Abstract: A machine for imprinting patterns onto uncured concrete in an elongated bed includes a frame for positioning the finishing machine over the bed. A lower patterning unit suspended from the frame is movable backward and forward of the concrete bed and a press assembly moves the pattern in and out of contact with uncured concrete on the elongated bed.

Abstract: A molding device for pre-shaped plastic films has a body, a platform and a driving shaft. The body can be rotatably mounted in a pre-shape machine and has an annular side surface and a top opening. The platform is detachably mounted in the top opening of the body. The driving shaft is mounted longitudinally through the body, movably extends longitudinally relative to the body and has an end attached securely to the platform to selectively raise the platform to lift a pre-shaped plastic film from the body. Accordingly, the plastic films can easily be separated from the platform, and to manually separate the plastic film from the molding device is unnecessary to prevent the plastic films from being damaged.

Abstract: A blown film die divides a flow of material into two flows with higher and lower flow portions and recombines the flow by combining higher flow portions with lower flow portions. The flow can be divided in circumferential channels between an annular feed ring and an annular distribution ring.

Abstract: A method and system of forming a fire door core are provided. Hydraulic binder and resin are supplied from raw material bins and mixed to provide a submixture. Exfoliated vermiculite is then mixed with the submixture to provide a mixture that is deposited into a plurality of compression molds. Each of the filled molds are pressed in a press at a predetermined temperature at a predetermined pressure for a predetermined period of time sufficient to harden the mixture into a hardened slab. The hardened slabs are then removed from the molds, impregnated with water or steam in a water impregnation assembly and dried in a drying assembly.

Abstract: An apparatus for automatically producing ice vessels. Ice masses produced by ice making machine 3 is crushed to pieces by ice crusher 1. Then, the ice pieces are fed from an outlet chute 2A of the ice crusher 1 to one of female dies 12, which are provided on an endless conveyor 11. A male die 15 provided adjacent the ice crusher 1 is lowered to be depressed to the female die 12, thus molding ice vessel A. The molded ice vessels A are then transported in sequence to a terminal side 11A, at which they are detached from the female die 12 by a collecting plate 21 and then transported. According to the invention, there can be provided an apparatus which can make ice in proper quantities and is suited for mass production of ice vessels.

Abstract: A frame (10) carries horizontal, parallel, journaled, cylindrical bearings (26, 28), upon which rotatably rests the cylindrical external surface a wheel (30) having, on its outside periphery, ports (44) communicating with respective moulds (45) which are radially arranged side by side in the wheel. Plungers (46) are slidably received in the moulds. Feeder (52) stationary with respect to the wheel (30) deliver pasta filata into at least one of the ports. Ejectors (48, 50) stationary with respect to the wheel (30) eject pasta filata from at least one of said moulds (45) through its associate port. A motor (42, 43) with transmission (38, 40, 41) moves said wheel (30) in steps corresponding to the interval between two successive ports along the periphery of the wheel. Jets (66) sprinkle the moulds with chilled water.

Abstract: Apparatus for portioning, shaping and dispensing a plurality of molded, spherically shaped meatballs includes a food product entry area communicating with a compression chamber for compression and movement of the food product into a positioning area wherein it is given a rod-like shape and moved to a shaping area wherein it is given a spherical shape and dispensed into a suitable receiving means.

Abstract: An apparatus and method are disclosed for a continuous compressing operation involving receiving pliable articles, compressing them along a single axis, and releasing them once compresssed. The apparatus and method each involve the use of a pair of disks arranged in a V-shaped configuration, with their opposing surfaces contoured to form opposing recesses which, together with a flexible barrier spanning the space between the disks, define a pocket opening toward the rims of the disks for receiving the article and retaining it during compression. The disks are rotated while maintaining the V shape, thereby causing the pocket and hence the retained article to become compressed. Once the narrowest point of the V is passed, the compressed article is released by gravitational force.

Abstract: The molding machine of the present invention comprises a screw extruder for extruding plastic material. A plurality of molds are moved one at a time to the outlet end of the extruder for receiving the plastic material therefrom. One end of the mold is open for receiving the plastic material and the opposite end of the mold includes a closure plate covering the end of the mold. The closure plate has a small fill sensing aperture therein. A sensing switch is mounted adjacent the fill sensing aperture and is adapted to sense when molded plastic exits from the fill sensing aperture so as to shut off the extruder and cause the mold to move away from the extruder so that an additional mold can be filled. A cylinder operated closure device clamps the opposite ends of the mold after the mold has moved away from the filling station so as to contain the plastic material within the mold while the plastic material cools and hardens.

Abstract: An apparatus and method are provided for making diamonds. In one form, a plurality of shock waves are generated and are directed or focused against carbon particles retained in a cavity of a die such that the heat and pressure of the shock waves will heat and compress the particles of carbon to form one or more diamonds thereof. In another form, diamonds or particles of diamond dust are disposed in a cavity containing carbon particles and serve as substrates or nuclei on which carbon is converted to diamond forming larger diamonds thereof. Each of the diamonds disposed in the mold or die cavity is completely surrounded by carbon. A magnetic jack hammer of the type disclosed in U.S. Pat. No. 3,632,242 having a focusing horn attached thereto is employed to generate and transmit the trains of intermittent shock waves to the diamonds and carbon disposed in the mold.

Abstract: An automated molding apparatus having a continuous movable belt trained about a pair of spaced apart sprocket pulleys rotatably mounted to a main support frame. A plurality of female dies are equidistantly mounted to the belt for mating with a plurality of male dies reciprocatively mounted in a plane above the female dies. A heated feeder is provided for introducing a predetermined amount of melted mix into the female dies prior to mating with the male dies. To insure that the resulting molded product is properly hardened, the female dies are adapted with internal channels connected to a liquid cooling system. The molding apparatus is readily adaptable for hydraulic operation and may be readily automated by an electrically actuated control and timing system.
