Abstract: A flexible roll-out thermal system, including: a layer of insulating material forming a first outer surface; a layer of conductive material forming a second outer surface; at least one electric heating cable disposed between the first and second outer surfaces; and, an electrical connection element for connecting the at least one electric heating cable to a power source. A method of forming a flexible roll-out thermal system, including: disposing at least one electric heating cable between a layer of insulating material forming a first outer surface and a layer of conductive material forming a second outer surface; and connecting an electrical connection element to one end of the at least one electric heating cable, the electrical connection element for connecting the at least one electric heating cable to a power source.

Abstract: A nozzle assembly for an irrigation system, including: a first portion arranged for connection to a device external to the nozzle assembly, the first portion including a first bore open to a distal end of the first portion; and a second portion including: a first chamber in communication with the first bore; and at least one second bore at an acute angle with respect to a longitudinal axis for the nozzle assembly. The longitudinal axis passes through the first and second portions. The at least one second bore includes: a first port in communication with the first chamber; and a second port at an external surface of the second portion.

Abstract: Double-ended, hollow core socket wrenches, tooled for either an English or metric size nut and bolt engaging means in one socket cavity and tooled for either the closest English or closest metric equivalent size nut and bolt engaging means in the opposite socket cavity, are designed to engage and turn hexagonal nuts on protruding bolt studs. The first type of double-ended socket has an axially central external hexagonal surface drive engaging portion, raised from its' substantially cylindrical shell portion, so that it can can be driven externally with a single-ended socket wrench drive member, while the second type of double-ended socket, designed with the same outer drive mechanism described for the first type, has in addition, an internal axially central square drive well engaging portion, accessible from either open socket end, by a conventional extension drive rod member.
