Abstract: A powder dispensing device for dispensing powder in controlled quantities used in connection with playing billiards is disclosed. The device of the present invention includes a box-type enclosure made of wood or plastic or other suitable material, into which a loose weave cloth container containing powder such as talcum powder is attached to the bottom surface of a substantially semi-circular mounting platform inside the enclosure, closely adjacent to and above an opening in the front of the enclosure. Mounting flanges formed by extending the back of the enclosure beyond the length of the sides of the enclosure allow the entire device to be mounted to a wall or other substantially vertical surface. When the cloth container is agitated, the powder is dispensed directly onto the fingers of a player.

Abstract: A safety device for a stairway or other inclined surface includes a rail and a safety belt. The safety belt is wrapped around the rail to form a noose. The noose allows the safety belt to move freely along the rail when a person is not falling and prevents the safety belt from moving along the rail when a person is falling.

Abstract: A reusable printing sleeve for supporting flexible printing plates, the sleeve having a limited circumferential resilience, whereby when subjected to air jets emitted from the apertures in the wall of a printing cylinder, the sleeve is dilated to facilitate the application of the sleeve to the cylinder or its removal therefrom. The sleeve is constituted by four or five interlaminated layers. The innermost one or two layers are comprised of wide strips of plastic film helically wound about a cylindrical shape. The outer three layers of the sleeve are constituted of three interlaminated layers each formed by helically wound of synthetic plastic tape. All three outer layers are wound at helix angles substantially different from the innermost layer or layers.

Abstract: An improved ladder stabilizing device for supporting a ladder a spaced distance away from a substantially vertical surface is disclosed. The device of the present invention includes a U-shaped support bar which forms two parallel legs, the ends of which rest against the substantially vertical surface. The support bar is attached to a leveling device consisting essentially of a U-shaped channel. The ends of the leveling device rest against the side rails of the ladder and the support bar engages the U-shaped channel. The leveling device and the support bar are simultaneously attached to the side rails of the ladder. The stabilizing device is easily removable and holds the ladder a distance from the substantially vertical surface to provide a safe angle of support.
