Abstract: A method and apparatus are provided for fitting a condom-style catheter onto a penis of a user. The apparatus includes two jaws moveable toward and away from each other. The jaws, in a first position, surround a first portion of the catheter and retain against surfaces of the jaws a toroidal roll formed of a rolled-up open-ended sheath portion of the catheter adjoining the first portion. The jaws are then moved outwardly to a second position relative to each other so that an opening bounded by a wall of the first portion of said catheter between the jaws is shaped and opened up sufficiently to admit placement of an end of a penis therein. The jaws can then be moved inwardly to a position in which the catheter is located on the penis and the roll can be unrolled from the jaws and along said penis.

Abstract: A method and apparatus are provided for fitting a condom-style catheter to a penis of a user. The apparatus includes at least two jaw members movable towards and away from each other. The jaw members, in a first position relative to each other, surround a first portion of the catheter and retain against external surfaces of the jaws a toroidal roll formed of a rolled-up open-ended end sheath portion of the catheter adjoining the first portion. The jaw members are then moved outwardly to a second position relative to each other so that an opening bounded by a wall of the first portion of said catheter between the jaws is shaped and opened up sufficiently to admit placement of an end of a penis therein. The jaws can then be moved inwardly to a position in which the catheter is located on the penis and the toroidal roll can be unrolled from the jaws and thereafter along said penis by a user, so that the penis is located within the catheter.

Abstract: A separator for mixed solid particulate materials such as gold or heavy minerals which are dispersed in a host material such as sand. A circular disc has a slanting surface with a plurality of riffles for catching the heavy materials. The riffles are defined by a plurality of annular baffles each having short radial walls projecting toward the center of the disc. A water turbine having off-center weights is used to vibrate the disc.
