Abstract: A coating composition comprising a carboxy-functional siloxane fluid, an organic titanate and a volatile diluent is applied to a water-impermeable surface and dried. The treated surface has the properties of promoting water-droplet formation, rather than water-film formation when rained upon and releasing frozen water, such as ice, snow, sleet and frost under a very low force.

Abstract: Uniform and repeatable formation of a resistance element on a substrate is achieved by spinning the coated objects which are still in a wet state while rotating them about an orthogonal axis to subject the wet indicator formulation to centrifugal forces which forces the indicator formulation into contact with the substrate.

Abstract: Conductors are formed in slots in a plate by filling the slots with a carrier medium having high viscosity in which metallic particles are dispersed and then, by lowering the viscosity of the medium, permitting the particles to settle to the bottom of the slots. The carrier medium is then removed, and the metal particles are bonded to the bottom of the slots. A rake-like device is also used to shape all of the electrodes so that they are uniformly spaced from the top surface of the plate.

Abstract: A surface of a substrate 11 (FIG. 2) is uniformly coated with a liquid L by wetting the surface with the liquid and compressibly contacting the wetted surface with an applicator member 10 having an outer layer 14 of a compressible liquid absorbing material with inverse sponge characteristics and an inner layer 13 of compliant material. Preferably the member is a roller 10 having a silicone rubber or polyurethane inner layer and a chamois outer layer. A plurality of the rollers 10 are arranged to be in compressive contact with the surfaces of a plurality of substrates 11 as the substrates are being removed from the liquid L (arrow A), the movement of the substrates 11 causing rotation (arrow F) of the rollers to apply a uniform coating of the liquid on the contacted surfaces.

Abstract: A spray of ink, paint, or other marking liquid is formed and sprayed through a stencil member for marking a part with a stencil character. Various means are provided to periodically move the stencil member for removal of marking fluid to keep the system clean. In one system, the stencil member is rotatable and marking fluid is removed periodically by centrifugal force by rotating the member at a sufficient speed. Removal of the marking fluid may be facilitated by the application of solvent or fresh marking fluid. In another embodiment, the stencil member is moved to a marking liquid removal location where the marking liquid is removed by suction, solvent action, and the like. The removed marking liquid may be collected by providing an absorbent member positioned to receive the removed liquid, or by providing collecting gutters or the like.

Abstract: The invention relates to a negative electron resist for application in electron lithography. It consists of an organic copolymer formed by copolymerization of butadiene or isoprene with glycidyl acrylate or glycidyl methacrylate. The resist exhibits the high sensitivity to irradiation by electrons and, at the same time, a good adhesion to the base and a resistance towards common etching agents. The copolymer is advantageously prepared by radical polymerization and a high purity of the product does not require further purification. The electron resist manufactured in this way has the long-term workability.
