Zinciferous surfaces, particularly those of galvanized steel, may be effectively protected against corrosion, either as treated or after painting, while remaining easy to weld, by contact with an aqueous solution containing chromium in both +6 and +3 valence states, phosphate, a tertiary alcohol or similar oxidation stable, water soluble organic compound as a wetting agent, and a silane coupling a...

A cationically electrodepositable resin composition containing as main component primary hydroxyl group-containing cationic resin obtained by reacting epoxy resin (A) having at least three epoxy group-containing functional groups represented by the following structural formula (I) with primary or secondary amine compound (B) containing primary hydroxyl group and optionally, further phenol c...

2051692 9012024 PCTABS00002 A method of producing synthetic oligonucleotides on a small or large scale using H-phosphonate nucleoside monomers is described. The method can be used to synthesize oligonucleotides of any length, including oligodeoxyribonucleotides and oligoribonucleotides. The method results in a coupling efficiency of greater than 97 % and consumes only two to three equivalents of m...

43031 CAN 9A This invention relates to articles capable of being heated by microwave energy. The use of microwave radiation to generate heat in materials is becoming increasingly more prevalent in both consumer applications and in industrial applications because of the increased speed and lower power consumption of microwave processes, when contrasted with conventional heating processes. Microwave...

The invention relates to a heat insulation product of mineral fibre wool and to a method of producing this. The curable binding agent of the product is an aqueous suspension containing water glass and slag. The slag reacts hydraulically with the alkalis of the water glass, yielding water resistant bonds. During the preparation of the product, the suspension of water glass and slag is agitated befo...

In absorbent products, such as sanitary napkins, discreet areas of dry fibrous materials such as fluid-repellent materials are precisely placed in various planes within the product so as to provide barriers to bodily fluid leakage from the product. In a preferred embodiment, hydrophobic fibers are placed around the periphery of a central absorbent area of an absorbent product to discourage and/or ...

The method which aims at preventing condensation phenomena on tools (5) heated by the work and traversed by a cooling medium relates particularly to synthetic material working machines. In order to avoid condensation of humidity on cooled tools (5), a dry air veil is created by direct blowing to the tools (5), thereby making possible a further reduction of the temperature of the cooling water of t...

A feeder trough for transferring molten glass from a glass furnace to an object-forming station, the feeder trough comprising a channel at one of its ends to the furnace and at its other end to a bowl having at least one feeder orifice a sill which has, on its downstream face, a substantially vertical wall, occupies the entire width of the channel and has a thickness of approximately 4 to 10 cm an...

Before spinning, the laundry articles must already be distributed as evenly as possible in the rotating drum. In known appliances, this takes place during a single smooth start with a subsequent constant reduction speed. The process according to the invention distributes and loosens the laundry articles in a plurality of smooth starts at different reduction speeds. An optimum laundry distribution ...
