Title: False twisting crimping machine
IPC: D02G1/02
Filed: 1974-07-05
Abstract: 1464128 Crimping fibres and yarns BARMAG BARMER MASCHINENFABRIK AG 5 July 1974 [5 July 1973] 29882/74 Heading D1F In a false-twist crimping machine wherein a thread passes successively through a first delivery mechanism, a heater, a (false-) twister and a second delivery mechanism, the latter is in the form of a stepped roller i.e. a single roller having two coaxial portions of different diameters, or it comprises two synchronously driven (speed) stepping rollers of different effective diameters. As the thread passes from a smaller roller (or disc or portion thereof) to a larger roller -(or disc or portion thereof), a sudden pull is applied to the crimped thread length to extend and open any untwisted portions remaining therein and thus ensure uniform crimp and bulk. The thread returns, via spacer rolls as required, to the smaller roller &c before leaving the mechanism and it may then be modified as by direct passage through a second heater and a third delivery mechanism. The driven rollers &c and mechanisms may be interconnected by transmissions which enable adjusted, perhaps infinitely variable, speed ratios therebetween. Non-rotatable, perhaps reciprocatable, thread deflecting devices interposed between smaller and larger rollers &c may contact the thread along an edge to enhance the opening action.

As shown, during a wind the bobbin-holders 44 are rotated by pinions 28 meshing an elongated pinion 32, the holders engaging conical members 30 on shafts 24. The holders are reciprocated through the turntable 10 which rests on a plate 50 secured to piston rods 46, the plate having pins 52 engaging sockets in the turntable to prevent the latter rotating. At the end of a wind, the reciprocation is halted, and the rods 46 withdrawn to lower the turntable; the plate 50 descends on to base-plate 41 and separates from the turntable which comes to rest on rollers 71 where a ring gear 19 meshes a gear 20. The turntable is thus rotated through 180 degrees to bring an empty holder below the ring 48; so that the thread lies across it. As both bobbins are now rotating, the thread snaps and begins to wind on the empty bobbin. The reciprocation is now re-started so that the pins 52 engage their sockets to prevent the turntable rotating. A solenoid 56 is now engaged to advance a bifurcated member 60 to raise the filled bobbin holder out of contact with the conical member 30.

Title: Improvements in or relating to pulsed radar systems
Inventor: SCANLAN MICHAEL JAMES BARTHOLO
IPC: G01S7/36
Filed: 1958-09-25
Abstract: 906,502. Pulse radar. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. May 28, 1959 [Sept. 25, 1958], No. 30734/58. Class 40 (7). A radar system comprises a pulse transmitter, a frequency selective radio receiver, means for rapidly sweeping the selection frequency of the receiver through a frequency range including the transmitter frequency so that each received echo pulse causes the receiver to produce a series of output pulses at a P.R.F. determined by the sweep frequency, and means for using the output pulses for target indication. The aim of the system is to resist carcinotron jamming. In the system shown a master oscillator 1 controls a transmitter 4 which transmits 10 Ásec. pulses. Received pulses are mixed at 7 with the output of a local oscillator whose frequency is swept at 5 mc./sec. The mixer output is fed through an amplitude limiter to a gate 13 which is open for 25 mÁec. only at moments when the swept frequency is such as to combine with the transmitter frequency to produce a predetermined intermediate frequency. The amplitude limiter limits amplitudes to the value of the strongest echo signal expected, and the limit may fall from a high value after a pulse to a low value just before the next pulse. The output from the gate is fed to five parallel gates such as 15, 25, which open in succession for 1 Ásec. each under the control of multivibrators such as 17, 27. Each of these gates is followed by a chain of counters 18, and the outputs of the counters are fed in parallel to a coincidence detector 20 which provides an output pulse for target indication only if all five chains of counters have counted the same, predetermined number of pulses-in the present case, ten, since the local oscillator frequency has the correct value to produce the predetermined I.F. ten times in one Ásec. The counters are reset after every five Ásec. Means may be provided for producing a display only when successive echos occur at the same range. The transmitter and sweep frequencies may be variable.

[Also in Division H2] The output voltage of a bridge, comprising armature winding 11 and resistors 12-14, is applied, in opposition to a reference voltage from source 18, to an amplifier 20 controlling power transistor 21. If the back E.M.F. of the motor tends to decrease due to increased loading, the output voltage of the bridge will fall to increase the input voltage of the amplifier. The current supplied to the motor through the transistor 21 thus increases so that the speed is restored to a desired value. Temperature changes in the motor are compensated by making the resistor 12 of the same material as the armature winding and subjecting it to the same thermal conditions. The resistor 12 is shunted by resistor 22 or capacitor 23 to overcome inductive effects at high frequencies. A filter 24 is connected to the input terminals of the amplifier 20. In a modification, the resistor 12 is shunted by a potentiometer having its tap connected to a two-stage transistor amplifier. The transistor forming the first stage of this amplifier also provides the source of reference voltage at its base-emitter junction. In a further arrangement, a potentiometer is connected across a tapped portion of the resistor 12.
