Abstract: ABSTRACT OF THE DISCLOSURE          Described herein is apparatus for use in testing a shell from its interior in the region of a bore through that shell.  The apparatus includes a rotatable stem which is inserted into the bore and an arm carried on the inner end of this stem.  This arm includes guide means by which a testing probe is supported and constrained to move between extreme positions where the probe is normal to the interior surface of the shell and where the probe is within the bore and normal to the surface of the bore; the guide means are therefore shaped to correspond to the profile of the surface of the region under test.  In use the stem and arm are rotated to orbit the testing probe around the axis of the bore and the probe can be progressively moved from one extreme position to the other along the guide means so as to cover the whole area of the region under test.

Abstract: METHOD AND APPARATUS FOR RADIO SYSTEM      COCHANNEL INTERFERENCE SUPPRESSION          Abstract of the Disclosure In a radio communication system of the cellular type wherein sets of communication channels are reused in different adjacent sets of cell areas within a common mobile communication service area, each cell base station utilizing a given set of channels in common with other base stations is assigned a different supervisory tone to be modulated on all of its channels.  Any mobile unit receiving such channel transponds the modulated supervisory tone and sends it back to the base station.  At each base station the transmitted and received supervisory tones for any given channel are compared to produce an indication of whether or not the sending mobile unit is actually communicating on the transmitted channel of the same base station.  At each mobile unit, reference tones are generated which are spectrally located between adjacent ones of the possible supervisory tones for the mobile communication area, and the spectral position of a received tone with respect to the reference tones is determined.  Signals representing that determination are translated into a digital character corresponding to the name of the received tone, and that name is compared with the name of the tone for the mobile unit's assigned channel.  A name mismatch is utilized to quiet the mobile unit receiver for the duration of the mismatch.  In addition, if that duration exceeds a predetermined interval, the mobile unit controller is actuated to initiate the dropping of communication on the assigned channel.

Abstract: SILENT RATCHET                         ABSTRACT         A ratchet is provided in which a friction brake ring is employed to engage a pawl with the ratchet teeth in an annular ring or hinge extending from a ratchet tool handle.          The friction brake ring carries the pawl into engagement when the tool handle is rotated in the direction in which it is desired to turn a workpiece.  A spring within the ratchet returns the pawl to a position in which it is disengaged entirely when pressure on the tool handle in the rotational direction of engagement is released.  Thus, the return of the tool handle before a subsequent engaging stroke is accomplished silently and without the characteristic clicking of the ratchet teeth of the hinge passing over the pawl.

Abstract: METHOD OF PROVIDING A SERIES OF FLYER GROUPS MADE UP OF A FLEXIBLE TOTAL NUMBER OF GEOPHONE FLYERS PER GROUP CONNECTED TO A REMOTE DIGITAL ACQUISITION AND TELEMETERING CIRCUIT UNIT (RDATC) OF A FIELD SEISMIC DATA ACQUISITION SYSTEM AND TO EACH         OTHER IN A MANNER WHICH MINIMIZES HELPER MIX UP               ABSTRACT OF THE DISCLOSURE           The method and apparatus of the present invention are described in which connection (and disconnection) of a plurality of geophones associated with a series of stations of a digital seismic data acquisition system is greatly simplified without sacrificing flexibility as to the number of geophone flyers per station or the interval spacing per station and also without the addition of separate subcabling in the internal linkage of the flyer to the field digitizing equipment.  The method utilizes a multiple-phone flyer-jumper connected to one channel of a series of channels of a remote data acquisition and telemetering circuit (RDATC).  Each RDATC acts in combination with a group of geophone flyers, say 1, 2, 3, etc., to store, amplify, filter, gain control and digitize analog data from each group of flyers and then telemeter the data to recording circuitry in the field truck.  Each flyer group can be flexibly made up of two, three, four or more flyer-jumpers; each flyer-jumper includes a central multi-conductor cable segment of say N+1 conductors, where N is an even positive number greater than two, terminating at each of its ends in the central leg of multi-armed connector.  A plurality of series/parallel connected geophones, say 9 in number are used in combination with the central segment.  At the end of the arms of each multi-armed connector pass another conductor cable segment (similar to the central segment, but called the "branch cable segment") in which only two of the cables are actively connected  o the selected conductor pairs of the central segment.  At the other end of each branch cable is a hermaphroditic connector including a 2 male-2 female combination, with connection occurring between 1 male-l female subunit by paralleling them electrically.  In that way either (i) the three geophone conductors of the central cable segment can be flexibly connected to 1, 2, 3, etc., or more similarly located connectors of other flyer-jumpers to increase signal response of the resulting flyer group or (ii) the remaining conductor pair can be connected to outside circuits including the RDATC to actively transfer data from more remotely located geophones of adjacent flyers of interest.  Repairs to flyer-jumper in the field is relatively simple.  Of interest:  each hermaphroditic connector is color coded to facilitate geophone flyer-jumper field setup and connection in a variety of arrangements with a minimum of helper mix up.

Abstract: ABSTRACT OF THE DISCLOSURE         A photosensitive member having at least two electrically operative layers is disclosed.  The first layer comprises a photo-conductive layer which is capable of photogenerating holes and injecting photogenerated holes into a contiguous charge transport layer.  The charge transport layer comprises a polycarbonate resin containing from about 10 to about 75 percent by weight of:                       wherein X is selected from the group consisting of (ortho) CH3, (meta) CH3, (para) CH3, (ortho) C1, (meta) C1 and (para) C1.  The charge transport layer while substantially non-absorbing in the spectral region of intended use is "active" in that it allows injection of photogenerated holes from the photoconductive layer, and allows these holes to be transported through the charge trans-port layer.  This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.
