20090041886 | Cross-Over Nozzle System for Stack Molds - A crossover nozzle system for transferring molten plastic from an inlet at the center of the stationary platen of an injection machine to the main manifold of the molding chambers of the stack molds of the injection molding machine. The crossover nozzle system relies on molten plastic pressure within the system to actuate the primary sprue shut-off valve, and thus to open and close the flow of molten plastic to the molds. Therefore, a drool-free valve mechanism is created without needing an external actuation of the shut-off valve like, for instance, a hydraulic or a pneumatic cylinder. | 02-12-2009 |
20110086124 | CROSS-OVER NOZZLE SYSTEM FOR STACK MOLDS - A crossover nozzle system for transferring molten plastic from an inlet at the center of the stationary platen of an injection machine to the main manifold of the molding chambers of the stack molds of the injection molding machine. The crossover nozzle system incorporates liquid cooling to create a high viscosity viscous seal from molten plastic at a parting line between moveable components. Accordingly, no other seal is required between the components. | 04-14-2011 |

20090220725 | CLOSING AND DAMPING DISKS - The invention refers to closing and damping disks, designed to fit gas compressor valves. According to this invention, the disks are made of both one wearing layer (d) with a thickness of 0.1-0.3 mm and one layer made of an antifriction material (e). They have a centering hole (b), some slots (a) marked out by some arc-shaped walls, at least one blocking hole (c) preventing disk's rotation inside the valve, so that the disk could be used on both sides in turn, and some beams (l) of equal strength resulting from the material remaining at the end of the slots (a). | 09-03-2009 |
