  • Patent number: 10076760
    Abstract: A pneumatically powered foam sprayer is provided. The foam sprayer includes a spray hose having a spray nozzle, a trigger assembly proximate the spray nozzle, and a pressure-actuated valve responsive to the trigger assembly. An air conduit extends between the pressure-actuated valve and an opening in the trigger assembly. Obstructing the opening with a hand, a finger or a thumb creates a change of air pressure within the air conduit and actuates the pressure-actuated valve to selectively allow the supply of foam into the spray hose. The air conduit may extends longitudinally through an interior portion of the spray hose, or along an exterior portion of the spray hose, and can include a laminar, chemical-resistant outer surface. An internal pump is powered by compressed air through the pressure-actuated valve, and the spray nozzle remains open both during and between uses to prevent the accumulation of pressurized foam within the spray hose.

  • Patent number: 5203509
    Abstract: Apparatus for collecting, segmenting and conveying metal chips from machining operations utilizes a compressed gas driven vortex nozzle for receiving the chip and twisting it to cause the chip to segment through the application of torsional forces to the chip. The vortex nozzle is open ended and generally tubular in shape with a converging inlet end, a constant diameter throat section and a diverging exhaust end. Compressed gas is discharged through angled vortex ports in the nozzle throat section to create vortex flow in the nozzle and through an annular inlet at the entrance to the converging inlet end to create suction at the nozzle inlet and cause ambient air to enter the nozzle. The vortex flow in the nozzle causes the metal chip to segment and the segments thus formed to pass out of the discharge end of the nozzle where they are collected, cleaned and compacted as needed.

  • Patent number: 5186388
    Abstract: A process and apparatus are provided for injecting dry lightweight particulate material into a stream of catalyzed resin. The dry lightweight particulate material is stored in a fluidizing tank. The fluidized dry particles are conveyed from the tank under a controlled vacuum created by a low pressure venturi pump. An anti-static conveying tube delivers the dry lightweight particulate material to an adjustable delivery tube which terminates with a nozzle. The nozzle delivers a low velocity controlled spray pattern which coincides with the stream of pressurized resin. The nozzle is positioned at an acute angle relative to the longitudinal axis of the resin stream and injects the dry lightweight particulate material into the stream. Within the venturi pump and opposite to the main low pressure, low volume inlet, is a second pressurized inlet. This inlet directly controls the degree of vacuum, thereby precisely determining the amount of dry lightweight particles delivered to the resin stream.

  • Patent number: 4881856
    Abstract: A device for cleaning impacted material, such as wood chips in silos, utilizing a raking action of regularly spaced spikes and a flailing action of a hose with a jet stream nozzle. The device comprises a hose, connectable at a proximal end to a compressed air supply, and a nozzle connectable to a distal end of the hose, the compressed air being forced through the hose and out the nozzle to cause the nozzle and the hose to move under the influence of the expulsion of compressed air at the distal end of the hose. The spikes are attached along the hose to provide regularly spaced raking elements, and anti-kink mechanisms urge the hose into straight alignment. In operation, the nozzle is lowered into a silo in the vicinity of impacted material. Then compressed air is introduced into the hose and expelled out the nozzle in a jet stream thereby causing the hose and nozzle to undulate within the silo such that the spikes strike and dislodge the impacted material.
