Patent ES-345072-A1 (ES)
Title: Magnetic calender
IPC: F16C39/06
Filed: 1967-09-14
Abstract: To vary the pressure between two rolls 2, 34 in a machine for pressing flexible materials, e.g. paper or textiles, the roll 2 comprises a shell 4 rotatably mounted in brackets 16 on a frame, and a shaft 6 rigidly carried by rods 24 on the frame, the shaft carrying magnetic means 8 eccentrically within the shell to attract one side of the shell towards the shaft and hence to force the diametrically opposite side into contact with roll 34. The magnetic means 8 may be a permanent magnet, a single electromagnet, or a plurality of series-connected electromagnets, and the current to the electromagnets may be varied to vary the force exerted by the shell 4 on the roll 34. This force may alternatively, or additionally, be varied, to take account of varying thickness and/or density of the flexible material, by means of a strain gauge 32 which, on any change in the pressure between shell 4 and roll 34 from a preset value, automatically actuates a motor 30 to adjust a bar 28 to raise or lower arms 26 carrying rods 24. To compensate for any deflection of the roll 2 due to its ends being fixed, the shaft 6 is attached at each end to mountings 18 which in turn are attached to a tension bar 20 provided with an adjustment 22, the bar 20 exerting a force on the shaft mountings in opposition to the stress created by magnet 8. The tension bar may therefore be utilized to give no deflection of the shaft when the magnetic force is exerted, or to give a positive or negative crown to the roll. Cooling or heating fluid may flow through either roll 2 or 34. When the roll 2 is utilized for heating or cooling, the fluid may be introduced and withdrawn at one or both ends, the inlets or outlets being formed at the top or bottom of the roll respectively. The flexible material may be forcibly drawn through the gap between the rolls, or either roll may be driven.

Patent ES-355976-A1 (ES)
Title: Method and apparatus for automatic measurements of corona inception and extinction voltages
IPC: G01R31/58
Filed: 1968-07-10
Abstract: In a method of testing corona inception (or extinction) voltage in an insulated power cable 10, an alternating test signal of steadily increasing (or decreasing) amplitude (from a source 26) is applied to the cable, the first and third quarter cycles of the test voltage being sampled for a corona discharge signal, the voltage of the test signal at which corona occurs being measured only when the corona discharge appears or disappears on each of a predetermined number of consecutive half cycles of the test signal. True corona should appear as a signal in the same position in successive half cycles of the waveform of the applied signal particularly in the first and third quadrants. The waveform is therefore examined for corona by a system 26 at the same position in each of e.g. five successive half cycles, and only if apparent corona is detected in each of these is true corona regarded as having occurred, as distinct from noise. As soon as true corona is detected, as the amplitude of the applied signal increases, a gate 114 is opened to pass the applied signal (appearing at point 50) to a voltmeter 116, to record the corona inception voltage. A signal related to apparent corona is developed at the point 58 by a filter and amplifier system 40- 46. The apparent corona discharge signal at 58 is passed to a gate 62, which is controlled to open by the generator 64 at the same time in each half cycle of the input, and thence to a comparator 72, which passes signals above a certain level, thus allowing the sensitivity of the system to be adjusted Thereafter the signal is applied in successive half cylces of the input to a series of flip-flops 88-96 which contains bi-stables designed to change state for 2, 2, 1, 1 and a cycle respectively. These gates 98-106 in a series chain for these periods respectively, so that if a corona signal does appear in each successive half cycle, a signal from a supply 108 will pass to operate a flip-flop 112 and open the gate 114. For measuring extinction voltage the system is designed so that the flip-flop 112 operates in reverse manner.
