IPC: H03K3/53
Filed: 1954-09-07
Abstract: 773,224. Pulse generator circuits. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Sept. 5, 1955 [Sept. 7, 1954], No. 25932/54. Class 40(6) The Figure shows a high voltage pulse generator in which a D.C. voltage across a capacitor Cl is applied via switches S1...S4, which are preferably discharge tubes such as ignitrons or thyratrons, to charge pulse-forming networks DL1. DL2 which are subsequently discharged through a load RL. The connections to the switches are such that when the contacts are in their left-hand position, Fig. 2 (not shown), a voltage wave' will travel along network DL1 to its output terminals connected to the load RL. With the switches in the right-hand position, Fig. 3 (not shown), the applied voltage will travel along network DL2 to load RL but the polarity of the pulses generated in the load RL will be the same in both switch positions. Since the networks DL1, 2 are charged oppositely during alternate pulses the voltage produced across load RL will be twice the supply voltage.

Abstract: 205,825. Blass, S. Oct. 22, 1923. Planting-machines.-In a plant-setting machine comprising funnels for receiving the plants, carrying them round, and discharging them into holes or furrows, the plants are inserted into the funnels root first, and the funnels remain vertical during the operation and do not enter the ground, but are held stationary relatively to the ground as the plants are deposited, the wheels of the machine being arranged so as to compress the soil about the roots of the plants. The wheels are of different diameters and are displaced relatively to one another. They are also inclined so as to be near one another at the bottom. The funnels t are carried by axles o mounted in spokes l on an axle d which is driven from one of the wheels through bevel and spur gearing. When near the ground the funnels move backward at the same speed as the machine moves forward. They are controlled by the engagement of rollers e, f with guides k' - - k'. The lines y, s indicate the inclination of the funnels at different parts of their paths. In the upper part of the path the tops of the funnels move only slightly with regard to the machine, so as to facilitate insertion of the plants by the attendant. The funnels are normally closed at their lower ends by hinged plates j which are swung back as the funnels approach the ground by the engagement of lever arms g with stops h. The plants then drop down and the soil is pressed against their roots while their upper parts are still in the funnels.

Title: Process and apparatus for forming fibres
IPC: C03B37/06
Filed: 1956-08-30
Abstract: 793,913. Glass manufacture. OWENSCORNING FIBERGLAS CORPORATION. Aug. 30, 1956 [Sept. 9, 1955], No. 26581/56. Class 56. In the production of glass or like fibres by subjecting molten streams to a high velocity blast, the streams are positively produced under pressure, which may be gas pressure above the level of the glass in the melting furnace, or may be pressure produced mechanically in the passages to the glass discharge nozzles. In Fig. 1, the melting chamber 10 is charged with glass marbles by a gas-tight worm 24, and is heated by burners 28. The pressure of the combustion products may be used to assist in ejecting the glass through nozzles 46 of refractory metal, or other pressure gases:may be admitted through the tube 30. The vent valve 36 is manually or automatically regulated for adjusting the pressure above the glass. The viscosity of the exuding glass may be regulated by electrical heating in the feeder 44 carrying the nozzles 46. The glass streams are blasted downwardly by combustion products from a burner 55 having a slit-like nozzle 60, the attenuated fibres being sprayed with a binder at 80 and collected on a conveyer 70 having a suction box 74 and consolidating rollers 77. An induced current of cold air passes downwardly through the channel 43 and may be regulated by an adjustable baffle 45. This cold air increases the viscosity of the glass streams to form nubs from which the hot blast draws the fibres. The nozzles 46 may be in the end wall of a forehearth at the same level as the melting zones of the furnace. In a modification, glass streams are presented by opposed nozzles to each side of the ribbon-like blast, each set of nozzles being separately supplied from the melting furnace. Each set of glass streams are cooled to form nubs by cold air currents induced as in the Fig. 1 construction. The opposed nozzles may be in alignment, or may be staggered. In a further modification, Fig. 6, the pressurized melting tank 112 feeds an annular forehearth 124 from which projects an outwardly directed ring of nozzles 130. An annular burner arrangement, i.e., either one annulus fed with a combustible mixture by a number of pipes 145 and having a continuous ring-slit for the discharge of the blast, or a number of burner sections, separately fed, assembled into an annulus, blasts the glass streams downwardly on to a collecting conveyer. The nubs are formed by induced cold air currents controlled by an annular damper 148. In another modification, the pressure is applied by rotating screw feeders in a cylindrical passage leading from the melting furnace to the nozzles which are inwardly directed from a ring-shaped forehearth. The blast nozzle is circular and concentric with the glass-forming nozzles.

