Abstract: A FIBRE NETWORK HAYING A PASSIVE OPTICAL COUPLING ELEMENT    FOR OPTOELECTRONIC TRANSMISSION OF DATA BETWEEN        ADDRESSABLE SUBSCRIBER STATIONS            ABSTRACT:           A fibre network is disclosed for the optoelectronic transmission data between and among a plurality of subscriber stations, each station having a transmitter and a receiver.          A specific address code is allocated to each transmitter and its associated receiver, and the information content of the individual subscriber stations is sample cyclically by a common addressing unit.  The fibre network has n junction points, whereby n ? 1, and the individual fibre conductors lead from these junction points to the connected subscriber stations, in which the junction points contain passive coupling elements in the form of a solid, light-conducting core having opposing end faces.  The fibres leading from the transmitters and from the addressing unit to a junction point are optically connected to one end face of a coupling element, and the outgoing fibres leading to the re-ceivers are optically connected to the opposite end face of the coupling element.  The length of the coupling element is such that the active surface area of the light-transmitting fibres coupled to the coupling element are individually capable of fully illuminating all of the receiver fibres connected to the opposite end face of the coupling element.  In an alterna-tive embodiment, the fibres leading from both transmitters and receivers are optically connected to the same face of the coupling element, whose opposite end face is provided with a reflective (i.e. mirror) surface.

Abstract: ABSTRACT OF THE DISCLOSURE       A control valve is activated by a first plunger upon movement of an input bush rod to develop a pressure differential across a movable wall which produces an output force.  This output force is carried through a first piston on which a concentric second piston is retained between a first stop and a second stop.  A spring urges the second piston toward the first stop in opposition to a first hydraulic pressure developed by the second piston ?ov'?c in a pressurizing chamber.  When the first hydraulic pressure is sufficient to hold the second piston against the second stop a ball valve connected to an output chamber is closed.  The first hydraulic pressure will unseat the first ball valve until an input force moves a second plunger to proportionally open a poppet valve and allow a po tion of the first hydraulic pressure to escape into a relief chamber. As the first hydraulic pressure is reduced, the movable wall moves the first piston in the output chamber to develop a second hydraulic pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           The analog signals provided by a seismic-velocity well logger, resulting from the transmission of seismic impulses from a transmitter to a receiver in a logging sonde in a well by paths that include travel through the rock walls of the borehole, are digitally recorded.  These seismic impulses and the resulting received seismic signals, or traces, are repeated approximately 20 times per second.  The recording apparatus digitizes these analog traces by determining signal amplitudes at intervals of approxi-mately 10 microseconds and temporarily stores the digital values.     The apparatus includes a programmable-gain amplifier, an analog-to-digital converter, a computer, and a memory in which are, in addition to the data, also stored the values of gain which are to be used in digitizing the next signal.  That is, on each digitiz-ing interval a stored gain "program" is read out of the computer and sets the gain of the amplifier.  Besides transferring the stored data to a standard computer input tape, a digital-to-analog converter and a scope are provided for displaying the successive values of gain and digitized signal, for monitoring the operation of the apparatus.

Abstract: DRIVE MECHANISM FOR COMPUTER FORM FEEDER APPARATUS             ABSTRACT OF THE INVENTION            A mechanism for driving a computer form web along a pre-determined path includes a ratchet wheel having two sets Or oppositely facing teeth, mounted on a support shaft for rotation.   The wheel is driven in both clockwise and counter-clockwise directions.  A drive gear in meshing engagement with a plurality of gears for driving the sprocket mechanism transporting the computer form web is also mounted on the support shaft for rotation.  The gear is joined to a coupling plate also mounted on the support shaft for rotation thereon.  The coupling plate includes first and second pawls which extend therefrom for cooperative engagement with the ratchet teeth sets, respectively.  Pawl actuator arms also mounted on the coupling plate are movable to first and second positions and when in a first position engage the pawls to maintain the latter out of engagement with respective ratchet teeth sets.  Pawl actu-ator arm engaging levers are mounted adjacent the pawl actuator arms and are movable to first and second positions.  When in the first position the levers engage the pawl actuator arms to maintain them in the first position.  Movement of the lever arms to the second position permits the pawls to be moved toward the ratchet wheel.  Depending upon the direction of rotation of the ratchet wheel, one or the other of the pawls engages a tooth of a corresponding ratchet teeth set, thereby coupling the rota-ting ratchet wheel to the drive gear.  Returning the levers to their first position permits engagement therewith by the actuator arms revolving on the rotating coupling plate, to urge the actuator arms to the first position, thereby moving the pawls away from the ratchet teeth for dis-engagement of the engaged pawl and ratchet tooth.  This action discontinues the rotation of the gear member and stops the driving of the computer form web.  Control of movement of the lever arms in turn control the number of revolutions of the drive gear and thus the extent of movement of the computer web along its path.  A manually operated gear selector for providing a change in gear ratios controls the length of movement of the com-puter web for each revolution of the drive gear.  Continual rotation of the drive gear can be achieved by maintaining the lever arms in the second posi-tion.
