Abstract: 1305995 Phase detectors CKD PRAHA OBOROVY PODNIK 15 April 1970 [16 April 1969] 17899/70 Heading H3A The difference in phase between a received and reference voltage, as in a selsyn, is indicated by shaping the received signals, as at 210. producing pulse width modulated pulses in accordance with the phase difference, as at 3, determining the sign of the phase difference, as at 4, and producing an output, as at 6, which represents the phase difference in sign and magnitude. The reference and received signals are available in true and complementary form on leads 221, 222 and 223, 224, respectively. Gate 31 provides an output comprising a pulse train width modulated according to the phase shift between the true signals. Gate 32 provides a pulse train width modulated according to the phase shift between the complementary signals and in anti-phase to the output of gate 31. Gate 33 combines the pulse trains to produce a pulse train at twice the frequency of the received and reference signals. The received and reference signals are supplied to the two elements of a bi-stable circuit 400 in circuit 4 the output 442 of which indicates whether the received signal leads or lags, such indication conditioning the output circuit 6 to produce positive or negative output accordingly. The pulse width modulated pulse train from 3 is subjected to inversions at 5, which allows a blocking signal to be applied at 53, and supplies true and complementary versions of the pulse train to the output circuit 6 which gates the width modulated pulses positive or negative according to the sign indication from 4. The received signal may be three phase converted to single phase and its inverse, Fig. 2, not shown.

Convention date, June 17, 1929. Drawings to Specification. [Class 140.] Felt-base floor covering material comprises a felt base impregnated with a bituminous saturant and having a sealing coat containing an alkyd type resin resistant to the bituminous saturant, with a decorative coating applied over the sealing coat. The alkyd resin may be that sold under the registered Trade Mark " Glyptal " formed from glycerine and phthalic anhydride. In an example, a bitumen impregnated felt base has applied thereto a casein size coat, consisting of an aqueous solution of casein with whiting and clay fillers. Over this is applied the alkyd resin coating, and then the decorative coating which may be of the usual composition, and may be applied by printing machines. Alternatively, the alkyd resin may form the decorative coating by the incorporation therein of pigments. The alkyd resin is preferably applied in solution in a volatile solvent. It may be prepared by mixing ethylene glycol, diethylene glycol, glycerine, phthalic anhydride, and drying oil acids obtained from linseed or Chinawood oil, and heating to 180 to 230‹ C. The product is dissolved in an ether of ethylene or diethylene glycol, such as ethylene glycol mono-ethyl ether or ethylene glycol mono-methyl ether, which may be mixed with ethyl alcohol. This is not a solvent for the bituminous saturant, but other solvents such as ethylene di-chloride, which have some solvent action upon the bitumen, may be used. Where oil paint is used as the final coating, the alkyd resin is preferably modified so as to dry slowly by increasing the proportion of drying oil acids. An alkyd resin formed by condensing molecular proportions of glycerine and phthalic anhydride, together with 50 to 75 per cent of drying oil acids, may be used, or other resins made from various polyhydric alcohols or mixtures thereof and polybasic acids.
