Abstract: An apparatus adapted for mounting adjacent the front pressure roller of a vehicle which applys plastic tape to pavement particularly to form highway marking patterns, with a horizontal plate having a slot through which plastic tape is advanced, a plurality of rollers driven by the pressure roller and engaging end advancing tape through the slot when a piston is actuated to move idler rollers to cause engagement of tape and rollers, a piston operated cutter beneath the plate and adjacent the slot and a guide chute for guiding the tape beneath the front roller.

Abstract: An automatic volume control system for controlling the rate at which fluid, such as paint, is sprayed from spray guns on a mobile vehicle as a function of vehicle speed. The device permits paint lines to be maintained at a uniform thickness independently of the vehicle speed. A tachometer generator generates a voltage proportional to the vehicle road speed which voltage controls the opening of an adjustable hydraulic valve. Hydraulic fluid passing through the hydraulic valve drives a hydraulic generator which in turn drives a spray gun system. The voltage from the tachometer generator thereby causes the hydraulic fluid to drive the hydraulic motor and paint pump at a rate which is proportional to the vehicle road speed. The hydraulic fluid is suitably pumped through the hydraulic valve to the hydraulic motor by a hydraulic pump driven by the power take-off of the vehicle.

Abstract: The apparatus provides an internal means for spraying and heating quick drying traffic paint to a minimum temperature of 120.degree. F. utilizing a primary heat collector within which engine liquid is in thermal communication with engine exhaust gases and heated compressed air. Such heated engine liquid is then used as a heat transfer medium to elevate the temperature of quick drying traffic paint within a shell and tube heat exchanger.

Abstract: Ambient drying traffic paint compositions and methods for their application are disclosed comprising a resin binder and pigment(s) in a three-component or four-component solvent system, in parts by weight of:Solvent boiling point: 190-141.degree. F.; 5-11solvent boiling point: 140-106.degree. F.; 12-17solvent boiling point: 105-90.degree. F.; 2-28solvent boiling point greater than 225.degree. F; 0-12The disclosed compositions are applied at ambient temperatures without the use of external heating means and a relatively fast dry time of about 20 to 60 seconds is obtained.
