Abstract: A machine produces foam-in-bag from foam precursors mixed within the bag. The machine comprises a base and a shell. The base and shell are moveable relative each other between a base/shell disengaged position and a base/shell engaged position. In the base/shell engaged position, the base and shell divide the bag so that a mixing chamber is isolated from the remainder portion of the bag. First and second nozzles inject foam precursors into the mixing chamber. A mixer engages the mixing chamber to provide mixing energy to facilitate the foam reaction.

Abstract: A rotor hub assembly and method for controlling movement of a rotor blade relative to a swashplate. The hub assembly having an attachment device operably associated with the rotor blade and the swashplate. The attachment device provides pivot and rotational blade movement relative to the swashplate. A dual spring-rate damper is operably associated with the attachment device. The damper switches between a first spring rate and a second spring rate during flight to control movement of the rotor blade. The method includes the process of switching the damper between the first spring rate and the second spring rate during flight.

Abstract: A tiltrotor aircraft includes a rotatable nacelle that supports a rotor assembly and is pivotally attached to the air-craft's fuselage. A wing extension attaches to an outboard section of the nacelle. The wing extension provides additional yaw control during helicopter mode and additional lift during airplane mode. A method for controlling at least a portion of yaw movement includes positioning the rotor assembly in helicopter mode, creating rotor wash with the rotor assembly, and pivotally rotating the wing extension in the rotor wash.

Abstract: A modular high shear mixer has a shaft guard substantially enclosing the rotating mix shaft thereof and a mixing member guard substantially surrounding the mixing member formed upon the lower end of the mix shaft so as to enhance safety without undesirable affecting the performance of the mixer.. Modular construction facilitates both mechanical and fluid shearing utilizing a plurality of interchangeable mixing members. The mix shaft is driven by a AC motor, the speed of which is determined by a controller so as to eliminate the need for multiple pulleys.

Abstract: A media mill having a cylindrical vessel which is vertically oriented and a motor-driven rotor extending through the vessel to agitate grinding media and a liquid product within the vessel. A tubular outlet housing extends radially outward from the vessel and forms an opening through which a screen assembly is removably mounted. The screen assembly comprises a stack of adjacently positioned annular rings which are supported on a tubular carrier element. Adjacent screen elements retain the grinding media within the vessel while openings between the elements permit the milled product to flow therethrough and into an interior cavity terminating in an outlet. The screen assembly extends into the interior of the vessel and is removably secured to the outlet housing by a quick disconnect retainer means.

Abstract: A sandmill outlet screen is formed by a stack of rings which have projections and corresponding recesses stamped into them. The projections provide a gap between rings whereby flow passages between the rings are created. These passages permit the liquid being processed by the sandmill to flow out of the sandmill, but keep a grinding media in the mill. With the projections of one ring nested in the recesses of an adjacent ring, a small gap is provided. With the rings oriented to prevent nesting, a larger gap is provided. With the rings arranged so that the projections of adjacent rings abut each other, a still larger gap is obtained. This variable flow passage capability is further enhanced by varying the height of the projections.

Abstract: A horizontal media mill comprising a cantilevered shaft extending from a motor into a vessel in which a rotor mounted on the shaft agitates a grinding media and the product being milled. A cup-shaped screen and a cup-shaped end cover fit over the free end of the rotor and are removably mounted on the end of the vessel. The screen filters the media from the milled product as the product flows to an outlet in the end cover. The rotor is of a one-piece polymeric construction and slides off the shaft to be removable when the screen is removed. The mill is tiltable to facilitate cleaning, and includes an integrated hydraulic system which tilts the mill, cools the vessel, drives the product pump, and provides pressure for a seal where the shaft enters the vessel.

Abstract: The present invention provides a control unit for use with a variable speed system for dispersing, milling or otherwise processing solid particles in liquid. The apparatus used in the system includes a fixed center-drive pulley combination. The control unit automatically resets the pulley combination to a slow start-up position to prevent damage to the system drive train during initiation of a processing operation. In addition, the control unit allows a system operator to precisely and safely adjust the setting of the pulley combination to control the speed of the processing operation. In one arrangement the speed is controlled by manually operated valves that control fluid pressure on opposite sides of a piston that controls the pulley combination. In another arrangement, valves automatically control fluid pressure on the piston to maintain a position in response to a signal from a pressure regulator which is manually or otherwise adjusted to provide a selected speed.

Abstract: Cube-shaped, ventilated, individual light modules housing a lamp or bulb having different predetermined characteristics are interchangeably mounted on an expandable clip surrounding an electrical socket, by sliding the module down on the clip and simultaneously establishing electrical contact between the bulb in the module and a power source and switch. The front of the module is faced with safety glass to protect the bulb and subject, and a space is provided between the module and protective safety glass which can be fitted with one or more, swing-away, wide angle adapter, diffuser, or dichroic lenses.

Abstract: A battery pack connection consists of a flat male plate having a plurality of spaced headed projections and female electrical terminals carried within a projecting housing while a flat female plate has a plurality of keyholes designed to facilitate receiving the projections and male electrical terminals positioned within a recess together with a flexible strip that engages a projection to enable locking and unlocking of the plates in both their electrical and mechanical connected relationship. The flexible strip is moved away from its locking position by a cam on a pivoted actuator which can be moved by a finger.
