IPC: G03G15/08
Filed: 1982-08-19
Abstract: In the case of a copier which has a stationary, non-magnetic, cylindrical casing (2) and a magnetic roller (3) which rotates therein, magnetic toner (5) is supplied from the lower outlet end (6) of a container (4), via the non-magnetic surface (which runs tangentially with respect to the casing (2)) of a guide plate (7), in to the vicinity of the casing surface. The toner (5) is at this point transported via the casing surface to a development region. That end section of the guide plate (7) which is adjacent to the casing surface forms a first gap (d2). A wiper blade (8) is provided on the rear side of the guide plate (7) in the transportation direction of the toner (5). This wiper blade (8) is directed essentially at right angles to the casing surface and forms a second or wiper gap (d1) therewith. Toner accumulations are formed on the surface of the guide plate (7) and in the space between the guide plate (7) and the wiper blade (8), which toner accumulations ensure, if the two gaps (d1 and d2) are suitably dimensioned, that the toner is supplied in a stable manner, without leading to "flooding" on the casing surface or in the development region, and without having to place stringent requirements on the adjustment of the first gap (d2) which is formed by the guide plate (7). <IMAGE>

IPC: G11B5/024
Filed: 1983-04-09
Abstract: A data-erasing apparatus for magnetic tapes, in particular computer tapes, which have a magnetic label-record marking in the starting region is described. The data-erasing apparatus has a device for receiving and turning the magnetic coil to be erased, and an electromagnet, the magnetic field of which acts at least on a sector region of the magnetic coil for data erasure. Also provided is an empty reel which is provided with its own drive and to which the magnetic tape can be fed via a deflecting device. Arranged between magnetic coil and empty reel are a device for reading the end of the label record and a further electromagnet, designed as an erasing magnet. The erasing operation is performed during forward running and begins by switching on both the electromagnets when the reading device detects the end of the label record during winding of the beginning of the tape onto the empty reel. The erasing operation is performed during forward running, that is the winding of the beginning of the tape onto the empty reel, and lasts for as long as it takes for both the magnetic tape reel to perform a further revolution and for the region of tape located between the magnetic-tape reel and the further electromagnet at the beginning of the erasing operation to pass by the further electromagnet. Subsequently, the drive of the magnetic-tape reel is switched to reverse running.

Patent DE-3332965-A1 (DE)
Title: Solid-state dosimeter
Inventor: PIESCH ERNST
IPC: G01T1/11
Filed: 1983-09-13
Abstract: The invention relates to a solid-state dosimeter for measuring gamma radiation, consisting of an energy-dependent solid-state detector of prismatic construction and a perforated filter combination. The invention particularly relates to an energy compensation filter for TLD, RPS or TSEE solid-state detectors for adapting the response characteristics (measurement value/measurement variable), which is dependent on the gamma radiation energy, to the measurement variables of interest in radiation protection. It is characterised by the fact that the filter combination consists of two identical half sections which are held on two mutually opposite side faces of the solid-state detector, and in that each half section is composed of two metal strips extending at a distance from one another and a strip of material extending in the slot between the metal strips and absorbing little or almost no gamma radiation. The special advantages of the filter combination used in accordance with the invention consist in that the UV light excitation can occur perpendicularly to the longitudinal extent of the filter arrangement. Similarly, a UV beam can be used for exciting fluorescence, which excites the solid-state detector only in a predetermined part area, for example 1/10 to 9/10 of the solid-state volume, through the narrow side. The analysis is advantageously also carried out in parallel to the extent of the filter combination, the UV light being masked out, so that measurement is possible in the solid-state detector (glass) areas. ...

Title: Process for retreading vehicle tyres and for reinforcing the tyre by means of intermediate plies
Inventor: SCHMERMBECK DIETER
IPC: B29D30/52
Filed: 1983-09-16
Abstract: In a process for retreading vehicle tyres and for reinforcing the retreaded tyre by means of intermediate plies, stiffening intermediate plies are introduced in the shoulder region of the tyre carcass by fixing a prefabricated rubber tread strip to the carcass, into the lower layer of which the stiffening intermediate plies are anchored as early as during the production of the rubber tread strip. The rubber tread strip is bonded in a conventional manner to the carcass by a bonding rubber layer applied to this as an adhesion promoter, which bonding rubber layer is vulcanised at low temperature and pressure in a pressurised chamber. The belt-shaped or strip-shaped intermediate plies, for example made of steel or textile belt material coated with unvulcanised rubber, are applied to the top side of the rubber filling of the compression mould in a flat press during the production of the rubber tread strip and firmly anchored in the lower layer of the rubber tread strip by the pressure and heat treatment in the press. The carcass retreaded with such a rubber tread strip thereby obtains a substantial reinforcement and stiffening in the shoulder region for the purpose of reducing the rolling resistance.

Title: Circuit arrangement for a device with a program-controlled process-control circuit
Inventor: ALTENDORFER ALOIS
IPC: G05B19/042
Filed: 1984-03-30
Abstract: The AC mains voltage (Uw) is monitored. The required DC supply voltages (U1, U2) are derived from this via corresponding rectifier circuits (GA1, GA2). Two timers (R1, R2, C1 or R3, R4, C2) are provided, the first of which generates a reset potential for the process-control circuit (microprocessor) in the event of an interruption of the AC mains voltage if this interruption lasts longer than the time span which can be pre-defined with the timer. The second timer is activated when the voltage is restored and generates output information after a pre-defined time span with which the process-control circuit is released. It thus begins to execute the pre-defined programs with the start-up address taken in on the basis of the reset potential. If the device represents a small dial-up PBX system, the generated reset signal and its de-activation are able to ensure, for example, that no relays are erroneously activated in the event of mains voltage activation, failure or restoration. This is important if a so-called door-opener relay (T1) is present. <IMAGE>
