Abstract: Abstract:     A magnetic recording medium is formed on a rotary drum and is divided into a plurality of magnetic tracks.  On each tract there is recorded a magnetic signal of a combi-nation of a magnetization portion which consists of two consecutive unit magnets (pitch .lambda.) and a no magnetization portion having the same length (2.lambda.) arranged to alternate over the whole periphery of the track.  First magneto-resistive elements in the magnetic sensor are arranged in pairs opposite the magnetic tracks at a distance of .lambda./2. Second magnetoresistive elements opposite the magnetic track that corresponds to the lowest-order bit of the position detecting signals have a number of 2m relative to the first magnetoresistive elements at a distance of ( )SML, where SML denotes the length of the magnetic signal of the magnetic track, m denotes the number of increased bits, and n denotes an integer.  Detecting signals are thus obtained in a bit number in excess of the number of magnetic tracks and the detector can be made small and light.

Abstract: ABSTRACT OF THE DISCLOSURE   A cationic ring-opening polymerization of a cyclic ether ("CE") in conjunction with an unsaturated alcohol (propagator) having an allyl double bond, produces a polyether macromer having an allylic group near one end and a hydroxyl group at the other; and prior problems associated with the use of olefinic monomers to produce such macromers are avoided; the macromers may be employed to produce a variety of graft and comb copoly-mers including liquid polymers which are beneficial as dispersants in polymerizations by lowering the viscosity of the reaction mass; in particular the macromers may be quaternized to yield anti-statics, fiber softeners, excipients for drugs and biomimetic drugs; the cationic ring-opening 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 glycidyl ether; the propagator is a primary or secondary alcohol which, if cyclic may have a single internal double bond in one ring; the catalyst is a Friedel-Crafts acid, strong protic organic or inorganic acid, oxonium salt, or the like; the macromer formed may be homopolymerized to yield a polyvinyl homomacro-mer with pendant chains of polymerized CE; or the CE may be copolymerized with a wide variety of olefini-cally unsaturated monomers to form a macromer copolymer; or, plural cyclic ethers may be (a) sequentially poly-merized 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.

Abstract: METHOD AND APPARATUS FOR PRECISION DYNAMIC    DIFFERENTIAL POSITIONING     ABSTRACT OF THE DISCLOSURE          A method and apparatus for rapidly and accurately determining the position coordinates of a remote, movable receiver relative to a fixed reference receiver.  The technique utilizes successive code measurements and carrier phase measurements of both the L1 and L2 carrier signals broadcast from four or more orbiting GPS satellites.  Code measurements based on a weighted average of the individual L1 and L2 code measurements in each satellite/receiver link are adjusted in accordance with the corresponding carrier phase measurement for an L1-L2 carrier difference signal and are further smoothed over time.  This yields a rapid determination of the remote receiver's position coordinates, with progressively increasing accuracy.  After merely about two to three minutes of processing, a standard carrier phase procedure can be implemented to yield a position determination that is accurate to within about one centimeter.

Filed: 1987-12-16
Abstract: In a television broadcast and reception system for the transmission of PAL signals accompanied by an additional stereo signal for enhanced audio reception the television received has equipment to indicate, whether or not the input signal is valid by utilizing two decoders which decode the presence of a FAW (Frame Alignment Word) together with a 1, and a FAW together with an O. The output from these detectors is applied to threshold circuits which decide the "good to bad" rate of "FAW and C" bit detections. A mark/space detector is formed of two counters, the final counter of which counts up if the input to mark space is above a critical value. For a correct FAW lock, both counters count up and the circuit gives a valid output for a correct input sequence. This equipment, together with a C0 detector and timer circuit forms a locking arrangement immune to substantially all false lock sequences which might occur.
