  • Patent number: 7845487
    Abstract: A tripper car adapted to transfer particulate material such as coal while maintaining a reduced level of dust proximate the area in which said tripper car moves. The tripper car continuously receives coal from a moving conveyor belt and transfers the coal from a first to a second location. At the second location, the tripper car discharges the coal to a silo that stores the coal for subsequent use by boilers. The tripper car sprays liquid, such as water, to reduce the accumulation of coal dust within a structure in which the tripper car operates as well as to wash the inner walls, ceiling and other proximate surfaces to reduce accumulation of coal dust. The spray pattern is oriented to reduce the spraying of liquid on the coal.

    Abstract: An apparatus for handling and transferring an article formed in an injection molding machine includes a pair of spaced tracks. Inner ends of these tracks are positioned below a mold carried by the machine with the tracks positioned transversely to opening and closing movement of the mold by the machine. On these tracks is a slideable basket which may be moved from the track inner end to an outer end away from the machine. The basket is operatively connected to a pneumatic drive operated by a controller. During forming of the article, the basket moves under the mold. When forming is complete, the mold opens and the article ejected. The article falls into the basket which has a cushioney surface to inhibit damage. Opening of the mold is sensed by the controller to activate the pneumatic drive and move the basket and article to the track outer end where the article is removed. Concurrently the mold closes to begin a further forming cycle.

  • Patent number: 4256217
    Abstract: A storing and conveying apparatus for mortar and similar substances includes a silo-shaped container supported on legs and having a bottom discharge opening, and a screw conveyor mounted underneath the discharge opening of the container, having an inlet opening in a substantial registry with the discharge opening of the container, and being pivotable about substantially horizontal axis between first and second position. In the first position, the discharge and inlet openings are alignedly juxtaposed with one another, and in the second position, the discharge and inlet openings are spaced from each other and inclined at a given angle with respect to one another. An intermediate member of tubular configuration is interposed between and clamped by the conveyor and the container, the intermediate member having respective open ends which respectively communicate with the discharge opening and the inlet opening and extend along planes which enclose the given angle with one another.

  • Patent number: 4218168
    Abstract: A slope or list sensor placed on a floating vessel detects listing thereof in either direction and produces an electrical signal which is proportional to the degree of list. An overhead movable flowable material delivery means responds automatically to the signal from the sensor and moves laterally of the vessel to load the vessel in such a way that the list is corrected automatically during the complete loading of the vessel. Various types of material delivery devices capable of responding to a signal can be employed.

  • Patent number: 4098390
    Abstract: A skip for channelling a load of straw bales to be received by a conveyor is provided. The skip is large enough to receive a load of bales tipped into it from a trailer or other bale transporter. The skip has a conveyor in its floor and in use is set up with one end higher than the other. At the higher end an exit for single bales travelling lengthwise up the floor of the skip on the skip's conveyor is provided through which the bales are conveyed one at a time. The sides of the exit are shaped to turn back incorrectly arranged bales which have travelled up the skip, and these sides may be constituted by frusto-conical rollers. A transverse liftable barrier may also be provided across the width of the skip to knock back bales resting on top of other bales.

  • Patent number: 4061221
    Abstract: An apparatus for loading particulate materials includes a flexible discharge chute having an accordion outer pipe 7 surrounding an inner pipe 3 comprising a plurality of telescopingly nested skirt sections 4 connected by chains 5. A flared hood 8 having a flexible lower skirt 10 is connected to a support ring 13 at the lower end of the chute, and the hood has a plurality of air intake ports 11 and adjacent material detecting contact switches 12. A winding apparatus 14 for raising and lowering the hood, and simultaneously contracting or expanding the chute, is controlled by the switches 12. Dust particles swirling up under the hood and skirt are drawn up through the annular space between the inner and outer pipes to a collector and precipitator 15, which separates out the dust particles and returns them to the discharge chute.
