The claimed process is performed either as a continuous duty process, or discontinuously, by mixing the deuterium-depleted water with a mineral substances concentrated water, in a determined ratio, followed by saturating the aqueous mixture with oxygen by sparging with dry air at the ambient temperature.

Title: Tight device for under-pressure boring metal pipes
Inventor: POPESCU TEODOR COSTINEL
IPC: B23B41/08
Filed: 2007-02-14
Abstract: The invention relates to a device allowing the boring of some metal pipes under pressure which are components of a potable, industrial or heating water distribution network. According to the invention, the device is mounted in a ball check valve (4) screwed into a threaded connection (1) welded on the external outline and normal to the axis of a pipe to be bored with a cutting tool (2) having a rotation motion generated by a portable boring machine coupled to a driving rod (5) which, in its turn, is coupled to a rod (3) secured to the tool, as well as an axial advance motion generated by a screw-nut mechanism consisting of a mobile rod (6) and a hand-actuated driving wheel (8).

Title: Process for preparing composites with oriented properties and composite product obtained thereby
Inventor: LUNGU DĂIAN-HORAŢIU
IPC: C22C49/08
Filed: 2010-10-22
Abstract: The invention relates to composite materials with oriented properties and to a process for preparing said composites which are intended to be used for replacing steel, bronze and brass in the process of manufacturing machine parts, such as bushings, discs or toothed wheels, due to their increased wear and oxidation resistance and their capacity of functioning at temperatures of up to 1000°C. According to the invention, the composite materials comprise an amount of 91...50% oxidic ceramic materials and metal carbides as powders which represent the composite matrix, an amount of 8...48.5% steel powder or fibres with a Length/Diameter ratio < 20, as a reinforcing material, together with 1...1.5% zinc stearate or paraffin, where the composite materials have the following properties: density ρ = 2740...3000 kg/m, compactness C = 84...96%, porosity P = 4...16% and gravimetric wear ranging between 0.09...0.11 g. The process claimed by the invention consists of an oriented arrangement of steel powders and fibres contained within the matrix by applying thereto a magnetic field generated by a coil supplied from a D.C source and comprises the following operation sequence: filling of the mould (), application of the magnetic field and vibration (), compaction () at pressures ranging between 400...600 MPa by unilateral, bilateral, isostatic pressing or by vibration pressing, extraction of the compacted material (), sintering it under nitrogen atmosphere or under vacuum, at a temperature of 400°C to eliminate the lubricants, the last operation consisting in increasing the temperature up to T = 1050...1100°C and maintaining it for 1.5...3 h.

Title: Composite materials of magnetic cluster type covered with multiple inorganic layers
Inventor: PETRAN ANCA CRISTINA
IPC: C09D11/00
Filed: 2015-12-11
Abstract: The invention relates to a process for preparing a magnetic composite material for manufacturing security materials. According to the invention, the process consists in the synthesis of some magnetic clusters which are covered with a first inorganic layer of barium sulphate, after which they are subjected to a reaction with tetraethyl orthosilicate in admixture with ethanol, water and ammonia, at the room temperature, for 3 h, while continuously magnetically stirring, the resulting particles are magnetically separated, washed and dried, resulting in a composite material of cluster-type covered with double inorganic layer of FeO/BaSO/SiO-type, with a saturation magnetization value Ms of 20 emu/g.

Title: Single –action convertible utility knife and scraper
Inventor: JOSHUA KEELER
Filed: 2020-06-21
Abstract: A single-action convertible utility knife and scraper includes a carriage and a slide mechanism slidably mounted within a housing. A blade support is pivotally mounted on the carriage for movements of a blade between cutting and scraper orientations. The carriage and the slide mechanism can be moved by an external button between a retracted position wherein the blade support is fully retracted within the housing, an extended position wherein the blade support is in an operative cutting or scraping position and a conversion position wherein the blade support is moved forwardly of the extended position to enable the blade support to transition from one orientation to another while clearing the housing. A bi-stable mechanism alternatingly pivots the blade support between the first and second orientations when the external button is successively advanced to move the slide mechanism forwardly beyond the extended position to incrementally advanced positions Fig 1
