Abstract: DIALING INTERVAL TRANSMISSION GATING ARRANGEMENT            Abstract of the Disclosure A transmission arrangement for use in a customer premises communication system is operable for controlling transmission during the MF digit signaling interval in situations where it is necessary to convert station dialed MF signals to pulsed digit signaling.  In systems where the signaling station, the MF to dial pulse converter and the Central Office or PBX line are bridged on the same communication link it is possible for the station's MF signals to be detected by the MF receiver in the Central Office, thereby causing errors in the received digits. These problems are eliminated by inserting two transmission gates in the four-wire portion of the CO line.  The gates are controlled by the processor in the customer premises communication system such that the outward gate is opened immediately upon seizure of the line by the calling station and remains open during the entire dialing interval.  The inward gate is opened concurrently with the operation of the digit outpulsing relay and remains operated on a digit by digit basis.

Abstract: ABSTRACT Screening apparatus for treatment of flowing suspensions, especially fiber containing cellulose material in liquid, by extraction of liquid and possible addition of displacement liquid.  Problems with clogging of screen body perforations and proper movement of suspension through the apparatus have previously been solved by periodic backflushing of the perforations taking place as a result of the screen body having an interior cavity volume with changing dimension when the screen body is driven forward and backward in the direction of suspension flow.  The improvement disclosed herein lies in a conical or wedge-shaped screen body of decreasing cross-section in the direction of suspension flow and a baffle plate arranged along the extraction side of the screen surface, said baffle plate being stationary or movable relative to the screen body.

Abstract: SUBSCRIBER LINE INTERFACE CIRCUIT          ABSTRACT OF THE DISCLOSURE         A subscriber line interface circuit for coupling a balanced communication line with unbalanced bidirectional or a pair of unidirectional communication lines.  Line current is fed to the line via a low resistance path for maximum current supply, via a circuit which matches the line impedance, and also provides high resistance protection to the output of amplifiers feeding the balanced line.  Since a low resistance d.c. current feed is used, a voltage boost is not required.  However lightning protection is obtained for the outputs of the amplifiers which feed the line at the same time as virtually optimum line impedance matching and sufficient line current feed.  The circuit is comprised of a balanced line including a lead pair, a pair of matched feed resistors for providing a low resistance path, each connected to one of the pair for applying a d.c. line current from a power source to the line, the total resistance of the feed resistors being a fraction of the d.c. line impedance.  A circuit is provided for receiving a signal from the balanced line, and a further circuit applies a predetermined amplitude of the signal received from the balanced line back to the balanced line with a signal aiding polarity to as to raise the apparent impedance of the line for the signal at the lead pair, while allowing d.c. line current to be fed to the line via the low resistance path.

Abstract: ABSTRACT OF THE DISCLOSURE         For use in transmitting power from an engine or engines a planetary gear assembly adapted to be couple to first and second discrete sources of rotary power by first and second output coupling means, respectively, the assembly having a primary driving member, a secondary driving member and a driven follower member.  The primary driving member is adapted to be coupled by the first output coupling means to the first discrete source of rotary power and the secondary driving member, by the second output coupling means to the second discrete source of rotary power.  The driven follower member is other than the planetary carrier cage of the planetary gear assembly.  The first and second discrete sources of rotary can be provided by either separate motors whose output speeds relative to one another can be controlled or by a single engine with a suitable engine source coupling means.  In the former case both first and second coupling means may be non-slip in which case the output speed is determined by both the absolute and relative speed at which the two motors operate whereas in the latter case, at least one of the first and second coupling means must be slippable in order to allow for acceleration and deceleration to occur without significantly modifying the engine speed.  It is possible to couple two or more planetary gear assemblies in tandem to get greater gearing down than is available in a single stage.  By allowing both inputs to vary, a planetary gear assembly provides a continuously variable, wide range of gearing down or overdrive without the need for mechanical switching of gears.

Abstract: ABSTRACT    A gyrating cone-shaped head cooperates with a stationary bowl to crush rock.  The gyrating action of the head is accomplished by a vertically off-set shaft arrangement for the head driven by a rotatable eccentric member.  This is driven from a bevel gear via a flange set up on a stabilizing shaft and a coupler between the flange and the eccentric member.  The coupler comprises a diametral groove in its bottom surface and a diametral groove in its top surface angled normal to the bottom surface groove.  Spaced keys are releasably secured in the upper surface of the flange and slidably fit in the bottom surface groove of the coupler.          Similarly, the top of the coupler is connected to the eccentric member by spaced lugs fastened on the latter which slidably fit in the top surface groove of the coupler.  This provides precise gear fit adjustment between the gear and the eccentric, that is, by installing shims between continuous parts to permit radial and vertical adjustment.

Abstract: Abstract of the disclosure An adjustable two-piece rope guiding device 21, 26, parti-cularly adaptable for use on offshore guyed bower drilling and pro-duction structures 11.  On such structures it is necessary to de-flect a taut guy rope 14 into a direction that may not be precisely known, or that may vary with time.  Such deflection must not damage the rope by excessive static or cyclic straining or by wearing. To minimize problems of clearance within the structure the guiding is performed in two parts:  1) a permanent deflection into a direct-ion that satisfies the foregoing clearance reqirements and 2) a va-riable deflection occuring beyond clearance problems that completes the required total deflection.  When guiding the guy ropes 14 of an offshore oil production tower 11 from their vertical orienta-tion at the clamping and jacking (tensioning) devices 20 on the tower to a seafloor anchoring system 15, 16 a first bending member 21 changes the vertical direction of the guy ropes 14 to a selected direction (plane) extending toward such anchoring system 15, 16. A second bending member 26 rotates the rope in a new direction at the periphery of the offshore structure 11 to accommodate positions of the anchoring system 15, 16 with respect to the plane of the selected direction.  The first member is a fixed shoe 21 having a grooved rope contacting surface 23 and a sleeve 24.  The second member 26 includes an cuter fixed housing 45 and an inner rotat-able housing 46 having a grooved surface 48 for contacting the rope. me inner surface of the inner housing 46 may have various configu-rations depending upon its application.  In its use with guyed tower anchoring the inner surface is preferably a three-sided pyramidal configuration 52, 53, 54 one corner of which comprises the grooved rope-contacting surface 48.
