Title: Automatic proportional regulator circuit - has PI elements in parallel providing disturbance free changeover between manual and automatic modes of operation
Inventor: NEPPACH HEINZ
IPC: G05B7/02
Filed: 1976-07-23
Abstract: A PI regulator circuit uses a proportional element in parallel with an integral element to provide a facility for disturbance free switching between manual and automatic modes of operation coupled with a facility to hold the output within a given range. The input (Xw) is summed with the output of a differentiator (6) and a threshold value (24), when operating in automatic mode. A proportional element (4) is coupled to parallel proportional (2) and integral elements (3). The output (YR) is fed over a delay stage (8) to threshold value comparators (10, 11) to generate a regulating signal. Switches are changed over (19, 20, 21, 17) for manual mode operation.

Title: Welded construction stable superconductor - has joint between super and normal conductors formed by explosive welding
Inventor: WALLBAUM HANS-JOACHIM DR RER N
IPC: H01B12/02
Filed: 1976-09-08
Abstract: The superconductor is welded under pressure to the normal conductor. the pressure for welding is obtained by explosive force. To ensure a sound, joint, the superconductor and/or the normal conductor are first roughened and cleaned. This prevents poor welding due to corrosion or grease. As material for the super-conductor, Niobium or Niobium alloys are normally used, while for the normal conductor, copper or aluminium are used. Both materials are used in sheet form, so that the end-material can be cut into strips. After welding, the super conductor is usually cold rolled in stages with stress relieving cycles.
Patent DE-2648673-A1 (DE)
Title: Mounting system for various dia. pipes - has protrusion on baseplate held between single size steel angle sections
Inventor: SCHMIDT RAINER
IPC: F16L3/24
Filed: 1976-10-27
Abstract: The mounting system secures pipes to a supporting structure, both being of varying sizes. A protrusion on the baseplate extends between a pair of steel angle sections arranged in relation to each other in a mirror image pattern, and is held in place by a mating plate on a screw. The design allows pipe mountings for different pipe sizes to be used with supporting structures of different dimensions without alterations to the baseplates. No further work such as welding or drilling need be carried out on the structure during installation. The dimension of the protrusion remains the same for all sizes of baseplate and steel angle section.

Title: Impurity concentration measuring device - uses capillary filled with mercury placed on polished surface of semiconductor chip
Inventor: TORREITER ANTOINE DIPL ING DR
IPC: G01R31/26
Filed: 1977-09-16
Abstract: The device measures impurity concentration in semiconductor ships by measuring the voltage dependence of a blocking mercury-semiconductor chip contact capacitance.

Title: Wideband measuring system for absolute signal levels - does not need absolute accuracy in input amplifier and divider and uses comparison signal derived from reference
Inventor: MILLER WOLFGANG DIPL ING
IPC: H04B3/48
Filed: 1977-12-10
Abstract: The wideband measuring equipment determines an absolute measurement signal level from the difference between the latter and the level of a constant frequency and amplitude reference signal. The measuring signal (UM) is amplified and rectified to coincide with a ref. d.c. voltage (U ref). A comparison signal (Uv) derived from the ref. signal is set to a level and amplified and rectified so that its voltage coincides with the reference d.c. voltage. The amplitude of the comparison signal is then the output signal from the equipment.

Title: Billet transport to transverse cooling beds - by offset roller tables with spiral rib rollers
Inventor: GIPPERICH KARL
IPC: B21B43/00
