  • Publication number: 20240408805
    Abstract: A method and system is provided for operating a molding machine to prevent damage when replacing a mold. The molding machine includes movable and fixed magnetic platens to open and close a mold. The system includes a flux sensor. When a set-up mode is selected, an electronic processor is configured to: enable movement of the movable magnetic platen when the crane is above the molding machine; the molding machine receives a crane load signal that is less than a marginal load value; and the flux sensor senses that the magnetic platens are magnetized and the magnetic circuit is completed; and enable movement of the movable platen to remove/insert the mold when the crane is above the molding machine; the molding machine receives a crane load signal wherein a load is greater than the marginal load value; and the flux sensor senses that the magnetic circuit is not completed.

  • Patent number: 11685094
    Abstract: An injection molding heat removal sensing and control system and method are provided for determining and controlling a heat transfer rate for a mold in a molding machine. The system includes an inflow temperature sensor for sensing an inflow temperature for coolant provided to the mold, an outflow temperature sensor for sensing an outflow temperature for coolant exiting the mold, and a flow rate sensor for sensing a flow rate for coolant through the mold. The electronic processor is also configured to calculate a heat transfer rate for the mold from the inflow temperature, the outflow temperature, the flow rate for the coolant, and the calculated mass and the temperature of the molten plastic. The processor determines a time lag between when heat enters the mold and when heat is removed by the coolant and pre-emptively adjusts coolant flow rate to provide uniform heat transfer throughout a molding cycle. The heat transfer rate and total energy removed can be determined and provided on the display.

  • Publication number: 20060058571
    Abstract: An apparatus for generating electromagnetic waveforms to stimulate a subject includes a computing device generating digital waveform data. A digital-to-analog converter receives the digital waveform data from the computing device and generates a corresponding analog waveform signal. A channel selector having output channels is operable to apply the analog waveform signal to the output channels when the output channels are actuated. A sequencer independent of the computing device selects and actuates the output channels of the channel selector. An electromagnetic field generator is coupled to each output channel of the channel selector. The electromagnetic field generator coupled to each actuated output channel converts the analog waveform signal into an electromagnetic waveform thereby to expose a subject wearing the electromagnetic field generators to the electromagnetic waveform.

  • Patent number: 6157777
    Abstract: A fluid transport assembly transports a fluid through a fluid conduit and maintains the fluid above a predetermined temperature. A fluid line carries the fluid therein. The heater assembly includes a body with a bore and two open ends respectively disposed at each end of the bore. The fluid line is disposed within the bore and contacts the body. The heater assembly further includes a heater and at least two electrical terminals connected with the heater. The heater is disposed within the body and each terminal extends from the body.
