  • Patent number: 6208501
    Abstract: A standing axial-leaded surface mount capacitor is formed of a dielectric chip capacitor sandwiched between first and second blocks. The end blocks have profiles to match the profile of said chip capacitor. The end blocks are conductive at least on their outer surfaces and serve as leads to attaching to metallic surface traces of a printed circuit. In one preferred embodiment, the end blocks are ceramic cubes with metallic surfaces on its faces. The metallized cubes give the device rotational symmetry about its long axis, so that the capacitor will have identical performance in any orientation. This feature makes it possible to automatically pick and place the device onto a circuit board. Preferably, the dielectric chip has a square profile of the same dimension as the ceramic cubes. The profile of the cubes and the chip can be 20 to 25 mils to match the width of a typical printed circuit trace. The capacitors can be of any typical value, i.e., between 0.05 and 300 pf.

  • Patent number: 3967939
    Abstract: The subject invention relates to a method and apparatus for removing hot exhaust treatment gases containing tin or titanium compounds associated with glass making operations. The apparatus and method herein described comprises exhausting the treatment gases through a plurality of directed fluid treating patterns whereby the hydroscopic materials are hydrated forming aggregates and the suspended particles are wetted, passing the exhausted gases over a supply of a treating fluid whereby some of the aggregates and wetted particles are removed, exposing thereafter the exhausted gases to ions in an electrostatic field so that the remaining aggregates and wetted particles are charged and travel under the influence of the field, and removing the charged aggregates and particles by a descending fluid film.
