In two of the panels (1,2) the coatings are carried on separate sheets of float glass (5,9), one of the coatings 10 being an anti-abrasive coating is on the outermost surface of the glass (9) in the panel arrangement, while the other coating (6,7,8) being a relatively soft abra...

One-part organosiloxane composition curable by a platinum-catalyzed hydrosilation reaction contain the catalyst encapsulated within finely divided particles of a cured silicone rubber. The compositions are storage-stable for up to several days at room temperature, yet cure relatively rapidly when heated.

The invention relates to a biodegradable, single-phase starch/polymer mixture made from a starch moulding composition which comprises at least one chemically modified starch and at least one plasticizer or denaturing agent, and at least one selected linear polymer and optionally, in addition, additives customary in this area, and to the preparation thereof and to the use thereof for the production...

Nonwoven fabrics are described comprising a layered fabric having first layer of substantially thermoplastic material, for example Nylon 6 fibres, disposed adjacent and recessed bonded to at least one outer layer or a pair of outer layers of textile length fibres by means of heat and pressure. The thermoplastic fibres in the first layer have a lower melting point than the outer fibres in the fabri...

A method for forming a polyimide film on a substrate surface by chemical vapor deposition comprises evaporating an aromatic monomer compound having one amino group and two adjacent carboxyl groups or its derivative group, such as esters of 4-amino phthalic acid, and 4-(p-anilino) phthalic acid, thus a high strength polyimide is obtained represented by the general formula having its imide groups be...

A method of treatment of polluted emulsions or micro-emulsions (10) of oil in water, said method making use of tangential filtering through at least one membrane (1) constituted by a porous microfiltration structure which is constituted by titanium oxide, at least on the surface thereof. The method can be used to regenerate emulsions or micro-emulsions of oil in water.

An image signal representing a radiation image is detected from a recording medium which has been exposed to radiation over a limited irradiation field in order to record the radiation image thereon. From the image signal, a prospective contour point, which is considered to be present on a contour of the irradiation field, is detected. A method for judging the correctness or incorrectness of a pro...

The invention relates to a whole-body tanning device which can be produced in a particularly cost-effective way and can be operated at low cost, especially when used commercially. According to the invention, the tanning device has surface areas which are designed as uncovered areas and are mounted free of covering elements. The uncovered areas are provided in those surface areas which do not have ...

A method is provided for bridging between disjointed contour elements in an image by searching for an optimum bridging path between the facing ends of disjointed contour elements in the image. The method of the steps of defining a search window between each of the facing ends of the disjointed controur elements, considering in the window the different image points as nodes on a graph, determining ...

The sealing strip is for fire-protection purposes, being of fire-restricting material foam when fire breaks out. A system is embedded on it, emitting heat in case of fire or fire danger in sufficient quantity to cause foaming. This can contain material emitting heat so as to cause foaming by chemical reaction, typically by combustion or crystal-formation and using an electrical resistance heater. ...

A lubricant composition which is environmentally acceptable when used with hot forging of aluminum workpieces comprises a metal soap composition containing no lead, plus amounts of polybutene, graphite, thickening agent, mineral oil and, optionally aliphatic solvent.

An improved process for the preparation of polyenes by the Julia reaction comprises carrying out the allylation of the anion of an allyl aryl sulfone generated a strong base, and the elimination of arylsulfinic acid to form a double bond in the same inert polar solvent which is immiscible with water, preferably in a ketone of the formula I R1-CO-R2(I) where R1 and R2 are each straight-chain or bra...

The invention relates to a laparoscopic instrument for looping hollow vessels and for applying endoligatures in the abdominal cavity. The instrument has an instrument tube (4), which can be introduced through a trocar cannula into the abdominal cavity. Within the instrument tube (4) is provided a spiral spring element (8), which is kept there in the unrolled state and can be slid out of the front ...
