  • Patent number: 5666845
    Abstract: A rolling mill of the present invention includes a mill stand formed by two spaced apart housings. The housings are configured to rotatably hold one of at least two sets of rolls. A hold-down assembly is coupled to the housings. The hold-down assembly includes at least a first pair of hold-down screws and a second pair of hold-down screws. The distance between the screws of the first pair of hold-down screws is less than the distance between the screws of the second pair of hold-down screws. Each pair of hold-down screws is selectively adapted to substantially align with the bearing chocks of an adjacent roll of one of the sets of rolls in the mill stand.

  • Patent number: 5661884
    Abstract: The present invention provides a descaling system for hot strip or plate mills. The descaling system includes upper and lower spray headers which are offset from each other along the pass line. Each spray header is adapted to direct a high-pressure water spray on the metal product to descale the upper or lower surface thereof. The upper and lower spray headers are offset at a distance greater than the length of the product, whereby the spray headers can be sequentially, separately used. The spray headers are coupled to a common drive pump.

  • Patent number: 5607651
    Abstract: A multiple product dispensing system includes a plurality of use solution dispensers and a controller for selecting one of the dispensers according to a preset regimen, e.g., selecting different dispensers on different days of the week. Each dispenser dispenses a controlled concentration of use solution using a diluent delivery apparatus that delivers a diluent to form a liquid concentrate from a solid chemical composition, and to form make-up diluent for diluting the liquid concentrate and forming a use solution of controlled concentration. A foam reducer reduces the kinetic energy of the make-up diluent prior to mixing with the liquid concentrate to reduce foaming. An unskilled operator may operate the dispensing system to dispense a use solution of carefully controlled concentration, and the controller will automatically select the proper dispenser according to the preset regimen, without any additional input on the part of the operator.

  • Patent number: 5417233
    Abstract: A low product level detector is disclosed which utilizes a sensor comprised of an infrared emitter and receiver to project a beam of light across a cavity/enclosure which contains a solid product. When the product reaches a level at which more solid product should be added, an alarm indicia means is triggered. The alarm indicia means is comprised of an audible horn and a visually perceptible light. The low product alarm is utilized in a dispenser for dispensing a wash chemical solution which has been created by dissolving a solid wash chemical in a diluent. By maintaining a predetermined amount of solid wash chemical in the dispenser, the wash chemical solution maintains a more constant concentration.

  • Patent number: 5411716
    Abstract: Disclosed is a dispenser (10) for use with an automatic floor scrubbing machine (75), and a method for cleaning a floor. The dispenser (10) has a solid chemical (13) which is dissolved by water spray from a spray nozzle (21). The detergent solution is then directed by a conduit (25) to a scrub brush (85). A water reservoir (83) provides water for the detergent solution, and a valve (38) directs water to a rinse conduit (37) for rinsing of the floor. After cleaning, the dirty water or detergent solution is carried through conduit (36) to a recovery tank (84).
