Abstract: A packaging system for clutch sets. The system includes a box provided with several packing sheets of compressible foam which can be custom fitted to the clutch set components. The packaging system allows several sizes of clutch sets to be securely packaged in the same size box, and the compressible foam provides a lightweight means for stabilizing the components during shipping or storage. The outside of the box is unmarked except for a label on one side for a bar code or other information. The system includes a sleeve like wrapper with a hole in the side to reveal the label on the side on the box. The outside of the sleeve is imprinted with a brand name and other trade dress. This allows a bearing manufacturer to maintain an inventory of various sizes of pre-packaged clutch sets, along with an inventory of preprinted sleeves. Then, upon receipt of an order from a retail customer, the time necessary to complete the private label packaging of the clutch sets is substantially reduced.

Abstract: A modular medical gas services unit with multiple medical gas outlets supported at the same level on the column. The unit preferably comprises a hollow column with an internal space for housing the gas conduits and power lines. The medical gas supply outlets are mounted so that their longitudinal axes extend radially from the vertical axis of the frame, and the longitudinal axes of adjacent outlets intersect to form an acute angle. In this way, the horizontal dimensions of the column can be minimized while the number of medical gas outlets at the desired height is maximized. In one embodiment, the column is pentagonal in cross-section providing five planar support surfaces for five medical gas outlets. In another embodiment, a square column is equipped with angled outlet panels, each supporting two medical gas outlets. Thus, though the frame is four-sided, as many as eight medical gas outlets can be mounted at the same height on the frame.

Abstract: A detonator assembly wherein the electrical leads are attached to an electrical connector which maintains the ends of the leads in non-conductive, waterproof condition and which permits the leads to be spliced to another pair of electric leads without any splicing tools. The length of the electrical leads is selected to permit the assembly to be inserted in a booster charge so that the electrical connector is contained entirely within the throughbore in the booster charge. Packaging for such detonator assemblies includes at least one tray integrally formed of fire retardant material. The detonator assemblies fit snugly in parallel elongate recesses in the top of the tray so that when the tray is tipped or inverted the detonators will remain in position. The detonator assemblies are arranged in alternating fashion so that the detonator ends of adjacent assemblies are at opposite sides of the tray.

Abstract: An improved ground source heat pump system wherein the subterranean piping installation comprises modular heat exchange units. Each modular heat exchange unit comprises a plurality of parallel secondary conduits. The secondary conduits are connected between primary conduits by means of multi-tiered inlet and outlet manifolds. Each manifold comprises a three-way "T" or end member and at least one and probably several four-way connecting members. Each of the end members has one inlet and at least one and preferably two outlets. Each connecting member has one inlet and at least two and preferably three outlets. The inlets and outlets of the end members and connecting members are configured to interconnect interchangeably in male-female fashion. Elbow units are used to connect the ends of the secondary conduits with the inlets and outlet of the end members and connecting members. Thus, only two types of components are necessary to build heat exchange units having any number of secondary conduits.

Abstract: A method and apparatus for forming a window in well casing. First, using coiled tubing, a two stage whipstock is set in the well casing through the production tubing. Next, a jointed milling assembly is inserted through the production tubing, also using the coiled tubing. The travel of the mill is guided by the two stage guide surface of the whipstock, and the joint in the milling tool allows the direction of the mill to change. Thus, the mill impinges on the well casing at a relatively acute angle to the longitudinal axis of the casing reducing the likelihood that the mill will bite into the guide surface of the whipstock instead of the well casing.

Abstract: An improved ground source heat pump system wherein the subterranean piping installation comprises modular heat exchange units. Each modular heat exchange unit comprises a plurality of parallel secondary or branch conduits. The use of multiple parallel secondary conduits significantly increases the heat exchange capacity of the system. Because of the increased efficiency of such a system, less piping is required, which in turn reduces the cost of labor and materials to install such a system and the area of land mass required to contain it. Moreover, because the heat exchange units are modular, they can be prefabricated at a remote site and then conveniently transported to construction site and installed much more quickly than the extended lengths of conventional piping.

Abstract: A length of leg wire comprising a pair of electrical leads is coiled into a conical helix. An electrical connector is attached at one or both ends. The electrical connector is characterized as capable of maintaining the ends of the two electrical leads in non-conductive and preferably also water-resistant condition. The connector further may also be characterized as permitting a water-resistant, high tensile strength splicing of the ends of the leg wire with another pair of similar electrical leads without the use of splicing tools. The other end of the leg wire may be clean cut or connected to another electrical connector. The coiled portion is flexible but shape sustaining and therefore collapses and expands in the coiled arrangement. The assembly is packaged in the collapsed configuration. When removed from the package, the coiled portion of the leg wire expands but retains the coiled configuration.

Abstract: A concealed services module comprising a frame, service outlets mounted on the frame and a picture assembly. The frame preferably is installed inside a wall so that only the service outlets are exposed, and the picture assembly is mounted over the outlets to conceal them. The picture assembly also may be mounted over existing service outlets in a wall. The picture assembly is slidably mounted for up and down movement, and includes a device such as a counterbalancing mechanism to retain it in the up position.
