Patent DE-3837312-A1 (DE)
Title: Winding apparatus for the winding of continuously arriving material webs
Inventor: HESSENBRUCH ROLF DIPL ING
IPC: B65H19/22
Filed: 1988-11-03
Abstract: In a known winding apparatus, the contact-roller unit is moved in steps relative to the stationary winding unit and, between the individual steps, the oscillating contact-roller suspension is pushed away from the winding shaft through the material package counter to a braking force. The oscillating movement of the contact roller acts on the light barrier which controls the stepping of the contact-roller unit. This leads to irregularities in the pressing force and therefore in the package density. The new arrangement is to have a simple construction and be variable and is to lead to a regular winding. The winding unit and contact-roller unit are movable relative to one another, the contact-roller unit is mounted fixedly and the winding unit is movable horizontally relative to the contact-roller unit. Coupling devices serve for coupling and fastening the winding unit to the frame of the contact-roller unit. The invention makes it possible to combine the fixed contact-roller unit with different winding units.

Title: Inductive identification system
Inventor: ZARRABI REZA DIPL ING
IPC: G06K7/08
Filed: 1989-01-24
Abstract: The inductive identification system (1) is used for the identification of goods carriers in conveying technology. For this purpose, identification carriers (8) in the form of a steel identification carrier are fastened onto the train set or the object carrier. When the identification carrier passes through the inductively acting sensor fork (16) of the identification system (1), the identification number of the identification carrier is detected without contact on the teeth (12) shortened in the binary code. By means of the subsequent microprocessor, the identification number is obtained from the sensor signals, and the identification carrier (8) and the sensors (2-3, 4-5, 6-7) are checked for a satisfactory condition before transmitting (relaying) the data. <IMAGE>

Title: Device for measuring surface resistance
Inventor: DUNZ THOMAS DR
IPC: G01R27/02
Filed: 1989-04-01
Abstract: The device for measuring the surface resistance of a voltage-loaded (stress-loaded) insulator (1) contains two electrodes (2, 3) which make contact with the insulator (1) on the surface. These electrodes (2, 3) are arranged substantially coaxially with respect to one another and delimit on the surface of the insulator (1) a measurement area exposed to a test voltage. In this measurement device, the intention is to prevent partial discharges across the electrodes (2, 3) as far as possible, even in the case of high test voltages. This is achieved by providing the electrodes (2, 3) in each case with a screening (4, 6) which relieves their contact points during testing with AC voltage from the effective electric field, and by making the electrodes (2, 3) in each case deformable in the region of their contact points. <IMAGE>
Patent DE-3918733-A1 (DE)
Inventor: HEIMBACH PAUL
IPC: F24D19/10
Filed: 1989-06-08
Abstract: A water heater comprises a store (2) which can be heated via a heat exchanger (1), and a tapping point (7) fed directly from this store (2) and/or from the heat exchanger (1). In the start-up phase of the tapping operation, the feeding is provided by the store (2), and as soon as the intended temperature at the outlet (11) of the heat exchanger (1) is reached, the tapping line (8) is directly fed by the heat exchanger (1) in the course of flow. In order to reduce the storage volume necessary to bridge the start-up phase, the water throughput is adjustable to a minimum value by means of a throttle (13) during the start-up phase, and a regulator (17) which monitors the initial temperature of the heat exchanger (1) does not open until the intended temperature level has been reached in a bypass line (10) bypassing the store (2) which then connects this outlet (11) of the heat exchanger (1) directly to the tapping line (8).
