Patent number: 9719149Abstract: A load transport mechanism for moving a heat treating load in a multi-station heat treating system is disclosed. The transport mechanism has a compact construction that allows it to fit in a centrally located stationary transport chamber. The transport chamber is adapted to provide ready access to multiple treating chambers arrayed around the chamber. The transport mechanism includes a load translation mechanism for moving the load linearly and a load rotation mechanism for rotating the load within the transport chamber. A multi-station heat treating system having a centrally located quenching chamber that includes the load transport mechanism is also disclosed.Type: GrantFiled: December 21, 2012Date of Patent: August 1, 2017Assignee: IPSEN, INC.Inventors: Craig A.

Patent number: 9617611Abstract: A process for quenching heat treated metal parts using a liquid quenchant and high pressure is disclosed. In general, the process includes the steps of providing a load of heat treated metal parts in a pressure vessel wherein the load is at an elevated temperature after being heat treated. In a subsequent step, a liquid quenchant is injected into the pressure vessel such that a vapor of the liquid quenchant forms rapidly in the pressure vessel and cools the metal parts. The step of injecting the liquid quenchant into the pressure vessel is continued for a time sufficient to establish a desired peak vapor pressure in the pressure vessel. An apparatus for carrying out the disclosed process is also described.Type: GrantFiled: March 22, 2012Date of Patent: April 11, 2017Assignee: IPSEN, INC.Inventors: Werner Hendrik Grobler, Bernd Edenhofer, Craig A.

Patent number: 9458519Abstract: A process and apparatus for quenching a metal workload from an elevated heat treating temperature are disclosed. The process includes the step of flowing a vegetable oil quenchant over the metal workload to provide a cooling rate sufficient to transform the metal substantially completely to a desired second phase comprising martensite, bainite, pearlite, or a combination thereof within a preselected time period. The apparatus includes a quenching chamber that has a base, an upper housing, a door, and an associated actuator for opening and closing the quenching chamber. The apparatus also includes a vessel for holding a volume of a vegetable oil quenchant, means for conducting the vegetable oil quenchant from the vessel to the quenching chamber, and means disposed in the quenching chamber for flowing the vegetable oil quenchant over a metal workload disposed in the quenching chamber.Type: GrantFiled: September 11, 2013Date of Patent: October 4, 2016Assignee: IPSEN, INC.Inventors: Aymeric Goldsteinas, Werner Hendrik Grobler
