Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for treating hot exhaust gas to purify the gas and/or to recover the heat values therein includes removing particulate matter from the gas, cooling the gas by transferring its heat to regenerators and purifying the cooled gas by subliming or "freezing out" harmful, less vola-tile components.  The heat energy of the exhaust gas may be recovered by passing a heat exchange medium, such as compressed air and/or purified cooled gas, through the heated regenerators.  A major advantage of this method and apparatus is that exhaust gases at 300-350°C may be purified and the heat energy recovered using thermodynamically efficient regen-erators.  As a result the air preheater stage of conventional boilers or combustion units, which com-prise 60% to 70% of the heat exchange surface area, may be eliminated.

Abstract: PIPELINED DIGITAL SIGNAL PROCESSOR USING A                COMMON DATA AND CONTROL BUS     Abstract:         A digital signal processor arranged for pipe-lined operation includes a common data and control bus and a source of instructions and data words.  An arithmetic section processes one data word with another data word through selected processing subsections performing operations according to an expression, thereby producing a resultant data word. A destination receives the resultant data word from the arithmetic section.  Control circuits receive a single normal instruction during each processor cycle for controlling all processing subsections operations. During each processor cycle, each processing subsection performs an operation relating to a different expression than the other processing subsections are performing during that processor cycle.  All of the operations controlled by the single normal instruction are executed during a single processor cycle.  The common bus is time-shared during every processor cycle for transferring the single normal instruction from the source to the control circuits, for transferring data words from the source to the arithmetic section and for transferring the resultant data word from the arithmetic section to the destination.

Abstract: Abstract High resolution, high penetration marine seismic stratigraphic system wherein a slanted cable comprising spaced-apart hydrophone arrays gather seismic reflections so that the corresponding primary and ghost reflections from a common interface gradually are spaced apart.  The primary reflections are time aligned and stacked.  The ghost reflections are phase reversed, time shifted and time aligned to coincide with the time aligned primary stack and then stacked to give a combined primary and ghost stack, which effectively includes almost twice the information as from the primary stack alone.  No inverse notch filters are needed to correct for the ghost phenomenon.  Focused noise out of the vertical plane is also virtually eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention is directed to a cutterhead for a portable power planer. The cutterhead includes a cylindrical body having a substantially cylindrical surface and defining a rotational axis about which the cylindrical body rotates during normal operation of the power planer.  A solid elongated cutting member is provid-ed and has a channel formed therein to define at least two cutting edges.  The cylindrical body has an elongated recess formed therein for holding the cutting member.  The recess extends in a direction parallel to the rotational axis of the cutterhead and defines a longitudinal aperture in the surface for accommodating one of the cutting edges. The recess has a recess wall extending inwardly away from the aperture to surround and hold the cutting member against the centrifugal forces acting thereupon during the rotation of the cylindrical body.  Positioning pins arranged in the cylindrical body engage the cutting bar to angularly fix the cutting member so that the one cutting edge penetrates the aper-ture at a predetermined angle of elevation with respect to the surface of the cylindrical body. A screw mounted in the cylindri-cal body directly engages the cutting member to tightly seat the latter against the recess wall.

Abstract: BI- DIRECTIONAL CLUTCH                     Abstract of the Disclosure There is disclosed a bi-directional clutch, part-icularly useful in window shade applications.  The bi-directional clutch includes a first or core member and an unwrap spring, that is, a spring having an inside diameter somewhat smaller than the diameter of the core, the spring being wound around the core.  The unwrap sprinq has a number of helical turns and spring tangs which extend outwardly past the circumference of the spring and generally perpendicular to the axis of the spring.  The spring is controlled by a second control or driving member which, when rotated, applies force to one or the other of the spring tangs to unwrap or loosen the spring, thereby allowing the spring to rotate relative to the core.  As the spring rotates, one of the spring tangs abuts a third or driven member.          The third or driven member is rotated by the spring, allowing the third member to rotate relative to the first or core member.          The third or driven member continues to rotate, relative to the first or core member, until the second, control or driving member stops rotating.  However, when the driven member is rotated directly, the spring is locked onto the core member and further rotation of the driven member is prevented.         According to a first embodiment of the invention, the spring tangs of the unwrap spring are crossed-over, the second, control or driving member has a U-shaped channel which abuts either of the outer surfaces of the spring tangs as the driving member rotates, and the third or driven member has a rib, located between the spring tangs, which is abutted by the inner surface of the spring tangs to transfer rotation from the driving to driven member.  In a second embodiment, the spring tangs of the spring are not crossed-over, the second, control or driving member has a rib located between the inner surface of the spring tangs, and the third or driven member has a U-shaped channel which is moved by the outside surface of the spring tangs to transfer rotation from the driving to driven member.  When the bi-directional clutch is used as part of a window shade mechanism, the first or core member is held stationary.by attachment to a bracket which is affixed to a window frame, the third or driven member is fixedly attached to a window shade, and the second,control or driving member is turned in a clockwise or counterclockwise direction by a window chain or cord, to either raise or lower the shade.
