Abstract: A deployable and inflatable roof, wall, or other structure has first and second covers made of flexible panels and cables arranged from edge to edge along the covers. Couplings along the edges of the covers connect the structure to supports, such as rails on which the structure can deploy and other supports of a building. Air from blowers blow air in between the covers to inflate the structure like an air cushion. In addition to cables, lateral support for the structure can use struts disposed edge to edge along the covers. Traction or rack and pinion drive mechanisms or cable drive systems can be used to deploy and retract the structure along the rails to cover or open a rooftop or other opening or area of the building.

Abstract: The specification describes a method and an apparatus for detecting and quantitatively assessing wear of a machine having ferromagnetic components subjected to wear during operation resulting in the production of ferromagnetic particulate wear debris, and a lubrication system utilizing a lubricating fluid, in which the wear debris becomes entrained, for lubricating the components. The method comprises the steps of passing a sample stream of the lubricating fluid at a predetermined rate of flow axially through the core of an inductance coil of a sample oscillator for producing a time varying signal which deviates from a predetermined value in proportion to the mass of ferromagnetic material contained in the fluid passing through the core, monitoring the rate of change of signal and activating an indicator when the rate of change of the signal exceeds a predetermined level.

Abstract: The invention disclosed is a jig to facilitate the inscription of a pattern on a substrate, typically a glass microscope slide. The jig includes means for positioning the substrate and template means overlying the substrate. The pattern is preferably u-shaped to define a liquid flow channel along the long dimension of the slide for use of the inscribed slide in ferrography.

Abstract: The invention disclosed is a slide holder which facilitates viewing of the entire slide on a microscope. The holder comprises slide positioning means for positioning a slide for viewing in a horizontal position on a microscope stage and integral mounting plate means for attachment of the holder to the stage, specifically the lateral bar of the stage, such that the slide in viewing position is disposed centrally on said stage and laterally off-set from the center of the stage, and is movable with the lateral bar. The holder is particularly suitable for the positioning and viewing of thin slides typically used in ferrography.

Abstract: A pressure reactor which avoids leakage and prevents sample loss upon depressurization. Leakage is avoided by providing a reaction vessel with a screw-threaded closure member. Loss of sample is prevented by the provision of a vapor trap which collects any liquid or vapor which may include dissolved sample, from escaping upon disassembly i.e. de-pressurization of the reactor. A novel solvent system for use in conjunction with the reactor is also disclosed.
