Patent DE-2547123-A1 (DE)
Title: LSI MOSFET delta coder and decoder - have identical D:A converters and up: down counter pairs with second counter directing first
Inventor: HINRICHSEN GERHARD ING GRAD
IPC: H04B14/06
Filed: 1975-10-21
Abstract: The large-scale-integrated MOSFET delta-coding system, for communications, consists of an integrating network in the coder and an identical network in the decoder to produce the analog signal. The integrating networks both consist of an up-down counter and a D-A converter. The decoder's first up-down counter is switched to 'count-up or down by 'up' or 'down' correction signals. Counting is relative to the halfway position. Its second up-down counter check the highest value output bits of the first counter and passes corresponding 'up' or 'down' correction signals to the first counter.

Title: Spring tensioned ventilation shutter - has spring moving disc to shut position on release by temperature sensitive locking device
Inventor: SCHADE MAX GUENTER
IPC: F24F13/10
Filed: 1975-11-27
Abstract: Ventilation shutter has a baseplate in a housing enclosed by an edge strip and with a semicircular opening in it. A ring encloses the opening, and incorporates grooves radially open on the inside. A semi-circular disc rotates about the ring centre, and a locking device engages with a groove in the ring in the open position, releasing at a preset temperature and allowing the disc to shut the opening off. A spring (41) acts between disc (2) and housing (1), being sufficiently pre-loaded to move the disc into the shut position on release at the locking device. Alternatively, the shutter can be so installed that the disc drops into the shut position under gravity on release.

Title: Radial bearing for large diameter rotors - has cylinders containing ported damping pistons connected to fluid under pressure for rotor location
Inventor: MILLER HELMUT DIPL ING
IPC: F16C32/06
Filed: 1975-12-22
Abstract: The large dia. rotor (1) is provided with a concentric axial projection (2) which is supported by radial pistons (4) mounted on the supporting structure (3). Three of these radial pistons (41,42,43) maintain the rotor in its central position. The pistons (44,45,46) damp out vibrations and the pistons (47,48) support the rotor weight. The cylinders housing the pistons are connected to a supply of fluid under pressure. Orifices in the pistons control the escape of the fluid so that the centering pistons (41,42,43) move to accommodate thermal expansion or contraction but maintain a constant pressure. The pistons (44,45,46) resist sudden shocks and damp out vibrations but move when subjected to a steadily increasing pressure.

Title: Mfr. of steel rod for drawing into wire - using controlled cooling after hot rolling with automatic compensation for recalescence
Inventor: ECONOMOPOULOS MARIO
IPC: C21D9/52
Filed: 1976-01-07
Abstract: In this process for making steel wire rod, on leaving the last stand in the hot rolling mill the rod is rapidly cooled to a temp. between 850 degrees C and that corresp. to the nose of the curve where the allotropic transformation of austenite into ferrite and pearlite commences, and the loose coils of rod are then subjected to a second cooling to complete the transformation. The progress of the cooling during transformation is observed and the temp. rise due to the exothermic recalescence is detected, additional cooling being applied at the location where the temp. rise occurs. A scanning pyrometer and a recorder are pref. used continuously, the recorder being linked to a controller which triggers the extra cooling achieved by jets spraying a mist of water in air. Consistent and accurate prodn. of the microstructure required for wire-drawing is obtd. The process is automatically controlled and the ductility of the wire obtd. is improved.

Title: Mine lagging mat connector securements - run as steel bands over mat rod end hooks and held by tongues, wires twisted through and round support between hooks
IPC: E21D11/15
Filed: 1976-02-10
Abstract: Mine road lagging mat connector consists of twisted wire linking the eyelets on successive mats by means of end securements which lock to the ends of the hooks and are drawn tight round the support channel held from behind by the lagging mat rod hooks.

The bands are locked into place from the opposite direction by tongues (56) forming part of the bands. The tongues are bent into the hook eyelets for this purpose, and the twisted wire (14) ends are looped round the associated bands, between the two legs (53, 54). Pref. the bands are doubled, forming a leg a piece (53, 54), the legs themselves recessed and fitted with the tongues on one rim of the recess where the tongues form part of the length of the rim only.

Title: Through bushing joining ducts with dissimilar dielectrics - are contoured to give constant electric stress on both sides
Inventor: MOSCH WOLFGANG PROF DR ING
IPC: H01F27/04
Filed: 1976-05-31
Abstract: The through bushing is typically for use in metal clad installations, e.g. for joining the HV terminals of an oil filled transformer with an SF6 insulated bus duct. The bushing comprises a disc designed to bolt between the mating flanges of the ducts, and has a central conducting bolt. The bolt passes through a central insulator typically of epoxy resin which is covered with a stress grading semiconducting layer. Sealing rings prevent the flow of oil to gas or vice versa. The contouring of the outer part of the disc is designed to give a constant electric stress along the surface, with the thickness determined by the mechanical pressure difference between gas and oil sides.

Abstract: A wall-junction profiled strip (1) has a plurality of profiled-strip portions butting against one another at the end sides. A wall-junction profile of this type is used for the overlapping fastening of a roofskin (3) on a wall (5) which rises up laterally next to the roof (4). One or more retaining strips (7) is/are provided on that side of the profiled strip (1) directed towards the wall (5). This retaining strip (7) forms an undercut with the profiled strip (1). A covering (6) for the joint (11, Fig. 3) can be pushed onto said undercut, the covering (6) having a cutout (8, Fig. 2), the cross-section of which corresponds approximately to that of the retaining strip (7). Good covering of the joint region is achieved by means of a wall-junction profiled strip of this type, and the profiled portions are also reliably aligned in the joint region. <IMAGE>

Title: HV trailing cable supervisory circuit - monitors power supply to excavators and has toroidal transformer in transients compensation circuit
Inventor: PUFF ERICH DIPL ING
IPC: H02H1/04
Filed: 1976-09-14
Abstract: The application is in the field of highly rated trailing cables as used to supply lower to excavators or drag lines on opencast sites. One core (3) of the power cable has a ring type current transformer (9) at the supply end (7). Its secondary winding feeds the earth and supervisory cores (4, 5) through a potential divider (P) and phase shifter (S). The potential derived from the current transformer is adjusted in magnitude and phase until it exactly compensates for the potential induced in the auxiliary cores (4, 5) by the current in the power cores (1, 2, 3). Switching transients do not cause high peaks in the supervisory circuit which the monitoring equipment (8) could interpret as a fault.

Inventor: MANI DIETER
IPC: G08B17/04
Filed: 1977-02-04
Abstract: The fire detection system has pipelines (3), which are provided with at least one pressure-monitoring device (2). Each pressure-monitoring device (2) has a switch (8, 9) for opening or closing as a function of the pressure in the pipelines (3), acting as temperature sensors. The switches (8, 9) are connected to an electrical alarm device. Such an alarm system is to offer the security of being operational at any time. For this purpose, the fire detection system is provided with an automatic testing device for the operational readiness of the system, which has a test pressure source (20, 21), which is connected to the pipelines (3). This test pressure source comprises, for example, a spherical glass bulb (20) with an opening, in which electric heating resistors (21) are arranged. The test device is provided with an electronic controlling means for periodic switching on and off of the test pressure source. The test pressure source may also be formed by a cylinder with a piston, which is set in motion by a motor. The advantage of such a system is that the automatic testing of the system can be carried out in a simple way, allowing the operational readiness of all the parts of the system to be checked automatically, the traffic on the carriageways of the tunnel not being affected in any way by the testing procedure. <IMAGE>
