Abstract: A test apparatus for use in determining the concentration of oils or other soluble contaminants in a petroleum hydrocarbon solvent. The apparatus includes a positioner for a two-layer fibrous sheet, or two separate sheets, in either case providing an upper layer of material that is sorptive to polar materials and a lower layer that is absorptive to non-polar hydrocarbon liquids. When the contaminated liquid evaporates either, as by being heated, a characteristic stain indicative of contaminant level remains on the lower layer. The method includes applying contaminated solvent, separating particulates in the upper fibrous level, and allowing the soluble materials to stain the lower layer. Some embodiments of the apparatus include built-in heating and air circulation means.

Abstract: A method of controlling the flow of articles between upstream and downstream work stations which respectively produce and modify such articles so that both work stations can operate at the same rates or at different rates.A continuous flow of articles is received on various inbound tracks, and the continuous flow of articles is subdivided into individual arrays or groups of articles. In those instances wherein the down stream use rate is approximately or exactly equal to the upstream output rate, the groups of articles are transferred from inbound lanes or tracks directly to outbound lanes or tracks. In the cases wherein the supply rate or the demand rate, i.e., the upstream or downstream machine rates are different, then groups of articles are periodically taken from inbound lanes and placed in transient storage or are taken from transient storage and placed in outbound lanes.

Abstract: A drain flow control assembly for liquids draining from a sink or the like to a reservoir having a given liquid level. The flow control assembly includes a downtube with its inlet opening above the level of the liquid and its outlet below the liquid level, a divider plate surrounding the outlet opening and extending radially outwardly of the opening a distance equal to at least twice the diameter of the downtube opening. The assembly also includes a radially smaller, imperforate deflector plate positioned beneath and spaced closely apart from the divider plate, so as to form a radially extending transfer space between the two plates. When the assembly is positioned in a liquid-containing reservoir with the downtube outlet below the upper surface of the liquid, liquid flows vertically through the downtube outlet opening and then horizontally through the radial transfer space.

Abstract: A liquid filter apparatus particularly useful in removing particulates from parts washing solvent. A filter assembly includes an exterior, fluid, impermeable container, preferably in the form of a flexible sidewall bag, and an interior filter element with permeable sidewalls and inlet and outlet ends, preferably in the form of a sleeve.

Abstract: A method and apparatus for rapidly determining the cure state of an annular rubber or elastomeric article is provided. The article is placed so that an inner hole portion fits over separable parts of a test fixture, and tension is induced in a stepwise manner by moving the separable parts apart in discrete incremental steps. The tension is allowed to relax between the steps. By generating a force/deflection curve in this way, the user may optimize the cure state of the tested articles by controlling the cure time and temperature of a manufacturing process in response to the measured data.

Abstract: A method of installing a plurality of carrier elements within a building structure. The method includes the steps of determining the intended locations of various carriers within the structure, formulating a record of such locations, assigning to each carrier a location code indicative of the record of the location points comprising its intended path within the structure, storing and retaining the record of the location information in an accessible memory means, such as in a written record or in the memory of a computer, and reproducing at least portions of the codes on portions of each of the carrier elements. The carrier elements are then installed in the structure such that each carrier element follows its intended path, and each carrier element bears a unique code referable to a record that discloses its location path within the structure.
