Abstract: 598,427. Dust filters. HUTCHINGS, H. R. Sept. 3, 1945, No. 22646. [Class 8 (ii)] In a dust collector of the type Comprising one or more filter bags 6, Fig. 1, cleaned by a counterflow of air controlled by valves 7, 8, Fig. 2; actuated by cams, which latter also serve to shake each bag in turn, periodic counterflow of air and shaking is effected by a dual cain 11a having a section of bag-shaking teeth 15 and a valve operating section 16 tending to hold the valve 7 Open and 8 closed ; the valves 7, 8 being loaded so that when the bags are in use as filters 7 is closed and 8 open. In operation, dustladen air from an inlet 10 passes from a chamber 5 through the bag walls to a chamber 4, and past the open valve 8 to a suction manifold 9, On reversing the valves 7, 8, fresh air passes the valve 7 to the chamber 4 and through the bags to join dust-laden air about to traverse an adjacent group of bags, the shaking of and direction of air flow through which are controlled by a separate dual cam mounted on the same spindle 13. The shaking mechanism comprises spaced pivoted plates 17 which, when the teeth 15 engage a pin 19 joining them, rock and oscillate the bags to which the plates are connected by a rod 21 pivoted at 20. The valves are actuated when part-circular profiles 16a of the cam 16 contacts a blocks 28 secured to a spring-loaded rod 24 connecting the valves 7, 8. In a modification, the segment 16 is arranged periodically to depress and hold against gravity one end of a rocking lever whilst the teeth 15 oscillate a second lever having a pivot common to the first lever to effect shaking of the bags. The valves are of the gravity-loaded disc type.

Patent GB-1389302-A (GB)
Title: Multiplexing system
IPC: H04J3/16
Filed: 1972-05-16
Abstract: 1389302 Multiplexing and pulse code modulation system TEXTRON Inc 16 May 1972 22891/72 Heading G4H In a voice communication system having a plurality of input channels, which are successively sampled and the samples converted to digital signals, the digital signals have a form in which the signals with the highest probability of occurrence have the smallest number of ones. The digital signals from a sample of each channel are combined into a format and a series of digital location munbers identifying the position of the ones in the format are generated. These location numbers comprise less bits than the signals making up the format and are transmitted. The corresponding receiver comprises complementary means for recontracting the format and the voice input signals from the location numbers. As shown, in simplified form in Fig. 9, 60 input voice signals are sampled and time division multiplexed at 80 and each sample is converted by A/D converter 82 to a five line parallel binary signal in which one line represents sign and the other four the signal level according to the arrangement described above (for details see Fig. 7, (not shown)). The succession of 60 five line signals is fed via switch 88 to one of the 5 parallel 60 stage shift registers 84, 86 while the other passes on signals previously stored therein. The signals from the shift registers 84 or 86 are shifted out serially one line at a time and starting with the most significant figure line while the sign bits are recycled at the same shift speed from output to input. At the transmitter processor, the location numbers are determined by counting the number of digits until a "one" arrives. This number is coded in 5 line binary, the sign bit corresponding to the "one" is coded as a sixth line and the signal is fed to one of the 6 parallel 20 stage shift registers 94, 96. When 30 "zeros" have been counted before a "one", the number 31 plus the corresponding sign bit is recorded and the count restarted. If less than 20 location numbers are generated, the remaining spaces in the register 30 may be filled with 111110 representing 31 zeros or the last space may be filled with a synchronizing signal comprising six zeros. After transmission, the location numbers are received in parallel 20 stage registers 941, 961 and trains of zeros with ones in the position indicated by the location numbers and also the sign bits are fed to the 5 parallel 60 stage resisters 104 or 106. The 60 output channels are then regenerated from the values in registers 104 or 106 by D/A converter 108 and demultiplexer and sample and hold circuits 110.

Title: Hydrogen gauge
IPC: G01N27/12
Filed: 1964-06-03
Abstract: 1,017,937. Measuring hydrogen concentration electrically. UNITED STATES ATOMIC ENERGY COMMISSION. June 3, 1964 [June 26, 1963], No. 22910/64. Heading G1N. The concentration of absorbed hydrogen in a liquid, e.g. water, is determined by the change in resistance of a palladium wire immersed in the liquid. The resistor is also connected to a battery to pass current from it through the liquid, which either forces hydrogen out of or into the palladium, depending on the polarity of the palladium with respect to the liquid. As shown (Fig. 1), two wires 48, 50 are wound on a cruciform-shaped insulating mandrel 12, screwed into a support 10, and covered by a perforated housing 14, the unit being screwed into the wall 30 of a vessel containing the liquid 20 whose hydrogen concentration is to be ascertained. Wire 48 is made of palladium which absorbs hydrogen in solution in the liquid 20, producing a change in the resistance of the wire, which is measured in a bridge circuit 70 to indicate the concentration of hydrogen in solution in the liquid. Wire 50 is made of platinum which does not absorb hydrogen, the wire 50 acting as a reference resistor having the same resistance-temperature coefficient as wire 48. To ensure that the palladiumhydrogen solid solution does not reach un unstable condition, the palladium wire 48 is connected to a battery 82 to pass current from wire 48 through the liquid 20 to the wall 30. When wire 48 is positive with respect to the wall 30 hydrogen is forced out of the wire: the reverse polarity causes the wire to absorb hydrogen. In both cases the liquid 20 must contain a dissolved electrolyte to make it conductive, and in the latter case the liquid 20 must also be capable of yielding hydrogen ions at a palladium cathode.

[Class 7 (iii)] A fuel-injection valve for internal-combustion prime movers, opened by the action of the fuel pressure on a piston connected to the valve, is provided with a stop limiting the opening of the valve and so set as to ensure the valve contacting with it under the injection pressure, a relief valve being provided to open at normal maximum injection pressure. Fuel supplied by a pump 12, Fig. 1, through a passage 19 acts on a shoulder 25 on the injection valve 23 so as to open this a small amount limited by an adjustable stop 31. Atomization then takes place at the valve seating 24, the fuel passing through a passage 33 and being further atomized at the nozzle orifice 21. If the fuel pressure becomes excessive, it escapes past the relief valve 35. The valve is closed when fuel pressure is admitted past a cam-actuated valve 40 to a piston 26 on the injection valve. Fig. 2 shows another form of injection valve 76, in which a cylindrical extension 79 is provided from the valve seat 77 and operates in a passage 81 which tapers down to the orifice 89.
