Title: Method of manufacutring branched pipe fittings
IPC: B21K1/14
Filed: 1973-06-20
Abstract: 1421266 Making pipe fittings; stamping TSENTRALNY NAUCHNO - ISSLEDOVATELSKY INSTITUT TEKHNOLOGII MASHINOSTROENIA 20 June 1973 29262/73 Headings B3A and B3Q A method of making branched pipe fittings from tubular metal stock 1 comprises compressing the stock radially in a first pair of dies 2, 4, having substantially semi-cylindrical complementary recesses 3, 5, one of which has an opening 6 permitting the formation of an offset (7), Fig. 4 (not shown), of circular cross-section in the stock at a branch outlet location, upsetting the shaped stock axially in a second pair of dies 8, 9, and compressing the upset stock 1b radially in a third pair of dies 10, 12, each of which has longitudinally and transversely extending semi-cylindrical recesses 11, 13 and 14, 15, the recesses 14, 15 serving to shape the branch of the pipe fitting. The end of the offset, which is in the form of a bulge, is cut off to form an outlet. The stock 1 is preferably a seamless metal tube. In an alternative embodiment the offset is in the form of a branch (7c), Fig. 9 (not shown), and a rod (18) and die (16) are passed through an aperture (17) in the stock to shape the offset. When the dies 2, 4 are closed the die (16) is pulled through the aperture (17) to form the branch (7c) in the opening 6. In the subsequent forming steps the branch is flattened in cross-section when the dies 8, 9 upset the formed stock, Fig. 13 (not shown), and it is restored to circular cross-section by the dies 10, 12. By this method it is possible to form longer branches than when a bulge is formed in the stock.

Title: Improvements in and relating to method and apparatus for the wet spinning of artificial threads or the like
IPC: D01D10/04
Filed: 1951-12-20
Abstract: <PICT:0719718/IV (a)/1> In the wet-spinning of artificial thread, the freshly formed thread is passed over a series of storing and advancing reels in an ascending path vertically inclined towards an operator facing the free ends of the reels, the thread being completely processed during the period between its formation and its final discharge from the last of the reels; the completely processed thread is then passed overhead within reach of an operator standing on the floor of the working space to a collecting means horizontally spaced from and facing the free ends of the storing and advancing reels.  As shown, a spinning machine comprises two diverging banks of reels 10, 11 in back-to-back relation.  Each bank includes a number of thread storing and advancing reels 20-23 for each thread arranged in inclined vertical planes above a longitudinally extending coagulating bath 14.  In each vertical series the reels 20-23 are disposed with the free end of each reel extending beyond the free end of the reel beneath it to form an ascending thread path inclined towards an operator facing the free ends of the reels.  Viscose is extruded through spinnerets 15 to form artificial threads 16 in the coagulating bath 14.  The threads 16 are withdrawn from the bath by thread storing and advancing reels 20 disposed above the bath 14 and passed in succession to the reels 21 and 22 and finally to the drying reels 23.  During their passage over reels 20-22, they are subjected to various liquid treatments by the liquid distributers 17-19.  Upon leaving the drying reel 23 the thread is led by means of guides 25-27 to a thread-collecting means such as a cap-spinning apparatus 28 horizontally spaced from the bank of reels at about the level of the lowermost row of reels.  The thread-collecting means 28 collects the threads from the bank of reels 10 and similar thread-collecting means 74 collects the thread from a bank of reels 50 of a second spinning machine similar to the first.  The banks of reels 10, 11 and 50 are identical and with their coagulating baths are each about 6 feet high and accessible to an operator standing on the floor of the working area 35.

Patent GB-1103789-A (GB)
Title: Narrow frequency range, wide speed range a.c. generator
IPC: H02P9/42
Filed: 1966-07-04
Abstract: 1,103,789. Frequency changers; induction generators; alternators. BENDIX CORPORATION. 4 July, 1966 [4 Aug., 1965], No. 29965/66. Heading H2A. In a system for maintaining the frequency of an output generator within a narrow frequency range over a wide range of input speeds from, e.g., an aircraft engine, comprising an input generator for supplying a plurality of different frequencies for a corresponding plurality of predetermined speed ranges, and speed-responsive switch means, the input and output generators are mounted for rotation together, and the switch means is responsive to the predetermined speed ranges for selectively energizing the field winding of the output generator from the field winding of the input generator via the output of the input generator with a frequency corresponding to the speed range. As shown, the input or frequency supply generator 3 has, on its stator 4, field windings 6 and 8 and an armature winding 7, and has, on its rotor 5, armature windings 9 and 11 and a field winding 10. The speedresponsive switch 30 is adapted to connect armature winding 7 directly to field winding 8 with a first phase sequence in the first speed range, to connect winding 7 through rectifiers 31 to winding 8 (at this time arranged as a D.C. winding) in the second speed range, and to connect winding 7 directly to winding 8 but with reversed phase sequence in the third speed range. Where winding 7 is two-pole and winding 8 is physically four-pole, and where in the first speed range the windings are connected so that the field due to winding 8 rotates in the direction opposite to that of the rotor, the output frequency from winding 11 is equivalent to six-pole; where the windings are connected so that winding 8 produces a D.C. field, the output frequency from winding 11 is equivalent to four-pole; and where they are connected so that the field rotates in the same direction as the rotor, the output frequency is equivalent to two-pole. The field winding 15 of output generator 1 is connected to armature winding 11 and rotates with it on the same shaft. Thus, output winding 14 on the stator of generator 1, connected to load by conductors 37 to 39, produces a frequency always within a narrow range, whatever the rotor speed. Initial excitation of frequency supply generator 3 is provided by an exciter 2 having its permanent magnet rotor 16 mounted on the same shaft as the remaining rotors. The frequency generated by the output winding 17 of the exciter is proportional to rotor speed and is sensed by switch 30.

[Class 40 (iii).] A copying-telegraph receiver is driven at a speed variable in accordance with the load imposed through an oscillator 44, the frequency of which is varied in accordance with the position of the receiver relative to the receipt of framing impulses. The synchronizing impulses are produced at the transmitter, Fig. 1 (not shown), by a dark band after each line scanned, and, at the receiver, are amplified by a valve 53 to pass a current through resistances 55, 57 varying with the phase of the conducting- segment 33 on a commutator 32 attached to receiving-apparatus of the type described in Specification 308,695, [Class 40 (iii), Telegraphs, Electric]. The charge thus applied to a condenser 56 controls the current through a valve 58 and anode resistance 60, which modifies the voltage applied to an oscillator 44 and hence its frequency. The oscillations are applied through transformers 45, 41 to the grids of valves 39, 40, the plates of which are energized by an alternator 37 coupled to the driving-motor 27. The load on the motor is thus varied and its speed controlled in accordance with the relative frequency of the oscillator 44 and the alternator 37.
