Abstract: Abstract of the Disclosure A breaker reinforcing tape for belted pneumatic tires, a method of making such tape, and a method of constructing such tires therewith, are disclosed.  The tape includes a generally sinusoidally crimped strip of uncured rubber and a plurality of similarly crimped parallel cords having their undulations following and nesting in the undulations of the crimped strip, the cords at successive apexes being secured to successive apexes of the strip.  A second uncured rubber strip in a flat condition is secured to alternate ones of the apexes of the undulations of the array of cords and the crimped strip at one face of the latter.  At least one frangible element is interposed in a fixed and substantially flat condition between the crimped and flat strips for releasably reinforcing and stabilizing the flat strip against inadvertent expansion that would prematurely reduce the amplitude and frequency of the undulations of the crimped strip and its associated cords.  The tape, when used in making a tire, is wound helically about the crown region of the carcass, out-wardly of the breaker piles, at an angle of substantially zero degrees to the mid circumferential plane of the carcass.  This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

Abstract: Abstract of the Disclosure A process and apparatus for producing spun yarn using an electrostatic field produced by a pair of spaced electrodes, one of which surrounds the other to isolate the electrostatic field therebetween from external physical and electrical disturbances.  Staple fibers are fed into the field through an aperture in the surrounding electrode for migration in the electrostatic field to a linear zone of increased field intensity from which the fibers are withdrawn and twisted to form a spun yarn, which may be done without the use of a core yarn or with a core yarn drawn through the linear zone and subjected to a false twisting operation to collect and twist the fibers thereon.  Beyond the linear zone is another zone of increased field intensity for electrosta-tie collection of fly and other waste material.  Suction is applied to remove the fly and other waste material from the electrostatic field and also serves to draw the feeding fibers through the aperture into the electrostatic field.

Abstract: METHOD AND APPARATUS FOR RECEIVING DISPARATE SEQUENCES OF SPACED TONE BURSTS             Abstract of the Disclosure This invention pertains to a method and arrangements that provide automatic detection of sequences of signals which previously required listening by operators in telephone systems to identify them.  In a telephone system, certain information is transmitted using preselected signal sequences of tone bursts and silent intervals.  These signal sequences are subjected to interference by speech and noise occurring in the telephone system.  An arrangement is disclosed which reliably recognizes and identifies these signal sequences notwithstanding the apparent modification thereof due to the interference.  In the process of recognizing these signal sequences, a three-stage recognition test is utilized to classify the durations of tone bursts and silent intervals in the signal sequences that occur.  The validity of the signal sequence is checked by detecting inconsistent durations within the sequences.  This feature is also utilized to indicate faulty apparatus used to generate these signal sequences.  A dual arrangement is also disclosed wherein signal levels of a particular signal sequence in different transmission paths in telephone systems indicate the origin of the sequence.  A level comparison which is successful for a preselected portion of the total duration of the signal sequence provides a margin of tolerance for interference in the sequence.
