Abstract: A method of packaging liquid detergent or fabric softener for single load use comprising thermoforming a container from a thermoplastic material such as polypropylene, polyethylene, polystyrene and the like, to a size sufficient to contain a 3-4 ounce amount of liquid detergent in a well thereof. The container comprises an open well with a peripheral lip an open end thereof. A printed foil strip, sized to cover the opening and at least a full circumferential portion of the container lip is heat sealed to the thermoplastic after the detergent is disposed therein. The foil and heat seal are of sufficient strength to retain the 3-4 ounces of liquid detergent even in an obverted position with jostling such as drug transport. Because of the heat seal, the container is not reclosable and storable and the full contents must be used once the container is opened, i.e., for a single use.
Abstract: A dispenser is formed of a flexible plastic pouch which has a removable flap providing an opening adjacent the bottom of the pouch, and a transversely disposed thermoplastic band adjacent the flap opening for reinforcing the pouch at the opening. A plurality of stacked reclosable ended, opened, separate plastic bags are disposed in a folded stack within the pouch. The folded plastic bags abut the reinforcing band adjacent the bottom of the pouch. A portion of one outermost plastic bag reclosable end is disposed in the pouch opening, so that the user by the thumb and then the forefinger pulls the one plastic bag end portion causing the one plastic bag to slide over the adjacent plastic bag and through the opening without tearing the pouch. After removal of the one bag, the next adjacent bag is then similarly positioned for removal. The removed plastic bag is immediately ready for filling. The dispenser of the present invention avoids undue manipulation to remove and eliminates the need to open the bag.

Abstract: A gate latch has a handle with a cojoined adjustably sized elongated rigid metal rod, which rod is rotatably disposed in sleeves frictionally retained within a drilled hole in a fixed post of a fence. The rod is formed with a plurality of spaced parallel threaded through holes. The handle has a transverse hole and is mounted to the rod by a bolt passing through the handle hole and one of the rod holes disposed at the end of the rod on the outside of the post. The rod is operably connected to a spring return locking plate for locking a gate rod which gate rod is fixedly mounted to an openable gate. The user first drills the post hole to receive the elongated rod slidably disposed in the sleeves, and then cuts the elongated rod to a length to accommodate the thickness of the post, and then attaches the handle at the hole adjacent the cut end of the elongated rod. The user in operating the gate latch rotates the handle downwardly which in turn rotates the elongated rod in the post hole.
Abstract: A horizontal connector interconnects adjacent ISO shipping containers. The connector has oppositely disposed locking arms which engage the inside surfaces of the respective container corner fittings. A push block assembly moves in a first direction to rotate the locking arm to engage the inside surface of a corner fitting, and then a reactive force from the surface engagement causes the push block to move in a second direction angularly disposed to the first direction to in turn cause push block surfaces to be frictionally engaged to lock the arm to the corner fitting. This locking action permits the containers to remain securely interconnected even when the connector and containers are subjected to excessive vibrations.

Abstract: An injection blow molding machine construction utilizes pairs of C-shaped cut plate members to support clamps for the injection mold and for the blow mold, respectively. The injection molding frame members are angularly disposed at 60 degrees with respect to the blow molding frame members. The frame members are co-mounted at the ends of the C-shaped members to a pre-stressed central vertically disposed column or post. The respective injection mold and blow mold clamp forces are transmitted to the respective frame members and in turn to the column in a balanced manner to avoid flexure of the plate members. The present construction reduces the bulk of conventional injection blow molding machines, eliminates weldments and provides for ready assembly of the machine and ready access to the molds so as to reduce downtime.

Abstract: A pair of parallel safety bars are track-mounted above the stairs of a stairway. The safety bars are formed so as to be gripped by the user in ascending or descending the stairs. The user steps between the bars, with each bar being hinged to permit such access, and grabs the bar in the direction of ascent or descent. The track-mounted end of the bar is pivotally connected to a shoe which slides in the track as the person moves on the bar downwardly on the bar or the weight of the user pulls the bar downwardly, friction braking elements on the shoe and in the track are contactingly engaged to restrict further movement of the bar thereby preventing the user from falling down the stairs.
Abstract: An injection molding machine has a high volume cylinder with a piston slidably disposed in the cylinder. The piston is formed with channels and check valves for selective communication from the back of the cylinder to the front of the cylinder. A vertically disposed screw plasticizer provides molten thermoplastic material to the back of the cylinder, which material flows to the front of the cylinder with rearward movement of the piston. When the front of the cylinder is filled with thermoplastic material, the piston is moved forewardly to inject the thermoplastic material into a mold. A reciprocating screw plasticizer first assists in filling the front of the cylinder, and then in completing the injection molding under a high pressure. Novel composite thermoplastic products may be produced.
Abstract: A vessel is provided with a flexible plastic tube containing an electrical contact switch. Impure water is added to the vessel between the tube and the wall of the vessel. The vessel is then placed in a home freezer. Upon partial freezing of the impure water, the ice expands to flex or compress the tube to close the switch so as to actuate a detector or alarm. The user then removes the unfrozen water, and allows a fraction of the ice to melt. The just formed water is checked for purity by a conductivity measurement. If impure, the water is removed, and the ice is allowed to further melt until the desired purity level is reached at which time the remaining ice is melted to obtain purified water. The device and method are particularly suitable for home use to economically obtain purified water.
