Abstract: Glass bodies are decoratively affected by having coatings of dichroic materials applied to an uneven surface, which in turn are coated with an opaque coating that may be protective, absorptive, or reflective. This combination of coatings transmits or reflects different colors of light in patterns that are determined by the unevenness of the coated surface, the design of the dichroic film, the design of the opaque coating, and an angle of view of an observer. Both the color patterns and the colors forming the patterns change with different viewing angles of the coated surface.

Abstract: An illuminated ring including a pair of light emitting diodes with an associated switch. Such switch allows the selective actuation of either diode. Also included is a cap with opaque indicia printed thereon for releasably coupling about the diodes in use.

Abstract: A collapsible structure comprises a separating structure of poor wet strength sandwiched between two sheets of material, at least one of which is of such a nature as to allow the passage of moisture. The invention also includes a method of building using such a structure.

Abstract: An agricultural spraying assembly including a plurality of nozzles divided into groups with each group being supplied liquid through a solenoid valve with a motorized proportioning valve being adjustable to control the pressure supplied to the solenoid valves and, in turn, to the plurality of nozzles. The assembly includes a main control box which is normally situated on a spraying trailer and a remote control box which is normally situated on the pulling tractor and is supplied power from the tractor's battery. Each of the control boxes includes switches for each of the solenoid valves as well as a pressure adjusting switch for adjusting the pressure supplied to the nozzles. Each control box has a pressure gauge for indicating the operating pressure supplied to the nozzles.
