A sanitation system for treating a black water stream and a grey water stream. The black water stream is inputted into a black water digester wherein the black water stream is aerobically digested to produce a treated black water stream and the treated black water stream is discharged from the black water digester. The treated black water stream is inputted into a black and grey water digester and...

2087601 9202647 PCTABS00010 A method of controlling product quality in a conversion of reactor feed to an iron carbide-containing product in a fluidized bed reactor (16). A Mossbauer analysis is performed (18) on product samples leaving the fluidized bed reactor (16), and a regression analysis is performed on the Mossbauer data. Depending upon the results of the regression analysis, process parame...

A process for controlling the conversion of reactor feed to iron carbide is disclosed. The reactor feed is subjected to a pro- cess gas in a fluidized bed reactor (10), and measurements (56) are taken of individual gases in the off-gas from this reaction and the temperature (64) and pressure (66). A stability phase diagram is generat ed based on the temperature. Different regions of the stability...

For protection against oxidation or other adverse chemical deterioration, substrates such as carbon, intermetallic aluminides, and refractory metal alloys are provided with barrier coatings of an aluminoborate glassceramic coating having a composition, in weight percent, of about 10-55% Al2O3, 4-40% B2O3, up to 70% total of RO, wherein RO consists of one or more alkaline earth metal oxides selecte...

An optical system for producing a high power light source comprises a number of laser diodes, or similar sources, which emit light from an emission stripe (8) having a long dimension a (x-axis) an d a short dimension b (y-axis) and which have a high- er numerical aperture in the y-axis than in the x-axis. The laser beams (9) are collimated by a lens (10) and focused onto an opti- cal fibre by a f...

Mechanism for the conversion of a linear motion of a first element to a rotary motion of a second element, using a flexible pulling element (2) such as a chain or cord as the first element and a shaft (19) to be adjusted as the second element, said pulling element (2) mating with the outer periphery of a roller (1) connected to the shaft (19) to be adjusted. A rattling slip coupling (18) is placed...

2088479 9203021 PCTABS00010 A decoder screen (80) is intended for use in an imaging system in which the screen is disposed between a viewer and a composite image containing alternate portions of two images which together form a stereoscopic pair. The decoder screen (80) includes a surface on which is printed a pattern of alternating clear and opaque areas, for example, parallel stripes or a cheque...

In a method of encoding and decoding informational data for transmission to a storage medium, a group G of physical blocks written to the storage medium includes both user data information blocks and auxiliary error correction blocks. Each block (Br,c) included in the group G belongs both to a row r and a column c. Informational data is formatted into preselected bit positions of the user data inf...

Cross-shaped blade turner that exposes one blade at a time to the work. A lever precedes the blade and on impact with the obstacle disengages it, allowing another blade to take its place, which in turn is held in the working position when the said lever has passed the obstacle.

The invention relates to a cutting bench for glass sheets with a fixed modular platform of self-supporting preassembled and equipped box panels and incorporated loading arms with an obtuse tilt equipped with integral loading devices.

The removal of the pyrite from finely divided coal with a high pyritic sulphur content is effected by a process which comprises modifying the hydrophilicity of the pyrite in a time period of less than 5 minutes by the use of suitable cells of Sulfolobus and separating the thus modified pyrite from the particles of coal by agglomeration or flotation techniques. This process makes it possible to obt...

A volumetric meter for liquids and/or gases in which rolling rollers are mutually repelled magnetically to press in a sealed manner against the inner surface of the outer casing of the meter, said rollers being housed in circumferential grooves in the rotor, which is mounted eccentric to said outer casing, said grooves being inclined forwards to the direction of rotation of the rotor.

A catalyst is described for the preparation of isobutene by dehydroisomerization of n-butane consisting of a solid, granular support of porous gamma-alumina on the surface of which catalytic quantities of platinum, silica and preferably also one or more promotors are deposited. In a preferred form of embodiment this catalyst is used with a second catalyst which may be formed of Boralite B or a sol...

Process for oxidating paraffinic compounds into their corresponding alcoholic and/or ketonic derivatives, which process consists in causing said paraffins to react, at a temperature comprised within the range of from 0 DEG C to 100 DEG C, preferably in an acidic medium, with a mixture of oxygen and hydrogen, in the presence of a catalyst on the basis of titanium-silicalite and of a noble metal and...

The skein end of the thread (1) to be used for rejoining in an open-end spinning machine is first picked up and from it the probably defective end is removed along a set length, controlling the operation with a pick-up sensor (15), and then its end rid of the defective section is prepared.
