Abstract: Abstract Ammonia Production Process In an ammonia production process a hydrocarbon steam mixture is preheated and reacted in an adiabatic catalyst bed,  The resulting methane-containing gas is reacted with air to introduce more than 1 N2 per 3H2 and purified.  The purified gas is passed to ammonia synthesis in admixture with a hydrogen-rich stream and separated from reacted synthesis gas wherein the rate of flow of that stream is controlled so that the H2:N2 ratio of the gas entering the synthesis catalyst is in the range 1.0 to 2.5.  Preferably methane is purged to the extent of 5 - 15% of the hydrocarbon feedstock.

Abstract: ELECTRONIC TONE RINGER                       ABSTRACT OF THE DISCLOSURE An electronic tone ringer for use in a telephone instrument to respond to ringing currents to generate an output tone electronically is described. A controlled breakdown rectifier bridge is placed across the input line to produce a d.c. output in response to ring input. The d.c. output is fed to an oscillator to produce a signal which is fed to a piezo-electric transducer to produce output tones. A number of safeguards are built into the circuit to prevent random noises from being fed to the oscillator. Further, the controlled breakdown bridge provides voltage clamp action to prevent spikes of voltage from damaging the circuit.

Abstract: A B S T R A C T     Transverse reduction cells for producing aluminum and con-nected in series are such that the direct electric current leaves the cathode bar ends of one cell and passes to the long side of the anode beam of the next cell via so-called risers.     Cells (18) in need of repair are replaced in that first the riser conductor bars (22) are bridged over using a short circuiting device, separated and disconnected along with all other supply lines.     With the help of at least four rollers (56,58,62) on the steel shell, the electrolytic cell (18) can be removed from the row of cells without changing level, loaded onto a low level transporter (34) which can run the full length of the pot room, and moved to the cell repair shop (46).     Concrete foundation slabs (12,44,50) can be cast on the levelled ground of the pot room. Only a relatively small amount of the floor need be dug up for the somewhat lower concrete slab flooring (14) for the transporter (34). I-beam sections (16) are embedded in the upper concrete slabs (12, 44,50) and such that their running surface (38) is at the same level (36) as the cell transporter (34).

Abstract: ABSTRACT OF THE DISCLOSURE A rapidly turnable laser wherein the optical reso-nating cavity is defined by a partially reflecting plane mirror and a rotating faceted polygonal solid.  A Brewster window is adapted to sequentially select and direct one and only one of the wavelengths of light from the beam emitted by the lasers amplifying medium along a path back through the lasers amplify-ing medium as the faceted polygonal solid is continuously rotated.  One embodiment of the present invention forms the rotating reflecting  solid as having at least one face thereof being a Littrow reflective grating.  A pulsed laser is adapted to tune to a different wavelength of light each time some or all of the grating faces of the polygonal solid are rotated to intercept the longitudinal axis of the laser.  A second embodiment forms the rotating reflecting solid which reflects laser light to a single stationary Littrow grating.  A third embodiment produces pairs of output pulses where the pair mem-bers are separated by a short time interval.

Abstract: APPARATUS FOR FAILURE PREDICTION OF EARTH STRUCTURES                 Abstract of the Disclosure Apparatus is disclosed for failure prediction of earth structures.  The apparatus is intrinsically safe with all necessary electronics contained in a portable central unit except for a sensor and a preamplifier which are positioned contiguous to an earth structure to be monitored and are connected through an electrical cable to the central unit.          The entire apparatus is powered by a six volt battery power source also contained in the central unit with electrical isolation being featured.  The apparatus monitors the sel-ected earth structure and predicts failure through analysis of determined microseismic emissions arising from changes in mechanical loading of the selected earth structure.  In the central unit, microseismic emissions from the sensor and preamplifier are continuously received, conditioned and then utilized to form event and energy counts which are supplied to a computer that is controlled in such a manner so as to analyze the incoming data and determine therefrom imminent failure of the monitored earth structure with such detected failure being automatically immediately indicated.          The apparatus is particularly useful in hazardous environments and in close proximity to personnel whose safey depends upon the relative stability of the earth structure, and is therefore particularly useful in underground mines to predict earth structure failures such as roof falls.
