Patent DE-2432116-A1 (DE)
Title: Correction of distorted image on image intensifier - involves bundle of optical fibres with concave input surface
Inventor: DAMMANN HANS DR
IPC: G02B6/06
Filed: 1974-07-04
Abstract: The distorted image which is produced on the screen of the image intensifier is projected by a lens onto a concave surface forming the input surface of a system of optical fibres which reconstructs the original photographic geometry when the image was generated. The optical fibres are focussed and the rectified image which is produced on the optical fibre output surface is transferred to a recording medium. Pref. the depth of focus of the image projected on the concave surface is increased by stopping down the lens which is used to perform the focussing. The system may be used to facilitate radiography.

Title: Impact sensor for airbag release - with irreversible mating of contacts for failsafe operation even if corroded
Inventor: BABITEKA RUDOLF
IPC: B60R21/01
Filed: 1974-07-22
Abstract: The airbag system is released by the operation of impact sensing contacts which are arranged in such a way that they operate even when covered with oxide and dirt after years of inactive storage. The contacts are pressed together through the action of the impact and are scraped together with great force. A simple design can have a spring clip forced over a pointed contact, or another, a cone shaped contact pin forced into a sharp open tube contact. The impact sensor thus operates in a fail-safe mode. One of the contacts extends vertically and the other curved contact is pushed around it by a concave surface attached to the weight.

Title: Assembly jig for microfiche using stencil plate film and adhesive tape - has a combined holding frame for tape roll and pressure roller
Inventor: RICHTER WOLFGANG
IPC: G03C11/14
Filed: 1974-07-24
Abstract: The design is intended to simplify and speed up the assembly process, to reduce costs and to improved quality. The roll of self-adhesive tape (5) is fitted into the upper part of a frame which also carreis a pressure roller (2) in the lower part on a spindle which is parallel to that of the tape spool. The frame is located in guide slots (3) in front of the stencil (4) by spindle projections. Initially a short length of full width tape is applied to the edge (6) of the stencil block which carries the films (7) on the upper surface. The non-adhesive side of the tape is in contact with the pressure roller. The stencil is then moved relative to the frame to draw the tape under tension and pressure over the film. The process ensures that all air is excluded between film and tape. This enhances the quality of copies.

Title: Densitometer with a U or a V-shaped oscillating tube - can be used for component identification or measurement of its concentration
Inventor: KOUKOL HUBERT DR
IPC: G01N30/62
Filed: 1974-08-01
Abstract: The densitometer can also measure concentration distribution of individual substance components in a chromatograph carrier liquid. It is based on measurement of the tube natural frequency. The tube is clamped at one end and excited into oscillations at a farthest point from the clamping point. It can be used for liquids under high pressure, when its inner diameter, does not exceed 0.5 mm. Two oscillating tubes can be used, similarly excited and connected in a differential circuit. Carrier liquid flows through one tube, and carrier liquid with the substance to be identified flows through the other. It is for use in high pressure liquid chromatographs.

Inventor: KINJO KIKUO
IPC: G03C7/25
Filed: 1974-10-14
Abstract: A colour image is produced by (a) producing a coloured image with a colouring matl. (I) dispersed in a hydrophilic high polymer coating (II); (b) placing an image transfer sheet, consisting of a hydrophobic high polymer (III), at a certain distance (pref. 5-100 mu) from this; (c) introducing an org. solvent (IV) which can dissolve (I) and penetrate the transfer sheet into this gap; and (d) transferring (I) to the transfer sheet, perf. at 40-150 degrees C.

Title: Linear thrust motor using centrifugal force - has endless chain with masses guided to pass through different radii
Inventor: RUEDEL GERHARD
IPC: F03G7/10
Filed: 1974-12-21
Abstract: Linear thrust motor comprises two wheels over which is trained a chain or similar endless flexible member. A series of small masses are connected by pivotal links or arms to the chain at regular intervals therealong. A guide along the straight runs of the chain causes the masses to pivot about their connection to the chain so that when the masses pass around the one wheel they are radially outside the chain pitch pitch circle while when passing around the other wheel they are radially inside the pitch circle. The greater centrifugal force acting at the one wheel is said to provide a linear drive.
