Abstract: PLUX CONCENTRATOR FOR ELECTROMAGNETIC PULLING             Abstract of the Disclosure A flux concentrator has a pair of primary coils wrapped around a thin walled cylindrical portion of a secondary coil. The secondary coil has a conductive head at an end and the coil is slotted to generate a rapid high intensity axially acting flux at the head in response to a flow of current through the primary coils. A pulling force is generated as a result of a slow rise high amplitude current flow through one of the coils followed by a rapid rise reversed polarity current flow through the second primary coil.

Abstract: ABSTRACT OF THE DISCLOSURE         In complex system which involve a large amount of interacting electronic equipment and interconnecting cabling, the maintenance and testing required to isolate defective components or components having degraded performance become an almost continuous task. The system of this invention includes new techniques for continuous testing of components and interconnecting cabling of ouch a complex system such that deteriorating performance can be flagged thereby substantially eliminating catastrophic type system failure without at the same time requiring additional components and interconnecting cabling.  This invention is potentially suitable for operation with a data transmission system which includes a control means for converting parallel digital data from a computer to serial digital data for transmission to the using device through a single communication path where it is then converted to a form suitable for the using device. Such a data transmission system would also include means for converting data received in various forms from the using device into serial digital format for transmission to the control means where it is then converted to a form suitable for the computer.

Abstract: THROTTLED INPUT CATALYST SYSTEM     Abstract of the Disclosure Air input to a diesel engine is controlled so that less air input occurs at low loads than occurs at high loads.  This assures that the engine exhaust is kept at a relatively high temperature.  The relatively high temperature exhaust is passed to a catalytic reactor which has a catalyst therein which is only effective at such a high temperature.  In this manner pollutants in the exhaust are reduced and most particularly pollutants at low load operation of the engine are reduced.  To accomplish this flow into the engine is restricted proportional to the load of the engine.

Abstract: AUTOMATIC HEAD TRACKING SYSTEM                     ABSTRACT OF THE DISCLOSURE In an apparatus for reproducing video or other information signal recorded in a track on magnetic tape or other record medium; a magnetic head or transducer is moved along the track for reproducing the information signals recorded therein while a bi-morph leaf which supports the head receives an electrical drive signal for deflecting the head in a direction transverse to that along the track.

Abstract: BE IT KNOWN THAT GORDON B. FRENCH a citizen of the United States of America of 7684- North Quartz Street, Golden, Colorado 80401, United States of America, having made an invention entitled:       METHOD OF FORMING IN SITU OIL SHALE RETORTS     the following disclosure contains a correct and full description of the invention and of the best mode known to the inventor(s) of taking advantage of the same.            ABSTRACT:    A row of horizontally spaced apart in situ oil shale retorts is formed in a subterranean formation containing oil shale.   Each row is formed by excavating at least a pair of upper and lower retort access drifts at eleva-tions within the top and bottom boundaries of the retort sites.   The access drifts extend through opposite side boundaries of a plurality of retorts in such row.   Each retort is formed by excavating upper and lower horizontal voids at the levels of the upper and lower retort access drifts, respectively, such voids being excavated later-ally from the access drift within the side boundaries of the retort sites.   Each retort is formed by explos-ively expanding formation toward the upper and lower voids within the boundaries of the retort site to form a fragmented permeable mass of particles containing oil shale in each retort.   Following formation of each retort, the retort access drifts on the advancing side of the retort are at least partially sealed, preferably with a mass of formation particles covered by a gas impermeable layer and backfilled with a further mass of formation particles.

Abstract: AUTOMATIC TRACKING SERVO CONTROL SYSTEM               ABSTRACT OF THE DISCLOSURE An automatic tracking servo control system which is adapted to control the tracking of at least one rotary signal reproducing head which scans successive-parallel record tracks on a movable record medium.  Position pulses are generated when the at least one head rotates into predetermined position with respect to the record medium, and these position pulses are used in conjunction with control signals which are reproduced from the record medium and which had been recorded at spaced locations there-along in predetermined relation to the record tracks for controlling the position of the at least one head with respect to the tracks scanned thereby.  A detector detects the relative strength of the signal reproduced by the at least one head during periodic intervals.          A phase shift circuit shifts the phase of each reproduced control signal as a function of the difference between the relative signal strengths in successive periodic intervals.  The phase-shifted control signal is used in a servo circuit, together with the position pulses, to control the tracking of the rotary head.           -i-

This is followed by again recor-ding the spectra of the samples being analyzed and of the standard samples and superposing the first and second spectra of the samples being analyzed and of the standard samples.          These spectra are then shifted relative to each other along the energy axis, and the contents of the elements being ana-lyzed are determined by thus comparing the spectra of the samples being analyzed and of the standard samples.
