Abstract: A tray for temporarily or permanently receiving beads for bead work has a plurality of separate compartments, each with a separate cover. A single sheet of material can be vacuum formed to create the compartments, and the covers can also be vacuum formed. A rib on the covers is received within the compartments and frictionally engages the side walls to hold the covers in place. One end of each compartment has angled walls to provide a funnel arrangement, leading to a pour spout, and an upwardly ramped bottom portion directs beads to the spout. The cover can be reversed and used to prevent spilling of beads during pouring. The tray can also define one of more design grooves for laying out the pattern of beads.

Abstract: A plural component dispensing system includes flow monitoring system to interrupt operation and/or provide an audible and/or visual warning signal to an operator if the flow of one component of a plural component material stops or reaches an unacceptable value. In the flow monitoring system, a pilot valve can be connected with a pressure generated to indicate the flow of the monitored component, and with an adjustable pressure indicative of acceptable/unacceptable flows, and can provide an output to interrupt system operation in the event of an unacceptable flow of the monitored component. In systems of the invention where operation is not interrupted, a warning signal can alert the operator to discontinue dispensing the plural component material until the cause of the unacceptable flow condition has been investigated and corrected.

Abstract: In an external mix, plural component application system, a first component material, such as a resin, is formed into a plurality of small, spaced streams arranged in a two-dimensional array and projected generally at a substrate or article. A second component material, such as a catalyst, is formed into two air-entrained sprays of second component material and directed at the plurality of small, spaced streams of the first component material from adjacent the opposite sides of the array of streams to assist atomization of the small, spaced streams into particles of first component material and to mix the plural components. A plurality of flows of compressed air are directed at the substrate or article from adjacent the opposing sides of the array of streams that are between the two sprays of second component material and provides containment of plural component emissions.

Abstract: A marine fuel tank includes a "sump" tank compartment. The sump tank compartment projects from and below a main fuel tank compartment. A bottom cover plate, covering the sump, has a large hole in its center in communication with one end of a connection tube. The bottom cover plate for the sump also includes two small holes directly in front of and behind the connection tube, aligned with each other in a direction of travel. These holes allow fuel to move from the main fuel tank compartment of the fuel tank into the sump tank compartment. As the main fuel tank compartment is filled with fuel, the fuel flows to the sump tank compartment by gravity feed through the holes in the cover plate of the sump tank compartment. A fuel pickup tube extends through the connection tube and into the sump tank compartment and its free end is free to move inside the sump tank compartment as moved by the dynamic acceleration forces acting on the fuel pickup tube.

Abstract: A gravity-actuated switch having a switch module with a switch housing and a lid. An electrically conductive pendulum is pivotally secured to the lid via a pivot pin so that the pendulum hangs within the housing and pivots with respect to the housing under the influence of gravity. A first electrical contact connectable to a power source abuts the pivot pin, which is electrically conductive. A second electrical contact is provided within the housing in a predetermined position such that the pendulum makes contact with it when the switch module is tilted by a predetermined amount. When the pendulum makes contact with the second electrical contact, a short circuit is provided across the pair of contacts, thus closing the switch. The switch is incorporated in a lamp assembly provided on the underside of the hood or trunk lid of an automobile to selectively provide power to a lamp so that the lamp is illuminated only when the hood or trunk lid is opened by at least a predetermined amount.

Abstract: An easel hinge includes an outer hinge plate and an inner hinge plate interconnected with each other for relative pivotal movement therebetween. The outer hinge plate has a relatively flat leaf portion terminating in a curled barrel at one side thereof and at least two spaced apart notches formed in the curled barrel. The inner hinge plate has a relatively flat leaf portion and at least two spaced apart lobes extending from the inner hinge plate leaf portion in a plane generally perpendicular to the plane of the inner hinge leaf portion. The lobes are received in the curled barrel of the outer hinge plate through the notches of the curled barrel for permitting relative rotational movement of the inner hinge plate with respect to the outer hinge plate. Lugs formed on the lobes limit the relative rotational movement of the hinge plates and prevent the longitudinal movement of the plates with respect to each other.

Abstract: A one-piece hexagonal junction adapter for use in a conventional plural line clamping system that generally comprises two opposed U-shaped channels having semi-cylindrical collar portions for supporting the junction adapters and stacking nuts which are disposed between the channels and help secure and separate adjacent adapters. The axial thickness of the hexagonal body portion of the junction adapter of the present invention is substantially equal to the width of or distance between the opposed interior side walls of the U-shaped channels. The junction adapter has two retaining shoulder portions, each located between the body and one of the two cylindrical collar support portions that engage the semi-cylindrical collar portions of the channels. These features enable the junction adapter to fit more securely within the plural line clamping system and provide greater resistance to movement due to forces resulting from extremely high fluid line pressures.
