Abstract: The invention concerns a hydraulic striking tool for application in rock and/or concrete cutting equipment containing a machine housing (100;200) with a cylinder (115;215) with a moveably mounted piston (145;245) which during operation performs a repetitive forward and backward movement relative to the machine housing (100;200) and directly or indirectly strike a rock and/or concrete cutting tool (155;255), and where the piston (145;245) includes a driving part (165;265) which separates a first (120;220) and a second (105;221) driving chamber formed between the piston (145;245) and the machine housing (100;200) and where these driving chambers are arranged to include a pressurized working fluid during operation. The total volume V of the first and second driving chambers is inversely proportional dimensioned to the square of a for the striking tool recommended maximal pressure p, as well as proportional, by a proportionality constant k within the interval 5.3-21.

Abstract: An endoscopic stapler comprises a first jaw and a second jaw. The first jaw includes structure for retaining a plurality of staples. The first jaw and second jaw are mounted to permit pivotal movement of the first and second jaws relative to one another. The endoscopic stapler also comprises at least one clamp member for clamping tissue and pulling the tissue into a position between the first jaw and the second jaw to facilitate inserting at least one staple of the plurality of staples into the tissue. A first handle is operably coupled with the first jaw such that movement of the first handle effects delivery of the at least one staple of the plurality of staples to the tissue. A second handle is operably coupled with the second jaw and the at least one clamp member such that movement of the second handle effects movement of the second jaw and movement of the at least one clamp member.

Abstract: A stretch wrapping machine structure contains: a rotary disc including a column on which a guide way is arranged; an abutting plate including a rotating stem and a pushing portion adjacent to the rotating stem; a hot pressing sheet including a cutter seat, a driven bar, and a press segment; a holder including a V-shaped cross section and formed in a plate shape, the holder also including an actuation member, an actuating post, an operating segment, and a third cylinder; a biasing rod including a driving peg and a push segment; a controlling unit secured on a predetermined position of one side of the column; an air blowing unit located at a predetermined position of the holder. Thereby, an object is held on the rotary disc and is packed by a plastic film quickly and easily.

Abstract: A portable machine tool switching unit includes a turning knob unit, which has a coupling unit that can be rotatably driven for coupling to at least one switching element, and further includes at least one energy storage element provided for storing switching energy in the case of a preselection. The energy storage element is integrated in the turning knob unit.

Abstract: A method and system for packaging products provides for initially, vertically stacking a plurality of products during production in a transfer canister, simultaneously removing a stack of the products from the transfer canister, reorienting the stack and horizontally loading the stack into a final product package cavity. The invention has applicability to a wide range of products, particularly food products, such as refrigerated dough products. In one embodiment of the invention, the product package cavity is thermoformed as part as an overall horizontal form, fill and seal system.

Abstract: A surgical stapling apparatus (stapler) is provided. The stapler includes a housing, elongated member, and a reload. A cartridge is configured to selectively couple to a first jaw member of the reload and includes one or more resilient members thereon. An anvil operably supported on a second jaw member of the reload is configured to compress one or more fasteners ejected from the cartridge. The anvil includes one or more locking members thereon. A knife is configured to translate through the cartridge and anvil when the first and second jaw members are in a closed configuration. Engagement between the knife and the resilient member(s) causes the resilient member(s) to move from an initial configuration that allows the knife to travel distally past the locking member(s) to a final configuration that allows the locking member(s) to engage the knife.

Abstract: According to some implementations a packaging operation is provided that includes a stage for the continuous feeding of a laminar film, a stage for the forming of the laminar film with a laminar tube being obtained, and a drive stage in which by means of at least two drive belts the movement of the laminar tube is caused. The packaging operation also includes a control operation in which the position of the drive belt in relation to the forming tool is controlled when slippage or risk of slippage of at least one of the drive belts with respect to the laminar tube is detected.

Abstract: A packaging bag line-folding and sealing machine includes a first sealing unit and a second sealing unit for sealing a packaging bag therebetween, a first rocker arm and a second rocker arm mounted at the first sealing unit, a locating block, a first link coupled between the first rocker arm and the locating block, two line-folding units, and two second links coupled between the second rocker arm and the line-folding units for moving the line-folding units to make folding lines on the packaging bag between the first and second sealing units upon movement of the first sealing unit relative to the locating block. The application of the packaging bag line-folding and sealing machine greatly improves the packaging quality of packaging bags, and allows adjustment of the line-folding units to fit different sizes of packaging bags, enhancing user convenience.

Abstract: An adapter for hands-free attachment of an installation clip to a commercially available power driving tool. The adapter has a frame and a magnetic element. The adapter is rigidly attachable to the nozzle of a power driving tool by mechanical forces, magnetic forces or a combination thereof. Once attached to the nozzle, the adapter allows attachment of an installation clip by magnetic forces generated by the magnetic element in a position for driving of an elongated securing member from the nozzle through an attachment hole in the clip. The force of the driven securing member overcomes the attractive magnetic forces and disengages the clip from the adapter.

Abstract: A surgical stapling device including an elongated body portion having a proximal end and a distal end, and defining a longitudinal axis therethrough is presented. The surgical stapling device further includes a handle assembly positionable adjacent the body portion at the proximal end thereof and an introducer assembly positioned at the distal end of the body portion. The introducer assembly includes a sleeve positionable over at least a portion of a shell, the sleeve having a slanted distal end configured to receive a slanted membrane thereon.

Abstract: The impacting tool has a tool holder and a locking part. The locking part can be driven to move between the bit holding position, where it is engaged with the tool bit inserted into the bit inserting hole so that pullout is restrained, and a bit holding released position where the engagement is released and pullout is allowed. The locking part and the tool holder can be integrated with each other while moving in the longitudinal direction of the tool bit, so that they can be driven to move between the bit anchored position where the locking part is set at the bit holding position and the engagement state with respect to the tool bit is maintained, and the bit last connection/disconnection allowed position where the locking part is set at the bit holding released position and releasing of the engagement with respect to the hammer bit is allowed.
