Title: Rapid carbon determination

Filed: 1964-12-14
Abstract: 1, 043, 057. Determination of carbon. LABORATORY EQUIPMENT CORPORATION. Dec. 14, 1964 [Jan. 9, 1964], No. 50758/64. Heading B1X. [Also in Division G1] Carbon in an oxidizable material is determined by burning a sample of the material in oxygen, transporting the gaseous products of combustion mixed with excess oxygen through a purifying train for removing from the mixture components other than carbon oxides and oxygen and for converting carbon monoxide to carbon dioxide, and therefrom into the lower end of an analyses chamber beneath a vertically displaceable wall to raise the wall off the bottom of the chamber, collecting a predetermined volume of the carbon dioxide/ oxygen mixture below the raised wall at predetermined pressure and temperature and determining the carbon dioxide content of that volume of the mixture. The apparatus comprises a vertical tubular analysis chamber having therein a close fitting freely movable piston adapted to float on a column of gas within the chamber, an inlet to the chamber below the lowest position of the piston, a combustion chamber having an entry for the supply of oxygen thereto and an outlet for the products of combustion, between the outlets from the combustion chamber and the entry to the analysis chamber a purifying train, means for determining when the piston has risen to a predetermined height and means for sensing the carbon dioxide content of the gaseous mixture below the piston at that height. In the embodiment described in relation to the drawings, the sample (which may be steel, iron or other metal, coal, oil or carbides) is burnt in induction furnace 42 in a stream of oxygen from source 12. The analysis chamber 34 is previously swept out with oxygen from the top downwards to drive aluminium piston 128 (Fig. 2 not shown) to the bottom of the chamber. When the carbon dioxide-oxygen mixture emerging from purification train 46, 48, 50 passes into the analysis chamber through a restricted orifice (to improve mixing) at its bottom end, the piston rises in the chamber until it intercepts a beam of light actuating a photo-cell which shuts off the flow of oxygen from source 12. The carbon dioxide content of the gas mixture is measured using a bridge circuit which includes thermistors 118, 120 set in block assembly 108 mounted on glass tube analysis chamber 34 over a window 82 in the chamber (Fig. 4 not shown) thermistor 118 being exposed to the inside of chamber 34 and thermistor 120 being the reference thermistor. Fig. 7 (not shown) is a diagram of the electrical circuitry used in automatic operation of the apparatus.

Adjustment is effected (Fig. 1) by a screw-threaded rod 13 and knurled wheel 13a, or (Fig. 2) by fluid under pressure supplied, through a bore 1b in the end connection 1a, from a manually or vehicle-engine operated pump, or from a container on the part 1a containing liquefied gas or solid carbon dioxide and controlled by a cock. The gas and liquid in the shock absorber are separated by a diaphragm 9 or a further floating piston 16. In Fig. 1 the space 10 is in liquid communication with the working cylinder via ports 12 and grooves 12a. If the shock absorber of Fig. 2 is used in a telescopic motor cycle fork, the suspension spring may be located outside the cylinder, or between the working piston 2 and the floating piston 16. Alternatively the gas above the floating piston may itself constitute the suspension spring.

Abstract: 1,218,510. Selective signalling. WESTERN ELECTRIC CO. Inc. 17 Oct., 1969 [18 Oct., 1968], No. 51027/69. Heading G4H. In a delta modulation system the magnitude of the increments of charge applied to the feedback integrating capacitor are proportional to the rate of change of the integrated feedback signal. This produces small increments for slowly varying input signals, large increments for rapidly varying input signals, and hence better fidelity. As described an increment of charge 46, Fig. 4, of K dv/dt is subtracted from the feedback integrating capacitor 40 every bit period, and during those bit periods that a pulse is actually transmitted a charge of 2K dv/dt is added to the capacitor, thus resulting in a net addition of K dv/dt. A small initial reference potential 48 is superimposed upon upon the rectified rate signal in order to ensure accurate starting.

Patent GB-517099-A (GB)
Abstract: 517,099. Directive wireless signalling; valve relays. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Aug. 24, 1938, No. 24950. Convention date, Aug. 28, 1937. [Class 40 (v)] [Also in Group XXXVI] The amplitudes of wireless impulses are measured or compared by measuring the slope of the rising part of the impulse curved When applied to a homing direction-finding system in which the receiver output is applied to a visual indicator through a reversing- switch operating in synchronism with the phase reversal of one of the aerial pick-ups, the amplitudes of the ground-wave impulses received during the two switch positions are so compared. This indication is independent of space-wave echoes, even for a large separation of transmitter and receiver, when the ground and space wave impulses B and R, Fig. 2, become superimposed, since the rising part of the resultant impulse P is due solely to the ground impulse and its slope is therefore a measure of the amplitude of the ground impulse. The invention is also applicable to the determination of the distance of an impulse transmitter by measuring the strength of received impulses. In Fig. 4 the slope is obtained by measuring the time t, Fig. 3, in which the impulse rises from one predetermined voltage E1 to another E2. The output from the receiver is applied to the grids of gas-filled discharge tubes 3, 13 which ignite respectively at voltages E1, E2. When the tube 3 ignites, the resulting constant voltage across resistance 5 begins to charge the condenser 9 ; this charging ceases when the tube 13 ignites, since the consequent voltage across the resistance 15 is fed back to bias the tube 13 to cut-off. The voltage developed across the condenser 9 is a measure of the time t. In Fig. 5 the slope is obtained by measuring the voltage E2 attained during a fixed time t from a predetermined lower voltage E1. The receiver output is applied to the grids of a gas-filled tube 19 and valve 31, which both become conductive at a voltage E1. The tube 19 charges a condenser 25, the voltage across which biases the gas-filled tube 27 ; the time-constant of circuit 23, 25 is such that the tube 27 ignites at a time t after the tube 19, and the consequent voltage across the resistance 29 is arranged to bias the valve 31 to cut-off. The voltage across the condenser 33 is a measure of the voltage E2 attained during the time t.
