TL;DR: In this paper, a surgical stapler instrument is provided for applying lateral lines of staples to tissue while cutting the tissue between those staple lines, which includes a handle portion, an implement portion, a reciprocating section, a drive member and a movable actuator.
Abstract: A surgical stapler instrument is provided for applying lateral lines of staples to tissue while cutting the tissue between those staple lines. The instrument includes a handle portion, an implement portion, a reciprocating section, a drive member and a movable actuator. The implement portion includes a staple cartridge and an anvil. The reciprocating section is adapted to move back and forth along an axis of the implement portion. The movable actuator is associated with the handle portion and is engaged with the drive member such that motion of the actuator causes the drive member to move back and forth between first and second drive positions separated by a first distance. A multiplier is further provided and is associated with the reciprocating section and the drive member for causing the reciprocating section to move back and forth between first and second reciprocating positions in response to movement of the drive member. The reciprocating section includes a work portion which, when moved distally, effects the firing of staples in the staple cartridge toward the anvil. The work portion is also provided with a reciprocating knife. The first and second reciprocating positions are separated by a second distance which differs from the first distance.

TL;DR: In this article, the design and realization of two pumps based on micromachining of silicon are described, which are of the reciprocating displacement type, comprise one or two pump chambers, a thin glass pump membrane actuated by a piezoelectric disc and passive silicon check valves to direct the flow.

TL;DR: In this paper, a TIG torch is maintained at a fixed spacing from the surface of a camshaft while relatively reciprocating the torch and the cam shaft so the torch heats the surface along an undulating path, and the pitch or crest-to-crest spacing of this path is maintained constant for uniform hardening.
Abstract: A cam of a camshaft has its surface hardened by rotating the camshaft about its axis while maintaining a TIG torch at a fixed spacing from the surface, and while relatively axially reciprocating the torch and the camshaft so the torch heats the surface along an undulating path. The pitch or crest-to-crest spacing of this path is maintained constant for uniform hardening either by varying the angular rotation rate of the camshaft or by varying the axial reciprocation frequency between the camshaft and torch. The radial spacing of the portion of the surface being heated at a given instant from the axis is measured to control the rotation or reciprocation rate.

TL;DR: A new battery thermal management method using a reciprocating air flow for cylindrical Li-ion (LiMn 2 O 4 /C) cells was numerically analyzed using a two-dimensional computational fluid dynamics (CFD) model and a lumped-capacitance thermal model for battery cells and a flow network model.
