Abstract: A pair of splines each in the form of a thin metal strip are inserted into respective grooves or slots adjacent the opposed facings of a pair of structural panels. Each panel further includes an insulating foam core disposed between and attached to the opposed pair of facings. An adhesive applied to the metal splines bonds the splines to each panel and securely connects the two panels along respective abutting edges. In one embodiment, each metal strip is provided with opposed turned-in edges which function as hooks for engaging each panel's foam core and preventing separation of the two panels, particularly during curing of the adhesive. In another embodiment, each spline further includes a foam insulating strip about which the spline's metal strip is substantially wrapped for providing a thermal barrier at the panel juncture.

Abstract: Apparatus for use as a lighthouse in the manufacture of a color cathode ray tube (CRT) includes a housing with a cover lens. Disposed within the housing is a light source assembly including a light source in the form of a cylindrical shaped mercury lamp and an optical aperture closely spaced to the mercury lamp. The mercury lamp directs light through the optical aperture as well as through the cover lens onto the inner surface of the CRT's glass faceplate in a photo-stenciling process for registering, or aligning, phosphor dots on the faceplate's inner surface with electron beam passing apertures in the CRT's color selection electrode, or shadow mask. The optical aperture is elongated, with its longitudinal axis aligned generally transverse to the longitudinal axis of the mercury lamp, and is curvilinear having from two (2) to eight (8) inflection points along its length.

Abstract: A partial oxidation reformer comprising a longitudinally extending chamber having a methanol, water and an air inlet and an outlet. An igniter mechanism is near the inlets for igniting a mixture of methanol and air, while a partial oxidation catalyst in the chamber is spaced from the inlets and converts methanol and oxygen to carbon dioxide and hydrogen. Controlling the oxygen to methanol mole ratio provides continuous slightly exothermic partial oxidation reactions of methanol and air producing hydrogen gas. The liquid is preferably injected in droplets having diameters less than 100 micrometers. The reformer is useful in a propulsion system for a vehicle which supplies a hydrogen-containing gas to the negative electrode of a fuel cell.

One of the seal facings of either the rotating or stationary sealing ring includes a plurality of notches positioned on the outer radial edge of the sealing surface at an angle of approximately 45.degree. with respect to the perpendicular peripheral surface of the sealing ring.

Abstract: An engine analyzer having a dual-trace digital oscilloscope includes a memory for storing a library of digitized waveform patterns, the patterns being stored together with identifying data for each pattern and lists of groups of patterns respectively corresponding to different vehicles and/or engines. The analyzer includes a user interface for inputting identifying information relating to the vehicle under test, a waveform acquisition module and a central processor for cooperation with the memory and the oscilloscope for acquiring, digitizing and storing an analog input waveform from the vehicle engine and displaying it on a first trace of the scope in accordance with selected display parameters.

Abstract: A pneumatic scraping tool includes a pneumatic hammer assembly including a cylinder in which a piston reciprocates for repeated impact against an anvil or blade holder which is rotatably received within an end of the cylinder and carries a scraping blade. The anvil has an annular flange which stops its insertion in the cylinder, and is retained in place by a nut threadedly engaged with the cylinder and having an end wall spaced from the cylinder end a distance slightly greater than the flange thickness to permit reciprocation of the anvil. Exhaust air passes along a groove in the outer surface of the cylinder to an annular chamber in the nut and thence through four exhaust ports exiting at the end wall of the nut. A plug portion of the anvil projects through a central opening in the nut end wall and is received into a socket in a blade housing. Blade fingers project laterally into the socket.
