摘要： A composite for constructing an article which is composed of a nonmetallic substance as represented by igneous rock of different particle sizes which are compacted and then surrounded by a solidified plastic resin. In a preferred manner, the igneous rock material is a selected type of basalt with the basalt particles being of different mesh sizes to be compacted into a mold. After compaction, the plastic resin as represented by an epoxy resin is introduced into the mold so as to displace air from any voids surrounding the basalt particles and to surround them with a resin which later solidifies. A novel resin delivery system is also presented.

摘要： An automatic dynamic error compensator for compensating the position error arising within a servo drive system includes a measuring head which is operative to measure the relative indicated position of two or more measuring vanes on the movable member. The measuring head, together with a feedback transducer, that measures indicated movable member position, are coupled to a feedback system. The feedback system determines the indicated movable member position from the feedback transducer reading and then compares the indicated movable member position to the known vane position upon occurrence of a vane crossing to yield a compensating value.

摘要： A voice actuated control system suitable for use on a computer numerically controlled (CNC) machine tool includes a pair of radio frequency transmitters and a pair of radio frequency receivers, one of the radio frequency receivers and one of the radio frequency transmitters being located at the machine tool site and the other radio frequency receiver and radio frequency transmitter being carried by the human machine tool operator. Operator-spoken commands are transmitted through the operator's transmitter to the machine tool receiver which outputs an audio signal to a voice interpreter that converts the received voice commands into digital signals which are transmitted to the CNC machine tool control system to control machine tool operation. Digital signals generated by the CNC machine tool control system, either in response to received operator commands or in accordance with variations in machine tool operating conditions, are converted by a speech synthesizer into synthesized audio signals representing speech phrases indicative of machine tool operation conditions. The speech synthesizer audio signals are transmitted to the operator to audibly inform him or her that the previously transmitted voice commands have been received or that further instructions are required.

摘要： In apparatus for controlling the speed and torque of a multiphase a.c. motor in accordance with digital control signals, a first regulation circuit regulates the frequency of the a.c. electrical signal applied to the motor and another regulation circuit regulates the voltage of the a.c. signal. Both regulation circuits are controlled by digital control signals in a series of discrete steps over a range of control values and the control signals are supplied periodically to the regulation circuits. The speed and torque are controlled in accordance with an algorithm relating speed and torque to the frequency and voltage of the source of electric power which is applied to the motor, calculated by computing apparatus on a periodic basis. In one embodiment the position of the magnetic flux of the stator is controlled directly.

摘要： The tape in a tape reader is braked to a stop relatively slowly instead of being stopped on one character. Two sprocket reading photocells are mounted on the tape reader to provide quadrature sprocket waveforms which are applied to a bi-directional sprocket counter coupled to the address conductors of a buffer memory. The data read off the tape by the tape reader is written into the buffer memory at the addresses indicated by the sprocket counter. An output pointer counter is also coupled to the buffer memory address conductors in parallel with the sprocket counter through a time division multiplexer. During the time interval in which the output pointer counter is connected to the buffer memory address conductors, data can be read out of the buffer memory at the address indicated by the output pointer counter independently of the sprocket counter.
