Abstract: ABSTRACT         A graphic record such as a bank signature card with a signature portion of limited area is registered by a framing clip on a carriage moveable under a photo-electric facsimile line scanner,  The carriage is manually moved to an inner, start-of-scan position where it is arrested by a stop and a motor drives it back  o its initial outer position past the scanner.          The stop is spaced with respect to the carriage the same dimension as the selected signature portion of the card so that only the signature is  canned in a minimum of time.  The stop is adjustable out of the carriage path so that the card or other graphic record can be scanned beyond the selected signature portion.

Abstract: REGENERATIVE BRAKE CONTROL SYSTEM                       FOR DC MOTOR            Abstract of the Disclosure A regenerative brake control system for a DC motor provides a resistor in series with the motor, a switch for short-circuiting the resistor and a chopper connected in parallel with a series circuit including the motor and the resistor for controlling the armature current of the motor by on-off opera-tion of the chopper.  There is provision for controlling the duty cycle of the chopper, and a filter circuit is connected through a diode to a parallel circuit including the chopper and the series circuit.  The duty cycle control includes an automatic current regulator for causing the motor current to follow the current command value.  An automatic voltage regu-lator controls the voltage not to exceed the equivalent source voltage, such voltage being equal to the motor voltage less the voltage drop across the resistor.  A switch control con-sists of first and second comparators for controlling a switch used for short-circuiting the resistor by utilizing the output signal produced from the automatic voltage regulator, which regulator acts on the current regulator to reduce the current command value.  The short-circuiting switch fails to operate in the voltage control region of the voltage regulator.

Abstract: PHASE LOCKED OSCILLATOR                          ABSTRACT     A phase locked oscillator comprising a phase comparator, filter and voltage controlled oscillator coupled in con-ventional manner to form the forward path of the phase locked loop and a counter and logic circuit coupled to form the feed-back path.  An input pulse stream is applied to a monostable flip flop which responds to each input pulse to produce a pulse of predetermined length that is applied to one input of the phase comparator.  The counter is coupled to receive the oscillator output pulses for counting repetitively to a predetermined count.          The logic circuit responds to first and second counts in the predetermined count for respectively generating and terminating a reference pulse in response to each input pulse.  The reference pulse is applied to the other input of the phase comparator which in turn provides an output signal indicative of the time dis-placement between each input pulse and its associated reference pulse to control the oscillator to run at a harmonic frequency of the input pulse stream.

Abstract: ABSTRACT OF THE DISCLOSURE:           A roll, of the type used in papar machines, is manufactured by rotating an inner roll body around its axis while simultaneously winding onto the outer surface of the inner roll body an elongated metal strip the convolutions of which press against each other so as to cover the outer surface of the inner roll body at the area of this outer surface onto which the strip is wound.  This strip has an inner edge surface engaging the outer surface of the inner roll body, an outer edge surface distant therefrom, and opposed side surfaces extending between the inner and outer edge surfaces.  At each of the wound convolutions of the strip the opposed side surfaces thereof respectively engage, over their entire areas, the adjoining side surfaces of adjoining strip convolutions over the entire areas of these adjoining side surfaces.  At any instant during the winding of the strip onto the inner drum body, the strip has an end convolution an inner side surface of which presses against the immediately preceding convolution and an outer side surface of which is exposed at one end of the series of convolutions which have already been wound.  A compressive force, which is directed parallel to the axis of the inner roll body, is applied against the outer side surface of this end convolution, during winding of the strip onto the inner roll body, at a location extending inwardly from the outer edge surface of this end convolution along the outer side surface thereof toward but terminating short of the inner roll body.  The magnitude of this compressive force is sufficiently great to deform and elongate the end convolution at the location thereof to which the compressive force is applied.

Abstract: SUBSEA MACHINE TOOL            ABSTRACT OF THE DISCLOSURE   A subsea machine tool for preparing the end of a bare piece of pipe in a subsea location for receiving an overfitting coupling.  The embodiment of the invention described in the application includes a support assembly adapted for raising and lowering in a body of water.  A pipe clamp is attached to each end of the support assembly for clamping the pipe at two axially spaced apart positions.  A split frame is supported by the support assembly for axial travel thereon, which frame is adapted for opening and closing about the section of the pipe intermediate the clamps.  A split ring gear assembly is supported by the frame for rotation therein and about the pipe section,  The split ring gear is in the form of a spool assem-bly wherein an involute gear forms one flange of the spool and a face plate forms the other flange.  The spool is supported about the exterior thereof by a split fixed ring which in turn is supported by the frame.  The fixed ring has mounted thereon one or more hydraulic motors which are arranged for rotating the ring gear relative to the fixed ring.  The face plate has mounted thereon for rotation therewith work means in the form of a milling machine which is radially movable and which serves the purpose of milling off any protrusions on the external sur-face of the pipe, as for example, a longitudinal weld seam.    Another tool is mounted on the face plate for sensing out-of-roundness of the pipe and the concentricity of the pipe rela-tive to the ring gear, and for providing a read-out of any variations in roundness or concentricity, which read-out may then be used to operate the milling machine to remove the dis-continuity.  In addition, the face plate has mounted thereon a rotary cutting tool for making a circumferential cut about the pipe, to thereby sever the same.  The tool is adapted for remote operation  such that deep water operations can be accom-plished.

Abstract: Abstract of the Disclosure An acoustical transformer or "phasing plug" for coupling sound from a speaker diaphragm to the throat of a horn. The phasing plug of the invention is in the general shape of a dome on one side and a truncated cone on the other, and has evenly spaced radial slots or channels formed therein, these slots forming air passageways for propagation of the soundwaves. The walls of the slots are tapered exponentially from their inlet ends at the speaker diaphragm towards a flat plane outlet at the throat of the horn, to provide an optimum impedance match between the output of the diaphragm and the input of the horn; the sound channels formed by the slots exponentially increasing in area between their inlets and outlets. Transformation from a spherical wave front at the input to a plane wave front at the outlet is assured by the shaping of the channels to make the distances between corresponding points at the channel inlets and outlets equal to each other.
