Abstract: System for automatic control of chlorine content and pH in swimming pools. This system includes an electrolytic cell for generation of chlorine and caustic soda as needed, and an acid supply system for adding hydrochloric acid to the pool as required. Generation of chlorine and addition of acid are controlled automatically in response to sensed oxidation-reduction potential (ORP) and pH of the swimming pool water. The sensors for this purpose may be placed in a conventional pool recirculation line, and chlorine, caustic soda (which is co-produced with chlorine) and hydrochloric acid may be added to the pool via the recirculation line.The electrolytic cell has a porous separator dividing the cell into anolyte and catholyte compartments. The latter is operated at a slightly higher pressure than the former. Chlorine generated in the cell is separated from spent brine, which is recirculated back to a brine tank where it is resaturated. The system may include a timer.

Abstract: A double-acting, vending machine dispensing mechanism is shown whereby product units are alternately dispensed from adjacent storage compartments by an ejection device. The ejection device comprises a horizontally reciprocating dispensing bar connected to, and moved by the pendular movement of a rocker frame, motion of the latter being induced by the camming action of a gear mounted boss. The camming gear, in turn, is driven by a separate gear attached to the operating handle of a coin released mechanism.

Abstract: A seal for a bottle and cap assembly. The seal is formed from a heat shrink sheet which is adhesively coated on one side. A pull tab is formed by a pair of cuts in one edge of the sheet forming the seal and a tear strip is adhesively secured to the back of the sheet in registration with the pull tab. After being adhesively secured to a bottle and cap assembly, the sheet is heat shrunk to conform to the contour of the bottle and to provide a flange over the bottle cap. In one embodiment the pull tab is in registration with the area of joinder between the cap and the bottle and in another, the sheet is devoid of adhesive in an area extending from the pull tab and bridging the joinder between the cap and bottle. In either case, pulling of the pull tab separates the sheet into a first piece adhered to the cap and a second piece adhered to the bottle allowing for the only possible access to the bottle without evidence of tampering showing in the sheet.

Abstract: A roofing fastener is shown adapted to fasten membrane roofing film to roofing structures. The fastener comprises a base plate having a segmented upper, tapered circular flange section; a segmented middle circular ring locking section; and a lower base section. After attaching the base plate to the roofing structure by means of a fastener inserted through an axial hole located in the center of the base plate, and an annular snap ring having an internal diameter just large enough to fit over the film covered base plate when the segments of the base plate are compressed, is forced over the film covered base plate, and adjacent to the locking section, thereby locking the roofing film in place.

Abstract: A carpet laying tool is disclosed comprising an angular member connected at one end to a carpet wedging, rotatable circular wheel, and at the other end to a carpet compressing, swivelable block member. The tool is used to wedge the carpeting being laid into the juncture of walls and floors, while simultaneously pressing it onto carpeting tack strips or an adhesive, whichever is being used to retain the carpet in place. The tool is used by holding it by the angular member and placing it horizontally on the carpeting, adjacent and at a slight angle to a wall, so that the wheel and block are both in contact with the carpeting. A downward force is then applied in the direction of the angle of tool disposition, and the tool is moved along the juncture in the direction of the wheel, simultaneously forcing the carpeting into the area of the juncture, and onto the tack strip or adhesive.
