Patent CA-2162872-A1 (CA)
Title: Shot wad with highly collapsible hinge portion
Inventor: GARDNER ROBERT J
IPC: F42B7/08
Filed: 1994-05-03
Abstract: The invention uses a pair of curved opposed diagonal bars (24, 26) between a shot wad (12) and shot cup (16). The bars (24, 26) (deformable resistance members) buckle in the radial direction and end up basically flat between the shot wad (12) and shot cup (16) to give surprisingly and unexpectedly high amounts of collapse (80 % or more). This allows the space between shot wad (12) and shot cup (16) to be decreased significantly without sacrificing cushioning.

Patent CA-2163530-A1 (CA)
Inventor: MAINE NELSON D
IPC: B26B23/00
Filed: 1995-01-05
Abstract: An improved wood-splitting maul (10, 30) wherein the striking edge is at an improved angle (2, 45). The improved angle (25, 45) makes the maul easier to use, more efficient, and provides less shock to a user's body. The improved angle (25, 45) is defined by a straight line (26, 46) essentially running along the length of the splitting edge (20, 40) (or hammer face) to a point at a pivot point (27, 47) defined between about the bottom end of the handle (14, 34) where the maul is grasped while in use and the approximate location of the elbow of the user of the maul and a line along the longitudinal axis (28, 48) of the handle (14, 34). The exact degree or the absolute optimum value of the angle is a function of the handle length, the distance of the splitting egde (20, 40) (or hammer face) from the handle axis and the size of the user of the maul. The efficiency is improved to such a degree that a handle (14, 34) of only 28 inches in length provides improved performance in the manual splitting of wood.

Patent CA-2165245-A1 (CA)
Inventor: ACCORSI MARCO
IPC: B29C65/02
Filed: 1995-12-14
Abstract: A method for producing containers, such as bottles or the like, with a film made of thermoplastic synthetic material, and to an apparatus for performing the method. The process comprises: a step for thermally bonding two strips of film made of thermoplastic synthetic material that face one another, so as to form, between the two strips of film, pouches that are open at a longitudinal edge of the strips of film; and a thermoforming step, during which a segment of the two strips of film, in which the pouches are formed, is inserted in a forming mold that is provided with molding cavities located at the pouches, and a pressurized fluid is injected into the pouches through their open side to form them, by plastic inflation,  inside the molding cavities. The thermal bonding of the two strips of film that form the pouches is correlated to the dimensions of the molding cavities, so that the thermal bonding line, which delimits the pouches, lies inside the corresponding molding cavity at a preset distance from the walls of the molding cavity when the strips of film are inserted in the forming mold. The thermoforming step is followed by a step for blanking at least the portions of the strips of film that protrude from the base and from the lateral surface of the contour of the containers that are thermoformed at the pouches.

Patent CA-2167423-A1 (CA)
Title: Shifting tool
Inventor: CONSTANTINE JESSE J JR
IPC: E21B23/04
Filed: 1996-01-17
Abstract: A shifting tool is provided which is preferably hydraulically actuated. A built-up hydraulic force overcomes a retaining piston, which, in turn, frees up a pivoting linkage whose movements are opposed by a coil spring. The coil spring urges the pivoting linkage outwardly where contact can be made with the internal groove on a shifting sleeve. The shifting tool can be run in with the linkage in the expanded position since the parts are configured to allow the linkage to retract to clear any internal obstructions before reaching the shifting grooves in the shifting sleeve. The pivoting action of the grip on the groove in the shifting sleeve increases the gripping force when jarring occurs. The parts are configured so that there is a minimum of movement of shifting parts which have seals to further reduce potential wear on pressure seals. A compact design is provided which can be useful on sleeves with a range of internal bores. The coil springs used in the preferred embodiment, which act against the linkage, can be easily replaced to adjust the force of engagement with the internal groove on the shifting sleeve.
