Patent EP-0218066-A1 (EP)
Inventor: GEUENS LUC
IPC: C02F1/28
Filed: 1986-08-22
Abstract: Wastewater from various sources may be purified by contacting it with sludge derived from an oxidative biological water purification process and subsequently subjected to a complete anaerobic fermentation step followed by a dying-off step. A variety of contaminants such as metals, colorants, detergents, phenols and the like may be adsorbed by the sludge in this way and removed from the wastewater by separating the sludge and wastewater after contact. The process may serve as an introductory step to a normal oxidative biological water purification process. In a special embodiment, cationic contaminants are removed from the wastewater, with the aid of a sludge of the aforesaid type, whilst anionic contaminents are removed with the aid of a sludge of the same type that has been pretreated with a cationic detergent.

Title: High temperature vacuum steam distillation process to purify and increase the frylife of edible oils
Inventor: SCAVONE TIMOTHY ALAN
IPC: B01D3/38
Filed: 1986-11-27
Abstract: Deaerated oil having a level of less than about 0.10% by volume of dissolved oxygen is heated at a temperature between about 530°F (277°C) and about 650°F (343°C) and stripped with a stripping medium with a molar ratio of stripping medium to oil of between about 0.05 and about 9.7, at an absolute pressure of between about 0.5 mm Hg and about 50 mm Hg., for a time of between about 5 seconds and about 15 minutes. The combination of stripping parameters is selected so that the stripping factor "f" is greater than about 0.6, where f = KP v S/PO, where K is between about 1 and about 200, and where P v  (the vapor pressure of the component to be stripped) is not more than about 0.1 mm Hg at 500°F (277°C) and not more than about 2.0 mm Hg at 600°F (343°C). This vacuum steam stripping at very high temperatures for short residence times improves the frylife of the edible oil while minimizing undesirable thermally induced side reactions such as polymerization, trans-isomerization and hydrolysis.

Filed: 1986-07-22
Abstract: A method is disclosed for forming a surface hardenable cast iron article by development of metastable retained austenite in the cell boundary of a ductile or semiductile cast iron. The method comprises (a) controlling the solidification of a cast iron melt to extend the eutectic arrest time to 4-12 minutes, the melt having by weight percent a carbon equivalent (carbon plus one-third silicon) equal to 4.3-5.0, manganese .55-1.2, nickel .5-3.0, and the remainder essentially iron, the melt having been treated to form cell boundaries in the solidified iron with a high proportion of the manganese being segregated in the cell boundaries; (b) subjecting the solidified cast iron to an austempering heat treatment to permit the segregated manganese in the cell boundaries to form metastable retained austenite; and (c) terminating the heat treatment prior to the conversion of the metastable austenite to a stable microstructure. To obtain the benefits of wear resistance, the method further comprises using the heat treated cast iron by stressing a surface region thereof and transforming the microstructure of such surface region to martensite.

Title: Magnetically enhanced variable reluctance motor systems.
Inventor: MASTROMATTEI ROBERT
IPC: H02K1/14
Filed: 1987-06-04
Abstract: Electrically-energized salient stator poles of a variable reluctance motor terminate in stator teeth that oppose the rotor on a rotor surface. Permanent magnets located between adjacent stator teeth, and magnetized transverse to the stator to rotor gap, enhance the motor torque relative to the applied excitation in ampere-turns. Permanent magnets on the rotor are avoided by reversing the magnetization of the permanent magnets from pole to pole and energizing the pole windings to oppose the magnets in four phases 1 1 0 0, 0 1 1 0, 0 0 1 1, 1 0 0 1 during successive steps. In one embodiment, a linear motor utilizes the system by replacing the rotor with a linear actuator.

Abstract: The invention relates to a process to clear the coaxially running flame area of a directly fired rotary drum furnace (1) for drying and heating bulk material (5), in particular grain-graded mineral substances or granulates made of mineral substances and bituminous binders by means of shovels (3) which are arranged in the direction of rotation, are partially open to the inner circumference (2) of the rotary drum furnace (1) and the edge limits of which form scooping edges (3.5), as well as the design and arrangement of shovels (3) in a directly fired rotary drum furnace (1) with uniform separation over its inner circumference (2). Criteria of these inventions are a) the reduction of the degree of filling of the shovels (3), occurring at constant material feed, to a given filling volume which allows greater mobility of the material inside the shovels and thus promotes heat transmission by contact to the material; b) prevention of shovel emptying until quadrant II of the rotary drum furnace (1) is reached; c) the special design of the rear wall (3.1) of the respectively leading shovel (3) with an indentation forming a channel (3.2) which receives the discarded residual volume of the bulk material (5), avoiding development of spraying grain and d) the necessary free space for the development of the coaxially running flame area is produced. <IMAGE>
