
Filed: 1991-10-30
Abstract: ABSTRACT     A  blood  collection  device  wherein  a  double-ended cannula is retracted within the barrel of the device for storage and disposal.  The cannula is attached to the device immediately prior to use by being threaded into an aperture formed in a movable disc disposed within the barrel and rotated to a locked operating position for attachment of the cannula and use.  After use, the disc is counter-rotated to permit the cannula, mounted to the disc, to be longitudinally retracted completely within the barrel to a position in which the cannula is permanently locked by stopping the disc against further movement.  The disc aperture is threaded in the same direction as it is rotated to the operating position to avoid moving the disc out of the locked position during attachment of the cannula to the device.

Abstract: A loop threaded needle-suture device is disclosed wherein a surgical needle is provided with a pointed end and a drilled aperture extending axially of the butt end, and a length of flexible suture material is doubled upon itself to form a loop, both free ends of which are attached to the needle in the butt end aperture. The blunt end of the needle is deformed to form the aperture into an elliptical cross-section and the length of the loop is substantially greater than the length of the needle to facilitate insertion of the needle and suture material into tissue to be sutured, and looping the needle through'the suture material prior to tieing the suture material. Thus, the loop functions as a double suture. A method of forming the unique loop threaded needle-suture is disclosed.

Abstract: An end of an electrical connecting line for feeding a switching current is connected in an electrically conductive fashion, engaging through a recess of a contact support, to a contacting piece arranged on the contact support. In order to simplify the manufacture of such a contacting device, it is provided that the one end is connected to an extension which is formed by a stamping process in which the recess of the contact support is used as a shaping tool for the extension. It is thus ensured that the dimensions of the extension are matched in an optimum fashion to the dimensions of the recess. In addition, due to the production of t:he extension in the recess itself, the positioning of the end nearing the extension relative to the contact support or t;o its recess is dispensed with.

Patent CA-2071968-A1 (CA)
Title: Automatic plumb and level tool
Inventor: RANDO JOSEPH F
IPC: G01B11/26
Filed: 1991-10-18
Abstract: An automatic plumb, level and pointing tool uses a visible laser diode (42) to project a beam in any of three different modes through a beam exit window (30). The tool, approximately the size and shape of a tape measure, can be placed on one edge (14) to project a tilt-compensated vertical beam. Placed on another edge (16) 90· rotated, the tool projects through the same exit window a tilt-compensated horizontal beam. When laid on either of its larger flat sides (24), the tilt compensation becomes inoperative and the tool projects a beam which is fixed relative to the housing. In a preferred embodiment, separate pendulous or cantilevered mirrors (52) and (60) are used for vertical and horizontal tilt correction and are selected by the influence of gravity as the tool is laid on one edge or the other. In further described embodiments, two separate laser diodes (124a, 124b) may be used, or the laser tool may be integrated with other tools such as a tape measure or a squaring tool. A preferred cantilever beam tilt compensator achieves a wide range of accurate compensation through substantial tilt of the device in the horizontal mode.

Title: Traffic light
Inventor: GARDNER JAMES L
IPC: F21S8/00
Filed: 1991-05-09
Abstract: A signalling light (1) including a light source (2) and a fresnel lens (3) to provide an output beam. A reflective surface (4) partially surrounds the light source (2) and defines an opening directed toward the fresnel lens (3) which has an area substantially less than that of the fresnel lens. A portion of the fresnel lens is directly radiated through the opening by light from the source and the reflective surface (4) directs substantially the remainder of the light from the globe toward the fresnel lens. The reflective surface (4) is arranged to provide uniform illumination of fresnel lens (3) by the light source (2) thus effectively utilizing all the available lens area. An external lens (6) is included to provide different angular spread in the horizontal and vertical directions as required for a particular application. Although primarily designed for use with traffic signalling lights other warning or indicating lights are applicable to the invention.

Abstract: ABSTRACT OF THE DISCLOSURE              To automatically hitch a trailer to a motor vehicle, a first hitch section is mounted on the motor vehicle and a second hitch section is mounted on the forwardly extending tongue of the trailer.  The second hitch section comprises a hitch pin vertically mounted on the free end of the trailer's tongue and a guidable member formed of a ground-engaging lower portion and a pyramidal upper portion defining a vertex welded to the lower end of the hitch pin.  The pyramidal upper portion is formed with a V-shaped recess that slides on a ramp of the  first hitch section to guide the hitch pin toward a mechanism capable of detachably connecting the hitch pin to the first hitch section.   The pyramidal  configuration enables easy adjustment of the second hitch section to most of the trailer tongues.   The ground-engaging portion may include two legs normally placed into a ground-engaging position but mounted on the guidable member for pivoting when they hit the ground while the vehicle is moving.  An helicoidal spring is installed between a point of the legs distant from their pivotal connection and a point of the tongue distant from the tongue's free end to return the legs to their ground-engaging position following pivoting thereof.
Patent CA-2083554-A1 (CA)
Title: Customer order processing system
Inventor: FUYAMA SEIJI
IPC: G06Q30/06
Filed: 1992-11-23
Abstract: A customer order processing system includes a register terminal for sequentially transmitting customer order registered in the register terminal to a kitchen video controller, wherein the customer orders as received are sequentially displayed on a display device of the kitchen video controller.  Upon completion of preparation for a customer order by a person in charge, the display of that customer order on the display device of the kitchen video controller is erased by manipulating a control switch.  A time length between the reception of the customer order and the erasure thereof is measured and stored as service time data in the kitchen video controller.  The register terminal totalizes the service time data transmitted from the kitchen video controller to issue a management report.  With this customer order processing system, not only the service times taken for the disposition of customer orders can be managed but also speedy transmission of the customer orders to the kitchen as well as a reduction in the time taken for the preparation of the customer orders can be achieved.
Patent CA-2083805-A1 (CA)
Title: Method for cooling carcasses
Inventor: ENGLER SID
IPC: F25D3/11
Filed: 1992-11-25
Abstract: A method for chilling carcasses which comprises the steps of introducing a cryogenic fluid into a rotatable drum of a meat tumbler, the drum having inner walls which are cooled  by the cryogenic  fluid;  placing carcasses to be chilled inside the drum; and rotating the drum so that the carcasses contact each other and the inner walls until they are chilled to a sufficient degree.   The cryogenic fluid cools the drum to a temperature of approximately 32°F.  A small quantity of water may be introduced into the drum of the tumbler either immediately before or immediately after the introduction of the cryogenic fluid.  The water forms an ice layer on the inner walls to prevent the carcasses from sticking to the inner walls.   The primary chilling of the carcasses takes place between the tumbling carcasses and the cold inner walls and/or ice layer.  The carcasses may also be tumbled in the drum in an inert gas or vacuum atmosphere to massage surface moisture back into the carcasses.
