Abstract: A vibration control system for a rotor hub provides vibration attenuation in an aircraft by reducing the magnitude of rotor induced vibratory. The system can include a force generating device attached to a rotor hub which rotates along with the rotor at the rotational speed of the rotor. Vibratory shear force is generated by rotating unbalanced weights each about an axis non-concentric with the rotor hub axis at high speed to create large centrifugal forces. The rotational speed of the weights can be a multiple of the rotor rotational speed to create shear forces for canceling rotor induced vibrations. The amplitude of the generated shear force is controlled by indexing the positions of the unbalanced weights relative to each other, while the phase of the shear force is adjusted by equally phasing each weight relative to the rotor.

Abstract: A fill probe with an in-line mixer accelerates and facilitates automation of a fill and mix procedure required in formulating certain chemical products. In some formulas, the concentrated chemical components that combine to form the resulting formula (e.g., teat dip) have a wide range of viscosities. The in-line positioning of the mixing attachment with the fill probe on the outside of the fill probe creates a dual action mixing operation that mixes the components as they are deliver to a mixing container and continues to mix them after they are combined with other chemicals within the mixing container. By using a combination fill probe and in-line mixer of the claimed design, a user can automate the fill and mix process, decrease the required mix time, and reduce foaming and spillage of chemicals.

Abstract: A technique is described by which a predetermined amount by weight of ground coffee can be packaged into a container while the coffee density may vary within a range. The amount of ground coffee is supplied into a container along a feed path to fill the container and form a column that extends above the upper rim of the container. The ground coffee is compressed to a predetermined head level by compressing a region around the feed path while leaving a small column of uncompressed coffee. In another embodiment, the volume of the container is expanded during compression by outwardly deforming a container end. This enables the stiffening of the ground coffee to support a smooth unbeaded outer wall after vacuum packing without paneling effects.

Abstract: The apparatus comprises an inclined chute to which the articles are delivered in portions and from which they slide down into a tray which oscillates in a horizontal direction together with the chute. The tray is open at its end remote from the chute and at the top, but closed on its remaining sides. The tray is pivotally supported in extensions of the chute side walls so that it can pivot between a horizontal loading position and a vertical discharge position. In front of the open end of the tray there is provided a vertical plate which is coupled to the chute and the tray in such a way that in the horizontal position of the tray it closes the open tray end while in response to the pivoting of the tray to vertical position it is moved some distance down into the mouth of a subjacent bag, substantially retaining its vertical orientation. During the emptying of the tray the plate functions as one of the walls defining a discharge opening through which the articles are transferred to the bag.

Abstract: A method and apparatus for filling multi-cell or honeycomb cored panels wih fibrous insulation is described. Bales of insulation are reduced to particulate composition and evenly distributed within honeycomb panels.Insulation reduced to particulate composition is temporarily stored in an insulation feeder. Located within the feeder is a reciprocating grating that disperses the stored insulation at a controlled rate.

The panel is conveyed over a vibrator to evenly distribute the insulation contained therein. The panel is also conveyed under reciprocating and rotary brushes that extend into the panel interior for uniformly packing the insulation to achieve an even predetermined insulation density. Flexible scrapers are located between the rotary brushes to scrape the surfaces of the panels clear of any insulation remaining on such surfaces.
