Title: Self-excited synchronous generators excitation current regulator - uses time between start of thyristors ignition voltage and ignition point as control criterion
IPC: H02P9/30
Filed: 1968-11-30
Abstract: The excitation current regulator, for self-excited compound synchronous generators, has an operational amplifier bridged by a feedback capacitor and supplied at its input with three signals: The first signal is proportional to the difference between the actual and required values of the excitation current. The second signal is a voltage level which is always above the first level and is fixed by a zener diode; and the third signal is proportional to the turn-on voltage of the thyristor in the converter bridge. A diode ensures that only the negative sum of the second and third signals reaches the amplifier input. A transistor amplifier is coupled to the operational amplifier output and acts as a trigger supplying the ignition signals for the thyristor.
Patent DE-1948520-B2 (DE)
Title: Concentric tubular encapsulation for low temperature cable - includes internal axial stiffeners to prevent distortion of central tube
IPC: H02G3/04
Filed: 1969-09-25
Abstract: The system for low temperature or superconducting cables includes a concentric tubular structure, mainly of corrugated tubes, serves to thermally insulate the conductors, with the innermost tube serving as a coolant duct. To prevent distortion of this innermost tube to the point where contact with the next radially outer one could occur stiffening rods, typically of T-cross section, are inserted in the bore. Held by spacers attached to the tube wall these stiffeners are free to move axially and thus do not inhibit thermal expansion and contraction, and also allow the structure to take up bends imposed by the cable run. Spacers of poor thermal conductivity hold the outer concentric corrugated tubes apart.

Patent DE-2500687-B2 (DE)
IPC: G04F5/06
Filed: 1975-01-09
Abstract: The very thin tuning-fork shaped quartz-crystal vibrator (15) is mounted in a casing (30) and comprises two metal rods (31) which are disconnected at two locations of the base of the vibrator which are touched by two conductive films of electrodes for exciting bending in their plane. These electrodes have a particular electrically advantageous configuration allowing such mounting. The two rods pass through the wall of the casing. A certain space remains between the rear side of the tuning fork and the wall of the casing, in which space the two said rods can bend in order to neutralise the stresses which, otherwise, would result from a difference in temperature coefficient between the quartz crystal and the material forming the casing. This component is particularly suited to miniaturisation, its vibrator being used as time base in an electronic watch. <IMAGE>

Title: Apparatus for sensing RF current delivered to a plasma and waveform sampling circuit for use with such apparatus
Inventor: HOPKINS MICHAEL
IPC: G01R15/18
Filed: 1998-03-16
Abstract: An apparatus for sensing RF current delivered to a plasma includes an RF conductor along which the current is delivered to the plasma and which is divided into two parts along part of its length so that substantially equal currents flow in each part. A sensor device is inserted into the gap between the two parts of the conductor and includes first and second inductive loops disposed one n each side of the gap such that when an RF current flows along the RF conductor t magnetic flux surrounding the conductor which is generated by the RF current couples with the loops respectively in opposite directions relative to the sensor device. If a stray magnetic flux normal to the current direction couples with the loops in the same direction relative to the sensor device it will induce voltages in the loops which respectively add to the voltage induced by the RF current in one loop and subtract from the voltage induced by the RF current in the other loop. Thus by adding the voltages induced in the loops, for example by connecting them in series, the voltages induced by the stray magnetic flux tend to cancel.
Patent JP-S645503-B2 (JP)
IPC: H01P1/185
Filed: 1983-02-02
Abstract: An alternate-path phase switch has a primary conductive region and control regions which provide alternate paths in gaps formed with the primary region. Switching means, e.g. PIN-diodes, control the potentials on the control regions and select the path followed by microwave radiation. Each path results in a different phase in the output so the device acts as a phase modulator.

Filed: 1981-02-20
Abstract: In a hydraulic rock drill the valve (27) is controlled by two control lines (37, 42), each control line having a plurality of branches with ports (38-41 and 43-46) which open into the hydraulic cylinder of the rock drill. A valving pin (48) is slidable in a bore that intersects all of the branches of both control lines. By axially displacing the pin, the operator can pre-select the stroke length by deactivating some of the control lines and thereby the impact energy per blow. The control lines are deactivated in a predetermined bound relationship to each other.
