Abstract: An apparatus for applying spray texture to a wall or the like. The apparatus comprises an aerosol can containing pressurized spray texture material. The spray texture material is released from the can by a valve and passes through a nozzle passageway, out of a discharge opening, and on to a surface to be textured. The apparatus further comprises a flexible member that is aligned with the nozzle passageway that allows the effective cross-sectional area of the discharge opening to be varied. This flexible member defines a central bore that defines the cross-sectional area of the discharge opening, and deforming the flexible member changes this cross-sectional area. A mounting assembly is provided that mounts the flexible member onto the actuator member in a manner that aligns the central bore with the nozzle passageway and allows the deformation of the flexible member.

Abstract: A method for applying a spray texture material to a wall surface utilizing an aerosol container for the texture material, along with discharge tubes through which the material is dispensed. By using tubes of different cross-sectional area, the spray patterns of the material can be made with smaller and larger particle size within more precisely controlled limits.

Abstract: A magnetic paint composition comprising a carrier, particulate magnetically permeable material, a binder, and a thickening agent having thixotropic and viscosity characteristics such that the paint composition has high viscosity when stationary, and low viscosity when shear forces to the paint composition, as it is being applied to a wall surface. When the paint is dried, magnetic objects can be mounted to the wall surface and held in place by the interaction by the magnetically permeable material.

Abstract: An aerosol spray texture apparatus to dispense a spray texture material having particulate matter therein against a ceiling or other surface. There is a container having a spray texture material in the lower portion thereof, and inert compressed gas in the upper part of the container. A dispensing valve at the top of the container is depressed to cause the spray texture material to travel upwardly through a dispensing tube and from the valve onto the ceiling surface.

Abstract: A face mask assembly and method of use having a housing and a replaceable filter mounted in said housing. A fan means draws air into a plenum chamber defined by said housing and said filter for this air to pass into a facial breathing area. An outlet check valve is provided, and a primary filter through which air passes before entering said plenum chamber.

Abstract: A spray applicator to discharge plaster or another texturizing material in a spray pattern against a wall surface or the like. There is a manually operable air cylinder and piston assembly which discharges pressurized air through a first nozzle, with an air jet traveling through an area where the plaster or the material descends from a container, with the air jet carrying some of the plaster through a forward discharge nozzle to cause a spray pattern. There is rotatable fluid discharge nozzle portion which is, by said rotation, moved toward and away from an air discharge nozzle.

Abstract: A dry wall tape applicator where the tape moves through a chamber containing a taping compound and out a dispensing opening to a seam defined by two drywall panels. The dispensing opening is formed in part by an adjustably mounted plate, the position of which is controlled by a rotatable knob having an eccentric actuating stud member engaging a slot of the plate. The plate is held within close tolerances in a slideway so that the dispensing opening defines an accurately controlled slot of uniform width. The bottom wall of the housing has a convex configuration so that when the tape is in close proximity to the bottom wall, there is a proper application of the taping compound to the tape.

Abstract: A spray applicator to discharge plaster or another texturizing material in a spray pattern against a wall surface or the like. There is a manually operated air cylinder and piston assembly which discharges pressurized air through a first nozzle, with an air jet traveling through an area where the plaster or the material descends from a container, with the air jet carrying some of the plaster through a forward discharge nozzle to cause a spray pattern. There is a rotatable adjusting sleeve which moves the two nozzles further apart or closer together to control the spray pattern and also to close the discharge nozzle.

Abstract: A manually operated spray applicator to deposit plaster or the like against a wall surface in a spray pattern. There is a forward containing chamber for the plaster, a rear pressurizing chamber to supply the pressurized air through a discharge stem, and an intermediate positioning chamber having a moveable piston which moves the discharge stem between its open and closed positions. There is a control valve which is operable by a trigger which selectively vents a bypass passageway that pressurizes the positioning chamber to move the discharge stem between its open and closed positions.

Abstract: A painting system having a supply section, a delivery and control section, and an applicator section. The supply section comprises a peristaltic type pump. The delivery and control section comprises a unitary tube having a delivery passageway and an air pressurizing passageway. A pressurizing control switch at the location of the applicator acts through the air passageway to control operation of the pump. The applicator section has a housing which provides a uniform pattern of distribution passageways for uniform application of paint.

Abstract: A manually-operated spray applicator for discharging a coating fluid is comprised of a receiving chamber having inlet and outlet ports for respectively admitting and discharging coating fluid under pressure developed by a jet of air issuing slightly upstream of the receiving chamber and created upon the manual stroke of an air-compression piston; a closed compression chamber isolated from the receiving chamber within which the airjet is developed; and a stroke-responsive sealing stem having a central airway with an air jet orifice in registration with the discharge area of the outlet port, which airway is in communication with the compression chamber; wherein the sealing stem is adjustably reciprocable along a line from a biased sealing position closing the outlet port at the beginning of a stroke on the piston, to a retracted position with the airjet removed to a preselected position slightly upstream of the outlet wherein the sealing stem returns to its sealing position prior to the completion of that strok

Abstract: Methods are disclosed for externally and conductively heating at least a portion of the sole of a ski boot and for convectively heating substantially the entire inner surface of the ski boot while the ski boot is firmly, but removably, clamped against a flat surface with the flat sole of the ski boot in extensive surface-to-surface contact therewith so as to permit drying of wet boots, warming of cold boots, and/or softening of the molded foam interiors of the boots, to render such boots more comfortable while maintaining the flat sole of the ski boot rigidly clamped in a flat planar condition to prevent warpage thereof. In a preferred form of the invention, methods are disclosed for externally and conductively heating at least a portion of the sole of each of a pair of ski boots removably carried by, and clamped to, a boot and shoe tree and for simultaneously convectively heating the inner surfaces of both ski boots.
