摘要： Improved traveler and guide rail apparatus for use with a garage door operator includes an elongated guide rail having a longitudinal screw channel and outwardly extending integral flanges disposed along the screw channel. An elongated T-shaped flange extends upwardly from the screw channel. An improved traveler apparatus for use with the guide rail includes a screw-driven traveler and a coupling traveler, each mounted on respective tracks formed by separate outside surfaces of the guide rail. The screw-driven traveler carries a nut engaging a screw in the screw channel through a slot between the flanges and further includes opposed U-shaped channels slidably mounted over the exterior surfaces of the guide rail flanges for slidable movement along the guide rail. The coupling traveler surrounds the screw-driven traveler and a substantial portion of the guide rail and includes a bore in an upper portion thereof, the bore having an interior surface slidably engaging the exterior surface of the screw channel for slidable movement along the guide rail. Upper shoulders of the coupling traveler above the bore are sufficiently close to the T-shaped flange to be guided thereby to prevent undesirable vertical or horizontal movement of the coupling traveler. Also, the coupling traveler is sufficiently relieved in the flange area to accommodate the screw-driven traveler therein. The coupling traveler is further provided with means for connecting it to a garage door, and carries a manually actuable bistable latch for selectively engaging and disengaging the coupling traveler with the screw-driven traveler for respective cooperative and independent slidable movement along the guide rail.

摘要： An improved position control apparatus is disclosed to control a motor-driven door operator to halt movement of a door at an open position and a closed position. The position control apparatus includes a control screw means in the form of a threaded shaft extension of the motor shaft or a threaded rod coupled to the motor shaft which is rotated when the motor is energized. A travel nut is threadedly engaged with the control screw means and is constrained against rotational motion so as to reciprocate along the control screw means. Position detection means, such as switches, are disposed near the control screw means for actuation by the travel nut to control the motor as the door approaches the open position and the closed position. In another embodiment, a toggle switch is mounted on the travel nut, and the switches are replaced by stops for actuation of the toggle switch to control the motor. An improved obstruction detector apparatus is also provided to control the motor if an obstruction is encountered as the door moves between the open position and the closed position. The obstruction detector apparatus includes a safety switch which is actuable by rotation of the motor casing due to reaction torque, if an obstruction is encountered as the door moves in one direction, and a lever that is actuable by rotation of the motor casing, if an obstruction is encountered as the door moves in an opposite direction, to actuate the safety switch.

摘要： An AC induction motor for driving a varying mechanical load is powered via a Triac switch electrically inserted in series with the motor and its AC supply. A low ohmic value resistor, also in series with the motor, continuously samples the load current. When the peak value of the sampled load current is below a predetermined value indicative of a near full load condition, the Triac is switched to a conducting state at a predetermined electrical angle from each immediately preceding trailing edge of the sampled load current pulses or of sampled line voltage pulses applied to the motor. Such a phase triggering switching scheme reduces the power applied to the motor by reducing the period of time that each half-cycle of the supply voltage is applied to the motor, which, in turn, advantageously reduces the losses caused by the reactive current in the less than fully loaded induction motor. At or near a full load condition, the Triac is held or latched in a conducting state to continuously apply full supply voltage to the motor.

摘要： A door operator includes a motor-driven mechanism to move a door between an open position and a closed position in response to activation of an improved control circuit. The improved control circuit includes circuitry to initialize the sequence of operation of the motor upon connection of power after installation of the door operator or upon restoration of power after a power outage. Obstruction detection circuitry is also included in the control circuit to stop or reverse the motor if the door encounters an obstacle during movement between the open and closed positions. Time delay circuitry cooperates with the obstruction detection circuitry so as to prevent stopping or reversing the motor due to the inertia of the door and of the drive mechanism as the door starts to open or close upon activation of the control circuit. During the time delay period, however, further manual activation of the control circuit is operative to stop and/or reverse movement of the door. As the door moves in one direction, movement can be stopped and restarted in the opposite direction upon consecutive manual activations of the control circuit. When the door nears the closed position, timer circuitry is activatd to energize the motor for a predetermined time or until sufficient resistance to door movement is met to activate the obstruction detection circuitry whereupon the motor is stopped. Maximum run-time circuitry is also included to set the maximum time allowable for energization of the motor to move the door in either direction between the open and closed positions.

摘要： A data totalizer for use with a fluid flow chart recorder is disclosed. The chart recorder may be for a gas well to record the flow of gas into a collection pipe and such chart recorder has a movable chart, usually a circular chart, with a first marker pen to record on the chart a static pressure within the pipe collection system and a second marker pen to record on the chart a fluid flow signal in accordance with a differential pressure across an orifice in the gas well pipe, and with first and second fluid pressure motors in the chart recorder to move the first and second marker pens. The data totalizer includes first and second linear variable displacement transformers, with linkage connected directly in the chart recorder to move in accordance with movements of the pens and connected to move the linearly displaceable elements in the two transformers. An electronic multiplier is provided to multiply together the electrical outputs of the first and second transformers to obtain a product. An electronic circuit is provided to calculate the square root of such product to obtain an electrical signal proportional to the rate of fluid flow. This signal may be multiplied by a time signal to obtain the total quantity of fluid flow, such as in cubic feet.

摘要： A phase-triggered, gate-controlled AC semiconductor switch, in series with an induction motor and its AC supply, optimizes power flow to the motor under changing mechanical load conditions by varying the amount of supply voltage applied to the motor over each half-cycle of the AC supply. Such power flow optimization is effected by utilization of a control voltage generated by the freewheeling induction motor during nonconduction periods of the switch. The triggering point of the switch relative to the preceding zero crossing point of the supply voltage, that is, the switch firing angle or delay angle, is varied by the control voltage augmenting to a varying degree the charging rate of a capacitor that triggers the semiconductor switch into conduction. Under increasing mechanical load conditions, the control voltage decreases, the decreased control voltage accelerating the charging rate of the capacitor to trigger the switch into conduction at a reduced firing angle, wherein power flow to the motor is increased. Conversely, under decreasing mechanical load conditions, the control voltage increases, the increased control voltage decelerating the charging rate of the capacitor to trigger the switch into conduction at an increased firing angle, wherein losses caused by reactive current in the less-than-fully loaded induction motor are reduced with a resultant optimization of power factor.
摘要翻译：与感应电动机及其交流电源串联的相位触发的门控交流半导体开关通过改变在每个半周期上施加到电动机的电源电压量来优化在变化的机械负载条件下对电动机的功率流的交流电源。这样的功率流优化通过利用在续流感应电动机在开关非传导期间产生的控制电压来实现。开关相对于电源电压的先前过零点的触发点，即开关触发角或延迟角，由触发半导体的电容器充电速率的不同程度的控制电压而变化切换到传导。在增加的机械负载条件下，控制电压降低，降低的控制电压加速了电容器的充电速率，从而以降低的触发角将开关触发成导通，其中提高到电动机的功率流。相反，在机械负载条件的降低下，控制电压增加，控制电压的增加使电容器的充电速度减速，从而将触发开关转变为触发角增加的导通状态，其中由小于满载的无功电流引起的损耗感应电动机减少了功率因数的最终优化。
