Abstract: ELECTRICALLY TUNABLE INDUCTOR AND METHOD                           ABSTRACT     A radio receiver having a tunable RF stage with an electrically tunable inductor is disclosed.  The tunable inductor consists of a magnetic device with a core whose degree of magnetic saturation is controlled by various control currents.  A phase lock loop with a programmable frequency divider responds to inputs from a tuning control means and provides a local oscillator signal to a mixer in the radio receiver while also providing a control current to the magnetic device, defined herein as Current Controlled Inductor (C.C.I.), which is directly related to the frequency of the local oscillator signal supplied to the mixer.  Each time the radio receiver is tuned to a different input frequency by changing the frequency of the local oscillator signal, a predetermined reference current is applied to the C.C.I. before a new control current corresponding to the new local oscillator frequency is applied.  This results in always tuning the C.C.I. in a single direction and therefore accurately setting the C.C.I. to desired values of inductance despite any hysteresis characteristic of the C.C.I.  During the time that the C.C.I. is being set by the reference current, a muting signal is created by a monostable multi-vibrator which silences the speaker of the receiver via an audio gate.  In this manner the receiver effectively ignores the time that the C.C.I. is being set by the reference current.

Abstract: Abstract A tire building apparatus is provided having an improved mechanism for turning up the plies of the tire carcass and wrapping them around each tire bead ring.  The mechanism is designed so that it can also be used to apply the sidewall pads to the expanded carcass of a radial tire.  The improved mechanism includes a bladder that has a molded conical portion in its outer wall portion adjacent the building drum.  This conical portion extends very close to the bead ring positioned adjacent the carcass at the sides of the drum shoulders.  The improved mechanism also includes a control ring insert placed inside said bladder and radially inwardly from the conical portion of the outer bladder wall portion. When the bladder is inflated to wrap the carcass plies around the bead ring, the control ring insert and the molded conical portion of the outer bladder wall portion combine to provide an improved, tighter wrapping of the carcass plies around the bead ring.  They also provide a smoother, more accurate positioning of a sidewall pad to an expanded radial tire carcass when the mechanism is employed for that purpose.

Abstract: RIGID INSULATION ASSEMBLY                   ABSTRACT OF THE DISCLOSURE     A rigid insulation assembly including a plurality of panels of rigid insulation fixed in edge-to-edge relationship on a base sheet to form a continuous length of insulation material wound on a core member whereby the insulation may be readily handled and be quickly applied to a roof deck by unrolling the material.  The core is of polygonal cross-section so as to define a plurality of faces about its periphery, and the panels in the innermost layer on the core are of substantially the same width as the faces with the panels in each successive layer outwardly from the innermost layer having progressively greater widths so that the joint lines between adjacent panels are located sub-stantially on radial lines passing through the corner edges between the faces of the core.  Accordingly, the panels in the first layer lie flatly against the core and the panels in each successive layer lie flatly against the panel in the layer inwardly therefrom so that there is no danger of the panels being torn away from the base sheet because of a rolling effect.  The panels have one edge with a convex cross-section whereas its other edge is con-cave in shape so as to receive the convex edge of the adjacent panel   and form       a V-joint Which provides better insulating characteristics, and the interlock between the panels provides a stronger structure.

Abstract: ABSTRACT OF THE DISCLOSURE         A process is disclosed for preparing fiber of desirable cross-sectional shape.  The process comprises preparing a homogeneous single phase fusion melt of a fiber-forming acrylonitrile polymer and water and extruding the fusion melt through a spinnerette directly into a steam-pressurized solidification zone maintained under conditions which prevent formation of a sheath-core structure in the resulting extrudate and enable orientation stretching to be effected.  The spinnerette is modified by securing a strand of wire therein to block part of its useful spinning area and to provide the structured cross-sectional fiber shape.  The nascent extrudate is stretched while it remains in the solidification zone to provide orientation of the polymer molecules.

Abstract: Abstract of the Disclosure Boron trichloride is prepared in substantially stoichiometric quantities by free-radical chlorination of borate ester, e.g., trimethyl borate, at temperatures of between about 20C. and 100C., more preferably between about 40C. and about 90C.  The mole ratio of chlorine to borate ester is from about 5.5:1 to about 7.5:1.  Reactor pressures are moderate, e.g., generally less than 3 atmospheres absolute.  Atmospheric pressure can be used.  An inert liquid organic solvent, e.g., carbon tetrachloride, can be used as the reaction medium.  Gaseous reaction products are removed from the reactor during the chlorination reaction.  In addition to boron trichloride, carbon monoxide (rather than phosgene) and hydrogen chloride are the principal products of the chlorination reaction.  Phosgene is produced in substantially lower amounts than when chlorination is conducted at autogeneous pressures and the chlorine:trimethyl borate mole ratio is 9:1 or more. The boron trichloride product is separated from the carbon monoxide, hydrogen chloride and phosgene products, and recovered.

Abstract: 1                 PHN. 9386.        ABSTRACT:      A method of demodulating a quadphase coded data signal and a receiver for carrying out the method.         A quadphase code comprises four elementary waveforms 1,1; 0,1; 0,0; and 1,0, each waveform repre-senting two bits of an original non-coded binary sig-nal.  Each elementary waveform consists of four half bit intervals, the signal corresponding to the first and the second bit, respectively, being transmitted in the first and the second half bit intervals and the signal corresponding to the inverted values of the first and the second bit, respectively, being trans-mitted in the third and the fourth half bit intervals.           In a receiver such a signal at an input terminal is sampled in each of the four half bit intervals by means of two sample-and-hold circuits and two sampling switches.  In principle, all informa-tion is already available after the sampling operations in the first and the second half bit intervals, by the circuits but by utilizing all four samples a proper protection from noise, interference and zero level shifts is obtained.  Comparators 6 and 7 determine, respectively, the difference of the samples taken is the first and the third half bit intervals and the difference of the samples taken in the second and the fourth bit intervals.  A positive difference represents a logic 1, a negative difference a logic 0.  A combin-ing circuit interleaves the two difference signals obtained, the signal from comparator being delayed half a bit interval by a delay circuit, to produce the decoded original signal at the output terminal 18.  A clock synchronization device controls the timing.           The method and the receiver have applica-tion in the field of data transmission over physical wire pairs and in the field of magnetic and optical recording.
