Abstract: ABSTRACT OF THE INVENTION     An improved method of removing gas from an underground seam, such as a coal seam, between adjacent strata, involving (1) forcing pressurized fluid into a borehole at an initial low rate and gradually increasing the rate to a final treatment rate such that a bottom borehole pressure is achieved which will selectively fracture the seam as compared to adjacent strata in a manner that produces a vertically confined fracture zone, and (2) adding proppant to the pressurized fluid being forced into said borehole in a controlled manner in order to prevent proppant flowing back into the borehole on removal of the pressurized fluid.

Abstract: Abstract of the Disclosure In the continuous catalytic polymerization of isobutylene, the exothermic heat of reaction is removed by vaporizing unreacted hydro-carbons, compressing and condensing the vaporized hydrocarbons to yield a liquid condensate at a pressure and temperature higher than that in the reaction zone, reducing the pressure on the liquid condensate to reduce its temperature to that of the reaction zone, separating any vapors thus formed and recycling the liquid condensate to the reaction zone. The process provides an energy efficient means of controlling reaction zone temperature. The process can be employed when using either a fluidized or fixed bed catalytic system.

Abstract: TITLE:  PRESSURE RELIEF WALL         ASSEMBLY     INVENTOR:  Joseph M. Minialoff ABSTRACT OF THE DISCLOSURE     A pressure relief wall assembly has a liner panel and first and second exterior panels.  A first portion or end of the liner panel is secured to one part of the frame.  A second portion or end of the liner panel is releasably fastened to another part of the frame, by a plurality of first elements, which elements  fail when an excess pressure is applied to either side of the wall assembly.  A first end or portion of the first exterior panel is secured to the one part of the frame, and a second end portion of the first exterior panel is secured to the liner panel, for example, at a location midway between the two parts of the frame.  The second exterior panel has a first portion secured to the other part of the frame.          A second, end portion of the second exterior panel is releasably fastened tothe liner panel or to the first exterior panel by a plurality of second elements, which fail when excess pressure is applied to the assembly.  In response to excess pressure, the first and second elements fail.  The liner panel and the first exterior panel deflect, whilst remaining attached to the one part of the frame.  The second exterior panel remains attached to the other part of the frame, but becomes detached from the other panels.  It also deflects, so that the excess pressure is released and no excessive loads are applied to the frame.

Abstract: ABSTRACT OF THE DISCLOSURE        A bland and nutritive soybean food product is  produced  by  a  process  involving  the  steps  of heating a proteinaceous soybean material with steam to  preferably  220°F  (104°C)  and  subjecting  the proteinaceous  soybean  material  to  lower  alcohol vapors.  Initially, the soybean material is placed in a  closed  vessel  and  the  alcohol  is  added  to  the soybean  material  in  a  preferred  weight  ratio  of approximately 9 pounds (4.1 kilograms) alcohol to 60 pounds (27.2 kilograms) soybean material along with a small quantity of water.   The vessel has agitators that  agitate  the  soybean  material  sufficiently  to "fluidize" the material within the vessel.  Steam is injected into the vessel and when the temperature of the   soybean  material   preferably   reaches   220°F (104°C),  the steam is stopped and the proteinaceous soybean material is kept at that temperature in the closed  vessel  for  at  least  thirty  minutes.   The vessel  is  then  vented  at  subatmospheric  pressure, removing substantially all of the alcohol  from the proteinaceous   soybean   material   along   with   the undesirable flavor constituents.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for reproducing designated information from a digitally recorded disc uses a stepping motor which moves an optical pick-up device radially across the disc to the designated location using a predetermined number of stepping pulses representing the distance of the optical head to the designated location.  A motor control circuit generates the stepping pulses in response to a driving signal comprising a predetermined number of driving pulses and a direction signal, the polarity of which corresponds to radially inward or outward movement of the pick-up device relative to the disc.  A counter counts the driving pulses so that the actual count in the counter represents the distance of the optical head from a reference location, typically the beginning of the recorded track on the disc.  A designating signal is used to generate a designated count of driving pulses required to reach the designated location from the same reference location.  The difference between the actual count and the designated count is used to provide the driving signal for moving the pick-up device.  When the pick-up device is within a certain distance of the designated location, address information read from the disc by the optical head is used to provide a fine-adjustment signal to precisely locate the optical head.

Abstract: Abstract:    In a distributed processing system having a plurality of interconnected subsystems of equal level, each subsystem operates to diagnose faults in other subsystems and protects its own subsystem based on the diagnosis of the faults of the other subsystems.  The subsystems may be network control processors connected to common signal transmission lines, each of which carries major and minor loop check messages used to detect the faults in the other network control processors and constitutes a bypass route to protect its own unit when the fault occurs.  If a transient fault occurs in the systems, an indication of the degree of the transient fault is stored and a possibility that the transient fault will change to a permanent fault is determined based on a time variation of the degree of the fault.  If it is deter-mined that the transient fault will change to a permanent fault, it is indicated to a man-machine system.  In this manner, a loop transmission system which can be readily prediction-diagnosed for a fault is provided.  In a second embodiment, means for calculating a feedback rate of a signal sent out to the transmission line and means for calculating the degree of fault on the transmission line based on the feedback rate calculated by the calculation means are provided.

Abstract: METHODS AND COMPOSITIONS FOR DETECTING AND IMAGING A GAS IN AN ANIMAL BY NUCLEAR MAGNETIC RESONANCE     ABSTRACT OF THE DISCLOSURE      A novel and improved method to detect and/or measure indirectly at least one gas, particularly dissolved gases, of an animal employing nuclear magnetic resonance techniques (NMR).          The method examines an NMR spectrum to determine chemical shift relaxation times or spin-spin couplings for an element of an animal influenced by at least one gas of the animal.  Uniquely, the gas detected according to the principles of this invention may be insensitive to present NMR techniques.  Further, the present invention discloses a novel method to determine and monitor gaseous physiological states of an animal.  Because of the unique and advantageous non-invasive, non-destructive and non-ionizing properties, the present invention may be employed in an animal continuously and in vivo.  Still further, the present invention provides for the imaging of at least one-, two-, or three-dimensional projections reconstructed from a chemical shift, relaxation times, or spin-spin couplings for an element of an animal influenced by at least one gas in the animal.  Novel compounds directed to providing radio-frequency reference signals in which chemical shifts may be determined therefrom are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         An AC motor such as an induction motor or a synchronous motor is driven by a PWM inverter.  Turn-on of the PWM inverter is controlled by PWM pulse signals obtained as a result of comparison between voltage command signals (a modulation signal) and a carrier wave signal.          The voltage command signals are obtained as a function of errors between current command signals and detected current signals.  Ripples included in the voltage command signals are so suppressed as to be decreased as the rotation speed of the AC motor becomes lower.  By so suppressing the ripples, the level of noise generated from the motor can be reduced especially when the motor operates in a low-speed rotation range.
