Abstract: A metal plate is formed in a process comprising cutting, perforating or both, by forcing the plate, by means of an abrupt and intense force towards a mold having openings or boundaries defined by wall sections which extend essentially normal to the forming plane of the mold. Consequently, the plate is cut along the edges of the openings or boundaries. The force may be a pulsed magnetic force or may be a force generated as a result of the discharge of electric current through a fluid.

Abstract: A press product line of presses for massive forming has toggle lever transmissions for driving a slide. Different slide strokes and path-time characteristic curves of the slide movement are achieved starting with uniform blank components. The critical dimensions, i.e., the bearing locations of the toggle lever transmission on the machine frame, are constant within the entire press product line, so that at least to that extent, uniform machine frames can be used. Specially desired path-time progressions are achieved through appropriate fine machining of the blank components (eccentric, connecting rod and link bars).

Abstract: Calender and process of calendering a web in calender. The calender includes a frame, an upper roll, a lower roll, an intermediate roll arrangement that includes an intermediate roll that is fixed in the frame, and a load limiting device coupled to the intermediate roll. The process includes loading the intermediate roll in two directions in a pressing plane direction via the upper and lower rolls, monitoring pressures exerted in the two directions on the intermediate roll in the pressing plane direction, and releasing the load on the intermediate roll when a difference between the pressures exerted in the two directions on the intermediate roll is greater than a predefined amount.

Abstract: A first embodiment of a drive arrangement for a large rectangular baler includes hydraulic pump and motor sets, and second and third embodiments include only gear and shaft arrangements, for driving the plunger for compressing the crop being baled, and for driving all of the auxiliary functions. In all embodiments, power delivered by a main shaft is divided between an auxiliary function drive shaft and a plunger drive shaft. In the first and second embodiments, a flywheel is located for smoothing the power flow to the plunger drive arrangement, and in the third embodiment the flywheel is located for smoothing power flow to both the plunger drive arrangement and the auxiliary function drive arrangement. In all embodiments, the rotation of the shaft carrying the flywheel due to the inertia of the flywheel is ineffective for driving the plunger and auxiliary function drive arrangements when power to the main drive shaft is cut off.

Abstract: Tool units (400) are slid by crank mechanisms (409) which are arranged on the respective sides of a table (200), convert rotational motions into translational motions, and use servo motors as drive sources, and are supported to swing on the rear end portions of the tool units.

Abstract: The present invention contemplates a trash can that one finds in high-traffic public venues. The trash can receives trash through an opening in the top of the housing. A trash by-pass chute is disposed within the housing and transports the trash from the opening in the top to the lower portion of the housing. A mechanism for automatically compacting the trash in the lower portion of the housing is provided within the housing. The compacted trash may be removed from the lower portion of the housing via a door that opens to allow access through the side of the trash can. The mechanism for compacting trash contents includes a frame disposed within the housing, and a compacting mechanism carried by the frame. The compacting mechanism includes a platen and is configured for moving the platen through a compaction stroke to apply compacting pressure to trash contents located in the lower portion of the housing during at least a portion of a compaction stroke.
