Abstract: IMPROVED WELL LOGGING SYSTEM AND METHOD          ABSTRACT OF THE DISCLOSURE     An improved well logging system and technique is pro-vided for correlating historically derived measurements with new measurements being derived at correlative depths as the well is logged.  A logging sonde generates and de-livers to the surface digital logging data in realtime as A function of preselected depth intervals.  This data is merged with compatible digital data which is historical in character and derived at correlative depths.  The realtime and historical measurements derived at the same borehole elevations are correlatively matched for realtime record-ing, display and processing of the matched data.  A con-verging technique is provided for accomplishing the initial merger independent of the direction of logging, the relative starting elevation of the sonde and historical data, and whether the realtime logging has begun prior to the merging process.  Provision is made for transmitting from one or more remote observation and control sites the historical data employed in the merger, for transmitting the merged data to a remote location, and for transmitting from the remote location to the well site control signals in response to the merged data received by the remote site.

Abstract: CHUCK ASSEMBLY AND COLLET                Abstract of the Disclosure A chuck assembly and collet for retaining an end mill tool  against  axial  pullout.  The  collet  includes  a radially compressible body having a tapered outer surface, a central bore and a radial aperture extending from the outer surface into the central bore.  The radial aperture, which includes larger and smaller diameter portions, has a movable pin mounted therein and adapted to extend into the bore to retain the tool.  The pin has an undercut portion, with a spring or snap ring mounted around the pin in the undercut  portion,  said  spring  having  a  free  diameter slightly larger  than the  larger diameter  to provide a pressure fit when mounted therein.   The undercut has a length which is larger than the thickness of the snap ring to allow a limited radial movement of the pin to lock and to release the tool, whereby the pin is urged inwardly into the bore and engages a rear bevel end on a flat surface on the tool to secure the tool within the collet as the collet is tightened within the chuck assembly and whereby the pin can move outwardly to release the tool when the collet is removed from the chuck assembly.

Abstract: IMPROVED MOBILE CLEANING UNIT     Abstract A mobile cleaning unit for providing a high pressure cleaning spray/ comprising a van-type vehicle with separate sources of water and cleaning and treating solutions.  Valves, one associated with each source, determine the composition of the cleaning spray by individually controlling both the introduction and the proportion of cleaning or treating solution introduced into the water as it is used in cleaning. The individual valves are successively operated in response to each initiation of flow from the source of water.  The cleaning or treating solution from a particular source to be used is selected by starting and stopping flow from the source of water by operation of a flow control valve at the spray applicator.

Abstract: - 34  -                    RCA 73,587 Abstract of the Disclosure A system is provided which synthesizes stereophonic sound by developing two separate sound channels from a single monophonic sound source.  A synthetic stereo-phonic sound system constructed in accordance with the principles of this invention may be advantageously utilized in combination with a visual display such as a television receiver.  A monaural signal (M) is applied as the input signal for a transfer function circuit of the form  H(s),  which modulates the intensity of the monaural signal as a function of frequency.  The intensity modulated  H(s) signal is coupled to a reproducing loudspeaker, and com-prises one channel (B) of the synthetic stereo system.  The H(s)  signal is also coupled to one input of a differential amplifier (40).  The monaural signal (M) is coupled to the other input of the differential amplifier (40) to produce a difference signal (M-H(s)) which is the complement of the  H(s)  signal.  The difference signal is coupled to a second reproducing loud-speaker, which comprises the second channel (C) of the synthetic stereo system.  In accordance with a preferred embodiment of the present invention, a stereo synthesizer is utilized as the sound reproducing system of a television receiver, with the reproducing loudspeakers located on either side of the kinescope.  The amplitude -vs- frequency response curves of the two output channels (B,C) have crossover points at which the amplitudes of the two response curves are equal, which effectively centers sounds at these frequencies between the loudspeakers.  Two crossover frequencies are chosen to occur at approximately the frequency of peak intensity of the human voice, and at the center frequency of the second (articulation) formant frequencies of the human voice so as to effectively center voices on the kinescope while preserving the ambience effect of other, more randomly distributed sound signals.  Centering the second formant frequencies also provides increased quality in the reproduction of speech sounds.

Abstract: TITLE OF THE INVENTION     LOCK MECHANISM WITH                  REMOVABLE CYLINDER HOLDER     A door lock including a mounting structure secured to a door, a bolt movable into an extended position in which it projects from an edge of the door, a lock cylinder for operating the bolt, and a holder in which the cylinder is mounted. A retaining mechanism, accessible through a release aperture on the edge of the door when the door is open, normally secures the holder to the mounting structure but permits the holder to be released to remove the cylinder. The retaining mechanism can include a latch member that is engagable with the holder under the urging of a spring to prevent the holder from being removed from the mounting structure.  Mutually engagable cam surfaces carried by the holder and the latch member cause movement of the latch member to permit installation of the holder.  Alterna-tively, the latch member can be a screw, eliminating the need for a spring to urge it toward the holder.  The holder can be installed by simple axial insertion into the mounting structure or by a combination of insertion and rotation.

Abstract: ABSTRACT OF THE DISCLOSURE    A tulip-shaped metal part such as a yoke component of a tri-port type constant velocity universal joint is manufactured by single-stage closed chamber extrusion of a solid cylindrical metal rod.  The metal rod is inserted into two opposingly engaged dies to protrude into a space defined in the dies and is axially pressed against an impressed surface to cause gradual and conti-nuous cleavage of the rod into three branched portions, which are forced into three chambers arranged and shaped correspondingly to three petal-like arms of the tulip-shaped metal part.  The branched portions of the metal material are extruded within the three chambers in directions parallel to the direction of the pressing force exerted on the metal rod, with continued application of a back pressure to the extruding portions of the metal material to shape the ends of the petal-like arms during the extrusion-process.

A telephone subscriber's line circuit includes a control stage for applying a current to or absorbing a current from the subscriber's line (8) and comprises an amplifier (1). The circuit has two terminals (2,3 ) for connection to a power source and first and second diodes (6, 7) are connected between the terminals (2, 3) and power supply terminals ( 1-1, 1-2) of the amplifier (1). The diodes (6, 7) are poled to conduct during normal operation of the circuit but when an overvoltage which is greater than that supplied at the terminal 2 or 3 is induced on the line (8) one of the diodes (6, 7) is reversed biassed and becomes non-conducting.          Further diodes (11, 18) and (12, 19) prevent the output transistors (4, 5) of the amplifier (1) being subjected to high voltages which could cause breakdown of their base-emitter junctions. Voltage-limiting elements (13, 14) are connected between the line (8) and the system earth to provide a discharge path for currents in-duced on the line (8).
