  • Patent number: 10645885
    Abstract: A debris loader for comminuting or collecting leaves and debris comprises a vacuum tube connected to an intake assembly which connects to a blower housing. The blower housing contains a rotating impeller which creates suction through the vacuum tube and intake assembly drawing in leaves and debris. The leaves and debris are then discharged from the blower housing through a discharge opening or conduit. The intake assembly includes a cylindrical collar, to which a vacuum tube is attached, and a conical section which is connected to the blower housing. The diameter of the conical section expands from its connection with the cylindrical collar toward the blower housing. In a preferred embodiment the conical section is angled downward relative to the axis of rotation of the impeller and preferably at an angle of approximately thirty degrees.

  • Patent number: 6840468
    Abstract: A hand-portable spreader blows particles, such as salt or sand, over an outdoor surface to increase friction. The spreader has a grip and accepts an extension cord to power the blower motor. The motor drives a vane impeller mounted in a housing and connected to a nozzle, similar to a leaf blower, but the intake to the impeller is arranged to suck up particles from a storage chamber. The air passes through the particles in the storage area and then through an orifice, where the air stream velocity increases and particles are picked up and levitated up into a conduit that passes to impeller. After passing through the impeller, the particles and air are ejected from a nozzle to scatter the particles over a surface such as a street or sidewalk to melt ice and snow, for use as a friction (anti-slip) agent.

  • Patent number: 5386857
    Abstract: A method of and apparatus for introducing pulverulent material into a tire through a tire valve stem is performed by confining a predetermined amount of pulverulent material in a cylindrical chamber having axially spaced and radially offset inlets and outlets, subjecting the confined pulverulent material to pressurized air which is transformed into a cyclonic air current within the chamber by the radially offset inlet and outlet, and introducing admixed air/pulverulent material from the chamber into a tire through its associated tire valve stem.

  • Patent number: 5378089
    Abstract: One or more hot melt tanks are each periodically supplied by an air conduit which automatically transfers pellets from a storage container. A transducer assembly, positionable in the container, includes a vacuum transducer for the pick up of glue pellets for transfer via the air conduit. A vibrator imparts motion to the pellets to prevent bridging of same. Each hot melt tank includes a level switch with a probe which provides a signal to a control panel having relays which in turn actuate solenoid valves for the delivery of a pressurized air flow to one or more vacuum transducers. A portion of the pressurized air flow is bled off for supplying the vibrator in place on a base of the transducer assembly.

  • Patent number: 5346101
    Abstract: A sparger container comprises a pair of opposed end walls, a pair of opposed side walls, and a closed floor. The closed floor has an open-topped, longitudinally-extending channel and two generally planar sides slanting upwardly from the top edges of the channel to the side walls. A sparger system is provided immediately above the floor and includes a generally rectangular network of pipes disposed along the inner perimeter of the side and end walls, and at least one inlet providing fluid communication between a source of pressurized fluid and the pipes. The sparger system can also include a pipe positioned above the channel. Each of the pipes is provided with a plurality of holes therethrough, which are evenly-spaced circumferentially and are positioned at spaced intervals along the lengths of the pipes. An outlet for the container is positioned at one end of the channel and extends through one of the end walls.

  • Patent number: 5329660
    Abstract: A hand held pneumatic gun has an airway arranged to be coupled to a source of compressed air, the airway communicating with an air chamber via a trigger valve assembly. The gun includes a detachable breech that is supported in a sealed position against the air chamber by a support ring pivotally secured to the body of the gun. An interlocking assembly is arranged to interlock with the trigger valve assembly if the breech is not supported in its sealed position, so that actuation of the trigger valve assembly is inhibited unless the breech is sealed against the air chamber. The breech incorporates a nozzle that can be secured to an end of a hose or tube and a polymer projectile is placed into the breech to be forced by the air pressure through the hose or tube to clean the interior of the hose or to remove contaminate matter therefrom.

  • Patent number: 5322393
    Abstract: The present invention relates to a process for the removal of ore from the hold of a bulk carrier vessel. The prior art employes a boom mounted vacuum probe which is lowered into the ore material to effect unloading. This invention adds material handling hoses between the boom mounted vacuum probe and wheeled vehicles with attached aspirated suction nozzles. Further, the wheeled vehicles are powered from a stationary hydraulic pumping unit connected to the existing electric power of the boom mounted vacuum probe. Ore unloading efficiency is improved when the ore level in the hold reaches a depth of approximately two feet or less by providing wheeled vehicles carrying aspirated suction nozzles over the decking of the hold.

  • Patent number: 5238332
    Abstract: A device for handling bulk material, especially in marine transportation, comprises a pressure vessel having at least two members for mechanically enclosing a volume of the bulk material to be conveyed. The pressure vessel is equipped with pressure fluid activated push rods for moving the two members between an open and closed position to thereby grab a volume of the bulk material. The two members are preferably two essentially identical halves. A supply conduit is connected to the pressure vessel for supplying a pressurized gas thereto. A discharge conduit is connected to the pressure vessel for conveying the volume of bulk material out of the pressure vessel with the aid of the pressurized gas.

    Abstract: A disposable unit dose dispenser is provided for fluidizing and dispensing a predetermined quantity of powdered product, such as an antihistamine or a decongestant. The dispenser includes a first layer and a second layer connected together to form a gas chamber and a product reservoir adjacent one another. The product reservoir includes a delivery tube adapted to dispense the powdered product. The dispenser also includes a seal which separates the gas chamber from the product reservoir such that when pressure is applied to the gas chamber by squeezing the dispenser the seal ruptures causing a jet of gas to discharge from the gas chamber into the adjacent product reservoir fluidizing and dispensing substantially all of the powdered product from the product reservoir through the delivery tube.

  • Patent number: 5096337
    Abstract: A device achieves the entrainment of ultralight loose fill packing materials in an air stream to transport the packing materials into a depository for reuse or disposal. The device has an elongated air flow duct, with relatively low air flow induced by a rotating fan blade that extends partially into the interior of the duct. The construction provides for the air flow into the duct to be equal to the air flow out of the duct. A screen surrounds the fan blade to prevent contact with the packing materials as they flow through the duct. The collected packing materials are deposited into a flexible plastic bag, for example, that can be releasably secured to a perforated shroud on the outlet end portion of the transport duct. This device readily removes the loose fill packing materials from shipping cartons or, in the alternative, can recover widely scattered pieces of the material.
