Abstract: ABSTRACT   Polyester polyols are prepared by the reaction of a polycarboxylic acid or anhydride with a polyhydric alcohol employing in an initial step a stoichiometric excess of poly-carboxylic acid or anhydride, thereafter removing between 90% to 95% of the water of esterification, adjusting the stoichiometry of the reaction by addition of polyhydric alcohol, and continuing the esterification reaction until a polyester polyol having an acid number of less than two is obtained.  The process allows for an increase in reactor capacity without equipment modification at the same cycle times and a decrease in side product formation.

Abstract: "IMPROVED SKID CONTROL SYSTEM"            Abstract:          A skid control system is provided for use with a vehicle having at least first and second spaced apart, independently rotatable wheels and having a braking system for applying braking forces to the wheels.  A brake control device responds to an applied skid signal for controlling the braking system to release the braking forces on the wheels.          A first logic circuit provides a skid signal when a predetermined percentage of the magnitude of a high wheel speed signal, representative of the faster of the two wheels, differs from that of a low wheel speed signal.  Another logic circuit provides a skid signal when the acceleration of the faster wheel exceeds a reference acceleration level.  An enabling circuit passes this skid signal only if the other logic circuit has provided a skid signal.

Abstract: METHOD AND SYSTEM FOR EFFECTING CONTROL         GOVERNING OF A STEAM TURBINE     ABSTRACT OF THE DISCLOSURE         A method and system for effecting control governing of a steam turbine wherein the steam chamber of a first stage nozzle is divided into a plurality of steam compartments, control valves each connected to one of the steam compartments are individually operated for controlling the flow rate of steam introduced into the turbine, and the governing of the nozzle is effected by adjusting the flow rate of steam in accordance with a load.  At low load, the degree of opening of the control valves is kept constant and the turbine is driven by steam of a reduced pressure by reducing the pressure of the steam at the inlet of the turbine so as to maintain, in a low load region, the volume flow rate of steam for a high load region.  To cope with a change in the value of the load, the degree of opening corresponding to a predetermined change in the value of the load is set beforehand for each control valve.  When the change in the value of the load is smaller than the predetermined change in the value of the load, the degree of opening of the control valve involved is adjusted.  Conversely, when the change in the value of the load is greater than the predetermined change in the value of the load, the pres-sure of the steam at the inlet of the turbine is controlled.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to instantaneous monitoring of information recorded on a videodisc.  In the prior art, it has not been possible to accurately determine the quality of a recorded videodisc until after completing the recording process.  The present invention overcomes this problem by providing an im-proved apparatus and method for instantaneously checking information recorded on a videodisc.  In accordance with the invention, the instantaneous monitoring system includes a comparator for comparing a video output information signal developed from reading a videodisc with a video input signal used to write information on the videodisc.  Further included is an F.M. modulator for converting the voltage varying with time signal to a frequency modulated signal.  A writer is provided for storing the frequency modulated signal upon a light responsive videodisc in the form of alternate regions of high and low directional reflectivity normal to the surface of the disc.  A sensor, responsive to the reflected light, is used for recreating the frequency modulated signal, and a modulator responsive to the output of the sensor produces a voltage varying with time output video information signal.  The comparator output is used to verify the quality of the information being stored on the videodisc.
