Abstract: In order to perform scrub cleaning of a substrate, two different scrub heads 31 and 32 are employed. The scrub head 31 is superior to the scrub head 32 in terms of a capability of removing contamination. The scrub head 32 has a low level of adhesion to the contamination as compared with the scrub head 31. The scrub heads 31 and 32 are moved such that the scrub head 32 follows the scrub head 31. Consequently, it is possible to clean the substrate without re-applying contamination, which has been once removed from a surface of the substrate, to the surface of the substrate again.

Abstract: A machine for automatically applying lane dressing travels up and down the lane to apply dressing according to a certain predetermined and preselected pattern. A single dispensing head travels back and forth across the lane as the machine moves linearly along the lane so that dressing is transferred to a buffer brush that engages the lane surface and applies the dressing thereto. The oil pattern is determined by actuation and deactuation of the dispensing head as it traverses the lane, such control of the head being provided by a special pattern control device in the nature of a cylindrical pattern tube that extends alongside the path of travel of the dispensing head. A sensor on the dispensing head detects pattern structure on the control device to responsively actuate and deactuate the head. In a preferred form, such structure takes the form of a series of metallic strips extending parallel to the path of travel of the dispensing head and spaced circumferentially around the periphery of the pattern tube.

Abstract: The apparatus includes a water tight vehicular body of a low profile. A user controls the vehicle from a forward cockpit. The cleaning apparatus further includes both forward and rearward booms. The forward boom has a slurry trap interconnected to its forward extent. Additionally, a brush is secured to the rearward boom. Both the booms can be elevated and lowered to selectively bring the trap and brush into contact with the ground.
