[Class 106 (i)] [Also in Group XXI] A device for obtaining the elevation angle for anti-aircraft guns comprises a cam body f Figs. 2 and 3, pivoted on an axis a and bearing on a feeler 8'which is displaceable in a longitudinal and transverse direction. The feeler is supported in an inclined position in a sleeve h that is movable transversely by screws e and gearing c in accordance with the horizontal range; the feeler s is screwthreaded and engages a worm wheel d meshing with a worm g slidably keyed to a shaft i rotatable in accordance with the height of the target. The curved surface of the cam body is shaped in accordance with the tangent elevation, the range and height of target so that the feeler by its displacement in the two directions rotates the cam body through an angle equal to the sum of the angle of sight and angle of tangent elevation. The movement of the cam may be applied directly to the gun but preferably the result is indicated on an indicating apparatus.

Abstract: 1,132,979. Iron oxide; ammonium salts. KAWASKI STEEL CORP., and MEIWA CHEMICAL ENG. CO. Ltd. 30 Nov., 1965, No. 50830/65. Heading C1A. Ammonium salts (e.g. sulphate and chloride) and iron oxide (Fe 3 O 4 ) are produced by oxidizing, using air or oxygen, and NO 2  gas as a catalyst, an aqueous solution of a ferrous salt (e.g. sulphate or chloride) containing a free acid (e.g. H 2 SO 4  or HCl) in a quantity corresponding to at least a half mol number of ferrous ions, to oxidize the ferrous iron to ferric iron, mixing the oxidized aqueous solution with a further quantity of the unoxidized ferrous salt starting solution to provide a mol ratio of ferrous salts to ferric salts of 1: 4-2: 3 respectively, neutralizing the mixed aqueous solution with ammonia gas to give a slurry containing ferroso-ferric oxide and an ammonium salt (e.g. sulphate or chloride) and then separating ferroso-ferric oxide from the ammonium salt solution by filtering the neutralized slurry and crystallizing from the filtrate. The nitrogen dioxide gas, preferably present in a mol ratio of at least <SP>1</SP>/ 30 th the amount of ferrous iron, may be manufactured from ammonia and air using a platinum or platinum-rhodium catalyst or by reacting sodium nitrite with sulphuric acid. Excess N0 2  from the oxidizing step together with nitrogen, unreacted oxygen and moisture from the oxidizing step may be absorbed into the aqueous solution before entering the oxidizer. The pH of the slurry is preferably adjusted to more than 7.0 in the neutralization step which may average more than two hours. Ammonia and steam produced in the neutralization step may be absorbed into the mixed solution before it enters the neutralizer. The slurry may be agitated for more than 30 minutes after neutralization.

Title: Arrangement for controlling ignition systems for internal combustion engines
IPC: F02P5/15
Filed: 1973-11-06
Abstract: 1409358 Ignition systems; timing ignition BROWN BOVERI & CIE AG 6 Nov 1973 [10 Nov 1972] 51385/73 Heading F1B An arrangement for controlling an ignition system comprises a rotary member which in use rotates synchronously with the crank-shaft of the internal-combustion engine on which the arrangement is used, marking means a b on the rotary member, sensing means 3 for sensing the marking means as the rotary member rotates, the sensing means being operable to produce signals the intervals between which are dependent on the speed of rotation and the arrangement of the marking means on the rotary member and a discriminator (AND-gate 4) connected to the output of the sensing means and operable in response to the signals to produce an output signal for initiating the storage of ignition energy, the discriminator being arranged in such a manner that the time of occurrence of the output signal varies with the speed of rotation of the rotary member in such a way that the interval between the output signal and the moment of ignition corresponds to the time required for the storage of ignition energy. A reference point 1 is arranged on the rotary member and another sensing means 6 is operable in response to the passage of the reference point to trigger delivery of the stored ignition energy. As shown the rotary member is in the form of a disc and the marking means are in the form of lines at the edge of the disc, the spacing between the lines progressively increasing in the direction in which the disc is rotated. Alternatively the marking means may be magnetic or in the form of an alternating waveform. If the engine is rotating at a slower speed than 6000 revolutions per minute the time interval between signals from the sensor 3 resulting from the first and second markings of a group of markings is of such a magnitude that the time delayed sensor signal produced by the first marking has already vanished at the relevant input of the AND-gate 4 before the undelayed sensor signal produced by the second marking appears at the other input. Therefore no signal is produced at the output of the AND-gate 4. If the crankshaft is rotating at 6000 revolutions per minute, when the second marking a passes the sensor 3 the sensor signal produced thereby is applied without delay to the first input of the AND-gate 4. At the other input of the AND-gate there is applied a time delayed signal of the first marking a so that there is a condition of coincidence at the AND-gate 4 which thus produces an output signal which causes the ignition coil energization to be initiated. If the ignition coil forms part of a blocking oscillator the output of the AND-gate 4 is used to trigger the blocking oscillator. In a modification (not shown), a further sensor is associated with the disc at the 270 degrees position and a time delay stage 5 is omitted. The ignition timing can be raised according to the engine speed.

Title: Ink drop printing systems

Filed: 1973-11-07
Abstract: 1434577 Automatic control of sonic velocity AB DICK CO 7 Nov 1973 [6 Dec 1972] 51710/73 Heading G3R In order to keep constant the speed of sound in an ink which is for use in an ink drop printing system having a nozzle which operates in a fluid resonance condition, the speed of sound in the ink is measured and if it differs from a pre-set value, a characteristic of the ink such as its viscosity is adjusted to restore the speed of sound to the set value. As shown the ink is contained in a reservoir 14 wherein are spaced sonic transmit and receive transducers 25, 28. A train of square pulses is fed from a clock source 20 to a driver 22, producing sonic pulses in the ink, and via an inverter 26 to an AND gate 30. The output pulses from the receiver transducer 28 are also fed to the gate 30 and as long as these arrive after the end of the corresponding clockpulse, the gate remains closed. When a pulse from the transducer 28 arrives during the clockpulse, gate 30 is opened and a circuit 32 opens a valve 12 for 150 micro-seconds, to add a fixed amount of solvent from a tank 10 to the ink. A delay circuit 34 prevents the addition of more solvent during a mixing period. The speed of sound in the ink may alternatively be kept constant by altering the ink temperature.
