Abstract: Aa process for preparing an irreversibly dried coal which utilizes a fluidized bed reactor with a fluidized bed density of from about 20 to about 40 pounds cubic feet which is at a temperature of from about 150 to about 200 degrees Fahrenheit. To this reactor is fed coal with a moisture content of from about 25 to about 30 percent, an oxygen content of from about 10 to about 20 percent, and a volatile matter content of from about 35 to about 45 percent; and it is subjected to a temperature of from about 150 to about 200 degrees Fahrenheit for from about 1 to about 5 minutes while simultaneously being comminuted and dewatered. The comminuted and dewatered coal is passed to a second fluidized bed reactor with a fluidized bed density of from about 20 to about 40 pounds per cubic foot and a reactor temperature of from about 480 to about 600 degrees Fahrenheit. Also fed to this second fluidized bed reactor is from about 0.5 to about 3.0 weight percent of mineral oil.

Abstract: A process for preparing an irreversibly dried coal in which coal with a moisture content of from about 5 to about 30 percent and a combined oxygen content of from about 10 to about 20 percent, and mineral oil with an initial boiling point of at least about 900 degrees Fahrenheit, are fed to a fluidized bed reactor with a fluidized bed density of from about 10 to about 40 pounds per cubic foot. The coal becomes coated with the mineral oil, and the coated coal is maintained within the fluidized bed at a temperature of from about 225 to about 500 degrees Fahrenheit for from about 1 to about 5 minutes while simultaneously comminuting and dewatering the coated coal.

Abstract: A bullet-proof fabric containing a first layer of high-strength fabric, a first layer of ceramic material below the first layer of high-strength fabric, and a second layer of high-strength fabric disposed below the first layer of ceramic material. The first layer ceramic material contains a multiplicity of ceramic structures, each of which has a first orifice extending through it, and a means for fastening the ceramic structure disposed within the orifice.

Abstract: A brake beam assembly containing a compression member, a tension member, a strut connected to the tension member and the compression member, and two brake heads with recesses. The ends of the compression member and the tension member are disposed within the recesses of the brake heads together with two fasteners per recess; each of the fasteners is substantially perpendicular to the tension and compression members; and no other structural elements are present in the recesses.

Abstract: A device for enclosing the back of a motor vehicle which is comprised of a flexible cover removably attached to a ridge extending from the back of the motor vehicle. When the device is attached to the motor vehicle, it encloses the space behind the back section of such vehicle, and the device forms a substantially water-proof enclosure together with the vehicle.

Abstract: A process for insertional mutagenesis and genome manipulations of yeast cells. In the first step of this process, viable yeast cells are combined with a restriction enzyme cleaved deoxyribonucleic acid fragment which lacks substantial sequence identity and shows no specific hybridization signals with the DNA of the viable yeast cells. The viable yeast cells are then transformed so that the cleaved deoxyribonucleic acid fragment is incorporated into the yeast cells by nonhomologous recombination; and the transformed yeast cells are then incubated in the presence of a growth medium.

Abstract: A garment which contains about 50 weight percent of cotton and a strip of tire rubber is durably affixed to at least one part of the garment. The strip of tire rubber has a length of at least about 20 inches, a width of from about 8 to about 14 inches, and an aspect ratio of at least about 2.5/1.

Abstract: A rotary device containing a housing with a curved inner surface in the shape of a trochoid and an interior wall, an eccentric mounted on a shaft disposed within the housing, a rotor mounted on the eccentric shaft and several pins attached to the rotor and extending from the rotor to the interior wall of the housing. A continuously arcuate track is disposed within the interior wall of the housing, and the pins are disposed within the track.

Abstract: A process for accurately and automatically measuring the properties of wheelset profiles while the wheelsets are in normal operation. In the first step of the process, the wheelset is rotated at a speed of at least 400 revolutions per minute while moved at a speed of at least 45 miles per hour, and a laser detection system is used to measure the profile of both wheels of the wheelset. In the second step of the process, the wheelset is rotated at a speed of less than 75 revolutions per minute while moved at a speed of less 6 miles per hour while its wheel profile properties are evaluated by a laser detection system.

Abstract: A process is described for the screening of an agent to determine its effect on the frequency of genome rearrangement in mammals. In particular, mice harboring a p.sup.un mutation are exposed to an agent of interest and the frequency of genome rearrangement relative to that observed in an unexposed mouse is determined. The relative frequency of rearrangement represents a measure of the effect of the agent on the host animal.

Abstract: A pad comprised of three leaves, each of which preferably has a numerical indicia displayed on each side of it. Each leaf is joined to two other leaves by means of a first segment of adhesive tape and a second segment of adhesive tape. The end portions of each of such tape segments are contiguous with one of said leaves, but the middle portions of the tape segments are not contiguous with such leaves.

Abstract: An arcuate building structure containing at least three five-sided building blocks, at least three six-sided building blocks, and said five-sided and six-sided building blocks are independently able to provide means for connecting one of said five-sided building blocks to at least one of said six-sided building blocks. The top side of the six-sided block has a substantially triangular shape, and is substantially parallel to the bottom side of the six-sided block. The front side of the six-sided block has a substantially trapezoidal shape with a top edge, a bottom edge, a right edge, and a left edge. The right edge and the left edge have equal lengths and form equal angles with the bottom edge. The back side of the six-sided block has a substantially triangular shape with at least two sides equal in length to each other.
