    Abstract: A golf ball with improved distance is disclosed. The golf ball has a relatively low spin velocity coupled with a particular dimple number, diameter, depth and arrangement. The ball is characterized by a lower flight trajectory and longer total distance. The golf ball has 384 dimples .+-.3% and the dimples preferably have an average diameter of 0.145-0.155 inches and an average depth of 0.0103-0.0123 inches. The golf ball core can be either thread wound or solid. The cover can be transpolyisoprene or an ionomer.The materials of the core and cover are selected so that the golf ball has a spin velocity below 2900 rpm when hit at 230 feet per second by an implement having a face angle of 13.degree. with respect to the vertical. The dimples are substantially evenly spaced over the surface of the golf ball, and the dimple depth, diameter and number are interrelated according to the following formula:[554.3(d-x)-37(D-y].sup.2 +[138.6(D-y)+926(d-x)].sup.2=Swherein:d=average dimple depthD=average dimple diameterx=0.275-0.0041667Ny=0.2790-0.033NN=the exact number of dimples divided by 100 S.gtoreq.O.ltoreq.1.

    Abstract: An improved colored golf ball is disclosed. The golf ball is made with a fluorescent coloring. In order to improve durability and give very pleasing aesthetics, the fluorescent coloring is blended into the cover stock. The name and/or number preferably are stamped directly onto the core for surprisingly superior durability. The cover stock can suitably be a clear ionomer resin and for highest gloss a clear final coating can be applied. If the name or trademark is stamped directly onto the core, it is visible through the clear cover. A UV stabilizer may be included. If a dye is used, it is preferred that it be 0.01-0.4% by weight of the cover and if a pigment is used the preferred range is 0.5-6% by weight of the cover.

    Abstract: A radio antenna is made of conductive rubber. Uncured rubber is doped with conductive high structure carbon black in proportions greater than normally required to attain the desired volume resistivity. The doped rubber is milled at high shear until the standard deviation of volume resistivity is reduced below a predetermined value in the finished antennas. A copper-containing metallic stud is embedded in at least one end of the uncured antennas and is bonded to the rubber by vulcanization during curing of the rubber. The antenna has improved physical properties, uniformity of volume resistivity, and reduced resistivity variation with stress.
