Abstract: ABSTRACT       A film thickness detector system has first and second thickness detector positions.  The first position includes a light source for projecting a light beam to a light detector. A guide roller positions a film strip such that the light beam is tangent to a portion of the film strip supported by the guide roller.  The film strip lies between the light source and light detector and the light beam is intercepted by a portion of the film strip at an angle with respect to the longitudinal axis of the film strip.  As the thickness of the film strip intercepting a portion of the light beam varies, the output from the light detector varies in a corres-ponding manner.  The output is amplified and may be used for stopping motion of the film.  The second thickness detector position also has a light source and at least one light de-tector positioned to receive a light beam from the light source.  A sensing member is positioned to ride on a surface of the film strip and an opaque member connected to the sensing member is provided having an edge portion which inter-cepts a portion of the light beam such that variations in film thickness correspond to variations in the light detector output   Such variations are then amplified and may be em-ployed to stop the film.

Abstract: TOMOGRAPHIC APPARATUS            Abstract of the Disclosure The invention relates to the apparatus and method for constructing a representation of the variation of attenuation of penetrating radiation in a planar slice of a patient positioned in a scan circle.  The patient is irradiated with a fan shaped swath of radiation which is rotated about the patient for 180° plus approximately the angle of the fan. Radiation passing through the scan circle is converted to sets of data, each set representing a radiation attenuation across a fan.  The sets of data are filtered with a window function to remove data from some of the sets which represent radiation passing through a point in the scan circle by more than 180° relative to radiation paths through the same point.  The sets of data are serially convolved and back-projected into an image memory for display on a video monitor.  The back projector addresses each set of data by generating subsequent addresses from the previous address and the incremental displacement between adjacent pixels of the image memory using pixel driven algorithms.

Abstract: ABSTRACT            The invention relates to a four-port thermally re-sponsive valve for valving two normally closed fluid ports and one pair of normally open fluid ports in response to predetermine temperatures.  A single valve member is movably contained within a housing passageway and spring biased in a first position so that a sealing surface at each end of the valve member is re-spectively engageable with and spaced from corresponding seating surfaces in the passageway for achieving initially open or closed valved conditions between the individual ports in each pair.  A centrally located seal ring mounted in the housing passageway and surrounding the valve member isolates one pair of fluid ports from a second pair of fluid ports when the valve member is moved to a second position thereby permitting three valving functions to be attained with one device.  When pre-determined temperatures are encountered, a thermally responsive actuator connected to the valve member by a rod overcomes the biasing force generated by the spring and moves the valve member to the second position, valving substantially simultaneously each; pair of fluid ports.

Abstract: ABSTRACT OF THE DISCLOSURE            In the exemplary embodiments of the invention dis-closed, the decay of the thermal neutron concentration in an earth formation following irradiation thereof with a burst of fast neutrons is measured by detecting indications of the thermal neutron concentration during a sequence of contiguous, discrete time gates between neutron bursts. The time gate sequence begins following a discrete time delay after the commencement of the preceding neutron burst and extends over the entire, or substantially the entire, remainder of the interval between neutron bursts.   The time gates are grouped into a number of gate groups, e.g. four, each of which includes a number, e.g. four, of discrete time gates.  Both the time gates within each group and the groups themselves are contiguous in time.  The durations of the individual discrete time gates within the separate groups are equal but the duration of the time gates progressively increases from group to group in the sequence.  The duration of the neutron bursts, the duration of time delay between the end of the bursts and the beginning of the gating sequence, and the durations of the individual time gates may all be adjusted by a common, selected one of a finite number, e.g. four, of scale factor values.  Selection of the particular scale factor value used in the measurement of a given formation is made in a manner to optimize the statistical precision of the measurement of thermal neutron decay constants, e.g.? and .SIGMA., of the formation.

Abstract: ABSTRACT OF THE DISCLOSURE     Separate torque converters are selectively clutched to the hoist and drag drums of a dragline machine with a selectively engageable clutch providing a power interlock of the output of both torque converters to either one of the drums as desired.  The application and control of torque from the two torque converters to tile hoist drum is in parallel and to the drag drum is in series progressive, i.e., the drag converter being engaged first and going from zero to maximum while the hoist converter goes from zero to about fifty percent of capacity as the drag converter reaches maximum.  The reserve torque in the hoist converter may be selectively applied to the hoist drum to step the drag bucket up if the drag drum approaches a stall condition.  The hoist converter may also be selectively engaged to apply a predetermined hold back force during bucket lowering.  Another clutch may be engaged to interlock the two drums together for joint operation by the hoist converter. Thus, dragline holdback during hoisting may be achieved by the drag drum brakes, the drag drum converter or the drum interlock thereby providing the operator with considerable flexibility in controlling the path of the drag bucket during hoisting.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for the direct production of steel from particulate iron oxides or concentrates including two major steps in which in Step (1) the iron oxides are converted to iron carbide and in Step (2) steel is produced directly from the carbide in the basic oxygen furnace or the electric furnace.          In the production of the carbide the oxides are reduced and carburized in a single operation using a mixture of hydrogen as a reducing agent and carbon bearing substances such as propane primarily as carburizing agents.  Iron carbide thus produced is introduced as all or part of the charge into a basic oxygen furnace to produce steel directly without the blast furnace step.  In order to make the steel making process auto-thermal, heat is supplied either by using the hot iron carbide from Step (1) or preheating the iron carbide or by including sufficient fuel in the iron carbide to supply the required heat by combustion.
