Abstract: The present disclosure relates to a pneumatically driven pump for pumping a fluid. The pump may have a pump housing configured to receive a pressurized fluid signal. An inlet screen may be included at an end of the pump housing for admitting fluid therethrough into an interior area of the pump housing. An inlet casting may be included which is disposed within the pump housing adjacent the inlet screen. A poppet valve may be included which is configured to seat against the inlet casting. The poppet valve may have a propeller structure for creating a fluid pulse when the poppet valve seats, which helps to dislodge particles that have collected on the inlet screen, and thus help to maintain the inlet screen in a clean condition.

Abstract: The present disclosure is directed to a fluid separating flow nozzle which has a diffuser housing configured to be secured to a source of compressed fluid, and a diffuser element secured within a portion of the diffuser housing. The diffuser element may have at least one flow path opening forming a flow path through the flow nozzle, a nose portion and a moisture capturing area adjacent the nose portion for capturing moisture particles when a first airflow is directed through the flow nozzle in a first direction. A flow turning element may be incorporated which has a plurality of flow turning structures, and which is in communication with the flow path opening, and which imparts a turning motion to the first airflow and also to a second airflow flowing in a direction opposite to the first airflow. The turning motion helps to displace and eject moisture particles from the nose portion and from the moisture capturing area while the second airflow is occurring.

Abstract: Described herein is a transport tank trailer having a tank that can be used to more completely and effectively transport, store, load and unload a viscous product, such as a viscous liquid product, or liquid with solid(s) in suspension. Materials for transport, storing, loading and unloading include both food-grade and non-food grade products. Exemplary products include chocolate, paint, wastes, and asphalt. The tank system involves: a) agitation means (e.g., vibration devices) to force viscous product to flow during unloading; b) a heat-traced closed loop venting and unloading system resulting in the elimination of opening of the manhole on the tanker, which results in the release of heat; c) use of enhanced insulating materials to reduce product solidification during product discharge; and d) reduction of thermal bridges to increase product heat retention. The invention also involves an inventive cargo tank shape that promotes viscous product discharge during unloading of the tank.

Abstract: A valve including a valve body, the valve body providing an inlet and an outlet, a valve seat between the inlet and the outlet, a valve member, the valve member and valve seat being relatively movable to control flow through the valve, the valve member engaging the valve seat to prevent flow through the valve and disengaging from the valve seat to permit flow through the valve.

Abstract: A dispenser for dispensing pulverulent coating material includes an opening through which the pulverulent material is discharged and a conduit through which the pulverulent material is transported from a source to the opening. The conduit includes a section having a generally rectangular cross section transverse to the general direction of flow of the pulverulent material through the conduit.

Abstract: A dispensing device for dispensing a material. The dispensing device includes a somewhat cup-shaped interior opening in a first direction in which the material is to be dispensed from the dispensing device. The interior terminates at a discharge edge. The dispensing device further includes a skirt extending from the discharge edge in a second direction generally opposite the first direction. The skirt includes multiple passageways substantially equally spaced around a perimeter of the skirt.

Abstract: A dispenser includes an opening through which coating material is dispensed, a coupling for coupling the opening to a source of coating material to be dispensed, and a shroud for enclosing at least a portion of the dispenser. The shroud includes two portions which engage each other at first and second joints which extend generally longitudinally of the shroud.

Abstract: A method and apparatus for dispensing electrically charged particles of a coating material. A source provides the coating material to a coating material dispenser. An electrical supply supplies electrical charge. A first electrode provides charge to the coating material as it is dispensed. At least one second electrode is provided at a location removed from the first electrode. Both the first electrode and the at least one second electrode are coupled to the supply of electrical charge.

Abstract: A dispenser for dispensing pulverulent coating material includes an opening through which the pulverulent material is discharged and a conduit through which the pulverulent material is transported from a source to the opening. The conduit includes a seal member providing a lumen, a first member including a first reducer section including a lumen and a first feature and a second member including a first expander section including a lumen and a second feature. The first and second features cooperate to define a space for accommodating the seal member between the first reducer section and the first expander section. The conduit further includes a second reducer section and a second expander section.

Abstract: A dispensing apparatus is provided for a pulverulent material entrained in a stream of a transporting gas or mixture of gases. The apparatus includes a first member and a second member. The first member includes an interior into which the stream flows and a perimetral discharge edge. The second member includes a side facing the interior and a perimetral discharge edge. A discharge opening is defined between the discharge edges of the first and second members. A dimension of the discharge opening is determined by one or more third members. Each third member has a first end adjacent the first member and a second end adjacent the second member. The third members have non-uniform transverse sections. A transverse section of each third member between its first and second ends has a smaller area than the transverse section of each third member at one its first and second ends.
