Patent number: 6616847Abstract: The invention relates to a method for producing crystals from thermally sensitive solids. According to this method, the solid is dissolved in at least one solvent and the solution is concentrated by drawing off the solvent to beyond the saturation concentration of the solid, so that crystallized solids are formed. The solvent is caused to permeate a substantially semi-permeable membrane, preferably by being subjected to excess pressure. The inventive method can be carried out substantially isothermally in order to prevent the thermally sensitive crystals from being damaged.Type: GrantFiled: June 7, 2001Date of Patent: September 9, 2003Assignee: Frounhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Ulrich Teipel, Ulrich Förter-Barth

Patent number: 6616848Abstract: A die lube recovery and recycling system includes a weir tank, a filtration assembly, and a holding tank. The weir tank receives used, dirty die lube and filters large particles therefrom. Preliminarily filtered die lube is pumped through the filtration assembly and reconditioned die lube is delivered to the holding tank. A level of reconditioned die lube in the holding tank is monitored and, the die lube is replenished with fresh die lube from a fresh die lube source when the level falls below a predetermined level. A die lube pressure booster is used to withdraw die lube from the holding tank, pressurize the withdrawn die lube, and spray the pressurized die lube on a die in a casting machine.Type: GrantFiled: October 11, 2001Date of Patent: September 9, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Michael R.

Method of and system for continuously processing liquid materials, and the product processed thereby
Patent number: 6616849Abstract: The present invention proposes a method of and system for continuously processing liquid material by which enzymes in the liquid material are inactivated and the liquid material is sterilized effectively. In one example of the system according to the present invention, a liquid material is introduced into a processing chamber 11 from an introduction port at the bottom, and liquefied carbon dioxide formed into micro-particles by a filter 16 is also introduced in the chamber 11. The micro-particles of liquefied carbon dioxide dissolves into the liquid material efficiently. The liquid material taken out from a take-out port 18 is introduced into a warming pipe 20 kept at such a preset temperature and pressure where the carbon dioxide turns to a supercritical fluid. After that, the liquid material is introduced through a pressure control valve 24 into a pressure-reducing chamber 24. The carbon dioxide rapidly changes from supercritical fluid to gas, and vaporizes from the liquid material.Type: GrantFiled: May 2, 2000Date of Patent: September 9, 2003Assignee: Shimadzu CorporationInventors: Yutaka Osajima, Mitsuya Shimoda, Michinosuke Takada, Masaki Miyake -
Patent number: 6616850Abstract: A water filter for recreational vehicles (RV) is provided which includes a ceramic filter element having a radial flange attached thereto. The flange facilitates filter assembly and replacement of the filter element in the filter housing. The method of use describes a quick and easy method of replacing the filter element which is advantageous to unskilled persons in assembling and attaching the water filter to the RV.Type: GrantFiled: September 10, 2001Date of Patent: September 9, 2003Inventors: Anthony D.
