  • Publication number: 20220165471
    Abstract: An inductor comprises a base having a top surface, a bottom surface, and at least one side surface. The top surface is spaced from the bottom surface. The at least one side surface connects the top surface to the bottom surface. A core is located on the top surface and coupled to the base. At least one coil extends helically about the core. The at least one coil has at least one end extending outwardly from said core. At least one lead is coupled to the at least one coil and extending outwardly from the base in a coplanar relationship with the bottom surface. A circuit card assembly including the inductor and a method of manufacturing the circuit card assembly are also disclosed herein.

  • Patent number: 7500556
    Abstract: An adjustable conveyor bed that is adjustable in length to span a gap between two devices of a conveyor system includes a primary section and a secondary section that is extendable and retractable relative to the primary section. The primary section has opposite primary sidewalls and a plurality of primary rollers mounted thereto. The primary rollers include a primary motorized roller and a plurality of primary idler rollers interconnected with one another via a plurality of drive members. The secondary section has opposite secondary sidewalls, with the secondary section sidewalls being nestedly received within the primary sidewalls and being adjustably mounted to the primary sidewalls and extendable and retractable relative to the primary sidewalls to adjust a length of the adjustable conveyor bed. The secondary section is configured to support at least one secondary roller when extended a sufficient amount from the primary section.
