Title: Combination of an air-pollution preventive arrangement and an exhaust system of an ic engine
IPC: F01N13/02
Filed: 1971-06-28
Abstract: 1356203 Purifying exhaust gases NISSAN MOTOR CO Ltd 28 June 1971 [8 July 1970 19 Oct 1970] 30096/71 Heading F1B An I. C. engine exhaust purifying system for removing hydrocarbons and carbon monoxides from the exhaust gases, comprises a thermal reactor 12, Figs. 7 and 9, a downstream catalytic converter 13, and means for supplying additional air to the exhaust gases at locations upstream of the reactor and immediately upstream of the converter. In one form, Fig. 5 (not shown), an air pump supplies air to the exhaust gases through branches having restricted orifices (20a, 21a) therein. In the embodiment shown in Fig. 7, the proportion of air delivered through branches 20, 21 is controlled by a slide valve 24 in accordance with the air-to-fuel ratio of the combustible mixture supplied to the engine, the ratio being measured in terms of intake manifold suction or suction at the carburetter Venturi, and of temperatures in the reactor and converter. These suction and temperature values are supplied in the form of electrical signals to a modulator 33 which causes appropriate actuation of a reversible motor 31 to adjust the valve 24 via worm 27 and wheel 28. Means in the form of a potentiometer mounted on the wheel 28, or as shown a rheostat 35, delivers a feedback signal to the modulator to stop the motor 31 when suitable adjustment of valve 24 has been made. The valve 24 may completely shut off branch 21 during engine deceleration. Alternatively the branch 21 may have a solenoid valve 37, Fig. 9, for this purpose, the valve 37 being de-energized by diaphragm-actuated switch 38, 39 to close the branch 21 when the intake manifold suction exceeds a predetermined value due to engine deceleration due to loading. The diaphragmactuated switch 38, 39 may be replaced by one mechanically connected with the carburetter throttle valve (41), Fig. 10 (not shown). An additional catalytic converter, primarily for nitrogen oxides, may be provided between the present reactor and converter.

Title: Facsimile transmission system
IPC: H04N7/167
Filed: 1960-09-02
Abstract: 906,353. Copying telegraphy. STANDARD TELEPHONES & CABLES Ltd. Sept. 2, 1960 [Sept. 3, 1959], No. 30362/60. Class 40 (3). A facsimile system comprises means for transmitting a signal representative of intelligence which, for reasons of privacy, is contained in an enclosure which is opaque to light and means for receiving the signal and converting it back to intelligence at a remote point. In the case of written intelligence the copy to be transmitted is prepared by writing on paper placed on top of second paper coated with a substance opaque to X-rays, e.g. barium. In this way the copy has transferred to it a barium mirror image of the writing. The message, in an opaque envelope 4, is placed between an X-ray scanner 5 and a scintillation counter 6. The X-ray beam scans in a raster, the beam passing through the envelope 4 to the counter 6 except where it encounters the barium trace. The resultant signals from the scanner, together with the scan synchronizing signal, is transmitted by unit 8 and received at a remote point by unit 9. The synchronizing signals are separated by unit 10 and the facsimile signals passed to a second X-ray scanner 11. An opaque envelope 13 contains an X-ray responsive paper so that the intelligence is reproduced thereon when scanned by the beam from scanner 11. A coding device 14 may be incorporated at the transmitter, if desired, a corresponding decoding device 17 being provided at the receiver. As the scanning of one message takes place during a single raster scan less transmission time is wasted if a number of messages are sent in sequence, each message being contained and received in its own opaque envelope. This is done by using a plurality of channels each comprising X-ray scanners and associated equipments as described above, Fig. 2 (not shown), there being a distributer to switch synchronizing signals to each channel in turn to scan the message in that channel. Automatic means may be provided for removing a message which has been transmitted and for replacing it with a new message. If no new message is available the channel is rendered inoperative automatically.

Abstract: 1,084,947. Testing pumps. MARQUETTE CORPORATION. July 20, 1965 [July 20, 1964], No.30816/65. Heading F1A. A test instrument for fuel pumps comprises a passage having a throttle and a manually operable valve, and a pressure gauge 15 connected to the passage upstream of the valve. The gauge 15 indicates vacuum or pressure according to the connections to the pump. The rate of flow from the pump is measured by keeping the valve open, the gauge then indicating the pressure drop across the throttle, which is downstream of the gauge. For measuring the suction or output pressure of the pump, the valve is closed by depression of a button 52. The valve comprises a spring- loaded diaphragm engageable with a valve seat incorporating the throttle, Fig. (not shown). The pressure gauge connection incorporates a porous insert, e.g. of sintered bronze or porous plastic, to damp pressure pulsations.

In a pulse-echo system for testing electric cables, electric pulses are applied in parallel to the grids of two cathode followers VI and V2 whose cathodes are connected to the grid and cathode respectively of an amplifier V3 coupled to a cathode-ray oscilloscope (not shown), the cathodes of V1 and V2 being also connected respectively to the cable 1 under test and to a matching network 3 which has substantially the same electrical properties as the cable 1 over the frequency range of the test signal so that the input signal balances out at the amplifier and produces little or no output signal, thereby preventing overloading of the amplifier, whereas the echo signal, being applied to the grid only, produces an output signal. The cathode followers may be balanced by adjusting the grid bias of one of them and by adjusting a differential condenser C1 connected between both grids and earth; these adjustments are also effective in compensating small differences between the matching impedance 3 and the cable 1. When it is desired to apply attenuated input pulses to the indicator, the cathode followers should be slightly unbalanced.
