Title: Height-adjustable belt anchorage - has spring-loaded glide element engaging with serration when eccentrically loaded by belt
Inventor: HEYNE EBERHARD ING GRAD
IPC: B60R22/20
Filed: 1976-12-21
Abstract: The adjustable seat belt fitting mounted on the car door post is designed to block itself in any position, when the eyelet of the belt return fitting is subjected to a force with a direction markedly deviating from the vertical direction, following a sudden deceleration due to braking or impact. The door post is fitted with base plate bolted to the post by bolts. The edge of the plate pointing towards the rear of the car is provided with serrations.

Title: Automatic painting mechanism programming system - uses spray gun held by operator with inertial system attached
Inventor: PARDO PIERRE
IPC: G05B19/423
Filed: 1977-07-08
Abstract: The programming system is for an automatic painting mechanism following a continuous set path. The operation to be performed by the mechanism is initially carried out by an operator, using a conventional paint spray gun. To the latter an inertial system is attached, emitting electrical signals in direct proportion to the movements performed by the operator. These signals are amplified and processed, and delivered to a recording device. From here they are finally fed to the control unit of the automatic mechanism. The inertial system can have six or more axes on different devices, the positions of the devices in relation to each other being accurately defined and known. The set of devices is mounted on the master spray gun used for programming in a manner making alteration impossible.

Patent DE-2755403-A1 (DE)
IPC: G06F15/02
Filed: 1977-12-13
Abstract: The calculator is designed to permit, in addition to other operations, clear and easy unit changing. For this purpose, it comprises two switches having several positions and controlling logic circuits. The various positions of one switch correspond to various units of the same kind, or, as the case may be, to several units of the same magnitude but having different values. Furthermore, the calculator comprises two selectors (3, 4) connected to the logic circuits, which trigger the calculation of the change-over of a quantity expressed in a unit corresponding to the position of one switch and memorized in the calculator, into the same quantity expressed in another unit corresponding to the position of the other switch. The logic circuits may be arranged so that an alarm signal is generated when the switches are set on units of different magnitudes.

Title: Moving fabric alignment - uses rollers to compensate for effect of tension measurement before a pattern is printed
Inventor: ZIMMER PETER
IPC: B65H23/038
Filed: 1978-02-22
Abstract: In aligning a fabric web, partic. before it enters a printing machine, a constant tension is applied to the fabric so that the edges are correctly positioned. The tension is maintained so that the drawn tension on the fabric can be measured in its direction of movement, while independently driven rollers lying next to each other are used to eliminate any distortion incurred through the measurement process. The system ensures that the fabric maintains its alignment when it leaves a tension zone so that, on entering the printing zone, the pattern is correctly applied and that there is no fabric distortion which would affect the appearance of the printing.

Title: Reproduction method improving quality of frequency band limited speech - by adding stored spectral signals derived from full range prototype
Inventor: HOEHNE HANS DIETRICH DR ING
IPC: G10L21/02

Abstract: The speech frequency band is limited but additional signals are used, derived from available signals, to improve the quality of reproduction. Parameters (X) are derived from the patterns of available speech signals. Distances (alpha k) to other parameters (AK) are derived from these parameters (X). The parameters (Ak) are stored from a prototype characterising an equivalence class of sounds with limited frequency band. Parameters (BK) corresponding to parameters (Ak) are recalled. They are also stored from a prototype, but with a speech with the required frequency spectrum, and used for addition of spectral signals missing in the available speech signals.
