Abstract: An apparatus for placing corner protectors having elongate panels meeting at right angles onto vertical corners of pallet loads having vertical sides defining vertical corner comprises a magazine to hold a supply of the corner protectors and mechanisms for removing one corner protector from the magazine, transferring the corner protector to a position where one of its panels is disposed in close proximity to a vertical side of such a load, and displacing the corner protector until its other panel engages another side at the same corner of the load.  In the magazine, the corner protectors extend vertically and are nested within one another.  Also, the corner protectors are guided forwardly along a supporting chute.  A wheeled carriage having an upright member is mounted operatively in the chute and prevents the corner protectors from tipping backwards.

Patent CA-2098153-C (CA)
Inventor: DANISCH LEE A
IPC: G01B11/16

Granted: 2000-03-14
Abstract: A curvature or bending and displacement sensor is composed of a fiber optic or light wave guide, for attachment to a member or members being curved or displaced. Light is injected at one end and detected at the other end. Curvature of the fibre results in light loss through an emission surface or surfaces, sometimes in conjunction with a superimposed curvature in a plane other than that of the curvature to be measured, this loss being detected. The loss of light detection is used to produce indication of curvature or displacement. The light emission surfaces extend in a substantially circumferential direction, or in a substantially curved axial direction when in a curved portion of a curved guide. The placement, shape and configuration of the emission surfaces allows adjustment of the linear range of measurement, the overall throughput of light, and the length over which curvature is measured. Two or more light guides can be oriented to given indication of direction of curvature or displacement.

Abstract: A trocar and trocar obturator assembly having an obturator and a locking mechanism responsive to proximal, axial movement of the trocar obturator is disclosed. The trocar obturator has an elongated obturator shaft having a proximal end and a distal end with a piercing tip mounted thereto. The proximal end of the trocar obturator shaft is slidably mounted in a handle such that the obturator shaft is moveable axially. A protective safety shield having a distal end and a proximal end with a flange member mounted to the proximal end is slidably mounted on the trocar obturator. The safety shield is moveable, axially, between an extended distal position and a retracted proximal position. The protective safety shield is disposed concentrically about the obturator. A lockout arm for locking the safety shield in a locked extended position is mounted in the trocar obturator handle. An actuating collar member is-mounted to the proximal end of the obturator shaft in the obturator handle and is moveable with the obturator shaft. The obturator collar disengages the locking arm when moved proximally and engages the locking arm when trocar is armed. The trocar obturator assembly may be concentrically mounted in a trocar cannula having a passageway for receiving the trocar obturator and safety shield. The locking mechanism is actuated by proximal, axial motion of the obturator.

Title: Shingles
Inventor: ILNYCKYJ PETER
IPC: E04D1/28
Filed: 1994-10-14
Granted: 2005-02-22
Abstract: A roofing shingle is conveniently formed from a square sheet metal blank. One corner of the blank is provided with a pair of open ended, back to back U shaped slots transverse to a diagonal passing through that corner. The two sides intersected by the slots are downwardly turned to form a small margin, and the other two sides are upwardly turned to form a margin of similar width to the downwardly turned sides. The corner is also downwardly folded above the slots to form a margin of similar width to the other margins, and below the slots it is folded so as to be generally parallel to the central area of the shingle. A shingle support preferably of foamed sheet polystyrene is disposed on the under surface of the shingle. The shingles are laid course by course on a pitched roof in a diamond configuration, a shingle of an upper course engaging the respective downturned edges of two adjacent shingles of a lower course in the U shaped slots to lock the lower corner of the upper shingle mechanically in position. Nails or screws may be used to secure portions of the upper shingle remote from the mechanically locked corner. A downwardly turned side of the upper shingle and an upwardly turned side of a lower shingle will form a seal to resist the penetration of driven rain and capillary action. The shingled roof has an appearance of thickness, while heat transference between shingles is generally reduced in comparison to flat shingles.

Abstract: L'invention se rapporte à une unité de valve médicale, qui comprend un corps de valve traversé par un passage pour fluides, un élément de valve (32), et un organe de sollicitation (46) disposé dans le passage pour fluides. L'élément de valve est conçu pour venir se plaquer hermétiquement contre une surface scellante du passage pour fluides (42) et l'organe de sollicitation (46) est conçu pour solliciter l'élément de valve à venir se plaquer contre la surface scellante (50). Une telle valve médicale peut être utilisée sans aiguille, afin d'éliminer les risques associés aux blessures dues à la pointe des aiguilles. Dans les applications où il est pratique d'utiliser une aiguille (par exemple avec des médicaments préconditionnés), la valve médicale décrite ici permet l'utilisation d'une aiguille pour l'administration du médicament. Dans un premier mode de réalisation, l'organe de sollicitation (46) est conçu solidaire avec la partie de tête de l'élément de valve (32). Dans un autre mode de réalisation, l'organe de sollicitation est conçu séparé de la partie de tête de l'élément de valve et il est constitué par un ressort métallique.

Title: Projectile and launcher toy
Inventor: ROBINSON ALLAN BROOKS
IPC: A63H27/00
Filed: 1994-04-14
Granted: 2005-07-05
Abstract: The toy is composed of a projectile and a tube for launching the projectile into the air. The projectile has a pair of wings symmetrically disposed about a longitudinal axis . The leading edges of the wings normally extend outwardly at an oblique angle from a nose which defines the forward end of the projectile. In that position the projectile will fly through the air.      The wings are spring-biased into the position for flying.      When a manual force opposed to the biasing means is applied to the wings, they fold inwardly with resulting pivoting of the leading edges toward each other. When the wings are closed the projectile is in a pre-launching position.      The projectile is launched into the air by means of a tube which is hollow and open at one end through which the projectile exits from the tube.

Abstract: In order to extend the useful life of electrical storage battery cells under float voltage charge it is advisable to maintain the polarization of the positive plates (22) of the cell relative to a reference electrode (26) in the cell at a predetermined level. This invention provides a sensing and controller circuit (20) which drains minute amounts of current from the positive cell plates when the polarization rises above the desired level and thereby prevents plate corrosion and loss of electrolyte. The present invention may be combined with a circuit for increasing cell polarization levels to provide a system for maintaining battery cells at optimum polarization levels over extended float charging periods.
