Abstract: ABSTRACT      An alignment and exposure system is provided with a main stage for positioning a reference mark or a semicon-ductive wafer directly beneath a projection lens.  The reference mark is mounted on the main stage by a substage permitting the reference mark to be positioned in alignment with the axes of motion of the main stage and in a plane parallel to and coincident with the image plane of the projection lens.  Selected portions of a reticle disposed above the projection lens on another stage may be illuminated with either exposure or nonexposure light by a controllable light source unit.  While employing the projection lens and a first objective lens unit to view images of portions of the reference mark or wafer illuminated by projected images of the illuminated portions of the reticle, the main or other stage may be employed to directly align the wafer with respect to the reticle or the reticle with respect to the reference mark.  While employing a second objective lens unit to view images of portions of the wafer illuminated by projected images of a pair of prealignment reticles, the main stage may be employed to align the wafer with respect to those reticles.

Abstract: Abstract of the Disclosure Novel nonlinear optical, piezoelectric, pyroelectric, waveguide, and other materials are presented together with processes for their employment and articles formed thereby.  Such materials, processes and articles comprise diacetylenes and polymers formed from diacetylenic species, which polymers are amenable to close geometric, steric, structural, and electronic control. Accordingly, it is now possible to design, formulate and employ new diacety-lenic species and polymers formed therefrom to provide nonlinear optic, wave-guide, piezoelectric, and pyroelectric materials and devices having surprising efficiencies and degrees of effect.  The diacetylene, i.e. acetylenes with at least two acetylenic bonds, are preferably crystallizable into crystals having a noncentrosymmetric unit cell.  They may form single crystals or may be elaborated into a thin film upon a substrate by the Langmuir-Blodgett technique. Such films may, optionally, be polymerized either thermally or by irradiation for use in nonlinear optical and other systems.  According to other preferred embodiments, diacetylenes are covalently bonded to substrates through the employment of silane species and subsequently polymerized to yield nonlinear optic and other devices having high structural integrity in addition to high efficiencies and effects.

Abstract: IN THE UNITED STATES PATENT AND TRADEMARK OFFICE     Inventors:   Karim ZAHEDI and Jeffrey C. ALEXANDER            Title:       FILTER APPARATUS AND METHOD FOR       COLLECTING FLY ASH AND FINE DUST     Abstract of the Disclosure Fly ash and fine dust in a gas stream from a coal combustor, for example, are efficiently collected in a 2-stage, tubular, granular bed filter.  The stages of the filter are arranged one above the other so that the gran-ules may move from the upper stage to the lower stage under the influence of gravity.  Larger particulate in the gas stream is first collected by the lower stage, and then the remaining particulate is electrically charged and col-lected by the upper stage.  Both stages are electrified sufficiently to rigidify the granular beds and adhere the particulate to the granules, so that the granules and the collected particulate move downwardly through the filters as a plug.  Granules that exit from the lower stage are cleaned and returned to the upper stage.  Non-porous granules may be used to prevent fine particulate from be-coming embedded in the granules.

Abstract: ABSTRACT The present invention relates to a wind powered generator mechanical arrangement and control.  The generator comprises a propeller having a directly coupled rotating field comprising permanent magnets mounted in a rotating housing.  The stationary armature in turn is supported on a suitable tower support and is mounted to permit it to rotate about a vertical axis to permit the propeller to be properly oriented with respect to the direction of the wind.  On the opposite side of the vertical mounting axis from the propeller a suitable control and counterweight arm is mounted providing a balanced support for the generator.  A vane or tail is mounted for pivotal movement about a vertical axis relative to the counterweight arm, and its angle relative to the counterweight arm and relative to the axis of rotation of the propeller can be varied in response to certain parameters that are being sensed.  The vane controls the position of the propeller axis relative to the wind and thus may prevent excessive current from being generated; prevent overspeed; prevent overcharging storage batteries, if such are being used, and prevent the unit from providing excessive charging current.

Abstract: ABSTRACT              An echo canceller is connected between two trans-mit and receive paths, respectively, which are coupled to a two way path. This echo canceller is arranged for can-celling a variable phase echo signal occurring in the receive path and comprises an adaptive filter connected to the transmit path and a circuit for forming a difference signal between a signal supplied by this filter and a signal in the receive path.  If ?(n) i a simulated phase of the echo signal at an instant nT, the echo canceller of the invention comprises either a phase shifter for changing over a phase angle ?(n) the phase of the complex signal formed in the receive path, or a phase shifter for changing over a phase angle ?(n) the phase of the complex signal supplied by the filter. The coefficients of the filter and of the simulated phase ?(n) are controlled together for minimizing the mean square value of the residual echo present in the difference signal. This echo canceller is used for data transmission over two-wire circuits.

Abstract: IDENTIFICATION STRIP ASSEMBLY   AND METHOD OF USE THEREOF                             Abstract An identification strip assembly especially adapted for use with tubular insert-receiving identification bands, such assembly taking the form of a base strip and an over-lying cover strip.  The base strip includes handle, insert, and tip sections delineated by transverse lines of perforation.          The cover strip is secured only to the handle and tip sections of the base strip, is transversely perforated along a line disposed above the boundary between the handle and insert sections of the base strip, and is provided with means for producing an image on the insert section when such section, and the portion of the cover strip above it, are subjected to compressive force.  The perforation lines are formed to tear or break preferentially so that when a user grips the assembly to snap the tip and handle sections apart, two of the perforation lines will break simultaneously to disconnect the insert section from its cover and from the tip section while leaving the insert section still attached to the covered handle section.  Following insertion of the insert section into a tubular identification band, the user may then snap the handle and insert sections apart to break the remaining perforation line.

Abstract: Abstract of the Disclosure The present invention is directed to microporous mem-branes having a surfactant impregnated therein which is coated on at least one surface thereof with a polymer coating, such as cellulose acetate.  The polymer coating possesses functional groups in the presence of an aqueous alkaline environment which permits it to undergo hydrogen bonding with water and to transport battery electrolyte through the coating by diffusion.          The presence of the coating on the normally hydrophobic substrate membrane, when used in conjunction with a suitable surfactant, increases the wettability of the substrate membrane and thereby lowers its electrical resistance.  The coating also serves to immobilize various soluble electrode derived ions at the coating-electolyte interface thereby hindering their penetration into the pores of the substrate microporous membrane.  Consequently, the plugging of the pores of the substrate membrane by these ions is substantially reduced thereby increasing the life of a battery in which said coated membranes are used as battery separators.

Abstract: Abstract of the Disclosure High melt flow olefin polymers suitable for such applications as injection molding, and the like requiring a narrow molecular weight distribution are produced using a catalyst made by reducing and reoxi-dizing a chromium catalyst on either a titanium-silica cogel or a self-reduced silica-containing composition.  In the first embodiment, a cogel formed by coprecipitating silica and titania, and containing a chromium compound, is treated in a nonoxidizing atmosphere, such as CO, hydrogen, N2 or a material decomposable to these materials, and thereafter reoxi-dized.  In the second embodiment, a titanium-free chromium containing catalyst is first heated in air or the like to dry the catalyst and oxidize the chromium after which it is heated in an inert atmosphere wherein the composition is self-reduced to give chromium in a lower valence state.  The resulting self-reduced composition is then heated in a reducing ambient and then reoxidized as in the first embodiment.
