A method for the gaseous reduction of particulate ores to metals in a moving bed, vertical shaft reactor using a reducing gas externally supplied from a solid or liquid fossil fuel gasification unit. The reducing gas is reformed in a reforming zone located within the reactor and treated prior to injection into the reduction zone of the reactor. A portion of the reducing gas produced in a coal gasi...

This invention relates to a method and apparatus for the separation of finely divided solid particles dissimilar in size and/or density in a liquid, such as platelets and other blood cells in a blood sample. The separation of, for instance, platelets is accomplished by subjecting the blood sample to centrifugal force in a rotatable chamber while displacing the platelets from the blood sample by in...

The hammer mill for treating scrap metal including a rotary hammer means for delivering impact blows to scrap metal is shown. Discharge grates are provided for disposing of the scrap metal through discharge outlets for the hammer mill. The rotor is a disc type with rotating hammers located on pins extending through the discs. A plurality of caps are circumferentially located around each disc and a...

An x-ray source for use in computerized tomographic applications focuses an electron beam (14) on an arcuate anode ring (15) to produce an x-ray beam which passes through a planar slice of the subject (20) under study. Because it is very difficult to focus and to bend an electron beam having a cross section with other than cylindrical symmetry, and because it is highly desirable that the cross sec...

The partition wall supports at least a bearing for the transmission output shaft extending through the open forward end, the bearing on the partitio...

1. A process for the elimination or avoidance of troublesome edge displacement on the impacting faces of tube ends (1) that are to be joined together by means of a welded seam, in which each of the tube ends (1) is pushed on to a sizing plug (5) combined with a press die (3) and thereby the face of the tube end (1) is provided with a profile for the welding seam by compression against an end face ...

PURPOSE:To decrease the terms of work for buried inductive lines and to decrease the cost, by running the car on a course having no inductive line by means of a running pattern of a storage device after running along the inductive line. CONSTITUTION:A course storage device stores a steering angle of a time series corresponding to a lateral direction running pattern of a b c. A course NO.2 is assum...

A method of preparing a lager beer having a mild, bland, less aromatic character comprises conducting the fermentation of the wort under suitable conditions to maintain the dissolved carbon dioxide concentration in the fermenting wort at about 2.1 to about 4.0 cc of dissolved carbon dioxide per cc of wort. The fermentation of the wort is conducted for 60 to 200 hours at a temperature of 60 DEG to...

Foams having aspartase-producing microorganisms bound to the foam are made from polyurethane prepolymers which are capped with polyisocyanates, including diisocyanates, derived from methylene-bis (phenyl isocyanate) which is commonly known as MDI. These MDI based foams are hydrolysis resistant as compared to the previously used TDI based foams. The foams can be used to produce L-aspartic acid unde...

A curing rim comprising two abutting, coaxial, relatively rotatable sleeves (11, 12), one having radially inward bosses (20) and the other having axially projecting hooks (21) which can rotate into engagement with the bosses to prevent axial displacement between the sleeves. A latch hook (30) is pivoted to one of the hooks and resiliently engages the apposed boss to prevent rotation between the sl...
