Title: Electronic control for smooth mode transitions - has indicators for stipulated and actual values used for manually-set and output values depending upon switch position
Inventor: PIWINGER FRANZ DIPL ING
IPC: G05B7/02
Filed: 1976-04-07
Abstract: The electronic control is for smooth transition from one mode of working to another. The indicators are each used for several purposes.

Title: Welding gun with pneumatic ram for capacitive discharge welding - with clamp for angle iron to be welded to workpiece
Inventor: MAUER DIETER
IPC: B23K9/20
Filed: 1976-04-23
Abstract: Welding gum comprises a pneumatic ram for capacitive discharge welding of an angle iron with an electrically insulated free arm to a workpiece. The ram is connected to a clamp which, on actuation of the ram, simultaneously clamps the angle iron and draws it backwards against a contact member which supports the angle iron with its uninsulated arm rearwards. The ram pref. consists of a ram-suspended guide and a resilient presser between which the insulated arm is inserted. The presser has a ramp which, on withdrawal of the ram entraining guide and presser, moves the latter relative to a stopping member, pressing the free arm against the guide; thus the angle iron is retracted and the inner surface of its uninsulated arm pressed against the contact member.

Title: Single column light barrier matrix - is used in reflex or transmitter receiver mode and is based on shift register principle for large area monitoring
Inventor: PAULY JUERGEN DIPL ING
IPC: G01B11/02
Filed: 1976-07-08
Abstract: Single column light barrier matrix in reflex or transmitter/receiver mode is based on shift register principle for large area monitoring. A monostable driving stage for a gallium arsenide diode is started through the trailing edge of the receiving pulse of the preceding light barrier receiving unit. Simultaneously the associated receiver for the light signal to be expected is started and its leading edge cuts off the transmitting pulse. The light barrier is started by means of an externally controlled starting generator. Starting pulses are supplied to the transmitter monostable only if the redundant storage stages are both in an unexcited state.

Title: Single-wall, heat-insulated, steel water-tank - lined with polyurethane or polystyrene foam which is coated with plastics aluminium plastics laminate
Inventor: SALDERN DIETRICH VON DIPL ING
IPC: B65D90/06
Filed: 1976-09-23
Abstract: Single-wall, heat-insulated, steel water-tank is lined with polyurethane or polystyrene foam, as heat-insulation, which is, in turn, coated with a 3-ply, water- and steam-proof, film laminate.

Title: Metals deposited by cathodic sputtering - in appts. using magnetic field to increase sputtering rate
Inventor: KURIYAMA NOBORU
IPC: H01J37/34
Filed: 1976-12-10
Abstract: Cathodic sputtering appts, in which a metal coating is applied to a substrate near the anode using an extremely low gas pressure. The anode and cathode are coaxial; and the cathode contains a magnet so the direction of the magnetic field crosses the electric field at 90 degrees; and the magnetic lines of force surround the electrons emitted by the cathode, the lines starting from, and returning to, the cathode. In one pref. design, the cathode is a water-cooled, hollow cylinder contg. a magnet; and several anode rods form a circular row round the cathode. The workpiece, or a circular row of workpieces, are located on the outside of the anode rods in the vacuum chamber. A gas pressure of 1-2 x 10-2 torr is normally required for sputtering. The invention requires a gas pressure of only 2-3 x 10-4 torr, for fast deposition of uniform coating while keeping the substrates at a low temp.

Title: Air separation into components - using molecular sieve adsorption with slow pressurisation after vacuum bed regeneration
Inventor: LEITGEB PAUL DR
IPC: B01D53/047
Filed: 1977-01-24
Abstract: Separation of gas mixt. into its components is carried out using a carbon type molecular sieve which adsorbe one component preferentially to others. The gas stream which is then enriched in the other component is taken as prod. The bed is regenerated by reducing the pressure to take off the other component e.g. with the aid of a vacuum pump. The repressurisation of the bed up to operating pressure prior to putting back on stream is done in two stages. It is raised during the first stage or stages to an intermediate pressure. It is then raised to the adsorption pressure. The repressurisation is carried out with non-sepd. gas. An enriched stream can be extracted from the bed during the pressure build up during the final stages of pressure build up. Used for sepg. gas mixts. esp. air into its constituent components. The problem with putting regenerated beds straight back on stream is that the initial gas stream has a rather elevated O2 content. The process described overcomes this problem.

Title: Lettering modifier using enlarger to project image - has film to be exposed mounted on horizontally movable carrier plate
Inventor: SCHMITZ DIETER
IPC: B41B23/00
Filed: 1977-01-29
Abstract: The lettering modification unit has an enlarger in whose holder the original lettering is placed e.g. in positive form. The projected image is directed onto film on a carrier plate which is mounted on four bolts engaging in corresponding boreholes of toothed gear wheels. The four gear wheels are driven by a central gear wheel which is connected by a friction coupling to a drive motor. By operating the motor to turn the carrier plate and hence the film, the projected image and film move relative to one another thereby creating a new version on the film of the original lettering.

Title: Welding data monitor - speeds up recorder chart speed when thresholds are exceeded
Inventor: DILTHEY ULRICH DR
IPC: B23K9/095
Filed: 1978-03-28
Abstract: A monitor for welding data records the welding current, arc voltage, welding speed and temp. All values are compared with set max. and min. thresholds. If a threshold is exceeded, the comparator causes the recorder to change to a higher recording velocity. This simplifies the finding of any irregular record by the supervisor because the higher velocity gives an immediate visual idication.
