Abstract: The invention is concerned with a multilayer carrier film for supporting a fluid synthetic resin composition impregnated fibrous mat against a surface, for example the inside surface of a pipe, during the curing of the resin. The film comprises a nylon layer (preferably nylon 6) having on one surface a layer of a polyamide copolymer having a softening point at a temperature below 170°C (for example a nylon 6/12 copolymer in which the nylon 12 component lies in the range from 35 to 55% by weight) and on the other surface a layer of a weldable synthetic plastic composition, for example a polyethylene ionomer. The fibrous mat which may consist of polyester, acrylic or polypropylene fibres is heat-bonded to the polyamide copolymer layer of the multilayer film. The film is resistant to delamination by the resin composition.

IPC: H01J37/32

Abstract: A glow discharge unit suitable for making surfaces such as carbon-coated electron microscopy grids and glass cover slips hydrophilic. The use of a vacuum leak detector (Tesla coil) in place of a conventional high voltage power supply and a small plastic desiccator for the vacuum chamber make the unit very inexpensive. Due to the small volume of the chamber and the simplicity of the unit, the whole glow discharge process can be carried out in only 2 to 3 min., a time considerably shorter than that required for conventional vacuum evaporators. The hydrophilic surfaces thus obtained improve adsorption of particles by several orders of magnitude in preparation for negative staining, freeze-drying and other procedures.

Abstract: A textured, continuous, multi-filament polyester yarn has an ethoxylated alkyl aryl alcohol based sur­factant incorporated into the interfilamentary struc­ture thereof either during the texturizing process or after the yarn has been made into a gauze-like fabric substrate (30). The ethoxylated alkyl aryl alcohol based surfactant is characterized in that it is water disper­sible and water insoluble; has an HLB scale in the range of 7-10; is compatible with conventional wallpaper glues; is of a viscosity in the range of 50-100 SUS depending on the yarn denier; and has a smoke point greater than 350°F. The yarn so treated is formed into a gauze fabric substrate (30) and affixed to the rear surface of a sheet material such as a vinyl wallcovering (40). When the glue (52) is applied to the sheet material the surfactant treatment alters the normally hydrophobic characteristics exhibited by the textured polyester yarn so that the characteristics actually become hydrophilic. Because of the hydrophilic charac­teristics glue is accepted into and held within the interfilamentary structure of the yarn until the sheet material is affixed to the wall (50) or other surface, thereby bonding the substrate thereto.
