摘要： A system for mounting a tool in a tool holder combining a means for high-precision centering of the tool and a means for positive restraint of the tool from rotation within the tool holder. The tool holder includes a cylindrical aperture having a diameter slightly less than the diameter of the shank of a cylindrical tool. The tool is installed into the tool holder by heating the tool holder to a temperature sufficient to increase the pocket diameter sufficiently to accept the tool shank. In a first shrink-fit embodiment, the tool shank is further provided with an angular flat for engagement with a set screw to prevent the tool from being turned in the holder in use. In a second shrink-fit embodiment, a groove extending partially around the tool receives a tangential pin through a passage in the tool holder. The tool is rotated in the holder until the pin binds in the groove, thus preventing any further rotation of the tool in the holder during use.

摘要： A rotary machine tool holder has therein intermediate its ends a plurality of balancing screws that are mounted in internally threaded blind bores that extend part way into the holder from equi-angularly spaced points about an outer peripheral surface formed on the holder intermediate its ends, and coaxially of an axial bore in the holder. The screws are adjustable along axes disposed substantially tangentially of the axial bore of the holder, and are prevented from projecting radially beyond the outer peripheral surface of the holder by a plurality of cap screws removably mounted in the holder to have the heads thereof restrict the extent to which the balancing screws can be adjusted toward the outer surface of the holder.

摘要： An apparatus is disclosed for fabricating a laminate product having a pair of sheet materials spaced by a plurality of flexible parallel vanes which are secured to the sheet material so that planar movement of the sheet materials in opposite directions cause the vanes to shift between open and closed positions. The vane material is formed from a web of material by dyeing the material, drying the dyed material, applying spaced longitudinally extending lines of adhesive on opposite faces of the material, and cutting the material into a plurality of side-by-side strips with each strip having a bead of adhesive on each face and along opposite side edges. The cut material with adhesive applied thereto is taken up on a transfer roll and moved to a vane/strip handling station where the strips of material are processed and delivered to a laminating station in parallel overlapping relationship with each other. The laminating station feeds the sheets of material above and below the strips to form the laminate before passing it through the laminating station where the adhesive is first heat activated to bond the component parts of the covering product together, and subsequently cooled to cure the adhesive. The resultant product is wrapped around a take-up roller for delivery to a remote location where the product can be cut to size and operably connected to a control system to form the final covering product for an architectural opening.

摘要： Test structures and methods for superconducting bump bond electrical characterization are used to verify the superconductivity of bump bonds that electrically connect two superconducting integrated circuit chips fabricated using a flip-chip process, and can also ascertain the self-inductance of bump bond(s) between chips. The structures and methods leverage a behavioral property of superconducting DC SQUIDs to modulate a critical current upon injection of magnetic flux in the SQUID loop, which behavior is not present when the SQUID is not superconducting, by including bump bond(s) within the loop, which loop is split among chips. The sensitivity of the bump bond superconductivity verification is therefore effectively perfect, independent of any multi-milliohm noise floor that may exist in measurement equipment.

摘要： An apparatus includes a top conductive layer of on an integrated circuit waveguide filter and a bottom conductive layer. The top and bottom conductive layers are coupled via a plurality of couplers that form an outline of the waveguide filter. A dielectric substrate layer is disposed between the top conductive layer and the bottom conductive layer of the integrated circuit waveguide filter. The dielectric substrate layer has a relative permittivity, εr that affects the tuning of the integrated circuit waveguide filter. At least one tunable via includes a tunable material disposed within the dielectric substrate layer and is coupled to a set of electrodes. The set of electrodes enable a voltage to be applied to the tunable material within the tunable via to change the relative permittivity of the dielectric substrate layer and to enable tuning the frequency characteristics of the integrated circuit waveguide filter.

摘要： A flexible connector includes a unitary connector block having first and second board-facing areas. The first and second board-facing areas are longitudinally spaced from each other on a chosen surface of the connector block. The connector block includes a block body transversely separating the chosen surface from an opposing surface oppositely facing from the chosen surface. The connector block includes a flexible connector bridge longitudinally interposed between the first and second board-facing areas. A first connector port is located within the first board-facing area. A second connector port is located within the second board-facing area. A connector trace extends through at least a portion of the block body between the first and second board-facing areas. The connector trace electrically connects the first and second connector ports. Methods of making and using the flexible connector are also included.
