An adaptive hot melt feed system includes a melt system, a feed system, a gas control device, a sensor, and a controller. The melt system includes a heated vessel. The feed system is configured to deliver a solid material to the vessel of the melt system for melting. The gas control device is configured to control a supply of gas provided to the feed system to drive the solid material from the feed system to the melt system. The sensor can be configured to detect an amount of material in the vessel of the melt system. The controller is in electronic communication with the gas control device and is programmed to signal the gas control device to vary the supply of gas to the feed system based on a fill metric determined by the controller.

Apparatus for blending and applying plural substances including aggregate onto an environmental substrate is shown and described. The apparatus includes optionally a single power plant, plural pumps each fed by a respective hopper, and a blender blending pumped materials together. Dispensing ratios of the two pumps are mutually adjustable. An onboard air compressor delivers compressed air for atomizing blended materials as they are dispensed with the aggregate. Because materials may be curable or hardenable, flushing is enabled. The apparatus may be a free standing wheeled device.

The invention relates to a separating powder filter, particularly for supplying different types and/or sorts of powder, as selected, to a powder delivery device. The separating powder filter comprises the following: a first powder inlet, at least one additional, second powder inlet, and a powder outlet. Either the first powder inlet or the at least one second powder inlet can be fluidically connected to the powder outlet of the separating powder filter.

A method and a dense phase powder pump for conveying coating powder from a first powder reservoir to a second downstream powder reservoir or to a downstream powder spray-coating gun or the like installation for spraying coating powder are disclosed. In order to reduce the number of components of the dense phase powder pump that require maintenance, the dense phase powder pump is designed as a single-chamber dense phase powder pump and has only a single powder conveyor chamber for conveying coating powder.

A distribution system for delivering preheated epoxy material for spray application includes a bundle of lines that terminate on their far end in a manifold. The distribution system is uniquely constructed in a manner such that it delivers the correct materials individually to the manifold while maintaining separate flows of the materials. This separation of the materials until ready for spraying prevents mixing of the two-part epoxy which at the elevated delivery temperatures would result in early curing of the epoxy within the delivery system itself. The bundle of lines contains at least one and preferably two base epoxy delivery lines, at least one catalyst delivery line and at least one heating circuit. The manifold terminates in a static mixer that in turn delivers the mixed epoxy to a spray head for spray application to the substrate.

A medical powder spraying device with easy control of the flow volume of the powder being sprayed and an operating method of the powder spraying device are disclosed. The powder spraying device is characterized by including a flow volume control means, and thus the flow volume of the powder being sprayed may be more easily controlled.

A stand for holding a cylindrical receptacle at an angle including a first support, a second support positioned at an angle X in relation to first support and associated with first support at a vertex and a base, the base uniting the first support and the second support.

The disclosure relates to a coating agent valve for controlling a stream of a coating agent in an application device, in particular in an atomiser, having a movable valve element (2) which controls the stream of coating agent dependent on its position. The disclosure provides for the valve element (2) to be rotatable.

A hopper type agricultural and livestock spreader and fertilizer dispensing apparatus. The dispenser may be configured to be mounted to a ground transport vehicle, such as a tractor and three point hitch. An auxiliary outlet is configured in the hopper at an elevated position from a bottom end thereof. A flow regulator is operatively attached to regulate the outlet area of the auxiliary outlet to achieve a desired flow rate. The auxiliary outlet is dimensioned to permit the flow of large feed stocks. A dispenser flow tube may be operatively connected to the outlet to direct the flow of feed product in a desired spot. The flow tube may extend laterally from the side edges of the hopper to permit delivery of food product along the length of a livestock feed trough. A kit for modifying a hopper type fertilizer/feed dispenser.

Various embodiments disclosed relate to a method of cold-spray deposition involving cooling the cold-spray nozzle by at least one of expanding and vaporizing a compressed cooling fluid in proximity to the cold-spray nozzle. The present disclosure also includes a cold-spray deposition spray head, a cooling jacket for a cold-spray deposition nozzle and a cold-spray deposition system comprising the same.
