Abstract: An improved rupture disk assembly and methods and apparatuses for forming a rupture disk are disclosed. The rupture disk assembly includes a rupture disk having a flange connected to a dome-shaped rupturable portion by a transition area. The rupturable portion includes a structural apex formation at or near the apex of the dome and is configured to rupture when exposed to a fluid having a predetermined pressure. Preferably, a safety member is disposed adjacent the rupture disk. The safety member includes a hinge about which the disk bends when the disk ruptures. The present invention is also directed to an apparatus and method for consistently, accurately, and repeatably forming a structural apex formation in a rupture disk before the formation of to the rupture disk dome, during the formation of the rupture disk dome, and after the formation of the rupture disk dome.

Abstract: A handheld inspection mirror uses right angled mirror surfaces and triangular prism means to provide a non-inverted undistorted image from objects located in remote or relatively inaccessible places.

Abstract: A solderable metallized plastic contact includes an element made of a polymer where an electrically conductive material covers a surface of the element so as to form an electrically conductive region on the element. The electrically conductive material is electroplated to the surface of the element. The electrically conductive material in the electrically conductive region is solderable. The electrically conductive material in the electrically conductive region does not delaminate from the surface of the element. Additionally, a method of manufacturing a solderable metallized plastic contact is also disclosed.

Abstract: An improved rupture disk assembly for a pressure relief system is disclosed. The rupture disk assembly is sealed between an inlet support member and an outlet support member, each of which define a central fluid pathway. A rupture disk that includes a flange connected to a dome-shaped rupturable portion by a transition area is sealed between the support members. The rupturable portion may include an indentation positioned at the apex of the dome and a score line having a first and a second end. A safety member that has a hinge including a knuckle and a tongue is positioned between the rupture disk and the outlet support member. The knuckle extends downwardly into the dome and extends laterally across the dome to a point that is inside the area circumscribed by the score line or inside the area circumscribed by an arc connecting the two ends of the score line.

Abstract: A ribbon style electrical connector is provided having at least one variable resistance contact such that an electrical resistance between the variable resistance contact and a corresponding mating contact of a second mating connector varies from a relatively high resistance to a relatively low resistance as the first and second connectors transition from an unmated to a mated position. The ribbon style connector includes a housing having a first end and a second end, with a shroud depending from the first end, the shroud defining a contact chamber. A substrate is mounted within the contact chamber and communicates with the second end of the housing. A plurality of signal contacts are adhered to a surface of the substrate, with at least one of the signal contacts including a resistive portion and a conductive portion.

Abstract: An ultra-low-profile terminator apparatus for a parallel communications bus is provided. The terminator apparatus includes a male style electrical connector which includes a plurality of individual contact pins. An elongated printed circuit board having a first surface and a second surface is mounted perpendicular to the male connector. Conductive vias formed in the printed circuit board communicate between the first and second surfaces of the printed circuit board, and the contact pins of the male connector are press fit into the vias at the second surface of the printed circuit. Electronic termination components are mounted on the first surface of the printed circuit board, and the conductive vias form conductive paths between the termination components and individual contact pins in the male pin connector.

Abstract: Apparatus and methods for practicing golf involve the use of a projected laser light beam that acts as a fixed guide to the hole or target.

Abstract: High pressure boiler condensate returns are polished and softened with a macroreticular cation exchange resin, and the resin is regenerated with a readily ionizable organic acid salt of a relatively low volatility amine corrosion inhibitor.

Abstract: A method and apparatus is disclosed for removing a hub cap and wheel from a vehicle which has four separate elongated members and the members are so designed as to allow the members to be fitted together to form a cross section and provide at least 31 different socket sizes of engineering choice, yet may be packaged and stored side by side to form a compact carrying package.

Abstract: The invention provides immunostimulatory compositions comprising an aggregate immunostimulatory amount ofa) a compound associated with the synthesis of polyamines,b) a nucleobase source,c) omega-3 polyunsaturated fatty acids, andd) omega-6 polyunsaturated fatty acidsthe use of such compositions and their manufacture.

Abstract: A double feed detector to detect the feeding of multiple sheets into processing equipment such as printing presses which includes a reciprocally mounted gauge tube with a passage opening onto its opposite ends so that one of its ends is lowered into a gauging position over a support surface on which the sheets being fed are located. A pressurized air supply is connected to the gauge tube intermediate its ends and a cap closes that end of the passage opposite the end at the support surface so that, when more than one sheet is located on the support surface, the rise in air pressure in the gauge tube will urge the cap against a switch to stop the sheet feed to the processing equipment.
