    Abstract: In an arrangement for mixing fiber components, for example fiber flocks, especially in spinning preparation, fiber web production or the like, in which the fiber material to be supplied is conveyable into at least two weighing containers and, when weighing is complete, the fiber material is dischargeable from the at least two weighing containers onto a mixing belt, the weighing containers are arranged one after the other—seen in the direction of travel of the belt—above the mixing belt. In order that accurate weighing, troublefree production and increased throughput can be achieved in a simple manner, the position of at least one weighing container can be adjusted transverse to the longitudinal extent of the mixing belt.

  • Publication number: 20080283551
    Abstract: A method and apparatus are provided for administering micro-ingredient feed additives to animal feed rations. The apparatus may be referred to as a system which includes a number of discrete components which cooperate together to ultimately deliver micro-ingredients to a desired location, such as a feed mixer containing a feed ration. Structure is provided for storing, measuring, dispensing, and conveying the micro-ingredients. Measuring of the micro-ingredients may be achieved by loss in weight, gain in weight, or volumetric metering methods. Transport by a liquid carrier such as water may be achieved by providing one or a plurality of conveyance pumps connected to a transport line. The system is operated by a control unit which controls components of the system to achieve delivery of specified amounts and types of micro-ingredients to the feed ration.

  • Patent number: 7411136
    Abstract: Multiple-batch train loading systems and methods, for example for loading coal, which are capable of accommodating railcars of a wide range of capacities and designs. Each railcar is loaded with at least a relatively large initial weighed batch having a weight at least approximately equal to the maximum available capacity of a weigh bin, and a relatively small final weighed batch. The initial weighed batch and the final weighed batch are both made up with precision. If required, one or more intermediate weighed batches are loaded into the railcar. The intermediate batches, if required, are made up rapidly, but not necessarily with precision.

  • Patent number: 7410623
    Abstract: A dispenser (200) dispenses an amount of concentrate in a container (204) using a diluent to form a use solution. A dispenser includes a housing (201). A product holder (210) is positioned to support the container (204) with the concentrate in the cavity of the housing. The product holder (210) carried by a scale (240), wherein weight of the concentrate is concerned. A moveable container holder (215) is moveable between a first position and a second position. The container holder is positioned between the housing (201) and the container (204). A cover (216) is operatively connected to the container holder (215) at a connection. A cam surface is adjacent the housing (201). The cover (216) has a cam (216d) for contacting the cam surface (201a), wherein when the cover (216) is moved from a closed position to an open position, the connection moves upward, thereby carrying the container holder (215) and the container (204) which are moved upward lifting the container (204) off of the product holder (210).

  • Publication number: 20080189055
    Abstract: A system and method of calculating chemical usage during a refilling of a supply tank, which includes the steps of providing a chemical system having a first supply tank of known capacity, wherein the tank is mounted upon an electronic scale. The scale is capable of generating a series of signals related to the weight of the tank when empty and at various levels of fill. A system controller receives a series of signals from the scale relating to the weight of the tank when empty and at various levels of fill. The first supply tank is filled from a source of chemical feed and the fill time for the filling of the first supply tank is obtained. The system controller inputs the series of signals from the scale relating to the weight of the tank when empty and at various levels of fill and calculates a usage during refilling based on a feed rate times the fill time.
