Title: Eddy current thickness gauge for conductive foils - uses phase-sensitive control circuit to reduce amplitude errors
Inventor: OTT ALBERT DIPL ING
IPC: G01B7/06
Filed: 1976-12-17
Abstract: The eddy-current measuring system for determining thicknesses of layers and electrically conducting foils comprises a measuring probe with coil driven from a reference HF generator. A differential amplifier has its inputs fed from the coil and from the HF signal via a network. The output of the amplifier controls the phase-shift of a shift network whose output passes to a phase-discriminator fed from the reference source. When the inputs to the discriminator have a 90 deg. separation, no output signal is produced. Any variation from this produces an output signal which is filtered and amplified in the control loop amplifier whose output is fed back to the phase-shifter. The system is insensitive to h.f interference and harmonics.

Title: Boring machine for turbine casing - has computer controlled auxiliary motor to control rate of feed
Inventor: HENNING RUDOLF DIPL ING
IPC: B23B5/36
Filed: 1977-07-28
Abstract: The guide blade support ribs of a turbine casing are machined by a special tool holder. The tool holder is mounted on a hollow shaft driven through spur and bevel gears. A second shaft is driven from the bevel gears and drives through a free wheel and gears. This shaft passes through the hollow shaft and drives a feed screw through further bevel gears. An electromagnetic coupling transmits the drive from a computer controlled auxiliary motor to the gear train. The computer controls the overrun of the second shaft w.r.t. the hollow shaft and so controls the feed of the cutter.

Title: Ceramic mouldings, esp. silicon ceramics - made by cold isostatic pressing in profiled plastic sheath reducing costly machining operations
Inventor: SIEBMANNS WILHELM DR ING
IPC: B28B7/34
Filed: 1977-08-29
Abstract: A pattern is made with the dimension of the pressed object required, and is then enclosed in an elastic sheath made of a thermoplastic. The sheath is opened by single cuts, so the pattern can be extracted and the sheath is then filled with a ceramic powder, sealed and cold isostatically pressed. The thermoplastic pref. melts at 50-200 degrees C but has a rubber-like consistency at room temp. (ca. 20 degrees C) and is esp. Vinamold (RTM). The pattern is pref. made of metal and briefly dipped in the molten plastic to form the sheath. After filling the sheath with the powder, welding is pref. used to seal the cuts. After isostatic pressing, the sheath is cut, and drawn off the moulding, or removed by melting. By using a sheath, with the desired shape and size, expensive machining operations are eliminated, i.e. the pressing is very near to finished size.

Title: Coaxial insulation application to cable etc. - uses several insulating webs supplied to winding mandrel in overlapping manner, with prior shape cutting of overlapping webs
Inventor: DIETZ HERMANN DIPL ING
IPC: H01B7/02
Filed: 1977-12-22
Abstract: The application of a coaxial insulation uses a signal inner conductor, or a rigid inner tube round a flexible inner conductor, as a winding mandrel for insulation tape, or web. Several such insulating webs are continuously applied to the winding mandrel in overlapping manner. The overlaps of two adjacent webs are so trimmed, prior to contacting the winder, as to form a narrow gap, between two adjacent webs. The winding mandrel and the web cutting device can be axially shifted, when one of them is stationary. Thus the gaps in individual lengths are covered. Alternately gaps in several layers may be covered by the top one.
