Patent number: 9746241Abstract: Methods and apparatuses for drying electronic devices are disclosed. Embodiments include methods and apparatuses that heat and decrease pressure within the electronic device. Some embodiments increase and decrease pressure while adding heat energy, such as by using a heated platen in contact with the electronic device or by supplying a gas (e.g., air), which may be heated, into the interior of the electronic device. Embodiments include heating the gas supplied into the interior of the electronic device with pump used to decrease pressure within the electronic device and/or a separate heater. Still other embodiments include controlling the temperature of the gas supplied into the electronic device. Still further embodiments automatically control, such as by using an electronic processor, some or all aspects of the drying of the electronic device.Type: GrantFiled: April 4, 2017Date of Patent: August 29, 2017Assignee: Revive Electronics, LLCInventors: Reuben Zielinski, Joel Trusty, David Douberteen, Mark Earle, Imran Arain

Patent number: 9625210Abstract: This application discloses devices, articles, and methods useful for producing lyophilized cakes of solutes. The devices and articles provide for a method of freezing liquid solutions of the solute by the top and the bottom of the solution simultaneously and at approximately the same rate. The as frozen solution can then provide a lyophilized cake of the solutes with large and uniform pores.Type: GrantFiled: November 17, 2014Date of Patent: April 18, 2017Assignees: BAXTER INTERNATIONAL INC., BAXTER HEALTHCARE SAInventors: Wei-Youh Kuu, Mark J. Doty, William S. Hurst, Christine L. Rebbeck

Patent number: 9422389Abstract: The invention relates to processes for preparing a synthetic foam having present therein particles with a controlled particle distribution and the use of said foam, as well as to foams as such. Accordingly the invention is directed to a process for preparing a synthetic foam having present therein particles, wherein the distribution of said particles is controlled by the following steps of dissolving at least one synthetic polymer in one or more solvents to form a solution; contacting particles with said solution to form a polymer/particles mixture; and freeze-drying the polymer/particles mixture by: freezing the polymer/particles mixture; and subsequently subliming the one or more solvents to form a synthetic foam comprising said particles.Type: GrantFiled: October 1, 2012Date of Patent: August 23, 2016Assignee: STRYKER EUROPEAN HOLDINGS I, LLCInventors: Bhushan Chandrashekhar-Bhat, Martin Franke Tooren, Robbert Arnold De Graaf, Romke Stephan Rudolf Ribbels

Patent number: 9255732Abstract: A dryer includes a sealed drum, a heat pump system, a vacuum device and a steam generating device. The steam generating device connects with the interior of the drum to introduce hot steam into the interior of the drum. The vacuum device connects with the interior of the drum. The heat pump system is arranged external to the drum. Heat generated by the heat pump device is exchanged with the outer surface of the drum through a liquid medium so as to heat the wet clothes in the drum. Simultaneously, damp-hot air mixed with the water vapor in pumped from heating clothes in the drum by the vacuum device and the hot steam pumped into the drum and contacted with clothes are cooled and condensed into water. The water produced by damp-hot air is connected with water provided by the steam generating device.Type: GrantFiled: June 23, 2011Date of Patent: February 9, 2016Assignees: HAIER GROUP CORPORATION, QINGDAO HAIER WASHING MACHINE CO., LTD.Inventors: Hai Shu, Peishi Lv, Jindong Bing, Rongfeng Cheng
