Abstract:
A method and apparatus for coating a fiber used in oral hygiene. The method comprises aerosolizing a coating and projecting the aerosolized coating particles onto a target area of the fiber. The method also comprises recycling recaptured coating particles for reuse in fiber coating. An apparatus for coating oral hygiene fibers is also described.
Abstract:
An apparatus for applying a fluid to an outer surface of an elongated work piece having a longitudinal axis and a cross sectional shape, perpendicular to the longitudinal axis. The apparatus has a head member having an interior wall cross sectional shape adapted for receiving the cross sectional shape of the elongated work piece. The interior cross sectional shape defines an interior wall of the head member. The head member has an input end and an output end. The interior wall has means for applying the fluid to a surface of said elongated member. The head member has preferable a first part and a second part which are joined by an expandable member. The means for applying said fluid comprises a plurality of jets for directing said fluid on said surface and a plurality of output parts for recovering said fluid for applying a fluid to an outer surface, said elongated work piece having a longitudinal axis and a cross sectional shape, perpendicular to said longitudinal axis, comprising: a head member having an interior wall cross sectional shape adapted for receiving said cross sectional shape of said elongated work piece; said interior cross sectional shape defining an interior wall of said head member; said head member has an input end and an output end; said interior wall has means for applying said fluid to a surface of said elongated member.
Abstract:
A coating sprayer includes several sprayguns. The sprayguns are accommodated in an essentially solid-walled spraybooth. A conveyor with a motor-revolved belt conveys the articles through the spraybooth. A belt-wiping assembly extends across the belt and wipes its surface clean. The belt-wiping assembly includes a wiper that revolves around at least one axis. Since the axis is entirely or almost perpendicular to the surface of the belt, at least some of the wiper's active edge will contact the surface of the belt. The sprayer is intended for spraying such flat articles as furniture parts.
Abstract:
The present invention relates to a spraying apparatus and a method of using the same. The spraying apparatus can be used in the spraying of herbicides or insecticides from an aircraft or from the ground. The apparatus provides a separation chamber to remove the small drop component of the spray so that the component leaving the apparatus is essentially free of small drops. Small drops have slight fallspeeds and are subject to wind drift, causing off-target deposits and potential biological impact outside the treatment areas.
Abstract:
A recirculating sprayer adapted for mounting on a vehicle is improved for use at increased travel speed and for operation in higher wind conditions by angling the solid spray streams forwardly or rearwardly from a direction transverse to the travel direction. The sprays are employed in criss-cross, opposite pairs, with the spray stream patterns of adjacent pairs of spray nozzles abutting or overlapping one another for full coverage of all upstanding weeds or crops in an area traversed by the sprayer. A series of collector mats or panels may be arranged transverse to the travel direction, with sprays trained thereon for contacting each weed twice in its upstanding position once by each spray of a pair; the weeds may also be contacted once more as they are bent forward to pass beneath the panels and a reservoir thereunder. The collector may also be arranged in panels parallel to the travel direction, for increased ease in negotiating sloping terrain. Spray liquid is collected from the collector panel(s) into reservoirs therebelow and is recirculated for reuse.
Abstract:
Apparatus is disclosed having a centrifugal electrostatic atomizer pivotally mounted at the end of an extended arm, having variable atomization application positions, waste receptacle collector positioned beneath said atomizer, and pivotal mechanism for bringing the atomizer head to a position inside the receptacle for purging and solvent cleaning.
Abstract:
Apparatus for coating objects with an abrasive or corrosive fluid, for example, coating the surface of chill moulds with lime soup, is disclosed. The apparatus comprises a mixing tank having an impeller for feeding the fluid to an intermediate tank. A plurality of individually directed spray nozzles are arranged to spray fluid from the intermediate tank over the surfaces of inverted chill moulds. A collecting chute and purifying basin are provided for collecting the excess fluid and returning it to the mixing tank. Air is pumped into the bottom of the intermediate tank to prevent silting of the coating fluid.
Abstract:
A method and apparatus for applying a coating composition onto a web, in which the coating composition is subjected to a first general smoothing during the passage of the web between relatively stiff surfaces of a primary coating member and the final smoothing of the coating is effected in a nip formed between relatively flexible flat surfaces of a secondary coating member. Said coating members being spaced from each other in the running direction of the web. The web is both stabilised and pre-coated by the primary coating member, whereas the coating is finalised by the secondary coating member.
Abstract:
While being nonrotatably transported along a flight conveyor, glass containers are electrostatically treated with colored metal oxide film-forming organometallic compounds. The organometallic compounds are electrostatically sprayed in a nonflammable solvent system containing a halogenated solvent while a horizontal flow of air is provided across the flight conveyor in impinging relation with respect to the container being treated.
