Title: Channel type section conveyor belt with corrugated sidewalls - has troughs of corrugations sloping upwards to corrugated top edges and lying between stiffening sides which form hollow spaces outside
Inventor: HARTMANN KARL
IPC: B65G15/44
Filed: 1992-06-25
Abstract: A rubber or similar conveyor belt has corrugated walls and a type of cross-section, whose conveying side troughs in the corrugations are at least partly filled with an elastic material. The troughs on that conveying side slope and taper upwards from the inner crests to the corrugated tops of the sidewalls and they have an expandable release area, as the elastic trough filling material forms hollow spaces open on the outer side. At least two sides of corrugations each contain a hollow space, beside stiffening the sidewall. The example shown has the rubber side (3) inclined at an angle where it carries the material conveyed. It is elastic and has the crests (2) in its corrugations; these (2) are anchored into the bases of the sidewalls and their top edge forms the corrugations (KG). The oblique faces (3) taper off into the troughs (1) and they provide the flexible release surface for the material conveyed. The outer side (AS) of the walls forms the hollow spaces (H). ADVANTAGE - The design has good self-cleaning properties without loss of stability or service life in its sidewalls even when they have a heavy construction. It does not significantly use additional material over existing designs.

Title: Vibration isolating method or inductive static displacement measurement - electrically damping current in measuring coil using frequency which gives lossy damping of coil current, and using damping value to measure proximity of core to coil
Inventor: KOLLER ROMAN
IPC: G09B15/00
Filed: 1992-12-03
Abstract: An electromagnetic alternating field coil measurement device is damped by a core inductively influenced by the coil's electromagnetic field. A frequency is selected for the coil so that lossy damping of the coil current occurs in the core. The damping of the coil current is a measure of the static and/or dynamic proximity of the core to the coil. An oscillator circuit is used whose resonant frequency results from the parallel resonance of the alternating field coil and a capacitor's capacitance. USE/ADVANTAGE - For dynamic pick-up of minute displacements e.g. in vibrating string, rod or surface. Also for absolute length measurement of statically occuring displacements. Applications include hit indicator for musical instrument training appts. e.g. for glockenspiel, xylophone; noise reduction in oil or gas burners; compensating for noise of laser inscription appts. for sign writing; noise suppression of window panes. Increased measuring sensitivity using fewer components.

Title: Device for catching oil, petrol or the like
Inventor: LINGE THOMAS
IPC: F02B3/06
Filed: 1993-08-04
Abstract: The invention relates to a device for catching dripping fluids, such as oil, and also fluids which are oily, contain oil or are obtained from oil, in particular petroleum, e.g. petrol or diesel fuel or lubricants, which device is in the form of a thin sheet of paper material which absorbs the fluid and the rear side of which is sealed to prevent fluid from coming through. The paper according to the invention is spread out in such a manner on underlying areas to be protected from oil that the non-sealed side of the paper points upwards and the sealed rear side points towards an underlying surface to be protected, e.g. a garage floor. This achieves the result that the paper absorbs and stores e.g. oil dripping down, without the absorbed oil coming through.
