Coatings, which act as barrier layers to inhibit migration of alkali metal ions from a glass surface and/or act as colour suppressing underlayers for overlying infra-red reflecting or electrically conducting layers, are deposited by pyrolysis of a gaseous mixture of a silane, an unsaturated hydrocarbon and carbon dioxide on a hot glass surface at a temperature of 600 DEG C to 750 DEG C.

An intruder sensor contains a microwave detector (14, 16, 18) and a passive infra-red detector (8, 10) in the same housing (2). A panel (4) in the housing defines a series of Fresnel lens segments (6) which define the zones for the infra-red sensitive element (8). The panel (4) also forms the radome for the microwave detector. In the twin horn microwave detector, the infra-red sensitive element (8...

Aqueous solutions of organic acids or bases are obtained by a process in which (a) an aqueous solution of a salt of an organic acid or of an organic base and (b) respectively, an aqueous solution of an inorganic base or of an inorganic acid are each passed into compartments of an exchange cell which are separated from one another by an ion exchange membrane, and the solution (a) and (b) are transp...

The utility model relates to a super thin polar plate storage battery, comprising a casing, end covers, a lead electrode, leading out conductor wires, a sealing ring, an air locker, etc. The positive and negative plates are made of pure lead, spread by lead plaster, matched with polyester fiber belts and lap wound to form a population of cylindrical pole. The utility model has the advantages of li...

The utility model relates to a device which can change wind energy into electric energy, being in particular suitable for a small sized electric generator driven by weak wind (the annual average wind speed is 2.5 metres/second). The design of the utility model is originative, and the way of charging an accumulator is unique. Thereby, a wind wheel can work normally after the wind wheel is operated ...

The utility model discloses a mini wind-driven generator with high efficiency, comprising a power generating structure with high overloading performance and a special-purpose adjustor, adopting a swirl to increase energy. The benefit of the utility model is over 1-2 times higher than the existing mini wind-driven generator.

The utility model discloses a universal solar-energy tank making use of the solar energy, composed of a hot and cold cavity, and a motor cavity and a comprehensive cavity which are coated by a heat insulating shell and are isolated by transparent plates, an absorbing and reflecting plate, a gathering and dispersing plate, a low-boiling point actuating medium, etc. When the solar-energy tank is use...

PURPOSE:To securely grip a container at a perpendicular attitude by providing two freely rotatable rollers and one driving roller for gripping the collar of the mouth part of the container at three positions, two roller support rods which are freely opened and closed to right and left, and a mechanism which opens and closes the support rods to right and left. CONSTITUTION:The container 3 is placed...

The present invention is directed to a process for the production of optionally cellular, polyurethane and/or polyurethane-urea moldings having an impervious skin by reacting in a closed mold a reaction mixture containing (a) at least one organic polyisocyanate, (b) at least one compound which has a molecular weight of about 400 to 12,000 and at least two isocyanate-reactive groups, and (c) option...

The disclosed system determines the concentration of components of body fluids using test carriers and an instrument to evaluate the test carriers. The instrument has an electronic evaluating system with a processor which, on the basis of information transmitted to it concerning the batch-specific evaluation curve of the particular test carrier batch used, calculates the concentration (C) from a v...

As new chemical products, the products (I): in all the possible stereoisomeric forms and mixtures of these stereo- isomers and their application to the synthesis of pesticide products.

A shaped article of synthetic resins, such as polydiethylene glycol bisallylcarbonate, is coated with the following coating composition and then irradiated with ultraviolet rays, whereby the coating composition deposited on the shaped article is cured to form a coating film having an excellent abrasion resistance, surface smoothness, adhesion to the substrate resin, flexibility, heat resistance, s...

A method of reinforcing a tissue product such as glass fibre, by applying discrete curable polymer to fill interstices of the tissue to increase tear resistance of the product.

A fabric having a shiny face is made on a two-bar stitch bonding machine. A reflective yarn is laid in over at least two needles so as to appear densely on one fact of the fabric only.
