Title: Collapsible umbrella with triple section ribs - main slide locks in shaft handle until inner rib sections are telescopically extended
Inventor: WEBER HEINZ
IPC: A45B25/08
Filed: 1975-03-06
Abstract: The collapsible umbrella comprises triple-section ribs and a telescopically extending stock with an auxiliary and a main slide member and handle wherein the main slide is designed to lock on the handle but can be released by the tensile force of the two inner rib sections when these two are telescopically extended. In this way the main slide member remains locked on the handle until the two inner telescoping rib sections have been extended, so that the locking pawl of the main slide remains free of stress and the handle itself acts as an enlarged handle for the main slide. The handle can be provided on the inside of the known slide inlet shaft with a core member with resilient claws which lockingly engage on a lower bead on the slide.

Title: Machine tool control with TV cameras - has sensor arrangement for controlling programmed auto handling systems
Inventor: BRETSCHI JUERGEN
IPC: B05B12/04
Filed: 1975-03-27
Abstract: The sensor arrangement for controlling auto handling systems by means of T.V. cameras feeds the picture into the programme of the handling system by limiting some of the tool (object) positions to a few T.V. lines at significant points during the determination of the type of tool and its positioning. This simplifies the identification procedure with less apparatus. The procedure involves feeding back of the signal for evaluation of the T.V. line dater. The programming is made in a picture-screen-service-dialogue and the evaluation circuit for each object comprises a fixed number of building blocks programmed to the objects. there are usually more than one T.V. camera which pick up the object with a shine through or illumination light. the correct position of the object is determined by the occurrence of the maximum intensity of the video-signal and the receiving angle.

Title: Return force generator for scientific instrument - uses electromagnet with variable excitation interacting with permanent magnet
Inventor: EUER HARTMUT ING GRAD
IPC: G01D11/14
Filed: 1975-05-13
Abstract: The return system in a scientific instrument acts in a fashion analogous to a spring, but uses a system of electromagnets (1a) which are arranged to act as a linear actuator when excited. There is a conductor (4) running the length of each block of magnets and a series of alternate N and S poles is produced. The N and S poles interact with corresponding N and S poles on a permanent magnet (1a). The conductor (4) is shaped as a square wave and when a current passes through this conductor, the resulting interaction forces the magnets towards their zero position. Within limits, altering the magnitude of the current alters the position proportionately. This is analogous to a spring. If the plates (3) forming the body of the electromagnet are conductors of electricity then damping forces need to be compensated.

Title: Quick drying hair dryer - has hollow toothed comb attachment to direct air upwards through hair enabling use of higher air temperature
Inventor: THEVES BRUNO DR
IPC: A45D20/12
Filed: 1975-07-04
Abstract: The accessory for hair dryers is in the form of a hollow toothed comb. Each hollow tooth is closed at the sides and underneath and open only along an oblique upper surface. This ensures that the hot air is directed obliquely upwards. The cover part (2) limites the size of the opening while deflecting the upper layer of air from the dryer downwards onto the lower part of the tooth. Knobs (3) are added to each tooth on its underside to ensure that the heated surface of the comb teeth does not come into contact with the scalp. The air from the tooth is blown upwards through the hair at a tangent to the scalp. This method allows the temperature of the air to be raised without the danger of burning the scalp. The higher air temperature dries the hair more quickly.

Title: Terrain perspective display radar - compensates weakness of distant echoes to produce even brightness
Inventor: LEYSIEFFER HANS DR ING
IPC: G01S7/06
Filed: 1975-09-29
Abstract: The antenna (1) is sharply focussed in the azimuthal direction and direction mainly along the ground. It scans the area to be surveyed. A horizontal deflection device (6, 8) controls the picture element on the screen in accordance with the antenna-azimuth angle. A vertical deflection unit (12, 13) moves each picture point vertically up from the screen edge when a pulse is sent out. Its vertical velocity is proportional to the product of the reflected power received and the reciprocal of the distance of the reflecting point. A device (9, 11) controls the reflected signal gain in accordance with the distance to the reflecting point, so that the intensity of the reflected signal, and thus the picture point brightness is independent of the distance.
