Patent GB-1267132-A (GB)
IPC: C06C5/08
Filed: 1970-05-01
Abstract: 1,267,132. Fusecords. DYNAMIT NOBEL A.G. 1 May, 1970 [2 May, 1969], No. 21141/70. Heading F3A. A process for the production of fusecord comprises supplying particulate explosive from a hopper in the form of a column around which a sheathing is continuously produced, the supply of explosive from the hopper being enhanced by causing one or more threads of textile material to pass through the hopper along a line which is at an angle to the vertical, the position of which line within the hopper is being constantly changed so that the explosive material in the hopper is continuously cut by the thread, the thread then being continuously introduced into the sheathing together with the explosive material. The thread describes a circular or penduline path and is vibrated as it enters the hopper. The surface of the thread is roughened. An apparatus for the process comprises a hopper 2. Fig. 1, a reel 10 from which the thread 4 is pulled, a rotating disc 5 for causing the thread to describe a circular path, and a spinning machine in whose plane 7 a strip 3 of paper or plastics is wrapped around the explosive column 8. In another apparatus, Fig. 2, discs 5 cause the threads 4 to rotate upon withdrawal from reels 10, whilst a holder 6 rotates the reels. In another embodiment (not shown) the thread is given a rotary movement as it is withdrawn from a reel and passed over the edge of a rotating or a non-rotating, vertically reciprocating disc. Another way in which the thread can be given a circulatory movement is by means of a cam gear. The explosive used in the fusecord is Hexogen or nitropenta and is present in an amount of less than 1 g./m. or up to 100 g./m. 80% of the explosive has a grain size less than 0À1 mm. Fibres are wound around the sheathed column of explosive.

Abstract: 1289484 Electric motors; converting; control of AC motors TOKYO SHIBAUR A ELECTRIC CO Ltd 16 Dec 1969 [20 Dec 1968 24 Feb 1969] 61294/69 Headings H2A H2F and H2J A brushless D.C. motor system includes a polyphase stator winding supplied from a thyristor inverter and a rotor position sensor which controls a device for effecting forced commutation of the inverter thyristors. In the system shown, a motor 16 has a permanent magnet rotor 18 and a three phase stator winding 17 energized through an inverter 10 and rectifier 11 from an A.C. supply, variation of the firing angles of the rectifier thyristors permitting speed control of the motor. The motor includes two rotor position sensors 19, 20, of which the former directly controls the inverter thyristors S1-S6 and the latter controls a forced commutation device 23, 24. 24 comprises a diode bridge rectifier fed from the inverter output and 23 includes a capacitor 26 normally charged to the value of the D.C. input to the inverter. Assuming S1 and S5 to be conducting to pass current through windings U and V, at the time of commutation from S5 to S6 the sensor 20 triggers an auxiliary thyristor 32 to discharge capacitor 26 through an inductance 33. When the voltage across the capacitance is reversed a second auxiliary thyristor 25 is turned on to complete a path through the capacitor 26, diode 29, thyristor S5, diode D2 and thyristor 25. The current in S5 is reduced to zero, the thyristor is reverse biased and thyristor S6 is turned on to complete the commutation. At the time of the next commutation from S1 to S2, the thyristor S32 is used in conjunction with a third auxiliary thyristor 27 to form a current path through S1 to turn this thyristor off. An auxiliary voltage source 30 ensures the minimum voltage across capacitor 26 necessary to ensure forced commutation in the event of low rectifier 11 output voltages corresponding to low speeds of the motor. In a modification, Fig. 3 (not shown), in which natural commutation of the inverter thyristors occurs at low motor loads, only one rotor position sensor (19) is employed, and this sensor triggers both the inverter thyristors and, through a delay circuit (39) and an AND gate (40), the forced commutation device. The other input of the AND gate comes from a comparator circuit (41) which gives an output only when the D.C. current to the inverter is above a predetermined reference value, so that forced commutation only occurs under heavy load conditions and at starting. The rotor in Fig. 3 is of the inductor type, comprising two magneticm aterial cups with intermeshing teeth, disposed in the field of a stationary exciting coil (38).
