Abstract: A flexible solid-state resistor comprises a string of ceramic resistors that can be used to charge the capacitors of a linear transformer driver (LTD) used in a pulsed power machine. The solid-state resistor is able to absorb the energy of a switch prefire, thereby limiting LTD cavity damage, yet has a sufficiently low RC charge time to allow the capacitor to be recharged without disrupting the operation of the pulsed power machine.

Abstract: An air disinfection module for use in a HVAC system comprises a first and second housing, each of the housings including at least one support member adjustably coupled with the other to form a framework for varying the lateral distance between the first and second housings. The housings further comprise a lamp assembly that includes at least one ultraviolet radiation source communicating with and projecting from its respective housing towards its opposite housing, and a radiation pervious protective sleeve disposed about the radiation source. Electric transmission means are also included which communicates with the ultraviolet radiation source(s) and with at least one source of electrical power to provide electricity to the ultraviolet radiation sources. At least one cross support member communicating with the protective sleeves and the support members is provided for supporting the sleeves and their corresponding ultraviolet radiation sources between the first and second housings.

Abstract: An improved sorting apparatus for separating loose debris, rocks and clods of dirt from root crops such as potatoes includes a channelizing conveyor, a take-away conveyor having an inlet end positioned below the discharge end of the channelizing conveyor, and a plurality of diverter paddles aligned with the channels of the channelizing conveyor. The channelizing conveyor includes an endless series of segments, each segment comprising a bar having hook portions at the ends thereof and an elastomeric molding formed thereon. Each molding includes several uniformly spaced, wedge-shaped projections, and the projections are longitudinally aligned to form channels for the potatoes, rocks and clods. The segments are interconnected with the hook portions thereof being engaged upon the trailing segment.
