摘要： Two transistors each have their emitter-collector circuits coupled in series between one end of a motor field winding and the opposite terminals of a D.C. voltage source to switch current flow in either direction through the winding. Two current sensors are provided, one coupled in series with each emitter-collector circuit. The voltage developed across each current sensor is applied through a driver circuit to the base of the other transistor so as to cut one transistor off when the other is conducting and vice versa, thereby eliminating the possibility of having both transistors conduct simultaneously which would short out the voltage source and burn out one or both transistors.

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： A servo system for the rotary spindle of a machine tool in which the spindle is driven by a drive motor through a gear train having shiftable gears for changing the rate of rotation of the spindle. The transducer for the servo system is mounted directly on the motor drive shaft in order to avoid all backlash between the resolver and the drive motor. However, the transducer is arranged to regulate the angular orientation of the spindle and must therefore be maintained in synchronism with the spindle. This is accomplished by arranging the shiftable gears so that when they are moving into engagement with a new gear, engagement with the previously engaged gear is maintained until initial engagement with the new gear is achieved. Further shifting movement into full engagement with the new gear operates to release the previously engaged gear. Thus, during the initial engagement with the new gear, the shiftable gear is momentarily in engagement with both gears. As a result, there can be no relative movement between the gears and synchronism with the transducer is thereby maintained.
摘要翻译：一种用于机床的旋转主轴的伺服系统，其中主轴由驱动电动机通过具有用于改变主轴的转动速率的可移动齿轮的齿轮系驱动。伺服系统的传感器直接安装在电机驱动轴上，以避免旋转变压器和驱动电机之间的所有间隙。然而，传感器被布置成调节主轴的角度定向，因此必须与主轴保持同步。这是通过布置可移动齿轮来实现的，使得当它们移动到与新齿轮接合时，保持与先前啮合的齿轮的啮合，直到实现与新齿轮的初始啮合。进一步的换档运动与新齿轮的完全啮合操作以释放先前啮合的齿轮。因此，在与新齿轮的初始接合期间，可换档齿轮暂时与两个齿轮接合。结果，齿轮之间不存在相对运动，从而保持与换能器的同步。

摘要： The voltage and frequency of an A.C. excitation signal applied to the stator windings of an A.C. induction motor are varied in proportion to the amplitude of current flowing in the stator windings. The stator current flow is sensed by a feedback resistor in series with the inverter which generates the A.C. excitation signal for the stator windings. The voltage drop aross the feedback resistor is summed with a VELOCITY COMMAND voltage which indicates the desired speed of the motor and the summed voltage controls the frequency and the amplitude of the A.C. excitation voltage in a constant volts per hertz manner. The stator current feedback holds the motor speed constant in spite of variations in the load on the motor.

摘要： A golf club is disclosed that can be used with a structure of a golf club head that has a space between the front striking face and the back piece of the club head. The front face and the back piece are attached to each other at the heel edge and the toe edge. This new club head can replace the presently used perimeter weighting with this new heel and toe weighting. This new club head is able to strike a golf ball more accurately and with more control. With rotation of the shaft on the club head, the golf club can become a four way device whereby the front face, the back face, the heel edge or the toe edge may be used to strike a golf ball. With a rotatable shaft that is moveable on the golf club head at the heel edge, at the toe edge or at the central part of the back piece, the golf club can become a four way device for a left hander or a right hander. The front face, the heel edge, the toe edge or the back face can be used to strike a golf ball. An adjustable length or telescopic shaft allows more control and accuracy to strike a golf ball.
