    摘要: A coupling for causing an elevator car door to engage an elevator hoistway door includes a pair of vanes, each end of each vane pivoted on a link connecting it with the other vane, the links being disposed for rotation between said two vanes on an elevator car door thereby forming a parallelogram. The vanes extend vertically between four rollers which rotate about horizontal axles disposed at the top of the hoistway door, and which provide rotationally stiff coupling. A solenoid actuator can move one vane up to cause the parallelogram to shrink, into an uncoupled position. When the actuator is disenergized, a spring causes the parallelogram to spread so that the vanes are wedged between the rollers and the two doors are coupled together.

    摘要: An elevator car door is moved by a variable voltage, variable frequency linear induction motor which is driven open current loop to achieve a desired velocity profile indicated by an incremental linear encoder, with washed out proportional and integral gain. A magnetizing current insufficient to overcome the weight of the door is added in quadrature with the linear force current, and frequency is determined open loop in a predetermined fashion. Pulse width modulation voltage control signals are utilized to apply fixed voltages of correct polarity through a low pass three phase filter to the windings of the motor for correct intervals of time so as to synthesize desired sinusoidal winding currents. A boost of current is provided following each zero crossing of the sinusoidal winding currents to overcome lags therein. A ramp down of voltage avoids dropping the door at the end of door opening and door closing.

    摘要: The method and apparatus for generating start of combustion signals associated with the combustion events in a diesel engine (10), and for using such signals to control the timing of fuel delivery to the engine. The combustion event is sensed, as by an electrostatic (230, 330) or optical (130, 430) sensor, and signal conditioning circuitry (32) provides a start-of-combustion (SOC) signal (34) which is directly and precisely indicative of the time of the onset of combustion. The sensors (130, 230) include self-cleaning capabilities (48, 248) for extended operating life on an engine. The sensors may be incorporated in the structure of a glow plug (330, 430). The SOC signal (34) is advantageously supplied to a timing control circuit (26) which delivers a timing control signal (28) to a fuel delivery device, such as the controller (16') associated with a fuel pump (16). The control circuit (26) stores (65) one or more start of combustion values (SOC*) which indicate the desired timing, relative to an engine cycle (24), for the start of the combustion event as a function of speed (25) and load (27). One or more adjustment signals (.DELTA.SOC) are stored (75) and applied (67, 68) as a function of speed and load to adjust the desired signal (SOC*) such that the control signal (28, SOC.sub.c) is corrected for delays. The actual SOC signal (34) is compared (71) with the desired signal (66) to generate an error signal (72) which may be used to finely adjust the stored (75) .DELTA.SOC signal for particular speed and load conditions.
