Patent DE-4304151-A1 (DE)
Title: Apparatus for open-end rotor spinning
Inventor: STAHLECKER GERD
IPC: D01H4/10
Filed: 1993-02-12
Abstract: In an apparatus for open-end rotor spinning, with a spinning rotor which has a fibre-collecting groove and a fibre-sliding surface, the fibre-sliding surface is provided with a structuring which, as seen in the direction of the fibre-collecting groove, is opposite to the direction of rotation of the spinning rotor. The mouth of a fibre-feed channel is directed with a component in the direction of rotation of the spinning rotor towards the structured region. The structuring intersecting the fibres as a result of their arrangement exerts a conveying effect on the fibres in the direction of the fibre-collecting groove. The sliding of the fibres into the fibre-collecting groove therefore no longer takes place solely as a result of centrifugal force, and therefore construction no longer demands the hitherto conventional conicity of the fibre-sliding surface.

A comparison of the two averages is used to assess the slope of the standing vehicle. If this exceeds a critical value, the stored average is utilised for a predetermined time after the restart. USE/ADVANTAGE - Indicating amount of fuel left in tank. Precise measurement of fuel level.

Title: Process medium treatment for water extn. - by heating batch in concn. evaporator to evaporate water for condensing, eliminates toxic matter in vapour
Inventor: BRITZE RICHARD
IPC: C02F1/04
Filed: 1993-05-14
Abstract: Treatment comprises heating medium to an evapn. temp. below the b.pt. of water after movement in batches to a concn. evaporator (1). A jet system (6) over the medium (4) level (5) sprays the medium feed. The evaporated water is passed to a condenser (8) with a catch vessel (9) for the water outlet (17). When the water flow through the outlet (17) falls below a given vol., the jet (6) feed is interrupted and the treated medium is taken from the concentrator (1). A further jet system (7) in the concentrator (1) sprays the medium over the medium (4) level (5). The concentrator (1) has an initial zone (2) where the medium is held and heated in a batch (4). A 2nd zone (3) contains a condenser (8) and a catch container (9). The two zones (2,3) have a flow connection (10) between them, for evaporated water, above the level (5) of the medium (4). A level monitor (14) in the 1st section (2) activates the heating (14) when the medium is at a given level in the section (2). A flow vol. meter (18) is at the water outlet side which, in one setting, stops the flow of medium to be treated and, in a 2nd and lower setting, stops the jet (6) feed and also generates a signal for the medium to be removed. A heat exchanger (13) is in the flow path of the evaporated water from the medium for preheating. USE/ADVANTAGE - Used for the treatment of a process medium, which contains water in an emulsion. The water is extracted effectively from the medium, without carrying any toxic matter in the vapour.

Abstract: In a method for producing film capacitors, first of all a plurality of mother capacitors (3) are wound onto a drum (1), separating (isolating) layers (4) made of plastic films also being wound in between the mother capacitors (3). The ends of the separating layers (4) project over the output winding (2) formed in this way. Prior to separating the individual mother capacitors (3) along the separating layers (4), the projecting regions of the separating layers (4) are brushed off by a pot-type brush (6) having wire bristles (8). The peripheral region (5) of the drum (1) is matched to the width of the output winding (2), with the result that the bristles (8) of the pot-type brush (6) run virtually perpendicularly with respect to the projecting parts of the separating layers (4). <IMAGE>
