Abstract: ABSTRACT OF THE DISCLOSURE        An elevator system having a plurality of elevator cars and supervisory control for directing their movement in a building to efficiently serve the floors therein.  The supervisory control divides the work load uniformly among the elevator cars by periodically assigning, clearing and reassigning service directions from the floors to the cars according to a predetermined strategy.  The predetermined strategy accords special treatment for assigning the service directions from floors at which each oar will stop and depart in a predetermined direction due to register car calls.  The strategy includes special limitations on such car call related assignments to improve elevator service, with one embodiment limiting such car call related assignments to a predetermined number N, which are the N closest car calls ahead of the car.  Another embodiment provides a dynamic limitation on car call related assignments by count-ing the stops due to car calls and previously committed hall calls ahead of each car, and making a car call related assignment only when it is within a predetermined number of stops ahead of the car.                BACKGROUND OF THE INVENTION U.S. Patent 4,046,227 issued September 6, 1977 to A. F. Kirsch et al; U.S. Patent 4,037,688 issued July 26, 1977 to C. L.

Abstract: ABSTRACT OF THE DISCLOSURE             A valve actuator for an expanding gate valve having a gate and a segment thereon.  The actuator includes a piston connected to a gate stem and mounted within a cylinder with a pressurized gas on the upper side of the piston and liquid on the lower side of the piston.  The gate valve moves from an open position to a closed position across the flow passage at a rapid rate and decelerates adjacent the end of its downward movement upon a metering of the liquid in the cylinder.  The expanding gate valve expands laterally into fluid-tight sealing relation at the end of the downward stroke after moving across the flow passage.  The bonnet is mounted internally of the valve body and a pressure seal is positioned between the bonnet and the valve body to permit operation of the valve actuator and gate valve even after failure of the pressure seal.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention concerns a means of providing tertiary treatment to incoming raw sewage to the septic tank. This is accomplished by providing an improved type sewage treatment container having three tertiary treatment chambers. In a first treatment chamber an artifial turbulent area is created containing therein a quantity of selected sorptive coal fines. Incoming raw sewage if directed towards the turbulent area wherein it is intermixed with the sorptive coal fines. Periodically the eff-luent from the first chamber is passed into the second chamber wherein second stage sedimentation occurs. The effluent from the second chamber is then passed into a third sedimentation chamber wherein third stage sedimentation occurs, the settled sludge from the third sedimentation chamber is passed by means of a steeply sloped floor down through an opening in the lower portion of the second and third divider wall of the sedimentation chambers, the effluent from the said third sedimentation chamber is then discharged as treated effluent by the outlet means to surface waters.

Abstract: ABSTRACT OF THE DISCLOSURE      A control circuit for controlling selected functions in a signal receiver, such as a television receiver, in response either to remotely generated control signals of different selected frequencies or to manual controls which are provided on the signal receiver.  The control circuit comprises an integrated circuit having a first input for receiving the remotely generated control signals.  A frequency discriminator is included in the integrated circuit to detect the frequency of a signal applied thereto and to produce corresponding function control signals. A variable oscillator, also included in the integrated circuit, selectively generated local control signals of substantially the same different selected frequencies as the remotely generated control signals.  A mixing circuit supplies the received remotely generated control signals or the local control signals to the frequency discriminator.  A frequency control circuit, external of the integrated circuit and coupled to the manual controls, produces a variable frequency-control signal as a function of the operation of the manual controls.  A second input provided in the integrated circuit connects the frequency control circuit to the variable oscillator, whereby the frequency of the local control signal generated by the variable oscillator is determined by the frequency-control signal produced by the frequency control circuit connected thereto.     -i-

Abstract: ABSTRACT There is disclosed herein a programmable cardiac pacemaker pulse generator utilizing digital circuitry for controlling the provision of card-iac stimulating pulses.  The pulse generator is capable of having the rate, the pulse width, the pulse amplitude, the refractory period, the sensitivity and the mode of operation programmed.  In addition, the pulse generator can have the output inhibited and can respond to programming signals causing a threshold margin test to be performed, effects of closure of the reed switch overridden, a hysteresis function added and a high rate exceeding the normal upper rate limit programmed.  Many of the programmable functions of the pulse generator can either be programmed on a permanent or a temporary basis.  The pulse generator further includes means for signaling the accept-ance of a programming signal, and means to reset the program acceptance cir-cuit if extraneous signals are detected as programming signals.  The program signal acceptance circuit performs several different checks on the detected programming signal including a parity check, an access code check and deter-mining if the proper number of signals were transmitted within a given time. The timing circuit of the pulse generator includes a crystal clock oscilla-tor and counter means for counting the clock pulses therefrom to determine the rate of the pacemaker.  The pulse width of each pacemaker pulse is de-termined by using a voltage controlled oscillator in place of the crystal oscillator to obtain energy compensation due to the battery voltage decreas-ing with time.
