Title: Electro-magnetic testing of steel wire ropes and other articles of magnetisable material
IPC: G01N27/90
Filed: 1927-12-20
Abstract: 306,232. Wall, T. F. Dec. 20, 1927. Magnetic tests. - Steel wire ropes, rails, or other articles of magnetizable material are tested for flaws by means of a. magnetic system comprising a laminated iron core having a coil, preferably excited by alternating current, the magnetic circuit through the coil and the laminated core being completed through a portion of the article under test, a search coil being arranged to embrace a portion of the flux through this path. The laminated core L, Fig. 2, provided with a magnetizing winding E, has two limbs L', L<2> with clearance holes through which passes the steel rope &c. R to be tested. These limbs are formed with slots B<1>, B<2> extending below the hole and leaving narrow projections A<1>, A<2> on which are wound search coils S', S<2> connected in series so that their electromotive forces oppose one another in a circuit containing a voltmeter or an amplifier supplying an indicating or recording voltmeter or a string galvanometer. Normally the electromotive forces of the coils S<1>, S<2> balance one another but this balance is disturbed on passage of a flow, causing a resultant electromotive force, which is indicated on the voltmeter. Alternatively a single search coil 8. Fig. 4, may embrace both projections A<1>, A<2>, an electromotive force being generated by a difference in the fluxes in these projections. In another arrangement, the slot B<2> and coil S<2> are omitted, an opposing electromotive force equal to that normally generated by the coil S<1> being supplied by, for example, a transformer connected across the coil E. Fig. 4 shows a construction which can be applied to a rope in situ. The limb L', L<2> are divided through the centre of the holes through which the rope R passes, the outer portions being secured by non-magnetic clamping plates C after the rope is in position. The rope is guided by pulleys P. Instead of the search coil or coils being located in slots B<1>, B<2>, they may be arranged to lie either on the surface of the hole through which the rope passes, or embedded in a groove in this surface. One coil may be arranged in each half of the hole, the two coils being connected in series. The apparatus may then be applied to a rope in situ. According to the first Provisional Specification the magnetic circuit may be excited by direct current and a ballistic galvanometer connected to the search coil. A valve may be connected in the search coil circuit to eliminate the reverse throw. The balancing electromotive force may be provided by a second system provided with a length of rope similar to that under test. When using alternating-current excitation, the current coil of a wattmeter may be connected in series with the magnetizing coil and the pressure coil in series with the search coil.

Title: Method of and apparatus for regulating the temperature and conversi on in a polymerization reactor
IPC: C08F2/00
Filed: 1970-07-16
Abstract: 1310975 Automatic control of temperature & fluid flow rate SNAM PROGETTI SpA 16 July 1970 [21 July 1969] 34622/70 Heading G3R Relates to a method of regulating the temperature of and degree of conversion in a polymerization reaction in which at least one polymerizable monomer is fed to a reactor together with a catalyst dissolved or suspended in a liquid medium, by controlling the feedrate of the catalyst and the temperature of the liquid medium. In the drawing thick lines represent pipe lines for process fluids and thin lines represent electrical connections. Monomer is fed at a constant rate and temperature via pipe-line 1 to a reactor vessel 5 and the polymerized product is discharged through 6. A pipe-line 3 conveys a catalyst dissolved in a solvent, at a constant composition and temperature but variable flowrate. A line 4 conveys the majority of the solvent at a variable temperature, solvent streams in lines 13, 14 and at different temperatures being fed via a controlled mixing valve 12 and a combined stream at an adjusted temperature being fed to the pipe-line 4. The flow-rates in the pipe-lines 3, 4 are regulated by controlled valves 20, 16 so that the solvent and catalyst conveyed by line 2 to the reactor, flows at a constant rate. ELECTRICAL CONTROL ARRANGEMENT The reaction temperature is measured by a sensor 7 in the reactor or pipe-line 6 and is compared in a comparator 8 with a desired reaction temperature signal in a conductor 9. The comparator 8 output is compared in a comparator 10 with the solvent/catalyst temperature in pipe-line 2 and measured by a sensor 11. The resulting output from comparator 10 controls  the mixing valve 12 as described above, whereby the solvent temperature in pipe-line 4 and hence in pipe 2, is maintained at a value imposed by comparator 8. The flow-rate in pipe 2 is sensed by a unit 15 which controls valve 16 to adjust the flow-rate in pipe 4 in conjunction with any flow-rate changes in pipe 3, whereby to maintain a constant flowrate in pipe 2. A signal representing the desired degree of monomer conversion is fed via a conductor 21 to a signal processor 22, together with the desired reaction temperature signal in conductor 9. The processor 22 produces a control signal therefrom in a conductor 18. This signal is compared with the solvent/catalyst temperature sensed by 11, in a comparator 17, the output of which is fed as a reference value to a regulator 19. The regulator 19 also receives an input significant of the flow-rate of catalyst/ solvent in pipe 3 and regulates the said flow-rate accordingly, by means of the valve 20. Thus the reference control signal in conductor 18 is such that the difference between the temperature of solvent entering the reactor vessel 5 as measured by 11 and the temperature of product discharged therefrom as measured by 7, corresponds to the heat developed by the reaction in accordance with the desired degree of monomer conversion.

Abstract: 994,466. Semi-conductor pulse circuits. WESTERN ELECTRIC CO. Inc. Sept. 27, 1961 [Nov. 1, 1960], No. 34660/61. Heading H3T. [Also in Division G4] In a pulse generating and discriminating circuit a variable voltage V at point 115 causes a gate 130 to be open or shut and a variable repetition frequency pulse generator 121 to assume a frequency f dependent upon the difference between V and the normal value Vo of that voltage. A second generator 123 gives frequency #o, equal to # when V=Vo. The pulses are mixed at 122, the output, f # fo, being differentiated at 124. If V is less than Vo gate 130 is open and current flows in the direction 143 through tunnel diodes 141, 142 and only positive pulses can pass to amplifier 150. If V is greater than Vo gate 130 is shut and current 144 flows, this permitting only negative pulses to pass to the amplifier. The unit 121 comprises a tunnel diode 301, Fig. 3A, the voltage V being fed in via diode 304. Fig. 3B illustrates the variation of repetition frequency with change in V.
