Abstract: A gooseneck hitch adapter has an upper assembly that is designed to affix to an existing trailer. The upper assembly has an upper and a lower torsion tube that each has corresponding torsion bars. The torsion bars extend outwardly where each affixes to a corresponding torsion arm. The hitch adapter has a lower assembly that is designed to affix to a towing vehicle. The lower assembly has an upper and a lower torsion tube that each has corresponding torsion bars. The upper torsion arm affixes the upper torsion bar of the upper assembly to the upper torsion bar of the lower assembly. Correspondingly, a lower torsion arm affixes the lower torsion bars of the upper assembly to the lower assembly. The torsion tubes and bars resist rotation and cooperate to allow limited movement and provide resistance to forces along the axes of the upper and lower assemblies.

The arrangement further includes at least a first motion-transmitting means designed to impart an oscillatory movement to the first outlet lip relative to, and in the lengthwise direction of, the second outlet lip.

Abstract: An apparatus that promotes the flow of materials has a body having an inner shape for holding the materials, a wall having a shape that approximates a portion of the inner shape of the body, and a vibrator attached to the wall. The wall may be disposed vertically within the body close to the body's inner shape. The vibrator transfers vibrations to the wall to agitate the material and encourage material flow.

Abstract: There is disclosed an apparatus and method which is capable of dispensing very small (typically less than 5 mg) quantities of particles to a high accuracy in a repeatable way and without undue wastage. Also, the need for advanced particle formulation is reduced. The apparatus comprises a closed loop control system which uses an electro-mechanical actuator to deliver impact energy to a supply of particles initially held on a sieve in a hopper. The impact energy causes a small number of particles to fall through the sieve and onto a weight measuring balance. The weight obtained is scrutinised by a processor to see if further actuations are required. In preferred embodiments, the energy of actuation is varied in accordance with the rate of dispensation calculated by the processor. Also, a correction amount can be obtained to take account of the fact that the balance can take a considerable amount of time to settle to its final value.

Abstract: A bulk-solid metering system has a support structure. A feed hopper is mounted with respect to the structure and has an upper edge. In the improvement, the structure includes an upper member and the upper edge is below such upper member. The structure defines a lateral opening sized and shaped to permit the feed hopper to be withdrawn laterally through the opening. The feed hopper includes a spout extending therefrom. In a highly preferred embodiment, the lateral opening is positioned to permit withdrawal of the feed hopper in a direction away from the spout. The feed hopper is configured to promote very good mass flow as well as to permit agitation in that, in one embodiment, it has a body made of flexible material. There is a hopper upper flange and the spout is spaced below such flange. The body has a first cross-sectional shape, e.g., circular, adjacent to the upper flange and has a second cross-sectional shape, e.g., ellipse-like, intermediate the upper flange and the spout.

Abstract: A vacuum excavation system is provided in which a vacuum is generated for withdrawing dirt, water or other material from a vacuum excavation site, and whereby such material is delivered to a containment structure, preferably of the hopper type having a discharge. A valve is provided for the vacuum, such that actuation of the valve interrupts the vacuum, whereby material pickup may be discontinued and/or material may be discharged from the containment structure. Preferably the vacuum-controlling valve exists in a conduit between the situs of vacuum generation and a containment structure. The valve will preferably be controlled by a pneumatic/electrical control for operation of the same.The excavation system is preferably vehicle-mounted, with the same motor that drives the vehicle also driving an air compressor for operating a pneumatic tool as well as driving the vacuum generator.

Abstract: In a material transfer system, material from an excavation is drawn into a vessel by suction from a vacuum source. The vessel has discharge flaps at the bottom that are held closed by the suction. When the weight of the material in the vessel reaches a predetermined value, the flaps open and the material is discharged from the vessel. After the discharge, counterweights almost close the flaps and the suction seals the discharge flaps so that additional material is drawn into the vessel. The vessel includes a vibratory section and has sides that slope outwardly from top to bottom. The material entering the vessel contacts the vibratory section at a predetermined angle and is redirected to the discharge flaps without any caking on the vessel walls. The opening through the discharge flaps is larger than the inlet through which the material enters the vessel so that objects entering the vessel are discharged.

Abstract: An improved hopper includes a pair of opposed live walls and a pair of opposed fixed walls, wherein at least one live wall is moveable relative to at least one other wall. The hopper is suitable for controlling the flow of particulate material of the type which has a tendency to bridge during transportation. A device for imparting vibration is coupled to at least one of the live walls. The live walls are separated from the fixed walls by seams such that the live walls are free to move relative to the fixed walls. By the action of the vibration device, the live walls are moveable relative to each other and to the fixed walls to inhibit the formation of particle bridges and, thus, provide a significant improvement in the capability of controlling the flow of particulate material.

Abstract: An apparatus for discharging dosed quantities of a bulk material from a bin having a discharge end, includes a material loosening unit adapted to extend below the discharge end, a foil unit covering the material loosening unit and extending so as to form a conical surface for contacting directly the bulk material filled in the bin, so that the loosening unit contacts the bulk material indirectly through the foil unit, and a shutter unit associated with the foil unit opposite to the discharge end and movable between an open position and a closed position.

Abstract: The invention provides an agitator for releasing powder toner through a bottom opening of a hopper. The agitator has a screen for placing over the opening and an element which, when positioned in the hopper, is in contact with the upper surface of the screen. Toner normally bridges the openings in the screen so that there is normally no flow through the screen and the element is operable to brush over the upper surface of the screen to break down the bridging locally, thereby effectively sifting powder toner through the screen. On stopping the element, the toner again bridges the openings and flow of toner stops. The invention also provides a feeder which magnetically transports toner received from the hopper, and an applicator which takes the toner magnetically from the feeder and transports the toner to the point of use.

Abstract: A fluid drop dispenser is fabricated from an injection moldable plastic and includes inner and outer components each having an end wall and an axially extending cylindrical wall that define a respective counterbore for each component. The inner component is assembled to the outer component with the respective outer and inner axially extending walls defining an annular fluid receiving chamber therebetween. A nozzle is provided in the outer wall through which drops are ejected on demand. A piezoelectric actuator disc is mounted within the inner component with its periphery bonded to the cylindrical wall of the inner component. When the actuator disc is electrically excited, it undergoes a radially outward expansion to cause a predetermined quantity of fluid to be ejected from the annular chamber through the nozzle.
