Abstract:
A method and an industrial robotic device for uniformly applying coatings at appropriate thickness and pitch upon a surface moves a spray applicator foam dispenser between two parallel tracks. The uniform application of foam at each pass is assured, by accelerating the speed of the foam dispenser at the end of each pass, by providing respective curved uphill distal ends of the tracks, so that the spray applicator foam dispenser moves up the curved distal ends and returns quickly while changing speed tilt and direction at the end of each pass.
Abstract:
A tooling assembly 10 for use with apparatuses 12,54 for propelling a stream of particles at the tip 46 of a rotor blade, a stator vane is disclosed. Various construction details are developed which enable the use of the assembly with either apparatus. In one embodiment, the wall 36 of a rotatable fixture 32 shields part of the rotor blade or stator vane.
Abstract:
A double-nozzle deluge gun has a pair of nozzles arranged side by side rotatably on a rotatable table and an inter-nozzle control unit for adjusting the inter-nozzle angle measured between two lines obtained by projecting the radiation center lines of the nozzles onto a horizontal plane. Each nozzle has a deflector which is positioned in front of the nozzle during the very short range mode. Each deflector has a side cover which prevents water having passed through the deflector from excessively spreading sideways. The inter-nozzle angle and the water pressure are adjusted in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern in any range. Thus, the double-nozzle deluge gun can be controlled in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern having an appropriate width in any range.
Abstract:
A device for processing a concrete layer by water jets, comprising a jet tube on a carriage moveable to and fro along a guide. The jet tube is pivoted in planes substantially parallel to the guide and oscillates in planes making an angle with the guide. The jet tube is inclined in one direction along the extension of the guide during the movement of the carriage along the guide, and a control unit ensures that pivoting of the jet tube with an angular velocity leading to movement of a nozzle of the jet tube along the guide with a velocity substantially equal to the velocity of the carriage is initiated at the same time as the carriage is stopped in an end position, and the control unit starts the movement of the carriage in an opposite direction when the jet tube has finished its pivoting movement.
Abstract:
A spray nozzle system for vehicle washing apparatus is disclosed featuring a modular construction in which nearly identical base oscillating nozzle spray units are used for the sides, top, and front and rear nozzle sets. Each spray unit includes a bracket module and attached motor-drive module, and an additional bracket module can be connected end to end to create a doubling of nozzle sets in the unit. The bracket module rotatably supports a nozzle set mounting spray nozzle manifold shaft of either single or double length, supplied by a rotary fluid coupling clamped in a bracket included in each bracket module. The spray nozzle module shaft is oscillated by the motor drive module.
Abstract:
A nozzle arrangement for a high pressure jet for use in a device for treating surfaces by removing material from, roughening or cleaning such surfaces comprises a nozzle having an elongate body which is rotatable about its longitudinal axis. A nozzle head inclined at an angle of approximately 30.degree. to the longitudinal axis of the nozzle body communicates with the interior of the nozzle body and a high pressure pump is provided for generating a high pressure liquid jet to issue from the nozzle head. The nozzle head is maintained at a substantially constant distance from a planar surface to be treated and the nozzle body is reciprocated in partial rotations about its longitudinal axis in opposite directions to cause the high pressure jet issuing from the nozzle head to strike the surface to be treated with a recurring arc-shaped pivoting movement. The nozzle body has a toothed ring which is engaged by a toothed rack in order to impart partial rotations to the body and a further drive is provided by means of which further reciprocation of the nozzle body can be imposed on said partial rotational movement.
Abstract:
An automatic washing and sterilizing device for a stable comprising a crane moving on wire ropes, and a spray system mounted on the crane for spraying water for washing or sterilizing solution for sterilization all over in a stable.
Abstract:
The subject invention (1) provides a method and apparatus for cleaning the exterior of a sprayer in the area of its spray nozzle (2) and any existing air nozzles. The appropriate part (2) of the sprayer is inserted through an opening (4) in a container (3). All of the areas of the sprayer to be cleaned are directly charged with a cleaning fluid by a bow-shaped array of nozzles moving in a hemispherical path around the part (2) to be cleaned. The invention is particularly suited for the fully automatic cleaning of a spray gun mounted on a painting robot.
Abstract:
An automatic painting apparatus comprising a spraying booth having ceiling openings through which ventilating air is delivered to the spraying booth in downward laminar flows. The spraying booth houses a portal framework including a pair of vertical frames disposed on both sides of a conveying track of articles under a spraying treatment, and a cross frame extending between the vertical frames over and across the article conveying track. The cross frame carries spray guns for spraying paint downwardly. A spray gun moving mechanism connects the cross frame to the vertical frames to be dispaceable longitudinally of the cross frame. One of the vertical frames includes a cross frame drive mechanism for reciprocating the cross frame longitudinally thereof.
Abstract:
The invention is concerned with an hydration means for wetting the exposed surface of a core void formed on the withdrawal of a core former from a construction panel comprising compacted gypsum or like particulate materials, and proposes the free suspension of a reciprocable spray head by a flexible small-bore tube through which a setting liquid is applied to the spray head from a cross-head with which the tube is connected in fluid flow relationship. If necessary, the spray head may be weighted, while an apertured guide plate through which the tube passes may be provided above the upper limit of movement of the spray head.
