Abstract: A low profile surface mountable toroid inductor. The apparatus features a one step molded housing which includes a cover and opposing mounting legs. The housing is molded in a liquid crystal polymer. The length of wire that provides the turns on the toroid also serves as the mounting pads as each end of the wire that is left exposed during the housing molding process is then wrapped around its corresponding leg to provide a mounting pad. The apparatus is able to achieve a thickness that is less or equal to 1.5 mm by eliminating the thickness of a prefabricated cover. Further, a flat surface can be molding into the housing so that the apparatus can be positioned with “pick and place” techniques. Also, the apparatus can be configured so that it can be mounted upside down as well.

Abstract: A symmetrical bobbin especially adapted for the automatic manufacture of electrical coils. The bobbin, formed of high-strength plastic material, comprises first and second lips formed at terminal ends thereof and first and second flanges spaced inwardly from the lips. The bobbin surface between the flanges defines a main coil winding space and the bobbin surfaces between the lips and corresponding flanges define first and second terminal winding spaces. Immersion soldered terminal connections, of high physical strength, durability and electrical conductivity, are formed by extensibly wrapping electrical wire from the main coil about the terminal winding spaces and subsequently immersing the wire-wound terminal winding spaces in molten solder to provide a circumferential bond of unitary structure for terminal connection.

Abstract: The present disclosure relates to mercury containing reed switches and to methods of preparing switch blades for use in such switches. Heretofore such reed switches have been doped with mercury after the reed switch blades have been mounted in the envelope, the mercury migrating to the contact area of the switch blades, made of a mercury-wettable material, after sealing. The present invention avoids the expense and complexity of this procedure by improving the control of mercury dosing to enable improved performance of such reed switches in low power applications, for example in automatic test equipment, process control equipment and data processing terminals.
