Abstract:
An electrostatic coating (atomizing) head is cleaned by ejecting an ejected steam stream to the electrostatic coating head to remove solidified mass of a coating solution deposited thereon.Ejecting is made via steam stream supply ports to forward and rear surfaces of the coating head without interrupting high voltage applied for coating or even during the coating operation. The method is suitable for aqueous coating solution.
Abstract:
Disclosed herein is an adjustable shower head apparatus having a digital clock incorporated therein. The shower head can be adjusted upward, downward, forward and backward in addition to the head itself which can be rotated forward and backward. The shower head arms have adjustable friction joints that will provide a fixed position of the shower head when placed anywhere within the boundaries of the shower head movement. A digital clock is mounted in the body of the shower head that can be easily seen by the person taking a shower. In one embodiment, both real time and elapsed time is available from viewing the shower head clock.
Abstract:
An apparatus which is adapted to move along a tundish, ladle, or the like having a generally closed lower end, enclosed sides, and an open upper end. The apparatus sprays the sides and lower end of the tundish with refractory material. The apparatus comprises a nozzle having an inlet and an outlet, and a base movable in an x direction generally horizontally along the tundish, a boom movable in a vertical y direction, a lance movable in a z direction generally perpendicular to the x and y directions, and a rotatably swivel bracket for rotating the nozzle outlet about an axis extending in the y direction. The apparatus also includes piping for supplying fluidized refractory material to the nozzle inlet, and a water ring for wetting the fluidized material before the nozzle outlet.
Abstract:
The assembly comprises a centrally-bored nozzle and centrally-bored nozzle body, the two being in substantially collinear alignment along a longitudinal axis, and a collar and locking ring, for swivelingly coupling the nozzle and body together, andd releasably locking the two together in selected, swiveled displacements from such alignment.
Abstract:
A device for positioning a number of working implements, for example spray nozzles, to certain working or treatment point on a car body as the latter is supported by an overhead conveyor for travel between different working and assembly stations on a production line. The device comprises a vertically movable base structure and a working implement carrying frame movably supported on the base structure. Hydraulic jacks on the base structure are arranged to accomplish a vertical parallel movement of the frame up towad the underside of the car body until one of four contact sensors indicate contact with the later. A final vertical adjustment of the frame is accomplished by four vertical cylinders which raise the frame in a non-parallel movement until at least three of the four contact sensors indicate contact with the car body. The docking of the frame to the car body is completed by activating two expandable dowels which are introduced into openings in the car body bottom shell. Thereby, the frame is arrested relative to the car body and the spray nozzles are activated to perform the intended treatment of the car body.
Abstract:
The Assembly comprises a centrally-bored nozzle, a centrally-bored nozzle body, and a centrally-bored jet orifice element, the three being in substantially collinear alignment along a longitudinal axis. The nozzle body has a spherical-shaped socket in which is received a spherical-shaped body portion of the element. Further, the element has a straight shank portion, extending from the body portion, which projects into a void in the nozzle body subsisting between the element and the nozzle. Adjustment screws, in penetration of the nozzle body, are arrayed about the shank portion for manipulation to adjust the attitude of the shank portion relative to the longitudinal axis.
Abstract:
A spraying device consists of a frame having an arm universally-pivoted thereon which has a spray nozzle at the outer end. The frame is designed to be supported on a forklift-type truck having a fork movable thereon. The frame has retaining elements for receiving and supporting the fork and the arm is received through pneumatic cylinders. The arm has first and second parts which are rotated relative to each other by a pneumatic motor.
Abstract:
A coating apparatus comprising a support assembly, a support moving mechanism for pivotally moving the support assembly about a horizontal axis, an applicator supported by the support assembly upwardly and downwardly movably, a position detector for detecting the raised or lowered position of the applicator, a pair of distance sensors attached to the support assembly and arranged one above the other at a distance for detecting the distance from the work surface to be coated, and a control unit connected to the position detector and to the distance sensors for causing the support moving mechanism to pivotally move the support assembly in response to detection signals from one of the distance sensors closer to the applicator to hold the applicator at a substantially constant distance from the work surface. Even when curved in the direction of the height, the work surface can be coated uniformly because the substantially constant distance is maintained between the applicator and the work surface.
Abstract:
In an apparatus which applies refractory material in either wet or dry form onto the inner surface of a furnace by means of a spray pipe, a rotating mechanism for rotating the spray pipe is provided with an automatic oscillating device for automatically effecting a continuous oscillation of the spray pipe, the continuous oscillation improving the operability of the spraying operation while uniformly applying an optimal amount of refractory material onto the inner surface of the furance.
Abstract:
The applicator includes two elongated conveyor rollers arranged in parallel alignment and inclined from a sealant application station toward a tire unloading station. The rollers simultaneously rotate a series of tires in the same direction about a common axis in side-by-side engagement with one end tire adjacent the sealant application station and the other end tire adjacent the unloading station. A kicker assembly unloads the latter end tire, whereupon the rollers advance the remaining tires toward the unloading station while maintaining coaxial rotation thereof. A fresh tire then may be positioned at the application station and the application and advancement steps repeated. The applicator further includes a sealant applicator for effecting airless spray application of sealant to a tire, together with a control system for controlling the position of the spray applicator and causing sealant to be purged a predetermined time after no sealant application is made. The applicator is suited for usage in a system for producing self-healing tires.
