Title: Magnetometric apparatus
IPC: G01R33/038
Filed: 1974-05-24
Abstract: 1440152 Magnetometer INST ZEM MAGNETIZMA IONOSFERY I RASPROSTRANE RADIOVOLN AKAD NAUK SSSR 24 May 1974 23433/74 Heading G1N In a quartz magnetometer in which a slowly varying A.C. voltage is applied to the deflection coils, and a mirror is attached to the magnet, a beam of light is reflected by the mirror on to a stationary photo-cell when the applied magnetic field compensates that being measured and the photo-cell output causes the applied voltage to be digitized and recorded. Three magnetometers 1, 2, 3 (one for each directional component) each have field coils 14, suspended magnets 5 and mirrors 6. The field coils are supplied with low frequency A.C. from oscillator 18 via resistors 15, 16, 17 in parallel with capacitors 25; 26 and 27, 29 respectively. Light from source 10 is reflected from the mirrors on to associated photo-cells 11, 12, 13 at equality. In operation, relay contacts 19, 20, 21 are initially closed. As each photo-cell responds, the associated holding relay 22, 23 or 24 is energized and locked and opens the contact 19, 20 or 21 respectively to isolate on the associated capacitor a voltage proportional to the magnetic field. When magnetometer 3 responds, the voltage on capacitor 29 is compared with that on 33 (which corresponds to that of a previous reading). If the voltages differ, that on 29 is transferred to 33 and the pulse generated by transformer 32 sets the recording mechanism in motion. This comprises a motor 57 which drives rotary switch 63 to sample the voltages on capacitors 25, 26, 27, feed them to analogue to digital converter 62, and then feed the digitized voltages to recorder 58. If the field on magnetometer 3 has not changed between measurements the voltages on capacitors 29 and 33 will be equal at the end of the measurement and no values will be recorded. In an alternative, digital embodiment with the magnetometers separated from the recording device, a digital sine wave values are transmitted to the measuring instruments where a sine wave is generated from them by a D/A converter. The photocell outputs are transmitted in frequency multiplex and these signals, after demultiplexing, are combined with the digital signals from the sine wave generator to give the magnetic field values.

Patent GB-872598-A (GB)
Title: Improvements in or relating to automatic thread winding machines
IPC: H01R13/66
Filed: 1957-07-30
Abstract: 872,598. Winding yarns. REINERS, W. July 30, 1957 [Aug. 6, 1956; Nov. 28, 1956], No. 24092/57. Classes 120(2) and 120(3) An automatic winding machine of the kind having a plurality of individual winding stations, a thread restoring mechanism operative to unite the two thread ends in the event of a thread breakage, or the exhaustion of a supply bobbin, and means to produce relative movement of the winding stations and thread restoring mechanism during which each station in turn is located in the zone of operation of the thread restoring mechanism, comprises means to arrest the said relative movement only when a winding station at which restoration of the thread is necessary is located in the zone of operation of the restoring mechanism. In the embodiment shown, hub 8, rotatable about a stationary pillar 7, carries several winding stations each mounted on an extending arm 9. In operation feeler lever 33 pivots clockwise on the absence of thread F causing contacts 35, 36 to close the circuit through magnet 39 so as to disengage friction roller 28 from drive roller 27 and thus arrest the rotation of guide drum 10 and package 12. The hub 8 continues to rotate until the contact pin 44 corresponding to the defective winding station engages stationary contact 45 thus energising magnet 48 which causes lever 49, 52 to rock in a counterclockwise direction and open contacts 59, 60 thus breaking the circuit to motor 64 and stopping the rotation of hub 8 with the appropriate winding station located in the zone of operation of the thread restoring mechanism. When lever 49, 52 is rocked, bell crank lever 53, 54 is released and pawl 55 engages one of the teeth of disc 57 thereby causing rotation of disc 51 to initiate the operation of restoring the thread in known manner. The restored thread returns the feeler 33 to the position shown and by the reverse process recommences the winding operation and the rotation of the hub 8. When package 12 reaches the required diameter, nose 20 on lever 16 runs off the quadrant 16 causing contacts 18, 21 to close to operate a signalling element 25. The above arrangement allows the thread restoring operation to be repeated indefinitely as long as it is ineffective i.e. if a fault has occurred in the knot tying mechanism. To overcome this, in another embodiment, a heating coil co-operating with a bi-metallic strip is included in the electric circuit so that the thread restoring operation is repeated only for a predetermined time, after which the driving motor 64 is started and a signalling device is operated to indicate a fault in the thread restoring mechanism. In a further embodiment provision is made to eliminate the thread restoring operation e.g. when a thread breakage occurs when the package is almost of the required size. Specification 872,222 is referred to.
