Title: Synchronized compressor and expander voice processing  system for radio telephone
Inventor: CHOW SHERMAN M
IPC: H03G7/00
Filed: 1977-09-19
Granted: 1980-11-18
Abstract: ABSTRACT OF THE DISCLOSURE         The voice processing system for radio telephone consists of a compressor in the transmitter and an expander in the receiver.  The compressor divides the input voice signal into syllabic groups and applies a gain to each syllabic group depending on the peak amplitude of the signal of the respective group, resulting in a reduction or compression of the dynamic range of the voice.  The expander on the other hand increases or expands the dynamic range of the signal restoring the voice to its original form.          The compressor and expander are synchronized such that the amount of expansion or instantaneous gain in the receiver is exactly the reciprocal of the amount of compression in the transmitter, i.e. when the gain of the compressor is N, the gain of the expander is 1/N. In this way the total system gain is always unity and is therefore transparent to voice and other analog signals passing through it.  A portion of the voice frequency band is pre-empted to carry a digital signal to synchronize the compressor to the expander.          This band designated as the control channel is located between 2500 to 2700 Hz and is used to carry binary frequency shift keyed (FSK) data stream which defines the instantaneous gain of the expander denoted by N.  The band between 300-2500 Hz is used to carry the compressed voice.  The effect of noise encountered in the transmission path is reduced because the soft syllables are amplified to the same amplitude as the loud syllable thus achieving an improved signal-to-noise ratio.

Abstract: ABSTRACT OF INVENTION          A slide valve for use in throttling solids flow, preferably including a pair of opposed discs in bearing contact with the valve seat.  The internal valve construction is unitized which simplifies removal as a single assembly, and permits quick reassembly as well as adjustment.  The discs are retained by guide bars to insure a back and forth motion.  The valve discs can provide central discharge to reduce flow impingement on the conduit wall which avoids or minimizes erosion, or they can be operated singly and/or independently or in conjunction with each other to provide flow control.  The load bearing and guide surfaces are protected from erosion by appropriately located hard-surfacing the integrally reinforced refractory.

Abstract: ABSTRACT OF THE DISCLOSURE            A cut-off die set is disclosed for use in a cut-off apparatus of the type in which continuous length of tubing or other elongated stock emanating from a tubing mill is severed into lengths as the tubing emanates from the tubing mill by means of a cut-off die set mounted within the cut-off apparatus.          The cut-off die set adapted to be clamped to the tube so as to move therewith during severing of the tubing by a ram operated cut-off blade descending vertically to shear the tubing.  The present disclosure involves an improvement to a notching mechanism often included in such cut-off apparatus in which a horizontally reciprocated blade notches the upper portion of the tubing just prior to severing by the main cut-off blade so as to eliminate dimples in the severed tube cross section.  The improvement lies in a different timing of the movement of the notching blade with respect to the motion of the main blade.          The notching blade is pulled from an initial position over the tube across the upper portion of the tubing, to notch the same, prior to the operation of the main cut-off blade which is followed by the return stroke of the notching blade through the opening in the tube created by the main cut-off blade.  This drastically reduces the velocity of the notching blade operating mechanism, improving wear on the blade and other movement parts as well as reducing the loads on the operating mechanism.  In addition it eliminates the blade drag normally associated with withdrawal of the notching blade prior to severing of the tubing section as occurs in conventional designs.

Abstract: ABSTRACT OF THE DISCLOSURE         Rotary earth boring bits according to the present invention and method of assembly thereof allow development of a rotary earth boring bit construction of low cost nature and having exceptionally good wear life.  The drill construction promotes the use of optimum bearing materials for rotary support of the cutters of the drill thereby promoting exceptionally good service life.  Additionally, the bearing of each cutter assembly may be lubricated so as to further enhance the service life of the drill.  Assembly may be accomplished at low cost by taking advantage of dimensional changes of the parts respon-sive to heating or cooling.  The drill cutter may be heated to increase the dimension of the bearing cavity formed therein while the bearing and its support spindle may be cooled to reduce the external dimension of the bearing.  Following assem-bly of the bearing and spindle to the cutter a tight retention fit will develop between the bearing and cutter as these parts approach normal temperature.  To further insure retention of the cutter in assembly with the bearing, a retainer element may be located during assembly within register    retainer grooves formed in the cutter and bearing.

Abstract: GLASSWARE FORMING MACHINE OF THE I.S.             TYPE WITH IN-LINE MOLD MOTION                ABSTRACT OF DISCLOSURE         An individual section of a Hartford I.S. type glass-ware forming machine is modified to provide for in-line, or parallel motion, of the split mold halves at both the blank and blow stations.  Vertically extending rock shafts move the blank and blow mold holder structures on fixed ways, through toggle links similar to those in a conventional I.S. machine, but the space formerly occupied by the hinge pin at the blow side is made available for the mold structure because the ways are oriented parallel to and slightly below the neck ring hub mechanism.  This design provides for an increased mold closing force at the blank side and simplifies the mold holder structure itself whereby the molds can be continually cooled from an internal chamber in the mold holder which is supplied with cooling air through a vertical interface between the movable mold holder structure and the fixed machine frame.

Abstract: ABSTRACT           A torsional vibration damper of the type having an inertia ring coupled to a hub by an elastomer member. The inertia ring is formed of two axially spaced ring parts.  Each ring part carries an annular groove.  A radially extending disc locking element (in the form of a flat washer) carries an axially extending key, the ends of the key being deformed towards a radially extending position by pushing the two ring parts together, the deformed key ends thus holding the two ring parts in assembly.  The disc locking element also is compressed and thus exerts an axial force urging the two ring parts apart.  In an embodiment, the disc locking element carries a second axially extending key, radially spaced from the first key and is similarly deformed into a second annular groove.  In still another embodiment, one inertia ring part carries an integral, axially extending locking key. This key is received by a complementary annular groove in the other ring part, the disc locking element being optionally omitted.  A similar deformation and locking action occurs upon pushing the two ring parts together, to thereby assemble the damper.

Abstract: 47,556 ABSTRACT OF THE DISCLOSURE         The preferred embodiment of the invention com-prises a glass sealed thyristor and a method for simul-taneously  constructing  a plurality of thyristors and a common semiconductor wafer.  The thyristor utilizes a body of  semiconductor  material  with  the  cathode  and  base regions  extending  to  one  major  surface  and  the  anode region extending to the second major surface.  A groove is etched in the first surface of the body of semiconductor material to expose the PN junction formed at the interface of the cathode emitter and cathode emitter base regions.     A second groove is etched in the second major surface to expose  the  PN  junction formed at the interface of the anode emitter region and the anode emitter base region.          Ring shaped glass members are fused to the body of semi-conductor material to form seals providing environmental protection  for the PN junctions exposed by etching the grooves in the major surfaces of the body of semiconductor material.  A plurality of thyristors can be simultaneously constructed on a common semiconductor wafer.
