  • Patent number: 4250866
    Abstract: A forced air furnace includes a conventional fuel fired, primary heat exchanger and a secondary heat exchanger associated with the stack. The secondary exchanger includes a phase change material having a transition temperature within the range of the stack temperature, and which is disposed in heat exchange relation with the flue gases flowing through the stack. The secondary exchanger also includes duct means for conveying the circulated air in heat exchange relation with the phase change material; and the flow path through the secondary exchanger is an alternative path controlled by a damper. When the primary exchanger is turned on, the phase change material in the secondary exchanger is charged from the flue gases of the primary exchanger. When the phase change material is in condition to release stored heat, a temperature responsive control shuts off the primary exchanger and diverts the circulated air through the secondary exchanger.

  • Patent number: 4228701
    Abstract: A carrier takes up a gin saw blade blank from a magazine stack, swings the blank to position over a collet chuck on a continuously rotating vertical spindle, and places the blade on the chuck. The chuck is actuated to clamp the blade thereto and the chuck is shifted laterally to move the blade into cutting engagement with a cutter wheel having peripherally spaced teeth. The chuck drive includes a yieldable mechanism to permit intermittent stopping of the blade as the cutter teeth pass through. After the cutting cycle, the chuck is again moved laterally to the load-unload position; and an ejector removes the blade from the chuck, after release by the chuck, and carries it to a storage spindle for finished blades. During the cutting cycle, the carrier is moved back to its position over the magazine to pick up a succeeding blank for deposit on the chuck. Apparatus functions are performed by air cylinder motors controlled by a bank of air valves operated by cams on a common cam shaft.

  • Patent number: 4225273
    Abstract: A hollow drive spindle is rotatably mounted on a base and carries a self-opening threading die; and the spindle is driven by a suitable electric drive motor. An air operated collet chuck is mounted on a carriage, for reciprocating the chuck in longitudinal alignment with the threading die. The apparatus is semi-automatic in operation including an electric control circuit and actuator mechanisms operated in response to movement of the carriage. When the carriage reaches its rear limit position the chuck is opened to release the rod and the threading die is closed. When a rod is inserted in the chuck at the beginning of a cycle, it engages a stop arm so that further forward force on a rod also moves the carriage toward the die. With initial forward movement of the carriage, the chuck is closed on the rod and the stop arm is moved out of interference position.

  • Patent number: 4224597
    Abstract: The speeds of two wheels are detected by means of wheel speed transducers associated with each wheel, each producing a DC voltage signal proportional to the respective wheel speed. The circuit includes two electric comparators, each having two inputs and one output, each output controlling a fault indicator in the form of an incandescent light. The two inputs for each comparator are the two produced DC voltage signals; and each comparator is identified with one transducer which provides a triggering wheel speed signal, with the other transducer providing a reference wheel speed signal. Sensitivity resistors provide a positive bias on the reference signal input to each comparator. Normally the two wheel speed signals are the same; however, when a triggering wheel speed signal increases a selected amount relative to the reference wheel speed signal, responsive to an underinflated tire, the associated comparator switches to activate the fault light to indicate an underinflated tire.

  • Patent number: 4218278
    Abstract: A stake flag consists of a segment of flagging strip adhesively secured to the end of a wire stake. The apparatus includes a roller chain conveyor, driven at a continuous rate of speed, having fixed carriers for conveying the stakes transversely in parallel spaced relation. A conveyor for a strip of flagging material carries the strip in a path coincident with the path of the wire stakes, with one end of the stakes overlying the strip. A stake hopper, with automatic release, releases stakes sequentially to the conveyor carriers; and a glue gun deposits a quantity of glue on each stake end, and on the adjacent underlying portion of the strip, to provide immediate adhesion of the stake and strip. A rotating cutter blade coacts with a backing roller to sever the flagging strip into flagging segments adhering to respective stakes; and a rotating mechanism rotates the stake in the conveyor, after severance, to fold and press the segment onto itself and onto the stake.

  • Patent number: 4187189
    Abstract: A body for the storage of heat or for the storage of coolness is, in its solid phase, a conglomerate of a mass of crystalline particles of a salt-hydrate, and a rigid cellular support structure in the form of a crust formed by a chemical reaction with the surfaces of the crystalline particles. By way of example, strontium nitrate is reacted with uniformly sized crystalline particles of sodium sulfate decahydrate to form an integral support crust structure of the compound strontium sulfate, which compound is insoluble in water. When the crystalline particles are transformed to the liquid phase, the liquid is confined within the cells of the support structure. The body is enclosed in a moisture impermeable skin to prevent evaporation of the water of crystallization in the liquid phase.
