Abstract: A method and apparatus for evaluating window regulators of the type having a reversible electric motor connected to a-slide/carrier plate by means of cables. The apparatus comprises a first transducer such as a piezoelectric accelerometer or a laser for generating a first signal quantity related to periodic noise produced by the motor during operation thereof, a second transducer such as a piezoelectric accelerometer for producing a second signal quantity representing transient noise produced by irregularities in the slide/carrier plate assembly during travel of the carrier plate along the slide, and a processor for decoding the first and second waveforms and using data derived therefrom as a basis for identifying unacceptably noisy window regulator assemblies. The method comprises placing the window regulators on a test fixture, operating the window regulator with a simulated glass load, and generating and processing the first and second signal quantities as described above.

Abstract: An overhead conveyor system transports a selectable workpiece from vertically extending storage racks having a plurality of horizontally extending shelves with stationary stacks of workpieces to be processed on each shelf. Each shelf includes horizontally spaced shelf support members defining openings complementary to horizontally extending support members of a carriage. The horizontally extending members of the carriage are insertable between adjacent horizontally spaced shelf members to engage the upper most workpiece supported by the shelf located below the horizontally extending support members of the carriage. Workpiece engaging members operably associate or engage the upper-most workpiece with the carriage for movement vertically and horizontally along the path of travel to a workstation for processing.

A female component having a body with a threaded bore that is used for engaging the male component. The threaded bore of the female component matingly engages a portion of the threaded outer wall and the wedge ramp when screwed thereon.

Abstract: A decorative fastener assembly including a nut insert and a decorative cap. The cap includes a flatted portion sleeved over a flatted portion of the nut insert and further includes a flange portion proximate its open lower end. An O-ring seal is compressed between the flange of the cap and the circular enlargement of the nut insert to preclude the entry of moisture between the cap and the nut insert. A top end wall portion of the cap is welded to an annular weld projection on the top end of the nut insert in surrounding relation to the central bore of the nut insert. As the weld projection is melted to perform the welding operation, the cap moves further downwardly on the nut insert to further compress the O-ring seal between the cap flange and the circular enlargement of the nut insert. The cap flange portion proximate its open lower end is then crimped over a circular enlargement of the nut insert.

Abstract: The concept of electromagnetic bandgaps (EBG) is used to develop a high quality filter that can be integrated monolithically with other components due to a reduced height, planar design. Coupling adjacent defect elements in a periodic lattice creates a filter characterized by ease of fabrication, high-Q performance, high port isolation and integrability to planar or 3-D circuit architectures. The filter proof of concept has been demonstrated in a metallo-dielectric lattice. The measured and simulated results of 2-, 3- and 6-pole filters are presented at 10.7 GHz, along with the equivalent circuits.

Abstract: A process is provided for the production of formaldehyde from methyl chloride. In the process methyl chloride is oxidized with air over a catalyst to give formaldehyde and hydrogen chloride. In a preferred embodiment of the invention, a mixture of two different catalysts is used, one catalyst to promote the hydrolysis of methyl chloride to methyl alcohol, and the other catalyst to oxidize the methyl alcohol so formed to formaldehyde. The reaction kinetics can be regulated by adjusting the proportion of the two catalysts in the mixture. In this manner, the release of heat from the reaction can be controlled and excessive temperatures in the catalyst mixture can be avoided.

Abstract: The invention is a ball valve for controlling the flow of fluids between one of two inlets and an outlet. The two inlets are substantially coaxially located, permitting a single inlet point in a fuel supply vessel, yet still allowing two pickup points from within the vessel, such as for a “main” and a “reserve” source. The invention has a particular utility in fuel tanks for providing both a “main” and a “reserve” fuel source, such as for internal combustion engines.
