Abstract: A tethered aerial vehicle, connected to an anchorage system in the ground level through a cord, comprising a pair of fixed wings; and a drive assembly. The drive assembly comprises at least two actuators configured to tilt the axle of the propellers. The fixed wings define a center hole located close to a gravitational center of the aerial vehicle. Within the edges of the center hole located close to the gravitational center of the aerial vehicle is a gimbal anchored to the fixed wings' structure. The drive assembly is located within the edges of the center hole and attached to the gimbal in a manner that the gimbal interfaces the connection between the fixed wings and the drive assembly. The drive assembly comprises of at least two propellers mounted on the same axle (“coaxial propellers”) driven by a counter-rotating motor. The coaxial propellers are configured to rotate in opposite directions with respect to each other.

Abstract: A single bracket serves to both attach a TXV bulb to an outer surface of an outlet header and to place a securely hold the distribution assembly in a fixed position with respect to the TXV bulb. A pair of clam shell clamping members on opposite ends of a central member are put in position and clamped to hold the TXV bulb tightly in place against the outlet header and to clamp around the equalizer of the distributor assembly, thereby resulting in a rigid interconnection which maintains the desired positions for each of the components.

Abstract: An inlet header (22) of a microchannel heat pump heat exchanger has a tube (34) disposed therein and extending substantially the length of the inlet header (22), with the tube (34) having a plurality of openings (36) therein. During cooling mode operation, refrigerant is caused to flow into an open end of the tube (34) and along its length to thereby flow from the plurality of openings (36) into the inlet header (22) prior to entering the microchannels (24) to thereby provide a uniform flow of two-phase refrigerant thereto. A bi-flow expansion device (41) placed at the inlet end of the tube (34) allows for the expansion of liquid refrigerant into the tube (34) during periods in which the heat exchanger operates as an evaporator and allows the refrigerant to flow directly from the header (22) and around the tube (34) during periods in which the heat exchanger operates as a condenser coil.

Abstract: Condensate formed on a horizontally oriented multi-poise evaporator coil is caught between a top coil slab and a bottom coil slab using a splitter, and is directed to a condensate pan located under the bottom coil slab, using at least one splash guard.
