Patent DE-3832290-A1 (DE)
Title: Ski having a ski binding
Inventor: PLENK ANTON
IPC: A63C9/00
Filed: 1988-09-22
Abstract: The ski has a ski binding which with respect to its longitudinal axis is mounted non-symmetrically to the ski longitudinal axis of the sole. The position of the ski binding can be changed transversely to the ski longitudinal axis as a function of a pressure exerted on the ski binding. In this manner, the position of the ski binding is continuously matched to each ski step, transversely to the ski longitudinal axis, depending in each case on whether the ski binding has pressure exerted on it from the foot or from the ski boot. The eccentric displacement permits a larger force and hence also a greater pressure to be applied to the particular edge. The pressure is preferably determined by means of pressure sensors and the displacement of the ski binding in dependence thereon is calculated and/or controlled in an optimum manner in a microprocessor. The features and measures according to the invention can be used not only for cross-country skis but also for down-hill skis, mono skis, snowboards, ice skates etc.

Title: Boosting microwave effects on flowing material - by internal displacement with mechanical stirrer or bellow
Inventor: SCHULZE REINHARD
IPC: H05B6/80
Filed: 1989-09-12
Abstract: A charge of material (2) to be melted and/or dissolved by microwave action undergoes such action while in a container (1) inside an outer housing (3), e.g. with magnetions (5) at opposite side walls.

Title: Moulding crates with hollow handles - by injection moulding crate with solid handle, forming an outlet from cavity, and blowing out core of handle while still soft
Inventor: KOOSE RUDOLF
IPC: B29C45/17
Filed: 1989-12-05
Abstract: Hollow areas are produced in the walls of plastic boxes, and bottle crates in particular, the process being especially for making hollow handles on the crates concerned. In the first stage the walls or handles are made solid by injection moulding; an outlet is then made in the mould and the interior of the handle is blown out while it is still soft. The mould tools produce the handle for a crate, at the split line. The layout has a moving perforating rod; beneath this the cavity has an outlet space in the split line. The crate is injection moulded in the normal way, so that the handle is a solid component. After a short time a needle is brought into the interior of the handle and a blowing gas is injected through it while the perforating rod is withdrawn to the left, so freezing the outlet space. The blowing gas expels the interior of the handle out through the space. After a further period the handle has hardened enough to allow the finished crate to be demoulded. USE/ADVANTAGE - The method produces hollow handles with the desired cross-section but with uniformly thin walls, although they still have sealed surfaces. The handles are comfortable for the user.
