Abstract: This invention relates to a racket string comb, to be used on the strings in the head of a tennis, racquetball, squash or badminton racket, that can be manually manipulated to move the strings back to their correct position. The improved tennis racket string straightener is a one-piece pocket comb, preferably of molded plastic, which consists of a comb body and integrally placed, widely spaced, narrow claws depending therefrom, along the width thereof. The claws in the preferred embodiment are all of the same size and spacing. The comb body has a handle extended from the comb body at a generally fortyfive degree angle, rounded at the bottom to provide finger comfort and prevent pocket snagging.

Abstract: A card game which comprises a set of cards of the same size and geometrical configuration, each having a square playing surface. Each of the four sides of each card has a selected visible indicia. The criteria determining how the indicia are to be arranged on the sides of the cards are mathematically selected so as to permit the use of the game as a mathematical puzzle that may be played by one player, played competitively by two players, or for other purposes of entertainment or intellectual stimulation. In many of the games the cards or other playing pieces are arranged in a mutually abutting side-by-side relationship whereby the indicia on each of the sides may match and align with the indicia on respective abutting sides of other cards of the set, and with the top surfaces of the abutting cards forming a square.

Abstract: A microphone stand assembly incorporating an adjustable height and angle microphone support column to be securely oriented in a plurality of positions is provided. In the preferred embodiment the column accommodates six microphones. This arrangement permits performers to utilize a single microphone stand with six microphones at different heights for simultaneous voice and musical instrument amplification. In addition, the invention provides a means for adjustably retaining a set of microphones in a preselected position, usable in a horizontal position, vertical position or in any other angle, allowing for a change in the position of a microphone support column and for accommodation of more than one microphone housing slot mounted on a single microphone support stand assembly. The result is an apparatus, relatively inexpensive and compact, with possibility of use by people of different heights without adjusting the stand or the microphone.
