Patent number: 4092093Abstract: Apparatus and method for changing and setting a peeled, warm or hot hard-boiled egg into a desired shape, for example a cubic shape. This apparatus comprises a tubular chamber having a required inner cross sectional shape and having a threaded neck portion, a bottom plate for closing one end of the chamber, a pressing member for progressively pressing the boiled egg contained in the chamber, and a threaded cap for progressively threadably pressing the pressing member. By putting an unshelled hot egg soon after being boiled, then inserting the pressing member through an open inlet of the neck of the chamber and progressively pressing this egg thereby, and keeping this pressed state of the egg for some time while leaving it to be cooled, it is possible to obtain a boiled egg which has been changed into a shape defined by the chamber and the pressing member.Type: GrantFiled: June 16, 1976Date of Patent: May 30, 1978Assignee: Kabushiki Kaisha Aiki ShojiInventor: Masashi Nakagawa

Patent number: 4063869Abstract: In a pressure moulding machine, particularly a die casting machine, detection of locking together of the die parts by the applied pressure is effected by detecting the resulting mechanical stretch in the machine frame; the die parts are opened and closed together by an air motor associated with a hydraulic motor that damps the opening and closing movement of the dies, the die parts being locked together by the hydraulic motor; full closing of the die parts is determined by applying pressurized air to bores therein and to a controlling pressure switch, the pressure switch not being operable if air is leaking from the bores.Type: GrantFiled: December 3, 1975Date of Patent: December 20, 1977Inventor: Norbert R.

Patent number: 4060362Abstract: The disclosure is directed to a combined same cycle and subsequent cycle control of an injection molding machine. Mold cavity pressure readings are accumulated and averaged during an initial cycle portion to generate a sensed average value which is compared to a setpoint reference to test for an error. The error signal so generated is used to immediately vary the hydraulic pressure driving the injection ram during the same cycle of machine operation to cause the sensed pressure profile to be corrected to a reference pressure profile. A further correction to the hydraulic pressure is enabled as cavity pressure readings are continued to a later event, averaged, and the resulting sensed value compared to a setpoint reference to enable a further correction to be implemented during the same cycle although its effect on the process is principally effective in the next subsequent cycle.Type: GrantFiled: May 12, 1975Date of Patent: November 29, 1977Assignee: International Business Machines CorporationInventor: Charles Eugene Wilson, III

Patent number: 4060367Abstract: A mechanism for controllably driving a plunger in a dough forming apparatus of the type that has a chamber in which the plunger resides to move dough in incremental steps toward one end of the chamber. Spanning the one end of the chamber is a plurality of parallely spaced apart elongate members, the spacing between the elongate members corresponding to the thickness of a french fry shaped piece, e.g. 1/4 inch. The plunger is advanced by increments of a similar distance, the distance corresponding to the width of the french fry piece and when a plurality of dough bodies protrude through the spaces between the elongate members a single wire cutter is reciprocated across the exterior of the elongate members to sever the protruding bodies thus to form french fry shaped pieces.Type: GrantFiled: January 2, 1976Date of Patent: November 29, 1977Assignee: Ampco Foods Inc.Inventors: Mounir A. Shatila, John L. Veeneman, John H. Lach, James F. Harmon

Patent number: 4060226Abstract: A method and apparatus are disclosed for the production of injection molded products from synthetic resinous materials, such as nylon, which tend to be degraded when exposed to oxygen while they are heated to the temperatures required for injection molding. The apparatus includes a barrel having a discharge opening, a screw receiving bore and a vent opening between the feed opening and the discharge opening. A two stage rotatable reciprocable screw is mounted in the bore and includes a vented portion in registry with the vent opening. Water vapor and volatiles are generated during plasticization in the first stage of the screw, and evolve as the material enters the vent section of the second stage. The vapors are exhausted through the vent opening. The vent opening is provided with a check valve which readily permits the exhaust products to pass from the screw receiving bore. However, the check valve effectively prohibits the entrance of atmospheric air through the vent opening to the vent section.Type: GrantFiled: July 8, 1976Date of Patent: November 29, 1977Inventor: John Schweller
