Title: Communications system for internal company use - has interfaces to allow handling of various terminal types and methods of transmission
Inventor: RUEGER WOLFDIETER
IPC: H04Q3/48
Filed: 1978-10-06
Abstract: The internal communications system e.g. for electricity supply comprises includes telephone sets, teleprinter terminals, branch exchanges and interconnecting lines and handles different types of signal transmission, e.g. voice signals via wires or free space, carrier frequencies, d.c. and a.c. telegraphy. All terminals connected to one exchange have connecting units connected by a call device to the exchange's central control unit in the same way. These connecting units act as interfaces which supply binary signals representing the characteristic circuit states to the central unit and convert incoming selection information into binary coded data for the exchange.

Title: Two-zone activated sludge tank to purify waste water - offers high efficiency treatment by repeated inter-zone transfer for intermittent aeration
Inventor: AUSTIN ERIC PAUL
IPC: C02F3/30
Filed: 1978-12-28
Abstract: The tank is of the type in which the water is agitated by an aerator, e.g. a rotary impeller, The aerator is surrounded by a partition enclosing an inner zone of liq. and an annular outer zone of liq. is held between the partition and the outer wall of the tank. A passage is formed through the partition at or near surface level and another passage at or near tank base level. The aerator creates a flow of liq. through a passage from the inner zone to the outer zone. The transferred liq. circulates around the outer zone before finding its way back to the inner zone via a different passage. The passages are pref. formed and positioned and related to the direction of rotation of the aerator so that flow is outwards from the inner zone via upper passages and inwards from the outer zone via lower passages. The tank is pref. of vertical cylindrical form with a coaxial, vertical cylindrical partition around a central aerator. The treated effluent can be equal to that delivered from the conventional 3-stage process, i.e. free of ammonia and probably nitrates too. For such effective treatment the new plant is very compact and inexpensive.

Title: Multipole connector for plug-in units - has adhesive metal foil as earthed screening plate on inside face of insulating block holding contact pins
Inventor: PELZL LEO
IPC: H01R13/658
Filed: 1979-03-12

Title: Sealed bottle closure - with plasticised plastics layer on bottom of polyamide push=on cap
IPC: B65D41/18
Filed: 1979-09-20
Abstract: A thin-walled plastic cap for pushing over the neck of a bottle has a knurled outside and detent ribs and a partial thread on the inside. The bottom of the cap is sealed against the bottle rim by a layer of plasticised plastic.

Title: Reflector location for non-destructive testing - by measuring closely neighbouring points from different positions or heads using ultrasonic echoes
Inventor: SEIGER HELMUT DIPL PHYS DR
IPC: G01N29/44
Filed: 1979-11-14
Abstract: A method of locating reflectors for non-destructive testing using ultrasonic pulses and pulse transition time or echo measurement enables accurate location of reflectors whose separation is small compared to their distance from the instrument. For each location procedure the workpiece surface (4) is scanned from two or more points whose coordinates (P1,P2,P3) are measured or predefined. The test head orientations and location distances (R1,R2,R3) are measured. The location of the reflector is defined as a volume (4) which is derived from the measured parameters. Construction of the volume involves the use of known, calculated, or estimated tolerance and deviation values for test head position and orientation and distance measurement. Alternatively, each point may be defined as a volume derived from measurements by two or more heads moving on a given path.

Title: Stepping circuit for converter - has switch for inverting signals with memory to control blocking devices for inhibiting appropriate channel
Inventor: KOEPE HANS-PETER DIPL ING
IPC: H03K5/153
Filed: 1980-02-13
Abstract: The stepping circuit has a switch (S) to invert or not invert an in-phase signal when one of two operating states exists. The direction of the signal state change following the appearance of the start signal is opposite or the same as a given direction.

Title: Electronic door lock combination - requires single key entry to terminate code and generated alarm signal with incorrect code
Inventor: SCHMIDT PETER
IPC: G07C9/00
Filed: 1980-05-14
Abstract: The combination lock system uses a keyboard and encoder but has the additional feature that the code entry must be followed with a further single key entry, the 'OPEN' code, and that an incorrect entry generates an alarm signal and disables the electronics for a specified period. The entire circuit fits into a wall switch recess. The keyboard (T) has an additional 'OPEN' key (O) which provides one input to two NAND-gates. The second input to the NAND-gates is the output from the key decoder integrated circuit. If this output is positive it will enable the first NAND-gate which triggers a monostable. The action energises the door relays. If it is negative, it will produce a negative going pulse from the second NAND-gate (G2), to trigger the second monostable (M2), resulting in an alarm signal (E).
