Abstract: A hydraulic actuator comprises a first piston mounted within a primary bore and moved in response to a low pressure force while a second piston is mounted in an axially aligned secondary bore and is moved in response to a high pressure force. The second piston engages the axially aligned first piston and both are moved under the influence of the high pressure while the first piston only is moved by the influence of the low pressure force. The piston areas are in proportion to each other as the separate pressure forces so as to provide a substantially equal output actuating force irrespective of the actuating pressure.

Abstract: A pill container and permanently attached cap form a three-sided prism-shaped safety bottle. The container is provided with a top to which the cap is secured permanently by a large-headed shaft from the cap protruding into the container top through an elongated slot with a detent at each end. A slot in one side of the cap rides on a track protruding from the top of the container. An indented section of the cap fits within a dispenser opening on top of the track. Pushing from one side causes the cap to move laterally along a straight portion of the track while the shaft is forced through the tight slot from the first detent to the second. The cap is then pivoted around the shaft, guided by a curved portion of track. A protrusion on the track stops the cap rotation when the opening is exposed to dispense the pills one at a time therethrough. Strength but not manual dexterity is required for the two discrete opening steps.

Abstract: A freight container includes a cylindrical tank disposed within an outer frame. The tank is connected to the corner regions of the frame by means of eight saddle pieces which have curved borders welded to tensioning rings surrounding the tank near the ends thereof. Each tensioning ring is composed in the peripheral direction of the tank of two sections clamped together by tensioning screws and locked in both axial directions of the tank by a plurality of sheet metal pieces welded to the tank shell on both sides of each tensioning ring. The tank may be detached from the frame by loosening the tensioning screws whereupon the tensioning rings may be raised over the sheet metal pieces in axially moving the frame relatively to the tank. In assembling the freight container, the metal pieces are welded to the tank in the final manufacturing step after the tank and the frame have been positioned relatively to each other with the required dimensional accuracy.

The rim is configured such that when the can body is subjected to elevated internal pressures, the rim deforms in a controlled manner, and this deformation causes the domed wall to move axially away from the opposite end of the can body without buckling, thereby increasing the volume of the can body.

Abstract: A drum apparatus includes an injection-molded or extruded rim member formed into a ring shape and permanently attached to a blow-molded thermoplastic drum body around the top portion of the drum adjacent to the sidewall section of the drum body. The rim member includes an inwardly, radially projecting annular protuberance which is juxtaposed adjacent an annular groove in the drum just below the top of the drum. The rim member is attached to the drum while the rim member is at an elevated temperature by positioning the rim around the drum. As the temperature of the rim member decreases, the diameter of the rim member decreases causing the annular protuberance to seat into the drum's annular groove. The rim member also has a grasping beak which provides an outwardly extending support lip, a top edge providing a stacking ridge which is positioned vertically over the sidewall of the drum, and an annular seizing surface facing radially inwardly. A short chain hoist groove is formed in the bottom of the drum.

The card is also used to imprint the card number embossed thereon on coupons in a coupon book then handed to the shopper with the card then returned to the dispenser to enable the sequential dispersing of another card. A card being reinserted into the card dispensing carousel is inserted into a card return slot to rest at one end on a retainer upper ledge until an operator depresses an actuator button forcing the end edge of the returned card past the upper edge of the retainer down onto a lower ledge of the retainer activating a carousel upper drive switch in the process.

Abstract: A self-cleaning valve used at the outlet of a container has an elongated flexible flattenable outlet tube with an inlet for receiving material to be dispensed from the container, and an outlet for dispensing the material. In the at-rest condition of the valve, a pair of spring-biased rollers contact the opposite sides of the tube at a location spaced from the outlet end and hold the tube in a closed condition. When material is forced through the inlet end of the tube it pushes the rollers toward the outlet against the spring biasing action. At the outlet end the rollers separate and permit the tube to open so that the material can be dispensed. After the material has been dispensed, the springs return the rollers to the at-rest position and the rollers effect a self-cleaning action on the tube.
