Abstract: An aerosol composition for producing a surface having an abrasive grit adhered thereto, which composition can be dispensed from a suitable aerosol container, said composition comprising abrasive grit, a binder solution which is suitable for affixing said grit onto the surface comprising a polymeric resin and an organic solvent which dissolves said resin, the resin being capable of adhering to said surface and to said grit, and a liquid propellant. The present invention also provides an aerosol means for producing a surface having an abrasive grit adhered thereto comprising an aerosol dispensing means and having contained therein the aforementioned aerosol composition.

Abstract: The present invention provides a device and method for propelling liquids to long distances. The invention is especially useful for marking animals such as sheep for identification purposes.

Abstract: An actuator for use with an aerosol container, the actuator having a passage therethrough which terminates in an orifice, the passage being configured such that the contents of the aerosol container may be communicated through the passage and discharged from the actuator at the orifice, comprising an actuator body, and one or more pairs of wings secured to the body, each wing having a bottom edge located proximate to the orifice and peripheral edges which are adjacent to and intersect the bottom edge, wherein at least a portion of the peripheral edge of at least one of the wings, from a point wherein said edge intersects the bottom edge of its respective wing, angles away from the body. There is further provided a base adapted for accepting such an aerosol container actuator.

Abstract: An apparatus and method for animating figures employs at least one collapsible, fluid chamber, and associated means for controlling the fluid pressure the chamber. In one embodiment, a single, inflatable chamber is employed, the chamber having a section of one wall which is less elastic than the remaining portion of the wall. In another embodiment, two collapsible, fluid chambers, and associated means for controlling the fluid pressure in each of said chambers are provided. The chambers are each helically wound in opposite directions and placed substantially parallel to one another.

Abstract: A water-based aerosol coating composition suitable for discharge from an aerosol container comprising: a monomer-modified alkyd resin which is rendered water-soluble by neutralization with a base, a rosin-modified maleic resin which is rendered water-soluble by neutralization with a base, a water-soluble organic solvent, water, and a propellant, preferably dimethyl ether. The composition provides a durable coating or film when applied onto a substrate. Further, the composition is non-flammable upon discharge.

Abstract: A two-part system and method for increasing the reflex-reflectivity of a substrate is disclosed wherein a first aerosol dispensing means containing a first coating composition capable of forming a base coating on a substrate and a second aerosol dispensing means containing a second coating composition capable of imparting reflex-reflectivity to the base coating is employed. The first coating composition comprises a binder resin and a solvent in which the binder resin is dissolved and the second coating composition contains transparent microspheres having a particle size from about 45 to about 90 microns and a carrier in which the transparent microspheres are dispersible. The substrate is coated first with the first coating composition via aerosol means to form a base coating which is subsequently coated with the second coating to impart reflex-reflectivity to the base coating.

Abstract: The present invention contemplates an aerosol composition adapted for providing a foam upon discharge from a suitable containment means, said composition comprising (a) a propellant, (b) water, (c) a water-insoluble polymer, (d) a surfactant, (e) a foam stabilizing agent, and (f) a solvent adapted for solvating said foam stabilizing agent, said foam remaining stable up to about ninety days if left undisturbed.

Abstract: A spraying apparatus is provided with a pair of discs for masking the material which is sprayed. The discs are mounted on an axle which is free to move up and down within the spraying apparatus as the spraying apparatus moves over the surface which is being sprayed. Each of the discs includes an axially extending flange which provides a well for retaining material which is sprayed onto the disc.

Abstract: A movable marking apparatus for marking a supporting surface includes a housing member, wheels rotatably mounted to the housing for engaging the supporting surface and rolling on it, and a handle assembly secured to a rear portion of the housing for controlling the apparatus and actuating the nozzle of a spray can. The apparatus also includes a counterweight element mounted on the front of the housing. This counterweight element prevents inadvertent lifting of the front of the apparatus and accordingly minimizes discontinuities and imperfections in the marks which the apparatus provides.

Abstract: A chassis assembly for a moveable spraying apparatus supports a container which contains material such as paint and a handle assembly for controlling the apparatus. This chassis includes a housing with a support beam which supports the handle assembly within the housing and at the side of it. It also includes a wind screen for shielding the discharged material from the wind, can holders for receiving spent and unused containers, and an indicator for maintaining the apparatus along a predetermined path.

Abstract: A movable marking apparatus for marking a supporting surface includes a housing member, wheels rotatably mounted to the housing for engaging the supporting surface and rolling on it, and a handle assembly for controlling the apparatus and actuating the nozzle of a spray can. The apparatus also includes a speed indicating assembly rotatably mounted on the apparatus and connected to a wheel of the apparatus. This assembly has at least one set of indicia disposed in spaced intervals on the assembly. This indicia appears as a solid line when a user moves the apparatus at a predetermined speed.
