Filed: 1986-02-28
Abstract: The electronic door lock for an electronic key provided with an electronic store for a key word datum has a latch bolt (5) actuatable at least from the inside of the door by means of a handle and a bolt (7) which is lockable and unlockable by an electric drive device (35). A control circuit (81) formed especially as micro-processor reads the key word datum stored in the key, through the reading device (77), and controls the electric drive (35) in dependence thereon. The reading device (77) includes sensor elements (93, 95), especially pieco-electric elements by way of which the drive direction of the electric drive (35) is selectable by a key movement of short stroke. In order that the electronic lock may be opened manually in case of emergency, a mechanical lock cylinder (113) is provided by means of which the bolt (7) is uncoupled from the drive connection to the electric drive (35) and is bringable into a drive connection to the handle nut (23) actuating the latch bolt (5 ). Then by actuation of the door handle, in addition to the latch bolt (5) the bolt (7) can be unlocked. The data transmission between the reading device (77) and the electronic key takes place contactlessly by infra-red, like the working voltage supply of the key. The working voltage supply can however also take place through electric contacts.

Patent DE-3621495-A1 (DE)
Title: Device for synchronising two movements
Inventor: LINNARTZ LUTZ
IPC: H02P5/51
Filed: 1986-06-27
Abstract: For synchronising the movement of an audiotape (12) with that of a film (10), both movements are resolved into pulses. The pulses are fed to the upward input (Eu) or the downward input (Ed) of an upward/downward counter (26), the counter reading of which is at "000..." when the state of synchronisation is maintained. The most significant bit ("128") of the counter (26) is used to distinguish between positive and negative counter readings. In the case of positive counter readings, the correctively controlled drive is accelerated and, in the case of negative counter readings it is decelerated. To avoid simultaneously occuring pulses at the signal transmitters (11, 13) giving a reading which cannot be evaluated, flip-flops (FF1, FF2) are provided, which are sensed alternately. <IMAGE>

Title: Process for recovering boric-acid solutions that can be re-used in nuclear power stations from radioactive wastes and solutions arising in nuclear power stations
Inventor: BORNEMISSZA ENDRE
IPC: G21F9/00
Filed: 1986-10-07
Abstract: The invention concerns a process for recovering boric-acid solution that can be re-used in nuclear power stations from radioactively polluted technological solutions, liquid wastes, segregation waters or mixtures thereof, arising in nuclear power stations. In the process according to this invention, the solution (freed of suspended matter if necessary) is treated in a reverse-osmosis device, whose membrane retains at least 80% of the salts of the radioactive alkali and heavy-metal ions, but only has at most 30% salt retention for boric acid. Of the two solutions arising from this osmosis, namely the concentrate containing the majority of the radioactive substances and the permeate containing the majority of the boric acid and some alkali nitrate, the permeate is treated further in a reverse-osmosis device, whose membrane retains at least 90% of the alkali nitrates, but at most 40% of the boric acid. The concentrate arising in this stage is returned to the first reverse-osmosis stage, while the permeate is fed into a series of columns comprising at least two vessels connected in series and filled with macroporous, strongly alkaline ion-exchange resin in order to remove the residual content of alkali nitrate. The purified boric-acid solution, containing less than 0.001% by weight of alkali nitrate, is returned to the power station's boric-acid treatment system, and the concentrate is ...

Patent DE-3642480-A1 (DE)
Title: Method for generating high-voltage squarewave pulses
Inventor: NIEMEYER LUTZ DR
IPC: H01T2/02
Filed: 1986-12-12
Abstract: The generator (1) contains, connected in series, a high-voltage source (capacitor 4), a spark gap (5) and a load resistor (6) and a switching point in parallel with the load resistor (6). This switching point shortcircuits the load resistor (6) after a time delay determining the pulse width ( DELTA t) of the high-voltage squarewave pulses. This generator (1) is intended to supply high-voltage squarewave pulses with steep edge slopes whilst being of simple structure. This is achieved by the fact that the switching point is a creeping-spark gap (7). This creeping-spark gap (7) is dimensioned in such a manner that the transit time of a leader channel advancing in the creeping-spark gap (7) after the closing of the switching spark gap (5) is equal to the pulse width ( DELTA t). <IMAGE>

Title: Process for producing insulating material for high-temperature use
Inventor: KUMMERMEHR HANS
IPC: D04H1/66
Filed: 1987-04-22
Abstract: In the high-temperature use of inorganic insulating materials with organic additives as binder, treatment or the like, on initial use there is an odour nuisance due to gases which are produced in the decomposition of the organic additives. This can be avoided if the insulating material is subjected to a heat effect before its use, which leads to a decomposition of those organic additives which would have been subject to decomposition in service. For example, the hot side, in high-temperature use, of a mineral fibre web can be flame-treated to cause a decomposition of the binder down to a desired surface depth. In the case of slabs of microporous press-mould material with a covering containing organic additives, for example sized glass fibre fabric, at least the fabric of the hot side of the slab can be subjected to a corresponding heat effect before or after its completion to decompose the organic sizes. If required, an inorganic size can subsequently be applied to restore any desired properties for further processing. The essential feature is that all process steps in association with avoiding subsequent odour nuisance do not disadvantageously have to be incorporated into the proven production technologies. <IMAGE>
