Title: Improvements relating to the regulation of the supply of air to cupola furnaces
IPC: F27B1/26
Filed: 1934-03-16
Abstract: 420,642. Regulating air supply to cupola furnaces. FOXBORO CO., Foxboro, Massachusetts, U.S.A.-(Assignees of Lewis, S. R. ; 214, Grand Boulevard, Detroit, Michigan, U.S.A., Spink, L. K. ; 1, Maple Place, Foxboro, and Hagerman, B. W. ; 25, Florence Street, Worcester, both in Massachusetts, U.S.A.) March 16, 1934, No. 8341. Convention date, May 3, 1933. [Class 51 (i)] In order to ensure a constant supply of air by weight to a cupola furnace, the blast supply pipe 9 leading from the blower has a branch leading to the atmosphere provided with a valve 17 under the control of the temperature, pressure and velocity of the blast so as to permit variable amounts of blast to pass from the pipe 9 to the atmosphere. Pressure on opposite sides of a diaphragm 15 is communicated through pipes 37, 39 to diaphragms 33, 35, the differential pressure serving to actuate a slotted lever 45 and adjustable link 47 pivoted to an arm 46 pivoted at 24 and actuating by a pin 48 a flapper plate 23 controlling a fluid pressure discharge orifice 21. Fluid is supplied to the orifice 21 by a pipe containing a bellows for actuating a hollow valve 27 controlling pressure air from a pipe 28 to a chamber below a diaphragm 19 and also exhaust from the chamber to atmosphere. The diaphragm 19 is connected by a crosshead and links 193, 197 to the valve 17. A temperature sensitive element 55 in the pipe 9 contains a volatile fluid which transmits pressure through a pipe 53 to a diaphragm 51 while a diaphragm 49 is also subjected to pressure of air from the pipe 37. The diaphragms 51, 49 are connected to a common lever 61 controlled by a spring 63 and connected by a link 65 to the adjustable link 47 so that the movement of the flapper plate 23 is compensated for temperature and pressure. Specification 106,276, [Class 106 (ii)], is referred to.

Abstract: 377,696. Motors. SANGAMO ELECTRIC CO., Springfield, Illinois, U.S.A. March 20, 1931, No. 8653. Convention date, Jan. 19. [Class 35.] A synchronous motor, especially adapted for driving electric clocks, is provided with two air gaps separated by a ring of polepieces and traversed in series by the magnetic flux and an armature co-operates with each air gap. In the arrangement shown one armature consists of a permanent magnet 46 and an induction member 48. The magnet 46 co-operates with the air gap between teeth 21 on a magnetic disk 16 at one end of a coil 14 carrying an alternating current and teeth 23 on a ring 22 surrounding the disk. The poles of the magnet are preferably bifurcated, the space between the divisions being equal to the width of one of the teeth 21 and the air gaps on either side of it. The ring 22 also carries pairs of polepieces 26, 27 alternating with jaws 11, 12 on a magnetic disc 13 at the other end of the coil 14. The polepieces 11, 26 are surrounded by shading rings 32 so as to produce a rotating field with which the induction member 48 co-operates. The member 48 consists of a bell of copper or the like surrounded by a band 54 of magnetic material. Fig. 5 shows a modification consisting of a body 61 of magnetic material with teeth 64, and a bell 65 of copper or the like. The member 68 may be loose on the spindle 41 carrying the magnet 46 and be connected with the magnet by a spring arm 78 or a helical spring. In a modification the two armatures are at opposite ends of the spindle 41. The polepieces 11, 12, 26, 27 being less numerous than the teeth 21, 23, the synchronous speed of the member 48 is greater than that of the magnet 46.

Abstract: 744,354. Electric indicating systems. ARMSTRONG WHITWORTH AIRCRAFT. Ltd., Sir W. G. Feb. 23. 1953 [April 5, 1952], No. 8777/52. Class. 40(1) In a telemetering system a number of signals, of which the durations or intensities represent the values of the quantities to be telemetered; are sequentially transmitted as modulations of a carrier and are converted at the receiver into voltages or pulse positions representing the durations or intensities of the signals, these voltages or pulses being applied in sequence, together with a time base signal, to a cathoderay tube in order to produce a display; a second display providing a datum for comparison with the first is produced by the application to the cathode-ray tube of the 'output of a calibrated generator in conjunction with the time base signal, the telemetering signals and the output of the calibrated generator being fed through common circuitry and applied alternately to the cathode-ray tube so that the two displays are visible at the same time. As shown, a line 11 carries incoming telemetering signals and a synchronizing signal which is separated at 12 and triggers a generator 14 to prbduce a. sawtooth time base signal 22. This is applied to a cathoderay tube 44 and also to a differentiating circuit 20, 21 which produces narrow pulses 24 which are passed through an amplifier and buffer 25 and a dividing circuit 26 to provide two oppositely-phased signals 28, 29 of square waveform and half the original' frequency. These are arranged to gate amplifiers 16 and 36 respectively so that the' telemetering signals from line 11 and a fixed; frequency signal from a calibrated oscillator 40 are fed alternately through a common frequency discriminator and demodulator 42 to the cathode-ray tube 44, producing a histogram 46 and a datum line 47 respectively. In modifications (not' shown), the output of the calibrated oscillator 40 may be variable or a plurality of datum lines may be displayed. In a pulse system (not shown) the value of the quantity to be telemetered is represented by the duration of telemetering signal and is indicated on the cathode-ray tube 44 by the position of a pulse with respect to a time base.:In this system the calibrated oscillator 40 and the common frequency discriminator 42 are replaced by a time calibration generator and a detector respectively.

Gas is dispensed from a heat insulated liquefied gas, e.g., oxygen container 18 through a service line 60 by forcing liquefied gas up a line 66 extending from near the container bottom to a point 72 above the normal full liquid level by the pressure exerted in the gas space and thence through a vaporizing coil 64 ; the pressure in the gas space being maintained by allowing a portion of the liquefied gas at a point 90 to fall under gravity down a line 92 to below the container bottom and through a second vaporizing coil 96 which discharges up a line 98 leading to the gas space. A check valve 94 prevents back flow of vapour from coil 96.

In an integrated circuit a component is isolated by surrounding it with the channel of a fieldeffect structure which is biased to pinch-off. As shown, an N-type silicon wafer has regions of P, P+ and N+ types diffused into its surfaces to form an integrated circuit. Regions 2 and 7 form the gate of a field-effect structure of which region 6 is the source and region 8 is the drain. This gate is biased by source 10 so that the channel between regions 2 and 7 is pinched off thus isolating the area enclosed by region 7 from the rest of the wafer. The parts 7a, 7b of gate 7 define the width of a strip 9 which acts as a resistor connecting region 8 to the drain of a field-effect transistor enclosed by the circular portion of gate 7. Regions 2 and 3 form the gates of this transistor while the central N + region forms the source which is grounded. It is stated that P-type region 7 may be used in addition as a resistive element in the integrated circuit.
