Patent DE-2526326-A1 (DE)
Title: Motor vehicle for traction and road travel - has optionally coupled all wheel steering and drive and front steering
Inventor: GOEBEL HANS DIPL ING
IPC: B60K23/08
Filed: 1975-06-12
Abstract: The drill is for constructional motor vehicles travelling on difficult ground, and has optionally coupled all wheel drive and all wheel steering. The actuating elements for the drive and steering system are coupled so that the all wheel steering is coupled when also the wheel drive is coupled, which prevents over-loading of the rear axle, for protecting the power transmission universal joints at the rear. It is possible to use a rear-axle of lighter construction. The front wheel can be steered optionally with or without all wheel drive for travel on road or on less arduous ground and it is used especially for traction work. The all wheel steering and driving is used for work on heavy ground.

Title: Typewriter for printing lines of equal length - has elastic ink ribbon acting as intermediate store for line prior to printing
Inventor: JANSEN HEIKO DIPL ING
IPC: B41J5/30
Filed: 1975-08-04
Abstract: An elastic plastic ribbon serves as the intermediary store and has an ink layer whose width is greater than the height of the letters being printed by the movable, spherical type head. A paper strip and the ribbon are fed from a common spool across the printing position to a common take-up spool. The strip passes between ribbon and sheet. Electromagnetically-operated ribbon clamps, of which the right clamp is movable, are located towards the end of the platen. At the beginning of typing the left clamp is closed, the head with letters in negative form types the line transferring the letters, now in positive form, to the strip. The strip is raised so that it can be viewed and the ribbon can be stretched to justify the line. The line can then be transferred to the paper by using the head as a hammer moving from one line end to the other.

Title: Removable drain inspection plate - has load bearing steel plate upper with additional reinforced concrete ballast cast to underside of plate
Inventor: WEILER WALTER
IPC: E02D29/14
Filed: 1975-11-11
Abstract: The removable inspection cover for drains (1) has a load bearing upper steel plate (3) whose surface is patterned to prevents skidding of road vehicles.

A concrete slab (4) of smaller lengthways dimensions than the plate is cast onto its underside and is reinforced by steel bars (7). The slab provides no load bearing but only additional weight to the cover to prevent it form moving when driven over. Holes in the plate between the edge of the abutment and the edge of the slab give ventilation to the drain.
Patent DE-2551435-A1 (DE)
Title: Sensor for yarn stop motion has earthed and active electrodes - forming guide duct through which the yarn passes
Inventor: DOMIG RENE
IPC: G01P3/481
Filed: 1975-11-15
Abstract: An electrodynamic sensor for a yarn stop motion comprises a body of pref. insulating material and an earthed electrode and active electrode which are pref. electrically insulated and which are arranged around a duct in the body through which the yarn passes. The presence of the yarn in the passage effects the electric field between the earthed electrodes and active electrode, so that when the yarn breaks and is no longer in the duct the field changes and is sensed so that a textile machine processing the yarn can be shut down. The sensor produces a particularly strong signal when yarn breakage occurs, thereby ensuring consistent shutting down of the textile machine when a yarn breakage occurs.

Title: Optical computer memory system - uses laser radiation with alternative mode changing memory cell state through input:output unit
Inventor: JAVAN ALI
IPC: G11C11/42
Filed: 1976-07-16
Abstract: A memory system for computer technology operates with access times of the order of picoseconds because it transmits the information to and from the memory cell by light rays. The bit memory consists of conductors and aluminium-aluminium oxide-lead junctions on an insulating substrate. The memory is linked to an input-output unit which responds to stimulation by Ar, CO2 or CO laser radiation. The optical radiation used has alternative features which produce alternative electrical effects so that each input-output unit responding to these effects causes its memory cell to take on one of its two states.

Title: Semiconductor solar cell - produced by dripping molten silicon on revolving rocking graphite substrate
Inventor: MEULEMAN JOHANNES
IPC: B05D1/00
Filed: 1976-08-31
Abstract: A solid layer is applied to a substrate, partic. for the mfr. of solar cells produced from Si semiconductor wafers, by allowing a liquid from which the solid is formed to trickle on the revolving substrate. A periodic motion is superimposed on this motion to vary the position of the plnae of the substrate surface. This is done by gas blasts on the underside of the water so that the latter swivels on a central ball joint. This is an inexpensive way of producing solar cells of =100mm dia. and with a semiconductor thickness of 10-400 mu on a graphite substrate.

Title: Transmission system for video signals - has alternating line reduced bandwidth transmission of luminance signal
Inventor: HEITMANN JUERGEN DIPL ING
IPC: H04N7/12
Filed: 1977-01-17
Abstract: The transmission system for video signals is designed for the reduced bandwidth, separately-coded luminance signal transmission in that only every second line is transmitted. A correction signal is derived from the transmitted signal. The filtered luminance signal is delayed and fed to a switching system on the input of an a-d converter. The direct signal is fed to one input of an adder whose second input is fed from a second delay stage. The total delay is that of one line period. A correction signal is derived from an averaging stage and filtered. This signal is switched alternately with the original delayed signal to the input of the A/D converter. The switch is driven at half line frequency.
