Abstract: ABSTRACT OF THE DISCLOSURE     A pump such as a vehicle air conditioner compressor has a compressor shaft, a continuously engine-driven flywheel and means such as an electromagnetic clutch for selectively coup-ling the flywheel to the shaft to operate the pump.  The fly-wheel also provides a permanent magnet field which field rot-ates with the flywheel and induces in the windings of a rela-tively stationary annular stator assembly an electric voltage in response to the rotating magnetic field.  The pump shaft, annular clutch actuating coil, annular stator assembly and permanent magnet flywheel are all generally concentrically disposed and in the order stated.   The flywheel is driven any time that the engine is running thereby inducing a volt-age in the stator windings and that flywheel also drives the exemplary compressor when the clutch is actuated.

Abstract: Abstract Ammonia production process and plant An ammonia production process comprises steam hydrocarbon primary reforming, air secondary reforming, carbon monoxide shift, carbon oxides removal, ammonia synthesis and discarding of non-reactive gases and is made more economical in energy consumption by using excess air in secondary reforming and treating the synthesis gas to separate a hydrogen-enriched stream and returning that stream to the synthesis.   Preferably the synthesis gas after carbon oxides removal is compressed if at all by no more than 50% and consequently the process can be carried out in a plant having a gas circulator but no compressor.          Preferably synthesis is at a pressure in the range 40-80 bar abs. and at an outlet temperature in the range 350-430°C over a catalyst containing iron, cobalt and promoting compounds.   Recovery of the hydrogen-enriched stream is preferably from a side stream of synthesis gas.

Abstract: 315,727 Abstract The electric Spanish guitar incorporates a unitary nut element which has a plurality of edges offset from each other, the offsets being such that each string bends sharply at two places before being secured to a tuning screw.  Such edges for each string are at the ends of a passage through which the string passes.  The axis of each passage is inclined relative to the axis of the guitar neck, thus producing the indicated offset.  The inclination of each passage is such that each bend is through an angle in excess of 10 degrees and preferably in excess of 15 degrees.

Abstract: ABSTRACT:              A method and apparatus for controlling the position of write-read heads with which information is recorded in a plurality of parallel tracks on a record carrier.  In accordance with the invention a tracking sig-nal is recorded in at least selected tracks during a first time interval.  When the next track is written the supply of write signals to the write-read heads is interrupted for a second time interval, the first and second time intervals being selected in such a way that the track por-tions corresponding to said two time intervals adjoin each other.  During the second time interval the cross-talk signal produced in the write-read head by the recorded tracking signal is measured and employed to produce a con-trol signal for positioning the write-read heads.

Abstract: Abstract of the Disclosure Circuitry for driving stepping motor coils through a sequence of discrete steps, each winding of the stepping motor having drive circuitry which includes a first, low power circuit, having a regulated power supply, for supplying a substantially constant voltage and a second, high power circuit having a transistor emitter follower, the substantially constant voltage being supplied to the base thereof.  The second circuit can use a substantially un-regulated power supply, the voltage of which may vary considerably.  Such second circuit, however, supplies a substantially constant current pulse to its associated stepping motor winding even if the unregulated power supply voltage varies over a relatively wide range.  The same circuitry configuration is used for each winding so that the current pulses supplied to each winding are sub-stantially the same even if the winding resistances differ from winding to winding.  Such circuitry is extremely effective when used for positioning the read/write heads of a disk storage device in a data processing system wherein rapid and accurate positioning of such heads relative to the disk surface is required.  The heads can be controlled to move in a manner which permits them to be stopped at a desired position substantially at zero velocity so that little or no oscillation thereof occurs.
