Abstract: A novel card game set including a plurality of card game block-style tiles. Each tile bears traditional Western-style card indicia. Each tile is made of a plurality of individually laminated wood layers permanently prressed together to form a high gade plywood piece. Each tile is completely covered with a protective waterproof enamel coating. The waterproof enamel coating has a granular substance to give each tile a semi-rough exterior surface to facilitate gripping. The tiles are of sufficient thickness for convenient handling by young, unskilled and arthritic persons. Each tile is of sufficient weight to resist the force of wind and sudden drafts for facilitating the playing of games outdoors. The card game set also including a rack for supporting the tiles in strategic alignment.

Abstract: The invention is an improved stethoscope head having a conical shell-like head for improved acoustic detection and transmission. In its preferred embodiment, a stethoscope head may be constructed from a sea shell having a relatively broad, generally circular aperture defining a sound chamber opening, said chamber having a naturally polished, sound reflecting, interior surface. The interior surface defines a conical acoustic chamber having a generally helical axis resulting in a deep, yet compact chamber which increases the effective sound power radiated along the axis as acoustic waves propagate thereby functioning as an acoustic transformer and enhancing the fidelity of the received signal while masking unwanted sounds produced by the anatomy.
