Abstract: The present disclosure relates generally to an anti-backlash component. In one embodiment, the anti-backlash component includes a housing, the housing comprising a first threaded opening and a second opening, a bolt coupled to the housing through the first threaded opening and the second opening, the bolt comprising a spherical end, a nut coupled to the bolt and an exterior side of the second opening of the housing and a socket coupled to the spherical end of the bolt.

Abstract: A dielectrically-loaded helical antenna has a ceramic cylindrical core and, formed on the cylindrical surface of the core, a plurality of conductive helical antenna elements. The antenna elements are coupled to a pair of feed connection conductors generally centrally located on an end surface of the core, the coupling between the antenna elements and the feed connection conductors being by way of a matching section comprising a laminate board having at least three conductive layers and insulative layers between the conductive layers arranged in an alternating manner. Each conductive layer has a first portion forming part of a respective shunt capacitance, the conductive layers and the insulative layers together acting to form a plurality of capacitors shunt-connected across the antenna elements. One of the conductive layers includes a second portion forming a series inductance between one of the feed connection conductors and at least one of the antenna elements.

Abstract: Co-extrusion apparatus for manufacturing a laminated plastic film or sheet comprises a plug-type layer sequencer including a plurality of channels for conducting a plurality of polymer flows; a transitional aspect ratio block for inducing the plurality of polymer flows to converge; and a flow velocity profiler cartridge for combining the plurality of polymer flows to form the film. In accordance with one embodiment, the layer sequencer includes a tapered selector pin which minimizes mechanical damage when the selector pin is removed. In accordance with another embodiment, the flow velocity profiler cartridge includes inserts fitting within cavities for controlling the polymer flows which form the layers of the film or sheet manufactured by the apparatus. At least one such insert defines lanes within an associated cavity so as to promote the formation of lanes of differing polymer composition within at least one layer of the laminated sheet or film.

Abstract: An exemplary device and method for microfluidic transport is disclosed as providing inter alia a valve membrane sheet (400), an inlet channel (140) and an outlet channel (150). The valve membrane sheet effectively confines transport of fluid from the inlet channel to the outlet channel where fluid may be purged. The valve membrane sheet also generally provides means for preventing or otherwise substantially decreasing the incidence of purged fluid re-entering the inlet channel. Accordingly, the reduction of backflow generally tends to enhance overall pumping performance and efficiency. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve micropump operation in any microfluidic application.

Abstract: The present invention provides a method for the quiet, contactless handling of objects using pickup devices of the Bernoulli type. The method is particularly suitable for the contactless handling of items much larger than an individual pickup, for example the handling of lithographic printing plates. According to the method of the present invention, a flow of fluid is established between the pickup face of the Bernoulli pickup and the surface of the object to be supported. The fluid is made to flow over a laminar flow surface at a velocity sufficient to produce a pressure differential between the flowing fluid and a surrounding fluid medium. Bernoulli lift is maximized by making the laminar flow surface as smooth and protrusionúfree as possible, and by ensuring that the location and extent of the laminar flow surface substantially coincides with the maximal lateral limits of the low-pressure zone between the pickup face and the opposing object surface.
