Abstract: This invention relates to an improved sliding entrance door assembly for an elevator and to the method of installing the assembly. In one embodiment the assembly includes one or more stationary panels affixed to the frame. The stationary panels are comprised of a side panel and a transom panel. The side panel replaces the wall adjacent to the elevator opening. The transom panel is located above the sliding entry door and the side panel. By using the stationary panel, which is thinner than a conventional wall, the sliding entry door assembly uses less of the hallway space. In an alternate embodiment, two sliding entry doors are installed in the frame. They are in separate planes so that one door can slide behind the other. The advantages to the present door assembly is that it may be installed in less time and the assembly requires less space than conventional door assemblies. Also the assembly closes the gap to the shaftway as soon as it is installed.

Abstract: This invention relates to an improved sliding entrance door assembly for an elevator and to the method of installing the assembly. In one embodiment, the elevator sliding entrance door assembly comprises, viewed from the hallway, a sill, a left vertical post having a top portion, a right vertical post having a top portion and positioned parallel to the left post, a header formed with an open notch connected to the left and right posts, a door frame consisting of a strike jamb, head jamb and return jamb attached to the header, one post and sill. An elevator door track is attached to the header. The assembly also includes a sliding elevator door having rolling means to rollingly suspend the door from the track, the door being adjustable after being suspended through the opening formed in the header. In addition, the slide sill having a groove therein which defines a lower track for the door extends between the left post and the right post.

Abstract: A microwave oscillator is shown to include an oscillator having an output and a control port and a feedback circuit disposed between the output and the control port of the oscillator. The feedback circuit includes a modulated laser, having an input and an output, the input responsive to a portion of a signal from the output of the oscillator and a photo detector having an input and an output, the input of the photo detector responsive to a signal from the output of the modulated laser delayed by a predetermined amount of time. The feedback circuit further includes a detector having a first and a second input and an output, the first input of the detector responsive to a signal from the output of the photo detector, the second input responsive to a portion of the signal from the output of the oscillator shifted in phase to be in phase quadrature with the signal at the first input of the detector and the output of the detector coupled to the control port of the oscillator.

Abstract: An oscillator includes an amplifier having an input and an output and a feedback circuit disposed between the input and the output of the amplifier. The feedback circuit includes a plurality of resonators and a pair of switches. Each switch includes a first port and multiple connectable ports, the multiple connectable ports of each switch connected to a corresponding one of the plurality of resonators. The feedback circuit further includes a voltage-controlled phase shifter disposed in series with the switches. The oscillator further includes a discriminator circuit, responsive to signals from the feedback circuit, for providing a control signal to the voltage-controlled phase shifter for degenerating low frequency noise within the oscillator. With such an arrangement, high Q low noise resonators can be switched in and out of the circuit thus providing improved phase noise performance at high power levels with the desirable frequency agility required for a microwave oscillator.
