Abstract: The new invention is a portable tool, specifically directed electric motor driven nail gun. It has a nail push system, also a motor. The motor uses a flywheel as a speed reduction mechanism, the main characteristic is that the drive unit of the driving mechanism is connected to a pitman by a pin axis on one end, and the other end is connected to the pin axis which does the arc movement. The end of the drive unit props up the long slot by a spring and enclosed by the long slot in a sliding movement. The rectilinear reciprocating drive unit is governed by a clutching mechanism mounted on the speed reduction mechanism. The new invention can provide a powerful impacting force. The clutch bar of the driving mechanism has an outer bulge and inner bulge, it controls the tension spring which makes the drive unit impact nails and recover after impacting nails, without any memory of the rotating state.

Abstract: A stopper and container body are molded in the same molding machine. An assembly device, such as a pick and place robot, transfers the stopper from one mold cavity into the opening in the container body located within another mold cavity, or vice versa, to assemble the stopper and container body. Then, the assembled container body and stopper are removed from the molding machine and transported to a needle filling and laser resealing station for filling and laser resealing. A laminar flow source directs a substantially laminar flow of air or sterile gas over the mold surfaces, stoppers and container bodies, and assembly device, to prevent contamination during assembly.

Abstract: A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack. The instrument further has a manually actuatable retraction system that does not require the use of additional springs or other mechanisms to generate retraction forces which must be overcome when generating the forces necessary to fire the device. In various embodiments, the retraction system provides a visual indication to the surgeon as to how far firing has progressed.

Abstract: A weight plate having a detachable locking cartridge by which the weight plate is releasably connected to a lifting element (e.g., a center post) whereby one or more weight plates carried by the lifting element may be lifted by a user. The weight plate also has a plate body with a central bore in which to receive the lifting element. In one embodiment, the detachable locking cartridge is mounted flush against one side (e.g., the bottom) of the weight plate body so as to lie entirely external to the plate body. In an alternate embodiment, the detachable locking cartridge includes a stabilizer extension that is received within a cavity recessed in the one side of the plate body. The detachable locking cartridge includes a manually-accessible toggle lever switch arm that is adapted to rotate within a housing of the cartridge between locked and unlocked positions to thereby control the displacement of a locking pin relative to the lifting element within the central bore of the plate body.

Abstract: A side sealing apparatus for a shrink packaging machine comprising closed loop temperature control of a heater for maintaining an optimum temperature for cutting and sealing two layers of thermoplastic film. The heater comprises a cable or cartridge heater with an internal thermocouple, and it is connected to an automatic temperature controller. The heater is mounted on the side sealer apparatus between two sets of top and bottom V-belts mounted around drive rolls and idler rolls. The V-belts provide nip pressure against the film in order to drive the film. Nip pressure is generated by nip rolls on the scrap side of the film, and by belt support plates on the package side of the film.
