Patent GB-743193-A (GB)
Title: Improvements in or relating to electrical communication systems which utilise frequency or phase modulation
IPC: H04J1/20
Filed: 1952-11-11
Abstract: 743,193. Telephone transmission systems. GENERAL ELECTRIC CO., Ltd., and STENNING, L. C. Nov. 11, 1953 [Nov. 11, 1952], No. 28404/52. Class 40 (4). [Also in Group XL (c)] In a frequency modulation system in which the audio signals are subjected to compression at the transmitter the degree of compression is signalled by varying the amplitude of the frequency modulated wave, a high amplitude indicating a low degree of compression and vice versa. As shown, Fig. 1, the audio input is applied to the variable gain amplifier 1 whose output is rectified to provide a compression bias in the amplifier. The audio output from the amplifier also frequency modulates the oscillator 2, whose output is applied to the limiter 4, part of whose output is fed to a frequency discriminator 5 whose output controls the centre frequency of the oscillator 2. The constant amplitude frequency modulated output is also passed through the variable gain amplifier 1. The resulting output whose amplitude reflects the degree of compression imposed by the amplifier is then fed to line. At the receiver the frequency modulated wave is fed to a variable gain amplifier 12 whose resulting output is rectified and fed back as a gain controlling bias to the amplifier in such a manner as to keep the amplitude of the frequency modulated output constant. The variation in gain of the amplifier 12 is thus made to compensate for the variations of gain in the transmitting amplifier 1. The frequency modulated output is fed to a discriminator 14 whose audio output is fed to the amplifier 12 for receiving the appropriate amount of expansion. D.C. signalling over the channel may be effected by switching in an additional condenser in a tuning circuit in the discriminator 5 to cause a shift of the carrier frequency which may be recognized in the receiver by an additional suitably tuned discriminator circuit (not shown). The arrangement is designed for reducing cross-talk in 16- channel carrier telephony groups passing over adjacent pairs of the same cable and in which the channels using the higher frequencies are given a larger amount of frequency shift than those using the lower frequencies in order to reduce further the cross-talk which is otherwise more pronounced at the higher frequencies. Specification 611,983 is referred to.

Title: Device for braking and stopping a spinning or twisting spindle in a specific position of the spindle rotor
IPC: D01H7/22
Filed: 1972-06-12
Abstract: 1339211 Precision braking devices with signalling particularly for double twist spindles PALITEX PROJECT CO GmbH 19 June 1972 [22 June 1971] 28561/72 Headings DID and DIF A spindle whorl 1 is driven by a tangential belt 2 held against it by a pressure roller 3. The roller 3 is mounted on a lever 15 swing- able about a pivot 17 by means of a spring 16 but restrained by a push rod 14 which is locked by a lever 13. The lever 17 is influenced while swinging by a delaying device 18, e.g. a pneumatic bellows. The apparatus acts as a stop motion responsive to a yarn tension sensitive switch 4 or a package size sensative switch 5. Activation of either switch operates a solenoid 7 to apply a spindle brake and a solenoid 8 to disengage the locking lever 13 from the push rod 14 hence allowing lever 15 to swing. This releases the whorl driving pressure of the belt 2 by withdrawing the roller 3 and brings a first stop 20 into register with the path of travel of a second stop 25 on the whorl 1, the spindle, however, being stationary at this time. Towards the end of the travel of the lever 15 a bellows release valve 21 is activated, a switch 29 gives a pulse to stop a wind up package driving roller 31 and a switch 6 releases the brake splendid 7 and locking lever solenoid 8 Thus the spindle is turned slowly (only low engagement pressure of belt 2) to an accurately predetermined position as decided by stops 20 and 25 to align, e.g. a threading up hole in the spindle. A switch 12, interconnected with lever 13, is also thrown to illuminate via switch 6 signal lamps 24. To restart spinning push rod 14 is pushed in to move lever 15 to its initial position, i.e. to give full whorl driving pressure and disengage the stops 20 and 25, see Fig. 3 (not shown). During start up while yarn tension is low, the stop motions are rendered inactive by switch 6 since it is controlled by a follow up lever 13 which returns only slowly by a spring 34 under the restraint of the bellows 18. Restart of the take up package driving roller 31 is similarly delayed. When switch 6 finally shifts it also extinguishes lamps 24. In an alternative embodiment, Fig. 6, the correct timed sequence as illustrated in Fig. 8 (not shown), is achieved by a geared motor driving cam discs which operate a lever 60 substituted for lever 15 a spindle brake lever 62 and switches 6, 64 and 29. Fig. 6 also shows a suitable internal expanding shoe brake in the hub of the whorl.
