Abstract: ABSTRACT OF THE DISCLOSURE This invention provides an improvement in a spinneret assembly. The assembly comprises superposed rigid, first, second, third and fourth plate members. The first and second plate members partition off a first and second polymer chamber, respectively, from a second and third polymer chamber, respec-tively. The third plate member partitions off the third polymer chamber from one or more funnel-shaped fourth polymer chambers bored in the fourth plate member. The third plate member has a plurality of holes which are exposed to each fourth polymer chamber. The fourth plate member has at the lowermost ends of each fourth polymer chamber an orifice. The third plate member further has bored therein one or more slits, each slit being, on the under surface of the third plate member, of a multi-arm shape having at least three radially extending arms, each of which intervenes between at least two holes of the holes bored in the third plate member. The four plate members form a plurality of series of linked polymer passages, each series having at least one joining point at which two polymer streams join together. At least one of the polymer passages upstream of the joining point has at least one cross section that is narrower than any cross section of the polymer passage downstream of the joining point but up-stream of the succeeding joining point, if any, or said at least one polymer passage upstream of the joining point having a length longer than that of the polymer passage downstream of the joining point but upstream of the succeeding joining point, if any. The assembly produces multi-ingredient multi-core composite filaments each comprised of at least three polymer phases, and avoids defects in conventional assemblies which produce filaments which are not uniform in thickness and cross section and wherein the number of core polymer ingredients in each filament is limited, etc.

Abstract: ABSTRACT:              In an X-ray examination device which comprises an X-ray source for irradiating a body and which also comprises a detector device, a displaceable diaphragm device defines an angle of aperture which is substantially smaller, due to the selection of the dimension of the apertures, than the measuring angle defined by the associated radiation detector and the X-ray source.  By displacement of the aperture with respect to the object to be measured during the measurement over a distance which covers the measuring angle, a high-resolution shadow image can be formed.  The entire object is then contiguously irradiated.

Abstract: A B S T R A C T     Apparatus for Measuring Profile Thickness of Strip Material.     This invention provides apparatus for measuring the thickness profile of steel strip comprising a radiation source reciprocally movable in a stepwise fashion across the strip width on one side thereof and a single elongated detector on the other side of the strip aligned with the scanning source.  This detector may be a fluorescent scintillator which is responsive to the incident radiation, the amount of which is in turn dependent on the degree of absorption by the strip.  Means are provided for sensing the degree of excitation in the detector in synchronism with the scanning source whereby to provide an output respresentative of the thickness profile of the strip.     The profile may conveniently be displayed in analogue fashion on a television screen.     A conventional thickness gauge, e.g. of the X-ray type, may conveniently be used in conjunction with the profile gauge to compensate the output of the latter for any variations in the strip thickness along the length of the coil.

Abstract: ABSTRACT There is described a method of transmitting a digital signal in a burst mode using multi-level codes prepared by converting the digital signal into absolute values of a plurality of multi-level symbols and transmitted selectively as a symbol of a first polarity, a symbol of a second polarity opposite to the first polarity, and a zero level symbol.  Considering the transmission end, when the first bit of a digital signal processed into a block for transmission in correspondence with a burst is logical "1", the first symbol of the transmit burst signal is converted into a multi-level code provided with the first polarity.  On the other hand, when the first bit of the digital signal is logical "0", the logical "0" of the first bit is inverted into logical "1" and the first symbol of the burst signal is converted into a multi-level code provided with the second polarity.  The second and subsequent symbols are converted into a multi-level code provided with a polarity which is opposite to that of the average DC level before each symbol or, if the average DC level is zero, is opposite to that of the immediately preceding symbol except a zero level symbol.  Considering the receiving end, a burst synchronization signal is extracted from the first symbol of the burst signal, the absolute value of each of the symbols is converted into a digital signal, and the first bit of the digital signal is decoded into logical "1" when the first symbol is of the first polarity, and into logical "0" when the first symbol is of the second polarity. Because the first symbol of a burst signal is always non-zero which allows a burst synchronization signal to be extracted without resorting to any additional bit or symbol for burst synchronization.  Since the polarity of each symbol is so determined as to reduce the DC unbalance of a burst signal, the unbalance can be limited to within a maximum absolute value of one symbol regardless of the bit pattern of a transmit digital signal or the number of multi-level symbols. Deterioration in S/N ratio attributable to D.C. unbalance is negligible.

Abstract: ABSTRACT    Subscription apparatus and methods wherein an encoder begins inversion of a video signal during the last horizontal trace line of a randomly selected vertical interval and continues to invert trace lines in the following field of the video signal.  The encoder also suppresses the amplitude of randomly selected horizontal blanking pulses only during fields of the video signal while maintaining unaltered the absolute amplitude differential between the horizontal blanking pulses and associated horizontal synchronization pulses.  A decoder reinverts trace lines of the field following detection of an inverted last horizontal trace line of a vertical interval.  The decoder also selectively rebiases the video signal to restore the horizontal blanking pulses upon detection of a suppressed amplitude during the front porch of a horizontal blanking pulse.  Reinversion of the trace lines and rebiasing of the blanking pulses is achieved by selective reference biasing of a video modulator circuit in the decoder.

The monomeric mixture in the presence of the initiator is passed first into a stirred autoclave, in which it is partially polymerized.  Thereafter the reaction mixture from said autoclave, is passed through a heat exchanger, cooled to a predetermined value, and then subsequently passed to a non-cooled tubular reactor, in which the further polymerization is carried out under adiabatic conditions.

Abstract: ABSTRACT          A heated element mass air flow meter 10 includes a cylinder 20 having a surface 21 with an area of stagnation 22.  Element 11 is positioned aft of area of stagnation 22 and  forward  of  a  downstream  area  of  turbulence  23.          Deposition of air born dirt takes places at the stagnation area  because  dirt  particles  have  a  greater density and inertia  than  air  and  cannot  turn  as  easily.   The  air passing the element has been substantially separted  from air born dirt and carries less dirt than the remainder of the air stream.  The accuracy of heated element meters is reduced  by  deposition  of  dirt  on  the  element.    A configuration  as  described  reduces  the  amount  of  dirt striking the heated element 11 and improves accuracy of the meter.
