Title: Improvements in or relating to substantially vertical shaft furnaces and the operation thereof
IPC: F27B1/02
Filed: 1959-07-06
Abstract: 896,460. Shaft furnaces. SCHMID, A., and HOFER, H. July 6, 1959 [Aug. 9, 1958], No. 23202/59. Class 51 (2). A shaft furnace for carrying out endothermic reactions, e.g. burning limestone or dolomite, has a preheating zone V, burning zone B and cooling zone K, upper and lower openings b and a respectively for the supply and discharge of air, inert gas, burnt gas and fuel, and openings (not shown) in the burning zone for introducing fuel. A blast device has a pressure line and a suction line selectively connected to openings a and b so that the furnace may be reversibly operated in alternate periods. If solid fuel is mixed with the charge it may be necessary to supply inert gas initially after a reversal to prevent premature ignition. The invention may also be applied to a duplex shaft furnace connected at the middle or at either end and reversibly operated to give partial updraught and partial downdraught. With the connection 5 in the lower half of the furnace, Fig. 2, in one phase of operations air is introduced at a, a<SP>1</SP> and b, and fuel at c in shaft 3, combustion taking place partially in shaft 3 and being completed in shaft 4. Waste gases escape at b<SP>1</SP> giving a preheating zone V. In the second phase the operations are reversed, waste gas escaping from shaft 3 at b. With connection 5 in the upper half of the furnace, Fig. 3 (not shown), combustion commences in the first shaft on updraught, some gases escaping through the top of the shaft to preheat incoming material and combustion is completed in the second shaft with downdraught. With the connection 13 in the middle, Fig. 4, in one phase gas introduced at b and air at a or vice versa mix in said connection and burn in shaft 12 while escaping upwardly and downwardly. Alternatively, air can be introduced at a and b and fuel at c and d. Again the furnace operation is reversed.

Title: Apparatus for the electrical measurement of torque
Filed: 1959-07-09
Abstract: 929,231. Electric measuring systems. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. July 9, 1959 [July 12, 1958], No. 23584/59. Class 40 (1). Apparatus for producing an electrical output signal significant of a torque applied to an inertiapossessing movable member having its motion through an angle from a datum position opposed by both a damping torque dependent on the angular velocity and a restoring torque dependent on the angular movement includes electrical circuitry responsive to angular motion of the member to produce three electrical signal components proportional respectively to angular acceleration, angular velocity and angular movement and a summating circuit in which the three components are added to one another to give an electrical output signal significant of the applied torque. In the construction shown in the drawing a shaft 1 has connected to one end a vane 2 which is subjected to a torque by flow of a medium, such as air, therepast. A restoring torque tending to hold the shaft in a central datum position is applied to it by two springs 3, 3<SP>1</SP>. A potentiometer device 4 having a pair of ganged wipers rotated by movement of the shaft 1 produces a voltage U 1  across a resistor 9 proportional to the angular rotation of the shaft 1. A coil 5 is provided on the shaft and moves between two magnet poles 6, 6<SP>1</SP> so that there is induced in the coil 5 a voltage U 2  proportional to the angular velocity of the shaft. The voltage U 2  is impressed through an amplifier 7 across the primary winding 8<SP>1</SP> of a transformer 8. The secondary voltage U 3  of the transformer 8 is proportional to the rate of change of the voltage U 2  and is proportional to the angular acceleration of the shaft 1. The three voltages U 1 , U 2  and U 3  are applied by switching-in adjustable resistances 9, 10, 11 connected in series to give a summation voltage tapped for measurement purposes across the terminals 12, 12<SP>1</SP>. The resistances 13, 14, 15 are adjusted so that the summation voltage across the terminals 12, 12<SP>1</SP> represents the sum of the integers in the equation of motion which are equivalent electrically to the voltages U 1 , U 2  and U 3  respectively. An inductive braking system is provided by a coil 17 on the shaft 1 between the magnet poles 16, 16<SP>1</SP> and is connected to the output side of the amplifier 7. An amplified voltage proportional to U 2  produces a damping torque on the shaft 1 in opposition to the torque arising from the flow of air on the vane 2. An adjustable time delay circuit comprising an RC system 18, 18<SP>1</SP> can be connected between the amplifier 7 and the coil 17 to retard the coming into operation of the damping torque produced by the coil 17.
