Patent DE-1929262-A1 (DE)
Title: Method of controlling electrode setting in an electrolysis - furnace for minimum energy consumption
Inventor: JOHANN THOMAS DR
IPC: C25C3/20
Filed: 1969-06-10
Abstract: The optimum setting of the electrodes in an electrolysis furnace is obtained by making an arbitrary change in the distance between the electrodes at regular time intervals, determining the tendency of the energy consumption change then taking place, and controlling the anode position in relation to this tendency, until the slope of this tendency, following an arbitrary distance adjustment, becomes nil. The method is used in the electrolysis of aluminium to reach minimum energy consumption under the operation conditions obtaining at any one time. The total energy consumption during the electrolysis of aluminium is composed of the electrical power used and the additional energy supplied by the anode carbon.

Title: Weft length control - by stud on coupling disc operating with selection disc limits
Inventor: HODR MILOSLAV
IPC: D03D47/26

Title: Operation of laundry-unit for oil-soiled machine-cloths - by re-using water in counter-flow and treatment in oil-separator
Inventor: REIMANN KURT
IPC: D06F31/00
Filed: 1973-08-23
Abstract: The process for operating the laundry for cloths used in cleaning machines provides for the use of a drum washing machine with a washing-compartment in a stationary outer drum and a perforated washing-drum, revolving inside the latter. A stepwise counterflow process with several washing and rinsing steps is used. Clean water is used for the last rinsing step and this amount of water is used for the respective preceding rinsing or washing step of the subsequent washing cycle. After completion of the operation, it is passed to a reservoir and re-used for the next cycle, and, after completion of the first washing operation of a cycle, it is passed to an oil-separator, the oil being passed to an oil-burner, while the wash-liquid, freed from oil and further cleaned, is passed into the effluents. Centrifuging takes place between the washing and rinsing steps. The process has the advantages of economy in the use of water and avoidance of passing objectionable oils into the effluent system. The oil is used as fuel for running the plant.

Title: Sewing machine workpiece guide ensuring edge-parallel seams - without distortion of the fabric layers relatively to each other
Inventor: TRENTELMAN JULIUS GERARDUS
IPC: D05B35/10
Filed: 1973-12-21
Abstract: A guide for ensuring that seams are sewn parallel to the edges of the prodt. section, has a stop rail and means of moving the workpieces in the direction of the stop, including an uneven surface in the worktable zone in front of the feeder and presser foot. The unevenness of the surface on which the sections are laid, is formed by grooves or undulations running diagonally across the line of motion under the needle, towards the stop, and holding down plates having a complementary surface are provided. Because of the differing frictional and deformative action of the unevenness, differential forces opposed to those tending to pull the workpieces in a variety of directions, are set up, so that the resultant forces working against the sewing machine feeder subtend an angle to the line of motion, less than 180 degrees in the direction of the stop rail. No braking action of the section edges opposite to the stop, and no turning moment tending to distort the fabric.

Title: Wheel rim for tubeless tyre has annular humps - adjacent emergency running rings to give long travel when punctured
Inventor: PRUSS GUENTHER MANFRED
IPC: B60B21/10
Filed: 1974-04-18
Abstract: A wheel rim for a tubeless typre comprises annular humps towards the outer edge of the tyre and immediately adjacent to annular troughs, in which emergency running rings are seated; in normal running, the beadings bear against these humps, but if the tyre loses press., the outer walls roll over outwards so as to rest against the emergency rings, the beadings remaining in posn. against the humps. The side walls diverge radially inwards away from the tread region. Tubeless tyres without fabric reinforcement in the casing may be used, or alternatively tyres with continuous steel tread reinforcement. The tyre casing may be of plastics. when press. is lost, the tyre flattens somewhat radially inwards but rolls over onto the emergency running rings, so that steering control is onot lost and it is possible to drive the automobile a considerable distance on the tyre without damage to the tyre.
