Patent number: 5819837Abstract: Metal is melted in an induction-heated crucible (13) on which a mold (10) with a downward-facing filling opening (26) is located in the melting position. After melting the metal, the crucible (13) and the mold (10) are jointly rotated about a horizontal axis (A--A) into a tilting position in which the molten material flows from the crucible (13) into the mold (10). In order to melt reactive metals, melting is done in a crucible (13) that is surrounded by a vacuum, this crucible being surrounded by an induction coil (15) outside of the vacuum. The mold (10) is located in a vacuum-sealed casting chamber (6) which is evacuated together with the crucible (13) prior to melting and casting is carried out by a joint tilting of the crucible (13), casting chamber (6) and mold (10) by at least 180 degrees while the vacuum is maintained.Type: GrantFiled: March 3, 1997Date of Patent: October 13, 1998Assignee: ALD Vacuum Technologies GmbHInventors: Franz Hugo, Jakob Huber, Robert Y.

Patent number: 5803936Abstract: A gasification reactor comprising of a slow turning rotation chamber (1) with tapered end pieces (7) and sealed by stationary closures (8, 9). The chamber is divided by rings (3, 3') into three sections (4, 5, 6). The first section (4) is used to dry and pre-heat the combustible material (12). Section (5) is the gasification zone and section (6) is used to collect and transport the ash to the outside of the chamber. In order to obtain a better insulation against loss of heat an inner cylinder (24) is fitted into the chamber. The feed stock material (12) is brought into the chamber with a hollow piston (13) through the stationary closure (8) and inside the chamber the material is moved along by the rotation of the chamber. Fresh air supply is introduced into the chamber through special form parts (25), and the combustible gas is collected and returned to the outside with the pipe (31). Ash and slag are lifted and deposited in a collector (21) from where they are brought to the outside.Type: GrantFiled: September 26, 1996Date of Patent: September 8, 1998Inventor: Jakob Huber

Patent number: 5626288Abstract: A method and apparatus for ventilating an enclosed air space, such as the crawl space under a building, and which includes a controller which is switchable between a cooling mode which activates a ventilating fan upon the temperature in the space reaching a predetermined upper limit and the differential of the temperatures inside and outside of the space reaching a predetermined value, and a heating mode which activates the ventilating fan upon the temperature in the space reaching a predetermined lower limit and the differential of the temperatures inside and outside of the space reaching a predetermined value. The ventilating fan may also be activated by the presence of predetermined concentrations of dangerous or destructive gases, such as radon and water vapor.Type: GrantFiled: June 6, 1995Date of Patent: May 6, 1997Inventor: Jakob Huber
