Patent DE-4104757-A1 (DE)
IPC: A61B1/313
Filed: 1991-02-15
Abstract: A device for inserting a laparoscopy or laparotomy instrument through a trocar tube (13) into a body cavity has an adjustment element arranged in a housing and shaped as a rotary drum capable of rotating around an axis that extends perpendicular to the longitudinal axis of a trocar tube (13) linked to the housing. Several radial through holes (24, 25, 26) having different diameters are formed in the rotary drum and can be selectively adjusted with respect to openings (8, 12) of the housing in order to ensure the tight passage of a trocar or other instrument. The drum (23) is rotatively mounted in a slide capable of moving transversely to the axis of the trocar tube. The slide has two opposite through holes (22) and sealing surface sections arranged on both of its sides that can be selectively aligned with the openings (8, 12) of the housing.
Patent DE-4107495-A1 (DE)
Inventor: EKSTROEM ERIK TOMMY
IPC: B65B63/02
Filed: 1991-03-08
Abstract: In a prior art method of filling containers such as paper bags, the material (13) to be introduced into the bags is first compacted in a compaction chamber (1). Compaction is carried out either by means of vibrators inserted in the material or by means of suction heads which, after each suction operation, must be blown free of material. The invention, on the other hand, calls for a vacuum to be applied above the level of the uncompacted material. This makes more rapid filling cycles and simpler equipment possible.
