Abstract: 1. A process for cleaning filter material of filters for the mechanical filtration of liquids, especially water, in which the liquid to be cleaned flows from above downwards through a filter vessel filled with filter material, while the filter material laden with soiling substances is successively removed from the filter vessel at its upper end, fed to a washing vessel, cleaned and then fed to the filter again at its lower end, characterized in that a filter material is used which is of lower specific gravity than the liquid, in that the soiled filter material is conveyed, by reason of the pressure difference present between filter vessel and washing vessel, from the filter vessel into the washing vessel and in that the cleaned filter material is conducted back by means of buoyancy forces from the washing vessel arranged beneath the filter vessel, into the filter vessel.

Abstract: @ A method of producing a modulated chrominance signal with suppressed carrier. A square-wave carrier signal and a colour information signal in the form of a sequence of digitally encloded amplitude values are applied to a modulator arrangement. The clock frequency for the amplitude values is an integral multiple of the colour carrier frequency and is phase-locked thereto. Each bit of the amplitude values is inverted during one half cycle of the carrier and not inverted in the subsequent half cycle. A first and a second value, respectively are added to the values obtained thus, these first and second values being calculated such that also for input and/or output signal values which are located at a distance from the drive mean values at the input and output ends a total carrier suppression is achieved for the desired input signal level. The modulated analog chrominance signal is available after digital-to-analog conversion.

Abstract: A braided preform fabrication for annular refractory articles such as an integral monolithic throat section (33) and exit cone (34) of a rocket motor nozzle is formed on a mandrel (10) and includes closely spaced radially oriented carbon rods (12) that extend to a uniform length from the mandrel surface and carbon fibers (17,18,19) braided on the surface of the mandrel around the carbon rods in a triaxial braid whereby the fabrication has a 4-D fiber architecture. The density of the fabrication is increased by a process that is repeated four times and involves the steps of vacuum impregnation thereof with pitch, subjecting the impregnated preform (25) to high pressure at a temperature that is gradually increased to about 700°C to convert the pitch to coke and to form the braided preform and mandrel into a billet (31), and producing graphitization of the braided preform by subjecting the billet to an argon atmosphere in a vacuum furnace at a temperature that is gradually increased to 2,500°C. The mandrel (10) is usually removed from the billet (31) by machining after the second repetition of the process, but it may be removed at any time after the braided preform structure (25) has acquired sufficient strength to withstand the temperature and pressure of further processing.

Abstract: A separator comprises a vessel having an outer wall (2) and an end wall (3). A body (14) adjacent the end wall (3) defines with the end wall (3) an annular opening (15). In use, a mixture of, for example water and solid material is introduced into the vessel through a first inlet (4). A circulating motion takes place in the vessel and the solid material falls to the end wall (3) and is removed through the opening (15) to an outlet (6) while clean water flows from the top of the vessel through an outlet (8). In order to increase the energy in the lower region of the vessel so as to assist removal of the solid material, water from the outlet (8) is passed through a pump (P) and reintroduced as energising fluid to the vessel through a recirculating port (44). Energising fluid may be taken from sources other than the outlet (8). Various alternative forms of separator are disclosed.

Then the antifreeze liquid is heated to an enzymatic cycling reaction temperature so as to perform the enzymatic cycling reaction simultaneously for liquids contained in all the reaction vessels for a desired period. Then, the antifreeze liquid is heated to a high temperature so as to stop simultaneously the cycling reaction in all the reaction vessels.

Abstract: A filter for molten metal prior to casting in a mold has a plurality of ceramic elements in contact with each other, each element (11) having numerous apertures, e.g. slots (13) separated by ribs (12), and the contacting portions (14) of the elements are arranged, so that the apertures (13) of adjacent elements are staggered so that the metal flowing out of one aperture passes through the space (16) between adjacent elements before flowing through aperture of the next element; thus fine filtration is achieved. 
     The distance (H) between the ribs of different elements is preferably less through the widths (W) of the aperture, e.g. H < 0.8 mm. 
     The elements may be flat plates rectangular in shape (Figs 1-3) or circular (Fig 4); orfrustro-conical (Figs 10-11) or tubular (Fig 13); in the latter cases they nest one inside each other. The apertures may be rows of circular holes (Fig 21-22). Successive elements may be identical or non- identical as regards their arrangement and size of apertures. 
     Elements can be made by injection molding and sintering of a ceramic, e.g. silica, and a binder; preferably they are microporous.
