Patent GB-1045713-A (GB)
Title: Draught regulator for boiler furnaces
IPC: F23N3/08
Filed: 1963-06-13
Abstract: 1,045,713. Automatic temperature control. ELECTROAKTIEBOLAGET MICATRONE. June 13, 1963 [July 6, 1962], No.23516/63. Heading G3R. [Also in Division F4] An electric motor linked to a rotatable damper in an exhaust outlet pipe of a boiler furnace, Fig. 1 (not shown), is automatically controlled in response to the furnace combustion chamber suction to maintain the latter at a predetermined value during normal furnace operation. The suction is transmitted to a chamber 60, Fig. 4, bounded by a diaphragm 58 which moves an arm 72 so that one of two opposed contacts 73, 74 engages one of two fixed contacts 76, 78 so that through the transistorized amplifying circuit shown and either relay R4 or R5 the electric motor is energized to either partially close or open the damper through contacts M1,M3 or M2, M3 respectively. When starting the furnace, the circuit of Fig. 3 (not shown) is operative. A thermostat linked across contacts F1 F2 energizes a relay R1 which energizes the motor to open the damper through contacts M2, M3. A cam operated switch (not shown) connected across contacts M4, M5 and attached to the motor spindle is closed when the damper reaches its fully open position thus energizing a relay R2 and a starting relay (not shown) which is connected over contacts F3, F4, F5 and which ignites an oil burner of the furnace. As soon as the burner starts, a relay R3 is closed and causes the control circuit of Fi. 4 (indicated in dot-dash line 56 of Fig. 3) to become operative.
Patent GB-442869-A (GB)
Title: Manufacture of substituted aromatic amino-compounds
Filed: 1934-08-15
Abstract: Substituted aromatic amines are made by causing an azo dyestuff of the formula <FORM:0442869/IV/1> where R=a residue of the benzene or naphthalene series, to react at an elevated temperature and advantageously under raised pressure with an alkali metal salt of a compound of the formula R1--SO2H where R1 = alkyl, aryl or aralkyl, and splitting up in known manner the azo dyestuff thus obtained.  The addition of copper is advantageous in some cases.  In examples: (1) the dyestuff o-chlor- or o-bromaniline --> salicylic acid is heated with benzene sulphinic acid in presence of copper powder and the product (identical with the dyestuff 2-aminodiphenylsulphone --> salicylic acid) is reduced to 2-aminodiphenylsulphone; (2) and (10) 2-amino-3 : 4<1>-dimethyldiphenylsulphone is made by treating the azo dye 3 - chloro - 2 - toluidine --> o - cresotinic acid with toluene-p-sulphinic acid in aqueous solution or in nitrobenzene in presence of copper powder and reducing; (3) 2-amino-5 : 4<1>- and 4 : 4<1>-dichlorodiphenylsulphones are made by treating the azo dyes 2 : 4- or 2 : 5-dichloroaniline --> phenol with p - chlorobenzenesulphinic acid and reducing; 3-methyl-5 : 4<1>-dichloro - 2 - aminodiphenylsulphone is made by similarly treating the azo dye 3 : 5-dichloro-2-toluidine --> phenol in the presence of copper powder and reducing; (4) 2 : 6-di(methylsulphone)-1-aminobenzene is made by condensing the azo dye 2 : 6-dichloraniline --> o-cresol with methanesulphinic acid sodium salt and reducing; (5) 2-amino-5-methoxyphenylethylsulphone is made by condensing the potassium salt of the azo dye 3-chloro-4-amino - 1 - methoxybenzene --> 1 - naphthol or its 7-sulphonic acid with ethanesulphinic acid sodium salt and reducing; (6) and (7) 3-methyl-2-aminodiphenylsulphone is made by condensing the disodium salt of the azo dye 3-chloro-2-toluidine --> salicylic acid with benzenesulphinic acid in the presence of copper powder in aqueous or amyl alcohol solution; (8) o-aminophenylmethylsulphone is made by condensing the azo dye o-chloroaniline --> salicylic acid with methanesulphinic acid sodium salt as in (7) and reducing; (9) 3-methyl-2-aminophenylethylsulphone is made by reducing the condensation product of the azo dye 3-chloro-2-toluidine --> salicylic acid (sodium salt) and ethanesulphinic acid sodium salt; (11) 3-methyl-2-aminophenylbenzylsulphone is made by treating the disodium salt of the azo dye 3-chloro-2-toluidine --> salicylic acid with benzylsulphinic acid and reducing.

