Abstract: Abstract A digital electron optics correction circuit for correcting the focus and astigmatism in a displayed image on a CRT is disclosed.  The circuit includes a clock generator for generating a selected number of pulses between each horizontal blanking synchronization pulse.  These clock pulses are then counted by an X-address counter and a first address signal is generated corresponding to a particular horizontal position on the CRT screen for each count of the X-address counter.          A pulse generator circuit is also provided which is coupled to receive the vertical blanking synchronization pulses and which provides a selected number of output pulses for each vertical blanking synchronization pulse.  A Y-address counter counts the output pulses from the pulse generator circuit and provides a second address signal corresponding to a particular vertical position on the CRT screen for each count.  These X- and Y-addresses are then input to focus and astigmatism ROMS which are preprogrammed with an appropriate control correction signal for each X-Y-address.  In a first embodiment of the invention, the pulse generator circuit includes a dividing circuit which is coupled to receive the horizontal blanking synchronization pulses.  The dividing circuit then provides an output pulse for every N2 pulses received, and each such output pulse is then utilized to increment the Y-address counter.  In a second embodiment, the pulse generator circuit includes a second clock generator for generating N3 pulses between successive vertical blanking synchronization pulses, with each clock pulse being used to increment the Y-address counter.  Also disclosed is a specialized clock generator circuit for generating a preselected number of pulses between successive gating pulses.

Abstract: Abstract:                         AIR FLOW SENSOR      An air flow sensor (10) as may be used to measure input air to an internal combustion engine has an aero-dynamically designed impact tube (16) for diverting by-pass air to a pair of sensors (28, 30).  Downstream from the impact tube (16) is a venturi section providing ex-haust means for the bypass air.  The exhaust path con-figuration for the bypass air shields the sensors  (28, 30) from a reverse pressure wave which can result from an engine backfire.   The impact tube  (16)  operates to integrate the air velocity over a full radius of the air flow body (14).                         (FIGURE 1)

Abstract: AUTOMATIC DISPENSER FOR DISINFECTANT                  AND BOWL CLEANING FLUID            ABSTRACT OF THE INVENTION        An automatic dispenser for disinfectant and bowl cleaning material adapted to be suspended stationarily in the tank of a flushing bowl wherein the dispenser comprises a container with ball valve floated against the tapered in-terior of an upper opening in the container and an adjust-able drainpipe in the bottom of the container with the ad-justable drainpipe having an upper tapered opening and a ball valve for closing the same as well as lower openings extending downwardly outside the container providing pass-age for container water or tank water as the case may be.         In operation the two ball valves are floated to the top of their respective openings sealing the openings and isolat-ing the water in the dispensing container.  The dispensing container is provided with preferably a block of soluble disinfectant cleaning material such as a hypochlorite which will dissolve very slowly into the water in the container.          When the tank is flushed, the water level in the container drops together with the water level in the tank thereby displacing the container and drainpipe ball valves allowing the disinfectant solution to be dispensed.  The disinfec-tant solution flows out through the drainpipe, and openings in the drainpipe extending below the lower level of the container, into the tank and eventually to the bowl.  When the flushing operation is finished, the rising of the water ABSTRACT OF THE INVENTION (cont'd.) in the tank permits the ball valves to close.  No water is dispensed into the tank water at the beginning of the re-filling of the tank.  The drain ball-valve rises with the rising tank water, eventually fitting tightly to the tap-ered opening.  Then, tank water on the outside rises until reaching the upper opening.  The device is refilled with fresh tank water until the ball stop closes the upper open-ing.  No mechanical or other operating devices are required other than the two floating ball valves and the operation of the device is entirely in response to the flow of water into and out of the toilet tank so that the operator need not even be aware that a dispensing device is located and operating therein.

Abstract: ABSTRACT     A multi-bladed propeller and shaft assembly is provided in which air can be fed to the propeller blades to reduce the effects of cavitation.  A shaft leads to a multi-bladed propeller and carries a sleeve  formed with inlet passages and axial and radial passaqes leading to the respective blades.   A slip ring supported in an anti-rotation device allows the shaft sleeve to rotate within axially spaced bearings of the slip ring.  Axially spaced air seals together define with the body of the slip ring an annulus within which inlet passages rotate.  Each seal is  formed  as  a  multiplicity of  arcuate  segments resiliently biased towards the sleeve and having movably sealed end face portions to maintain pressure tightness.          The body further has a radial flow passage for admission of air under pressure to the annular space and a flexible fluid connector connects the radial flow passage to an air supply line leading from the hull structure.  The present shaft delivery slip ring avoids the need to feed air down the whole length of the propeller shaft or to feed air into the hub through a slip ring making wiping contact with the hub, which is structurally more complex.

Abstract: TURF AERATING APPARATUS            ABSTRACT OF THE DISCLOSURE           A turf aerator includes a wheel-supported frame and drive means for propelling the frame across the ground at a predetermined rate.  A pair of substantially vertical tine arms each having a plurality of downwardly directed turf coring tines attached to the lower end thereof are mounted on the frame for alternate penetrating engagement with the ground.  A tine arm actuating mechanism produces an essen-tially elliptical movement of the upper end of each tine arm, the major axis of the elliptical movement being substantially vertical.  A rocker mechanism indirectly connects the lower end of one tine arm with the lower end of the other tine arm such that the horizontal movement of one tine arm with respect to the frame upon engagement of that tine arm with the turf produces an equal and opposite horizontal movement of the other tine arm and vice versa.  The aerator produces a sub-stantially vertical insertion and withdrawal movement of the tines and a resultant minimal disturbance of the surrounding turf area.

Abstract: FOR FOSSIL FIRED BOILER                  ABSTRACT OF THE DISCLOSURE    Apparatus and method for the efficient and economic removal of sulfur dioxide from gases, in which the gas is contacted with neutralizing values obtained from pressure hydrated lime or pressure hydrated dolomitic lime, i.e. calcined limestone or dolomite and slaked with water under elevated temperature and pressure.  The pressure hydrated lime or dolomitic lime may be used in conjunction with a wet scrubber, in a spray dryer or dry scrubber, or directly introduced into the gas passages of a boiler, upstream or downstream of the air preheater, or in the boiler output ducting or the inlet of an electrostatic precipitator.  The use of pressure hydrated lime or pressure hydrated dolomitic lime greatly enhances the efficiency of sulfur dioxide removal, thereby providing for enhanced use of base values and a more rapid rate of reaction.  The confined zone dispersion scheme permits a partial SO2 removal (10%-50%) without a scrubber, only by atomizing a slurry of pressure hydrated lime or pressure hydrated dolomitic lime into the flue gas duct of the boiler.
