Title: Cross-connection coupler for optical waveguides
Inventor: HOLBE ERHARD DIPL ING
IPC: G02B6/44
Filed: 1987-12-22
Abstract: Receiving panels (2) which are arranged in a rack and can be rotated about vertical longitudinal side axes (1) exhibit a multiplicity of optical coupling devices (3), which are arranged next to one another and above one another row by row and column by column, for optical waveguides. The ends of the optical waveguides (4, 6) coming from a central exchange or leading to the subscribers are connected to these coupling devices. Separate optical waveguides (7) which interact with the coupling devices (3) on the rack via connectors at the end are provided for optionally connecting these optical waveguides (4, 6). Both the optical waveguides coming from the exchange and those leading to the subscribers and the separate optical waveguides (4, 6, 7) are run close to the axes of rotation of the individual receiving panels in the rack and allow the receiving panels to be rotated open. This creates the necessary space for running and connecting the optical waveguides and the separate optical waveguides between the receiving panels which are normally close together. <IMAGE>

Patent DE-3800950-A1 (DE)
Title: Electrical circuit
Inventor: JUNKER WERNER
IPC: H05B39/04
Filed: 1988-01-15
Abstract: An electrical circuit is described for optional operation of a load at a higher supply voltage than is intrinsically permissible. The circuit is distinguished by the fact that the load is connected to voltage by an amplifier which is permanently connected through when the lower permissible supply voltage is applied, and furthermore in that the circuit contains an electronic voltage sensor which switches on a pulse generator when a higher voltage is applied, which pulse generator, for its part, switches the amplifier on and off intermittently so that only voltage or current pulses pass from the amplifier to the load which are added together at the load to form a root-mean-square voltage whose magnitude is equal to that of the maximum permissible operating voltage.

Title: Process for the production of a soya bean infusion and a soya cellulose, and use thereof
IPC: A23L11/00
Filed: 1988-01-15
Abstract: Processes for the production of an aqueous soya bean infusion and soya cellulose yield products which can be used for further processing to give soya bean food products such as whipped cream or mousses and frozen desserts. To produce the soya bean infusion, soya beans are dehulled, ground and mixed with water, the mixture is heated with steam and vacuum filtered and the resulting filtrate is deodorised. To produce the soya cellulose, the solid residue contained on vacuum filtration is softened in water, hydrolysed with hydrochloric acid, neutralised with sodium hydroxide solution and, after extracting the sodium chloride formed, the residue separated off is dried and chopped into particles. The food products obtained from the soya bean infusion and soya cellulose produced have improved properties and are free of the beany flavour which affects conventional soya bean food products.

Title: Vacuum switch having an external axial magnetic-field excitation device
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1988-07-07
Abstract: Axial magnetic-field excitation systems which, until now, have been composed of individual windings around the switch housing in a complicated manner are replaced by a considerably more simple and efficient system. The system consists of an integral cup (11, 12) in whose wall (10) webs (7) in the form of turns run between gaps (9) which are arranged obliquely with respect to the cup axis. Single (corresponding simple) electrical power supply leads can be connected coaxially (in a suitable manner) to this turn cup. One of these is, for example, by the likewise integral cup (8) which surrounds the turn cup and is connected to it at the end. Located in the base of this connecting cup is a central opening (16) which is extended in the form of a sleeve and surrounds the stationary electrical conductor bolt (5), with an insulating sleeve (17) being interposed. The electrical supply from the turn cup to the stationary electrical conductor bolt is effected by means of an extension (13) of the central opening in the cup base, which extension (13) is in the form of a sleeve and encloses said electrical conductor bolt such that direct electrical contact is made. The external diameter of the vacuum switch becomes even smaller if the turn cup is connected at the end directly to the correspondingly constructed switch housing wall, which now supplies current to the stationary switching contact (5, 6). <IMAGE>

