Abstract: ABSTRACT        Methanol is produced from a carbon monoxide stream by reacting carbon monoxide with steam in a catalytic shift reaction, removing any excess steam and at least part of the carbon dioxide from the shifted gas, reacting the resulting gas over a copper-containing methanol synthesis catalyst at under 300°C, heat exchanging reacted synthesis gas with water under pressure and bringing the resulting hot water into direct heat exchange with the carbon monoxide stream to provide steam for the shift reaction.  In a preferred process the carbon monoxide stream is freed of non-refractory sulphur compounds before the shift stage and the refractory sulphur compounds are converted in the shift stage to H2S, which is removed with the carbon dioxide,

The roll elements positioned in a pyramid roll assembly are dynamically adjustable toward and away from each other to provide different size line pipe, or similar tubular articles.  The segments of the roll elements are mounted on cantilever arms, the leading edge of blank being deflected against the upper curved surface of the arms during the final stages of forming.  The deflection is maintained within the elastic recovery limit of the metal.  A rigid frame mounts the cantilever arm and other components.  The frame includes a plurality of vertical bed plates and corresponding upper frame plates and cross tie members.  A pusher mechanism pushes the sheet blank through the pyramid roll assembly.  A multi-walled tube may be formed by providing the required additional length to the blank and continuation of the forming beyond 360°.  The blank is confined between idler rollers on the frame structures during forming.  Special roller handling assemblies are provided for loading the blank and for unloading the finished tube from the machine.

Abstract: KEY MECHANISM HAVING A SNAP ACTION     ABSTRACT OF THE DISCLOSURE     A key mechanism arrangement for use in a keyboard of a business machine wherein a snap motion occurs in response to depression of a keylever.  An elongated resilient member is pivotally supported intermediate its ends on a member.  One end of the resilient member is coupled to the keylever for bias support thereof, while the free end cooperates with a restraining means, to first prevent its movement during initial keylever depression to store energy and then quickly released, causing the free end to snap against a member of a utilization apparatus.  The resilient member restores the key mechanism arrangement to a rest position upon release of the keylever.  Four embodiments are disclosed all having the same mode of operation.  In three of the embodiments the restraining means includes a means of latching the free end of the resilient member and then selectively releasing that end actuated by further depression of the keylever.  In the fourth embodiment the free end of the resilient member is held by a magnet until the accumulation of energy is sufficient to overcome the magnetic force.  Structure is provided on the keylever for uniquely coupling one end of the resilient member to the keylever for movement there with.

Abstract: ABSTRACT OF THE DISCLOSURE           A system is disclosed in which a differential phase-shift keyed, pulse-code-modulated transmission is itself delta-modulated in order to derive a transmission clock signal characteristic of -the transmission, as opposed to being characteristic of an underlying data signal which is used as a modulating waveform in the transmission.  The delta-modulation detects changes in state of the data trans-mission, which changes in state can be monitored in order to derive the transmission clock signal utilized.  In a preferred embodiment, a phase-locked loop may be utilized to produce a pulse train having the same frequency as, and being in phase with, such changes of state in the transmission.

Abstract: Abstract of the Disclosure The present invention provides a new and improved method of making an improved turbine engine component having an annular array of airfoils connected with inner and outer shrouds.  The airfoils are cast separately from the shrouds to enable the airfoils and shrouds to be made from either the same or different materials.  The airfoils advantageously have an elongated columnar grain structure with grain boundaries extending parallel to the leading and trailing edges of the airfoils.  The inner and outer shrouds are formed of a plurality of arcuate sections which also may have an elongated columnar grain structure.  The ends of the arcuate shroud sections are interconnected in such an orientation that the grain boundaries extend circumferentially around the circular shrouds to minimize the extent to which ends of the grains are exposes.  In another embodiment of the invention, each of the arcuate shroud sections is formed of a single crystal.  In accordance with a feature of the invention, the forming of a shroud segment which includes a pair of arcuate shroud sections and one or more airfoils is facilitates by using a spacer bar.  The spacer bar holds the shroud sections in a fixed spatial relationship relative to each other while airfoils are connected with the shroud sections.  Once the airfoils have been connected with the shroud sections, the spacer bar is removed.

Abstract: IMPROVED SPOT ARREST SYSTEM                 ABSTRACT OF THE DISCLOSURE           A spot arrest system modulates cathode ray tube beam scanning speed in accordance with compressed and noise-processed image enhancement signals derived from video signal transitions.  A generator provides first derivative type image enhancement signals which are com-pressed by a log amplifier. The log amplifier tends to equalize the amplitude of the image enhancement signals for various video transitions at an optimum amplitude. The signals are then applied to a noise processor which attenuates image enhancement signals which do not corre-late to first derivatives of the corresponding video signals.  In the noise processor, a multiplier receives as one input the compressed image enhancement signals and receives as another input control signals based on first derivatives of the video signals.  The noise-processed signals are then coupled to the cathode ray tube to mod-ulate the beam scan speed.  Additionally, beam current may be modulated inversely with respect to the beam scan speed modulation.
