Filed: 1970-02-25
Abstract: 1280803 Measuring frictional force electrically XEROX CORP 25 Feb 1970 [26 Feb 1969] 9045/70 Heading G1N [Also in Division H4] In an apparatus monitoring the distribution of electric charge or potential on the surface of a selenium photo-conductor 24 supported on an earthed, conductive drum 26, a probe 22 in a rubber mounting 21 bears on the surface of the selenium and the frictional force between the probe and the selenium varies, as the drum rotates, in accordance with the charge distribution (Johnson- Rohbek effect), so that the probe flexes correspondingly to vary the capacitance it forms with a plate 23. The capacitance is part of the frequency determining circuit of an oscillator 31. The apparatus is applied to a coincidence detection system Fig.5 (not shown) wherein a photo-conductor (54) is uniformly electrostatically charged by a corotron (53) and a selected area of the photoconductor is completely discharged by exposure to light systems (44, 47, 49, 52) and (43, 46, 48, 51) sequentially, which exposure is detected by probe (22), capacitor plate (23) and oscillator circuit (31). Alternatively the time lapse between signals to light sources 43 and 44 respectively may be measured using the apparatus. In Fig.4 a document 50 to be reproduced is illuminated by strobe lamps 38, 39 and an image is focused by a lens 41 on to a photo-conductive belt 40 with a conductive backing, which image produces a latent electrostatic image, the belt is charged by a corotron 30 and the charge pattern is detected by the probe 22 as the belt is translated past it, the resultant output signal being transmitted to a unit 42 for recording, processing or use.

Title: Closed loop mixture control system using a two-barrel carburetor
IPC: F02D41/14
Filed: 1976-03-09
Abstract: 1503845 Spray carburetters NISSAN MOTOR CO Ltd 9 March 1976 [24 March 1975]  09302/76 Heading F1H [Also in Division G3]  A closed loop mixture control system, for a road vehicle I.C. engine, comprises a two-barrel carburetter the primary barrel of which has a smaller cross-sectional area than the secondary barrel, the secondary barrel being adapted to begin to operate when a predetermined value of depression is reached in the primary barrel Venturi, means for producing a control signal representing the difference between the air/fuel ratio of the mixture supplied to the engine and the air/fuel ratio of a stoichiometric mixture a primary metering system associated with the primary barrel and responsive to the control signal to maintain the air/fuel mixture ratio at the stoichiometric ratio. Secondary barrel 7 has a main nozzle 9b and an associated air bleed 23a; and a slow-running port 22a with an associated air bleed 23b. Secondary throttle valve 10b is actuated by a diaphragm motor when the primary barrel Venturi depression reaches a threshold value. Primary barrel 6 has a main nozzle 9a, an air bleed 13a and an additional air supply passage 14a controlled by valve 18a. There is a slow-running port 12a with an air bleed 13b and an additional air supply passage 14b controlled by valve 18b. Valves 18a and 18b are selectively actuated by a relay contact ri which, in conjunction with an engine speed sensor, selects valve 18b at slow speeds and valve 18a at higher speeds. Control circuit 17 receives, from exhaust gas sensor 15, a voltage signal representative of the oxygen concentration in the exhaust gases and provides a pulsed output signal in which the pulse width is proportional to the input voltage, so that the ratio of open time to closed time of the valve 18a or 18b is appropriate to produce a stoichiometric mixture. Control circuit 17 consists of a comparator 30, Fig. 3, in which the signal from sensor 15 is compared with a reference signal, a proportional-integral controller 32, a pulse width modulator 34 and a driver stage 38. Two pulse generators 35 and 36 are selectively connectable to modulator 34 and operate at different frequencies, sufficiently far removed. from the slow and high engine speeds to prevent resonance and instability. In a modification of the control circuit to avoid an abrupt change in the feedback loop when changing from pulse generator 35 to pulse generator 36, two comparators 41 and 42, Fig. 4, are used, connected respectively to relays A and B. At low engine speeds, valve 18b is energized; an engine speed sensor or throttle position indicator is connected to both comparators and at medium engine speed comparator 41 produces an output which energizes relay A so that both valves 18a and 18b are energized. At higher speeds, comparator 42 energizes relay B so that only valve 18a is energized. The maximum ratio of primary barrel cross-sectional area to secondary barrel crosssectional area is 1:4.

Abstract: 1419827 Photographic apparatus DR-ING RUDOLF HELL GmbH 27 Feb 1973 [29 Feb 1972] 9578/73 Heading G2A In apparatus for loading and removing film material from a drum, film material is carried on a tiltable frame in a light proof cassette; an opening in the cassette is sealable to an opening in a housing surrounding the drum and the frame is tilted to transfer the material from a register strip on the frame to a register strip on the drum; the material is transferred from the register strip on the drum back into the cassette through the sealed openings. In operation after the cassette opening 7 has been light tightly sealed to the housing opening (not shown) a lever 10 is operated to move a shaft 11 so that a friction wheel 32 driven by a reversible motor comes into contact with the drum I and rotates it in the direction of the arrow 35. The movement of shaft 11 also brings a pin 25 mounted on a lever 24 into engagement with the periphery of a cam 26 mounted on the shaft 5 of drum 1. When pin 25 engages in a cut-out 36 in the cam it stops the rotation of the drum at a point at which the drum register strip, which comprises three pins 2,3,4, is opposite the connected openings. The engagement of pin 25 in cut-out 36 also causes shaft 11 to rotate and tilt the frame 9 via cam 41, pin 42, lever 43 and rod 44 bringing the frame register strip which comprises three pins 38, 39, 40, and on which the film is carried, into registry with the pins on the drum. The pins 39, 40 are spring-biased, see Fig. 4, and as they press against the drum pins they retract, transferring the film to the drum pins which hold the film in position by balls 50, housed in the pins and biased by a spring 202, Fig. 7. The drum is again rotated to withdraw the film from the cassette, the film being held against the drum by suction holes 101 in undulating channels 102. After exposure of the film lever 10 again operates shaft 11 to rotate the drum in the reverse direction (arrow 51) by wheel 32 and to bring a blade 62 into engagement with the drum. The blade peels off the exposed film and directs.it back into the cassette. The cassette opening is then sealed by a slide 8 and the cassette removed for the film to be developed.
