Abstract: A liquid bait station for ants has separate nested inner and outer container sections with the inner container forming a liquid bait reservoir. The inner container section or reservoir has a lid that is closed whenever the outer container is closed, and access to the reservoir of liquid bait by the ants is indirect via one or more container access ports leading to a compartment inside the outer container and then via separate reservoir access ports leading from the compartment to the reservoir. In one embodiment, the reservoir lid comprises a raised portion in the inner surface of the outer container's own cover and the reservoir access ports are formed by depressions in that raised portion. In a second embodiment, the inner and outer container sections have separate lids, but at least one tang depending from the outer cover closes and holds down the inner lid whenever the outer cover is closed. The reservoir access ports can be holes in the inner lid.

Abstract: A method for the dynamic cleaning of semiconductor fabrication equipment and particularly quartzware with thermally activated diluted nitrogen trifluoride at elevated temperatures, typically at the process operation temperature, wherein the cleaning effluent is safely removed and cleaning by-products isolated or diluted to provide for efficient cleaning and rapid restarts of fabrication equipment so cleaned.

Abstract: A process for producing a glass-coated article having a silicon substrate and the article produced thereby are provided. According to the process of the present invention, a layer of glass wetting agent material is formed on the substrate to improve wetting of a glass material to the article. A desired thickness of the glass material is applied to the layer of wetting agent material. The article is then fired and subjected to ambient conditions sufficient to melt the glass material and to form a substantially uniform layer of glass material that is substantially devoid of void pockets and deformities. Particular utility for the present invention is found in the areas of fabrication of electronic circuit boards and semiconductor devices, although other utilities are contemplated.

Abstract: A non-powered portable dishwasher, especially suited for insertion within a sink, has an enclosed dish-holding container with a rack for separating dirty dishes and a sealable top member for creating an enclosed washing chamber. Suspended from the top member, vertically descending, intermediate the various dirty dishes to be washed are a plurality of flexible washing bladders. Each of these washing bladders in turn has a series of washing apertures permitting the spray of water. Each of the washing bladders is manifolded to a wash-water manifold, which provides for connecting a continuous flow of hot water to the dishwasher, as well as providing for the addition of soap or detergent. When the dishwasher is assembled, filled with dirty dishes, and a source of hot water is supplied, the individual washing bladders will fill with the supplied water and detergent swelling to a larger size contacting the dishes.

Abstract: Apparatus for location in places where foodstuffs are or may be stored takes the form of elongated tubes of shapes and sizes so that mice can go through them. Cartridges carrying a rodenticide placed at intervals along the tubes so that mice traversing the tubes contact the rodenticide and become affected by it. A particular feature of the invention is that the rodenticide is provided on raised parts of the cartridges which the mice have to stretch over, so making maximum contact with the rodenticide.
