Inventor: PIATTELLI RAFFAELE
Filed: 1990-11-02
Granted: 1994-09-12
Abstract: Process for the purification of effluent waters (so- called "percolates") from dumps of solid urban wastes, comprising the stages of taking the percolate from a sedimentation and holding tank, and passing it to one or more concentration and distillation stages at the outlet of which two streams are obtained, namely: - a highly concentrated residue which contains almost all the original pollutant burden and is rendered solid and harmless by inertization based on silicates and cement; - a distillate which after neutralization of the pH is subjected to an activated sludge biological oxidation treatment also comprising the stages of nitrification and denitrification of the ammonia; at the outlet from this stage, purified water, in the sense of the current legislation, and which is reutilizable, is obtained. <IMAGE>

Title: Casting mould for automatic rotor conveyer
Inventor: OZERSKIS MECISLAVS
IPC: B29C45/26
Filed: 1994-02-25
Abstract: The goal of the invention is to ensure moulding of complex form details with axial and radial holes and to increase the safety of the mould.The proposed mould (Fig.1) consists of an upper and a lower part, which have been positioned respectively on the lower and upper transporter chains of the automated rotor - conveyor. The upper part of the mould contains the upper housing, a multi - spaced matrix and the large core with markings for producing radial holes in the manufactured details. The large core is mobile for the removal of details, moulded in the central drill hole of the upper part from the matrix, so that they should be in reach of a remover of ready details from the automated rotor - conveyer. The lower part of the mould has a lower housing and several punches with small cores for the production of axial holes in the manufactured details. Each small core is based on an elastic element, positioned on the surface of the lower housing, in order to achieve safe contact between the small core and the marking of the large core, and thus to ensure confluence of the axial and radial holes in the manufactured details.<IMAGE>

Title: Endoscope with single-use cartridge for invagination of endoscopic tube
Inventor: MATASOVS SERGEJS
IPC: A61B1/273
Filed: 1997-10-03
Abstract: The present invention pertains to the field of medicine. More precisely, it relates to an endoscope that comprises an invagination device in the shape of a tubular cylinder, wherein said cylinder is separated by a gap from the endoscopic tube and has an outer diameter with periodically narrowing sections as well as an inner diameter with periodically widening sections. The endoscope also includes a system of traction cables for bending the distal end of the endoscopic tube. This endoscope further includes a cartridge in the shape of a sleeve for receiving the condom of the distal part of the endoscopic tube as well as a spring. One end of the invagination device is turned inside out and is connected to the distal end of the sleeve which is covered with a seal, wherein said invagination device also includes an anal dilator and an endoscopic tube nozzle. The controllable flexible distal end of the endoscopic tube can be bent, e.g., by help of a table unit, control pedals and a mechanism for supplying the endoscopic tube, even when the endoscopic tube is sharply bent owing to the fact that the traction cables are arranged each in a small, longitudinally extensible tube. When one traction cable of a pair of traction cable is extended, a vacuum is pneumatically or hydraulically applied to the associated small tube and overpressure is applied to the small tube of the other traction cable of the pair of traction cables.

Title: Polymer compositions
Inventor: BUSH STEPHEN F
IPC: C08F299/04
Filed: 1988-12-27
Abstract: A thickened organic polymeric composition useful for molding and capable of resisting post-molding shrinkage after being cross-linked comprises a cross-linkable base resin dissolved in an unsaturated monomer, and an additive resin selected from saturated polyesters and saturated amide waxes, the additive resin being crystalline at ambient temperatures and having a melting point (Tm) below a temperature (Tc) at which the base resin cross-linking reaction proceeds at a significant rate. The base resin and additive resin have only a partial degree of compatibility. When cooled from a temperature between Tm and Tc to a temperature between Tm and ambient the composition thickens, whereas, when it is heated to a temperature below Tc, it reverts to a flowable composition.

Title: Filtering screen
Inventor: ROBERTSON GRAHAM
IPC: B07B1/46
Filed: 2004-04-07
Granted: 2005-08-03
Abstract: A method of manufacturing two screens in a jig by laying a length of woven wire cloth across two rectangular frames laid side by side in the jig with longer edges abutting, and orientating the cloth so that the warp wires extend continuously across the two screens. The cloth is tensioned and bonded to the frames after which it is severed along the join and surplus cloth is trimmed away from the edges of the frame. If the cloth has a square mesh and the warp wires are of greater cross-section than the weft wires, the warp wires will extend across the width of the frame, and if the cloth has a rectangular mesh, the greater number of warp wires per unit length also extends across the width of the frame. In each case warp wires will resist the stresses across the width of the central region of each opening.
