Title: Apparatus and method for monitoring the square of the strength of a magnetic field
IPC: G01R33/02
Filed: 1974-03-01
Abstract: 1464656 Measuring magnetic fields LKBPRODUKTERAB I March 1974 [1 March 1973] 9481/74 Heading G1N In a device for measuring strengths of magnetic fields of the type described in Specification 1288946 means are provided for damping oscillations at the mechanical resonant frequency of the oscillating system. Four resiliently mounted conductive rods 2 connected in series by springs 3, 4 are energized by A.C. across 6, 7 having a frequency higher than the mechanical resonant frequency of the system. The voltage induced in the conductive rods 2 due to their movement in the magnetic field is detected by means of a secondary circuit including four conductive rods 8 mounted by springs 9, 10 so as to move with rods 2. Comparator 14 compares the voltage induced in the secondary circuit with a reference voltage derived from the voltage across capacitor 5 in the primary circuit and adjusted by tapped potentiometer 13. Phase sensitive amplifier 15 detects any output from comparator 14 and causes the potentiometer tap to be moved to zero the output from 14, the position of the tap being a measure of the square of the strength of the magnetic field. In order to prevent harmonics of the A.C. being induced in the secondary circuit due to exterior mechanical vibrations comparator 14 is connected via a feedback path to the primary circuit, which either includes a 180 degrees phase inverter (filter 17) or amplifier 11 is arranged to provide the inversion. Thus damping occurs for the signals produced by the system oscillating at its resonant frequency. Since the voltage generated at the output of amplifier 11 will depend upon the magnetic field and in order to avoid self-oscillations in the feedback loop divider network 16 is provided to damp the feedback signal, which divider divides the signals from comparator 14 with the output from amplifier 11 only when this latter signal exceeds a certain value. The filter 17 may be of the active type which in addition to the 180 degrees phase shift for the signals at the resonant frequency of the system also provides a 90 degrees phase shift for signals at the frequency of the supply.

Title: Improvements in apparatus for measuring webs of fabric
IPC: B65H23/192
Filed: 1939-03-29
Abstract: 526,926. Automatic tension control systems. SEABROOK, H. (Gessner Akt.-Ges., E.). March 29, 1939, No. 9855. [Class 38 (iv)] [Also in Group XL] Relates to apparatus for measuring webs of fabric comprising a measuring drum m to which the web W is fed by rollers c with the formation of a loop St so that the web is not subjected to tension while being drawn over drum m by rollers a driven by a constant speed motor II. According to the invention, the loop St is made to obstruct light to one or more photo-electric cells to an extent depending on the length of the loop in order to control a motor I driving the rollers c to maintain the length of the loop substantially constant. In the arrangement, Fig. 1, two cells 3, 4 are used between two lamps 1, 2 ; and in the normal position, the loop St obstructs the light to cell 3. If the loop shortens light falls on cell 3 as well as on cell 4, and if the loop lengthens light is cut off from both cells. The cells control switches 10, 11 and 5. 6 which latter pair is connected to a resistance 9 in circuit of motor I, which is speeded up or slowed down to maintain the loop in mid position. In a modification a single cell is used to speed up the motor when loop shortens and slow it down when loop lengthens. Reference is made for similar photo-electric devices to Specification 438,801, [Group XX], and U.S.A. Specifications 2,050,315 and 2,060,634.
