Abstract: A testicular volume measuring device has a container, a lid, a sealing ring, and a plurality of indicia. The lid is removably attached atop the container, and the plurality of indicia is positioned on a lateral wall of the container, which is constructed of a transparent material and delineates an internal cavity. The lid has multiple lid members, which are removably attached to each other. The lid members have cutouts which form a central aperture on the lid, within which the sealing ring is secured during use. One or more testicles may be placed through the sealing ring, around which the lid members are affixed, and the lid is attached atop the container. Fluid volume measurements using the indicia before and after placement of the testicles into a quantity of fluid contained within the cavity enable measurement of the volume of the testicles through fluid displacement.

Abstract: An extendable buoyant board with pairs of telescoping sections which are secured in an extended relation to one another by internal pressure from an inflatable pneumatic bladder enclosed within the sections. By retaining each of the inboard ends of successively smaller pairs of extension sections within the adjacent next larger section, the multisection board, when extended, provides substantial rigidity and strength. The telescoping arrangement is preferably provided by a central tubular section with an opening at each end, and an internal cross-sectional area which diminishes from the center to each opening. A first pair of opposed telescoping tubular extension sections is slidably and non-removably engaged within the outboard end of the interior of the central section.

Abstract: A step nose is formed having a tread portion and a riser portion, formed initially as a flat strip, the tread portion having a receiving slot formed therein, and the riser portion having a hook formed as part thereof. The tread and riser portions are stretchable with respect to one another so as to enable the hook to interlockingly engage the slot when the tread and riser portions of the flat strip are bent towards one another to thereby form a step nose ready for installation. Machines are further disclosed for forming the flat step nose strip into an assembled state by bending the tread and riser portions and interlocking them together.
