  • Patent number: 4088361
    Abstract: Pockets, defined by molded plastic shells, are embedded in a massive concrete article. Lifting cables have rods to fit into the pockets. The shells which define these pockets are injection-molded to provide a lateral spline to pass a key formed on the lifting rod, and also have a parti-cylindrical end housing, closed by a snap-fitted cover plate, within which housing the key rotates to lock the rod in the socket when lift is applied to the rod.

  • Patent number: PP4195
    Abstract: A new and very productive variety of flowering-fruiting peach tree, bearing an abundance of ornamental double flowers of strong reddish pink color in the last weeks of winter in Southern California, followed by a heavy crop of fairly large freestone fruits, which ripen on and after mid-July. The aroma and flavor of the fruit are strong, and the flesh is fine and tender, with melting texture and orange-yellow color. The growth habit of the tree is moderately vigorous, and its chilling requirement is slightly less than "Springtime".

The color changes from reddish orange to yellowish pink as the flower matures.
