  • Publication number: 20200338578
    Abstract: Pneumatic spray guns (10) for applying sprayable materials (M) to various surfaces are disclosed. During use of the pneumatic spray guns (10), a tube (T) of flowable texture material (M) to be sprayed is loaded into a pressure canister (12) of the spray gun (10). Pressurized air is fed to the tube (T) of material (M) to be sprayed and is also fed to a spray nozzle region of the gun (10) to contact the material (M) after it has exited the tube (T) in order to provide a desired spray pattern (S). The pressure applied to the pressure canister (12) and/or the pressure applied to the spray nozzle (20) may be varied in order to control the spray pattern (S).

  • Publication number: 20190225310
    Abstract: An arrangement of fenders nested together for compact storage, the fenders including two or more cylindrical bodies having a cavity accessed through the fender top, the fenders being similar shape but graduated in size such that the cavity of a larger fender tensionally receives the next smaller sized fender, the outer diameter of the smaller fender equal to the inner diameter of the larger fender cavity. A fender has a rigid inner core surrounded by a compressible shell made of foam or similar material. The inner core has attachment points for a rope or line. The smallest nesting fender in the set has a cavity diameter sized to fit a commercially-available, off-the-shelf fender. The fenders may be separated and deployed at individual locations on a vessel, or kept together and deployed as a single fender capable of absorbing a greater impact than any of the fenders individually would absorb.
