Abstract: ABSTRACT OF THE DISCLOSURE      A valve operation control system for an internal combustion engine having an engine valve supported in an engine body for opening and closing.   A phase control means is interposed between a crankshaft and the valve operating cam shaft to control the rotating phase of the crankshaft relative tot the valve operating cam shaft.  A  valve drive means is interposed between the valve operating cam and the engine  valve to transmit the valve opening force by the valve operating cam to the engine valve.   The valve drive means includes a resilient valve opening means for generating resilient force in the valve opening direction and a holding means for holding the engine  valve in  a closed position while springs accumulate the valve opening force.          The holding means is selectively  operable to switch between a valve holding state and a valve  releasing state to control the valve opening timing of the engine valve in response to operating conditions of said engine.

Abstract: ABSTRACT OF THE DISCLOSURE     A cylindrical power brush for a vacuum cleaner includes two types of bristle tufts.  One type of bristle tuft is short and stiff for contacting and agitating a carpeted surface.  The other type of bristle tuft is longer and softer for contacting a hard surface.  In addition to the differences in length and bristle stiffness, the tufts for the hard surface contain substantially fewer bristles, whereby catching and rolling of carpet edges is avoided.  One embodiment alternates types of bristle tufts in a row of bristle tufts.  Another embodiment employs multiple rows of bristle tufts arranged such that a point on a surface being cleaned is contacted alternately by the two types of bristle tuft. Winding up of thread and hair on the axle of the rotating brush is avoided by overlapping annular extensions on a support wheel and a brush spindle. The brush support wheel is locked in place in the floor tool by resilient locking tab integrally formed with one of the halves of the floor tool.

Abstract: A pallet has at least one board secured to a plurality of like elongated parallel stiffening ribs having flat upper sides secured to the board and lower sides formed with downwardly projecting and longitudinally spaced bumps. These ribs are each formed by filling into an upwardly open elongated mold of generally regular cross section a mass of coarse and fine particles and a binder in such a manner that the fine particles are concentrated in the lower portion of the mass and the coarse particles are concentrated in the upper portion of the mass. The mass is then compressed downwardly in the mold to a relatively great extent at several longitudinally spaced-apart locations and to a lesser extent therebetween to form upwardly projecting bumps or feet between these locations. The thus compressed mass is cured into a stiffening rib which is inverted and has the board secured to its planar upper surface opposite its feet.
