Abstract:
A tube bundle cleaner capable of cleaning vertical tube bundles by remote actuation by an operator is provided. To prevent binding of the flexible fluid supply conduit which supplies hydroblasting fluid to the manifold upon which the cleaning lances are mounted, a bight portion of the conduit extends toward the open end of the housing which slidably carries the manifold.
Abstract:
A portable spray apparatus including a bottle reservoir for holding fluid, a manually actuatable pump secured to the bottle reservoir, and an elongated fluid conveying tube having one end connected to the output of the pump and being in the form of a flexible loop section and an elongated output section, wherein the loop section is between the pump output and the output section. The output section of the tube is supported by an arm assembly that is pivotally supported by a support rack which allows the support arm to be positioned at different angular positions.
Abstract:
A fuel nozzle for injecting atomized fuel into an air stream at an adjustable angle with respect to its longitudinal axis is described incorporating a support flange, a fuel supply tube, a nozzle tip body at the end of the fuel supply tube and a sheath between the support flange and the nozzle tip body for directing air to the nozzle tip body. A second sheath enclosing the first sheath is provided wherein each has a slot opening which may be positioned with respect to the support flange for admitting air into and where the size of the opening may be controlled by rotating the outer sheath with respect to the inner sheath to provide an adjustable overlap of the slot openings. The invention overcomes the problem of injecting fuel into the combustor of a jet engine at an angle which may be adjustable over a predetermined range to enhance combustion of the fuel. The invention further overcomes the problem of injecting or capturing a predetermined amount of compressor discharge air for subsequent flow to the nozzle tip.
Abstract:
A novel and improved airbrush support and guidance apparatus which permits an airbrush to be held at a uniform standoff distance and at a preselected orientation with respect to a workpiece surface while traversing the workpiece surface in a preselected path of travel including freehand or generally curvilinear paths of travel, as well as, linear, and circular arc paths of travel, while maintaining a uniform standoff and orientation respect to the workpiece surface to provide for increased precision in the rendering of airbrush artwork.
Abstract:
A spray gun is designed for mounting on the end of a robot arm. The construction of the gun is provided such that nearly all of the main components with the exception of the spray head itself are located in a main body to which is mounted a pivotal spray head assembly which may pivot approximately 90.degree. to either side of the normal straight-ahead position. The power supply and power generating units are located in the main body. The electrostatic power supply connection to the spray head enters the spray head shaft on the opposite side from the fluid supply entry. The fluid control valve may be located in the spray head shaft.
Abstract:
A device (16) for diverting and diffusing flushing water from a source such as a hydrant (10) includes a swivel (46) attachable to a spout (12) of a hydrant (10) and a discharge member (18) carried by the swivel (46) for rotation about a first axis (30). The discharge member (18) has a first portion (26) aligned with the first axis (30) and a second portion (28) aligned along a second axis (32) which intersects the first axis (30) at an acute angle. As the discharge member (18) is rotated about the first axis (30) within the swivel (46), the direction of the discharge of liquid through an internal passageway (22) formed in the member (18) will vary.
Abstract:
A fluid pressure activated mechanism in a rollable side wheel irrigating device allows gravity to maintain the sprinkler head portion of the device perpendicular or level to the ground as the device is rolled in position, and prevents nozzle pressure from moving the sprinkler head once fluid has entered the irrigation device after it has been positioned. The side wheel irrigating device includes an irrigation conduit within a horizontally-disposed axle member attached to two wheels. The conduit extends through the axle at its mid-point and routes irrigating fluid to a gravity-biased sprinkler conduit supporting a sprinkler head. The mechanism is attached between the two conduits, with the mechanism being rigidly attached to the irrigation conduit. The sprinkler conduit is attached to an annular hub and allowed rotative and translative movement in the mechanism housing. Prior to fluid of sufficient pressure entering the mechanism housing, the sprinkler conduit is free to rotate under the force of gravity. As fluid enters the housing, a pressure differential is created across the annular hub as the fluid pressure on the housing inlet side of the hub increases relative to the atmospheric pressure on the housing outlet side of the hub. The pressure differential thereafter causes the axial translation of the hub until a sharp ridge of the hub frictionally engages a rubber washer. The frictional engagement prevents rotation of the sprinkler conduit, and thus of the sprinkler head, as long as the flow of irrigation fluid continues.
Abstract:
An apparatus and method for the controlled, intermittent, automatic dispensing of atomized fluid, such as an insecticide, into a use area, such as a barn, characterized in that the apparatus and its method of use are controlled to dispense fluid approved for use in the particular use area and supplied from an approved container provided with a vented fluid outlet and dispenser having a code cooperating with a code of a fluid inlet and dispenser means associated with the apparatus. The code includes mating key chambers and key pins arranged in a selected code for a selected approved fluid.
Abstract:
Apparatus for moving a reciprocating fluid-emission head automatically through successive, variable-speed, variable-function operating cycles that include linear extension and retraction to and from a space within which predetermined operations are to be sequentially performed. The apparatus has an elongated fixed frame, an intermediate carriage on the frame and a head carriage on the intermediate carriage, the head carriage being adapted to support the fluid emission head. The carriages are moved simultaneously between a retracted position coextensive with the frame and an extended position by chain and sprocket drive, the maximum extension of the fluid emission head being about twice the length of the frame due to the double extension achieved by extending both carriages simultaneously. A plurality of fluids to be sprayed (including, e.g. liquid lubricant) are transmitted from a manifold block on the fixed frame to the reciprocating emission head by a plurality of inflexible, extensible fluid conduits. The operation of the apparatus is controlled by means of pulses generated in response to motion of the chain and sprocket drive for the carriages and by a pulse counter adapted to count the pulses being generated and to count a plurality of preset position representative totals.
Abstract:
A method and a device for swivelling a spray nozzle, especially for spraying concrete, over a sector between two turning positions. The speed of the swivelling movement is kept constant, regardless of the nozzle attitude. By overriding an automatic swivel control unit, the turning positions can be replaced, and once the override ceases, automatic swivelling resumes between the new turning positions.
