Abstract: A cover (10) is disclosed for holding objects such as papers and reports. The cover (10) is formed of a member (20) having a front cover (22), a spine (24) and a back cover (26). A first portion (32) and a second portion (38) are folded over to encapsulate a prong fastener (12). The second portion (38) is then fastened to the back cover (26) with adhesive tape (58). The first and second portions (32, 38) can be part of a fastener assembly (70) having a third portion (72) that is secured to the inner surface (62) of the back cover (26). In a modification, a flap (128) can be hinged to the side of the back cover (126).

Abstract: A cover (10) is disclosed for holding objects such as papers and reports. The cover (10) is formed of a member (12) having a front cover (14), a spine (16) and a back cover (18), a ring binder (22) and a paper surround (24). The paper surround (24) encapsulates the ring binder (22) and secures it to the member (12). The cover can be either a top bound or side bound cover.

Abstract: A laminated structural panel is formed of top, bottom, and one or more intermediate layers of material having low strength at high temperature and with perforated high temperature, high strength materials interleaved between the top, bottom and intermediate layers. Brazing material is clad on the top and bottom layers and the intermediate layer or layers may be entirely of brazing material or clad on both sizes with brazing material, such that when the assembled stack is subjected to high temperature in a high vacuum environment brazing material is caused to melt and fill the perforations in the high strength material. A particular application is for structural panels, used as shelves in manufacturing electronic chips or displays where aluminum is advantageous because it does not outgas or release particles under the high temperature, high vacuum environment used to make the product. Aluminum, however, does not maintain its strength and stiffness at the high temperatures involved.

Abstract: Laminated structural panels and the method of producing them involve selection of a desired member of sheets of sheet metal of the desired thickness and material, perforating one or more of the sheets to a desired pattern depending upon characteristics desired such as lightness, stiffness or inclusion of fluid passageways etc., stacking the perforated sheets with imperforate face sheets top and bottom and, with brazing material at the interface between the sheets, subjecting the stack to a temperature high enough to cause melting of the brazing material while maintaining a very high vacuum environment. In an alternative embodiment, one or more imperforate internal sheets may be interleaved between the perforated sheets.

Abstract: A circuit board panel and chassis assembly comprises hollow panels for mounting circuit boards and a chassis provided with ducting communicating with inlets and outlets in the faces of the hollow panels for the circulation of coolant. Expansible retainers for sealing the inlets and outlets of the panels to the chassis ducting also free the panels from the chassis upon release of the panels and are operable by levers accessible from the exterior of the chassis.

Abstract: A valve actuating mechanism for an oil cooler bypass valve of the type in which a thermally responsive element expands to urge a valve member against a valve seat and thereby cause oil to flow through an oil cooler. A valve member is utilized which is movable independently of the thermally responsive element, and a relief spring is interposed between the valve member and the thermally responsive element to transmit expansion of the element to the valve member. The valve actuating mechanism is designed to allow oil to pass through the valve despite incorrect connections between the ports of the bypass valve and the ports of the oil cooler and oil source. In one embodiment in which the valve member comes into engagement with a valve seat, the relief spring is adapted to accommodate expansion of the element subsequent such seating whereby damage to the bypass valve components is avoided.
