Title: One hand putter with pendular principle
Inventor: YANG KUNG CHI
IPC: A63B53/04
Filed: 1995-05-16
Abstract: A one hand putter with the pendular principle is invented to enhance the accuracy and consistency of putting at the golf green area. The present invention is composed of an elongated pyramid-shaped putter head and a round club shaft which is mounted perpendicularly at the centre of the top of the putter head with a mountain like head shoulder and a connector between them. The putter head is a hollow structure with six walls, i.e., two end walls, the wall of the putting blade, the wall opposite the putting blade and the walls of the top and bottom portion of the putter head. The thickness of these six walls varies. The thickest walls are located at the two symmetrical end walls, then the wall of the bottom portion, then the wall of the putting blade or the wall opposite the putting blade and then the thinnest wall of the top portion of the putter. The arrangement of the six walls with a twisting connector facilitates locating the centre of gravity within the putter head which increases the stability of the back and forward putter swing. The grip of the putter is flat on the opposite side of the putter blade. The grip area is a hollow chamber into which can put steel bars of various weights acting as stabilizers to balance the putter back swing. The present invention reduces the troublesome two handed putting method with a curvature swing and the problem of two hand coordination. The result of using the present one hand invention will be more accuracy and consistency while putting than the two handed method can achieve. A better score in your golf game can be expected and achieved with the use of this invented putter.
Patent CA-2149844-A1 (CA)
Inventor: STURTEVANT THOMAS M
IPC: B60R13/01
Filed: 1995-05-19
Abstract: A process for selectively forming an antislip surface on a product thermoformed from a plastic sheet is applied to truck bed liners, for example. The surface of the plastic sheet of HDPE or other thermoplastic material is cleaned and masked, to prepare a good molecular bonding surface on selected surface areas. A sprayable or liquid polymer selected to achieve desired charac teristics of hardness and toughness without brittleness, such as a thermosetting elastomeric polymer, is formed into droplets, which are sprayed or otherwise applied onto the selected surface area. The droplets form a stippled pattern of primarily separate bumps across the selected surface area to be treated, occupying substantially less than 50% of the exposed area. After partial hardening of the bumps, the plastic sheet is thermoformed at thermoforming temperatures to produce the thermoformed product.      Thermoforming tightly bonds the bumps or droplets to the thermoplastic sheets material, hardens the droplets forming macroscopic asperities, increases or enhances the three dimensional surface relief, and explodes some droplets with entrapped air to increase surface roughness.

Patent CA-2164651-A1 (CA)
Title: Head-lock handle
Inventor: MERKEL WARREN HANK
IPC: B25G1/10
Filed: 1996-08-12
Abstract: This invention can be best summarized as a two piece, synthetic sledgehammer handle that incorporates two independent, mechanical locking mechanisms that affix the head to the handle. A moulded Guard is positioned near the butt of the handle.   The Primary Locking Tabs are a moulded part of the handle itself and can be referred to as external. There are two separate tabs and they are located across from one another along the outer edges of the Mounting Core (the portion that is inserted into the hole in the center of the head). They are manually pinched together to facilitate the insertion of the Mounting Core. Once the head has been tapped on all the way, the tabs spring outward, thus locking the head down.   The Main Lock is the second piece in the design and like a traditional wedge, it is driven down into the top of the Mounting Core. However, unlike a wedge, it is shaped tocorrespond with an internal Locking Bay that "captures" the lock and prevents it from ever working its way back out.  In addition to being permanently locked in place, the head of the Main Lock has a circumference larger than that of the hole in the head, thereby forming a Cap.   The Guard is a moulded, quarter-circular shaped extrusion near the butt of the handle that has a three-fold function. First, it prevents the hand from slipping off when swinging the hammer. Second, it can be hooked into a belt for transportation (applicable on the short-handled versions). And finally, it can be conveniently hung up when not in use.

Abstract: La présente invention concerne des cellules aptes à la transplantation et utilisables pour l'administration d'une substance d'origine génique à un sujet allogène ou xénogène. Lesdites cellules, modifiées de façon à exprimer une substance d'origine génique, comportent au moins en leur surface un antigène stimulant une réponse immunitaire contre la cellule chez un sujet allogène ou xénogène. Préalablement à l'administration des cellules modifiées, l'antigène en surface cellulaire, par exemple un antigène MHC de classe I, subit une modification lui faisant bloquer le rejet de ladite cellule par un sujet allogène ou xénogène. De préférence, la modification de l'antigène s'obtient en le mettant en contact avec soit un anticorps, soit un fragment ou un dérivé de cet anticorps, par exemple un fragment de F(ab)'¿2?. La modification de l'antigène en surface des cellules préalablement à l'administration bloque la réaction immunologique de rejet de la cellule et évite d'avoir à soumettre la sujet à une immunosuppression systémique.

Patent CA-2189460-A1 (CA)
Inventor: SCUDDER JAMES A
IPC: F24V30/00
Filed: 1995-05-26
Abstract: An outer container for holding a material, such as a food, beverage or medicine with a sealed thermic module inside the container. The thermic module contains chemical reactants that mix upon actuation of the container by a user. Mixing of the reactants produces an exothermic or endothermic chemical reaction, depending upon the reactants selected. The contents of the outer container (10) surround a portion of the outside surface of the thermic module (14), thereby facilitating conducting of heat. The thermic module (14) has a hollow module body (18) that is closed at one end and a module cap (20) that seals the other end of the module body. The module body (18) contains the solid reactant, and the module cap (20) contains the liquid reactant. The module cap has a tubular section with a flexible member (22) closing one end and a breakable barrier (34) closing the other end. With the exception of the barrier, the cap is of unitary construction. The cap (20) has one or more integrally formed prongs (24) extending from the inner surface of the disc (22) toward the barrier (34). The prongs (24) move in an axial direction toward the barrier (34) and may also spread apart radially when the outer surface of the flexible member (22) or an actuator connected to it is depressed by the user's finger. The dual motion of the prongs (24) in both axial and radial directions promotes complete puncturing of the barrier (34) and thus fast mixing of the reactants.
