Abstract: RCA 72,007 Abstract of the Disclosure First l-H type comb filter provides an output representative of the sum of current line video signals and preceding line video signals, which is delivered to an adder via a wideband signal path, as a wideband combed luminance signal input occupying a given band of frequencies.  Second 1-H type comb filter provides an output representative of the difference between current line video signals and preceding line video signals which is delivered to said adder, via a signal path with a pass band restricted to only a low frequency portion of the given band, as a restricted band vertical detail signal input.  Latter signal path translates at least portions of said vertical detail signal with a gain which is enhanced relative to the gain with which said combed luminance signal components are translated by said wideband signal path, and delivers said difference representative output with such polarity that the current line video signal contribution to said difference appears at the adder with the same polarity as the constituents of the sum representative output delivered thereto.  The adder output forms a luminance signal with an asymmetrical form of vertical peaking in which overshoots only appear at transitions in the direction of vertical scanning of the black-to-white type, and undershoots only appear at transitions in the direction of vertical scanning of the white-to-black type.

Abstract: ABSTRACT OF THE DISCLOSURE        A windmill is provided for converting wind energy to reciprocal mechanical energy at a pump rod.  The windmill includes a housing having a base, a wheel shaft having a first end adapted to receive a wheel and a second end extending into the housing, and a drive gear at the second end of the wheel shaft.  A driven gear is in engagement with the drive gear and is rotatably driven thereby.  A generally cylindrical lift cam is rotatable with the driven gear, and has a generally vertical axis.  The lift cam has an edge defining a circular cam track having a rise and fall with the length of the rise exceeding the fall, the rise being rapid relative to the rise.  A walking beam is provided having one end mounted for pivotal movement and having the other end secured to the pump rod. That beam has a cam  follower thereon engaging the cam track at a substanti-ally fixed distance from the vertical axis at all positions of the follower, whereby upon rotation of the sheel shaft, gears and lift cam, reciprocating motion is imparted to the rod through the follower.  In this way upon ro-tation of the wheel shaft, gears and lift cam, reciprocating motion is im-parted to the rod through the follower and the walking beam, with a generally  linear lift being imparted to the rod and a relative fast fall in each rotation of the cam and, whereby substantially constant starting and running torque is required through a revolution of the cam.  The mill operates in wind conditions at which some conventional mills will not oper-ate.  Some pumping occurs at winds of such low velocity which in some areas renders conventional mills inoperative or not practical.

Abstract: Abstract Of The Disclosure An improved distillation method and apparatus are provided for recovering anhydrous ethanol from fermen-tation or synthetic feedstocks.  The system includes at least one stripper-rectifier tower, a dehydrating tower, and an azeotropic agent stripping tower. Substantial energy savings are realized by operating the dehydrating tower, and preferably also the azeotropic agent stripping tower, at a higher pressure than the stripper-rectifier tower and by condensing the overhead vapors from the dehydrating tower (or dehydrating tower and azeotropic agent stripping tower) to provide the heat required in the stripper-rectifier tower.  In a preferred embodiment, two stripper-rectifier towers are used, one operating at a higher pressure than the other, in which case the higher pressure tower is heated as just described and the overhead vapors from the higher pressure tower are condensed to supply the heat required in the lower pressure tower.  Further energy savings are accomplished by preheating the feedstock by means of the heat contained in the stripper-rectifier tower overhead (the lower pressure stripper rectifier tower in the case where two such towers are used) and also by the heat contained in the stripper-rectifier bottoms.

Abstract: WOUND ROTOR MOTOR APPARATUS Abstract Of The Present Invention A wound rotor motor apparatus includes an energy recovery circuit having a rectifier connecting the rotor circuit to a gated inverter having an input filter for return of rotor power to the three-phase power supply system.  A voltage chopper circuit connects the rectifier to the recovery inverter and operates to establish and maintain a constant direct current voltage to the inverter regardless of motor speed.  The voltage is greater than the line voltage and is returned at near unity power factor.  The chopper circuit is dual gated thyristors.  A first thyristor connects an inductor in series to the rectifier.  The first thyristor is turned on at the chopper frequency and current flows through the inductor.  A commutating thyristor in series with diode is connected in series with a first thyristor and a parallel and back-biasing diode.  An inductor in series with a capacitor is connected across cummutating thyristor and the inductor-capacitor junction is connected in series with a dropping resistor to the input of the inverter filter.  Upon turn-on of the commutating thy-ristor, the LC circuit tries to ring and current flows through the back-bias diode and turns the first thyristor off.  The inductor acts as a high voltage source to the inverter circuit and recharges the commutating capacitor.  When the inverter is gated on, power is returned from the constant high D.C. voltage supply to the A.C. Power supply.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to the mounting of vanes on a runnerhead of an abrasive blasting machine.  The face of the runnerhead is provided with slots in which bases of vanes are slid in a generally radial direction with  the base having an interlock with the runnerhead so as to retain the vane against movement normal to the face of the runnerhead.  This invention particularly has to do with the locking of the vane base in the runnerhead slot.  A locking  pin is used which is preferably rectangular as opposed to the usual circular pin and the outer ends of the runnerhead slot and vane base are provided with cooperating slots and grooves which receive the pin, the pin being inserted in a first groove and slot arrangement at an angle to the axis of the base and then rotated or pivoted into a second groove and slot arrangement where it is locked in place against retrieval.  The pin is locked in place by the outwardly movement of the vane from its pin inserting position.  Certain embodiments of the invention have a safety feature in when the vane is in the pin receiving position, the inner end of the vane will engage a lug case on the outside of the impeller case so as to prevent rotation of the runnerhead.
