Abstract: The improved traveling spray assembly and washing method includes a vertical header pipe mounted on tracks that run the length of the bank of collector plate electrodes. The header bears a plurality of nozzles directed to spray washing fluid onto the collector plate electrodes for their washing. A horizontal supply pipe is mounted along the top or the bottom of the electrostatic precipitator and extends to about the mid-point of the bank of collector plate electrodes. The horizontal supply pipe is connectable outside the electrostatic precipitator to a source of washing fluid. A pair of pivotally-connected pipes next are provided. One of the pipes is pivotally connected to the end of the supply pipe at the mid-point of the bank of collector plate electrodes and extends to a position opposite the supply pipe at either the bottom or top of the electrostatic precipitator. The other pipe extends back to the side of the supply pipe and is pivotally-connected to the header pipe.

Abstract: A pneumatic nozzle for use in an apparatus for cleaning textile machines comprises a frustum-shaped flattened tubular body made of a flexible material. The tubular body is inflatable upon flow of pressurized air therethrough whereat the tubular body takes a straight position, and deflatable upon ceasing of air flow therethrough whereat the tubular body takes a fall-down position. A neck is formed at one of the opposite ends of the tubular body and is associated with retaining and coating rings for securing the nozzle in a wall of blowing hose apparatus of the cleaning apparatus.

Abstract: The present invention relates to an automatic spray painting machine comprising a first movable portion movable in a direction toward and away from a work object, a second movable portion movable in a specified direction perpendicular to the moving direction of the first movable portion, a supporting portion for supporting a spray nozzle, a first actuator for moving the first movable portion, and a second actuator for moving the second movable portion. The first and second actuators are mounted on the supporting portion. The automatic spray painting machine further includes a transmission mechanism for transmitting drive of the actuator to the movable portion positioned closer to the spray nozzle in the supporting order effects drive transmission, with the other movable portion positioned closer to the supporting portion in the supporting order being allowed to move.

Abstract: An apparatus and method for removing concrete from a ceiling surface by hydrodemolition which includes a mobile truck unit adapted for movement along a floor surface or the like and which supports a pair of upstanding telescoping support arms having an elongated boom mounted at their upper ends in a manner to enable selective orientation of the boom relative to a ceiling surface. A carriage is mounted for reciprocating movement along the boom and carries an upwardly directed lance and discharge nozzle operative to discharge high pressure fluid, such as water, against a ceiling surface such that selective movement of the nozzle and mobile truck during high pressure fluid discharge are operative to remove concrete from the ceiling surface.

Abstract: An automatic coating apparatus has a plurality of nozzle devices movable in X-, Y-, and Z-axis directions along tracks over a workpiece to be coated. One of the nozzle devices is displaceable with respect to the other nozzle device. Different coating materials are ejected from the nozzle devices toward the workpiece. Each of the nozzle devices has a nozzle which can be opened and closed by a valve operated by a cylinder mechanism. While a coating material is being ejected from one of the nozzle devices, the other nozzle device is closed. By thus selectively opening and closing the nozzle devices, the different coating materials can be coated successively on the workpiece.

Abstract: Cleansing apparatus comprising a pair of rotating cylinders with spray nozzles in the walls thereof. The cylinders provide cylindrical cleansing chambers which have their axes displaced from each other at an angle of approximately 30 degrees to comfortably receive the hands and forearms of a user. Certain of the nozzles in each cylinder are disposed in a helical array to sweep the forearm of the user with cleansing fluid as the cylinder is rotated. Each cylinder preferably has an inner liner and an outer liner with space there between providing a passageway for cleansing fluid to the nozzles which are preferably formed in the inner liner. An elastomeric support for each cylinder is provided. A blower may be associated with the cylinders for drawing air into the cylinders to reduce external splashing of cleansing fluid.

Abstract: A self-propelled, linear-forwardly, relatively slow-moving irrigating apparatus has a main frame and master drive unit carrying a rotating, water-supplying, pipe-like, axle shaft that provides a side-extending wheel-line along which are spaced what may be termed power, booster and wheeled spray units that enable a large area of ground crop to be irrigated at one time. Longitudinally spaced-apart hydrants are provided along the length of the field that is to be irrigated to detachably receive a flexible water-supplying hose that is also detachably carried by the main frame. The apparatus has automatic means for maintaining the main frame and the wheel-line in an aligned forwardly advancing relation, for stopping forward movement when a serious obstruction is encountered and when the desired full extent of its advance along a side-extending anchored guide cable has been attained.

Abstract: A programmable sprinkler system ideally suited for use in an enclosure such as a nursery and/or arboretum includes a first overhead rail and a water pipe connected to a pressurized source of water. The water pipe is provided with a plurality of water valves placed at discreet intervals along its length and extend outwardly therefrom and is positioned alongside and close to the first overhead rail and parallel thereto. A source of electrical power is positioned close to and generally parallel with the first rail on the other side thereof and extends essentially its entire length. A plurality of second overhead rails have one end of each positioned near the valves and the first rail and extends outwardly therefrom, preferably at right angles thereto, defining a path along which the water is to be dispensed. A carrier mechanism rests on the first rail. Nested upon the carrier mechanism is a detachable car that includes a second coupling device to bring electrical power to it.
