Title: Digital processing of fsk and psk signals
IPC: H04L27/233
Filed: 1965-08-20
Abstract: 1,124,743. Data transmission systems. ROBERTSHAW CONTROLS CO. 20 Aug., 1965 [21 Aug., 1964], No. 35869/65. Heading H4P. A frequency or phase shift receiver comprises means for deriving from the received signal a pulse at a predetermined point in each cycle of the carrier, the pulses passing to a pair of AND gates and to a chain of delay units which develop first and second pulses which respectively enable the gates, the end of each first pulse being spaced a preset time from the beginning of the following second pulse. It is arranged that this preset time makes the apparatus non-responsive to frequencies at about the mean of the shift frequencies when receiving frequency shift signals and prevents the gates from passing pulses at undesired times when receiving phase shift signals. The outputs of the gates are applied to a bi-stable circuit whose output represents the binary data which modulated the transmitted carrier. Reference has been directed by the Comptroller to Specification 960,976.

Filed: 1965-08-26
Abstract: 1,112,521. Manufacturing resistors. WESTERN ELECTRIC CO. Inc. 26 Aug., 1965 [1 Sept., 1964], No. 36622/65. Heading H1S. Apparatus for adjusting the resistance of a resistive device by anodizing, comprises an electrolytic anodizing cell, means for testing the resistance of a device within the cell, means for alternately inhibiting the supply of current to the cell so that a resistance test may be effected and permitting current supply to anodize the device, and means responsive to the attainment by the device of a desired resistance to terminate the anodizing. The device to be anodized is an etched thin film resistor 110 of tantalum on a glass substrate 111, the contacts 112 being successive layers of nickel-chromium alloy, copper and gold. The resistor 110 is incorporated as the anode of an electrolytic cell 114 and is also connected in a common arm of two Wheatstone bridges 147, 148 which provide resistance testing means, bridge 147 balancing when resistance 110 equals the lowest acceptable value, and bridge 148 balancing when resistor 110 equals the highest acceptable value. An A.C. source 161, connected to the cathode through a diode 164 supplies anodizing current to the cell during one half cycle and testing current to the bridges during the other half cycle, the value of resistance 110 increasing until an acceptable value is provided at which stage anodization terminates. A mercury wetted relay 18 is connected to the A.C. source 161 so that during anodization half cycles it shorts the outputs of the bridges, and during testing half cycles it removes the shorts so enabling sensing of these outputs by detectors 168, 173. The detectors 168, 173, connected across the outputs of the bridges 147, 148, each comprise an A.C. or D.C. amplifier and a relay, relay 171 controlling contacts 167 and 172, and relay 176 controlling contacts 177 and 178. An indicating circuit includes lamps 182, 183, 184, contacts 172, 177 and 178 and source 161. In a modification of the circuit of Fig. 6 (Fig. 3) only one Wheatstone bridge is employed and a diode is connected across its output to short it during anodization half cycles. In a different circuit arrangement (Fig. 1), an adjustable constant voltage D.C. source (33) supplies anodizing current to the cell through a normally closed contact (34) and a constant voltage, or current, D.C. source (22) supplies testing current to the single Wheatstone bridge, a normally closed contact (36) being connected across the bridge output to short it so that testing current does not reach detector (28). A timing circuit (37) alternately opens and closes contacts (34, 36) to provide several interrupted periods of anodization and testing.

Abstract: 1,171,839. Producing viscose rayon filaments- TEIJIN Ltd. 15 Aug., 1967, No. 37432/67. Heading B5B. Viscose rayon filaments having a high wet modulus are produced by high-speed spinning wherein viscose having a gamma value at the time of spinning of 65-80 and containing cellulose having a degree of polymerization within the range 400 and 700 is extruded at a temperature within the range 35 to 60 C. into an aqueous spinning bath containing 4 to 6% by weight of sulphuric acid, 3 to 6% of sodium sulphate and 0À001 to 0À1% of zinc sulphate maintained at a temperature of, for example, 30 to 60 C. The viscose is characterized in that the relationship between the degree of polymerization of the cellulose contained in it, the cellulose content of the viscose and the total sodium content of the viscose (expressed as the percentage by weight of sodium hydroxide in the viscose) is such as to satisfy both the following formulµ:- wherein #DP is the average degree of polymerization of the cellulose in the viscose, CC is the percentage by weight of cellulose in the viscose and TA is the total sodium content of the viscose expressed as sodium hydroxide. The heating of the viscose to 35 to 60 C. is effected immediately before it is spun. The filaments formed are preferably stretched between first and second godets after being withdrawn from the spinning bath at a stretch ratio of 1À2 to 1À8. The rate of removal of the solvent from the filaments on the first godet over which the filaments pass after being withdrawn from the spinning bath is specified as being 40 to 60% and the filaments are then stretched. The spinning speed is specified to be at least 80 metres per minute using a "horizontal type" spinning machine. The expression "rate of solvent removal" is defined as the rate at which the solvent (the aqueous solution of sodium hydroxide) is expelled from the viscose during the spinning step and is expressed as the ratio of the amount of the solvent removed during the spinning step to the amount of solvent in the original viscose, expressed as a percentage by weight. The ratio is calculated using the formula wherein R represents the ratio, C 2  is the cellulose content of the filament during the spinning step and C 1  is the cellulose content of the viscose. C 2  is determined by washing and centrifuging a sample of the filaments in the gel state, weighing the filaments (A grams), treating the filaments with a dilute aqueous solution of sulphuric acid, and then weighing them (B grams) after washing and drying them. C 2  is then calculated by means of the formula
