A method and apparatus for removing moisture from coal and for comminuting coal.

A novel improved processing kettle is disclosed, the kettle comprising an inner hemispherical plate defining an inner lining and an outer hemispherical shell at least partially surrounding the inner plate and forming a steam-jacket space therebetween. Means are disposed through the outer shell providing entrance and egress of steam to and from the steam-jacket so as to heat a product within the kettle that is being mixed. Importantly, at least a portion of the surface of the inner plate communic...

Ferrophosphorus is heated in admixture and excess aluminum to convert the phosphorus therein to aluminum phosphide. The aluminum phosphide is hydrolyzed and an alloy comprising the nonphosphorus constituents of the ferrophosphorus and unreacted aluminum is separated from the hydrolysis products. The alloy of non-phosphorus constituents and aluminum is useful in the metallurgical industry and the phosphine obtained during the hydrolysis reaction has well-known utility as a chemical intermediate, ...

Processing apparatus for photographic material which contacts the material with a developer liquid and a fixing liquid in consecutive order, the developing liquid being applied by two spaced-apart applicator rollers partially immersed in such liquid, the first to contact the material being rotatably driven in a direction opposite to the direction of movement of the material and the second in the same direction as the material direction but at a substantially greater linear speed, and the fixing ...

This invention relates to machines for softening leather, commonly referred to as staking machines, of the type in which leather to be staked is passed between opposed interengageable processing elements the distance between which is periodically increased and decreased by relative movement of the processing elements. The leather is staked by the action of the processing elements as they approach their minimum distance apart. The construction of the machine is such that the processing elements b...

A potato processing apparatus which comprises a rotatable potato receiving means having a number of receptacles into which potatoes to be processed are rotated. At least one potato processing station is provided adjacent the receiving means and has potato compressing, cutting and removing means. Rotation of the receiving means is synchronized with operation of the processing station or stations such that with a potato rotated on a receptacle the compressing means operate to firmly lodge said pot...

In a data processing system and method, particularly for processing data derived from a gauge which is measuring the thickness of continuous metal strip issuing from a metal processing plant, the value of the measurement data is sampled at successive time instants and the sampled values are processed such as to derive their mean and standard deviations. The successive time instants are randomly or psuedo-randomly distributed in time so as to avoid the possibility of the values of the data sample...

Waxy, small granule starch of high spreadability, and waxy, large granule starch which is capable of forming an exceptionally clear and bright paste, are simultaneously produced by steeping waxy barley grain for a period of at least 12 hours in an aqueous solution containing sulfur dioxide at a temperature of 45.degree.-55.degree. C so as to swell the grain and extract soluble protein contained within said grain, water washing and milling said steeped grain, separating the starch from fibers and...

Circular sealing partitions are moved through a cylindrical vessel open at both ends and to a central portion of which a processing fluid is continuously supplied through a port in the wall of the vessel.

A develop processing apparatus is provided for processing an object with a developing solution, comprising a retaining member for rotatably retaining the object, a developing solution supply nozzle for supplying the developing solution to the object, a developing solution sucking nozzle for sucking the developing solution supplied to the object, a developing solution supply nozzle moving mechanism for moving the developing solution supply nozzle above the object, a developing solution sucking no...
