Title: Phase comparator systems
IPC: H04N9/455
Filed: 1954-11-23
Abstract: 757,968. Automatic phase correction. PHILCO CORPORATION. Nov. 23, 1954 [Nov. 24, 1953], No. 33891/54. Class 38 (4). [Also in Group XL (c)] A phase discriminator comprising a product demodulator is supplied with two carrier frequencies for comparison, one of which is amplitude modulated by an asymmetrical signal, a component of the output at the modulation frequency being applied to a bipolar detector to give a signal whose amplitude and polarity depend on the magnitude and sense of the relative phase of the carriers. The invention is described with reference to the stabilization of a colour signal demodulator in a television receiver. In one embodiment, Fig. 2, bursts of colour subcarrier separated from the main carrier are applied to grid 34 of valve 30 and an output from the colour demodulation oscillator is applied to grid 38 through a 90 degrees phase shifter. When the oscillations are phase shifted the valve 30 produces inter alia a signal which depends on the sense and magnitude of the phase difference. This signal is applied, through a rejector circuit 58, tuned to the input frequencies, to diodes 62, 64 to produce at the output 18 of low-pass filter 76, 78, 80 a D.C. signal to control the oscillator. In a second embodiment, Fig. 3, pulses derived from the horizontal sync. pulses are applied over delay line 136 to gate triode 110 conductive only during reception of the colour sub-carrier and it thus behaves also as the burst separator. The oscillator signal is applied over condenser 142 to the control grid of triode 118 coupled in cascode to triode 110 so that signals as before are produced, the required signal being applied to the control grid of triode 150 forming part of the limiting amplifier 102. The amplified signal passes from load 172 to peak detectors 174, 178 and a control potential is produced at the output of low-pass filter 188, 190, 192. It is stated that the product demodulator may alternatively comprise a single triode or diode operating under square law conditions.

Title: Improvements in or relating to the production of resin filled sheet-like material
Inventor: DUNBAR CHARLES
IPC: C08L67/06
Filed: 1954-11-25
Abstract: 817,891. Fabrics coated with polyester compositions. WINTERBOTTOM BOOK CLOTH CO. Ltd. Feb. 24, 1956 [Nov. 25, 1954], No. 34135/54. Class 140. A flexible air impermeable coated fabric comprises a single-ply or sheet of a textile fabric coated and impregnated with a polyester composition, as defined, which is subsequently cured. The term " textile fabric " includes fabrics made from natural and synthetic yarns and filaments, fabrics formed from glass yarns or filaments and pulp or paper. " Polyester compositions " are defined in the Specification as polymerizable liquids which on curing will form an addition polymer and which are capable of setting to a clear transparent sheet comprising essentially a polyester proper, i.e. a condensation product of a dibasic acid and a dihydric alcohol, one of which at least is unsaturated, and a monomeric vinyl compound which is preferably an ester, e.g. ethyl acrylate, methyl acrylate, vinyl acetate or; acrylonitrile or styrene. The coated fabrics of the invention are suitable for use as tracing cloths after the further application of a layer which is sensitive to pencil and/or ink markings, e.g. a nitrocellulose or resinous coating containing an abrasive, or as a reproduction cloth if the further layer contains a light-sensitive composition, e.g. gelatine containing a silver halide. Or the fabrics are useful as coverings, curtains, or diaphragms for pumps. The flexibility and elasticity of the coated fabric may be adjusted by the choice of components from which the polyester proper is made. Thus saturated dicarboxylic acids may be used in conjunction. with maleic acid so that the distance between successive unsaturated linkages in the polyester molecule is increased producing greater elasticity of the product. Also, dihydric alcohols with chain, lengths between the hydroxyl groups greater than that in ethylene glycol or diethylene glycol may be used to produce greater elasticity. The fabric base is coated with the polyester composition and a temporary laminate formed by placing it between two impervous sheets of a material such as " Cellophane" (Registered Trade Mark). This assembly is then passed through a heated oven whereby the coated fabric is cured and then the impervious sheets are stripped off Specification 767,502 is referred to.

Title: Improvements in and relating to substituted oxazolidones
IPC: C07D263/22
Filed: 1957-11-05
Abstract: Oxazolidones of the general formula: <FORM:0866061/IV (b)/1> wherein R represents an alkyl or hydroxyalkyl group having 1 to 4 carbon atoms are prepared by reacting a secondary aliphatic amine of the general formula CH3CH(OH)CH2NHR with CO2 at a temperature of from 120 DEG  to 175 DEG C. at a pressure of from 175 to 700 p.s.i.a.  The reaction may be effected in the presence of a diluent e.g., water or diethylene glycol.  In practice, the carbon dioxide may be added to the amine yielding the amine carbonate or carbonate salt depending on the presence or not of water and these salts under the specified reaction conditions decompose into amine and CO2.  The required pressure may be mostly derived from decomposition of the carbonate salt in a closed vessel or by imposition of CO2, N2 or other gas.  In Examples: (1) an aqueous solution of N-methyl isopropanolamine in an autoclave is saturated with CO2 under pressure and the resulting amine carbonate solution is then heated at 160 DEG C. under 600 p.s.i. CO2 pressure; 3: 5-dimethyl oxalidone-2 is recovered by distillation and purified by cationexchange resin treatment and in like manner there are prepared (2) 3-(2-hydroxy propyl)-5-methyl-oxazolidone-2 from di-isopropanol amine, (3) 3-ethyl-5-methyl oxazolidone-2 N-ethyl isopropanolamine and (4) 3-butyl-5-methyl oxazolidone-2 from N-butyl isopropanolamine. The oxazolidone wherein R = 2-hydroxyethyl is mentioned.  The N-hydroxy-alkyl oxazolidones may be used as selective solvents for the removal of aromatic hydrocarbons from their admixtures with aliphatic hydrocarbons.
