Abstract: The manufacture of moldable concrete products with deferred mold release incorporates molding means bm1 into optimized rotary structures 1, 5, 7, 9, 12 in the form of modular cylinders having at least two faces, the cylinders being equipped and/or associated with means which group together the main work-stations MP, MT, B, D, NH so as to assign a rotary travel of more than 270.degree. and preferably equal to 360.degree. to the curing of the molded material with or without recourse to any means for accelerating the curing.

Abstract: Production machinery for handling plastics injection mold parts up-ended has a pair of article manipulating devices having article attachment faces to which mold parts are attachable. One of the pair is translatably movable to move the mold parts clear of each other and the attachment faces are associated with slewing rings at an angle, e.g. 45.degree., to the attachment faces to enable the mold parts to be turned from a working disposition to a cleaning, repair, or other disposition.

Abstract: In an apparatus for producing moulded articles, particularly of plastic, by means of a mould formed from individual mould parts (3, 4, 5) optionally fixed to mounting surfaces, support parts, etc and which, following a closed position, move during the moulding process into an open position by a stroke c in a direction x a working device, e.g. a demoulding, charging, cleaning and/or similar device is introduced into the gap (6, 7) formed between the faces of the mould parts. With at least two mould parts (3, 4 and/or 5) is associated in each case a slide (I, II and/or III) movable by a stroke d in a y-direction for introducing the working devices. As a function of the movement of at least one mould part (3, 4 and/or 5), or its mounting surface (1, 2), support part (18, 19), etc, the slide (I, II and/or III) perform the stroke d in the y-direction.

Abstract: A mold press having a mold cleaning device with a rotary brush mounted on an arm adjustable for cleaning in directions parallel to the mold surface, toward and away therefrom, and in a wiping motion relative to the surface.

Abstract: An apparatus for compacting a solid waste material includes a hollow cylindrical body having a charging inlet for charging the solid waste material therethrough into the hollow cylindrical body, a heating portion for heating the solid waste material in the hollow cylindrical body, and a discharging outlet for discharging the solid waste material from the hollow cylindrical body; a rotatable shaft disposed in the hollow cylindrical body and having a helical screw blade thereon, the screw blade and an inner wall surface of the hollow cylindrical body being spaced from each other with a clearance provided therebetween for allowing the solid waste material in the hollow cylindrical body to form a bridge therein; a support for radially movably supporting an end of the rotatable shaft; a prime mover coupled to the end of the rotatable shaft through the support; and an outlet nozzle coupled to the discharging outlet for compressing the solid waste material discharged from the discharging outlet.

Abstract: A press for molding concrete products comprising a vibrating table, a mold adapted to be put on the vibrating table and to be filled with concrete, a concrete feeding means such as a hopper and means provided between the hopper and the mold to fill the mold with a given amount of concrete, said mold filling means comprising an endless belt conveyor arranged below the hopper and including belt-driving means, and means for bodily displacing the conveyor in a linear reciprocating motion so as to move the forward end of the conveyor above the mold and to bring it back to an initial position.

Abstract: Alfalfa pelletizing apparatus and method wherein pellets are formed in an open ended molding passage or aperture by compressing members entering both ends of the aperture to compress the alfalfa and to extract liquid content for discharge at a passage communicating with the mid portion of the primary mold aperture. The mold apertures are formed in a moving belt upon which the alfalfa is discharged. The pellets are expelled from the apertures after formation thereof and the forming apertures are then cleaned after release of the pellets.

Abstract: An apparatus for cleaning parting surfaces of plastic molds, which ensures complete and efficient removal of the flash adhered to the parting surfaces of the mold. The cleaning apparatus comprises a carriage reciprocatably mounted on a supporting assembly, and cleaning means mounted on the carriage. The cleaning means comprises a pair of cleaning heads each comprising a spaced pair of air blasting members and a rotary brush arranged between said air blasting members, both of which are provided in the head body. The air blasting members blast the air against the respective parting surfaces of the mold sections, and the rotary brushes remove the flash from the respective parting surfaces. The removed flash dust is sucked up and collected by a dust collecting member provided in the head body and connected to suction means.

Abstract: Extruder and twin roller calendering plant for producing films or sheets of synthetic plastics or rubber material comprising a pair of calendering rollers mounted in a calender frame and an extruder nozzle head directed into the gap between the pair of calendering rollers, the calender frame being pivotally mounted such that it can be pivoted away from the extruder nozzle head to allow ready access to the extruder nozzle head. The calender frame may be pivotally mounted on the nozzle head and a counter balance weight and/or the drive motor for rollers can be mounted on an opposite side of the pivot to the rollers thereby to counter balance the weight of the rollers.

Abstract: Method and apparatus for cleaning a tire curing mold by immersion in liquid cleaning agent bath, wherein the complete upper assembly of the mold is immersed in the bath and slowly rotated. Super or ultrasonic energy sources are particularly located and aimed, so that in combination with the relative motion of the mold assembly relative to the sources no portion of the surfaces to be cleaned is hidden by any other part from the direct impingement thereon of the sound wave energy. Efficiency of mold cleaning is materially advanced.
