Patent GB-283522-A (GB)
Title: Improvements relating to furnaces
IPC: F23N1/08
Filed: 1928-01-03
Abstract: 283,522. Gordon & Co., Ltd., J., (Assignees of Peebles, T. A.). Jan. 12, 1927, [Convention date]. Regulating combustion. - In furnaces heated by gaseous fuel from a fluctuating source of supply such as blast furnaces and where an auxiliary source of pulverized or other fuel supply is employed to make up for any deficiency of gaseous fuel, means are provided whereby the auxiliary fuel-feeding mechanism is controlled automatically by the pressure in the furnace. In cases where the gas is supplied from a common main to a battery of furnaces, one or more furnaces are shut down or brought into operation successively as the gas supply varies. Fig. 1 shows the invention applied to a boiler furnace. Blast furnace gas and air are supplied to the burner 7 from the main 8 and fan 10 respectively, the gas supply being controlled by a valve 12 actuated by the pressure in the main 8 through the regulator 13 and the air supply being controlled by a valve 15 actuated by the differential pressure existing between the gas and air supply transmitted through the pipes 17 and regulator 16. A reduction of the gas supply causes a closing of the gas and air supply valves and a diminution of steam pressure which through the pipe 60 causes the movable frame of the master regulator 40 to be lowered and through the cable 41 to operate a switch 42 controlling the motor of the pulverizer 45 so as to supply fuel to the burner 55. In the event of the gas supply being increased, the pressure in the furnace combustion chamber rises and is communicated through a pipe 20<1> to a regulator 20 which moves upwardly and through the rod 22 actuates the counterweighted damper 19, the operating lever 23 of which is connected to the rod 22 by a pin-andslot connection to allow continued upward movement of the regulator 20 after the damper has been fully opened. The continued upward movement of the regulator 20 actuates through a cable 29 a lever 30 connected to a, link 32 engaging by pin-and-slot connection with a lever 35. The latter actuates through cables 47, 51 the valve arms 48, 52 so as to regulate the associated valves to reduce the supply of fuel and air to the burner 55. Should the gas supply be sufficient to shut off the supply of auxiliary fuel the steam pressure will be sufficient to operate the master regulator 40 and cause the operation of the switch 42 to shut down the pulverizer motor. Where a battery of boiler furnaces are supplied from the main 8, the automatically operated gas valves 12 cut out or put into operation one or more furnaces in succession.

Title: Improvements in or relating to beam deflecting circuits for cathode-ray tubes
IPC: F16B13/12
Filed: 1942-01-09
Abstract: 554,172. Valve generating circuits. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Jan. 9, 1942, No. 376. [Class 40 (v)] In a valve circuit for supplying current to the deflecting-coils of a cathode-ray tube, the anode circuit is branched so that only a small adjustable fraction of the direct supply current passes through the coils, the branches being so proportioned that the deflection current is not distorted. Saw-tooth voltage is fed to the control grid 3 of the valve, and the resulting sawtooth current in the anode circuit divides between the branch comprising an adjustable resistance 6, the deflecting-coils 7, and a large condenser 8, and a second higher-impedance branch comprising resistance 9, choke coil 10, and condenser 11 across the HT supply. Distortion is avoided by making the ratio of inductance to resistance the same for both branches. A variable resistance 14 always high compared with the resistances 6, 9 is connected between HT+ and the junction 12 of the coils 7 and condenser 8, which junction is connected to the screen grid 13 of the valve. By suitable adjustment of the resistance 14 the screen-grid can be given the same voltage as the mean anode voltage, and no direct current then passes through the coils 7. Adjustment of the resistance 15 on either side of this value controls the direction and the amount of direct current in the coils, and permits correct positioning of the spot on the screen of the cathode-ray tube.

In a method of adjusting the chrominance demodulation circuit (synchronous detectors 14, 15, phase-shifter 16 and reference carrier generator 13) of a colour television receiver a signal having a frequency differing from the chrominance sub-carrier by an integral multiple of the line-scanning frequency is supplied from a generator 19 to the input of the band-pass amplifier 10 (which normally selects the modulated chrominance sub-carrier in the output of the detector 3) the outputs of the synchronous detectors (consisting of frequencies equal to the integral multiple of the line-scanning frequency) being supplied to the vertical deflection plates of individual oscilloscopes 22, 23, the horizontal scanning of which is synchronized with that of the receiver and the intensity controlling electrodes of which are supplied with pulses at the horizontal scanning frequency. The latter produce bright portions 31, 32, the positions of which give a rough indication of the relative phases of the reference wave from generator 13 with respect to the phase of the " burst. " signal in the output of band-pass amplifier 10 and enable the phase of generator to be correctly set. A circuit of the elements within block 9 is described with reference to Fig. 3 (not shown).

