Title: Detector for signal peaks of varying amplitude
IPC: H03K5/1532
Filed: 1974-11-06
Abstract: 1488526 Record/replay systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Nov 1974 [9 Nov 1973 (2) 22 Nov 1973] 47982/74 Heading G4C [Also in Division H3] Digital signals read from a punched tape are recorded as return-to-zero pulses on a minature cassette tape recorder and means is provided for checking the validity of the signals read from the magnetic tape. Recording,-8-Bit words on punched tape 82, Fig. 9, are entered in parallel in a shift register 102 and a parity detector 118. Clock signals generated at 106 and divided by two at 107 and 108 are applied to a pulse generator 115 which receives serially the digit stored in shift register 102. Pulse generator 115 comprises an arrangement of NAND gates and voltage dividers, Fig. 11 (not shown), so arranged that when a "1" is applied from shift register 115, the output voltage follows the sequence O, - V, V, O and for a "0" the sequence is 0, V, -V, O. The arrangement of circuits 103-113 is such that an initial synchronizing "1" digit is produced and if the parity detector is satisfied, the clock 106 is inhibited for the period of monostable multivibrator 104. If the parity detector is not satisfied the information bits immediately follow the synchronizing bit indicating an invalid word. Reading of recorded signals.-The "0" and "1" bits in the read out signal are detected by separate peak detectors and fed to a mixer 68, Fig. 13. The circuit 69 gives an output when two successive pulses are missing from the signal and the arrangement of monostable multivibrator 70, differentiator 153 and coincidence circuit 154 sets the flip-flop 155 when there is a gap between the sync. pulse and the word (indicating a valid word). The output from 155 allows the read out signal to be applied to input 165 of a shift register 162 stepped on by the read out signal delayed at 157 and to a counter 160 which counts to the end of the word to enable gate 163 so that the complete word appears in parallel on lines 164. Counter 160 resets the circuit to read the next word.

Abstract: 1363756 Carbon monoxide; nitrogen AZOTE ET PRODUITS CHIMIQUES SA and ONIA-GEGI 15 Oct 1971 [19 Oct 1970] 48178/71 Heading C1A Carbon monoxide and inert gas (i.e. nitrogen containing argon) are produced from liquid or gaseous hydrocarbons by partial oxidation in air in the presence of a catalyst and treating the resultant gas to obtain three fractions, (a) the desired carbon monoxide, (b) carbon dioxide and (c) a residue consisting of hydrogen and nitrogen which is burnt to obtain the inert gas. The partial oxidation is carried out at between 750‹ and 950‹ C. under a pressure ranging from atmospheric to 40 bars and preferably in the presence of steam, the molar ratio of steam to the carbon in the hydrocarbon being 0À5 to 2. As shown, a hydrocarbon CnHm is fed via line 2 into an oxidizer 14 supplied with compressed air from line 1 and compressor 11, steam in line 3 and recycled carbon dioxide from separator 15, via compressor 12 and line 4. The catalyst may be nickel supported on a refractory carrier such as alumina, magnesia or a silico-aluminate. The resultant gases pass to separator 15 which may comprise a washing tower in which CO2 is absorbed in potassium hydroxide or an ethanolamine, and a desorption tower in which the absorbent is regenerated with liberation of CO2. The liberated CO2 is led back to the oxidizer 14 as detailed above. The gas leaving the separator unit is passed to a second separator 16 in which carbon monoxide is absorbed in, e.g., ammoniacal cuprous formate or acetate from which solution the absorbed gas may be recovered. The residual gas, substantially free from oxides of carbon, is passed to a combustion unit 17 where it is burnt with compressed air in a primary chamber and finally in a chamber using a nickel-platinum catalyst without excess of air. The resultant gas is mainly nitrogen but may contain, e.g. 0À5% of argon.

Title: Control Circuit for Latching Relay
IPC: H01H47/32
Filed: 1968-10-11
Abstract: 1,191,082. Relay operating circuits. NORTHERN ELECTRIC CO. Ltd. 11 Oct., 1968 [13 Dec., 1967], No. 48202/68. Heading H3T. Operation or release of a latching relay 10 is effected by a signal applied through a step-up transformer 130 or 230 to the junction of the relay winding and a series circuit including a resistor 12 and the latching contact 10-1. Operation of the relay in the circuit shown is effected by timing pulses at 100 concurrent with signals at 112 and 114. These cause transistors 110 and 116 to conduct and apply the operate pulse through the transformer to the relay, operation being speeded by a series capacitor 146. The back E.M.F. produced at the collector of 116 when it switches off causes a zener feedback diode 126 to conduct and slow the switch-off and thus prevent overswing. Release of the relay is effected by a similar circuit providing an opposite polarity pulse through transformer 230, diodes 114 and 214 preventing interaction between the circuits. The inputs 114 and 116 prevent simultaneous operation of the operate and release circuits. 17 represents contacts connecting the circuit to other relays and the state of the relay may be monitored on line 16.

