Title: Improvements in or relating to apparatus for calibrating a time-delay circuit
IPC: H03K5/14
Filed: 1956-07-25
Abstract: 845,876. Measuring time delay. HAZELTINE CORPORATION. July 25,1956 [Aug. 12, 1955], No. 23038/56. Class 37. Calibration of a time delay circuit 10, Fig. 1 is effected by feeding a pulse from generator 14 simultaneously to the circuit 10 and a blocking oscillator 15 which thereupon produces a series of timing pulses which are compared with the pulse output from the time delay circuit 10 in a coincidence circuit 17. As shown Fig. 2 the output A from the generator causes the blocking oscillator 15 to produce timing pulses B whose spacing is determined by the return time of pulses produced in the coaxial line 16. The position of the output pulse C, from the time delay circuit (reshaped if necessary by a blocking oscillator 19) is adjusted by the control 11 until coincidence with one of the pulses B is detected by the meter 18. The setting of the control I is thus accurately correlated with a known time interval. The output from the delay circuit 10 is also caused to operate a blanking circuit 20 to produce a pulse D which shuts down the blocking oscillator 15 prior to reoperation by the next pulse from the generator 14.

Title: Improvements in or relating to the winding of cops with reserve coils
IPC: B65H67/06
Filed: 1958-07-23
Abstract: 900,191. Winding reserve coils. REINERS, W. July 23, 1958 [Aug. 1, 1957], No. 23680/58. Addition to 874,844. Classes 120 (2) and 120 (3). The method and apparatus of the parent Specification are modified for application to cops formed with the free outer end, which may include a cord, of yarn located at the base end of the cop. To this end, the step of rotating the cop to unwind the yarn is preceded by axially withdrawing the free end portion by suction directed away from the nose end of the cop without rotating the cop, while the step of drawing off a controlled length of the thread during the rotation of the cop in the unwinding direction is terminated when the thread has been unwound as far as the nose-end whereby the reserve coil then formed by rotating the cop in the original winding direction is located on the nose end. In Fig. 4, G is the starting- end of the wind, F the finishing-end, both of which are at the base-end of the cop, F being joined to the terminating-coils of the wind by a few loose turns as shown. Suction nozzles 18, 16 are provided, the suction being applied to one or the other according to the position of a flap 21 controlled by a lever 22. Nozzle 18 is pivoted; when it is in the operative position shown, flap 21 is in the full-line position and the the suction is directed to draw-off ends F and G. The position of flap 21 is now reversed, nozzle 18 pivoted to the inoperative position, and the cop rotated in the unwinding direction, Fig. 5 ; the ends F, G are severed by shears 17, while a length F1 is drawn into nozzle 16 until the thread unwinds to a point at the nose-end, whereupon the direction of rotation is reversed and the length F1 wound-up thereat being guided to the nose-end by the rear wall of nozzle 16. In Fig. 1, cops K for treatment are fed successively to a support 6 by a toothed wheel 4 and guides 5, nozzle 18 and a shear blade 17, are moved into and out of operative position by the rotation of a shaft 24. After these have done their work, the cop is moved off support 6 by a pusher 7 on to rollers 14, 15 above nozzle 16, the rollers rotating first one way and then the other. A link 28 for moving nozzle 18 and the lever 22 for moving flap 21 are controlled by a double-lever 27 fixed on a shaft 24 to which the operating-member of the shears is also secured. Pusher 7 is loosely mounted on shaft 24 and is integral with an arm 7a following a constantly rotating cam 8. Other cams rotate shaft 24 and reverse a switch controlling the rotation of rollers 14, 15.

Title: Pipe bending machines
IPC: B21D7/025
Filed: 1975-05-30
Abstract: 1474848 Bending tubes TSENTR NI INST TEKHNOLOGII MASHINOSTROENIA 30 May 1975 23721/75 Heading B3E A pipe bending machine comprises a rotary member to which one end of the pipe is attached, a displaceable member to which the other end is attached, and a connection between the members such that when the displaceable member is displaced to move the pipe axially and rotate the rotary member so that the pipe is bent, the pipe is subjected to compression between the members. Fig. 1 shows an embodiment before bending, and Fig. 5 is a part sectional view after the bend is made. A bed 1 supports a crosshead 3 on slideway 2, a carriage 7 by wheels 10 and rails 11, and bearings 31 (one shown) for a shaft 30. The crosshead 3 is displaceable by cylinders 4. The carriage 7 is movable along its rails by motor 8 and drive 9, and supports a tube abutment plate 17 on slide 18, the plate having tube grips 20 and being reciprocable by screw and nut mechanism 14, 16 driven by motor 12. Relative longitudinal movement of the crosshead 3 and carriage can be restrained by rotation of two armed member 25 so that recesses 28 in its ends engage rods 23 on the crosshead between collars 24. The bending head comprises a pipe clamp 35 and abutment plate 36 mounted on a support 34 movable radially along a forked arm 32 on shaft 30 by screw 38 and motor 39. Discs 41 (one shown cut-away) biased by weights 48 are secured to shaft 30, and are connected to crosshead 3 by chains 44 secured to portions 42 of the discs, so that the chains are radially further from the axis of shaft 30 than the tube 19. In operation the position of bearings 31, the position of support 34 radially of shaft 30, and the parts 42 of discs 40 are chosen to suit the bend required. A tube is held in grips 20, and the carriage is advanced to abut the tube against plate 36, the tube running a guide roller 6 and thrust rollers 45. Arm 25 is then engaged between collars 24, and screw 14 driven to put the tube under compression. Clamp 35 is applied, and cylinders 4 are then extended to advance the tube, rotate the bending head, and bend the tube, which remains under compression sufficient to prevent thinning of the tube wall on the outside of the bend, since chains 44 prevent the shaft 30 rotating as much as it would if free. Clamp 35 is then released, so that weights 48 fall to cause the tube to advance out of the machine. An induction heater 49 and spray cooling unit 50 are incorporated.
