IPC: C02F9/00
Filed: 2002-04-15
Abstract: This publication describes a method for the purification of fish farming wastewater, which comprises three purification sub-units, which are swirl concentrator, drum screen and flotation. The fish farming wastewater (23) is first conveyed into a swirl concentrator (25), where the rougher solid matter is separated. The wastewater (28) passed through the swirl concentrator is then conveyed into a drum screen (29), where the final purification of the wastewater is accomplished. The drum screen has a dual function in the to purification system. First, the drum screen is used to recover the solid matter (sludge) that is not deposited in the swirl concentrator but would increase the discharge into the water system. Another function of the drum screen is to concentrate the sludge in an amount of water small enough to make it economically possible to clarify the wastewater by flotation to remove the sludge. The solid matter retained in the drum screen, i.e. the concentrated wastewater (32) is passed into a flotation stage (35), where the wastewater is cleaned of solid matter remaining in the concentrated wastewater. The sieve mesh size (43) of the drum screen determines the purification efficiency to be achieved. In the purification method, the swirl concentrator (25) can also be alternatively disposed after the drum screen (29). If the fish ponds and raceways of the fish farm are not self-cleaning, the swirl concen­trator will be superfluous and can be omitted. This purification method, being cheaper, can also be used for recovering the sludge produced in net bag farming.

[Also in Division H1] A dielectric material suitable for use in capacitors comprises metal particles insulated from each other the particles each having maximum dimensions of less than 200 A and the concentration of the particles being such that the dielectric constant of the material is greater than four. It is stated that metal particles of maximum dimension less than 200 A do not behave as metal when distributed in an insulating medium but have a polarizability so that the whole material has a high dielectric constant. Preferably the concentration of the particles is greater than 2 x 10<SP>12</SP> particles per cubic centimeter. The material may be manufactured by vacuum evaporation of alternately aluminium or copper and silicon monoxide on to a substrate, the rate of evaporation determining the particle size. Evaporation may be carried out in an oxidizing atmosphere so that each particle is surrounded by a coating of its oxide. Alternatively sputtering in an argon and oxygen atmosphere may be employed. In another method photosensitive glass containing about 1% of a gold or silver salt, 0.01 to 0À1% cerium oxide, at least 60% silica and 10 to 40% soda is irradiated with X-rays, #-rays or U.V. rays and annealed, the irradiation dose determining the number of metal particles and temperature and length of time of annealing the particle size. A metal halide e.g. sodium chloride may be irradiated with X-rays, U.V. light or an electron beam and heated to precipitate colloidal metal particles throughout the crystal, or, better, the halide crystals are heated in the vapour of the metal at about 450‹ C. and cooled slowly. Metal particles may also be incorporated in e.g. a metal halide by electro-diffusion using a gold or silver anode and a platinum cathode.

Abstract: 1,228,290. Reducing redundancy in video signals. WESTERN ELECTRIC CO. Inc. 22 Dec., 1969 [23 Dec., 1968], No. 62288/69. Heading H4F. In apparatus for reducing video signal redundancy including a frame memory 19 for storing an entire frame of video samples, a subtractor circuit 18 for determining the difference between a new video sample from camera 10 and a corresponding sample from a previous frame stored in the memory 19, and a control logic 2 for determining whether this difference exceeds a threshold level, the threshold level is arranged to be greater at high luminance levels than at low luminance levels. When, and only when, the difference exceeds the threshold level, the new video sample is fed into the frame memory 19 via a controlled switch circuit 29 to replace the original sample, and is also written into a buffer memory 28 for storage prior to subsequent synchronized read-out via transmitting apparatus 31. A forward-backward counter 27 determines the number of samples stored in the memory 28 and causes the threshold difference level to increase as the number of stored samples increases, as a protection against overflow of the buffer memory 28. The arrangement whereby the threshold difference level is greater at higher luminance levels includes a luminance weighting circuit 22 providing a signal Y which increases monotonically step-wise as the luminance level increases, and this signal is subtracted from the original difference signal X in a subtractor circuit 21. A negative overload 23 passes signals corresponding to positive values of X - Y unchanged to the control logic 25, but when Y> X the overload 23 provides an output corresponding to zero. An analogue-to-digital converter 12 enables the entire redundancy reduction procedure to be carried out in digital form.

Abstract: 1,252,504. Electric selective signalling. UNITED AIRCRAFT CORP. 3 Sept., 1969 [10 Sept., 1968], no. 43635/69. Heading G4H. A data detection and fault indicating apparatus includes a means for sensing a common data signal on a majority of input channels each carrying purportedly the same data signals and a device responsive to the sensing means for generating a fault signal in the absence of a common signal on all of the input channels. In a redundant data handling system wherein a number of data channels present digital manifestations of analogue data a number of converters, one for each channel, are provided for converting the digital manifestations to pulsewidth modulation manifestations which are passed through the above data detection and fault indicating apparatus. The generated fault signal is passed through a circuit, Fig. 3, which passes the signal only if it persists for a period of time longer than that which corresponds, on the same digital-pulsewidth scale used above, to the resolution of the A/D converters. Thus pseudo-errors corresponding only to differences in the digital manifestations of the analogue signal due to the lack of resolution of the converters are not signalled as errors.