Should the shift register SRI cease to provide an output, the output of Sc1 is transmitted to provide a standby signal pattern. Under normal conditions of reception, logic unit EL compares the separated monitor signal with a locally generated one, the result SYN passing to a synch monitor. Should realignment be necessary, scrambler Sc2 is stopped, unit EL receiving the scrambled monitor signal for comparison with a corresponding locally generated signal. Scrambling of the transmitted signal avoids bunching in its spectral density. The scramblers may each have as many shift register stages as there are bit positions in the frame control word.

Abstract: 1406630 Making containers; soldering FRANPAC 26 Oct 1972 [2 Nov 1971] 49528/72 Headings B3A and B3R A method of manufacturing a sealed metal container 1 comprising a body (2), Fig. 1 (not shown), and a lid (3) sealed thereto by means of a metal sealing strip 6 overlappig the junction (5) between the body and lid and fixed by soldering comprises rotating the container relatively with respect to the metal strip to coil the strip around the container, the strip being a flexible ribbon provided with at least one strand (7) of solder thereon, attaching one end of the strip to the junction, exerting a continuous traction tangentially to the container on the attached strip, and progressively heating an area situated adjacent a point 13 where the strip meets the container to melt the solder, the soldering being performed over at least the circumference of the junction with the strip being coiled a further distance to provide an unsoldered tear-off tab (6b), Fig. 1 (not shown), at the other end of the strip. The container is mounted between two rotatable mandrels 4. The strip, preferably provided with two parallel strands of solder, is fed from a feed-drum (not shown); passes between jaw grip 8a of a vertically-movable counter-weight 8; passes over a drive roller 10; passes over a guide-piece 12 of a cutting and forming device 11, and is applied tangentially to the container at the junction. A clamp 14 enables the strip to be attached to the container at the beginning of the soldering operation. A torch 15 having nozzles 16 is used to heat the solder and this is followed by cooling when the strip has been attached. The device 11 includes a marking die 18 and a knife 19 to impress the strip end with corrugations and finally to cut it off from the feed. The tab 6a can be attached to the strip by spot-soldering with an electrical pulse electrode (not shown). The mandrels 4 are then moved apart, a retractable dog 27 releasing the container along runway 25, and a dog 26 releasing a fresh container along runway 24. The strip is preferably made of tin plate and the solder is preferably of a lead/tin alloy. Various modifications include using spotsoldering of the strip to the container at the beginning of the coiling and alternative methods of heating the strip, e.g. gas other than oxyacetylene, electrical means. Cooling of the heated zone can be made by passing a cold gas jet through nozzle 28. Adjustable tension rollers could be used instead of a counterweight and the strip could be pre-cut to avoid use of knife 19. The solder could be provided over the whole of the inner surface of the strip, Jaws 8a of the counter-weight could be used for the marking of the tab 6b. The containers may be circular, elliptical &c. or of polygonal shape, e.g. 10 or 12-sided.

Abstract: 1438808 Automatic control of temperature KLOCKNER-HUMBOLDT-DEUTZ AG 30 Oct 1973 [12 Dec 1972] 50414/73 Heading G3R The windings temperature of a motor 1, Fig. 1 driving a processing machine 2, e.g. a crusher plant, is measured by a sensor (not shown) and compared with a desired temperature value in a master controller 3 and which value is less than the max. permissable temp. From the temp. difference the controller 3 derives a desired motor current value and an aux-controller 4 compares it with the actual value of the motor current to produce a desired speed value for a conveyer belt 6 delivering material to the processing machine 2. The desired speed is compared in a controller 5 with the actual speed of the conveyer measured by a tachometer 9. The speed error signal is used to control the belt drive motor 12 speed via a servomotor 7 which adjusts a speed regulating unit 8. Thereby the load on the motor 1 is adjusted and the temp. of the motor 1 is maintained substantially at the desired value.  Sudden abnormal increases in measured temperature result in switching OFF the conveyer belt drive motor 12 by switchgear 10. A unit 13 limits the output of the master controller during cold starting. In a modification Fig. 2 (not shown) the measured actual current signal is converted by an analogue computing circuit 14 into a motor power loss (I<SP>2</SP>R) signal which is smoothed and applied to the auxiliary controller 4 and helps to compensate for fluctuations of measuring and comparison values in the control circuit.

As shown, a hand-held air-powered nut-setter comprises a socket 10 driven through a gear-box 16 by an air motor 11. The torque applied to the socket is detected by a D.C. energized bridge transducer 17 and the output, through a pre-amplifier 21 stored in a peak signal memory 22. The value in memory 22 is compared with a torque reference signal from a potentiometer 27 by a level detector 31. At equality the detector actuates a solid-state power switch 30 which de-energizes a solenoid 14 thereby opening an air-valve 13 controlling the supply to the motor 11. The memory is reset and solenoid energized for the next operation by the manual closure of switches 32, 34. Capacitors 25 limit the system response to rapid torque changes. In modifications (a) the memory is replaced by a flip-flop and (b) motor torque is pulsed to limit the reaction on the operative, the duration of a torque pulse decreasing with increased amplitude. It is stated that the electric control can be replaced by an equivalent fluidic control.
