Title: Closed-loop mixture control system for an internal combustion engine with exhaust gas circulation
IPC: F01M13/00
Filed: 1976-06-09
Abstract: 1510405 Automatic control of engine exhaust NISSAN MOTOR CO Ltd 9 June 1976 [ 9 June 1975] 23822/76 Heading G3R [Also in Division F 1] An I.C. engine in a road vehicle has a three-way catalytic converter 7 for its exhaust, a proportion of exhaust gas is recirculated, and the air/fuel ratio is controlled in response to an exhaust component sensor 3. The signal from the latter is compared with a reference and the result applied to a proportioned and integral controller 4 to adjust a carburetter 5. Exhaust recirculation is controlled by Venturi depression and is via a conduit 9 which may be closed by a valve 10b at low engine temperature, measured at 13. The ratio control signal is clamped at a rich value when the engine temperature is low, the engine is idling (detected by gear neutral switch 14 and throttle closed switch 15a) or at full throttle (switch 15b). Also at low temperature the ignition is retarded by blocking the normal vacuum advance device. To prevent excessive vacuum when the throttle is "snapped shut" a device 20 provides some opening, under the control of vacuum and engine speed detector 22. Fuel evaporated from tank 24 is collected at 25 and stored in a carbon filled canister 27, from which it is fed to the engine under vacuum control. The air/fuel ratio is also adjusted in response to an altitude detector 33. The catalytic converter may be externally heated from the exhaust pipe. In a modification, Figs. 2 and 3 (not shown) an "abnormallity detector" cuts out the proportional channel, disables the integrating channel (to produce a "rich" control signal) and blocks the exhaust recirculation if (i) the converter temperature is too high, (ii) the exhaust gas temperature is too low for the oxygen sensor to operate, (iii) speed is high and throttle is closed for (iv) the oxygen sensor output is high or low for longer than a prescribed time. In another modification, Figs 4 and 6 (not shown) the mixture is enriched and the recirculation is blocked at low engine temperatures by transistor circuits which modify the reference value for the oxygen sensor inversely as the temperature until a set value is reached.

Abstract: 589,666. Cleaning metals. GARRINGTON & SONS, Ltd., J., and SHARMAN, J. C. Dec. 8, 1944, No. 24569. [Class 82 (ii)] [Also in Group XXII] The ends of a steel billet are rectified before drop forging or hot pressing by subjecting the billet to a preliminary endwise compression between dies so arranged as to flatten the ends of the billet and to bring the axis of the billet into accurate perpendicularity with both such ends. The lower die 8 has a shallow recess 9 in which seats the end of the billet 7 which has been cropped from a bar. The upper die 5 is formed with a comparatively deep recess 6 having a taper of not more than 20‹. As the upper die descends, the tapered wall of the recess 6 will engage and tilt the billet as shown in Fig. 2 and will finally compress the billet so that its ends are flat and accurately at rightangles to its axis as shown in Fig. 3. The compression serves to loosen the scale from the surface of the billet and scale so loosened is removed by an air blast from a nozzle 14.

Temperature distribution in the rotor of a turbo-alternator is made uniform by using a three-phase exciting winding 3 by means of which the flux is caused to rotate slowly with respect to the rotor. The necessary low-frequency polyphase current may be supplied, as shown in Fig. 1, by three separate exciters 10, 11, 12 cyclicly excited by mechanical means. Alternatively a three-phase induction regulator or a single commutator generator having three pairs of brushes and poles, may be used. As shown, however, a machine having three poles and three bushes is used (see Fig. 3). The poles may be separately excited, but as shown are arranged for self-excitation. The basic excitation is provided by series windings B1, B2, B3 between the brushes b1, b2, b3 and the rotor terminals R, S, T. Regulated shunt windings A1, A2, A3 serve to control the degree of field excitation of the machine, while regulated additional windings C1, C2, C3 connected to the opposite brushes serve to produce a controlled rotation of flux in the exciter, and so in the rotor of the main machine. If desired these windings may be connected between terminals R, S, T.

Abstract: 1,205,461. Automatic temperature control. CATERPILLAR TRACTOR CO. May 23, 1968 [June 19, 1967], No.24661/68. Heading G3R. A thermally sensitive component, e.g. an electrolytic potentiometer or a thermocouple, is maintained at a constant temperature by controlling the current flow through a power transistor in dependence upon temperature variations as detected by a thermistor, the transistor being thermally associated with the component. As shown, a power transistor 11 is energized from a battery 11 and is arranged to supply heat to an electrolytic potentiometer (not illustrated); the temperature of transistor 11 is sensed by a thermistor 12 connected in circuit with resistors 22, 24 and a Zener diode 23; when the sensed temperature exceeds a limit determined by the value of resistor 24 and the breakdown value of a second Zener diode 25, a control transistor 13 conducts to cutoff transistor 11 which then cools down until it is again rendered conductive by the cutting-off of transistor 13 in response to the resulting fall in temperature. This cycle continues to maintain the potentiometer at the desired temperature. All the circuit components, including the electrolytic potentiometer, may be mounted on a printed circuit board and encapsulated in resin, Figs .1 and 2 (not shown).
