The anvil is operable to compress tissue against the deck surface.

Abstract: The present disclosure relates to an adapter assembly for electrically and mechanically interconnecting electromechanical surgical devices and surgical loading units. The adapter assembly includes an articulation assembly having a rotatable drive shaft having a proximal end rotatable by a surgical device and a distal end having a gear with external teeth, a gear nut including external gear teeth meshingly engaged with the external teeth of the gear, a screw disposed within the gear nut and including external threads engaged with internal threads of the gear nut such that the screw is axially moveable relative to the gear nut, and an articulation bar operably coupled to the screw such that axial movement of the screw results in corresponding axial movement of the articulation bar.

Abstract: A hydraulic hammer for a machine is provided. The hydraulic hammer includes a housing and a piston disposed within the housing and adapted to reciprocate along a longitudinal axis of the housing. The hydraulic hammer further includes a first chamber and a second chamber defined within the housing. The hydraulic hammer further includes a primary passage extending from an inlet and branching into a first passage and a second passage. The first passage fluidly communicates the primary passage with the first chamber and the second passage fluidly communicates the primary passage with the second chamber. The hydraulic hammer further includes a flow control device coupled to the first passage. The flow control device includes a valve element adapted to move between a first position and a second position based on an input signal indicative of a pressure of charge in the first chamber.

Abstract: The invention relates to a drive-in device, comprising a hand-held housing having a piston element received therein for transmitting energy onto a fastening element to be driven in, an exchangeable propellant charge, a combustion chamber, arranged between the propellant charge and the piston element and extending about a center axis (A), and a control element by means of which a starting position of the piston element can be set to be modified in order to modify the energy transmitted by the propellant charge onto the piston element, the control element having an operating element that can be pivoted about the center axis (A).

Abstract: A support device (20), mounted on an upper edge of a container (3), includes lifting elements that define a support surface (22) which extends transversely outwards from an inner edge (55). The upper end (2b) of a flexible pouch for biopharmaceutical product can rest on this support surface, the rest of the 3D-type pouch extending into the container. The slot (23) which separates the support surface into two portions defines a guide path for a flexible supply line (9a, 9b) for the pouch (2) that is connected at its bottom to the end (2b). A convex surface is formed at the rear end of the slot and above the edge of the container, so as to guide and facilitate the passage of the line (9a) into the housing, when the filling state is sufficiently advanced. The causes of poor deployment of the pouch are thus minimized, without human intervention.

Abstract: A wrapping device and a web supplying method are used on board of an agricultural harvester. A supply reel with wrapping material is held between two parts of an unrolling station. A web moving member moves a web taken from this supply reel away from the unrolling station. For replacing the supply reel with a further supply reel, the further supply reel is placed on at least one supporting roller. The or every supporting roller is stationary and is positioned angularly below the unrolling station and between two unrolling station parts. The further supply reel on the supporting roller is shifted in a shifting direction towards an unrolling station part.

Abstract: A hydraulic hammering device that uses a scheme in which a front chamber is switched into communication with a low-pressure circuit when a piston advances, wherein occurrences of “galling” to the piston at a sliding contact portion with a front-chamber liner is reduced. The front chamber has the front-chamber liner fitted to an inner surface of a cylinder. A hydraulic chamber space communicating with the front chamber and filled with hydraulic oil is formed as a cushion chamber on the inner peripheral surface of a rear portion of the front-chamber liner. The cushion chamber has a second drain circuit (from first end face grooves to slits to second end face grooves), which is provided separately from a drain circuit that guides the hydraulic fluid passing through a liner bearing of the front-chamber liner to the low-pressure circuit.

Abstract: A two-step auto stroke hydraulic breaker includes a cylinder including a high-low pressure chamber, a high pressure chamber, and a pressure converting chamber including a pilot port, a high pressure connecting port connected to the high pressure chamber, a sensing port, an oil tank port, a long stroke port, and a short stroke port, a piston including small diameter portions, upper and lower large diameter portions, a sensing fluid groove between the upper and lower large diameter portions, and a return fluid groove formed on the lower the large diameter portion, a fluid circuit unit to control a supply direction of the fluid to the cylinder and to generate a fluid pressure to selectively change a stroke, and a chisel to break the bedrock when a lower portion of the piston descends to impact the chisel during a descending operation.

Abstract: A plastic material wave bag assembly having a sheet-like first side panel and a sheet-like second side panel oriented in opposed congruent relationship to one another when in a folded condition. The wave bag assembly includes a single use closure adhesive strip disposed and oriented primarily laterally across an interior wall of the upper panel section of the first side panel at a location below the handle apertures. The closure adhesive strip is configured to selectively close and maintain the upper panel sections in a closed condition while the remaining portions of the first and second side panels are maintained in the receiving condition.

Abstract: The invention relates to a base mechanism and a roller mechanism of a floor nailing gun. The base mechanism includes a base fixedly connected to a bottom of a main body of a floor nailing gun. At least one adjustment roller assembly is movably disposed at a front end portion of the base, each adjustment roller assembly includes an adjustment roller having a lowest point in contact with a floor surface when in operation. The roller mechanism includes a base fixedly connected to a bottom of a main body of a floor nailing gun, at least one roller group is disposed at a rear end portion of the base, an elastic reset member is disposed between the roller group and the base, each roller group comprises a roller having a lowest point in contact with a floor surface when the roller is in a normal state.

Abstract: A package insert for cushioning an object during transport includes a plurality of support pins disposed in parallel with respect to each other, and a perforated sheet having a plurality of perforation holes disposed therein. Each of the plurality of supporting pins is disposed within a corresponding perforation hole of the plurality of perforation holes. Each of the plurality of perforation holes has a diameter or width that is equal to or smaller than a diameter or width of its corresponding supporting pin such that the corresponding supporting pin is kept in place by friction when inserted into the corresponding perforation hole.
