Abstract: Sea water is supplied in a constant or variable flow to a heat exchanger (3) and returned to the sea. A heat carrying medium is pumped simultaneously through the heat exchanger (3) and a supply conduit (7, 11) to an evaporator for a per se known heat pump (8) and through a return conduit (12, 9) again to the heat exchanger (3). The medium is pumped in a flow exceeding the flow through the evaporator, and a part of the medium is directed from the supply conduit (7) past (10) the evaporator and to the return conduit (9). The sea water flow is of a size at least equal to the medium flow.

Patent DE-3360031-D1 (DE)
Title: Method and apparatus for the biological purification of waste waters containing phosphate
Inventor: REIMANN HANS DR RER NAT
IPC: C02F1/24
Filed: 1983-02-17
Granted: 1985-01-31
Abstract: This invention relates to a process for the biological purification of phosphate-containing wastewater wherein the wastewater is gas-treated, i.e. aerated, in an oxygenation tank in the presence of activated sludge for degrading organic hydrocarbon compounds and absorption of phosphate by microorganisms present in the activated sludge. The wastewater-activated sludge mixture is then withdrawn from the oxygenated tank and divided, in a post clarification stage, into purified, essentially phosphate-free water and phosphate-containing sludge. The phosphate-containing sludge is recycled, at least in part, into the oxygenation tank. A partial stream of wastewater-activated sludge mixture is branched off from the oxygenation tank, and/or recycle sludge is branched off as a partial stream from the post clarification stage, and the mixture is subjected to flotation treatment for thickening. A thus-obtained, low-phosphate flotage, i.e. subnatant liquor, is discharged from the flotation unit. Likewise, resultant, phosphate-rich flotage sludge, i.e. thickened floating sludge, is discharged and heated, and after this heating, is treated anaerobically and mixed with wastewater to be purified. Subsequently, the wastewater-flotage sludge mixture is subjected to a phosphate separation and thus-produced, low-phosphate sludge is recycled into the oxygenation tank, and phosphate-enriched liquid is further treated.

Granted: 1988-10-20
Abstract: A Delta-Sigma modulator for one-bit analog to digital conversion of a signal (U(t)), such as a telephone voice channel signal to digital form is disclosed. The voice signal is sampled (1, 3, C<sub>1</sub>) at a rate high compared to the highest voice channel frequency component. Sampled instantaneous signal values are integrated (4, C<sub>3</sub>), re-sampled (10, 12, C<sub>4</sub>) and again integrated (17, C<sub>6</sub>) to reduce encoding noise. Finally, a bi-level sense identifying circuit (19) links the second integrator output to a D type flip-flop (20) providing the one-bit encoder output (b(n)).The sampling and integrator control is effected by switching in a capacitor charge shifting arrangement under clock control and feedback is applied as a capacitor switching program modification (301, 302).

Title: Flat wringing apparatus for mops
Inventor: SACKS DIETER
IPC: A47L13/146
Filed: 1985-10-15
Granted: 1989-07-06
Abstract: An apparatus for wringing the strands of mops has a housing which supports two lateral carriers for a set of horizontal wringing elements which are installed in the housing and are movable toward and away from the inner side of the front wall of the housing. The wringing elements are pivotable within limits about horizontal axes and have limited freedom of upward and downward movement relative to the lateral walls of the housing so that they can conform the orientation of their profiled front sides to the outlines of adjacent portions of a pile of strands which are introduced into the housing between the front wall and the wringing elements while the carriers maintain such elements in retracted positions. The carriers are formed with horizontal toothed racks mating with gear segments which are rotatably mounted in the housing and can be rotated by a pivotable lever so as to move the carriers and the wringing elements toward or away from the front wall. The end portions of the wringing elements have followers which extend through horizontal slots in the lateral walls of the housing and into bearings provided on the two carriers.

Abstract: An apparatus for sharpening knives, and the like where fixed abrasive elements on an orbiting surface in contact with the knife cutting edge facet move in a mechanically generated uniform cyclic orbit of circumference less than about one (1) inch and through that motion provides the work and energy to sharpen the knife or blade edge. The apparatus provides a circumferential velocity of the abrasive element of less than 800 feet per minute and restrains motion of the abrasive surface to less than ± .005 inch in a direction perpendicularto the intended plane of the knife or knife edge facet. The apparatus contains novel magnetic and other means to steady, guide and control position and angle of the face of the blade relative to the orbiting abrasive elements, to realign any burr or sharpening debris on the knife edge, to control in part the abrading forces, and to remove sharpening debris from the abrasive surface and sharpening zone. A means used to create the orbital motion of the abrasive surface utilizes a pair of synchronously driven eccentric cranks that engage an orbiting drive plate that supports the abrasive surface or surfaces, where the eccentric cranks are mounted on or are an integral part of the shafts of two gear pulleys driven syncronously by means of a motor-driven timing belt, and where the supporting drive plate is constrained to orbit in a prescribed principal plane by means of fixed bearing support points.
