Patent DE-2934429-A1 (DE)
Title: Single pipe with insulation or tubular bundle - for transporting chemically aggressive fluids has protective sleeve
Inventor: RATTI SATYA PAL DIPL PHYS
IPC: F16L53/00
Filed: 1979-08-25
Abstract: A single pipe with thermal insulation, or a system of pipes in the form of a cable comprising several parallel pipes one or more of which carries chemically aggressive fluids while the others carry heating fluids or fluids which are not chemically aggressive, the single pipe or the pipe system being surrounded by an insulating layer, has the pipes transporting chemically aggressive fluids provided individually with a protective sleeve which prevents chemically aggressive gases or vapours which diffuse out of the pipes from attacking other elements constituting the cable. The protective sleeve is pref. constituted of a material which is a good conductor of heat, e.g. pure lead, and which by chemical reaction with chemically aggressive gases or vapours which are formed by diffusion from the pipes carrying chemically aggressive fluids constitutes an anti-diffusion barrier preventing further diffusion of the gases or vapours. It is pref. applied by extrusion on the pipes. Chemically aggressive gases or vapours which diffuse out of the fluid pipes are prevented from attacking other constituent elements of the cable and impairing their ability to function.
Patent DE-2935186-A1 (DE)
Title: Contactless temp. measuring for moving strip - using heat conductive, radiation absorbing plate adjacent moving strip and at constant spacing from it
Inventor: FLECHER PIERRE DR ING
IPC: G01J5/52
Filed: 1979-08-31
Abstract: The temp. measuring is carried out by a stationary temp. sensor in a vacuum, exceeding 0.001 mbar. For this purpose a heat conductive, radiation absorbing plate is mounted adjacent the strip and a constant spacing from the same. The side of the plate away from the strip protects against heat losses. The temp. sensor picks up the plate temp. The process is primarily for vacuum coating plants and uses a measuring device with the strip guide. The used plate (16) near the strip (7) has a radiation absorbing surface (16d) and a heat containing insulator (19). Alternately the heat insulation may be provided by a hollow member surrounding the p plate rear side. The system enables the highest possible precision in maintaining a preset temp. level in strips, moving in a vacuum and not having an accurately definable emission capacity.

Title: Timing circuit for microprocessor control - with programmed switching of video recorder, and TV receiver incorporating back-up battery
Inventor: FUJII SATORU
IPC: G04G15/00
Filed: 1979-11-16
Abstract: The electronic timing circuit, includes a back-up battery (3) brought into operation upon failure of the current supply. Under these circumstances the circuit has a clock pulse generator (4), supplying pulses to a counter (5), with a store (6) recording time data supplied from the microprocessor (1) controlling programmed operation of the video recorder etc. A voltage detector circuit (2B) monitors the supplied current (2A), to cut-off the latter and replace it with the battery supply (3) if it falls below a given voltage. The microprocessor (1) responds to the cut-off signal for the current supply, to initiate a supply interruption routine, with the counter (5) counting the clock pulses and the store (6) supplied with the time data. The two values held by the counter and the store are added to obtain the current time when the supply is restored.

Title: Telephone exchange fault diagnostic routine - receiving faults detected by central processor in excitation register for fault locating and separately storing according to fault type
Inventor: BARTHOLOMAE HENRIK ING GRAD
IPC: H04M3/08
Filed: 1979-12-14
Abstract: The method of calling up the appropriate test programme is to check for faulty operation in a stored programme telephone exchange. The programme called up is decided by the type of fault condition being experienced. The programme indicates, after it has run, what measures should be adopted to remove the fault condition. When the common control (ZVE) equipment registers a fault condition it accesses the programme access register (ARF). A fault count is used to determine which diagnostic programme (A1, A2,..An) is used and gates (G4..Gn) are enabled as appropriate. At the end of the programme fault information (FI) output from the common control (ZVE) in conjunction with programme address and register controls (PZ,PR) outputs the data (FA).

Title: Nuclear reactor fuel element lock - in lower lattice plate by axially movable control sleeve and detent
Inventor: RAU PETER ING GRAD
IPC: G21C3/12
Filed: 1980-03-05
Abstract: Fuelelements for nuclear reactors, e.g. for breeder or converter reactors, are locked to counteract the dynamic pressure exerted by the coolant by fitting to the bottom part, with which the elements enter the lattice plate, with a longitudinally movable control sleeve When this control sleeve is not pulled upward by a central pull rod, rollers are driven outwards by a central cone and rest against salient parts in the lattice plate bore. This secures the fuel elements at the bottom where it does not obstruct the exchange or causes upsetting stresses like on the top end.

Title: Pipe drawing system - with working stroke taking place during carriage return
Inventor: OPPERMANN WILLI-FRIEDRICH
IPC: B21C1/20
Filed: 1980-03-21
Abstract: The system is for the straight drawing of pipes or solid profiles.

Title: Foil sheet temporary clamping device for transfer - has cam track operated spring-loaded sheet clamps with wedge action, shaped to lift clear for sheet positioning
Inventor: ZOLLNER HERMANN ING GRAD
IPC: B65G17/32
Filed: 1980-07-07
Abstract: The arrangement is intended for temporarily retaining sheet material, e.g. foil, between a lower element (5) and a pointed edge (2) of a spring-loaded (8) upper clamping bracket (1). The lower element is U-shaped, the outside of its upper flange forming the lower clamp jaw. The clamping bracket is approximately L-shaped and passes through an opening (7) in the flange near the web of the U. It also passes through an opening further away from the web in the lower flange so that tension on a clamped sheet causes wedge action increasing the clamping force. The portion of the clamping bracket passing through these guide openings is so curved that, in the open position, the sheet can be positioned on the upper flange from above. The clamping bracket is lifted to open, with its lower end (16') engaging a cam track (16).
