Title: Sewage settling tank sludge cleaner control system - for automatic steering along straight path of travelling bottom scraper gantry
Inventor: BOTSCH BERTRAM DIPL ING
IPC: B01D21/20
Filed: 1972-08-26
Abstract: The gantry on which the scraper and its raising and lowering mechanisms are traversed along the tank has independently driven wheels at each side running on the flat tops of the side walls of the tank. Suspended from the underside of the gantry at each side there is a spring loaded pivoted sensing arm with a horizontal bar, the outer end of which is clear of the side wall surface as long as the gantry is roughly centred and steering parallel to the tank axis. Where the gantry deviates from its straight course, the sensor which first strikes the inside side wall face operates a limit switch in the motor control circuit for the wheel at the opposite side of the gantry, so switching it off and braking it to form a pivot for the gantry whilst the other wheel continues to be driven, and after a short period the sensor on the braked motor side is operated whilst that on the driven side is released so reversing the drive conditions of the two motors until the gantry as a while is castored back into its correct alignment and track (the separate wheels are not mounted on castor axles).

Title: Yarn brake, applying uniform tension aerodynamically - central metering valve controlled by manometer and air pressure monitors
Inventor: NICOLAUS HERMANN
IPC: B65H59/10
Filed: 1975-03-08
Abstract: A brake exerting a load on the thread vertically to tis line of direction, consists of braking surfaces forming a flow channel after the style of a venturi nozzle, which can be loaded aerodynamically by means of a laminar jet of air ejected through a nozzle and concentrically enclosing the thread. The speed of flow and throughput of the air are determined by a metering valve remote-controlled electronically. The aerodynamic loading of the flow channel can be effected either by pressure at the inlet or acuum at the outlet, and the braking load proportional to the flow speed is kept constant by a control circuit including a manometer. Provides a more flexible means of applying tension during operation and without the need to change components. Worn parts are very easily replaced.
