Abstract: STATISTICAL DATA DETECTION METHOD AND APPARATUS          Abstract A statistical data detection method for use in a synchronous data transmission system employing either phase modulation, combined amplitude and phase modula-tion or quadrature amplitude modulation.  The signal space diagram of the possible states of the transmitted signal and their influence zones is divided into N ele-mentary squares.  Since the squares are rather coarse to save storage space, many such squares belong to more than one influence zone.  The influence zone of a state Z defines the region within which the received signal, P, will lie when state Z has been transmitted.  A word in a ROM is assigned to each elementary square, and each word comprises two entries.  The entries are identical when a square falls wholly within a single influence zone.  Other-wise, the entries are different.  Parts of the received signal are converted into an address for addressing the ROM.  If the two entries of the word read from the ROM are identical, detection is completed, the transmitted state is the state represented by the entries.  If the two entries are different, however, signifying two dif-ferent states, the square of the distance between P and each of the two states is computed.  The closer state is indicated as the most probable transmitted state.

Abstract: Abstract of the Disclosure A thread-forming screw has a work-entering section for forming a thread in a workpiece and a work-holding section adjacent thereto.  Both sections are of an arcuate, polygonal lobular configuration in cross-section.  The amount of lobulation on the holding section is considerably less than the lobulation on the work-entering section, which is of such magnitude as to insure effective thread-forming at low torque.  The lobulation on the holding section is prefer-ably just sufficient to effect a locking action with the thread of the workpiece and also to improve the stripping torque of the screw from the workpiece.  The work-entering end of the fastener also has a pilot thread of about one turn and with a uniform width over 360° and sized approximately the same as the pilot hole in the workpiece to prevent cocking of the fastener as it is initially inserted into the pilot hole.  Thread-rolling dies for forming the fastener have a die section with grooves of equal depth to roll the pilot thread.

Abstract: ABSTRACT OF THE DISCLOSURE             The invention relates to a system for screening incoming signals to separate acceptable signals from unacceptable signals, and to apply the acceptable signals to a function generator.  The system includes a signal transmitter and a signal receiver.   The receiver includes a signaler and a functional generator in alternative normally-closed circuit with the trans-mitter, and a sensor for opening the circuit to the signaler and closing the circuit to the function generator upon passage to the sensor means of an initial signal from the transmitter. A detector and a decoder operate when the circuit between the signal transmitter and the function generator is closed, to separate selected transmitted signals from unselected transmitted signals by filtering out the unselected signals and serially converting the selected signals into data bits representing digits. The system also includes a memory which has both a main memory and an auxiliary memory.  A programer directly and selectively pro-grams the main memory with selected digits, and a comparator com-pares the output of the auxiliary  memory with the the output of the main memory to obtain an acceptable signal when the outputs match. The acceptable signal is transmitted to the function generator.

Abstract: ABSTRACT            The present invention relates to sizing compositions for coating glass fibers, as well as similarly-coated fiber, to protect them against abrasion during standard textile operations.  Glass fibers, as is known, are made by the attenuation of small molten threads flowing from the holes of a threading-die or bushing. These glass threads are thinned out to form continuous filaments in an attenuating process, by winding the filaments, after they have been collected into a thread, onto a spool turning at a very high speed.  before being collected into a thread, the filaments are coated with a using by passing through a continuously-fed sizing device.
