Title: Padded board for hardening karate hands and feet - is mounted to absorb some of force within structure
Inventor: KANTNER MICHAEL
IPC: A63B69/00
Filed: 1975-10-22
Abstract: The pad (1) which is to be struck with hand or foot, is fixed to a vertical board (3) whose lower end is fastened to the short vertical of a J-shaped angle-iron frame (9). The long vertical is screwed to a wall, and the horizontal to the floor. A horizontal strut (12) bolted to the long vertical, reaches across the angle-iron frame to the vertical board (3). This strut takes some of the force of the blow, and reduces the stress where the board joins the iron frame. The iron frame's long vertical is pierced by several holes (11), so that the horizontal strut can be bolted to it at various heights, to alter the resilience of the board behind the pad (1), and so vary the intensity of the training.

Title: Vehicle anticollision radars head-up display - uses windscreen reflected display of light diode matrix indicator
Inventor: HORMANN GERHARD
IPC: G01S7/26
Filed: 1975-12-18
Abstract: The head-up instrument display system for motor vehicles is for use with vehicle-mounted radar anti-collision equipment. The display of data uses a series of LEDs mounted near the windscreen so that light is reflected from the windscreen to the eyes of the vehicle driver without distracting his attention from the road ahead. The LED matrix can be arranged so that certain patterns or colours indicate the range and bearing of obstructions ahead of the vehicle as detected by the radar. The information is first stored in a register before being passed to the display. The diode matrix (1)(2) may be mounted in a suitable position on top of the dashboard (5) so that the display appears in the driver's line of vision through reflection.

Title: Parchment prodn. - using multi-layer paper where one layer parchmentises less than the other layers
Inventor: DIRKS BERND
IPC: B32B29/06
Filed: 1976-04-09
Abstract: In the mfr. of parchment paper from multi-layer raw paper material, >=1 layer is parchmetised less than >=1 other layer in the paper. Specifically, the raw paper layers for parchmentising are developed by chemical treatment to give absorbent layers. At least one layer is chemically treated to give it a reduced parchmentising character by treatment with wet strength and/or adhesive agents. The raw material is produced by a paper making machine as a multi-layer paper. Process gives a parchment paper material which is less likely to become brittle and has a high resistance to tearing across its width. The basic paper has a high resistance to wetness and can be mfd. with a higher machine capacity, giving a light parchment.

Title: Variable inductance angle measuring transducer - has two balanced coils mounted on common core with movable ring short circuiting magnetic circuit
Inventor: ZABLER ERICH DR ING
IPC: G01D5/22
Filed: 1976-07-24
Abstract: A simple angle measurement transducer depends on a variable inductance principle and consists basically of two mutually opposing coils mounted on a common core. Two E-shaped ferrite cores (10, 11) are mounted at an angle, typically 90 deg., with a jointing magnetically-conducting prism (14) completing the magnetic circuit between them. Two balanced coils (12, 13) wound in antiphase are posiitoned, one on each core and a ring (15) short-circuiting the magnetic circuit can move on the core between them according to the angle concerned. The coils are serially connected and are excited by an oscillator and inverter. A phase-sensitive detector monitors the voltage of the common point. The phase of this represents the angle being measured.
