  • Patent number: 4113552
    Abstract: The transfer of agitational forces from a main vessel to an elutriation leg connected thereto is effectively minimized with a slurry inlet and liquor outlet device mounted in the upper end of the elutriation leg. The device includes a slurry flow directing member which receives the gravitational flow of slurry from the main vessel and directs such flow in a downward path of reduced cross-sectional area with respect to the cross-sectional area of the elutriation leg for impingement onto a target member mounted below the slurry flow directing member. The downward slurry flow is radially outwardly deflected by the target member to substantially reduce the concentrated downward forces of the slurry which would otherwise tend to disrupt or restrict the formation and maintenance of a fluidized bed in the elutriation leg.

  • Patent number: 4097252
    Abstract: A horizontal-flow electrostatic filter for gas passing from a boiler to a chimney and having separate flow chambers lying horizontally side-by-side has inlet and outlet ducting arranged such that flue gases are divided to flow in opposite directions through the respective chambers, both directions of flow being at right angles to the direction of the shortest distance between the boiler house and the chimney. The flue gas output of the boiler is divided equally between the chambers. The size and hence capacity of the filter may be greater, in this disposition, for a given said distance than if a prior art parallel co-current flow arrangement (shown in FIG. 1 of the drawings) were used. Capacity for a given available floor space is further assisted by providing a plurality of arrays of collection and discharge electrodes separately electrically supplied and controlled.

  • Patent number: 4097611
    Abstract: A folding paperboard carton having an improved window construction in an elongated rectangular side panel. A preferred embodiment is a rhomboidal carton for sliced and shingled bacon. The side window construction comprises an elongated rectangular piece of non-wrinkling clear plastic which is adhered to the inner surface of the window aperture-containing side panel. The non-wrinkling plastic piece has one edge aligned with a score line between the side panel and top panel. The score line is discontinuous because of the presence of the window openings in the side panel having partitions therebetween hinged to the top panel at the score line. The combined stiffness provided by the apertured side panel and adhered plastic piece serves to cause the discontinuous score line to fold when the tubular carton is erected for filling from its manufactured flat condition.

  • Patent number: 4094779
    Abstract: A novel filtration system for purifying a relatively small volume of water, and especially for removing objectionable tastes and odors from drinking water. An inverted container of the water to be purified is supported above a filter which in turn is supported above a bottom container for receiving the effluent from the filter. The upper container is provided with an outlet tube which extends into the filter and is provided with means for regulating the flow of water to the filter. The filter holds a disposable filter medium in the form of a thin "sandwich" of two outer sheets of readily permeable material and a thin inner layer of activated carbon particles disposed uniformly between the two outer sheets. In operation, water flows from the upper container through the filter into the bottom container, the rate of flow of water from the upper container being controlled automatically by the level of water in the filter.

  • Patent number: 4094042
    Abstract: Apparatus for removing and recovering meat from trimmed and untrimmed bone fragments comprises a hollow sleeve open at one end for receiving a quantity of bone fragments to be processed. Hydraulic cylinders raise the sleeve to bring one end into engagement with an extrusion block, and a piston slidably disposed at the other end of the sleeve is advanced initially by relatively high speed jack cylinders and finally by a low speed ram cylinder to compress the bone fragements against the block. The extrusion block includes a plurality of concentric annular recesses and interfitting extrusion rings which form an inwardly facing foraminous surface through which meat recovered in fluid form as a result of the compression process passes. The rings are slidably received within the recesses to facilitate removal for cleaning, and are partially extended from the recesses by a pneumatic cylinder after each compression cycle to dislodge bone residue from the foraminous surface.

  • Patent number: 4094233
    Abstract: Cold water is supplied through an inlet water line from a source under pressure to a cold water basin from which it is siphoned to a hot water tank therebelow. The hot water is siphoned out of the tank for brewing coffee extract. A valve in the inlet water line is closed when the level of the cold water in the basin engages a probe or collar the elevation of which can be adjusted. Under conditions of low water pressure the siphon to the tank may start before the shutoff level in the basin is reached. Water may continue to flow without that level being reached. The level of the hot water then rises above the siphon out level of the hot water siphon and engages a probe resulting in closure of the valve to prevent further flow through the hot water siphon and overflow of the tank. Should the level of the water in the basin rise above the shutoff level, a float switch is opened to close the valve.

  • Patent number: 4086741
    Abstract: Undercap filler machine and method for cyclically vacuumizing product-containing, conventional spray can type aerosol containers, charging metered quantities of compressed gas propellant thereinto, and crimping valve cap assemblies thereon. By means of sequencing spring action on the crimper head, the machine and method provide (1) accurate control of the cap lift against relatively low sequencing spring force during charging with compressed propellant gas and (2) firm cap seating under relatively high sequencing spring force on the bead of the container opening against the internal pressure therein during crimping. The controlled cap lift during charging introduces a temporary throttling restriction in the form of a predetermined narrow annular orifice between the fill chamber of the crimper head and the interior of each container which orifice produces a controlled drop in the impact gassing pressure and increased velocity of gas flow into the container.
