Abstract: ABSTRACT    A process is disclosed for the separation of carbon dioxide and sulfide gases from oil shale retort off-gases, coal gasification off-gases, oxygen fire-flooding or carbon dioxide miscible flood enhanced oil recovery off-gases for recycle to a retort, gasifier or petroleum reservoir or alternately delivery to another process.  The process separates the off-gases into an essentially sulfur-free fuel gas and an acid gas for recycle to such a retort, gasifier or reservoir wherein the off-gas is compressed if necessary and cooled to separate the two streams, the acid gas is expanded in an auto refrigeration step to provide the necessary process refrigeration and the acid gas is then recycled to such a retort, gasifier or reservoir.  In the oil shale retorting and coal gasification applications, the gas' sulfur constituents are sorbed on spent oil shale particles or coal ash.

Abstract: Abstract of the Disclosure A frame synchronizing signal insertion system at a transmitting end has a plurality of multiplexers.         Frequency-divided frame synchronizing signals are produced by frame pattern generators of the plurality of multiplexers, respectively.  These frequency-divided frame synchronizing signals which have different patterns are logic-ORed by a multiplex gate so as to obtain a composite frame pattern.   When a composite multiplex signal having the composite frame pattern is transmitted to a receiving end and the composite frame pattern does not match a predetermined pattern, the receiving end can detect a malfunction of any one of the multiplexers at the transmitting end, and transmits an alarm signal or the like to indicate malfunctioning of the corresponding multiplexer.

Abstract: ABSTRACT OF THE DISCLOSURE    A Hall effect element, incorporated into an integrated circuit unit with temperature compensation, voltage regula-tion, and amplification, is mounted on top of a permanent magnet made of ceramic material with the critical Hall axis aligned with the magnet pole axis.  To avoid saturating the Hall cell, it is positioned within a pole-to-pole hole in the magnet, which creates a flux null space.  The permanent magnet and Hall cell assembly is mounted on the rail a pre-determined distance below the top so that the flange of passing wheels occupies the air gap between the magnet and the rail through which the major portion of the magnet flux flows.  Reduction of the air gap increases the level of the magnet flux and thus the level of voltage output of the Hall cell.  The output of the Hall cell is applied to a Schmitt trigger whose switching level is set by a threshold voltage unit.  Increased Hall output voltage actuates the trigger circuit which applies the signal to a switching transistor whose output in turn is applied to a pulse detector which registers the wheel detection.  The magnet, Hall circuit element, and processing network are encapsulated within an epoxy material which is fitted for direct mounting to the base of the track rail on the gauge side.

The niobium precipitations are dissolved thereby and during subsequent cooling during deformation precipitated mainly as strength-enhancing niobium oarbide.   A coarsening of the titanium nitride precipitations that takes place during this heating has not proved to be detrimental. Deformation amounts to at least 55%. This is followed by thermomechanical rolling at a temperature of at most 850 deg.C, and finish rolling at a temperature above 650 deg.C. lntensified cooling at temperatures of between 550 and 500 deg.C can follow.     :

Abstract: WEB SPLICING APPARATUS     ABSTRACT OF THE DISCLOSURE     A splicing head for an automatic zero-speed web splicing machine is disclosed in which the end of a new roll of web material can be prepared for splicing directly on resilient nip rollers which are used by the machine to perform the splicing operation.  In particular, the splicing head includes a knife carriage through which the web material passes and which can be moved transversly to the web travel direction under control of a cam and lever arrangement to introduce a predetermined loop of slack into the web material.    The action of the cam and lever mechanism also positions a serrated preparation blade mounted on cantilever arms in front of the nip rollers for squarely trimming the edge of the web material.  After the web material has been trimmed the preparation blade can be moved by the cam and lever arrangement to an out-of-the-way position to allow preparation of the web material and to prevent interference with the splicing machine as the web material runs through the machine after the splice has been made.
