Abstract: TELEPHONE MESSAGE TIMING SYSTEM     Abstract of the Disclosure A timing arrangement for use with a telephone switching system having automatic message accounting equipment at a recording center to adjust apparent call duration times to compensate for delays caused by the temporary storage of call data at remote telephone offices.          Cycling, counting apparatus is provided at each of the remote telephone offices to generate sequential time interval data representative of successive time intervals.          Logic apparatus combines the time interval data with telephone office trunk random answer and disconnect event data to form a plurality of first data words in a buffer store.  Transmitting apparatus responds to command of the recording center by transmitting a block of first data words from the buffer store followed by a final data word identifying the current time interval data to the recording center.  At the recording center, a comparison of the time interval data in each received first data word with the final data word generates delay times utilized for adjust-ing the apparent time of day of the answer and disconnect events to compensate for delays encountered in transmitting the event data.

Abstract: ABSTRACT OF THE DISCLOSURE A variable reluctance motor of the stepper type is operated as a brushless constant speed DC motor by sensing the position of the rotor during rotation and generating a tachometric signal representing the speed of the rotor in response to the sensed position of the rotor.  The tachometric signal is compared with a reference signal to generate a supply voltage to the windings of the stepper motor which will maintain the speed of the rotor substantially constant.  The windings of the stepper motor are sequentially energized by the supply voltage in response to sensed position of the rotor.  During start-up and prior to the time the motor reaches the predetermined speed, a start-up signal is utilized in addition to the sensed rotary position to sequentially energize the windings with the supplied voltage.  The motor is utilized to drive a floppy magnetic data storage disc.

Abstract: VISCOUS OIL RECOVERY METHOD      (D#73,500-RCA 33-F) ABSTRACT OF THE DISCLOSURE            Viscous petroleum may be recovered from viscous petroleum-containing formations such as tar sand deposits in a process employing steam and air or a free oxygen-containing gas in the ratio of 0.05 to 0.65 M.S.C.F. per bbl. and a cyclical injection-production program in which first steam or steam and air are injected and fluids are produced without restriction until live steam is produced at the production well, after which steam and air are injected and production throttled to a value less than 50% and preferably less than 20% until the formation pressure at the production well rises to a value between about 60% to 95% of the steam injection pressure, after which fluid production is permitted without restriction and steam and air injection is reduced to a value less than 50% and preferably less than 20% of the original injection rate.  The process should be applied to a formation in  which  adequate  communication  exist or  in  which  a communication path is first established.  The air and steam in the optimum ratio cause a low temperature, controlled-oxidation reaction in the formation.  Optimum results are obtained  if  the  pressurization  and  drawdown  cycles  are initiated  shortly after  the  beginning  of  the  steam-air injection program, and the process results in substantially increased oil recovery efficiency at all values of steam pore volumes injected.

Abstract: ABSTRACT OF THE DISCLOSURE      A resettable thermal cut-off fuse, under normal temperature condition, keeps the circuit in a closed state by allowing a switch member which is energized by a spring in the circuit-breaking direction to be joined through the medium of a thermal pellet capable of retaining a solid state under the normal temperature condition to a check means which is prevented from rotating in the spring's energizing direction.  When the ambient temperature rises to a prescribed level and, consequently, the thermal pellet melts, the fuse allows the switch member to rotate in the spring's energizing direction to open the circuit.  When the ambient temperature falls and returns to its normal level, the fuse can be manually reset by rotating in the circuit-making direction until it resumes firm engagement with the check means to close the circuit.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for converting ocean surface wave energy into useful rotational kinetic energy. A refractive horn and ramp provides reflection-less impedance transformation of ocean surface wave energy at the input to the system.  Wave energy, in the form of breakers, which are massive pulses of essentially pure kinetic energy, from the output of the horn ramp are then smoothed and transformed directly to mechanical rotation.  Smooth-ing is accomplished by the inertial properties of a "liquid flywheel".  The rotational kinetic energy may be extracted by means of a turbine to provide useful work.  Discharged water is returned to the ambient ocean through a low   terminal velocity diffuser.  The entire structure may be located offshore and the discharged fluids may be used for auxiliary purposes.

Abstract: ABSTRACT OF THE DISCLOSURE      A rotatable print disk is mounted on a carrier which traverses along the print line.  The disk is moved from each character position to the next by the shortest distance at a constant velocity; thus, the time for the disk to move from a given character position to the next will be variable dependent on this distance.  The carrier is moved from one print position to the next, a fixed distance, at a variable speed selected in order that carrier reach the next print position in synchronization with the disk reaching the next character position.  Upon such synchronization, a print hammer is fired to print the character while the carriage continues on-the-fly towards the next print position.  The apparatus includes means responsive to a synchronization failure for reversing the movement of the carrier towards the previous printing position while permitting the continued movement of the print disk to the next character position, and means for then reinitiating the forward movement of the carrier towards the next print position while retaining the print disk at said next character position until the arrival of the reinitiated carrier at the next print position.
