Publication number: 20180042315Abstract: A method and system are provided for cutting and placing individual nose wires in a facemask production line. A continuous wire is supplied from a source to a cutting station in the production line. At the cutting station, the wire is engaged with a set of driven feed rollers that advance the wire at a first speed to a cutting roller, wherein the wire is cut into individual nose wires. The individual nose wires from the cutting roller are then engaged by a set of delivery rollers to deposit the individual nose wires onto a running carrier web. The delivery rollers are independently driven relative to the feed rollers and cutting roller such that the nose wires from the cutting roller are initially accelerated and transported away from the cutting roller at a second speed that is greater than the first speed and then decelerated and moved onto the carrier web at a third speed that is less than the first speed.Type: ApplicationFiled: October 16, 2015Publication date: February 15, 2018Inventors: Ajay Y. Houde, David Lamar Harrington, Mark Thomas Pamperin, Nathan Craig Harris, Joseph P. Weber

Publication number: 20170009162Abstract: A rotating heat regenerator is used to recover heat from the syngas at it exits the reactor vessel of a waste or biomass gasifier. In some embodiments, three or more streams are passed through the heat exchanger. One stream is the dirty syngas, which heats the rotating material. A second stream is a cold stream that is heated as it passes through the material. A third stream is a cleaning stream, which serves to remove particulates that are collected on the rotating material as the dirty syngas passes through it. This apparatus can also be used as an auto-heat exchanger, or it can exchange heat between separate flows in the gasifier process.Type: ApplicationFiled: August 4, 2016Publication date: January 12, 2017Applicant: INENTEC INC.Inventors: Leslie Bromberg, Daniel R. Cohn, Jeffrey E. Surma, James A. Batdorf, David A. Lamar

Patent number: 9057032Abstract: The problems of the prior art are overcome by the apparatus and method disclosed herein. The reactor vessel of a plasma gasifier is operated at high pressure. To compensate for the negative effects of high pressure, various modifications to the plasma gasifier are disclosed. For example, by moving the slag, more material is exposed to the plasma, allowing better and more complete processing thereof. In some embodiments, magnetic fields are used to cause movement of the slag and molten metal within the vessel. An additional embodiment is to add microwave heating of the slag and/or the incoming material. Microwave heating can also be used as an alternative to plasma heating in a high pressure gasification system.Type: GrantFiled: May 25, 2010Date of Patent: June 16, 2015Assignee: InEnTec Inc.Inventors: Leslie Bromberg, Daniel R.

Patent number: 7298240Abstract: A device has (1) an electronic key that transmits a wireless coded signal and (2) at least one tool that can receive that signal. The coded signal is compared to a coded signal stored in said tool. If the coded signal matches the stored signal, a switch is closed for a predetermined amount of time. An on/off switch then enables the user of the tool to turn the tool on and off during the predetermined amount of time. After the predetermined amount of time, the switch is opened so that the tool can no longer be used. Opening the switch may be delayed if the tool is in use. The tool may also contain a unique identification code that can be read by various electronic means to identify the tool.Type: GrantFiled: March 8, 2005Date of Patent: November 20, 2007Inventor: David Lamar
