Patent EP-0010338-A1 (EP)
Inventor: TER BEEK GERRIT JAN
IPC: B01D29/00
Filed: 1979-10-17
Abstract: A filter for filtering viscous liquids and particularly molten synthetic resins comprising a house (1,2) with an inletport (3), an outlet port (4) and a chamber defined therein having an inner surface (6) which is partly shaped as a revolutional surface. The chamber accomodates a concentric smooth straped revolutional body (7) while defining an annular slit (8) between said body and the house, through shich slit the material to be filtered is to be passed. The smooth shape of the body prevents congestion of the hot resins and any thermal degradation.

IPC: C07C27/00

Abstract: This invention relates to a process for purifying crude ethanol, whether produced by fermentation or by the synthetic route, to produce a pure ethanol-water azeotrope. The process uses only two distillation columns for fermentation ethanol and only three columns for synthetic ethanol because the latter has diethyl ether as impurity. The inventive concept lies in the design and specification of the columns and the specific distillation conditions which enable each of the impurities in ethanol to be reduced below 1 ppm. Ethanol of such purity is most desirable when used for potable or pharmaceutical purposes.

Abstract: The filter arrangement for an X-ray apparatus contains an X-ray source (2) for emitting a diverging beam (4) of X-rays and a filter plate (14) positioned in the beam of X-rays. The beam is symmetrical with respect to a center beam axis (8). The filter plate which serves for attenuation of the X-rays before they impinge on a target (16) is mounted on a pivoting axis (17). The pivoting axis is preferably arranged remote from and transverse to the center beam axis. By pivoting the filter plate (14) about the pivoting axis (17) into a selected position, a selected radiation profile can be obtained on the target (16). The rotatable filter plate (14) can thus replace a plurality of wedge filters.

Abstract: Assigned to the device for applying a medium is a limited space extending over the operating width which is located before the application region of the application device. This limited space is arranged above a screen which can also be constructed as a template. The limited space extends beyond the height of the application device and has a filling region which rises above the height of the application device and is closed off and/or sealed off from the application device by a wall. At least one feed device for pouring in a medium is assigned to this space. Various liquid, pasty or viscous chemicals, in particular foam containing application chemicals, can be introduced into this region. By this means, relatively small baths can be distributed onto a surface over the operating width in order to introduce them evenly onto or into a substrate. The foam is generally completely or partially destroyed in the screen area and then passes as a bath onto or into the surface structure. This can take place over a full or partial area. <IMAGE>

Abstract: A control system for a hydrostatic power transmission having a variable displacement hydraulic pump (2) and a hydraulic actuator (3) connected in a closed or semi-closed circuit, and means (2a, 10) for adjusting the displacement of the pump or the delivery thereby in accordance with a manipulated variable of an operating lever (13). The manipulated variable of the operating lever (13) is sensed by a sensor (14) which produces a signal (X L ) indicative thereof, an actual displacement of the pump (2) is sensed by a detector (2b) which produces a signal (Y) indicative thereof, and circuit pressures on the delivery and suction sides of the pump are sensed by sensors (15a, 15b) which produce signals (Pa, Pb) indicative thereof. A control unit (16) has a calculating circuit (17) operative to calculate a hydraulic pump displacement command (X) on the basis of the manipulated variable signal (X L ) and the circuit pressure signals (Pa, Pb) in such a manner that when the delivery side circuit pressure is higher than the suction side circuit pressure, the displacement is controlled in accordance with the manipulated variable while the rate of change in the displacement is controlled in such a manner that a variable cut-off pressure (Pc) which may vary depending on the manipulated variable is established with respect to the delivery side circuit pressure, and when the suction side circuit pressure is higher than the delivery side circuit pressure, the displacement is controlled in accordance with the manipulated variable while the rate of change in the displacement is controlled in such a manner that a cut-off pressure (Pc) which is constant regardless of the manipulated variable is established with respect to the suction side circuit pressure. The control unit (16) compares the command (X) with the actual displacement signal (Y) to generate a signal (i) for minimizing the difference therebetween and supply the signal (i) to the displacement adjusting means (10).

Abstract: In apparatus and a process for dissipating waste heat, e.g. from an electricity-generating plant, and at the same time removing dissolved solids from water, heat is transferred from the plant to liquid in a high temperature liquid circuit (11a) which exchanges heat with water in a lower temperature circuit (35a, 42, 35b) in which the dissolved solids are brought to a condition of super-saturation in a forced-draught cooling tower (56). The super-saturated water is then seeded with nuclei crystals and passed into a crystallizer (42), from which liquid is decanted and crystalline solids removed. Further solids-containing water is added to make up the decanted water for recirculation through the cooling tower. The need to dispose of heated and otherwise polluted water into the environment is avoided, and indeed industrially polluted water can be used in the process.

Abstract: Cathode material is provided for use in an electrolyte cell having an active metal anode and a compatible electrolyte. The cathode material is iron-rich iron sulphide of the general composition Fe (x  +  1)  where x is between 0.05 and 0.2 and is substantially devoid of sulphur-rich phases. The cathode material can be made by heating at 600°C a mixture of iron with iron sulphide and/or sulphur in the correct proportions to give the desired composition. An example of a cell in which the cathode material can be used is Li/a molar solution of LiAsF 6  in a mixture of 50% propylene carbonate and 50% dimethoxyethane/Fe 1.2 S. The use of the cathode material in a cell gives rise to a stable voltage when the cell is first connected in an electronic circuit.
