  • Patent number: 10631554
    Abstract: A process for making an alcohol-containing frozen comestible substantially devoid of ice crystal agglomerations and/or ice crystal striations and/or trapped air and/or liquids and products thereof is provided. The process comprises rapidly solidifying an alcohol-containing liquid composition so as to produce a substantially single-phase solid alcohol-containing admixture. The single-phase solid alcohol-containing admixture, and/or pieces thereof, is then tempered by raising the temperature thereof so as to soften the single-phase solid alcohol-containing admixture and/or meld the pieces thereof into a single tempered mass. The single tempered mass is then re-hardened by reducing the temperature thereof. Also, a process for incorporating the single-phase solid frozen alcohol-containing admixture into a non-alcohol-containing composition is provided.

    Abstract: A system is proposed for encapsulating in plastics material leadframe items comprising an IC wired to a leadframe. Dust of the plastics material is removed from the encapsulation system, and in particular from those items where dust principally accumulates, such as the surfaces of the moulds. To reduce the level of dust which enters the moulding region, the path along which the leadframe items are conveyed to the moulding region is closed at times when the leadframe items are not being transported there. Additionally, the leadframe items are conveyed to the moulding region under a cover including a vacuum source, so that the dust is continually sucked away from them.

    Abstract: The injection molding machine comprises the closing mechanism 5 having the nozzle touch member 3 to close the tip opening 1a of the nozzle 1 and the electric heater 6 to regulate the temperature of the nozzle touch member 3. The closing member 5 is constituted in such a manner as the arm 13 is pivotally supported on the jacket cover 11 mounted on the nozzle 1, the cylinder 7 is mounted on mounting member 14 provided at the tip of the arm 13, and the nozzle touch member 3 is supported at the tip of the piston rod 7a. The electric heater 6 is arranged around the nozzle touch member 3. When the arm 13 is rotated from the retreated position R to the closed position C by the actuation of the rotor 8, the nozzle touch member 3 is faced to the tip opening 1a of the nozzle 1, and by extending the cylinder 7, the nozzle touch member 3 regulated to the temperature suitable for the resin material by the electric heater 6 closes the tip opening 1a from its front surface.

  • Patent number: 6015281
    Abstract: In an injection molding machine, a fixed platen 2 is provided with an air cylinder 11 through a bracket 13 and a nozzle touch plate 10 is coupled to an end of a piston rod 12 of the air cylinder 11. The piston rod 12 is extendably and contractedly driven so that the nozzle touch plate 10 is moved forward and backward between a closed position where the tip opening 9a of the nozzle 9 can be closed and a retreated position where the opening 9a can be opened. On the nozzle touch plate 10, a spherical recess portion slightly larger in radius than the tip sphere of the nozzle 9 is formed as an abutment portion 10a, and a heater 14 for adjusting the temperature is disposed in the nozzle touch plate 10. Alternatively, a passage may be formed in the nozzle touch plate 10 so that a medium of an optimum temperature can be circulated and supplied.

  • Patent number: 6007316
    Abstract: A method of and an apparatus for molding resin to seal electronic parts are adapted to use molding units to seal with molded resin materials electronic parts that are mounted on lead frames. Additional molding units are detachably mounted with respect to an already provided first molding unit in the molding apparatus, so that the number of the molding units can be arbitrarily adjusted. In this manner, the method and apparatus can be easily reconfigured or rearranged to be adapted to mass production or small production runs of the same or different types of molded parts. By simultaneously carrying out various process steps, the overall process time is reduced.

  • Patent number: 5498380
    Abstract: A plastic resin kneading/extruding method using one auxiliary equipment including a screw drive source and a resin feed hopper, and a plurality of extruding units each including a cylinder with a feed opening and a screw and having their operations composed of an extruding step of kneading and extruding the plastic resin and a cleaning step of cleaning the screw and the cylinder, characterized in that the extruding step and the cleaning step are sequentially alternated for each of the extruding units. Thus, it is possible to realize a kneading/extruding method and an apparatus therefor, which can accomplish synthetically continuous extruding operations without the extruding step zone being interrupted by the cleaning step zone and which can eliminate the defects of the prior art thereby to have a high extruding efficiency.

  • Patent number: 5427517
    Abstract: Clogging and prolonged down times are avoided in a pelletizer for paste type materials such as sludge by providing an extruder hopper with at least one, preferably two, lower edge slide gates which can be opened to permit movement of a clogged screen zone out of alignment with the discharge opening of the hopper. The clogging material can be scraped off from the screen portion that is taken out of alignment with the hopper discharge opening. The cutting of the extruded sludge is accomplished by an oscillating lower screen section that slides back and forth below the upper screen section. The upper screen section is provided with two, preferably three zones, two of which are perforated and one of which is unperforated to form a closure for the hopper discharge opening. Screeding non-pelletizable material off the screen surface is accomplished either by a separate screeding device or by operating the slide gate or gates as screeds.
