Abstract: METHOD OF OPERATING A BLAST FURNACE TO EXTRACT CARBONACEOUS OIL AND GAS      FROM BITUMINOUS MATERIALS          ABSTRACT A blast furnace is employed to process a natural material selected from the group consisting of oil shale, oil sandstone, asphalt rock or mixtures thereof. A first carbonaceous material selected from the group consisting of oil shale, oil sandstone, asphalt rock or mixtures thereof and a second carbonaceous material are charged to the top of a blast furnace and the carbonaceous char material remaining when the burden reaches the lower portion of the blast furnace in front of the primary tuyeres is burned to provide a hot, upwardly-moving gas stream containing CO and H2 to vaporize recoverable hydrocarbons contained in the carbonaceous material as the carbonaceous material moves downwardly through the blast furnace. A gas containing hydrocarbons, CO, H2 and vaporized carbonaceous oil and tar is withdrawn from near the top of the blast furnace and a molten slag is withdrawn from near the bottom of the blast furnace. The off gas can be condensed to provide liquid oils and a gas having a desirable Btu content. Provision is also disclosed for the removal of alkali metals from the process.

Abstract: Abstract of the Disclosure To overcome the problems in prior electret devices resultant from non-uniform distribution of the surface potential on the electret there is provided a method for manufacturing an electret device in which a DC voltage is applied by a power applying circuit across metal layers on both surfaces of a dielectric material film.  The power applying circuit is then opened, while the DC voltage is being applied, to stop applying the DC voltage, thereby obtaining an electret in which the surface potential is well controlled in correspondence with the applied voltage.  Also disclosed is a condenser type electro-acoustic transducer having reduced high harmonic distortion, this transducer having electrets as the stationary electrodes which are provided by the above method.

Abstract: ABSTRACT           There is disclosed an airplane having an inflatable type air cushion confining undercarriage thereunder wherein the airplane wing structures comprise three-dimensionally enlarged inner wing components merging aerodynamically with the airplane fuselage.  The under surfaces of the inner wing components and the fuselage cooperate to provide a downwardly convex broad base structure which is oval-shaped in planform, and a toroidal configured inflatable trunk is attached to the perimeter of the base structure for circumscribing the air cushion cavity under the airplane.  Thus, an enlarged width and length air cushion type undercarriage is provided to give the airplane improved stability characteristics when operating in air cushion, ground, or water supported mode.  When the trunk system is deflated the elastic sheet material thereof retracts snugly against the slightly convex bottom surface of the base structure.

Abstract: FILM FILL SHEETS FOR WATER COOLING TOWER HAVING INTEGRAL SPACER STRUCTURE     Abstract of the Disclosure An improved, self-positioning, synthetic resin, multiple-sheet fill structure for cooling towers is provided which preferably includes upright, thin fill sheets having elongated, out-wardly extending, hollow, cooperable indexing units thereon; the respective indexing units are strategically located and arranged such that opposed units on adjacent sheets are transversely disposed relative to one another and telescopi-cally interengage with two point contact.  This construction minimizes sheet warpage while in-creasing the load and deflection resistance of the fill structure.  Preferably, the indexing units are of outwardly tapered configuration and present arcuate, opposed end segments separated by recess-defining walls; inwardly extending bottom walls connected to the recess-defining walls serve as spaced abutment surfaces extending into the hollow regions defined by the units for engaging the associated units on adjacent fill sheets.  The indexing units are advantageously arranged in upright columns and horizontal rows on the sheets in such manner that the longitudinal axis of each respective unit is transverse to the longitudinal axes of the next adjacent units in the column and row in which the respective unit belongs.

Abstract: EDDY CURRENT TESTER                 ABSTRACT OF THE DISCLOSURE         An Eddy Current Tester for Detecting defects in conductive materials employs phase rotation curcuitry for eliminating the effects of lift-off signals from the reactive component of the output of an eddy current probe.  An operator digitally selects a frequency which is input to the eddy current probe which is adjacent a test material.  The signal output from the eddy current probe is amplified and demodulated into reactive and resistive components which are processed by phase rotation circuitry.  The phase rotation circuitry is calibrated by applying a lift-off signal thereto while a phase adjust switch is on.  When the phase adjust switch is on the reactive signal component is applied to a zero crossing detector which in conjunction with a flip flop controls the counting direction of an counter which addresses a sine-cosine table in a erasable programmable read only memory.  The sign-co-sine values are strobed into a latch which provides the sine-cosine information to multiplying curcuits which multiply the reactive and resistive signal components output of the demodulator by the sine and cosine stored in the latch.  The outputs of the multiplying curcuit are input to a phase rotator which outputs signals which are rotated in the complex plane by the angle corresponding to the sine and cosine stored in the latch.  While the phase adjust switch is on, the reactive component of the output of the phase rotator hunts about zero.  When the phase adjust switch is off, the phase rotator rotates the phase of any signal input into the multiplying circuitry by the angle indicated by the last sine and cosine values strobed into the latch.

Abstract: ABSTRACT A remotely controlled, adjustable stroke fluid power actuator system includes a cylinder having opposite end walls and a piston rod slideably extending through one of the end walls, the piston rod having a passage extending between its interior and exterior portions. A captured piston is secured to the interior portion of the piston rod and a floating piston is movable between a position abutting the captured piston and a position spaced therefrom. The pistons define a cavity therebetween, the passage in the piston rod com-municating therewith. The cylinder has a first port for admitting fluid between the one end wall and one of the pistons to move at least one of the pistons in one direc-tion toward the other end wall, and a second port for admitting fluid between the other end wall and the other of the pistons to move at least one of the pistons in the opposite direction toward the one end wall. The exterior portion of the piston rod has a third port for admitting fluid to the passage and cavity thereby to move one of the pistons away from the other. A manually-activated, four-way valve selectively connects a fluid pump to the first cylinder port and to the second or third cylinder ports as determined by a solenoid-actuated two-way selector valve.
