Abstract: A texture material applicator and a method for applying texture material to a wall or ceiling surface to produce a desired surface texture and appearance. A selected one of several different rotary dispenser inserts is rotated within a chamber in a body of the applicator, picking up a quantity of texture material on each of a plurality of spatter elements. The spatter elements are resiliently bent by a regulator and throw bits or drops of texture material out from the chamber and radially outward through an outlet opening in the body of the applicator as the spatter elements spring away from a release edge of the regulator. Different textures may be provided by using different rotary dispenser inserts having different spatter elements differently located on the rotary dispenser.

Abstract: The apparatus has as many invalidating units (E) arranged next to one another as there are longitudinal rows of security prints on the print carriers (P). Each invalidating unit (E) has a stand (1), a trough (3) vertically displaceable in the latter and intended for receiving ink (4), a centrifugal wheel (7) rotating continuously above the trough (3), and a shutter (11) which interacts with an orifice (10) of a cowl (9) covering the centrifugal wheel (7). By means of a controlled actuating member (6), the trough (3) is adjustable between a raised working position, in which the centrifugal wheel (7) dips into the ink and the shutter (11) exposes the orifice (10), and a lowered position of rest, in which the centrifugal wheel (7) does not dip into the ink and the orifice (10) is covered by the shutter (11).

Abstract: An apparatus for producing small clear ice bodies includes an evaporator (110) having freezer cells (12) open at the bottom and cooled by a refrigerant pipe (11). Interspaces between the freezer cells (12) are covered by strips (114) of insulating material. On the outside of the insulating material (114) defrosting components are arranged, formed of metal strips (17). Water is sprayed upwardly out of a trough (30) into the freezer cells by means of a spraying device (20) in the form of a bucket wheel rotatable about a horizontal shaft (29). The bucket wheel has two spaced parallel circular discs (28) with concave splash blades (27) arranged between them. The water sprayed upwardly keeps the metal strips (17) at above-freezing temperatures, so that ice layers cannot form and interconnect the small ice bodies. Splash-guard walls (33), as well as a movable splash-guard flap (32), prevent the escape of water from the apparatus. When defrosted, small ice bodies (1) fall onto an inclined grid (36).

Abstract: An apparatus for filtering, washing and cooling gases, wherein gas is forced through a foraminous wall extending across a chamber and water is sprayed across the chamber on the upstream side of the wall to filter, wash and cool the gas, employs as the water sprayer a rotating disc bearing projections which scoop up relatively large amounts of liquid and cast it against an atomizing member. The impact of the liquid on the atomizing member breaks the liquid into small droplets and produces a uniform spray.

Friction rollers are fixed at either end of the stabilizer axle, spring-biased into engagement with an interior surface of the dishwasher cabinet, the constrained simultaneous rotation of each wheel serving to precisely control the movement and attitude of the rack during in and out movement. The spring-bias also preloads the rack mounting components to provide a vertical stabilizing effect. The stabilizer axle is mounted to specially configured rear corner brackets, housing spring-biased plungers which rotatably mount the axle, while producing the upward biasing thereof.

Abstract: An improved liquid aerating rotor assembly comprises a support frame having a rotor mounted for rotation about a horizontal axis. A plurality of floats support the rotor and support frame on the surface of a sewage pond or the like. A V-shaped deflecting plow or V-shaped front float is located upstream of the rotor. This configuration causes the upstream surface layer of liquid to pass around the rotor. This prevents any solid debris located in the surface layer of liquid from jamming the rotor and allows more complete aeration of sub-surface liquid. Alternatively, a scoop may replace the V-shaped deflecting members.

Abstract: A method for coating with a liquid the window panel of a display tube by means of at least one brush mounted for rotation in a reservoir containing the liquid. As the partially submerged brush is rotated about its axis, drops of liquid picked up by the brush hairs are flung against the window panel. This method results in continuous mixing of the coating material and the return of the excess coating liquid back into the reservoir so that losses of the coating material are minimized.

Abstract: A hand-operated liquid spray apparatus operates on the air-lift pump principle wherein the air-forcing member and the spray-forming member are one and the same. Such an apparatus requires no nozzles or valves and no permanent pressurization of the sprayed liquid. A plurality of deflectable vanes are movably disposed in an open-ended chamber which communicates with the interior of a liquid container via separate air and liquid passages. The vanes, when at rest, seal both passages from the open chamber end. Operator-initiated motion of the vanes toward the air passage forces air trapped in the chamber through the air passage and into the container, thereby forcing liquid up through the liquid passage to wet the vanes in the chamber. A lip at the open end of the chamber is arranged to deflect the wetted vanes as they move past the lip. After passing the lip the deflected vanes spring back to their undeflected positions and, in so doing, throw off a spray pattern of liquid droplets.

Abstract: A generally cup-shaped fuel slinger concentrically secured by its base portion to a rotatable shaft located in a combustion chamber and having a radially inwardly extending lip at its open end provided with a plurality of circumferentially spaced notches opening toward the shaft and spaced at their bottommost portion from the inner annular surface of the slinger side wall. Fuel is delivered by a single tube through the open end of the slinger and is centrifuged outwardly against the inner annular surface of the slinger side wall, and thereafter delivered from the slinger to the combustion chamber through the notches. The slinger is located between a radial turbine and a compressor of a gas turbine engine. The fuel supply tube projects axially through a vane in the diffuser, radially along the diffuser, and then axially into the fuel slinger between the lip and the outer periphery of the adjacent shaft portion. In the disclosed embodiment the notches are generally V-shaped.

Abstract: A large scale liquid cooling assembly has two stages for air cooling of hot liquid. Each stage has a plurality of liquid spray units for selective controlled projection of liquid drops in at least one trajectory extending generally perpendicular from its unit and in a common horizontal direction therefrom. The drop sizes, velocities and volume rates of the liquid spraying are adapted to provide a directional wind effect across the unit along the common horizontal direction. The water can be initially cooled in the first stage, and subsequently further cooled in the second stage. At least some of the units of the second stage are adjacent some of the units of the first stage, and create directional wind effects complementary to the directional wind effect of the first stage.The alignment of the liquid spray units in the two stages can take several different forms.

Abstract: An apparatus for filtering, washing and cooling gases including a chamber having inlet ducting and outlet ducting. Gases conducted through the inlet ducting into the chamber are cleaned and cooled therein and removed through the outlet ducting. Within the chamber is a convoluted foraminous wall extending transverse to the direction of gas flow to maximize the area where water droplets will impinge and vaporize. Some means such as a fan is used to force the gas through the foraminous wall. A pool of water stands in the bottom of the chamber between the inlet ducting and foraminous wall and a curtain of said water is sprayed from said pool by means of rotating discs and directional control mechanisms, whereby gas entering the chamber passes through the water curtain and is cleaned and cooled.
