Abstract: An edge protector for placement between an edge and a rope according to embodiments of the present invention includes an inner surface having a rope guide, the rope guide including a first guide rail, a second guide rail, and a rope travel path between the first and second guide rails along which the rope slides in a rope travel direction, and an outer surface comprising one or more edge engagement bands, the one or more edge engagement bands oriented substantially perpendicularly to the rope travel direction and configured to engage the edge to deter slippage of the edge protector with respect to the edge.

Abstract: An electrically operated refrigerant expansion valve has a refrigerant metering orifice extending therethrough. The valve includes a tapered opening extending thereinto, generally transverse to and intersecting the refrigerant metering orifice. A tapered valve member extends into the tapered opening to cooperate with the tapered opening to control the flow of refrigerant through the valve. The cooperation of the tapered valve member and the tapered opening is such that the flow through the valve body is completely shut off when the tapered valve member is fully inserted into the tapered opening. An electrically actuatable means is mounted on the valve for imparting axial movement to the tapered valve member into and out of the tapered opening.

Abstract: An electrical connector for use with an electric device including first and second winding sections. The connector comprises a plug including a plurality of outwardly extending blades and a socket defining a plurality of receptacles for receiving the blades. The socket has first and second longitudinally spaced apart positions. In the first position, the receptacles receive the blades for connecting the winding sections in parallel and for connecting the winding sections to a first voltage source; and in the second position, the receptacles receive the blades for connecting the winding sections in series and for connecting the winding sections to a second voltage source.
