  • Patent number: 4299274
    Abstract: A thermal energy storage device and method for making the same. The thermal energy storage device is in the form of a sealed tube-like container such as a tube-like cylinder or other geometrical configuration partially filled with a phase change material such as calcium chloride hexahydrate. The cylinder is made of tubular high density polyethylene and more particularly an ultra high molecular weight high density polyethylene having a molecular weight of about 500,000 to 700,000 which is tough, chemically resistant, withstands low and high temperatures, acts as a moisture vapor barrier and can be fused and sealed. The calcium hexahydrate is filled in an open top cylinder, closed at the bottom by dissolving two parts of calcium chloride dihydrate with one part of water to provide calcium chloride hexahydrate in liquid form. The cylinder is filled to about 90% by volume and a cap of the same material is then preheated to about fusion temperature.

  • Patent number: 4295260
    Abstract: A tool for removing sleeves from cylinders having an unrestricted opening at one end and a restricted opening at the other end. A stabilizer or guide rod device having a disc with a diameter closely approaching the internal diameter of the sleeve is placed adjacent a shoulder of the sleeve with a further disc used as a stabilizer within the sleeve. From the restricted opening of the cylinder housing having an internal diameter less than the diameter of the sleeve a plurality of radial or pie-shaped collar segments are inserted and placed on top of the stabilizer support disc and fitting over the shoulder of the sleeve. A pusher rod is inserted through the restricted opening of the cylinder and connected to the stabilizer support disc with apparatus for clamping the collar segments thereto. The pusher rod with the clamped collar segments extending over the shoulder of the sleeve in clamped relation is moved or pushed to force the sleeve out of frictional engagement with the cylinder and is removed therefrom.

  • Patent number: 4221016
    Abstract: A valve stem cleaner and positioner for threaded valve stems. The cleaner and positioner is designed for use with threaded valve stems in which the portion of the valve stem to be cleaned is inaccessible from the ends of the stem as for example, in an open yoke of a valve and also for use in valve stems where an end is accessible as above the valve hand wheel. For the inaccessible portion of the valve stem the cleaner and positioner is made in hinged half portions with semi-circular members which are adapted to be fitted around the valve stem and hinged together. The cleaner and positioner has inwardly extending wire bristles which engage the threads of the valve stem and a nut portion so that when the cleaner and positioner is opened and fitted around the valve stem by means of closure means the cleaner and positioner can be closed about the valve stem. A wrench fitted on the nut can move the device about the threaded valve stem to any position as desired.

  • Patent number: 4221039
    Abstract: A gasket holder clip and method for using the clip to attach a gasket through holes in an underlying flange or the like to maintain alignment of the gasket holes and flange holes. The gasket holder clip is constructed of spring steel wire or other material of high degree of elasticity and rigidity and has a substantially V-shaped configuration with legs of the V-shaped structure having short outwardly turned arms. The clip is employed to hold a gasket having a plurality of holes against an underlying flange, as in an oil pan flange, having holes for registry with the gasket holes by inserting the clip with the legs pressed together through the bottom of the flange hole up and through the gasket hole and then releasing the pressure against the legs of the clip and drawing it down to engage the arms against the top surface of the gasket. The clip maintains the gasket against the flange by the bearing and biasing action of the legs of the clip against the interior walls of the flange hole.
