Abstract: ABSTRACT OF THE DISCLOSURE            In order to permit a steering wheel to be simply connected  to a  steering  shaft  having  a  frusto  conical tapered  portion,  a  serrated  or  splined  portion  and  a threaded portion, in a manner which permits ready adjustment of the wheels'  position with respect to the shaft,  the central boss of the steering wheel is divided into separate upper and lower boss members.  The lower boss member seats on the tapered portion and is rigidly connected with the steering wheel.  The upper boss member fits on the serrated portion  so  that  relative  rotation  is  prevented.    By tightening a nut on the threaded portion of the steering shaft, force can be applied through the upper boss member to the  lower one in a manner which produces a  frictional engagement between the lower boss member and the tapered portion  which  prevents  relative  rotation.     Various mechanical arrangements are provided between the upper and lower boss members to either limit the amount of relative rotation which can occur therebetween prior the tightening of the nut or control the relative rotation to the degree that accidental relative rotation which is not deliberately induced cannot take place, even in the absence of the nut applying  sufficient  force  to  prevent  relative  rotation between the shaft and the lower boss member.

Abstract: In an internal combustion engine comprising a valve operating system connected to a pair of intake valves and arranged to open one of the intake valves only in a very small amount such that the one intake valve is brought into its substantially inoperative state, in a suction stroke mainly in a low speed rotation region of the engine, a fuel injection valve capable of injecting fuel toward a pair of intake ports independently corresponding to the intake valves, and a control means for controlling the operation of the fuel injection valve, the control means is arranged to control the fuel injection valve with a fuel injection completion time determined within a suction stroke, when one of the intake valves is substantially inoperative state. This ensures that when one of the intake valves has been brought into its substantially inoperative state, the injection of fuel by the fuel injection valve can be completed when in the suction stroke. so that the injected fuel can been sequentially introduced into a combustion chamber in a condition of the other intake valve being open, thereby achieving an axially stratified air charge to provide an improved combustibility.

Abstract: A granular material which includes an inorganic substrate and a ceramic coating shows improved adhesion to bituminous surfaces, decreased alkalinity, and, when formulated as a three coated algae-resistant granule, exhibits improved algae-resistance over previously known granules. The ceramic coating comprises the reaction product of an alkali metal silicate and an aluminosilicate, the ceramic coating further including a borate compound and zinc oxide having a particle size less than 0.13 micrometer. It has been found that the use of a borate compound and zinc oxide having the stated particle size allows the granules to be adhered to a substrate for longer periods of time, thus producing a surface which retains its original color for a longer period of time. Methods of producing such ceramic-coated granular materials, and composite sheets including the granules are also presented.
