Abstract: ABSTRACT OF THE DISCLOSURE      "COMPUTER-CONTROLLED, PORTABLE PULSED NMR INSTRUMENT AND METHOD OF USE WHEREIN A DC MAGNETIC FIELD GRADIENT             IS ARTIFICIALLY INTRODUCED"          In accordance with the present invention, fluid-flow properties of a rock sample based on NMR response of the hydrogen nuclei of interstitial fluids within the pore space of such sample, can be swiftly and accurately achieved using a computer-controlled, portable NMR instrument.  The inherent instrument inadequacy of phase background jitter is controllably augmented by generating (via 2 computer-initiated DC source current) a DC magnetic field gradient across the sample.  Result:  A DC field inhomogeneity of D gauss is discontinuously introduced to the steady DC field to maintain high data-throughput efficiency, i.e., the number of NMR responses performed per unit time.          And, even though the instrument is placed at field sited away from the usual processing center, quick analysis of rock samples as during the drilling of a well, still occurs.

Abstract: ABSTRACT OF THE DISCLOSURE           In a process for the continuous thickening of suspensions in a filter concentrator with plug-shaped filter elements, which are fixed on individually removable collect-ing tubes, without interrupting the filtration, individual collecting tubes are disconnected at determined intervals by means of quickly closing valves, and are flushed back by means of compressed air across a tube conduit and valve.          Through the pressure surge, the filter elements are freed of solids, which sink to the bottom and are periodically removed across the discharge connection.  In this manner, the filter-ing capacity can be kept constant without interrupting the filtration .

Abstract: ABSTRACT           An  improved  panel  board  construction  is  described, including an extruded insulative base pan having integral means for slidably engaging at least one main-line bus bar and a neutral con-nector  element,  each  having  a  plurality of  electrical  contact points.   The base pan also includes means for preventing current flow through the base pan between any two of the contact points of the main-line bus bars.  The prevention means includes a protrusion extending from the base pan  having a tortuously formed surface thereon.   The panel board is provided with interchangeable main-line lugs which may be used to directly contact the main-line bus bars or, alternatively, support a main-line circuit breaker between the lugs and the main-line bus bars.  The base pan is symmetrically formed by an extrusion process so that it may be adaptable for use with a variety of panel board sizes simply by shearing the base pan to form the appropriate length.

Abstract: ABSTRACT OF THE DISCLOSURE:         The invention provides a method for resolving a data packet collision in a local network where a plurality of nodes which respectively comprise proc-essors and terminal equipment utilize a single transmission line in accordance with a contention system.         A contention phase is initiated unless a collision occurs.  When a collision occurs, a resolution phase is initiated.  The nodes which have been performing transmission immediately stop transmission.  They discriminate their positions on the transmission line before a time interval (2 x maximum transmission delay time interval) elapses from the start of transmission.  If no signal is received by a given node from the left, the given node is regarded as the leftmost node among the conflicting nodes.  The leftmost node immediately starts transmitting a packet.          Other nodes except for the leftmost node stop retransmitting the packets.  The nodes which have performed retransmission are stopped until the resolution phase is completed.  The nodes except for the leftmost node receive retransmitted packets and immediately send out short reservation signals to the right.  A node which does not receive the reservation signal from any other node during the reservation signal transmission is the leftmost node among the nodes which may not perform retransmission, and performs retransmission immediately after the reservation signal is sent out.  Retransmission of the packet and transmission of the reservation signal are repeated.  When the final conflicting node finishes retransmission, all of the nodes complete transmission.          Each node continuously monitors the transmission line.          When a nonsignalling period continues for more than a given time period (2 x maximum propagating delay time interval), another contention phase is initiated.

Abstract: ABSTRACT OF THE DTSCLOSURE          Nitroarylucetic acid esters are prepared by rescting a nitroaromntic compound with an alpha,ulpha-disubstituted acetic acid ester in a sub-stantially anhydrous aprotic solvent and in the presence of a base so that the ester undergoes a nucleophilic substitution on an unsubstituted ring carbon of the nitrouromatic compound during which an alpha-substituent functions as a leaving group.

Abstract: ABSTRACT OF THE DISCLOSURE   A speed control mechanism for a hydrostatic-ally driven vehicle such as a street sweeper is dis-closed which includes a selector lever.  When the lever is in a variable engine speed position, depression of an accelerator pedal progressively opens the engine throttle from idle speed to high engine speed and progressively closes an inching valve thereby enabling the operator to comfortably drive the vehicle through stop and go traffic.  When the lever is in a governor controlled high speed position, the engine throttle is opened and the engine is driven at hush speed under control of the governor, and progressive depression of the throttle progressively closes the inching valve thereby providing optimum power while the vehicle is working, such as sweeping streets, with the speed of the vehicle being controlled by the position of the throttle and the position of the inching valve.
