Abstract: ABSTRACT OF THE DISCLOSURE           An improved method and apparatus for fabricating insulated cables, particularly polymeric insulated electrical power cables, resistant to the formation and growth of electrochemical trees is disclosed.  Internal pressure on the conductor side of the cable when it is maintained lower than the external pressure on the outer surface of the insulation during extrusion.  Extrusion pressure higher than the external pressure results in expansion of the insulation following extrusion.  This expansion or swelling reduces the number and size of cracks and voids which are precursors of electrochemical trees.  In addition, pressure curing the extruded, insulated cable with a curing medium above its melting point followed by gradual gradient cooling under internal pressure and higher external cooling fluid pressure to around room temperature optimizes the resistance of the cable to nucleation and growth of electrochemical trees.

Abstract: ABSTRACT            A supply source of continuous elastic web and a support for the fixing of elastic elements are provided.  On the support there are located at least one clamping element fixed to the support itself and a further clamping element which is movable relative to the fixed element between first and second positions.  The distance between the fixed element and the movable element in the second position is less than the distance between the two elements in the first position and is substantially equal to the length of the tensioned elastic elements which it is desired to form.  The free end of the continuous elastic web is clamped in the movable clamping element when this element is in its first position.  Because of relative movement between the supply source and the support and the translational movement of the movable clamping element, when the movable clamping element reaches the second position, the web is clamped by the fixed clamping element whereby a piece of web extends between the fixed clamping element and the movable clamping element in a state of longitudinal tension the degree of which is determined by the velocity difference and the supply velocity of the web.  Finally, the web is cut in the region between the fixed clamping element and the supply source, so as to separate the said piece from the body of the web and define one of the tensioned elastic elements, and to form a new free end of the web itself.

Abstract: A Text to Speech System Abstract of the Disclosure The present system employs a microprocessor to accept ASCII signals representing text and transforms the same into coded signals representing phonemes, according to Hunnicutt rules for such transformation.  The microprocessor is programmed to generate a plurality of parameters (16 bit values every 6.4 milliseconds in a preferred embodiment) in accordance with the phoneme sequence for the text.  The parameters, which include mathematical considerations of the phoneme properties, are transmitted to a high speed digital signal processor whereat they are used to control multiplications and additions in doing programmed simulations of certain equations, thereby providing a digitized glottal waveform.  The digitized glottal waveform at this step of the operation includes sufficient information to provide 40,000 samples per second, in a preferred embodiment.  Thereafter the high speed digital signal processor subjects said digitized glottal waveform to a programmed low pass filtering operation to remove components of signals having frequencies in excess of five kilohertz and to provide some averaging of temporally adjacent values.  Next the present system subjects the low pass filtered, digitized glottal waveform to down sampling, in a preferred embodiment, at the rate of 10,000 samples per second.  The down sampled digitized waveform is then combined, under the guidance of a program, with a digitized waveform of aspiration sounds and then filtered by a set of digital resonators and this filtered combination is further combined with a waveform representing frication sound.  This last described digital waveform is transmitted to a digital to analog converter to provide an analog waveform (spoken version) of the text.

Abstract: Abstract of the Disclosure:       In an encoder operable in response to a discrete pattern signal divisible into a sequence of segments to produce an output code sequence, each segment is produced during a frame and specified by representative excitation signals extracted from each segment.  The representative excitation signals may be representative pulses placed in a selected one of subframes formed by dividing the frame with reference to a spectral parameter and a pitch parameter extracted from each segment.  Alternatively, the representative excitation signals may be either a combination of the representative pulses and a noise or a noise alone.  The representative pulses and the spectral parameters may be subjected to interpolation.  In a decoder for decoding the output code sequence into a reproduction of the discrete pattern signal, the representative pulses are interpolated to arrange excitation pulses in all of subframes of each frame and to produce an excitation vocal source signal.  The excitation vocal source signal may also be produced by the use of a decoded noise.  A synthesizing filter circuit is driven by the excitation vocal source signal to produce the reproduction.

Abstract: ABSTRACT            Circularly Polarizing Antenna Feed.           A circularly polarizing antenna feed comprises a feed waveguide having a short circuit reflecting plate at one end and a radiating horn at the other, a wave exalter for launching linearly polarized plane waves axially along the feed waveguide in opposite directions, and a grid of parallel reflector strips disposed in a plane which is perpendicular to the waveguide axis and which is located between the wave exciter and the reflecting   termination   at   a   distance   of approximately .lambda.g/8  from  the  exciter  and approximately .lambda.g/4  from  the  termination.     The reflecting strips of the grid are inclined at an angle of 45° to the direction of polarization of the waves propagated by the exciter, the grid and the reflecting termination together forming a twist  reflector which effectively reflects and rotates through 90° the waves incident  upon  the  grid.      These  reflected  waves together with the forwardly propagated waves from the exciter represent circularly polarized waves.   As an alternative to the reflector grid the feed may comprise a metal septum plate which has an axial length of .lambda.g/4 and which is disposed in the waveguide in an axial plane inclined at 45° to the polarization direction of waves propagated by the exciter and so that its front edge is located .lambda.g/8 behind the exciter.

Abstract: ABSTRACT OF THE DISCLOSURE           A day\night rearview mirror comprises an optical medium which is electrically driven between transmissive and opaque states. The mirror comprises a housing containing a circuit board assembly over which a mirrored reflecting sur-face is disposed. The mirrored reflecting surface is in turn overlaid by an optical transmission plate containing the optical medium. The transmission plate, mirror and circuit board are retained on the housing by means of a bezel. Electrical con-ductivity from the circuit board to the transmission plate is provided by helical coiled spring conductors which are con-veniently supported in sleeves integrally formed with a retain-ing frame for the mirrored reflecting surface of the mirror. The circuit board contains a circuit for controlling the optical transmission plate and suitable controls which are accessible to the user to adjust certain operational characteristics of the mirror assembly. It also includes a pair of photodetectors forming sensors which sense general ambient lighting conditions and incident light from the field of view, respectively. The sensors are coupled in electronic input circuits to a logic gate. The output of the logic gate controls the optical trans-mission plate. The transmission plate is forced to an opaque condition only when both a nighttime ambient condition is sensed and there are also bright lights from the field of view incident upon the the mirrored reflecting surface. The circuits impose cer-tain timing requirements on changes in sensed conditions so that the mirror does not change state in response to momentary departures from generally prevailing conditions.
