Abstract: The gun comprises a body having a downwardly extending grip (2) and an assembly comprising a heating block (4) having a vertical axis, a first envelope (5) defining with the block a sinuous path for heating air, and a second envelope (6) defining a path for paint. The second envelope (6) is in the shape of a bell and is pivotally mounted on top of and around the first envelope (5). The first envelope (5) and second envelope (6) define therebetween a chamber (45) which communicates with the paint path and has an outlet conduit (46) which extends through the heating block (4) and communicates with a rotary spraying head (T) mounted on the front end of the body (1). A vertical hot air passageway (28) coaxially surrounds the outlet conduit (46) and communicates with the sinuous path for heating air and also communicates with the spraying head. The second envelope (6) has a lateral boss (39) defining a passage which communicates with the path for the paint.

Abstract: A portable, self-contained unit for the application of textured wall and ceiling covering material comprises a pressure tank adapted to be charged from an external source or by a manually actuatable pump incorporated in the tank. A pressure line containing a regulator connects the tank to an applicator gun having a longitudinally displaceable nozzle which directs the pressurized air across the bottom of a hopper containing textured material. Various tips for the gun are available to control the amount and texture of the material applied.

Abstract: A jet carrier assembly for cleaning well liners has a jet tool stabilized by a centralizer proximate to each of the tool's upper and lower ends. The jet tool is an elongate member having about 4 to 8 pairs of jet nozzles axially spaced therebetween, the axial spacing between alternate pairs being equal. The jet nozzles are spaced to provide a jet fluid track that covers any given point on the liner at least once but not more than twice when the member is lifted at a constant selected vertical speed and a constant selected rotational speed. The nozzles are mounted within adapters which are in turn detachably mounted to the elongate member. The adapters, which are provided in various sizes depending upon the diameter of the well liner, are interchangeable. The centralizers are capable of axial and rotational movement along mandrels attached to the upper and lower ends of the tool.

Abstract: The disclosure is directed to a center pivot irrigation system capable of operation under high or low water pressure and a constant volume sprinkler head therefor, which together provide uniform water distribution over an agricultural field notwithstanding the presence of hills and valleys in the field, pressure fluctuations of the water source, friction losses or the direction or magnitude of the wind. The system employs a plurality of sprinkler heads each of which provides a constant volume of water to the annular area over which it travels. Because the annular areas increase in size and total water requirements with increasing distance from the center pivot, the water delivering capacity of each sprinkler head is chosen as a direct function of its radial distance from the center pivot, thus insuring the same water distribution to all points on the field. Each sprinkler head is designed to produce a spray pattern that extends laterally outward with a predetermined directional orientation.

Abstract: A connecting device for connecting a water hose to an object. It includes at least two pieces, of which one is connected to the water hose and the second to the object. The first connecting piece consists of a hand shower, part of which is a handle and part a shower head. The hand shower contains a valve device having a valve body which is moveable between at least two positions, and which is designed to be moved to a connected position by means of the second connecting piece. The valve is designed to then allow water to flow from the hand shower to the object while preventing water flow out of the shower head; but the valve allows water to flow from the shower head when the valve body is in its normal non-connected position.

Abstract: A spray dispenser including a hollow casing, having sockets in each of which a pair of O-ring seals is mounted. A ball valve is urged toward one of the O-ring seals of each socket. A housing is removably mounted in the casing. Hollow lugs on the housing each having a cylindrical outer face are received inside O-ring seals in sealing relation therewith. Each lug unseats the associated ball valve. When the housing is removed, the ball valve seats against one O-ring seal when the housing is removed from the casing while the lug is in sealing engagement with the other O-ring seal. Compressed air and liquid under pressure are directed through the sockets to a dispensing valve member on the housing, and the pressure need not be released when the housing is removed.
