Abstract: An apparatus is described for heating oil for an internal-combustion engine. The apparatus includes a heat-exchanger arranged within an oil sump of the internal-combustion engine, which is flowed through or capable of being flowed through by a thermal medium for the purpose of emitting heat to oil in the oil sump. The apparatus further includes a heat-source in fluidic communication with the heat-exchanger, which is designed to heat the thermal medium outside the oil sump and outside the internal-combustion engine.

Abstract: Peritoneal dialysis device (10) with a balancing chamber (28), which is divided into two balancing chamber halves (32 and 34) by a membrane (30), with an introduction line arrangement (16, 20, 22, 24), a discharge arrangement (22, 24, 20, 62), a catheter line arrangement (36, 38, 42), a valve arrangement (46-52), a pump arrangement (60, 108, 110) and a control unit (82), which switches the balancing chamber halves (32 and 34) in the filling or emptying operation with the aid of the valve arrangement (46-52).The peritoneal dialysis device (10, 106) operates under pressure monitoring volumetrically in the filling phase and pressure-controlled in the emptying phase, and determines the volume of dialysis fluid introduced or discharged from the number of balancing chamber strokes and the ultrafiltration volume from the difference of these.

Abstract: In order to work up pyrotechnical material, I. the pyrotechnical material is burned in a controlled manner, the slag is optionally allowed to continue reacting and the crude gas formed is passed through a high-temperature region in which the gas is exposed to a temperature of at least 1200.degree. C. over a predetermined period in order to decompose organic substances still present; II. the crude gas formed during the combustion is cooled to a temperature below 400.degree. C.; III. the crude gas is purified under dry conditions by first feeding it into a preliminary separator, coarse particles being separated off, and then feeding the crude gas via fine dust filters in order to separate off finely divided solids and/or IV. the crude gas is optionally purified under wet conditions by first passing it through a rotary scrubber and then passing it via one or more absorption units and V. the purified gas is released as waste air.

Abstract: A method of producing a finely structured body which includes a plurality of stacked, cut sections of foil at least one of which is provided with grooves in a selected groove direction on at least one surface thereof, and which has a plurality of closely juxtaposed, channel-like perforations with high shape accuracy, true dimensions and high surface quality. The method includes: a. providing a vacuum clamping means comprised of a ground, sintered metal plate which is connected to a vacuum source and which is positioned on a work table which is movable in two mutually perpendicular directions X and Y; b. positioning a machinable foil on the ground, sintered metal plate and clamping the machinable foil thereto by applying an effective amount of vacuum; c.

Abstract: A method of producing a finely structured body comprised of a plurality of stacked, cut sections of foil at least one of which is provided with grooves. A machinable foil is wrapped around a cylindrical mandrel of a lathe to overlap opposing edges. The overlapped edges are clamped into an axial recess of the cylindrical mandrel by means of a clamping means and a plurality of grooves cut into the surface of the foil by means of at least one shaping diamond positioned in a feed which is finely adjustable. The plurality of grooves each have a groove length, a groove width, and a cross-sectional shape that is constant over the groove length and is freely selectable. Then, the grooved machinable foil is cut into cut sectoins and the cut sections are stacked. The plurality of grooves have a form precision such that, for groove lengths of more than 1000 .mu.m, the groove width has an accuracy of about .+-.1 .mu.m for land widths which equal or exceed about 15 .mu.m.

Abstract: A process and apparatus for leak-proof sealing of a metallic capsule closed by a stopper and joining the capsule to a metal cable by arc welding, wherein a capacitor is charged, the capsule with a striking tip at one end or the stopper with an ignition point and the cable are clamped at their ends, connected to the terminals of the capacitor, moved together and welded together by discharging of the capacitor with the formation of an arc.

Abstract: An apparatus for electrodepositing a layer of predetermined layer thickness has an anode supplied with DC voltage by a converter device. A programmable computer having inputs for the desired value of the layer thickness and for technological parameters, such as anode index and area factor, cyclically sums the current charge as the integral of current from digitized sampling values of the anodes current and determines therefrom the actual value of the layer thickness. When the desired thickness value is reached, the converter device is disconnected.
