Title: Device for detecting the filling level of a capillary overflow channel
Inventor: ROSBERG RAINER DIPL ING
IPC: G01F23/26
Filed: 1993-02-27
Abstract: In channels of very small cross-section it is difficult to detect various filling levels, since the differential pressure available for the measuring process is very small. By means of the novel device, the filling level of a small, preferably capillary, overflow channel is intended to be measurable by means of a capacitive sensor. A channel (6) is connected in terms of fluid to an overflow channel (7). A capacitive sensor (91) is formed from an inner electrode (25) and an outer electrode (24), which are formed as essentially cylindrical bodies plugged into one another and which enclose the overflow channel (7) between them. The overflow channel (7) is configured in a screw shape. The device yields good measurement results for all liquids, including coloured ones. In this way it is possible to obtain a sufficiently large signal, which can be evaluated for example for a metering process, by means of a control device. Because of its closed construction, the device is protected from environmental influences. <IMAGE>

IPC: B62J19/00
Filed: 1993-03-31
Abstract: The invention proposes a box-like storage apparatus for two-wheelers, such as bicycles (10), mopeds or motorbikes, which is provided with a fixed roof element (14), which covers over the deposited two-wheeler in the form of a U transversely with respect to the longitudinal direction of said two-wheeler and which provides only partial roofing in the longitudinal direction, and with at least one further roof element (19, 20) which can be pivoted out of the said roof element (14) and is intended for covering an end region of a two-wheeler. All the roof elements (14, 19, 20) are designed in the form of a U with circle-segment-like side walls which form U-legs and essentially taper towards two pivot points (18) in the vicinity of the ground. That opening of the fixed roof element (14) which is directed away from the pivot-out roof element (19, 20) is provided with a cage-like continuation (27) which receives essentially a front wheel or rear wheel of the deposited two-wheeler. At least in the open state, a bicycle box of this type is of a very short structure and of low volume and, in a simple operation, a two-wheeler can be readily pushed in, secured and also removed again. In this arrangement, good protection against theft and weathering is achieved. <IMAGE>

Inventor: MOEDDER RALF DIPL ING
IPC: F16G5/20
Filed: 1993-05-20
Abstract: The belt body (10) of a V-belt or ribbed V-belt includes a longitudinal reinforcing inlet (14) embedded therein. In the longitudinal direction of the belt, this reinforcing inlet (14) has an elastic modulus of less than 3,000 N/mm but more than 1,500 N/mm.
