Abstract: A combination medication mold and dispenser. The medication is poured into a multicompartment tray and solidifies into troches. The tray is made of a flexible plastic which can be bent to release the troches individually. The tray has a cover attached with a flexible hinge to protect the troches after preparation. The medication can be prepared and dispensed to the patient in the same container. The covered tray can be held in a sleeve to further protect the medication and hold the cover in place.

Abstract: A mold for forming a plastic closure includes a first mold part defining a female cavity and a second mold part defining a male mold cavity surface, with the second mold part including a core having a knock-out pin reciprocated therein and surrounded by a fixed sleeve which cooperate to define a tamper-evident band on the cavity for the closure. Vents are provided for venting the lower edge of the cavity during the ejection-molding process. Also, the knock-out pin has a lubricant pocket formed on the peripheral surface thereof.

Abstract: For automotive interior trim molding assemblies having a vinyl skin shell, a reinforcement insert, and an intermediate reaction type polyurethane foam composition, a vinyl skin shell which has a gasket-type peripheral edge formed thereon for abutting cooperation with the reinforcement insert to prevent leakage of the foam therepast during the foam reaction period in a reaction mold. The gasket-type peripheral edge is formed on the otherwise thin shell by a tear edge, against which plastisol builds up in a substantially triangular cross section during the shell molding period in a heated slush mold.

Abstract: A method of integrally molding a member to be molded onto a portion of a rigid member, which method is applied to manufacture of a connecting rod used in a crank device of a wiper system in a motor vehicle, for example. In this method of molding, a portion to be positioned is formed in the rigid member, a portion of the rigid member is inserted into a cavity for molding the member to be molded in such a manner that the portion to be positioned is exposed in the cavity, positioning members linearly movably provided in this cavity are engaged with this portion to be positioned to effect positioning, the positioning members are retracted to the outside of the portion to be positioned after the positioning, and thereafter, a molding material is poured into the cavity to mold the member to be molded.

Abstract: Method for molding a composite metal-elastomer styled wheel in which a middle mold part consists of a metal wheel disc and rim subassembly. A base mold part seats against the outboard face of the metal wheel in the closed condition of the mold and has a mold cavity surface to provide an ornamental configuration for the outboard face of the plastic body of the composite wheel. There is a clamp which includes a funnel adapted for registry with a liquid reaction mixture injection nozzle coupled with injecting mixing apparatus. The funnel has a nozzle passage registering with a pour opening in the disc in the closed condition of the mold. A sprue pin is affixed to the base mold part in juxtaposed relation to the disc pour opening and cooperates with the margin of the pour opening to define a restricted access opening to the mold cavity during the injection pour of the urethane reaction mixture. The sprue pin is operable to restrict back-flow of the reaction material during gelation of the same in the cure cycle.

Abstract: An electric power generating set for a fluid pipeline, comprising a turbine coupled to the pipeline for rotating under the pressure of the fluid moving in the pipeline; a generator coupled to the downstream end of the turbine for generating electric power upon rotation, and a heat exchanger for communicating the fluid from the turbine to the pipeline for absorbing heat from the generator.

Abstract: An apparatus is disclosed for selectively separating runners and molded products from an injection mold assembly. The apparatus comprises first and second mold portions having mating surfaces formed to define a runner channel and product cavity. A plurality of ejector pins are disposed within the second mold portion and adapted to translate within the second mold portion so as to retractably extend into the cavities for forming the runner and molded product. An ejector plate assembly is provided which translates the ejector pins a predetermined distance within the mold. A pin extension mechanism is connected to the ejector plate assembly and at least one ejector pin. The pin extension mechanism is adapted to selectively extend the connected ejector pin a predetermined distance beyond the stroke of the ejector plate assembly such that the connected pin is extended into contact with the channels for forming the runner, or the molded product.

Abstract: Apparatus and a method are described for providing positive location openings within a contoured panel. These openings are utilized in conjunction with appropriate locators to assure that positive alignment of the molded panel in subsequent manufacturing operations is obtained. The specific die and headline constructions are likewise disclosed.

Abstract: An ice cube tray having a removable cover for sealing the tray when filled with water. The cover has a fill spout and a cover for the fill spout that cooperate with similar trays for stacking purposes.

Abstract: A form for molding building wall panels of a concrete material, wherein the form has a rectangular shallow box shape for receiving and enclosing the material while it hardens, the form having a plurality of elongated inserts extending broadwise therethrough in parallelism and on a horizontal plane to form a break line in the panel, and prestressed tension rods or post tensioned cable means extending through the form to be embedded in the material at at least one side of the break line to cause the panel to split along the break line when the rods are removed after the material has hardened.

Abstract: A method of making investment shell molds by the lost pattern process characterized in that a strand such as wire or the like is wound circumferentially about a pattern assembly in at least one location before it is coated with refractory material to form a mold shell. Thereafter, the strand is unwound to separate the shell into segments, each of which is usable as a mold.

Abstract: A mold box and mold head that are interfitted together to mold concrete blocks. The mold box has two sides and two ends forming a continuous flange around it and two laterally spaced partitions equally spaced between the two ends, one partition being in the form of a straight bar, and the other, in the form of three spaced boss members. Upwardly-extending bosses that are generally plate-like are fixed to rods which extend across laterally, parallel to the ends. The head is made up of a plate-like member having spaced plate-like members attached to it. The spaced plate-like members cooperate with the partitions in the mold box to form a concrete block therein. The resulting block is tongued on one side and grooved on the other and the top is tongued and the bottom grooved for interlocking purposes. The interior section contains three rows of cells providing greater insulation and saving of material.

Abstract: A mold for fabricating articles formed of a fluent material, especially rubber, comprising at least two mold parts enclosing a mold compartment. One of the mold parts possessing a tear or break groove at the region of the mold parting plane, the tear groove surrounding the mold compartment. The tear groove provided in said one mold part has an inner wall which is located exactly opposite the marginal or outer rim of the mold compartment formed in the other mold part and encloses an angle of about 90.degree. or less with the mold parting plane.
