Abstract: 378,182. Regulating ignition &c. DODSON, E., 66, Lewin Road, Streatham, London. July 23, 1931, No. 21062. [Classes 7 (iv) and 7 (vi).] Aircraft engines having means for automatically advancing or retarding the ignition according to changes in induction-pipe pressure due to movements of the throttle valve are provided with additional aneroid means for superposing a further adjustment of the ignition timing in proportion to the density of the atmosphere. In the form shown in Fig. 1, the ignition regulating device h<1> is adjusted through linkwork e, f, h by a diaphragm d<1> in communication by a pipe c with the induction pipe a, and the lever f has a further connection f<4> to the relay piston g<12> of an altitude control g<1>. This comprises an aneroid connected to one end of a lever g<6>, which is also attached at g<7> to a piston valve g<8> controlling the flow of oil to and from opposite sides of the piston g<12>, the rod g<10> of which is connected to the lever g<6> and to the link f<4>. Fig. 3 shows another form in which capsules il subject to induction pipe pressure through the pipe c are connected by links i3, i<4> and lever j to a valve k controlling a relay piston l<2>, the rod l of which is connected to the lever j and by an extension n to the ignition control. A similar capsule and relay device is controlled by atmospheric pressure and is also connected to the ignition control. The rate of change of ignition timing can be varied by changing the point of attachment of the link i<4> from i<5> to i<6>, or by adjusting the fulcrum of the ignitiontiming lever to which the extension n is connected. In order to obtain a retarding of ignition for starting or idling, the pipe c is connected to the induction pipe at a point a<1>, Fig. 1, just in front of the closed position of the throttle so as to be cut off from the depression on the engine side of the throttle when this is closed. In engines provided with blowers, a cam on the spindle of the throttle valve may be arranged to actuate valves which open the connection c to atmosphere when the throttle is closed, the pipe c leading to the induction pipe on the pressure side of the blower.

Title: Improvements in and relating to electronic number comparing devices
IPC: G06F7/02
Filed: 1950-08-31
Abstract: 674,595. Digital electric calculating-apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 31, 1950 [Sept. 17, 1949], No. 21550/50. Class 106 (i). An electronic device for comparing numbers having a common radix comprises a number of groups, including one, of gridbiased electronic tubes, an anode plate in each tube, the electronic tubes in each group being arranged to compare respectively corresponding digits of the numbers, connections for connecting each group of tubes to a source of voltage potential through a common anode plate resistor, and means for varying the voltages on the grids of the groups of tubes in a predetermined relation with corresponding digits of the numbers to obtain a single predetermined output voltage value in response to an identity of two numbers being compared. In a first embodiment each binary digit of a number to be compared is registered on a flip-flop 16 by applying a voltage to one of the input lines (16a for " one " 16b for " zero "). The output lines 18, 19 of the flip-flop apply to the suppressor grids of valves 1, 2, voltages of opposite polarity (18 negative and 19 positive when the digit is " one," and vice versa when the digit is " zero "). A series of binary signals are applied to a second flip-flop 17 for comparison with the registered digit; in this case a " one " on the input 17a flips the device 17 to a condition in which a negative voltage is supplied to the control grid of the valve 2, and a positive to the control grid of valve 1; these voltages are reversed when a " zero " signal on the line 17b triggers the flip-flop 17. The valves 1, 2 have a common anode load 5 and each conducts only when both its grids (7, 9 or 12, 14) are made positive. When either valve conducts the potential of the point 23 falls and a negative output pulse appears on the line 22. Agreement is indicated when both valves remain cut off and there is no drop in voltage at the point 23. By employing three-state devices in place of the flip-flops 16, 17, and three valves having a common anode load, numbers represented on the ternary scale may be compared. In this embodiment, Fig. 2 (not shown), a voltage inverter is employed in the output channel. Binary and ternary units, as described above, are built up to form comparing devices for higher radices in two further embodiments. Their uses in a predetermined counter and in carrying out a high-speed search for a particular number in a large quantity of numbers, is described.
