Abstract: AXIAL FLOW ROTARY SEPARATOR        Abstract of the Disclosure In a combine harvester axial flow rotary separator, crop material is propelled in a generally spiral path as a relatively thin mat, maintained in contact with the inner wall of a cylindri-cal separator housing due to centrifugal force from the motion imparted to the mat by a rotor.  The rotor, in each of several embodiments disclosed, carries finger-like elements which inter-mittently penetrate and positively propel portions of the mat without compressing it, the finger action and motion providing the desired axial displacement as well as circumferential movement of portions of the mat without relying on additional axial index-ing aids such as guide vanes in the housing.  In one embodiment, positively driven finger wheels mounted obliquely and eccentrical-ly in a housing are so inclined that their net effect, when in greatest engagement with the crop material mat, is to index the portion of the mat engaged axially downstream.  Adjusting means are provided for controlling the rate of throughput.  In another embodiment, an axially reciprocating rotor slat carries a plurali-ty of finger elements so hinged that, as the slat reciprocates axially, the fingers engage the crop material mat only intermit-tently and propel it with a ratchet-like action.  In a further embodiment, crop-engaging finger elements of a rotor are mounted on bars, parallel to the separator housing axis, in a mechanical arrangement similar to a parallel bar-type side delivery rake, revolving bodily within the housing.  In a further embodiment, the rotor consists of an obliquely journaled finger wheel arrange-ment co-axial with the housing, combined with a drum or core eccentric to the housing axis and carrying functional elements such as threshing or separating bars which pass close to a grate as the rotor rotates.  Due to the eccentricity of drum and finger wheel, the fingers alternately effectively withdraw into and emerge from the drum and the inclination of the finger wheel, relative to the housing axis, is such as to ensure positive axial displacement of crop material in the desired direction while the fingers are extended from the housing.

Abstract: ABSTRACT     A process for producing improved cementing mixtures by adding coal materials thereto. Low carbon content coal mater-ials are crushed and screened to produce coal materials having a maximum diameter of 3/8 of an inch then exposed to a number of wetting and drying cycles, followed by a thorough leaching to remove water soluble and adhering substances therefrom, and produce therefrom a cleansed coal material. The cleansed coal materials are separated into first, second and third portions.          In a first embodiment, an improved cementing mixture is prod-uced by adding cleansed coal-material containing therein the requisite cement-making chemical ingredients, and fuel energy content sufficient to effect its own calcination, to a cement making kiln mixture in substitution for the raw material clays or shales normally used therewith. The cleansed coal material first portion so added, is made in a proportion of at least 60%  coal material to 40% non-coal material portions of the mixture. In a second embodiment the second portion being soft burned utilizing its own fuel energy source at approximately 600°F. such calcination being made prior to being added to the cement making kiln. This calcination provides a second or double cleansing of the coal materials thereby providing a double-cleansed and pre-calcined improved cement making add-itive, thus effecting a considerable saving in fuel energy consumption, more pure chemical ingredients and greatly impr-oved cement production. In a third embodiment the third portion cleansed coal material is calcined in the same manner as in the second embodiment except that the temperature of calcination is raised to from 800°F. to 2000°F. and the calcined materials are converted thereby into highly active improved pozzolanic cementing mixtures after grinding to produce fine particulate material fillers and larger sized aggregate material. Surplus heated gases are drawn off for recycling of heat and re-util-ization of chemicals therein.

Abstract: ABSTRACT           The invention relates to a small, efficient hermetic compressor for refrigeration wherein reduction in size and minimization of parts is emphasized.   The motor compressor unit is mounted within a sealed outer housing and comprises a cast crankcase, which is connected to the stator of the electrical motor by means of only three connecting screws that extend through the stator and are threadedly received in sockets in the downwardly depending legs of the crankcase. The crankshaft is pressed into the motor rotor and is journaled within the crankcase for rotation about a vertical axis. The crankcase includes a slot extending into the cylinder so that the connecting rod can be inserted laterally into the cylinder at the same time that it is slipped over the end of the crank-shaft, and the wrist pin is then inserted through the same slot, through -the piston and connecting rod t and is held in place by a spring clip.  A lubricant pickup tube is connected to the end of the crankshaft and extends downwardly into a cup-like cage, which serves as a shipping stop by limiting the lateral movement of the pickup tube and, therefore, the lateral movement of the compressor unit.