Title: Device for mounting an electronic module on a base part
Inventor: ROHDE WOLFGANG
IPC: H05K7/14
Filed: 1988-09-07
Abstract: A device for mounting an electronic module on a base part is intended to be designed such that the module, on the one hand, makes reliable electrical contact with the mating contact in the base part and such that, on the other hand, good heat transfer is provided from the module to the base part. Furthermore, in the case of a base part for accommodating a plurality of modules, it is intended reliably to prevent a module being inserted at an incorrect point. To this end, the modules can be inserted under spring pressure into grooves in a base part which is constructed in the form of a frame, via flanges provided on said modules. The spring pressure is produced by leaf springs which are inserted into the grooves. The grooves and the tongues are shaped to match one another in such a manner that the modules can initially be checked for correct pairing with respect to the base part, without closing an electrical contact. It is not possible to close the electrical contacts until it has been confirmed that the module is correctly paired in the base part.

Patent DE-3833164-A1 (DE)
Inventor: MA JOHN Y
IPC: H03J1/00
Filed: 1988-09-27
Abstract: An audio tuning system includes a mixer 22 having inputs from an IF signal 19 containing audio sub-carriers and from an audio VCO20, the output from the mixer is fed to an audio detector 23 including an AFC detector 28 which provides an AFC error signal to control the VCO20. An audio seek signal 32, 33 controls the VCO20 independent of the error signal to start searching for an audio signal and when a new audio signal producing the desired IF is obtained the searching is stopped and AFC lock is then provided. The tuning system is used in a satellite receiver system which automatically locates audio signals among the various audio subcarriers received by an earth station; manual scanning of transmissions received from different transponders in order to locate audio signals embedded therein is eliminated. The receiver system does not require any input data characterizing the frequencies or bandwidth of the incoming audio signals and locates desired audio subcarriers in response to a command signal, without need for any manual intervention after generation of the command signal. <IMAGE>

Title: Process for closing off gaseous-media-channelling pipes
Inventor: BIEDERBICK MANFRED
IPC: F16L55/103
Filed: 1989-03-18
Abstract: Liquid-channelling pipelines can be closed off in that, in the pipes, a pressure-resistant ice plug is formed from the liquid by means of a externally active cryogenic coolant. In particular repairs on pipelines with missing or damaged fittings are thereby facilitated. In order also to be able to carry out this closure operation in the case of gaseous-media-channelling pipes, a gas/liquid mixture, for example a mixture of nitrogen and water, is sprayed into that region of the pipe (1) which is acted upon by the cryogenic coolant. For this purpose, use is made of a tapping connection stud (2) which is fastened in a gas-tight manner on the pipe and has shut-off devices (4, 5, 6) and a spray tube (8). The sprayed-in liquid freezes and forms the desired ice plug. <IMAGE>

Patent DE-3920696-A1 (DE)
Inventor: WELLER HUGO
IPC: G06F1/24
Filed: 1989-06-24
Abstract: The invention concerns a microprocessor with a watchdog circuit which monitors the correct progress of the processor programme. The watchdog circuit must be addressed at given time intervals by the microprocessor since it will otherwise execute an operation such as resetting the microprocessor to the beginning of the programme. In order to symplify the design, it is proposed that, when an error function recognized by the microprocessor (2) occurs, the microprocessor (2) addresses a specific error command to the watchdog circuit (5) which triggers the initiation of a reset function by the watchdog circuit (5).

Title: Continuous sepg. liq. from phthalic acid anhydride mfr. - by regenerative heat exchanger whose channels resist capillary clogging
Inventor: KRAUSE HELMUT DIPL ING
IPC: C07C51/573
Filed: 1989-07-19
Abstract: Liq. is continuously sepd. from the reaction prod. entrained in hot carrier gas streams cooled below the triple point for the prod., esp. phthalic acid anhydride made by the catalytically-aided gaseous oxidn. of naphthalene. Cooling is by a regenerative heat exchange whose heat storage structure provides defined channel widths in the flow direction, thus avoiding excessively conducted flow rates or liq. flow barriers. Using a counter flow principle, temp. at every point is the storage mass alternates between highest-lowest set values. Coolant for the storage mass is the oxidising air about to be used in the catalysed reaction. ADVANTAGE - Increased resistance to flow path clogging ensures minimising of retention of capillary adhesion of molten prod. more effectively than with switch condenser sepn..
