Abstract: A shelf box is designed for use with a shelf rack or storage cabinet open on both sides so that the shelf box can be removed from either side of the rack or cabinet. Two stop members are respectively mounted adjacent to opposite ends of the shelf box for pivotal movement between stop and release positions, and are interconnected by a pivoting linkage so that when one stop member is in its stop position the other stop member is in its release position. The stop members are disposed so that in their stop positions they are engageable with retaining portions of the overlying shelf. Thus, when one end of the shelf box is withdrawn from the rack or cabinet it will be stopped by engagement of the adjacent shelf retaining portion with the stop member at the opposite end of the shelf box in its stop position to prevent inadvertent complete removal of the shelf box.

Abstract: A liquid soap dispensing system includes a closed soap container having a manually actuated dispensing pump carried therebeneath. Refill of the container is by a plastic refill squeeze bottle with a neck defining an outlet opening closed by a membrane recessed therein. One embodiment of the bottle is formed by ultrasonically welding in the neck end, after the bottle is filled, a plug defining a cylindrical sleeve closed at the inner end thereof by a closure wall. The neck is inserted into a well in the top of the container, and a hollow piercing member at the bottom of the well ruptures the membrane or closure member, whereupon soap may be squeezed from the bottle and through the passage through the hollow piercing member, which is constricted by septa dividing the passage into channels such that flow of liquid soap therethrough at equal pressures at both ends of the passage is substantially inhibited.

Abstract: This invention relates to a scrubber for removing or neutralizing pollutants from air or other gaseous media by means of water and/or suitable chemicals. The construction embodying the invention is simple, compact and susceptible to prefabrication and provides means to confine or restrict the flow of polluted material through random paths. The polluted air is forced into a jet or jets of scrubbing fluid, such as water or a chemical, then along a plurality of separated paths within which are located movable flexible scrubber belts and small spheres of plastic or other materials, preferably hollow and light. There is also provided for some cyclone action prior to discharge from the scrubber. The nature of the scrubber is such as to permit the use of metal or plastics and can be made in different sizes and shapes. An additional group of hollow plastic spheres may be provided for condensing scrubout liquid or vapors from scrubbed gaseous material after the scrubbing operation.

Abstract: A connector for tubes of square cross-section comprises an elongated hollow metallic member of such size and shape in external cross-section as to be insertable within an end length of a tube for connection therewith. The member has at least two external longitudinal surfaces of minor width on opposite sides thereof. Spaced integral transverse teeth are provided on at least one of the longitudinal surfaces, the transverse distance between the surface of the teeth and the opposite longitudinal surface being greater than an internal transverse dimension of a tube to be connected to the member. Relative rotation between a tube and a member inserted therein causes the teeth to bite into an internal surface of the tube and thus establish secure connection. The connector may have teeth on both opposite longitudinal surfaces of minor width, and there may be a second pair of toothed longitudinal surfaces of minor width in quadrature relation with the first pair.
