Abstract: SIMULTANEOUS THERMAL NEUTRON DECAY TIME AND SHALE COMPENSATED CHLORINE LOG SYSTEM                 D#73,880-F           ABSTRACT OF THE DISCLOSURE:         Earth formations surrounding a well borehole are repetitively bombarded with bursts of high energy neutrons.          A radiation detector in a sonde in the borehole senses the gamma rays induced by the capture of thermal neutrons and sends representative signals to the surface.  At the surface electronics, the population of thermal neutron capture gamma rays at two separate and distinct times is measured.  The macroscopic thermal neutron capture cross section of the formation may be thus determined and logged.  Further, two additional single channel energy analyzers, such as from 1.30 to 2.92 Mev and from 3.43 to 10.0 Mev, sense formation capture gamma ray response over a common time interval following each neutron burst.  The measurements made in these two additional single channel analyzers are used to distinguish between the presence of salt water and hydrocar-bons in the formation, which is also logged.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is an arrangement for changing a pouring tube on the pouring nozzle of a metallurgical vessel, particularly on the sliding gate nozzle of a tundish in a continuous casting plant, comprising at least two pouring tube holders which can be alternately moved underneath the nozzle, attached thereto and removed again.  The pouring tube holders are provided at the ends of swivel arms which are located by stop means in correct position for attaching the pouring tube and adapted to swing about a pivot axis parallel to the nozzle axis.  The pouring tube holders and/or their swivel arms are provided with displacing means for moving them in the required direction for attaching the pouring tube.  In such an arrangement only the end of the swivel arm which is in the operative position extends into the critical region between the tundish and the mould and all other parts of the arrangement are outside the direct range of the heat radiated during the pour. The arrangement can therefore be safely and satisfactorily operated.  Further-more, the region where casting proceeds remains substantially free from major obstructions so that clear observation is possible.  Apart from this, the starting position from which the pouring tube is applied to the nozzle assembly is automatically reached and the pouring tube can then be tightened by the displacing means without loss of time. Conveniently the swivel arms may be mounted ore above the other on a common pivot pin and the free end of each arm may contain a carrier for an axially movable holder which holds the pouring tube so that it cannot rotate, the carriers being horizontally coplanar by reason of one or both swivel arms being formed with a suitable vertical offset.  This arrangement is not only of simple design but it also ensures that the pouring tube will always be correctly positioned in relation to the mould.

Abstract: SYNONYM CONTROL MEANS FOR MULTIPLE VIRTUAL             STORAGE SYSTEMS                       ABSTRACT The embodiments relate to special controls in a processor which eliminate synonym entries in a translation lookaside buffer (DLAT) and their corresponding page duplication in main storage for a system which has DLAT entries that can concurrently translate virtual addresses in multiple address spaces into real main storage addresses.  The controls provide a common space bit in any segment table entry (STE) or alternatively in any page table entry (PTE) in any private address space to indicate whether the segment or page, respectively, contains programs and data private to the address space or shared by all address spaces.  Each DLAT entry contains a common/private storage indicator which is set to the state of the common space bit in the STE or PTE used in an address translation loaded into the DLAT entry.          When the entry is read, the private/common storage indicator controls whether the DLAT can only be used by the address space identified in the DLAT, or by all address spaces.

Abstract: RAIL HOUSE CAR DOOR CRANK MOUNT               Abstract of the Disclosure A rail house car with at least one opening along each of its sides.  The car includes a door for closing each of the openings by movement of the doors longitudinally along the car sides and laterally into and out of the openings.  Bottom and top rotating crank members moveably support and retain the doors on longitudinal tracks below the doors and within longitudinal retainer means above the doors.  At least some of the crank members are selectively manually driven by rotational means for selective lateral movement of the doors.  The top crank members adjacent the upper portion of the doors each include a bore.  A forged pin is telescopingly received in each of a plurality of pipes rotationally mounted on the door.  Each pin has a shank portion and an upper headed or flanged portion.  Each crank member's bore is counterbored to receive the headed portion of a pin.  Substantially the entire periphery of the shank portion is welded to its associated crank member and only a portion of the flange formed by the head of the pin is welded to the crank member counterbore.  This minimizes deterioration of the strength given to the pin flange by the forging operation.  Alternatively, the head can be spaced from the top of the crank member and only the shank portion welded to it.  The crank mount is also for use with any auxiliary crank members which are in engagement with the longitudinal retaining means of the car. A pin or weld or both can secure the extension pin and pipe to prevent relative rotation therebetween.

Abstract: ABSTRACT OF THE DISCLOSURE   A resistor, a DC source and a current converter are connected in series between one terminal of the field winding and the ground.  When a ground fault occurs on the field winding, it is detected by the output of a voltage detector connected across the resistor or the output of the current converter, and an alarm device is operated.  At the same time, another re-sistor is connected between the other terminal of the field winding and the current converter through a switch, and the magnitude of the ground fault IS calculated by the outputs of the voltage detector and of the current converter before and after closure of the switch.  According to this invention the operation of the generator is continued when the fault is light but the generator is immediately disconnected from the power system when the fault is severe thus decreasing the disturbance of the power system in case of a light fault but positively protecting the generator against heavy fault.
