Title: Controlling sheet metal deep drawing operation - by continuously adjusting pressure on holding-down ring
Inventor: HIPP THOMAS DR
IPC: B21D24/14
Filed: 1990-12-01
Abstract: The cylindrical container is produced from a sheet metal blank by deep drawing. The blank (15) is held in place by the holding down ring (3) which presses the balnk against the deep drawing ring (2). This force is exerted by a hydraulic cylinder (11) and is set initially at an estimated value so that the friction between the holding down ring (2) corresponds to the tangential force exerted on the blank by the drawing operation. If the holding down force is insufficient the blank tends to pucker so that the gap between the holding down ring (3) and deep drawing ring (2) increases. This increase in gap width is sensed by the electro-optical device (5) which controls the system so that the hydraulic pressure is increased. USE - Deep drawing sheet metal workpieces.

Patent DE-4218958-A1 (DE)
Inventor: ENNEN GUENTHER DR
IPC: D06F39/00
Filed: 1992-06-10
Abstract: In a process for reusing rinsing or cleaning liquid in program-controlled dishwashers or washing-machines, wherein the soiled liquid, which is pumped off out of the washing container at the end of a water-conducting rinsing or washing phase with/without heating of the water, is cleaned, if appropriate temporarily stored, and returned to the washing container in a subsequent rinsing or washing phase, provision is made for a partial quantity of liquid (F1) up to a calculable quantity of residual water (F2) from the available rinsing liquid (S), pumped off from one or more rinsing phases or rinsing programs, to be subjected to filtration for reusing the rinsing water, and for the unfiltered quantity of residual water (F2), remaining at the end of filtration with an increased concentration of the quantity of dirt, to be evaporated, liquified and subsequently added to the filtered rinsing liquid or to be used separately for a subsequent rinsing phase. By means of such a measure, the consumption of fresh water can advantageously be drastically reduced in relation to the previously known water-saving methods without adversely affecting the cleaning performance, and energy-saving operation can be achieved. The heating energy required for evaporating the quantity of residual water is returned to the rinsing water such that virtually no heating energy is lost. The process is also harmless to the environment since only dried filtrate remains from the cleaned rinsing or washing solution, which filtrate can be disposed of without problems in the domestic refuse. <IMAGE>

ADVANTAGE - Provides a de-oxidising current of approx. 6 mA to auxiliary contacts to remove effects of long periods of inoperation i.e. open condition. Opto-coupler ensures isolation of signal circuits from mains voltage and low impedance AC circuit suppresses effects of transients. Is suitable for long lines and low power consumption enables small low-cost construction.
