Abstract: DEFLECTION SYSTEM WITH OVERSCAN PROTECTION        Abstract of the Disclosure In a deflection system including an oscillator and an amplifier providing scanning current for a deflection winding, a parabolic voltage developed at the deflection winding is superimposed on the oscillator direct current operating voltage in such a proportion that an increased parabolic voltage level, indicative of excessive scanning current from either an overscan or low operating frequency condition, causes the oscillator to operate at a higher frequency which decreases the deflection winding current and therefore the parabolic voltage and thereby permits the use of less expensive circuit components having lower maximum voltage level ratings.

Abstract: ABSTRACT OF THE DISCLOSURE           In a facsimile system, rotation of a transmitter drum carrying a document is synchronized with the rotation of a receiver drum carrying a copy medium.  Synchronization of the rotating transmitter drum and the rotating receiver drum is assured by driving the transmitter drum from an AC power line and locking the receiver drum to the AC power line frequency once synchronization of the transmitter drum and the receiver drum have been achieved.  In order to achieve initial synchronization, the drive for the receiver drum is initially locked to a source of controlled frequency until a predetermined angular position of the receiver drum relative to a predetermined angular position of the transmitter drum is attained.  The receiver motor which is of the DC type is controlled in angular frequency after initial synchronization by generating a signal having a frequency phase locked to the AC power line frequency.

Abstract: RESPIRATOR PRESSURE-DEMAND EXHALATION VALVE           Abstract of the Disclosure A chamber in a valve case has an inlet port for ex-haled air in one of its end walls.  Spaced inwardly from the side wall of the chamber is a valve seat surrounding the inlet port and engaged by one side of a sealing member, the opposite side of which is engaged by a rigid disc secured to a valve stem that extends through the port and into guiding means for the stem.  The diameter of the disc is nearly as great as the diameter of the chamber.  A spring in the case is compressed between the disc and the other end wall of the valve chamber for pressing the sealing member against the seat.  The disc is spaced from the ported wall of the chamber far enough for the marginal portion of the disc that extends laterally out beyond the sealing member to be inclined toward the ported wall but spaced from it.  The side wall of the chamber is pro-vided with exhaust slots extending around the disc and having inner walls adjacent the ported wall lying in a plane substan-tially coinciding with the plane in which lies the edge of the disc, and the space between the valve seat and the side wall of the case is always open to the slots.

Abstract: ABSTRACT OF THE DISCLOSURE A process for separating hydrocarbon gases is described for the recovery of gases such as ethane and heavier hydrocarbons from natural gas streams or similar refinery or process streams.  In the process described, the gas to be separated is cooled at a high pressure to produce partial condensation, and the vapor and liquid portions are separated.          Liquid from the partial condensation is further cooled and then expanded to a lower pressure.  At the lower pressure, the liquid is supplied to a distillation column, wherein it is separated into fractions.  The vapor portion is work-expanded to the operating pressure of the distillation column and supplied to the distillation column below the feed point of the expanded liquid portion. The operating efficiency of the process is improved by turning back at least part of the vapor portion and warming it by heat exchange against incom-ing feed before it is work-expanded.  By thus warming the vapor, more work and refrigeration can he recovered in the work expansion machine.

Abstract: DEMAND/SCHEDULE CONTROLLER             Abstract of the Disclosure A demand controller includes a microprocessor which is programmed to input data from switches on a control panel and output data to a set of eight circuits which control the operation of loads.  Peak power demand is maintained below a preset DEMAND          OBJECTIVE by selectively shedding these loads.  The shed level for each load is not fixed, but instead, varies as a function of the rate at which total power demand is increasing.  This rate is calculated by the microprocessor and the resulting shed level index (i) is employed to select the proper shed level for each load from a stored shed level matrix.

Improved vehi-cle speed-limiting and stopping circuits control truck operation in accordance with computed heading and lateral displacement deviations independently from each other. Steering systems are illustrated both for vehicles using steerable wheels and vehicles steered by differential drive wheel speed control.

Abstract: ABSTRACT             A color coding system for correlating the stages of a multiple stage, telescoping boom with the corresponding sec-tions of a load chart and boom extension chart.  The charts are arranged in separate sections which indicate, for various posi-tions of the boom, the angle of the boom wire respect to hori-zontal, its effective horizontal length, and the maximum load that it can safely handle.  The boom stages are each provided with a different exterior color, and the chart sections are colored such that each section is correlated with the boom stage to which it corresponds.  Since the colors of the boom stages that are extended are readily visible, color coding system facilitates reference to the proper sections of the charts and decreases the possibility of human error in reading of the charts.
