Patent DE-2549221-A1 (DE)
Title: Label coding binary information - uses different coloured spherical reflectors for remote automatic read:out by electronic camera
Inventor: WALTERSPIEL JUAN N
IPC: G09F3/02
Filed: 1975-11-03
Abstract: The label comprises a number of different coloured reflectors, allowing remote automatic read-out of information in binary form. The number of reflectors of each colour and/or the number of different coloured reflectors represents the data bits. The reflectors may comprise spherical lens elements and the label information may be read by using an electronic camera. A wide spectrum light source is positioned concentric to the camera objective, so that the light is reflected back onto it by the different reflectors. The camera has a disc with a number of light-sensitive lines, supplying pulses to a counter or decoder, the number of lines corresponding to the number of different colours of the reflectors.

IPC: B65G65/48
Filed: 1976-02-07
Abstract: Machine meters dry material at one pressure for continuous mixing, homogenising etc. with wet or other dry material at a different pressure. The metered dry material is received by a variable-volume and movable transport vessel (13) accommodated in a slide or rotor, its volume being varied by a flexible diaphragm (6) from nil to maximum, the diaphragm being actuated by a control chamber with a hydraulic, pneumatic or electrical control system. The vessel is completely sealed both when the slide or rotor is stationary and moving, and the sections of the machine are completely sealed from each other and the atmosphere. the material is delivered to the operation vessel forming the discharge station, and the metering is adjusted by varying the machine speed and/or the transport vessel volume steplessly. The material is forced into the operation vessel by reducing the transport vessel volume, and on further movement the diaphragm is scraped free of any particles of any material remaining.

Title: Adjustable aerofoil for vehicle rear window - has sprung arm mounting and with ratchet holds for variable setting
Inventor: HABLITZEL HERMANN ING GRAD
IPC: B62D35/00
Filed: 1976-04-01
Abstract: The rear window is fitted with an aerofoil (1) to deflect an airstream over the window and prevent build up of dirt. The aerofoil is mounted on sprung legs (10) and is secured in the optimum setting by a ratchet (16), so that the amount of air scooped over the rear window can be adjusted. When not required, at high speed, the aerofoil can be swung down below the roof line. The legs are set in a non parallel setting so that when the aerofoil is tilted down it assumes a more horizontal pose. The amount of tilting is limited by stops and the whole assembly is mounted on elastic pads for vibration damping.
