Abstract: Div.                  METHOD AND APPARATUS FOR WINDING AND TWISTING YARN                 ABSTRACT OF THE DISCLOSURE A method and apparatus for winding and twisting yarn onto a spool directly from an extrusion line or other production source by means of an inline twister. The inline twister comprises the following elements;  a rotatable spindle, a bottom flange securely fastened to the spindle having a catch on the outer periphery, a removable interlocking top flange positioned on the spindle, means for positioning the spool concentrically about the spindle, a twister ring concentrically po-sitioned about the spindle having a slit, and a rotatable traveler positioned on the twister ring having a hook inwardly directed toward the spindle.      The method of winding and twisting the yarn onto a spool comprises guiding the yarn adjacent to the spool. This yarn is then positioned adjacent to the slit in the twister ring and is allowed to pass therein.  The spindle on which the spool is contained is then rotated so that the catch-equipped bottom flange contacts the yarn and holds it tight.  As the yarn is rotated by the bottom flange it contacts the hook equipped rotatable traveler positioned on the twister ring and this combination of rotating flange and traveler provides the means for inserting twist into the yarn as well as wrapping the yarn about the spool.  As the yarn is wound about the spool the twister ring is reciprocated so that the point of collection varies about the spool.

Abstract: ABSTRACT OF THE DISCLOSURE         A horizontal bandsaw machine is provided in which the upper or returning limit of the bandsaw blade can be readily determined according to the height or size of the workpiece to be cut so as to minimize the idling of the bandsaw blade.  The bandsaw blade can also be automatically lowered at a fast rate from its upper or returning limit towards the workpiece to be cut without making any cutting action so as to further minimize the idling of the bandsaw blade.  The bandsaw blade is automatically stopped from rising at its desired upper limit and thereafter is lowered initially at a faster rate and then is slowed down when cutting into the workpiece thereby to provide an accurate cutting action.

Abstract: ABSTRACT OF THE  DISCLOSURE        A method of depositing a metal coating on the wall of a chill mould for use in continuous casting wherein the mould is placed in a deposition bath such that an internal wall thereof to be coated is oriented generally upright, the deposition bath being composed of a solution containing at least one nickel salt and a suspension of particles of a hard material having a critical deposi-tion temperature range defined by upper and lower limit temperatures.          A metallic layer containing nickel is deposited on the mould wall either by electrolytic or by electroless techniques, and during such deposition the mould wall is maintained at a temperature in the vicinity of one of the upper and lower limit temperatures while the solution is maintained at a temperature in the vicinity of the other of the limit temperatures, the temperature difference between the mould wall and the solution being within the aforesaid critical deposition temperature range.  During deposition, the solution is maintained in a turbulent state and is circulated at a speed in excess of the sedimentation speed of the hard material particles suspended therein and also in the opposite direction to rising and falling currents along the mould wall.  Where the mould wall is made of copper and the deposition is performed by an elec-troless method, the mould wall can be treated by applying to it a stream of free-falling iron balls which are recirculated.

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE DENSITY OF DISPENSED HOT MELT THERMOPLASTIC ADHESIVE FOAM Abstract:          A method and apparatus are disclosed for controlling the density of dispensed hot melt thermoplastic adhesive foam in order to assure uniform foam characteris-tics.  In order to create the hot melt adhesive foam, air or any relatively inert gas is mixed with the thermo-plastic adhesive while the adhesive is in the molten state, and the mixture is then pressurized so as to force the gas into solution with the molten adhesive.          As the molten adhesive/gas solution is dispensed at atmospheric pressure, the gas is released from solution and becomes entrapped in the adhesive so as to form a homogenous  closed cellular adhesive foam.  According to the practice of this invention, the supply of gas is periodically discontinued so as to prevent an excess volume of gas from being admixed with the molten adhesive whenever foamed adhesive is not being dispensed, thereby stabilizing the density of the adhesive foam.

Abstract: Abstract of the Disclosure A DC coupled system for automatically controlling the high frequency peaking content of a video signal is disclosed.  The system includes a DC coupled control path comprising a peak detector for developing a control voltage representative of the high frequency content of the video signal exclusive of video signal DC components.  The detector is preceded in the control path by a frequency selective network comprising an amplifier and a filter for shaping the frequency response of the control path such that high frequency video signal components exclusive of DC video signal components are passed to the peak detector.  The frequency selective network comprises the cascode combination of a video signal amplifier transistor and a current source transistor which provides quiescent operating currents for the amplifier transistor. The filter is coupled to the junction of the amplifier and current source transistors, and includes a DC blocking network coupled between the junction and a point of reference potential.

Abstract: Abstract Of The Disclosure An automatic fingerprint enrollment and identi-fication  technique is provided for automatically pro-cessing an input image represented by pixels having either a one or a zero value.  The automatic processing involves a series of steps in which the initial processing is a rough screening technique for eliminating a reasonable portion of the noise while passing through almost all of the minutia. As the steps proceed, the processing becomes more complex to provide a tighter screening out of noise while passing through as much of the minutia as possible.  The later steps by operating on relatively fewer minutia or anomaly points that the earlier steps can be economical though more complex so as to be more discriminate than the earlier steps.  The processing provides an optimum trade off between enrolling as large a proportion of the popu-lation as possible while minimizing the number of false identification errors.
