Abstract: Abstract A Skew Detection System for Optically Read Data A skew correction system for data media, especially optical data storage media wherein a pair of identical geometric marks are spaced apart in a band or track parallel to a data track, the data tracks being transverse to the direction of relative motion of the data storage medium with respect to a detector. As the medium moves relative to the detector, a linearly scanning detector, portions of each geometric mark are observed by the detector. A ratio of picture elements is determined using the two sets of observed picture elements. If the ratio is other than 1, skew exists. A closed-loop servo system is used to restore the ratio to 1, thereby eliminating skew. The geometric marks may be disposed forward of the data tracks, astride the data tracks, behind the data tracks, interspersed with the data tracks, or if different colors of light are used, atop the data tracks.

Abstract: OPTICAL FILTER POLARIZER COMBINATION AND LASER APPARATUS INCORPORATING THIS COMBINATION                 Abstract of the Disclosure The present invention deals with an optical filter polarizer combination providing a spacial transmission function to polarized incident light.  When the light is in the form of a beam the combination may be used to reject extraneous light, or to modify the intensity profile of the beam as a radial or as a linear spacial function (orthogonal to the axis of the beam).      The filter employs two lens elements of birefringent materials, with their crystal optical axes mutually orthogonal, and at 45° to the plane of polarization.          Spherical lenses are employed for a radial spacial function and cylindrical lenses are employed for a linear spacial function.      The combination is useful for mode selection in a stable laser oscillator, for beam quality improvement in a stable/unstable oscillator, and for fill factor enhance-ment in coupling energy from a laser oscillator to a laser amplifier.

Abstract: STYRYL TERMINATED MACROMOLECULAR MONOMERS OF POLYETHERS             ABSTRACT OF THE DISCLOSURE A cationic ring-opening polymerization of a cylic ether ("CE") in conjunction with an unsaturated alcohol (propagator) having a styryl or substituted styryl group, produces a polyether macromer having the styryl group near one end and a hydroxyl group at the other. The polymerization proceeds by polyaddition of the CE to the OH group which is the propagating species.  The CE is an alkylene oxide or an aliphatic or aromatic gly-cidyl ether; the propagator is a primary or secondary alcohol.  The catalyst is a Friedel-Crafts acid, strong protic organic or inorganic acid, oxonium salt, or the like.  Plural cyclic ethers may be (a) sequentially polymerized to form macromer block copolyethers, or, (b) polymerized randomly to form macromer copolyether co-polymers.  The cationically ring-opened macromer formed always contains a trace of a cyclic oligomer of the CE. The macromer formed may be homopolymerized to yield a homopolymer of the macromer with pendant chains of poly-merized CE; or the macromer may be copolymerized with a wide variety of olefinically unsaturated monomers to form a copolymer of macromer.

Abstract: ABSTRACT OF THE DISCLOSURE           To regulate a single sideband up converter having a pair of mixer stages (M1, M2), each mixer stage receives control signals to compensate for spurious signals of the mixer components.          Part of the radio frequency output signal (RF') from the con-verter is fed to a down converter (M3).  From the resulting down-converted signal, the original intermediate frequency signal (IF) as well as the first harmonic thereof are filtered out as a measure of oscillator and sideband suppression.  From these filtered-out signals, control signals for the mixer stages (M1, M2) are obtained.

IPC: C08G63/78
Filed: 1967-03-23
Abstract: Linear polyesters or copolyesters of high molecular weight are prepared by esterifying bifunctional organic acids with diol esters of these acids at high temperature and pressure greater than atmospheric, then carrying out a polycondensation reaction on the product at higher temperatures Previous preparations (e.g. U.S. Patent 3,070,575 and British Patent 775,030) used refluxing conditions at atmospheric pressures. In the equilibrium established there was a significant amount of free diol which had to be evaporated and condensed and this increased time of reaction and energy consumption. Further, undesired glycol ethers were formed and these lowered the melting point of the product.
