Abstract: ABSTRACT OF THE DISCLOSURE A multi-channel radio relay system in which various frequency chan-nels are provided in a link between a transmitter and receiver is disclosed. The channels are combined to form a common, high-frequency group using a cascade circuit each branch of which has a circulator and a band-pass filter. The frequencies are allocated such that each channel passes via an equal number of circulators.  The highest frequency is allotted to that circulator most remote from the antenna in the transmitting cascade and nearest the antenna in the receiver or vice versa.  The highest frequency is allotted to the circulator which is disposed at a location of the cascade opposite to that allotted to the lowest frequency.  All the circulators are similarly disposed in their respective cascades.  The filter which is connected to the circulator which is most remote from the antenna in each cascade is detuned to present a centre frequency displaced in the direction of the centre frequency of the adjacent channel frequency.  The system provides compensation for transit time distortion not only for the centre frequency channels but also for the edge channels.

Abstract: ALUMINOUS REFRACTORY COMPOSITION           ABSTRACT:    Refractory compositions containing alumina or aluminum silicate and a phosphate bonding agent can be im-proved by the addition of from 0.2 to 1.5 percent tetra-sodium pyrophosphate (TSPP) in combination with bentonite. The TSPP minimizes the amount of bentonite required for good workability in aqueous formulations for ramming or hand applications, thereby miximizing density and mini-mizing water required for tempering, also extending the storage life of these refractories and maintaining a high percentage of initial workability over a period of several months.

Abstract: ABSTRACT An improved regulated power supply for a Corona Charging Unit.  More specifically, a digitally regulated power supply for the corona charging unit of an electrostatic copying machine in which a sample of the ionic current of the corona unit is utilized in conjunction with digital regulator means to regulate the power supply means establishing the charge of the corona.  The digital regulator means in conjunction with at least one pulse width modulated power supply permits very fast rise and fall times of the power supply current.  Thus, the ability to switch "corona's" on and off in an area of the photoconductor much narrower in width than the width of the corona unit is provided.  Further, between duty cycles of the machine, the regulator stores a representation of the correct operating point of the corona charging unit determined in the immediately prior duty cycle.  In the next duty cycle, the representation is utilized to initially regulate the power supply.  The regulated power supply although having particular merit and utility when employed in a xerographic copier, or the like, also may be advantageously employed, with or without obvious modification in numerous other types of apparatus, e.g.. servomechanisms, printed circuit motor driver, Precipitrons. etc.

Abstract: ABSTRACT OF THE DISCLOSURE          An analog sound signal the time axis of which is compressed is sampled responsive to a write clock signal and the sampled output is stored in an analog shift register having a given capacity, whereupon the stored signal is read out from the analog shift register responsive to a read clock signal the frequency of which is smaller than that of the write clock signal.  The above described operation is alternately repeated, whereby the output signal read out from the analog shift register is compiled for sound synthesization.  The synthesizing junction of the sound signal is controlled by a microcomputer.  To that end, the analog sound signal is sampled responsive to a first predetermined number of write clock pulses at the trailing end portion of each sound element obtainable at each sampling cycle and is converted into a digital signal, while the analog sound signal is sampled responsive to a second predetermined number of write clock pulses which are more than the first predetermined number of write clock pulses at the leading end portion of each sound element obtainable at each sampling cycle and is converted into a digital signal.  These digital signals are stored in a random-access memory coupled to the microcomputer.  The micro-computer is adapted to evaluate the similarity of the data concerning the waveform at the trailing end portion of a preceding sound element stored in the random-acces  memory and the data concerning the waveform at the leading end portion of the succeeding sound element stored in the random-access memory.          Evaluation of similarity of the waveforms is effected by evaluating a mean square error or a mutual correlation function of two sets of data.  The shift amount of the leading end of the succeeding sound element to be joined to the trailing end portion of the preceding sound element is determined based upon the result of the evaluation, whereby a read circuit is controlled to correct the time axis of the succeeding sound element, thereby to achieve continuity of the waveform at the synthesizing junction of the preceding and succeeding sound elements.

Abstract: ABSTRACT OF THE DISCLOSURE Teach assist apparatus is provided for a programmable manipulator arm to precompute a projected fixed path solution during an initial teaching operation.  The projected fixed path solution represents a desired series of work operations of the manipulator arm to be performed with respect to a workpiece in the minimum execution time while the workpiece is moving at a projected velocity.  The teach assist apparatus computes the minimum execu-tion time on the basis of the maximum dynamic capabilities of the manipulator arm being taught.  The teach assist apparatus receives input data represent-ing the positions of the arm relative to the workpiece as the arm is moved during the initial teaching operation to different positions of the station-ary workpiece.  The teach positions of the arm correspond to the desired series of work operations of the manipulator relative to the stationary workpiece.  The teach assist apparatus then formats the precomputed path data for storage into a control memory of the programmable manipulator.          The stored data also include  projected workpiece positions in terms of basic linear displacement units corresponding to positions of the work-piece.  During an on-line replay or playback of the series of work opera-tions, control apparatus is provided to reconstruct the precomputed fixed path solution from the stored data in accordance with dynamic movement of the workpiece.  The control apparatus performs arithmetic computations in accordance with a stored program as determined by the data recorded in the main control memory.

Abstract: Valve Actuator Abstract A valve actuator which is operable alternatively by a motor and manually.  The motor is coupled into the drive train for the actuator through a planetary gear device so as to enable rapid actuation of the valve by the motor.  The motor is coupled through a special one-way coupling to the sun-gear drive of the planetary assembly which permits the motor to drive the sun gear in either direction upon rotation of the motor but prevents rotation of the sun gear when the motor is arrested.  A handwheel is coupled to the ring-gear drive of the planetary assembly through a worm and pinion so that the handwheel may then drive the ring gear under manual operation, but the ring gear is retained against rotation by the worm pinion when the handwheel is idle.  The planet-gear drive serves as the normal output of the planetary assembly and is coupled to the valve spindle through a torque-limiting device.          A position-limiting means is coupled to the valve spindle to arrest rotation of the motor at the opposite limit positions of the valve element.  A torque-limit-ing sensor is coupled with the ring-gear drive to sense the torque transmitted or fed back through the planetary assembly, said torque-sensing device being adjustable to arrest the drive motor when the motor exceeds the said torque.  The setting is independently adjustable for different directions of rotation of the drive motor.
