摘要:
A stable combustion fuel emulsion of a petroleum fuel having a small percentage of water dispersed therein as droplets of a size of about 0.5 micron, or less, formed by high energy rotary impact milling the petroleum fuel and water together.

Chrome plated plastic scrap is chopped into small pieces and then, while subjected to sub-zero temperatures, is centrifugally impacted thereby producing a mixture of particles of chrome and plastic. Most of the chrome particles are removed by subjecting the mixture to a magnetic field. The remaining, mostly plastic particles are classified to obtain usable, predominantly plastic particles within a predetermined size range, those particles exceeding this range being, if desired, recycled for subjection to said centrifugal impacting step. The usable particles are thus reclaimed for reuse, after repelletizing, in extrusion or molding techniques.

The formation of composite materials is disclosed, using high energy rotary impact milling. The illustrations utilize polymer resin particles as the matrix material, and solid particle fillers. Ultra-small particle sizes are used for both the matrix and filler materials. When the resultant materials are processed by usual forming techniques, the resultant composite materials possess strength properties approximately equivalent to those of the unfilled matrix material, even though heavily filled.
摘要:
A granulating machine of substantially modular construction. The hopper-input module includes baffles to prevent flyback of the material being granulated. This module is mounted pivotally at two opposite ends to a cutting module permitting it to pivot downward or upward away from the cutting module for easy access to the cutting rotor for maintenance or cleaning, for example. The cutting module includes a rotor of essentially tubular construction on which rotor-knives are mounted. The rotor itself is mounted on a base or frame to which multi-edged, stationary bed-knives are mounted without using bolts or screws. The multiedged knives are capable of reorientation as the cutting edges become successively dulled. There is also a screen-mount module pivotally secured to the cutting module which includes a bendfree screen held in a cradle and clamped at two opposite ends by pressure elements bearing on it. The pivoting screen cradle permits access to the screen from above and to the under side of the rotor from below. Other features are described below.

A METHOD AND APPARATUS FOR EFFECTING EFFICIENT MASS CONTACT BETWEEN TWO MEDIA OF DIFFERENT DENSITIES IS DISCLOSED. THE ONE OF SAID MEDIA THAT IS OF LESSER DENSITY IS CAUSED TO OBTAIN A VORTICAL FLOW PATTERN BY MEANS OF A CIRCULAR VANED CHAMBER. THE SECOND MEDIUM, THE ONE HAVING THE GREATER DENSITY, IS ENTRAINED IN SAID FLOW PATTERN IN PARTICULATE FORM, AND IS THEREBY CAUSED TO FORM A DENSE CLOUD OF PARTICLES WITHIN SAID VORTICAL FLOW. AN UPPER LIMIT ON PARTICLE SIZE WITHIN THE CLOUD IS ESTABLISHED BY THE DIAMETER OF THE CHAMBER, AND BY AN APERTURED WALL CONSTRUCTION THEREFOR, WHEREBY OVERSIZE PARTICLES ARE CAUSED TO MIGRATE OUTWARDLY FROM THE CHAMBER UNDER THE INFLUENCE OF CENTRIFUGAL FORCE.
摘要:
Apparatus for scrubbing a gas in which a vortical flow of a gas and liquid mixture created by an entrainer is introduced into a de-entrainer through a guide/deflector assembly. Particulate is removed from the gas and picked up by the liquid during entrainment. De-entrainment separates the liquid from the gas and delivers the scrubbed gas to an outlet. A conical top provided upon the primary de-entrainer prevents water droplets, which also contain particulate from being re-entrained with the scrubbed gas and further serves to deflect the droplet toward the sides of the de-entrainer where they may be collected, filtered and returned to the entrainer, thereby significantly increasing contaminant removal from the gas stream. Anti-spin plates are provides at spaced angular interval just upstream of the scrubbed gas outlet which break the vortex of air formed by the primary de-entrainer which serves to remove additional droplets and water vapor by mechanical condensation and agglomeration increasing efficiency of contaminant removal and further reducing the pressure drop required to move air out of the scrubber and into the atmosphere. The reduced pressure drop makes more effective use of the pressure in the dirty gas region thus further improving efficiency.
