Patent CA-2243789-A1 (CA)
Title: Handle cutter assembly
Inventor: ROBITAILLE LIONEL L
IPC: B26F1/22
Filed: 1998-07-20
Abstract: A new handle cutter assembly used in the packaging and shipping of things in cardboard boxes and the like. The inventive device includes a handle, a cutter for cutting handle slots, and an extendible knife. In use, the handle cutter assembly is pushed against a wall of material such as cardboard or the like. Since the surface area of the cutting edge initially contacting the surface of the material to be cut is reduced due to the high or pointed edges along with the low edges, the cutter readily penetrates the surface of the material.  As the cutter is pushed through the material, the low edges approach and eventually cut as well. The cutter 40 does not go completely around as in an oval, but rather it is shaped like a "C" and has one side left open. This remaining open side consequently does not cut the material adjacent to this area of the cutter 40 for the purpose of leaving the material intact and to be folded over. In some cases, this remaining flap can still be relied upon to hold material into the box and it can also serve as a more pleasant edge for the hand to lift against. The handle cutter assembly 10 can effectively be used either side up to create handle holes and flaps to the advantage of the user according to the material being carried or packed inside the box or object.
Patent CA-2245491-A1 (CA)
Inventor: TAKANOHASHI TOSHIKATSU
IPC: B60L50/16
Filed: 1998-08-21
Abstract: A torque shock alleviating device in a hybrid vehicle utilizing both an engine and an electric motor as drive sources, whereby a torque shock is not generated when the rich-spiking of the air-fuel mixture is carried out in order to restore the adsorbing ability of an NOx adsorbing device in the hybrid vehicle. When an engine is operated in a lean burn manner, NOx in an exhaust gas is adsorbed to an NOx adsorbing device provided in an exhaust passage. When the adsorbing ability of the NOx adsorbing device reaches a saturated level, a rich-spiking for temporarily enrichening the air-fuel mixture of the engine is carried out to restore the adsorbing ability of the NOx adsorbing device. When the output torque from the engine is increased by the rich-spiking, a regenerative braking force is generated in a motor, thereby moderating the increase in output torque from the engine by such regenerative braking force to alleviate the torque shock. An electric power generated by the regenerative braking is supplied for the charging of a battery.

Patent CA-2250726-A1 (CA)
Inventor: DUTTON ROBERT E
IPC: F04B49/06
Filed: 1997-04-04
Abstract: The operation of an oil well pumping unit control system (20, 200) is governed by a computerized automated control unit (88) that receives flow rate measurements from a Coriolis flow meter (28). The control unit causes production from a beam pumping unit (22) to cease when measurements from the Coriolis flow meter indicate a decline in the pump efficiency. The decline in pump efficiency indicates that a production fluid level (136) in the production tubing (108) has fallen below the uppermost point of travel for the pump plunger (122). Production from the well is, accordingly, shut-in to afford the reservoir sufficient time to build the pressure and corresponding fluid level that is required to recommence production operations.

IPC: B65D/
Filed: 1997-09-25
Abstract: A can with a cover comprises a pull ring (5) and a score line (7) adjacent the closing flange (8) of the cover, and a bottom closing flange (9). The nose (5b) of the pull ring (5) is spaced such a distance (x) from the weakening line (7) that two cans (1', 1 ) can be stacked atop one another without any risks of damaging the pull ring. When the handle part (5a) is lifted, the pull ring is displaced the distance (x) outwards towards the cover flange (8) before it perforates the cover through the score line (7). The resulting can is less vulnerable compared to known cans at the score line during handling and can thus withstand heavy vertical loads. Moreover more room is provided for a closing chuck at the seaming of the cover.

Title: Apparatus and process for forming prosthesis socket
Inventor: KRISTINSSON OSSUR
IPC: A61F2/80
Filed: 1997-10-29
Abstract: A prosthesis socket casting device includes a base member on which an elongated annular molding bladder is mounted, the bladder peripherally enclosing a generally centrally located casting area and extendable when inflated from the forward side of the base. The bladder is formed of a pliable, air impermeable, relatively non-stretchable sheet material enclosing, in cooperation with the base, an air chamber peripherally surrounding the casting area. The casting area includes an open residual limb receiving end and extends from such end to the base, and an inflation system for the bladder is provided. The casting device may be used in conjunction with a prosthesis suction socket that includes a tension member at its distal end connectable to the base member during a casting procedure. Moldable and settable prosthesis socket or other moldable casting material is placed over the suction socket and is compression molded by the inflated bladder while the casting material cures.   During the compression casting procedure, a tension force resulting from the bladder inflation pressure may be applied to the distal end of the suction socket to elongate and distend the distal area of the residual limb against which the casting material is formed under pressure. The bladder is rollable relative to the base member to provide ready access to the tension member connector carried by the base member.

Inventor: SILVERMAN ARTHUR
IPC: E06B3/44
Filed: 1999-08-24
Abstract: A storm-resistant window includes a mechanism for preventing the blowout of a movable sash when wind pressure pulls the sash outwardly. In a single hung window having a slidable lower sash, the mechanism consists of a first rib projecting downwardly from the bottom rail of the lower sash and a second rib projecting upwardly from the top of the sill member of the window frame. In a closed position of the window, the first rib lies inwardly adjacent the second rib such that, if wind pressure pulls the movable sash outwardly, the first rib will contact the second rib, preventing the bottom rail of the movable sash from moving outwardly. In an alternate embodiment, one of the ribs may be replaced with a channel, so that the remaining rib is received in the channel in the closed position of the window.

Le gaz chaud s'écoule à travers un générateur de vapeur (24) à récupération de chaleur de façon à produire de la vapeur, laquelle est dilatée dans une turbine à gaz (26) afin de produire de la puissance sur arbre. Une première partie du gaz chaud provenant du générateur de vapeur à récupération de chaleur est dilatée dans la section turbine (36) de la turbine à gaz, de manière à produire de la puissance sur arbre supplémentaire. Une deuxième partie (48) du gaz chaud provenant du générateur de vapeur (24) à récupération de chaleur est ensuite utilisée pour refroidir (56, 58, 60) la section turbine (36) de la turbine à gaz, après refroidissement et filtrage ultérieur dudit gaz. Puisqu'aucun fluide de refroidissement de la turbine n'est obtenu par soutirage d'air comprimé directement du compresseur, le flux de masse d'air chaud s'écoulant par le gazogène, et par conséquent le gaz chaud produit par celui-ci est maximisé, ce qui permet de maximiser la production de vapeur dans le générateur de vapeur à récupération de chaleur.
