Patent DE-4430845-A1 (DE)
Title: Bicycle gearing with traction transfer element
Inventor: ALBERSINGER GEORG
IPC: B62M9/08
Filed: 1994-08-31
Abstract: A traction element (2) positively engages symmetrically arranged toothed discs (1) on a common longitudinal axis to transfer force between them. The gear discs have several staged pitch circles so the interval between the two discs increases as their dia. increases. Traction is pref. transferred by disc-engaging round bolts which are joined endlessly in their centre similar to a roller chain via a flexible tensile strand. The element is switched between gear diameters by altering the interval between the gear discs. The changes are assisted by a shallow ramping effect, the element bolts rotating smoothly within wear-resistant sleeves as plaited into an endless strand by heavy-duty fibres, followed by an endurably elastic casing material. The traction element can also be provided by a conventional roller chain, this however elastically encapsulated at the joins as proof against ambient effects and possible oil loss. The gear interval change can be effected by axial jockey cams and a roller bearing.

Title: Sepn. of organic vapour from air streams by permeation through a membrane
IPC: B01D53/22
Filed: 1994-10-22
Abstract: In a system for removing organic vapours from an air stream (A) by selective permeation through a membrane (m), the air is delivered to one side of the membrane by a compressor (V) and led away in cross-flow via a throttling device (D). A permeate stream is removed by a vacuum pump via a condenser (TK) and separator (KA), from which the organic component is removed as a condensate. The compressor and the vacuum pump are in the form of a jet ejector driven by the condensate as a propellant from a drive pump (P). The propellant stream is added to the air stream which enters via a throttle (ED). The outlet from the ejector is connected to the inlet to the separator, whose outlet is in turn connected to the inlet to the membrane chamber.

Patent WO-9628702-A1 (WO)
Inventor: JOSTEN HANS-J
IPC: F27D1/00
Filed: 1996-02-14
Abstract: In revolving hearth furnaces for annealing cylindrical or tubular materials (5), these materials are set into semicircular radial recesses that prevent them from rolling sideways. In time, wear causes these recesses to work themselves into the refractory material, so that the materials to be annealed sink down and the surface available for heating is reduced. As wearing down progresses, quality problems may result. In addition, the availability of known furnaces is reduced, since they must be repaired from time to time. To solve these problems, a moulding (3) is disclosed in which the semicircular recess (6) is shaped at the top of a bulge (7) whose cross-section tapers towards its top.
