  • Patent number: 6058526
    Abstract: The drain assembly is constructed with a segmented ball valve of stainless steel or plastic which is rotatable between an open position and a closed position by a shaft extending from the drain body. An annular valve seat is biased against the valve body by a compression device and an annual retainer which is threaded into the valve body from above. A strainer may also be provided to catch large particles which might otherwise not be desirable for passage through the drain assembly. The valve body provides a relatively large opening for the discharge of fluids into a drain pipe.

  • Patent number: 5564334
    Abstract: A pin oven for curing a decorative or other coating laid down by a rotary decorator on cans has an associated transfer device by which the cans are decelerated and transferred in succession from the decorator onto the chain of the oven. The chain carries two cows of pins which are arranged in staggered and offset relation. By operating at a smaller chain circulating speed than the can output velocity of the decorator, the oven provides benefits in the size and thermal efficiency of the oven and reduced chain wear.

  • Patent number: 5272970
    Abstract: A pin oven for stoving a decorative or other coating laid down by a rotary decorator (28") on cans has an associated transfer device (40") by which the cans are decelerated and transferred in succession from the decorator onto the chain (20") of the oven. The chain carries two rows of pins which are arranged in staggered and offset relation. By operating at a smaller chain circulating speed than the can output velocity of the decorator, the oven provides benefits in the size and thermal efficiency of the oven and reduced chain wear.

  • Patent number: 5231926
    Abstract: A continuous motion cylindrical can decorator is provided with mandrels that receive undecorated cans and a deco chain that carries decorated cans through a curing oven. The mandrels are mounted along the periphery of a continuously rotating carrier. Chain speed is much slower than linear mandrel speed and spacing between pins on the chain is much less than spacing between mandrels. Interposed between the chain and the mandrel carrier is a continuously rotating transfer carrier having a plurality of suction holding devices thereto. As the holding devices move through a transfer region they are in single file and receive cans that are blown from the mandrels. In the transfer region mandrel linear speed is substantially greater than linear speed of the holding devices, and spacing between the latter is much less than spacing between mandrels As the loaded suction holding devices move downstream through a pickup region cans thereon are loaded on two rows of pins carried by the deco chain.
