A method is used to manufacture a lower jaw of an end effector of a surgical instrument. The method includes providing a lower jaw that includes a U-shaped body portion. The U-shaped body portion includes a bottom wall interposed between first and second opposing side walls. The method also includes forming at least one feature into at least one of the first and second side walls, wherein the at least one feature has a near net shape. The method also includes subsequently machining the at least one feature to have a machined shape.

The present invention provides a method of manufacturing a prefilled drug delivery device comprising the steps of arranging a piston rod member (20, 22, 120, 122) and a piston rod guide (40, 140) in a housing (10, 110) such that the piston rod member extends through a guide structure (13, 113) fixed in the housing and is surrounded by and operatively coupled with the piston rod guide, whereby rotation of the piston rod guide in a first direction relative to the housing causes distal movement of the piston rod member relative to the guide structure, and vice versa, and rotation of the piston rod guide in a second direction relative to the housing causes proximal movement of the piston rod member relative to the guide structure, and vice versa, and the piston rod guide is in a first state being capable of bi-directional rotation with respect to the housing, bringing a displaceable wall (62, 162) of a variable volume drug reservoir (60, 160) into abutment with a distal end portion of the piston rod member, moving the variable volume drug reservoir proximally relative to the housing to a completely mounted position, and shifting the piston rod guide irreversibly to a second state in which rotation of the piston rod guide in the second direction relative to the housing is prevented.

In a wrinkling prevention device, a work roll having a diameter smaller than that of a press-roll is pressed against the press-roll, and the work roll is supported by a bearing frame through a backup. With this configuration, an uncoated part can be elongated with a uniform pressing force. Further, an edge roller is disposed at an end part of the bearing frame which supports the work roll, and the edge roller is brought into contact with the other press-rolls not in contact with the work roll so that the axis parallelism of the work roll with the press-roll can be ensured.

A sludge digester including a vessel and floating cover. The vessel includes a sidewall and an interior volume configured to receive and contain sludge. According to one embodiment, the cover comprises a frame structure that is constructed and arranged to form a skirt member formed at a periphery of the cover and extending downwardly into the vessel, and a continuous ballast ring attached to a lower portion of the skirt member and configured to form a trough member with an interior surface of the skirt member. The sludge digester may also include a guide system coupled to the sidewall and the skirt member and configured to allow vertical displacement of the cover with change in volume of at least one of a gas and a sludge contained in the vessel beneath the cover.

A machine can form a work piece into a bowl subcomponent of a steel pan musical instrument. The machine includes a pressure lid and a die mold. The die mold may be formed of non-metal layers stacked between metal layers. In example operation, a blank or work piece is inserted between the lid and die mold. The lid is pressed down (e.g., by a hydraulic ram), forcing a portion of the blank into a face groove of the die mold for sealing. Pressurized water or other fluid introduced between the lid and the blank exerts pressure on the sealed portion of the blank and stretches the blank to conform to a bowl shape of the die mold. Note regions can be introduced by this machine-performed shaping and/or by subsequent manual operations to further prepare the work piece for incorporation into a steel pan musical instrument.

A method of manufacturing a cylindrical housing of an exhaust-gas treatment unit for vehicles includes providing a flat sheet metal part having at least one embossing, and round bending the sheet-metal part in a round bending tool by displacing the sheet metal part between rolls such that the sheet metal part obtains a cylindrical shape having a longitudinal direction parallel to roll axes of the rolls. At least one elastic roll is used such that the embossing of the sheet metal part is maintained during round bending. The longitudinal edges of the cylindrical sheet metal part are then connected to form a tube. A method of manufacturing an exhaust-gas treatment unit is furthermore shown.