Title: Improvements in or relating to deflection circuits for cathode ray tube apparatus
IPC: H03K4/90
Filed: 1949-01-07
Abstract: 660,032. Saw-tooth generating circuits. PHILCO CORPORATION. Jan. 7, 1949 [Feb. 11, 1948], No. 499/49. Class 40 (vi). A saw-tooth deflection flux for a cathode-ray tube is linearized by providing a compensating inductive circuit which produces a linearizing flux. The E.M.F. induced in coils 12 (Fig. 1) by the current in the scanning coils 11 during the flyback produces a current through the compensating circuit 12, 14, 15 during the first part of the forward stroke in such a sense that the resulting flux in coils 12 opposes that due to the current in the scanning coils and so reduces the excessive steepness in the first part of the forward stroke. The L/R time constant of the compensating circuit is preferably short compared with that of the main circuit and the scanning period. In practice the value may be adjusted by varying inductor 14 and resistor 15 until the desired linearity of waveform is obtained. The coefficient of coupling of the two circuits should be of the same order as the reciprocal of the ratio of their time constants. In an alternative circuit (Fig. 2) the inductive compensating circuit is directly connected to the scanning coils.

Abstract: 848,300. Synchronous machines. WESTING- HOUSE ELECTRIC CORPORATION. Jan. 8, 1959 [Jan. 10, 1958], No. 732/59. Class 35. In a synchronous machine in which the rotor field winding 4 is energized by an auxiliary generating winding 7 and rectifiers 10 rotating with the machine shaft to avoid the use of the usual field-current slip-rings, the magnitude of the field excitation is measured by measuring the voltage induced in a stationary auxiliary armature winding 18 by an auxiliary rotating field structure 15 excited in dependence on the main field current. This auxiliary field structure may be overhung at either end of or made integral with the machine rotor 5, or. it may fit over the machine-shaft. Time-constant resistors 17 are included. The fixed exciting winding 8 of the auxiliary generator is fed with.D.C. current controlled by a regulator 12 in dependence on the. output current in the stator winding 2 of the main machine by means of current transformers 13 and rectifiers 14. The voltage induced in the auxiliary armature winding 18 may be measured directly or, as shown, after rectification, by a voltmeter 20. This voltage is also fed to the voltage regulator through a transformer 21 to provide transient damping. The auxiliary field windings 22 may be connected in series or in parallel with the field winding 4, as shown.

Abstract: 707,815. Toggle presses. PARSONS, A. T. April 4, 1952 [Jan. 10, 1951], No. 734/51. Class 87 (2) In a power press in which a reciprocating press head is connected by toggle links to a fixed part of the press and to a valve-controlled fluidoperated piston and cylinder disposed at rightangles to the toggle links and adapted to extend and contract them, the piston rod 8 of the operating cylinder is associated with the press frame (at 6) and press head 1 by a set of short toggle links 7, 13 and the operating cylinder 10 is associated with the press frame and press head by a set of longer toggle links 9, 14. The front end of the cylinder 10 is thus suspended by the links 9, 14; its rear end is suspended by links 17 from a pin 19 which is engaged in arcuate slots 20 in the side plates 4 of the frame and held in position by nut carrying a handle 22. To adjust the working stroke the height of the upper toggle links axis pin is altered by screws 25, 26 passing through a cross-bar 6 of the frame, 'the pin 19 then being altered to the same level by moving it in the slots 20 with the nut slacked off. As the piston rod 8 is forced by fluid pressure out of the cylinder 10, i.e. to the left as in Fig. 3, the toggle links 7, 13 first straighten and thus give a second stamp (the first having been given when the Piston rod moved into the cylinder) and then, after passing through dead-centre, raise the press head 1. At the same time the cylinder 10 moves in the opposite direction to the piston and thus collapses the toggle links 9, 14 (which can never straighten although the links 7, 13 can), thereby assisting in raising the press head, which is guided by rods 2 running in bearings in the side plates 4. The valve gear 28, which may be in any convenient position, controlling the inlet and exhaust of fluid to and from the operating cylinder, may be interlocked with the press guard so that operation of the press depends on the position of the guard. Instead of suspending the rear end of the cylinder 10 by links 17 it' may be supported by long links associated with the upper and lower toggle link axis pins.
