Abstract: D21,849 METHOD AND APPARATUS FOR CONVERTING BINARY     INFORMATION INTO A HIGH DENSITY SINGLE-SIDEBAND SIGNAL by A. Lender and H. H. Olszanski ABSTRACT OF THE DISCLOSURE        An incoming bit stream is digitally processed to obtain both in-phase and quadrature-phase 7-level correlative signals.         The two 7-level correlative signals are separately band limited to a passband having a bandwidth that is about 1/8th of the bit rate of the original bit stream, and these band limited signals are then separately analog modulated, respectively, using in-phase and quadrature-phase components derived from a line carrier os-cillator.  The modulation products are then combined in a summing circuit to derive a single-sideband 7-level correlative signal.

Abstract: ABSTRACT OF THE DISCLOSURE        A device is provided including a pair of base sections adapted to be joined together along a generally vertical plane in approximate alignment with a pipe or other object extending through a roof or supported therein, such sections including a pair of molded plastic-supporting parts and a pair of skirt parts of elastomeric material which have overlapping edge portions and which define a downwardly facing surface secured by an adhesive to the upper surface of roofing material to provide a permanent weathertight seal.  A split boot is secured to the upper end of a tubular portion of the base sections and is of a stepped, severable construction for accommodating pipes or other objects of various larger sizes.  Lips at the split of the boot are secured together by a channel-shaped metal clip.          For smaller objects, a split plug is secured on the upper end of the split boot and has inwardly facing annular serrations for sealing engagement with an object.  A multi-purpose adaptor plug is also provided for use with a variety of shapes, sizes and orientations of objects.

Abstract: ABSTRACT        An operating lever mechanism for a hydraulic brake cylinder includes a pedal and a link operable connected at one end to a hydraulic piston and the cylinder and at the other end to the pedal.  Movement of the pedal is transferred to the link by means of a complementary abutment surface on pedal and abutment surface on link.  A shaft extends from the end of the link through an aperture in the pedal by an amount "a" when surfaces and abut; the distance "a" being equal to or greater than the distance "b" through which the pedal about aperture travels when the pedal moves between its rest and engaged positions.  The shaft and aperture retain the abutment surfaces in alignment even when the abutment sur-faces are separated by distances equal to or greater than the travel of the lever at the point of the abutment surface aperture.

Abstract: Abstract A rotary shouldered pin and box connection in an earth boring drill string is modified by eliminating some threads of the box to form a cylindrical portion and similarly cutting away some threads on the outer end of a pin to form a cylindrical portion. A sleeve is positioned in the box cylindrical portion to receive the pin end, with the result that bending forces are transmitted through the sleeve rather than through the threaded connection.

Abstract: ABSTRACT         A d. c. to d. c. converter which produces from a low voltage battery supply a high voltage d. c. output.  The converter comprises a step up transformer the primary of which receives current pulses under the control of an oscillator.  For each current pulse, the current builds up steadily and is then abruptly cut off so as to induce a high voltage pulse in a secondary of the transformer.  The high voltage pulses pass along a voltage multiplier to provide the high voltage d. c. output.  Each high voltage pulse has associated with it a low voltage pulse in the primary which is used to control the rate of the oscillator.  The oscillator is also controlled as a function of the peak current in the primary by a transistor, and the oscillator is further controlled to limit its maximum rate when the output current exceeds a given level, by means of a feedback loop.

Abstract: ABSTRACT OF THE DISCLOSURE    A harmony generator for an electronic organ, wherein the identity of played keys of the keyboard(s) is read into a storage device and then operated upon by a data processing device such as a microcomputer, so as to supplement the played note data with additional data designating "fill-in" notes which are to be sounded in addition to those actually played.  The data contained in the storage device, as supplemented, is then used to control the transmission of tone generator signals to the audio output system of the organ.  In a preferred embodiment of the invention, the criteria used to select fill-in notes cause notes correspond-ing to the nomenclatures of played notes of the accompaniment keyboard to be sounded as though played in the octave below the lowest note played on the solo keyboard.  Other fill-in criteria are also contemplated.  The fill-in notes are generated by combining played accompaniment data with masks.  The identity of these masks is based upon the nomenclature of the lowest or highest played note of the solo keyboard.  These masks can either be looked up in a table or generated by a suitable algorithm.  Fill-in notes can be generated simultaneously by more than one set of criteria, and the fill-in notes so produced can be separately voiced.

Abstract: Abstract of the Disclosure An automatic equalizer comprises a transversal filter connected to receive an input signal such as a television signal in which a predetermined periodic reference signal is present and having variable tap gains, and a correlator for forming the correlation bet-ween the input and output signals of the transversal filter and correcting the tap gains of the transversal filter to cancel out distortion components such as ghost component contained in the input signal.  For the pur-pose of preventing the slow convergence and fluctuation of tap gains of the transversal filter due to non-periodic noise components contained in the input signal, a circuit is further provided to integrate a predeter-mined portion of the waveform of the reference signal contained in the input signal.  An output signal of the waveform integrator circuit is correlated with the out-put signal of the transversal filter by the correlator.
