Abstract: An improved staple for use with an endoscopic stapler has arms which are curved toward each other such that the staple may be crimped so as to cause the arms to move toward each other and thereby lock the staple into place. This crimping action substantially mitigates the likelihood of the staple inadvertently pulling out. The staple also has an abutment bend formed therein to serve as a detent and thereby secure the staple within the jaws of an endoscopic stapler. An endoscopic stapler for effecting use of the improved staple is also disclosed. The endoscopic stapler generally comprises an elongate tubular section which may be inserted through an endoscopic incision into a human body; a handle portion having a trigger for effecting the stapling process; a pair of jaws disposed at the distal end of the elongate tube for positioning and crimping a staple in place; a feed mechanism for advancing a series of staples to the jaws; and a means for selectively adjusting the amount of crimp imparted to the staple.

Abstract: Wrench for continuous driving engagement with a rotatively driven element such as a screw, bolt or nut, which is particularly suitable for use where the ends of the driven element are not accessible and in applications where space for manipulation of the tool is limited such as in spinal fusion surgery. The wrench has a peripheral driving element which can be engaged from the side with the driven element, and in some embodiments an articulating handle which enables the wrench to rotate the driven element through a substantial angle with only a few degrees of handle movement.

Abstract: A reciprocating saw includes a body and a slider supported by the body such that the slider is slidably movable in a longitudinal direction of the body and is pivotally movable in a vertical direction. A first motion conversion mechanism is operable to convert the rotational movement of the rotary member into a reciprocal movement of the slider in the longitudinal direction. A second motion conversion mechanism is operable to convert the rotational movement of the rotary member into a reciprocal pivotal movement of the slider in the vertical direction. The second motion conversion mechanism includes an arm having one end vertically pivotally connected to the slider. An actuating member is rotatable with the rotary member and has an abutting surface on which the other end of the arm slidably abuts. The abutting position of the other end of the arm on the abutting surface is varied as the actuating member is rotated, so that the vertical position of one end of the arm is varied.

Abstract: Apparatus comprising a striking piston driven hydraulically in a reciprocating fashion by an incompressible fluid inside a cylinder and striking against a tool, of the type in which the piston slides in a cylinder having two concentric piston bearing surfaces of different sections, of which that situated on the tool side has a section smaller than that remote from the tool, the piston and the cylinder delimiting two antagonistic chambers, an annular bottom chamber and a top chamber of larger section.According to the invention the interior of the top chamber is permanently at a regulated pressure of a value intermediate between the inlet or high pressure and the outlet or low pressure, and the annular bottom chamber is connected alternately by a distributor to the high pressure supply circuit during the upward phase of the piston and to the top chamber during the accelerated downward phase of the piston.

Abstract: A dough-processing system for dividing a dough sheet into multiple separate portions and transporting each portion in a predetermined direction. A rotary cutter, having a multiplicity of cutting dies affixed thereon, divides the dough sheet. The cutting dies have an exterior peripheral cutting edge for cutting the linear dough sheet into two or more linear portions for further processing on standard conveyor systems and an interior peripheral cutting edge for cutting an interior portion from the snack-piece dough. The rotary cutter includes an internal helical auger rigidly affixed to an external cylindrical mandrill having first and second ends and having a multiplicity of cutting dies affixed thereon. The rotary cutter has an ever-increasing diameter funnel path for transporting the interior cut portion of the snack-piece dough into the interior of the rotary cutter and thereupon the helical auger transports it out to the side of the rotary cutter.

Abstract: A paper punch having a pair of pivotably mounted top struts and a pair of pivotably mounted bottom struts, with the pair of top struts being pivotably mounted to the pair of bottom struts. As mounted, the pairs of struts can fold against each other. Associated with each adjacent top and bottom strut is a die which moves through guide openings when the struts are moved into their operative position away from each other. A spring is situated between each adjacent top and bottom strut for biasing each adjacent top and bottom strut away from each other as the pairs of struts are moved in a direction opposite to their folding direction. One of the pairs of struts define slits for the reception of a paper sheet to be punched.

Abstract: A hamburger patty knife is provided which comprises a handle and a transition piece at one end of the handle forming an angle with the longitudinal axis of the handle. A flat plate extends away from the transition piece in a forward longitudinal direction. A blade attachment is provided having a beveled front edge.

The television is held in place on the support member by a series of fasteners and is held in such a manner such that the television may not be readily removed from the support tray.

Abstract: An infeed system for a gang saw includes at least one loading station laterally displaced from the infeed station of the gang saw, a pivotable skewing tube arrangement operable at the loading station for orienting a two-sided cant to a given orientation relative to a line parallel with the longitudinal horizontal infeed line of the gang saw, thereby to obtain maximum yield from the cant, a lateral transport device operable to transport the skewing tube and the cant from the loading station to a position adjacent the infeed line while maintaining the cant in the desired orientation, and a longitudinal transport device for transporting the properly orientated cant to the gang saw. Preferably, a second loading station is laterally spaced on the opposite side of the infeed line from the first loading station, whereby cants may be selectively supplied to the in-feed station from the large-log and small-log sides of the mill, thus producing maximum production from a single gang saw means.
