Abstract: A shock absorber for water-skiing 59 provides multiple adjustments to the adjacent cores 14 of the duplex core 15, and a weave assembly 29 securing a multipurpose assembly 48 in the cavity thereof, and provides attachment means 40,45 for use between the boat and the tow line assembly. In addition, the pneumatic duplex core 15 provides emergency floatation properties.

Abstract: A shock absorber for waterskiing 59 provides multiple adjustments to the adjacent cores 14B, 14S of the dihedral core 15 and the weave assembly 29 securing the multipurpose assembly 48 in the cavity thereof, and provides attachment means 40,45 for use between the boat and the mainline. In addition, the pneumatic core 14 provides emergency floatation properties.

Abstract: A type of tape which embodies two faces each containing a pressure sensitive adhesive coating. One face has a coating with a lesser degree of adhesive capability than the coating on the opposite face. The latter can be placed on a first material to form a pattern thereon, thus leaving the face with the coating having the greater degree of adhesive capability exposed. An object having a meeting surface may then be applied to the exposed coating. When that object is removed from the first material, the tape pattern is transposed to the backside of said object. This eliminates the necessity of using measuring tools and conventional methods to find and transpose the pattern from the first material to said object.

Abstract: A single copy newspaper vending machine which dispenses one newspaper copy each time proper coins are deposited. Newspapers are stacked on a tray which is urged upwardly toward a ski device that rides on the newspaper stack. The ski device can be pulled forwardly to dispense a single newspaper by depositing proper coins and pulling on the handle of a slide arm. The slide arm is normally locked in a retracted position but is released when the coins are accepted. The ski device includes pointed prongs which penetrate the upper surface of the top newspaper in the stack. The back folded edge of the top newspaper is engaged by cleats projecting from a cleat plate carried on the ski device. A pivotal dog member assures that the slide arm is moved through a single complete stroke each time it is released. After the stack of newspapers on the tray has been exhausted, the next stroke of the slide arm causes the dispensing of a display copy carried in a display case on the front of the machine.
