Abstract: ABSTRACT         A power transmission method and apparatus for driving a road planar machine has the cutter unit in a positive mechanical drive with the drive shaft of a machine power unit through a hydraulically actuated clutch mech-anism.  The wheel traction units for the machine are con-tinuously driven from the power unit by hydraulic motors operated by variable volume displacement pumps.  A con-trol system for retaining the power unit at a set rota-tional speed required for a predetermined cutting or planing load is responsive to a drop in the set rotational speed, resulting from the cutting unit encountering an overload, to actuate the variable displacement pumps to decrease the forward speed of the machine without appre-ciably reducing the rotational inertia force of the cut-ting unit.  If the cutting unit overload is of a short duration or momentary the set rotational speed of the power unit is resumed.  If the overload, as observed by the machine operator after the occurrence of the drop in the set rotational speed of the power unit, appears to be severe or prolonged, the control system may be manually discontinued and the machine manually controlled until the cutting unit overload has been removed at which time the control system may again be placed into operation.

Abstract: ABSTRACT       Synchronous  demodulation  using  a  lock  in amplifier technique improves substantially the signal to noise ratio in a conveyor belt rip detector.   The lock in amplifier technique uses an analog multiplier to form a product of a received AC transmitter signal, i.e. that received by the rip detector receiver from an antenna  carried  by  the  conveyor  belt,  and  an  AC reference signal, which has the same frequency as the transmitted   AC   transmitter   signal,   i.e.   that transmitted by the rip detector transmitter.   A shift in the phase of the AC transmitter signal as  it is coupled from the transmitter to the receiver requires a corresponding shift in the phase of the AC reference signal so that the latter is tuned to the same phase as that of the received AC transmitter signal.       The invention lends itself to computer control and  self  diagnosis  of  faults  of  the  overall  rip detector system.   To effect such fault detection not only is there produced an AC transmitter signal and an AC reference signal, but there also is produced a test signal  representative  of  proper  operation  of  the transmitter,  and this  parameter  is  checked to learn whether a rip has occurred causing an antenna not to be sensed at an expected location on the belt or a fault has occurred in the rip detector equipment.

Abstract: AUTOMATIC CONTROL APPARATUS FOR CHORDS                      AND SEQUENCES                  Abstract of the Invention Electronic and logic circuitry for an automatic tonal bass rhythm accompaniment feature and an automatic chord feature in an electronic organ.  Automatic bass rhythm accompaniment produces a pattern of notes based upon a tonic note selected by the instru-mentalist such that the desired musical effect is produced when the pattern of notes is combined with the notes being played by the instrumentalist.  The electronic organ has stored in a memory various rhythm patterns which can be selected by the instrumentalist by closing rhythm switches.  Electronic circuitry then causes notes for the selected rhythm pattern or patterns to be played automatically in response to the actuation of a pedal switch or keyswitch.  The automatic chord feature of the present invention provides selectively major triad and dominant seventh chords or minor triad and diminished seventh chords automatically in response to the selection of a root note by the instrumentalist.

Abstract: PRINT HAMMER LIMIT CONTROL            Abstract of the Disclosure A hammer limit control for an on-the-fly line printer comprises a counter which counts compare signals from a compare circuit which detects coincidences of print data and type position data in synchronism with the motion of an endless type carrier.          The counter maintains a running count of the number of compare signals for a control interval having a duration which is a function of the printing interval of a print line cycle.  A hammer on storage device stores a plurality of compare counts registered by the counter at the end of each of a plurality of control intervals.  An adder adds the running count registered in the counter to the total count stored in the storage means and stores the total sum in a hammer on register.          When the total sum in the hammer on register equals a maximum number, a limit comparator generates a control signal which inhibits further comparisons by the compare circuit.  The content of the hammer on storage device is updated each control interval by transferring the compare count registered in the compare counter to the storage device and by deleting the oldest count in the hammer on storage after a predetermined number of control intervals.  The maximum number is stored in a register which is programmable.

Abstract: TIE-BACK CONNECTION APPARATUS AND METHOD            Abstract of the Disclosure A   tie-back   connection   apparatus   effects   3 metal-to-metal  type  seal  between  a  riser  run  from  an overhead vessel and a subsea well casing suspended from a casing hanger in a subsea wellhead member.  The apparatus includes a tubular mandrel  connected  to and  run by the riser  into the wellhead.   A metal-to-metal  type annular seal  ring, mounted at the lower end of the mandrel,  is landed upon the casing hanger, with the end of the mandrel in coaxial alignment with the casing hanger.  The seal ring effects  a  seal between  the  riser  and  the  casing  when compressive force is applied  to  the  seal  ring.   A seal activating mechanism,  operated  by  a  tool  run  from  the vessel,  engages  the  casing  hanger  and  applies  the compressive force to effect the seal.  The seal activating mechanism  includes three locking  collects,  a  reaction sleeve, and a drive sleeve.  One collet engages the casing hanger.  The tool first rotates the drive sleeve to move the reaction sleeve upwardly to maintain the first collet in engagement the casing hanger and to engage the second locking collet.  Thereafter, hydraulic force is applied to the  reaction  sleeve  via  the  second  collet  to  urge  the mandrel downwardly against the casing hanger via the third collet  to  apply  the  compressive  force  to  the  seal. Thereafter, the drive sleeve is rotated against the mandrel to maintain the compressive force and allow the hydraulic force to be released and the operating tool removed.   A method is also provided for effecting a metal-to metal type seal between the riser and the casing.

Abstract: A CORDLESS KEY TELEPHONE SYSTEM EMPLOYING INFRARED TRANSMISSION            Abstract The present key telephone system comprises cordless telephone stations which communicate over a line-of-sight transmission end link.  The system further comprises a central controller for switching communications between the cordless stations and to the message network.          The central controller does not provide any station to transmission channel concentration.  Concentration occurs in the bidding by a cordless station for access to a channel provided by the line-of-sight transmission end link.  A particular number of transmission channels are provided by the line-of-sight end link which are bid for by any practical number of cordless stations. Subsystem controllers are provided in a large cordless key telephone system.  The subsystem controller reformats data for transmission between the central controller and a cordless station.  A unique code identifies a cordless station so that the allocation of a new channel to a cordless station may occur automatically when a cordless station is detected within the boundaries of a new subsystem.

Abstract: ABSTRACT OF THE DISCLOSURE A new cross-linked polyester amide containing an ester amide chain of the following formula in the polymer chain:       [wherein R and R' are each a bivalent hydrocarbon radical; and n is a positive integer], which may be obtained by the reaction of a bis(2-oxazoline) compound and a dicarboxylic acid, wherein at least 5 % of the -NH- groups of the ester-amide chain are cross-linked with a 2-oxazoline ring by a ring-opening addition reaction.  The cross-linked polyesteramide is tough and excels in abrasion resistance and solvent resistance and can be utilized in the molding of machin-ery parts such as rolls and gears and embedded molding of electrical machinery and apparatus parts as well as for electric insulating materials and dental materials.  The invention also relates to a resin composition comprising the cross-linked polyesteramide and about 3 to 95 weight % of a reinforcement material and/or a filler which can provide a molding material having excellent mechanical properties, especially outstanding toughness, beyond that expected for conventional fiber-reinforced plastics and other superior characteristics such as its thermal properties.  The resin composition can be utilized not only for conventional fiber-reinforced plastics applications but also in areas where conventional fiber-reinforced plastics have proved unsatisfactory.
