Abstract: SPECIFICATION     "MULTIPLE SPINDLE MACHINE TOOL"                    ABSTRACT OF THE DISCLOSURE      A plurality of multiple spindle toolheads are stared in a carousel-type toolhead magazine on top of a machine tool which includes a toolhead driver for driving any selected one of the toolheads.   The toolhead driver is mounted for movement along a Z axis toward and away from a worktable.   A rotary toolhead changer arm for transferring toolheads from the toolhead maga-zine to the toolhead driver and vice versa is mounted on the machine for rotation about an axis which is inclined at an angle of 45° to the Z axis.  The toolhead changer arm has two diamet-rically opposed ends which are each inclined at an angle of 45° to the rotary axis of the toolhead changer arm.  Clamps are moun-ted on both ends of the toolhead changer for clamping toolheads thereto.  When the toolhead changer arm is rotated through 180°, one end moves a toolhead from a position adjacent to the tool-head driver to a position adjacent to the toolhead magazine while the other end moves a toolhead from a position adjacent to the toolhead magazine to a position adjacent to the toolhead driver.

Abstract: ABSTRACT OF THE DISCLOSURE:      A mechanical hand amusement device consisting of a movable grip member joined by a rod, which extends through a tubular arm, to a hand member having a fixed thumb and four finger members which bend inward when the grip member is squeezed.  Each finger member includes three hollow segments which are joined by flexible hinges at the tops, and have a flexible strap which is anchored within the fingertip seg-ment running along the bottoms.  The strap extending through each of the finger members is coupled to the rod so that a portion of the strap is retracted into the hand member when the grip member is squeezed.  The resulting forces move the finger members inward in a grasping motion.  A spring within the hand member returns the elements to their at-rest posi-tions when the grip member is released.

Abstract: ABSTRACT OF THE DISCLOSURE           Process for preparation of smoke retardant compo-sition containing an amine molybdate and cupric oxalate. According to the process of this invention, the individual components of the composition are synthesized in a common reaction slurry, thereby, resulting in their intimate assoc-iation with one another.  This process generally involves reacting in this common reaction slurry an appropriate amine with a molybdenum compound, such as molybdenum trioxide, molybdic acid, an ammonium or alkali metal salt of molybdic acid or mixtures thereof.  Oxalic acid and cupric sulfate can thereafter be introduced into this reaction medium.  The amine and the molybdenum containing compounds will react with one another thereby forming an amine molybdate complex. The oxalic acid and cupric sulfate will react with one another thereby forming cupric oxalate and sulfuric acid. The generation of sulfuric acid during this latter reaction serves to stabilize the amine molybdate thus rendering it more readily acceptiblize for use in the smoke retardant compositions of this invention.  The process parameters and relative proportion of ingredients of the above synthesis are carefully adjusted so that they yield a coherent particulate material comprising cupric oxalate and amine molybdate in intimate association.  Compositions prepared in the above manner are highly effective smoke retardants for vinyl halide polymers.

Abstract: Abstract of the Disclosure An automatic adaptive equalizer operative on a test pattern including a carrier-only period, clock-only period and a single test impulse.  The equalizer employs a transversal filter under control of a microprocessor.  Samples of in-phase and quadrature phase components of the received impulse response are cross correlated and autocorrelated to form elements of a complex matrix equation describing the optimum equalizer tap settings.  The microprocessor performs a special iterative operation utilizing elements of this equation to rapidly and exactly calculate the optimum initial settings for the tap constants.  The clock-only portion of the test pattern is analyzed to accurately set a sampling clock to properly sample the received impulse so that the matrix formation can be carried out during the duration of the received impulse.  Initial equalization can be achieved in a time on the order of 30 milliseconds at a data rate of 9600 bits per second.

Abstract: SPEECH DETECTOR WITH VARIABLE THRESHOLD                       Abstract A speech activity detection circuit and method are described in which a digitized sample of the analog speech signal in a communications system is taken n times in a period of time t.  The magni-tude M of each sample is calculated and the largest value of M which is encountered over a given period t is stored as a peak magnitude ?(t).  This value is compared to a value ?(t-1) which is the smallest value of ?(t) from prior periods.  The lesser of the two values is stored as the new value for ?(t-1).  The process is continued for i periods and at the end of the ith period, the value ?(t-1) is multiplied by a constant k and the product is stored as the threshold value for the next i periods of time t. Thus, the largest signal sample magnitude over a period of time t becomes, upon multiplication by constant k, the candidate "standard" threshold level for determining whether speech exists.  If this candidate is smaller than the previously stored value for a previous period of time, then the candidate becomes the new standard.  In this manner, the threshold level effectively floats or varies with the conditions of the incoming signal.
