Title: Receptacle for live fish
Inventor: KONG KYONG-SOK
IPC: A01K63/04
Filed: 1991-01-16
Granted: 1992-11-09
Abstract: In the aquarium, fish excrement and other solids pass through the porous bottom  plate  to  be  collected  in  a  funnal  shaped collector to flow through the drain in the center  to  a  pressure filter, which filters the solid waste for the filtered clean water to be resupplied with a pump through a heater or a coller for  the proper temperature adjustment to  the  water  supply  pipe  to  be discharged from a nozzle. The discharging water  from  the  nozzle draws ozone from an ozone generater through its feed pipe with the discharge pressure of water to generate fine bubbles of ozone.  An air pump supplies air through a discharger in the  center  of  the tank and an air feed pipe provided  around  the  tank  bottom  and perforated for air  pores  to  generate  bubbles  including  ozone supplied through  the  air  pump  from  the  ozone  generator  the sterilize the water on the way up. Infrared lights and fluorescent lights are provided on the top inner side of  the  tank  for  good illumination.

CONSTITUTION: The method comprises the steps of (i) dissolving one compound selected from polyphenols in a mixture of excess equivalent of epichlorohydrin with respect to phenolic hydroxyl group and 0.5-30 wt.% of polar solvent with respect to the epichlorohydrin; (ii) adding water to the solvent mixture so that water content in the solvent mixture is maintained to 0.1-4.0 wt.%; (iii) introducing 0.95-1.05 equivalent of solid alkaline metal hydroxide with respect to 1 equivalent of the phenolic hydroxyl group for 30-180 minutes continuously or divisionally while the temperature is maintained to 40-80 deg.C; (iv) aging the resulting blend for 10-120 minutes in the condition as above to effect an epoxidation; (v) adding water to the product resulting from the epoxidation in the presence of excess of epichlorohydrin to remove product salt and by-product from the product, and then recovering the excess of epichlorohydrin by distillation and dissolving the epichlorohydrin to inert organic solvent, or recovering the excess of epichlorohydrin by distillation and then adding water to the product resulting from the epoxization(which is dissolved in inert organic solvent) to remove product salt and by-product; (vi) purifying the product from the step(v) using 20-50 wt.% of aqueous solution of 1-10 equivalent of alkali metal hydroxide with respect to 1 equivalent of chlorine contained in the product.

Abstract: The invention relates to a die for producing a sanitary article through thermal formation, and to a process for carrying out the same. According to the invention, the die includes a first wear layer (b) and more base layers (b1, b2 ....) wherein there are embedded some reinforcements consisting of a metal net (2) and/or a glass fibre felting (3) and some air networks (4), some cooling water networks (5) as well as a frame (6) for securing to the thermally forming machine, the air network (4) being provided with some orifices (f) for the air circulation, arranged towards the active face (d) of the die. According to the invention, the process for carrying out the die consists in applying, on the active surface (a) of a last (1) representing the negative of the main surface of said product, first a primary layer consisting of a stripping material containing wax and polyvinyl alcohol, with a thickness of 1 mm at the most, then a wear or surface layer (b) containing metal powder and epoxy resin with or without graphite powder, followed by one or more base layers (b1, b2 ...) embedding some reinforcing elements (2, 3, 4, 5 and 6) into the composition mass that no longer contains graphite, but only metal powder, depending on the volume and final rigidity of the product to be obtained.

Title: Ecological intake of desilted water from rapid mountain river stream beds

IPC: E02B8/02
Filed: 2006-10-31
Abstract: The invention relates to an ecological intake of water free of mechanical impurities resulting from the rapid mountain river stream beds. According to the invention, the intake comprises three main parts, namely an upstream sill (1) playing the role of taking over the water from the river natural stream bed and directing it towards a harnessed stream bed, a downstream sill (2) playing the role of taking over the water from the intake and directing it towards the user, giving the river the returned flow and eliminating the discharge of solids, and a connection channel (3) between the upstream sill (1) and the downstream sill (2) playing the role of taking over the water from the upstream sill (1) and of directing it on a stage (I), of allowing the passage thereof from one stage (I) to another stage (II) with an initial roughing, of permitting the returned flow to pass over the downstream sill (2), of performing the dynamic exclusion of the sediment from the water of the last stage (II) with continuous washing and of delivering it without sediments to the user through the downstream sill (2).
