An integrated liquidjet system capable of stripping, prepping and coating a part includes a cell defining an enclosure, a jig for holding the part inside the cell, an ultrasonic nozzle having an ultrasonic transducer for generating a pulsed liquidjet, a coating particle source for supplying coating particles to the nozzle, a pressurized liquid source for supplying the nozzle with a pressurized liquid to enable the nozzle to generate the pulsed liquidjet to sequentially strip, prep and coat the part, a high-voltage electrode and a ground electrode inside the nozzle for charging the coating particles, and a human-machine interface external to the cell for receiving user commands and for controlling the pulsed liquidjet exiting from the nozzle in response to the user commands.

A head is disclosed for use with a manufacturing system. The head may have a housing that discharges a tubular structure, and a cure enhancer connected to the housing and selectively activated to cure the tubular structure during discharge from the housing. The head may also have a nozzle that discharges a fill material into the cured tubular structure.

The disclosure relates to ultrahigh efficiency spray drying systems and processes, utilizing induction of localized turbulence in a drying fluid flow stream to produce spray dried product, having particular utility for low temperature spray drying operations. In a specific implementation, a method of processing a spray dryable liquid composition to form a spray dried product includes the steps of: generating a spray of the spray dryable liquid composition; contacting the spray of spray dryable liquid composition in a spray drying contact zone with a stream of primary drying fluid; injecting pressurized secondary drying fluid into the stream of primary drying fluid in the spray drying contact zone at multiple loci thereof to provide localized turbulence at said multiple loci; and recovering the spray dried product from the spray drying contact zone. Systems of the present disclosure are effective in achieving high-rate production of dry powder spray dried products, with substantially reduced capital equipment costs, energy requirements, and operating expenditures.

A surgical spray instrument is disclosed comprising a main body connectable to a transfer tube; a propellant actuator for selectively releasing propellant from the main body and along the transfer tube and out through a distal end thereof. An ion emitter is arranged along the tube, the ion emitter having an ion emission zone. This enables the directed and concentrated delivery of therapeutic, pharmacological and diagnostic agents to tissues inside or outside of the body. There is further disclosed a surgical assembly for enabling uniform deposition of a particulate material to a surface of an intracorporeal cavity of a patient. The surgical assembly comprises an ion emitter; a dispenser having an outlet locatable within the cavity and for dispensing the particulate material therefrom, and a processor for determining a location of the ion emission zone of the ion emitter in dependence upon the position of the outlet of the distributor within the cavity to provide for the uniform deposition.

Spraying heads may be used in spray guns for applying a pressurized aerosol material in the form of jets or spray. A spraying nozzle for spraying a polyurethane material includes a cylindrical body provided, on a first end, with a base having a mounting aperture extending into the cylindrical body, forming a cavity for arranging a head of a gun. The base of the nozzle is in the form of oppositely-disposed leaves. A second end of the body is provided with a cylindrical shoulder, a through-bore of which is communicated with a V-shaped and laterally non-closed recess at the region of an outlet of the sprayed material. Oppositely arranged plate-like protrusions adjoin a lateral surfaces of the cylindrical shoulder. A mounting aperture end which adjoins the base has a circumferential cut. The spraying nozzle is provided with an attachment means used when in an inoperative position.

A head is disclosed for use with a continuous manufacturing system. The head may have a housing, a fiber guide rotatably disposed at least partially inside the housing, and a diverter disposed at an end of the housing. The diverter may be configured to divert radially outward a matrix-coated fiber passing through the fiber guide.

A suspension plasma spray deposition system comprising a suspension plasma spray device configured to deposit coating material on a surface of a component. The surface of the component includes a plurality of apertures. The system further includes a fluid flow system configured to flow fluid through the plurality of apertures in the surface of the component to reduce deposition of coating material in plurality of apertures. The fluid flow through each respective aperture of the plurality of apertures in the surface of the component is between about 0.095 and about 0.200 cubic feet per minute (cfm).

A spray nozzle assembly is provided with an electrode, a wear resistant member, and a compliant sleeve. The wear resistant member supports the electrode and is supported by the compliant sleeve. For coating operations that use abrasive powder such as porcelain enamel, the wear resistant member may comprise ceramic. The compliant sleeve may be made of an elastic material such as plastic, which allows one end of the compliant sleeve to receive an end of a glass powder tube. The wear resistant member may be in the form of a ceramic spider. The electrode may be installed in-line with a powder flow path defined by the powder tube, which extends through a spray gun body.

A head is disclosed for use with a continuous manufacturing system. The head may have a housing configured to receive a matrix and a continuous fiber, and a diverter located at an end of the housing. The diverter may be configured to divert radially outward a matrix-coated fiber. The head may also include a cutoff having an edge configured to press the matrix-coated fiber against the diverter.
