Patent DE-2639087-A1 (DE)
Title: Tangled component separating process - which repeatedly lifts and lowers mass until it has completely disintegrated
Inventor: STICHT WALTER
IPC: B65G47/14
Filed: 1976-08-31
Abstract: The process separates components tending to stick together, such as hooks, springs washers etc. The mass of components supported on a base is gripped at the top, and lifted, and then lowered again and/or released, this operation being repeated until it has disintegrated. The items remaining behind on the base are continuously or intermittently removed and further separated, sorted or aligned as necessary. The mass can be accommodated in a hopper (1) above an outlet (2), and lifted by a mechanism above the hopper (8) equipped with a grab, magnet, suction head etc. There can be a rotary brush at the hopper outlet, its bristles being interchangeable or adjustable to vary the effective length (4).

Title: Automatic aperture setter and film drive for cine camera - has photoresistor and three input OR=gate connected to comparator circuit
Inventor: WAGENSONNER EDUARD ING GRAD
IPC: G03B7/085
Filed: 1976-10-29
Abstract: A photoresistor (9) is connected to the input of a comparator circuit (23, 22) and an electro-magnetic motor (16) for controlling the aperture (14).

Title: Anchorage preventing wind entangling linen round line - formed by weighted protectively surfaced clamps of eyelets and hooks
Inventor: ILLGUTH GUSTAV
IPC: D06F57/00
Filed: 1978-01-28
Abstract: Articles of linen hanging on the washing line are prevented from being blown over and entangled by the wind by means of a weighting or anchoring arrangement. The inconvenience of having to rearrange the items continuously, and the longer drying time necessary in consequence are avoided. Clamps may be used which have ribbed surfaces so that the space between jaws is also dried, and they may also be covered with plastic to prevent soiling of the articles of washing. Wts. of various kinds from lead discs to bars may be incorporated in the clamps and eyelets of fabric may be attached to the linen for accommodating hooks.

Title: Intruder resistant motor vehicle door lock - has three settings, with final one blocking unbolting action
Inventor: KINZEL HEINZ
IPC: E05B83/36

Title: Pulsed Doppler radar receiver system - has noise signal suppression circuit with target threshold amplitude detection and range noise detection
Inventor: GUENTHER HEINZDIETER
IPC: G01S7/36
Filed: 1978-05-29
Abstract: A circuit for suppression of noise signals in pulse Doppler radar receivers with permanent echo suppression and several channels each corresp. to distance measurement ranges suppresses intermittent line noise or jamming noise covering several channels or distance ranges whilst maintaining high receiver sensitivity. An evaluation circuit using an intermediate store forms the difference or quotient of the signal amplitude of each channel and that of the previously scanned channel to produce reference signals. These are interpreted using a two-level threshold switch for amplitude detection of real target signals. Signals occurring in a given number of channels are interpreted as noise.
Patent DE-2827149-A1 (DE)
Title: Printing of multi-coloured designs e.g. emblems - using cliche with shallow recesses filled with colouring matter
Inventor: AUGENLICHT IRENE
IPC: B41M1/20
Filed: 1978-06-21
Abstract: A method of printing emblems, badges, stickers etc. consists of first making a cliche (1) by marking out the required design into the regions of different colours. Each coloured area (3) forms a shallow depression bounded by ridges (2). Colouring matter is applied to all areas of the same colour and then hardened by heating. This process is repeated with all the required colours. The colouring matter is then softened by means of a suitable solvent and covered with the fabric or other material onto which the design is to be printed. The fabric and cliche are then placed together under a press and heated in order to transfer the design to the fabric.

Title: Static convergence adjustment for in-line colour picture tube - has hard magnetic material convergence device repeatedly magnetised inside tube
Inventor: STIEFKEN HANS DIPL ING
IPC: H04N9/29
Filed: 1978-08-26
Abstract: The convergence device is made of a hard magnetic material and is mounted inside the tube. It is magnetised by a coil put on the tube neck, so that the three electron beams intersect in the centre of the screen, in the shadow-mask plane. The electron beam is blanked and the convergence device is magnetised. The magnetising current is switched off and at least one electron beam is brightened up and the position of the light spot is registered. The beam is then blanked and the magnetisation is again carried out in accordance with the light spot position. The process is repeated until the three electron beams intersect as required.
