Abstract: ABSTRACT OF THE DISCLOSURE         A method of obtaining an NMR spectrum for at least a portion of a specimen slice is provided.  The method comprises acquiring a number of projections of the specimen slice and shifting the projections by .DELTA. f for any point of interest.  The shifted projections are then summed or com-pared to produce a resultant point spectrum.  Preferably, shifted projections in each of a plurality of selected sets thereof are compared so as to produce a plurality of re-sultant spectra for the point which are used to produce a first iterated point spectrum.  Additional stages of ite-ration are provided to minimize the effect of artifacts which comprises comparing aligned corresponding positions on an i iterated spectrum with a previously uncompared re-sultant point spectrum, so as to produce an i + 1 iterated spectrum for the point, and repeating the foregoing a plu-rality of times, in each case using the iterated spectrum from the previous iteration as the i iterated spectrum.

Abstract: ABSTRACT OF THE DISCLOSURE            A delayed coking process is conducted at a relatively low temperature with the introduction of a gas into the coking drum during the coking reaction to strip volatile matter from the coke product and to form coke containing 6 to 12 weight percent volatile matter. Low temperature delayed coking decreases the amount of coke yield, calculated on a volatile-free basis, and increases liquid yield.

Abstract: UNIVERSAL DANCER SPEED CONTROL       ABSTRACT          A speed control device for a web processing machine having a dancer arm on its input.  A cable connected to the dancer arm translates its movement to a cable reel of a speed control potentiometer actuator mechanism which has a variable rotary lost motion connecting device to furnish a dead band so the potentiometer does not immediately respond to every movement of the dancer arm.          The cable is secured to the arm at a short distance from the arm pivot point so that a relatively small cable movement is involved.

Abstract: Abstract of the Disclosure A belt press is formed of a longitudinal row of upright and abutting press frames each comprising upper and lower traverses respectively having lower and upper traverse faces and two upright tie bolts extending vertically between the upper and lower traverses and securing the lower traverse to the upper traverse.  Upper and lower press platens carried on and between the traverses have respective upper and lower platen faces respectively confronting the lower and upper traverse faces.  A belt workpiece to be joined or repaired is engaged between the platens.  Respective upper and lower pressure plates engaged between the platen faces and the respective traverse faces have built-in respective upper and lower heaters.  Hydraulic actuators engaged between the upper traverse and the upper pressure plate are vertically expansible for displacing the upper pressure plate down and thereby pressing the platens against a belt engaged therebetween.  The upper pressure plate is of U-section and upwardly open with a base lying on the upper pressure plate and a pair of sides projecting upward therefrom.  The hydraulic actuators are between the pressure-plate sides and are constituted as at least one diametrally compressible but circumferentially unstretchable hydraulic hose forming a substantially closed chamber and lying between the pressure-plate sides.

Abstract: METHOD AND CIRCUIT FOR DC MOTOR FIELD REGULATION    WITH SPEED FEEDBACK     Abstract of the Disclosure A method and a circuit for motor field regulation in the constant horsepower speed range, wherein the weakening of field current allows operation of the motor at speeds higher than the base speed while maintaining rated armature voltage.  The field current is weakened in response to speed feedback signals to provide a rapid response in controlling field current.  The motor field is also regulated in response to a counter-EMF and IR compensation circuit to further weaken the field current, where the counter-EMF developed in the DC motor would cause excessive voltage across the armature.

Abstract: ABSTRACT         A semiconductor diode is designed to operate at a temperature where the thermal generation of free charge carriers is negliglble.  The diode includes a first semiconducting layer with a sufficient concentration of first conductivity type impurities to exhibit metallic type conductivity, a second semiconducting layer with a sufficient first conductivity type concentration to create an impurity energy band and with a second conduc-tivity type impurity concentration less than half the first, and a blocking layer between the first and second layers with a sufficiently low impurity concentration that substantially no charge transport can occur by an im-purity conduction mechanism.  First and second ohmic contacts are deposited on the first and second layers opposite the blocking layer.  The same types of layers are used to construct transistors.

Abstract: ABSTRACT OF THE DISCLOSURE     A tension tie member is anchored between two spaced locations on a structure, such as a diagonal cable in a stayed girder bridge.  The tie member is supported on the structure adjacent at least one anchor location by an annular bearing member encircling an outer protective casing of the tie member.          The bearing member is positioned within an annular chamber in the structure at the point where the tie member extends through the structure toward the anchor location.  The diameter of the annular chamber is larger than the diameter of the tie member so that there is a certain amount of play between the bearing member encircling the tie member and the surface of the annular chamber whereby lateral movement of the tie member can occur.          With the tie member anchored in place the space between the outside of the bearing member and the inside surface of the annular chamber can be filled with grout to support the tie member.

Abstract: Abstract of the Disclosure CRACK RESISTANT COATING FOR MASONRY STRUCTURES     Masonry structures are susceptible to cracking due to distortion caused by movement of their foundation, vibration, and/or drying out subsequent to the construction of the structure.  Such cracking often occurs after the structure has been painted.  This results in the crack being transmitted through the coating of paint.  Upon repainting of the masonry structure new cracks often develop and are transmitted through the paint coating within a short period of time.     This invention discloses a crack resistant coating for masonry structures comprising:     (1) a crack absorbing layer which is contiguous to the masonry structure which contains beads which are essentially spherical and which are bound by a resin binder, and (2) a conventional coating layer which is contiguous to and covers the crack absorbing layer.
