Patent DE-3670780-D1 (DE)
IPC: B23Q1/38

Abstract: In a process for edging metal strips, especially nonferrous metal strips, by means of an edging machine wherein the longitudinally driven metal strip is guided between an upper and a lower linear guide and cutting tools are disposed successively along the line of movement of the strip, on either side of the linear guides. It is proposed according to the invention that a liquid or gaseous fluid be forced out of the central part of the linear guides at individual points along the line of movement, into the clearance between the metal strip and the linear guides. In a linear guide for carrying out this process, provision is made according to the invention such that, in each linear guide face confronting the metal strip, there are a series of grooves running longitudinally along the center of the guide, the grooves being separate from one another and connected to inlets for the fluid. These measures assure, by means of the pressure cushion that forms in operation, that the friction and hence the driving force becomes extremely low, that the chips produced from the material are reliably kept out of the area between the linear guide tracks and the metal strip, and that the surfaces of the metal strip are protected against damage.

Abstract: A process for removing sulfur and ash from coal and other carbonaceous materials involving treating an aqueous slurry of coal or other carbonaceous materials at an elevated temperature below the oxidation temperature of the coal or other carbonaceous materials in the presence of an oxidizing agent capable of reducing pyritic sulfides to a soluble state with: (A) an alkaline earth metal and/or alkali metal chloride, a catalyst comprising one or more deliquescent halogen compounds, barium chloride, potassium chloride or mixtures thereof, and one or more reducing oxides, chromate salts or mixtures thereof, and an inorganic acid, or (B) a formulation comprising one or more hypochlorites and the above-described catalyst or catalyst and acid. Sulfur is extracted as sulfate or other soluble sulfurs. In a second embodiment, elemental sulfur may be extracted intermediate to producing sulfate and other soluble sulfur by treating an aqueous slurry of the coal or other carbonaceous materials at an elevated temperature below the oxidation temperature of the coal or other carbonaceous materials with an alkaline earth metal and/or alkali metal chloride and nitric acid. In the second embodiment, sulfur can be extracted as sulfate or other soluble sulfurs by using the process of the first embodiment or by treating the extracted solids with an alkaline earth metal and/or alkali metal chloride with an inorganic acid at an elevated temperature below the oxidation temperature of the coal or other carbonaceous materials in the presence of an oxidizing agent capable of reducing pyritic sulfides to a soluble state.

Abstract: A fast response, tubeless vacuum aspiration collection cassette includes large and small containers (30, 31) defined within a cassette housing adapted to be removably secured to a surgical aspiration machine. A first wall of the cassette housing abutting the machine includes connectors (58 and 68, 71) thereto to provide a controlled variable vacuum level to the small container (30), and a fixed vacuum level to the large container (31). The channels (47, 57, 42, 44 and 42, 61, 66) and valves (43, 46 and 62) are arranged so that when the containers (30, 31) are isolated by a first valve (62), the controlled vacuum level may be applied to the surgical probe through a second valve (43, 46) connecting it to the small container volume (30). Whenever the controlled vacuum is shut off to the probe by the second valve (43, 46) the first valve (62) is opened to permit the fixed vacuum in the larger container (31) to be applied to the smaller container (30) to transfer aspirant fluid therein to the larger container (31).

Abstract: For covering hitch balls on the hitch systems of cars a loose covering hood is usually used, which is placed over the hitch ball (6) and which may easily be lost if it is loose, or create noise if it is suspended in a chain, when the ball is being used. By the invention is provided a covering hood by means of two semi-spherical shells (24) which are pivotally fastened to the hitch rod (4) right below the hitch ball (6), such that they are pivotal from a covering position closed about the hitch ball to opposite projecting positions, in which the hitch ball is uncovered. On already existing hitch systems the shells (24) are easily mountable by means of a simple clamp fitting, which is even well suited to be fixed on a conical hitch ball rod.

Abstract: The outgoing gas or waste water is conveyed through a gas-liquid contact apparatus in which biological purification takes place. A bubble plate-type column (2) is used as gas-liquid contact apparatus. The biomass is distributed over the plates (3) in the form of an aqueous suspension with a layer height corresponding to a liquid content per plate greater than 0.07 m3/m2, preferably greater than 0.15 m3/m2 of column cross-section. During the biological purification of gas, the gas to be purified is supplied at the lower end of the bubble plate-type column (2). It then flows through the plates (3) and issues again as purified gas at the top of the plate column (2). When the plate column is used for purifying waste water, the waste water to be purified is conveyed from top to bottom through the plate column (2) and is traversed by air, oxygen or oxygen-containing gas. At the same time, a proportion of the biomass is separated from the purified waste water and re-circulated into the entering waste water or into the column. The waste water to be purified flows successively over the plates (3) to the liquid outlet (11). From here, the clarified waste water flows out through the overflow (13). This process is suitable, in particular, for highly charged waste water, particularly if a compact structure is required during construction of the apparatus.
