Abstract: Abstract Disclosed are methods and apparatus for surveying a borehole including use of a survey instrument for making gravitational measurements from which the inclination and highside angles of the instrument may be determined. Measurements of two components of the local magnetic field perpendicular to the longitudinal axis of the in-strument may be sensed with the instrument, and may be used to determine the azimuth angle of the instrument under the assumption that magnetic interference due to the pipe string in which the instrument is located lies solely along the longitudinal axis of the instrument. The accuracy of the azimuth determination may be enhanced by an iteration process.  To the extent that the pipe string interference includes transverse field components at the instrument, the sensors of the instrument may be separated from such pipe string members by placing the instrument in non-magnetic material whose minimum length may be determined.

Abstract: Abstract A digital automatic frequency control for a pulse-type radar receiver having a voltage controlled local oscil-lator.  A first digital number is generated and converted to a first analog voltage for coarse control of the local oscillator frequency.  The first digital number is varied during the time output from the radar transmitter is pres-ent at the receiver mixer.  The first digital number is varied causing sweep of the local oscillator frequency.          When the difference frequency output from the mixer is at a value to cause output from the receiver intermediate frequency amplifier of a predetermined level, variation of the first digital number is halted, providing a coarsely tuned local oscillator frequency.  A second digital number is then generated, converted to a second analog voltage which is combined with the first analog voltage.  The second digital number is varied to cause the local oscil-lator frequency to be sidestepped above and below the coarsely tuned frequency.  Samples of the receiver output are separately accumulated for sidesteps above and below the coarsely tuned frequency.  The difference between the separated accumulated outputs is used to generate a third digital number which is converted to a third analog volt-age.  The third analog voltage is combined with the first analog voltage to fine tune the local oscillator frequency.

Abstract: ABSTRACT      Sensing arrangements on material rolls are used to give advance warning when the material web forming the roll approaches its end.  Usually this involves the sensing of the reduction of the roll diameter with the help of a sensing device resting against the roll periphery.  In the case of roll suspensions where the centre of the roll is not fixed, these sensing arrangements cannot be used.  Here it is possible instead to use a sensing arrangement which comprises a field-generating element e.g. a permanent magnet, present in the centre of the roll together with a movable sensing device     resting against the periphery of the roll, e.g. a heavy current switch which is acted upon at a certain predetermined field strength, and in a suitable manner indicates that a roll replacement is imminent.

Abstract: PROCESS FOR PREPARING HIGHLY OPTICALLY TRANSPARENT/COLORLESS AROMATIC POLYIMIDE FILM                 ABSTRACT OF THE DISCLOSURE    An aromatic condensation polyimide film that is approximately 90% transparent at 500 um, useful for thermal protective coatings and the like and the process for preparing same are disclosed.  An essential feature of the invention for achieving maximum optical transparency films requires utilizing recrystallized and/or sublimated specific aromatic diamines and dianhydride monomers and introducing bulky electron-withdrawing groups and separator groups into the polymer molecular structure.  The incorporation of bulky electron-withdrawing groups in the diamine portion of the polymer structure serves to reduce the formation of inter-chain and intra-chain charge transfer complexes which normally cause large absorptions in the UV-visible range. Incorporation of separator atoms into either the diamine or dianhydride monomers serves to reduce the amount of conjugation and inter- and intra-chain electronic interactions and thereby lessen charge transfer complex formation.

Abstract: SUPERCONDUCTING FILTER COILS FOR HIGH HOMOGENEITY                  MAGNETIC FIELD                   ABSTRACT OF THE DISCLOSURE           When a closed circuit is formed by joining super-conducting wires with superconducting joints, the current in that circuit adjusts itself as required to maintain whatever total flux linkage the circuit had at the instant supercon-ductivity was achieved.  In particular, a closed circuit which first becomes superconducting under conditions of zero net flux linkage maintains zero net flux linkage as long as the circuit remains superconducting.  By appropriately configuring a set of short-circuited superconducting coils, a field inside a volume described by the coils is kept substantially more uniform than it would be if the same volume were magnetized by the same source in the absence of the short-circuited coils.  This property is used to insure that the volume within the coils exhibits improved magnetic field homogeneity.