Title: Contacltess ignition apparatus for internal combustion engine
IPC: F02P5/155
Filed: 1974-05-29
Abstract: 1471310 Timing ignition HITACHI Ltd 29 May 1974 [30 May 1973] 23776/74 Heading F1B A pair of pick-up coils 1 and 2 detect ignition retard and advance instant signals respectively, and are utilized selectively to discharge a capacitor 5 to energize a monostable multi-vibrator 17 controlling amplifying and power transistors 18, 19 in the primary ignition coil circuit. The selection of advance or retard is effected in accordance with the running conditions of the engine. For ignition retard, an external signal is applied to a terminal 7 rendering a transistor 8 conductive and transistor 6 non-conductive, so that the output at coil 2 is rendered inoperative. Immediately prior to the retard signal, the pickup 1 produces a negative pulse turning off transistor 3 and initiating charging of capacitor 5. At the retard signal, transistor 3 is switched on and capacitor 5 discharges. When the running conditions require ignition advance, the external signal at terminal 7 is absent, so that transistor 8 is switched off and transistor 6 switched on. A negative pulse from pick-up coil 2 switches transistor 6 off, and the next instant the negative pulse from pick-up 1 switches transistor 3 off so that capacitor 5 charges up until the pick-up coil 2 produces a positive pulse to switch-on transistor 6 and discharge the capacitor. Again, Fig. 3 (not shown), an additional transistor (10) is connected with its collector to the base of transistor 3 and its base to power and to the collector of transistor 8. Thus, when operating for ignition advance, transistor 3 is switched off continuously, and pick-up 1 plays no part. Also, Fig. 4 (not shown), terminal 7, is grounded and the base current of transistor 8 is controlled by a switch (23) opened only during ignition retard. In Fig. 5 (not shown), the output of either pick-up coil may be cut off directly by means of field effect transistors (24), (25), and an external retard terminal 26. The running conditions of the engine is detected by the temperature of the cooling water, revolutions per minute, accelerator pedal position, vehicle gear selected, inlet manifold depression, and opening of the throttle.

Class 37 A differential accelerator circuit for correcting the indications of an electric measuring circuit having a substantial delay in establishing an accurate reading comprises a differentiating circuit rapidly responsive to rapid variations of the value of the quantity to be measured which is operative to vary the indicator reading in a direction corresponding to a variation of the measured quantity at a time earlier than that at which the indicator would otherwise have been operated by the measuring circuit ; the response of the differentiating circuit being dependent on the rapidity of the variation of the measured quantity. In a telemetering circuit CBT of the kind 'described in Specification 629,245, responsive to the impulsing of load measuring contacts MC, the lagging indications on the meter IM are corrected by adding in a rate signal derived from a current transformer CT coupled to the load circuit, whose output is rectified to unidirectional pulses corresponding to sudden load changes, which are differentiated in the circuit C1, R1, R2, R3, and applied to the grid of the Miller effect pentode V1 of a circuit CBC which is similar to the foregoing circuit CBT except that the smoothing circuit is omitted and the pulse is fed in from a differentiating circuit instead of from a changeover contact. The output of CBC is superimposed upon that of CBT in the meter IM so that on increase of load the circuit CBC provides a rapid positive-going pulse correcting for the slower response of the circuit CBT, and vice versa on a decreasing load.
