Abstract: A spray orifice particularly adapted for discharging a mixture of an atomized release agent entrained within a gas stream for coating a surface of a forming die. The orifice includes a body section having an internal cavity terminating in a ball-shaped cavity portion adjacent its outlet end. The outside surface of the body adjacent the outlet end has a shape complementary with the inside surface to provide a relatively uniform wall thickness. A laterally extending slot is cut into the end and has a maximum width at its center and tapers to a minimum width at its lateral ends. Such configuration reduces the likelihood of finely atomized liquids dispersed in the pressurized gas stream from recombining to form larger size droplets. The included angle of discharge from the slot is adjustable through a rotatable adjustment cap having diametrically opposite cam surfaces which selectively cover side portions of the slot. A lock nut is used to maintain the adjustment cap in a desired set position.

Abstract: A closed loop method and apparatus for unloading particulate materials from a transport container into a supply bin is disclosed. Material is conveyed from the discharge manifold of the transport container via vacuum into a transfer unit. The transfer unit has a vacuum zone and a pressure zone. The material is transferred from the vacuum to the pressure zone within the transfer unit and is conveyed via pressure to a cyclone separator mounted upon the supply bin. The particulate materials are separated in the cyclone separator and dropped into the supply bin. The overhead stream from the cyclone separator on top of the supply bin is returned to the discharge manifold on the transport container. Excess pressure developed in the supply bin is relieved into the transport container. Excess pressure in the transport container is filtered before being vented to the atmosphere.

Abstract: An automatic combinatorial weighing apparatus includes a double collection chute assembly disposed in delivery paths for passage of articles to be weighed. The double collection chute assembly includes an inner collection chute having an outlet and a pair of outer collection chutes having respective outlets, the outlets being connected to timing hoppers, respectively. Articles flow down the inner and outer collection chutes at as equal speeds and in as equal times as possible, the speeds being increased as much as possible, due to valleys created by flat plates which form the chutes. To prevent an increase in noise produced by hitting engagement of the articles with the chutes as the articles flow down the chutes at high speeds, a vibration damper having a vibration-restriction damping capability is disposed in an area of the delivery paths for damping the vibration to suppress the noise.
