Title: Magnetic separation method for iron carbide
Inventor: RUER JACQUES
IPC: C01B31/30
Filed: 1996-04-30
Abstract: PCT No. PCT/FR96/00658 Sec. 371 Date Jan. 20, 1998 Sec. 102(e) Date Jan. 20, 1998 PCT Filed Apr. 30, 1996 PCT Pub. No. WO96/34692 PCT Pub. Date Nov. 7, 1996A method for purifying iron carbide begins by feeding ore to a reaction chamber. A mixture of iron, iron oxides, gangue, and iron carbides is extracted from the reaction chamber. The temperature of the mixture is then adjusted to a range of 400 DEG -500 DEG  C. The mixture, at the adjusted temperature, is subjecting to a first magnetic field for separating the mixture into a magnetic fraction including iron and iron oxides from a non-magnetic fraction including gangue and iron carbides. This is followed by a cooling of the non-magnetic fraction of gangue and iron carbides below the Curie temperature of iron carbide. The gangue and iron carbides are subjecting to a second magnetic field for separating the iron carbides, that become magnetic, from the gangue that remains non-magnetic.

Title: Oven with selectively energized heating elements
Inventor: BODDY VICTOR R
IPC: F24C7/08
Filed: 1996-09-04
Abstract: An oven (10) for heating food includes a refractory slab (56) for placing a food item to be heated thereon. The refractory slab (56) is preheated to a preselected temperature by a first electric resistance heating element (54) disposed below the slab (56). The oven (10) also includes a second electric resistance heating element (44) and circulating fan (36) disposed above the food to be heated. When food is cooking, electrical power is switched from the first heating element (54) to the second heating element (44) so that both heating elements are never operated at the same time. Food is cooked by the dual action of conduction from the slab (56) and convection from the second heating element (44) and fan (36). After food is cooked, power is switched back to the first heating element (54) to maintain the slab (56) at the preselected temperature.

IPC: B29C49/22
Filed: 1997-03-06
Abstract: A multilayer plastic container having enhanced strength for high temperature and pressure applications such as the pasteurization of carbonated juice drinks. The container is commercially cost-effective in comparison to prior art pasteurizable glass containers, and provides all of the advantages of plastic over glass, i.e., lightweight, shatter-resistant, etc. In a particular embodiment, the multilayer container includes inner and outer layers of a relatively high IV virgin PET, e.g., 0.85-0.90 dl/g, and a core layer of post-consumer PET having a substantially lower IV. The container has a relatively tall and slender profile, with high orientation levels in the panel and shoulder, and an oriented thick-walled base with feet.  The base preferably has a high profile and angled foot pads which are allowed to move outwardly under creep. According to a method of making a multilayer preform for such container, an enhanced injection rate and mold pressure are utilized to enhance interlayer bonding and prevent separation of the layers in spite of their substantial differences in IV.
