Abstract: The invention relates to a process and a device for laser beam cutting, the focal point of the laser beam lying within the nozzle channel of the cutting nozzle. The cutting nozzle has a shape which makes possible flow of the cutting gas in the form of a bunched jet, as far as possible parallel, preferably at supersonic speed, into the forming kerf in the workpiece being machined. In this extended design of the cutting nozzle, e.g. with a conical nozzle inlet and an otherwise cylindrical nozzle channel or with a cutting nozzle similar to a Laval nozzle, the nozzle channel is preferably mirrored. This can be achieved by polishing or coating the nozzle channel. Suitable cutting gases are oxygen of high purity, nitrogen, argon, helium, hydrogen and/or compressed air. The cutting nozzle can in addition be cooled.

Abstract: A block of amplitude modulated television channel signals frequency modulates an optical communication path. In one embodiment, the AM modulated channel signals FM modulate an RF subcarrier which, in turn, is used to intensity modulate an optical carrier for transmission. Frequency modulation of the RF subcarrier by the amplitude modulated channel signals is advantageously performed at microwave frequencies. The FM modulated subcarrier signal is then converted down to a frequency range compatible with transmitter and receiver components used in the system. The frequency modulation and conversion can be performed by a pair of voltage controlled oscillators coupled in a push-pull mode of operation. The outputs of the oscillators are combined in a double balanced mixer to down convert the FM signal spectrum. In another embodiment, the optical frequency of an optical carrier is FM modulated by the block of AM signals. Receivers for the FM modulated band of AM channel signals are also disclosed.

Abstract: The subject-matter of the invention is a trip device which leads to disconnection when the insulation resistance falls below a specific value. The main field of use is protection technology. The trip device is used especially for protection measures against electrocution in bath tubs, especially for installation in hair dryers. The idea of the invention consists of a symmetrically arranged series circuit of two fixed resistors (Ra, Rc) and two voltage-dependent resistors (Ga, Gc), which circuit is connected to the power source. The insulation resistance (Ris) which is to be monitored is connected via a probe (S) in the centre of the series circuit, which acts as a voltage divider. If the insulation resistance Ris falls below the permissable value (for example as a result of the influence of water), then a relay coil (Rs) which is connected in parallel with the fixed resistors (Ra, Rc) is energised and the relay contacts (Ka, Kc) disconnect the series circuit and hence also the connected load apparatus. Disconnection also takes place in the event of plug reversal, because of the balanced nature of the series circuit. <IMAGE>

Abstract: In an apparatus for optically processing data, an optical head (13) for applying a light beam on a rotating optical disk is moved along a radial direction of the optical disk and a light beam reflected from the optical disk is defeated by a photodetector having detecting regions. Detection signals from the detecting regions are added and substrated each other so that difference and sum signals are generated. The signals are converted into binary signals in binary circuit (17, 18) and the binary sum signal is corrected by a correction circuit (19). The corrected sum signal and the difference signal are compared by a direction detection circuit (20) so that a moving direction signal indicating a moving and is supplied to a pulse generator (22) direction of the optical head is generated from the detection circuit (20) and a pulse signal indicating a moving speed of the optical head (13) is generated from the pulse generator (22) and is counted by a counter (23).

Abstract: To accelerate the connection of the devices (separate loudspeaker, loudspeaker of the terminal) for the purpose of an announcement, the connection request is first simultaneously transmitted to a limited maximum number of associated devices by the computer control (Ast) on the basis of a group-individual identification number (KZ) to be entered. A counter (PZ) to be set to this number is reset on the basis of each arriving acknowledgement information (ZRS). Then, further connection requests (VA) are in each case sent out to the devices until this maximum predetermined number of call-ups has again been reached. With the acknowledgement signal of the last device (KE-D-Bg) of the group (GR), the operator is informed by a corresponding audible tone (TSg) that all free devices of the group have been effectively connected. <IMAGE>

Abstract: In this process for the addition of ferrocene to fuels or to petrols, improved metering of the ferrocene additive into the combustion chamber of an internal combustion engine or combustion installation is to be made possible. For this purpose, the sublimation properties of ferrocene are exploited by transferring the latter by means of sublimation into a stream of the combustion gas or a part stream thereof and feeding it together with the fuel or petrol present in fine distribution as solid or liquid particles or in the vaporised form to the chemical conversion by combustion. A preferred application is the charging of the combustion chamber of a diesel engine fitted with a diesel particle filter by means of a carrier gas stream enriched with ferrocene vapour in a sublimator.
