  • Patent number: 4756346
    Abstract: Method and apparatus are provided for making multiple continuous or discontinuous gradients. Individual vacuum systems draw the gradient material from a common mixing chamber and deliver it into identical receptacles where each gradient is formed. A battery of syringes can be used to create vacuums on each individual chamber, and an opposing battery of syringes can be used to deliver gradient material to the mixing chamber. By varying the ratio of syringes generating vacuums to syringes delivering gradient material and/or initial solution volumes, gradients of various shapes can be produced.

  • Patent number: 4753275
    Abstract: High speed container placement method and apparatus are provided, particularly for check weighing or for use in combination with high speed filling equipment for consumer products, such as instant coffee. A container separating device introduces groups of containers to a container placement and removal device for sequencing therethrough. The individual containers are transferred from an annular turntable to separate stationary work positions on a deck plate where they undergo a processing step. Following this processing step, the containers are removed from their respective stationary positions and returned to the annular turntable to be ultimately discharged from the container placement apparatus. The containers are placed at and removed from the work positions respectively by feeder and discharge guides which oscillate as they travel about the deck plate along an epicycloidal type path.

  • Patent number: 4750531
    Abstract: An automatic exchange device for format dependent cellular panels used in container-filling machines for filling containers with foodstuffs, flavorings or other liquid to pastiform products, the machines being arranged to pick-up and transport the containers whereby cellular panels are arranged adjacent to each other on a through-conveyor or periodically circulating conveyor and are corrected to the conveyor. A replacement mechanism for the cellular panels. The exchange of panels is effected with the assistance of a manipulator, which automatically detaches the connection with the assistance of a motor driven screw tool and also reattaches the connection after the exchange. After releasing the connection, the manipulator picks up the cellular panel by means of suction cups and removes it via the use of an elevator into a magazine, which, for example, is comprised of a drum with radially arranged partitions.

  • Patent number: 4742852
    Abstract: A self-cleaning feeder for particulate material, such as dry lime powder, utilizes a spaced coil helical spring rotating in an upright annular passage between a pair of pipes to convey the material from a stock pile source, such as a drum container supporting the feeder in upright position, to an outlet in controlled amounts. The coil spring projects into the stock pile and has a laterally extended tail or finger stirring or agitating the material to maintain it in contact with the spring. The inner pipe is bottomed on a plate resting on the bottom of the supply container and the outer pipe is carried above the plate by a spider stand on the plate. An inclined chute or tray supported from the outer pipe receives the material to slide it into a tank or apparatus.

  • Patent number: 4741369
    Abstract: In a fill tube of a vehicle fuel tank, an inlet forming device for receiving the nozzle of an associated fuel pump for filling the fuel tank and including an apertured seal member adapted to encircle the fuel nozzle to prevent fuel vapors from escaping therebetween. The device includes at least one vent opening which is normally blocked by an overlying edge portion of the seal member, but which is movable from its overlying position outward to vent fuel tank pressure. The overlying portion of the seal is normally biased to a closed position by the natural resiliency of an adjacent open celled foamed plastic material which also acts as a filter when the overlying edge portion of the seal is moved to a more open vent position.
