Abstract: ROCKER SWITCH HAVING IMPROVED CONTACT-OPERATING MEANS           ABSTRACT OF THE DISCLOSURE          A general purpose, alternating current wall switch is provided with a rocker handle having an extremely light feel re-sulting from the fact that the angular distance or throw between the opposite extreme positions thereof is very small, on the order of about 20 degrees in a preferred embodiment.  Throw of the handle through the noted small angular distance is effective, however, to operate a contact actuator through a much larger angular distance to assure a proper mechanical and electrical function, the distance through which the contact actuator rocks in a preferred embodiment being on the order of about 50 degrees.  The mechanical advantage is produced by a loose, lost motion interengagement between the rocker handle and the contact actuator, both of which are mounted to rock about spaced, separate pivot axes.  The interengagement of the rocker handle and contact actuator results from the provision of a bifurcation on the underside of the rocker handle, loosely embracing a triangular rib or projection on the contact actuator head.  Throw of the rocker handle is effective to initially produce a camming engagement of one of the fork arms of the bifurcation against an adjacent surface of the triangular rib.  As the rocker handle moves to its opposite extreme position, the contact actuator is cammed over center, and an associated spring means then becomes effective to snap the actuator the remaining distance to its opposite extreme position.  As the actuator and the rocker handle moves through the remainder of their respective angular distances following passage of the actuator over dead center, they are fully disengaged from each other and there is no interference between them.

Abstract: ABSTRACT    METHODS OF INDICATING NUCLEAR SPIN DENSITY DISTRIBUTION Spin density distribution in a sample subjected to a static magnetic field along a y-axis is determined by subjecting the sample to an initial magnetic field gradient Gz to the static field together with a 90° selective rf pulse to select a strip. The Gz gradient is then replaced by a filter gradient Gx for a limited period of time during which the free induction signal only partially decays and then immediately replacing the filter gradient by a read gradient Gy and then reading out the free induction decay signal.  The sequence may be repeated cyclically with a delay between each cycle.

Abstract: PROCESS FOR MEASURING THICKNESS OF VERY THIN          MOVING FILMS     Abstract of the Disclosure The thickness of very thin dielectric films covering metal surfaces are measured while the surface and the film are in motion.  This is accomplished by spacing a prism very close to the moving film, passing light which is polarized in the plane of incidence into said prism at various angles of incidence to generate surface plasma oscillations on the film-metal layer interface and thereby attenuating reflectivity, then measuring said reflectivity as a function of the angle of incidence, determining that angle of incidence which produces the minimum reflectivity and comparing that angle of incidence to a previously determined standard to measure the film thickness.

Abstract: Abstract A method and means for improving control of the process for directly reducing ores containing iron oxide in a rotary kiln using a solid carbonaceous reducing agent, such as coal, introduced from the ore feed and discharge ends of the kiln, as both fuel and reductant, is disclosed wherein the temperature profile of the moving bed of solids is maintained such that the temperature is moderated to remain below the sintering temperature of the materials in the bed from the feed end zone for about the first two-thirds of the kiln length and the temperature is then maximized within sintering limitations in the working zone which is limited to about the last third of the kiln length.     The temperature profile is controlled by regulating the volumes of air supplied to the kiln atmosphere from air injectors at spaced intervals along the length of the kiln, after establishing the appropriate proportion of coal stead-ily blown into the discharge end of the kiln for the par-ticular process constituents being used.

A temperature sensor with a voltage frequency converter provides an electric signal with a frequency which varies according to the tempertaure of the thermo-carrier fluid.  An electronic circuit processes the temperature signal through a variable multiplier which is set by respective multiplexed heat transfer ratings of the corresponding stations to produce a series of impulse trains corresponding to thermal energy consumed by the corresponding stations.  Multiplexed counting devices, controlled by demand signals corresponding to fluid flow in the respective stations, receive the respective pulse trains to produce readings of the thermal energy consumed by the corresponding stations.