IPC: H02P23/00
Filed: 1960-08-02
Abstract: 913,668. Automatic speed-control systems. UNITED AIRCRAFT CORPORATION. Aug. 2, 1960, No. 26751/60. Class 38 (4). In an automatic control system wherein a datum signal proportional to the desired speed of a rotating element is produced by a selecting device and compared with a signal proportional to the actual speed of the element to derive an error signal, the selecting device is controlled to prevent rapid changes in the datum signal from producing rapid changes in the error signal. As shown, the output of an engine-driven tacho-generator 10 is rectified and applied to a potentiometer 22, 20 to derive a voltage at a tapping 24 which is proportional to engine speed. A transformer 32 is connected to lines 14, 16 and the secondary voltage is applied across a resistor 36 and capacitor 38 selected so that the voltage across the capacitor is independent of change in engine speed. The voltage across capacitor 38 is rectified and applied to a potentiometer 42 and the voltage at an arm 44 is set to a datum value representative of a desired engine speed. A control winding 28 of a magnetic modulator is energized by the difference between the datum voltage and the engine-speed voltage. A capacitor 52 is connected across the tapped portion of the potentiometer 42 to slow down any change in the voltage applied to winding 28 due to movement of the arm 44. A switcharm 46 is moved to engage a contact 48 to shunt the winding 28 by a resistor 47 for stand-by operation. When the arm is returned to engage a contact 45 for normal operation, the voltage across capacitor 52 slowly changes to the voltage of arm 44 so preventing the application of a large difference voltage to the control winding 28. In an arrangement for controlling the fuel supply to a gas turbine, Fig. 3 (not shown), the magnetic modulator controls through an amplifier a two-phase motor actuating a fuel supply valve.

Title: Improvements in apparatus for washing coal
IPC: B03B5/62
Filed: 1931-09-25
Abstract: 385,372. Washing granular materials. BLATCH, F. H., 228, North Laurel Street, Hazleton, Pennsylvania, U.S.A. Sept. 25, 1931, No. 26820. [Class 82 (ii).] In coal-washing apparatus in which a downwardly flowing stream of coal meets an upward current of water means are provided so that the resistance offered by the coal to the upward flow of water automatically controls the supply of coal. Water from a nozzle 15 flows through a substantially U-shaped conduit 3 and in its upward flow meets a flow of coal down a branch 6, the lighter constituents being carried up a passage 5 and over a wall 30 into a compartment 32 closed by a wall 31 having adjustable doors 34 at each side through which they are discharged into perforated troughs 35. The heavier constituents sink through the water stream and discharge through a port 20, which may be provided with an adjustable lip 80, Fig. 4, into a pocket 22 in which works a conveyer 23. The compartment containing the conveyer and of which the pocket 22 forms a part extends centrally of the apparatus so that the conveyer rises between the troughs 35. This compartment contains a float 70 pivotally connected to one end of a lever 58 carrying a weight 65 and adjustably pivoted at 60 and which is connected at its other end to arms 57. The arms 57 carry a shaft 51 on which is a rotary bladed member 53 which controls the supply of coal from a hopper 50 to the branch 6, the member 53 being driven by a sprocket chain from the shaft driving the conveyer 23. When the resistance of the coal to the upward flow of water in the conduit 3 increases, more water flows through the port 20, the float rises, and the shaft 51 and the bladed member 53 are lowered, restricting the supply of coal. In a modification, Fig. 4, a sliding gate 87 controls the supply of coal from a hopper 85, the gate 87 being connected to the end of a pivoted lever 89 by a pin-and-slot connection. The point at which the descending coal enters the upflowing water stream may be varied by raising or lowering a partition 11.
