  • Patent number: 11460870
    Abstract: A device is provided for controlling the flow of a fluid through a conduit from an upstream side to a downstream side of the device. The device includes a valve aperture, a cylindrical mounting member on the downstream side of the valve aperture, a valve member on the outside of the cylindrical mounting member that moves reciprocally to open and close the valve aperture, a control volume defined between the cylindrical mounting member and the valve member, an arrangement for introducing a control pressure into the control volume, and a seal between the outer surface of the cylindrical mounting member and the inner surface of the valve member that substantially seals the control volume. The valve member is acted on by the pressure of the upstream side (P1) and the control pressure (P4) so as to be moved by the difference between these pressures.

  • Patent number: 11453977
    Abstract: A set for mechanical processing suspended fibrous material includes a die plate having receiving openings in a predefined arrangement for insertion of blade-shaped processing elements which jut out on a process side and are flowed onto by the fibrous material. The blade-shaped processing elements have each a plurality of foot regions in longitudinally spaced-apart relation, which pass through the die plate and jut out from the die plate on a process-distal. At least some of the foot regions of the processing elements reach into associated receiving grooves of a base plate on the process-distal side. As an alternative, transverse stiffening elements are arranged substantially orthogonally in the longitudinal direction of the processing elements such that the transverse stiffening elements stabilize the foot regions of the processing elements on the process-distal side.

  • Patent number: 11446731
    Abstract: A support apparatus for supporting a steering rack forged in a forging die, comprising a gripper to grip the shank of the rack, a lost-motion mechanism supporting the gripper and permitting limited movement in the direction of closing of the forging die, and a side-shift mechanism to move the gripper sideways. The lost-motion mechanism abuts the die assembly as the forging die closes thereby positioning the gripper to grip the shank of the steering rack during the final closing travel of the forging die. The gripper then lifts the steering rack as the forging die opens. The side-shift mechanism then moves the gripped steering rack sideways.

  • Patent number: 11440018
    Abstract: A viscous food dispensing system includes a chute inlet configured to funnel particulate food product into a sleeve and a transport device having an over-center cutout. The transport device is configured to rotate within the sleeve to convey the particulate food product. A processing surface extends downward from the chute inlet towards a curved base of the sleeve along a portion of the transport device. The processing surface is spaced laterally apart from the transport device to define a processing zone between the processing surface and the transport device. The particulate food product is processed as the particulate food product is captured between a leading edge of the over-center cutout and the processing surface while the transport device is rotating.

  • Patent number: 11440073
    Abstract: The present invention is directed to a dual sided incremental sheet forming apparatus and method for incrementally forming sheet materials such as sheet metal by utilizing opposed primary and secondary forming tool assemblies and a sheet feeding assembly. The primary forming tool assembly includes a rigid tool and the secondary forming tool assembly includes a compressible and resilient backing layer having either a cylindrical or flat configuration. The sheet feeding assembly positions the sheet material between the two forming tools. The rigid tool applies force to one surface of the sheet material while the resilient backing tool applies counter force to the opposite surface of the work piece as it supports the work piece. This dual sided process localizes the forces on the sheet material so that stresses are advantageously controlled to produce accurately formed asymmetric shapes, without the need for expensive dies.

  • Patent number: 11429121
    Abstract: A method for calibrating a product valve disposed along a flow path in a duct, with a calibration valve in a duct remote from the product valve and having a geometric shape and operational parameters corresponding to those of the product valve. A calibration controller establishes calibration conditions and, in responsive thereto, generates a calibration flow rate (CFM) function by measuring for the calibration valve, a sparse set of flow rates and determining a surface-fit mathematical representation of fluid flow through the calibration valve over applied calibrated flow rates and the measured pressure drops. The CFM Function is transferred to a product blade controller, which in turn, processes the representation of the mathematical surface, and controls fluid flow through product valve based on values extracted from the received CFM Function as well as at least one parameter control signal indicative of a desired set point.
