Abstract: A carpet cleaner for cleaning carpets includes a foam generation unit, roller brushes and a heated air drying mechanism. The foam generation unit uses multiple stages of foam generation for creating a very fine foam which is applied to the carpet. A suction device removes excess foam from the carpet after the brushes have gone over the carpet. Finally, heated air is blown across the carpet after the suction device has removed the excess foam. The carpet is cleaned, dried and ready for immediate use.

Abstract: Breaking equipment comprising a mounting bracket that is attached to an arm of a power shovel for vertical pivotal movement, a holder frame mounted on the mounting bracket for swivel movement, a hydraulic motor attached to the mounting bracket for rotatably and reversibly driving the holder frame or a swivel break mechanism which is used in place of the hydraulic motor for restricting swivel movement of the holder frame, a pair of pivot arms of a symmetrically L-shaped configuration attached at their mid points to the holder frame by means of pivot axes, the pivot axes being separated apart a predetermined distance H from one another so as to satisfy the equations; a=<b and H=<2h, wherein, a is a distance from the pivot point to the forward end of each of the pivot arms, b is a distances from the pivot point to the rearward end of each of the pivot arms, and h is a distance from the blade edge vertically to the line connecting the pivot point and the forward point of the application, a hydraulic cylinde
