Abstract: A hemorrhoid message device has a shaft with a first end section, a middle section and a narrow section. The middle section is positioned between the first end section and the narrow section. The narrow section has a concavity extending around the diameter of the shaft. The narrow section has a first end separated from a second end by between one-half inch and three-quarters inch diameters of the first end and the second end of the narrow section are equal. The shaft has a length between one and a half inches and four inches. The middle section can be of straight cylindrical, concave or convex shape.

Abstract: An apparatus for massaging hemorrhoids through the contraction of a human sphincter including a head having a size suitable for fitting into a human rectum and through the sphincter and a resistor connected to an end of the head.

Abstract: An apparatus for releasing congested prostate fluid including a head having a size suitable for fitting into a human rectum and through a sphincter and having a surface for pushing on a prostate gland, a rod connected to a bottom of the head and extending outwardly therefrom so as to guide a movement of the head as the sphincter relaxes and contracts, and an abutment member positioned on the rod opposite the head so as to push on the perineum area simultaneously with the head pushing on the prostate gland. The abutment means has a variable angular relationship with the head. The angular relationship is greater upon entry into the rectum and less upon pushing on the perineum and the prostate.

Abstract: An apparatus for releasing congested prostate fluid including a head having a size suitable for fitting in a human rectum and through a sphincter and having a surface suitable for rubbing a prostate gland, and a rod connected to a bottom of the head and extending outwardly therefrom. The rod serves to position the head and guide a movement of the head as the sphincter contracts and relaxes. An abutment surface is affixed to the rod distal the head. The abutment surface serves to contact a perineum area and to push up on the perineum area as the sphincter contracts. The rod is a rigid rod having a generally L-shaped or C-shaped configuration with a radius of curvature such that the head tilts toward the prostate gland as the sphincter contracts and draws the head upwardly. The head has a generally ellipsoidal shape. The head is formed of rubber-like material.

Abstract: Two stroke cycle internal combustion engine comprising; a ported cylinder, a cylinder head with an opening, a piston with an opening, a ported sleeve which is axially displaced inside the cylinder, extending through the cylinder head opening and the piston opening to form an annular combustion chamber. The position of the port in the sleeve is adjustable, longitudinally and latitudinally to control port timing, duration and the direction of the gasses flow inside the combustion chamber.

Abstract: A lengthwise scavenging system for a two stroke internal combustion engine comprising a ported cylinder, a piston, a wave formed sleeve which is attached to the piston, and a reentrant cylinder head which provide annular recess for the sleeve.
