Patent DE-2559095-A1 (DE)
Title: Injection mould - ith movable side and top members has automatic degating and sprue removal device
Inventor: LEVITES SOLOMON
IPC: B29C45/38
Filed: 1975-12-30
Abstract: Injection mould having laterally openable side mould members which define open-ended mould cavity, base member and top closing member with sprue and runner passages. Automatic degating and sprue removal device consists of base mounted core pin which becomes anchored in the solidified sprue. Similar pins become anchored in individual runners. Opening movement of the top member causes the runners to break away at the gates and then pulls sprue and runners from the top member. Used esp. for moulding multiple articles with irregular shaped bottoms. Clean removal of sprue and runners during removal from the mould avoids subsequent manual work. The device avoids difficulty of operating with ejector pins on the irregular shaped bottoms. It is easier to change a machine for moulding different parts.

Title: Counter mechanism for conveyor car washes - has swinging actuator lever mounted on trolley for jam free operation
Inventor: WEIGELE GEBHARD
IPC: G06M7/00
Filed: 1976-02-19
Abstract: The counter mechanism for motor vehicle washing installations is for use with conveyor-type car-wash equipment. A hinged lever (5c) projects over the guide channel (2) for the vehicle wheel. The vehicle is propelled along the channel by transport rollers fixed to a continuous conveyor (4). The lever is attached to a coupling (8) and counter (9) supported on a sliding block (11) at the side of the track. The lever is held in a horizontal position by a spring and the sliding block held in its datum position by a similar spring (10, 12). When moving forward, the vehicle wheel depresses the lever at the same time carrying the moving carriage forward. After the wheel has passed over the lever, it and the sliding carriage are returned to their start positions by the action of the springs. Undue loading of the counter mechanism is thus avoided. Sticking of the lever in either the upper or the lower position is unlikely due to the action of the vehicle wheel and the moving roller respectively.

Title: Permonocarboxylic aq. concentrate stable to storage - contg. percarboxylic and/or carboxylic acid, hydrogen peroxide and water
Inventor: GROSSE BOEWING WALTER DIPL CHE
IPC: C07C409/00
Filed: 1976-04-12
Abstract: An aq. monopercarboxylic acid compsn. contains 0.5-20% of a 2-3C percarboxylic acid and/or the corresp. carboxylic acid, 25-40% hydrogen peroxide and the rest water. The compsns are used as organic oxidants, for treating hair and textiles, also as microbicides and virocides. Present concentrates, contg. e.g. 35-45% peracetic acid, 40-55% acetic acid and about 15% water require very careful handling for dilution in use because of the pungent smell and corrosive action of the concentrate. If only a 5-25% aq peracid soln is used, it is not stable to storage. The above are stable to storage, do not have the pungent smell and can be easily diluted without considerable safety precautions.
Patent DE-2618568-A1 (DE)
Title: Conveyor feeding metal bars to circular saw - has step drive for endless chains with aligned pushers which enter guide rails near roller track

A synchronised drive unit moves all the chains stepwise until one row of pushers meets a stationary limit stop on the clamping device fitted to the saw. The working surface of each pusher pref. consists of a roller so friction and wear between the pushers and the bars is reduced. The pushers enter guide rails near the roller track, limit switches stopping the conveyor at desired positions.

Title: Alphanumeric character information for computer input - is produced from video signal processed to provide pulse information of characters for computer input
Inventor: KIRSCH CARL-MARTIN DIPL ING
IPC: G06V10/10
Filed: 1976-07-02
Abstract: A video signal is processed and generates a pulse train that represents alpha-numeric data for entry into a digital computer. The video signal is processed to produce a horizontal scan signal, a vertical scan signal and a synchronisation signal. A start-stop oscillator controlled by the horizontal scan signal outputs a pulse train coupled to a gating circuit coupled to memory. X and Y address generators provide the necessary locations for data storage, determined by the computer. The process is initiated from the trailing edge of the square wave signal generated by the start-stop oscillator.
