Abstract: Apparatus is disclosed for injection molding a partitioned container having four sidewalls, an open top and a closed bottom. Thermoplastic material from a primary sprue flows through a runner system to inlet gates disposed to open into the mold cavity in a generally common plane lying at about the open top of the container to be molded and along opposed container sidewalls intermediate adjacent partition walls. Two mold structures are disclosed. A preferred mold comprises four block members defining, in a closed position, a hollow cavity corresponding to the exterior container dimensions but movable outwardly to an open position. A plurality of spaced core members are movable into and out of the hollow cavity to, respectively, define the container mold and permit ejection of the molded container therefrom. Other apparatus features are disclosed.

Abstract: Methods are disclosed for injection molding a partitioned container having four sidewalls, an open top and a closed bottom. Thermoplastic material from a primary sprue flows through a runner system to inlet gates disposed to open into the mold cavity in a generally common plane lying at about the open top of the container to be molded and along opposed container sidewalls intermediate adjacent partition walls. Two mold structures for, inter alia, facilitating the gating method are disclosed. A preferred mold comprises four block members defining, in a closed position, a hollow cavity corresponding to the exterior container dimensions but moveable outwardly to an open position. A plurality of spaced core members are moveable into and out of the hollow cavity to, respectively, define the container mold and permit ejection of the molded container therefrom.

Abstract: A fast conched candy coating is prepared by heating fat to above the melting point thereof and mixing the fat with sugar, optionally with milk solids, emulsifiers, flavoring, cocoa or cocoa butter. The mixture is maintained above the melting point of the fat but below 150.degree.F. The heated mixture is then conched in a high speed shearing and mixing device wherein the solid particles of the mixture are sheared to 40 microns or less and the mechanical energy imparted during the shearing and mixing raise the conching temperature to between 190.degree.F and 250.degree.F in less than 30 seconds.

Abstract: A water closet seat assembly with a closet seat for use in an elevated or a conventional position. The seat assembly includes support walls mounted on opposite sides of the water closet and provided with two vertical and opposed guideways. The closet seat has a central opening for access to the receptacle and guides which project into the guideways and are free to slide and pivot therein. Support protrusions project inwardly from the support walls to support the closet seat in the elevated position. As the closet seat guides are moved to the bottom of the guideways, an extended lip portion of the closet seat which rests on the support protrusion, moves rearwardly to clear the protrusions and permit the closet seat to be lowered to its conventional position adjacent the upper edge of the water closet receptacle. Arm rests may extend from the walls to provide support for the arms of the user.

Abstract: A double walled liquefied gas container formed with an inner storage vessel and a spaced outer shell with insulation in between with a low heat conductive neck tube connecting the access opening of the inner vessel with the access opening through the outer shell with heat conductive ring members preassembled in conductive relation longitudinally spaced along the neck tube and disc members of larger dimension joined in contacting relation with the outer end portions of the ring members and in which the insulation includes layers of heat conductive material wrapped in contacting relation with the disc members and which includes means for connecting the neck tube to the access opening in the outer shell to permit relative angular and lengthwise movement between the inner vessel and outer shell and to limit relative rotational movement.

Abstract: A cheese extender comprised of a congealed mixture of a synergistic combination of sodium caseinate and potassium caseinate, fat and water. The weight ratios of the caseinates to fat are from 1:2 to 2:1 and the weight ratios of water to the total of the caseinates and fat are from 1:2 to 3:1. The ratios of the sodium caseinate to potassium caseinate are 4:1 to 1:4. The ingredients are heated to at least partially solvate the caseinates and then cooled to form the congealed mixture which closely resembles mozzarella cheese in texture and mouth-feel.

Abstract: The machine dispenses a ready-made milk shake. A freezing chamber has a dispensing valve having porting and a valve element so arranged that flow of the semi-frozen comestible and the flavoring material occurs simultaneously. A beater mixes the two during dispensing. A conduit for the flavoring material has a unique coupling to the valve block and a quick-release coupling intermediate its ends. Upon release of the latter, a manually operable sampling valve may be connected to the conduit to selectively draw a sample of the flavoring. A pump is provided for sucking in a liquid comestible and gas in a preselected proportion and delivering them to the bottom of the freezing chamber. A vent is located in the valve block to vent air from the freezing chamber upon start-up of the machine. The vent has an inlet located at a level so that the liquid and gas volumes in the chamber are about equal to the respective proportions pumped.

Abstract: Thin flexible urethane foam film layers are produced by spreading a layer of polyurethane reactants over a carrier sheet at a uniform layer thickness. The polyurethane reactants consist essentially of an isocyanate and a hydroxyl terminated polyol having an inorganic carbon dioxide producing blowing agent incorporated therein and being free of water. The unconfined film layer is then heated to a temperature in the range of from 260.degree.F to 390.degree.F to cause gellation and release of the carbon dioxide in the mixture with final formation of a uniform thickness flexible polyurethane foam product.

Abstract: An injection mold is disclosed for making an article having a plurality of side walls defining an enclosure. The mold elements during opening and closing of the mold move in a coordinated manner via mechanical interlocks. A first mold section carries plural side wall members that slide between a closed position and an open position. A second mold section interlocks with the side wall members to carry them from their closed to their open position and the side wall members are themselves linked to a stripper ring that strips the article from the mold. Other features are disclosed.
