Abstract: IMPROVED SYSTEM AND METHOD FOR WELL-LOGGING          Abstract of the Disclosure An improved system and method is provided for obtaining information related to subsurface earth formations.  Well-logging data from an input terminal is processed and stored in a memory by a first processor.  A second processor retrieves this data from the same memory, and further processes the data, which is then transferred to an output terminal device.  The first processor obtains access to memory or the input terminal for delivering or retrieving data during pulses of a first pulse train generated by a clock.  The second processor obtains access to the same memory or the output terminal for delivery or retrieval of data during pulses of a second pulse train generated by the clock.  Performance of each processor's respective functions is synchronized by storage and retrieval of messages by both processors in the common memory.

Abstract: RECIPROCATING STROKE LENGTH ADJUSTMENT DEVICE AND METHOD               ABSTRACT OF THE DISCLOSURE           The adjustment screw that regulates the stroke length of the piston that drives a diaphragm pump is rotated by means of a clutch and "diamond-back" screw structure.  By selectively engaging either of two oppositely oriented one-way clutches, one of two respective associated nuts that ordinarily rotate freely on the diamond-back screw is blocked from rotation when the screw moves longitudinally in one direction.  Thus locked, the nut compels the diamond-back screw to rotate, thereby turning the, adjustment screw with which it is connected in order to produce the desired increase in piston stroke length.

Abstract: WIDEBAND DIGITAL FREQUENCY DISCRIMINATOR      AND PHASE AND FREQUENCY DETECTOR     ABSTRACT     A wideband digital discriminator for demodulating an FM signal is disclosed.  An incoming FM signal cycles a counter through a series of sequential nonambiuous cyclical states   A timer is provided for producing a reference signal having a known relationship to the center frequency of the FM signal.  First and second latches, synchronous with the timing means, are provided for sampling and storing information about the present and immediately preceding output states of the counter.  A detector, operated synchronously with the reference signal, detects differences in magnitude and direction between the present and immediately preceding sampled states of the counter and generates an output signal when a state difference is detected.  The output signal can be digitally processed or integrated over time to provide an analog discriminator output.

Abstract: ABSTRACT OF THE DISCLOSURE       The use of an isotropic carbon block having an anisotropy of not more than 1.2 in terms of an anisotropic ratio of specific resistance as an anode in the production of fluorine by the electrolysis of an electrolyte comprising a mixed molten salt system of potassium fluoride and hydrogen fluoride has been found to be extremely useful for attaining increase in critical current density so that occurrence of the un-desirable anode effect can be effectively prevented.  With such an isotropic carbon block anode, even if the anode effect occurs, the electrolysis can be stably continued again by lowering the potential of the electrode.  Further, the incorporation of a fluoride into the isotropic carbon block anode and/or the addition of a fluoride into the electrolyte is effective for further increasing critical current density.

Abstract: ABSTRACT           In the field of security validators, slot acceptors have been known which transport paper of-fered as a valid security past a testing station. Previously known acceptors have been susceptible to defeat by mosaics, stringing, shocking, photocopy duplication, and the like.  Additionally, known ac-ceptors have operated in an analog mode, relying up-on rudimentary test functions.  The invention herein overcomes the problems of the prior art by present ing an acceptor having a note path (18) characterized by changes of direction (22,24), and which is secured at each end by means of unique gate assemblies (78, 98).  A plurality of sensors (148-152) are positioned along the note path and are controlled to take a mul-titude of data samples from the paper as it passes along the path.  The data is digitized (236) and used for solving complex transforms, the results of which are compared against results obtained from known valid securities to determine the authenticity of the paper offered.  Further, the system includes a unique anti-jamming technique of drive motor reversals, and an escrow feature which secures the paper once it has been determined to be authentic and before a vend has been made.  Yet further, there is included a novel receptacle for receipt and return of paper offered to the acceptor, and a number of variations of anti-stringing devices (112,114,118,130) which may be operatively positioned at the end of the note path.

Abstract: Abstract In a process in which a urea synthesis effluent obtained by reacting ammonia with carbon dioxide is subjected to a stripping step of bringing the urea synthesis effluent into countercurrent contact with carbon dioxide under heating to obtain an aqueous urea solution containing a small amount of ammonia and ammonium carbamate, such a process that the urea synthesis effluent is first brought into contact with a separated gas evolved in the stripping step under adiabatic condition or a little cooling is disclosed.  The use of the above process enables a reduction in size of the stripper and a recovery of the high pressure steam without keeping the ammonia to carbon dioxide molar ratio lower than that of the conventional method.
