Patent DE-2456243-A1 (DE)
Title: Used relay contacts treatment - uses HV light arc with contact surface as its electrode at frequency exceeding specified value
Inventor: BAUMANN JOSEF
IPC: H01H1/02
Filed: 1974-11-28
Abstract: The contacts for switchgear, preferably relays, are additionally treated by using the contact surface once or several times for a time period of one to five seconds as an electrode of a high voltage light arc, at a frequency of more than 10 kHz. This treatment provides a sufficiently high contact resistance in a rapid process. In addition the dynamic contact resistance reaches in the shortest possible time the lower value of the static contact resistance. The applied voltage depends on the material and contact spacing, preferably in normal air treatment 10 to 15 kV is sufficient.

Abstract: A thread breakage detecting device, esp. for looms in which groups of threads, esp. for pile, are only lightly tensioned; and of the type having a contact rail and platines with elongated slots, supported by the threads, which when they fall, close the circuit and generate a signal for stopping the loom; forms part of a circuit in which a relay for stopping and starting the loom, is put in a state of rest in which it is isolated from the signal source, whilst an alerting circuit, responding directly to the signal source prepares the start and stop relay, through a timer, for action, by putting it in direct contact with the signal source. The essential parts of the circuit can be interchanged to suit partic. conditions, by means of cards to be plugged in, and signal lamps show the situation in the circuit. Highly sensitive whilst preventing stoppages due to false alarms. The loom is stopped by a yarn breakage but not by a brief signal generated by rebounding contact closing the circuit momentarily.

Patent DE-2526095-A1 (DE)
Title: Continuous purificn. of petroleum refinery effluents - by biological oxidn. and aeration between stages
Inventor: GRUTSCH JAMES FRANCIS
IPC: C02F9/00
Filed: 1975-06-11
Abstract: Activated sludge treatment of effluents from chemical factories, and partic. those from petroleum refineries, is effected in four stages: (1) primary treatment by sedimentation; (2) intermediate treatment by equalisation, pH adjustment, coagulation, oxidn. and filtration; (3) secondary treatment by aeration between the stages, biological oxidn., clarification, thickening and aerobic digestion; (4) tertiary treatment by coagulation/flocculation, filtration and adsorption on activated carbon. The refinery effluent enters the plant at the sump and then into a conventional separator where considerable quantities of oil and solids are eliminated. The chemical effluent enters at compartment of the multi-compartment tank. The mixed effluents pass through pipes, to press. filters and to the biological treatment section; this comprises four stages, a contract stage where the effluent meets the activated sludge, a clarification stage, a thickening stage and a digestion stage. The decomtanminated water then flows through a second battery of filters and is rejected into a watercourse. When rejected the evacuated water contains at least 5 ppm. of dissolved oxygen so that it does not therefore lower the quality of the receiving stream. Biological degradation is improved by keeping the temp. in the equalising tank at 32.2-37.8 degrees C.

Title: Waste protection for abrasion grinding machines - cylinder pressure chamber is connected to metering vessel and cut-off valve
Inventor: RICHTER RUDOLF
IPC: B23D47/10
Filed: 1975-06-23
Abstract: Waste protection for abrasion grinding machines by which a dropping of the grinding disc in the reversal points of the carriage above a tolerable amount is eliminated where the piston rod side pressure chamber (4b) of a double-acting application cylinder (4) is connected with an adjustable metering vessel (10) and an electro-magnetic cut-off valve (6) controlled from pulse emitters (U1, U2) via a delayed time relay. If desirable the electrical regulation can be replaced by pneumatic construction and switching elements without reducing the overall reliability. The waste path of the disc at the reversal points of the grinding carriage can be set in advance thereby preventing a sideways travel of the grinding disc on the workpiece.

Title: Double:acting piston engine with a rotor - has fully balanced layout with central crankshaft
Inventor: STEINBACH DIETER DIPL PHYS
IPC: F01B7/00
Filed: 1975-10-07
Abstract: The double-acting piston engine with a rotor and fully balanced is esp. suitable for use as a compressor, pump or gas/IC engine.
