Title: Vidicon camera tube with charge coupled target - has semiconductor on screens inside, and signal plate with FET converter on outside
Inventor: HENNER DIPL-ING GERKE HANS
IPC: H01J29/96
Filed: 1973-08-01
Abstract: The vidicon camera tube has a transparent signal plate on the outside of its screen and the photosensitive semi-conductor layer on the inside facing the anode grid. The layer and plate form a capacitor bridged by the photosensitive resistance and coupled by one plate to an impedance converting a FET gate. The FET is mounted on the signal plate and connected to output couple the plate voltage variations produced by the electron beam and the light from the scene being viewed. The FET output electrode is coupled over a low ohmic resistor to the vidicon accelerating and grid electrodes. The system compensates for the vidicon low pass characteristics and avoids the detrimental effects of the target parallel capacitance and high internal resistance.

These plates are placed together with their grooved sides and the lattice type channel system is filled with concrete and forms a load supporting structure which is covered with facing material.
Patent DE-2345092-A1 (DE)
Title: Ink jet printer control system for improving print quality - has trigger circuit and sensor for detecting moment of droplet separation
Inventor: KATTNER ERICH
IPC: B41J2/01
Filed: 1973-09-06
Abstract: Ink droplets emerge from a jet and pass through an electrically charged guide electrode onto the recording medium which passes over a roller. A high voltage source supplies the jet with the necessary voltage for releasing the droplets. The charge displacements occurring as the droplets are emitted are tapped and fed to an amplifier via a coupling unit secure against high-potential breakdown. The charge displacements caused by the droplet formation time between jet and guide electrode are delayed by a phase shifting unit connected in series with the amplifier. The trigger unit coordinates the incoming character command with the signals from the jet so that during the flight of a droplet through the electrode the value of the signal fed via the guide amplifier is not altered.

A plastic medium is placed intermediate of each plunger and the respective face of the dies, so that this medium adjoins the central portion of this face and overlies the respective groove along the entire length, at least partly in cross-section. The stress gradient along the axis of symmetry of the dies is substantially reduced, and press. of >=150 kilobars can be produced. A tungsten carbide or hardened steel gasket is pref. disposed between the plunger and the solid medium adjoining the die face.

Title: Carrying clip for data cards - comprises two flat flexible plates and elastic band
Inventor: GARBADE MANFRED
IPC: B65D63/10
Filed: 1973-10-20

Patent DE-2421732-A1 (DE)
Title: Moulding gas turbine inner liner - from glass using mould having retra-ctable walls to relieve pressure on glass during cooling
Inventor: PEI YU KUN
IPC: C03B19/02
Filed: 1974-05-06
Abstract: In moulding large complex hollow glass articles, use is made of a mould having pairs of walls cooperable when clamped together in a closed position to define a mould cavity including a core carried by one pair of the walls. After introducing a charge of molten glass into the cavity and pressurising it, the pressure is subsequently relieved by withdrawing at least the core-carrying walls so that differential thermal contraction and expansion of the glass and the mould can take place to prevent fracture of the article. The technique is particularly adapted for making gas turbine inner liners which can subsequently be heat treated to convert the glass to a crystallized glass-ceramic material.

Title: Appts. measuring voltage reduction because of creepage - has vibrator connected to vibration starting-signal generator
Inventor: YAMAZAKI TAKAO
IPC: G01L5/04
Filed: 1974-05-29
Abstract: A vibration is generated as a result of the electromagnetic coupling of a steel wire under a constant voltage. A vibration pick-up scans the vibration of the steel wire electromagnetically and a counter measures the time during which the vibration pick-up scans the free damped vibration on the basis of the natural vibration of the steel wire, generated by the vibrator, for any number of vibrations, e.g. from a few tens of vibrations up to a few hundred vibrations per second. A time delay circuit on the voltage pick-up output side ensures that the time in which the vibration pick-up has acted on the damped vibration can be measured only after an interval of so many seconds.

Title: Lagging sheet for mine backfills - has double sheet spot welded from singles to form sealed surface with inserted sheets
Inventor: HACK KLAUS DIPL ING DR
IPC: E21D11/15
Filed: 1974-07-29
Abstract: The lagging sheet for use in mines, where it provides a sealed surface suitable for backfilling with instant packing material, consists of two sheets placed parallel to one another and spot-welded to produce a double sheet in which the internal spot welds are minimally spaced from the rims sufficient to allow an identical sheet to be inserted between, on all four sides. The sheets thus overlap to form a sealed join between for backfilling purposes. It is also possible to insert several double sheets into one another to form a sealed surface, or again arrange single and double sheets in a staggered array. The sheets may also be bent to produce curved shuttering surfaces.

Title: Three jaw chuck for lathes - has jaws swivelling about point and worm operated with additional hydraulic clamping
Inventor: ROMERO EMILIO
IPC: B23B31/12
Filed: 1974-09-27
Abstract: The three jaw chuck has three arched arms operated via a worm drive. The arms pivot about one end and grip the workpiece at the other end. A hand operated hydraulic pump is used to give additional clamping force to the jaws. The hydraulic pump is in the form of a piston pump which is operated by a screw by means of a spanner. The pressure generated in one piston pump is applied to all three clamping jaws by means of clamping pistons. The clamping pistons have sloping faces at the ends which are opposite the end to which the pressure is applied. The sloping faces engage with pins which transmit the forces.
