[Also in Group XIX] An information store comprises a magnetic core matrix, a magnetic core counting chain for impulsing successive columns of the matrix, and means for applying impulses to selected rows of the matrix so as to store or read out information in serial binary form. In the matrix M shown, each row has an associated writing line L1 . . . Lm, Fig. 1. The counting chain, which comprises cores B1 . . . Bn and A1 . . . An pulsed alternately from lines I and II (see Fig. 3) supplies a pair of read/write pulses sequentially to matrix column lines aI . . . an. In the system shown in Fig. 2, the read pulses from the counting chain KK cause the binary information stored in the row selected by the address decoder AE to be applied in serial form (pulse for " 1," no pulse for " 0 ") to a common read-out line L (li in Fig. 3) from which it may pass, via an amplifier and a regeneration path Reg, both to an output Ag and to a circuit Mi which may also receive new information from an input Eg. The circuit Mi is controlled also by clock pulses from a source U and supplies a serial train of pulses (pair of pulses for " 1," single pulses for " 0 ") to the selected writing line (ri, Fig. 3); the second pulse of a pair coincides with a write pulse from KK whereby each " 1 " is written into the appropriate core of the row. Reference is made to simultaneous operation of several rows having separate read/write circuits.

Filed: 1971-07-23
Abstract: 1363283 Mixing apparatus controlled by power consumption G LIMBURG 23 July 1971 [18 May 1971] 34651/71 Heading BIC [Also in Division G3] In apparatus for adding water to clay the current consumed by the mixer driving motor is used to control the supply of materials to obtain constant plasticity of the mix. As shown a mixer I is supplied with solid material by a conveyer belt 10 and water through on-off solenoid valves 7, 8, 9. The current consumed by the mixer-motor 2 is fed into a control circuit 5 through an instrument transformer 13 3 having a standard normal secondary current valve, e.g. 5A, the A.C. being fed into a device 14 which converts it into a D.C, signal by measuring the heating effect of the A.C. and smooths out minor fluctuations; the D.C. is fed to a controller 6 which operates the valves 7, 8, 9. A time delay 12 prevents the control circuit from responding to the motor starting current. A timer 11 starts to run when the water content of the mix falls below the preselected value and stops the belt 10 if the deficiency persists. In modifications the water may be supplied through a single servocontrolled regulating valve, or the regulation may be applied to the solid materials.

Abstract: 1,235,982. Making glass beads. POTTERS BROS. Inc. 14 July, 1969 [19 July, 1968], No. 35434/69. Heading C1M. Glass beads are produced by mixing crushed glass with a binder, applying thereto a finely divided solid which will act to prevent agglomeration of the particles when heated, mixing the coated particles with a finely divided inert material which has substantially the same S.G. as the particles and heating the mixture to 1400 to 1750 F. whereby the glass particles soften and assume spherical shape by surface tension. Thereafter the beads are separated from the inert material, e.g. by sieving the inert material through a shaker screen, and may be further treated, e.g. by oil-quenching at 1250 F. Suitable binders are natural gums and synthetic resins (examples given), the preferred binder being a paracoumarone-indene resin "Cumar". Suitable finely divided solids are graphite (preferred), SiO 2 , MnO 2 , CuO, MbO 3 , ZrO 2 . Reference is also made to coating particles first with arsenic oxide or MnO 2  and then with graphite. A suitable inert material is a 50/60 mixture of MgO and graphite. Apparatus for performing the process continuously is described in which the heating is carried out in a rotary calciner inclined to the horizontal and through which the complete mixture moves slowly from the upper (charging) end to the lower (discharge) end.

Abstract: 748,528. Welding by pressure. MAGNETIC HEATING CORPORATION. Dec. 22, 1953 [Jan. 21, 1953], No. 35615/53. Class 83 (4). [Also in Group XI] In welding the edges of a longitudinal gap in a metal tube, the tube is advanced longitudinally and pressure is applied to close the gap at the welding point, the gap edges being heated by applying a high frequency current of at least 10,000 cycles per second to the tube by electrodes which engage the tube on or near the gap edges and such that the greater part of the current flows along the edges, which form the lowest impedance path between the electrodes, to the welding point. The tubing is fed to rollers 13, 14 where the gap 11 is closed and welding effected at point 12. Current at frequency of 10,000-500,000 cycles per second is supplied to a block 21 carrying a contact 15 in sliding contact with one of the gap edges and flows along the one edge of the gap to the point 12 and along the other edge to a contact 16 insulated from contact 15. Current flows from contact 16 along a hollow hair-pin conductor 30 extending close to the edges of the gap and then to a block 22a. The current in the conductor 30 flows in opposite direction to that in the gap edges and reduces the inductance of the path along the edges. Additional insulated rollers 25, 26 may be used to ensure good contact with the contacts 15, 16. A cooling fluid is circulated through the blocks and through the hair-pin conductor. The contacts may be offset, contact either the inner or outer tube surfaces or be provided by rollers.

Abstract: 749,894. Synchronous machines. PESTARINI, J. M. Nov. 29, 1954 [Dec. 22, 1953], No. 35635/53. Class 35. The field winding 20 of a synchronous motor or generator S is excited in response to load changes by a metadyne exciter M2 which is controlled by a pilot metadyne exciter M1, both machines being fed at their primary brushes a, c from battery Bt through a switch H which may be operated to shortcircuit their primary axes to enable them to act as generators. A device 30 connected to the alternator output is responsive to load changes and produces control current Ip, fed to pilot exciter field winding 5 and, if desired, a further error current Ie fed to main excitor winding 98. Field winding 6, which opposes winding 5, and may be combined with it to form a single winding, is fed from an outside source with a current Ir proportional to the desired value of the output of generator S, so that the output of the generator is proportional to the resultant energization of these two windings. A transformer F eliminates induction between field windings. Field windings 1 and 90 are connected in series with the primary brushes of excitor M1 and serve to oppose and augment respectively the armature ampere-turns due to the primary current. Shunt excitation winding 3 produces a voltage across primary brushes a, c substantially equal to the voltage of battery Bt, while secondary current armature reaction is compensated by winding 9. Further control windings 7, 77 may be used if desired. The output of the exciter M1 is fed to field winding 25 of exciter M2, which also may have a shunt winding 23 backing the battery voltage. Field winding 21 creates an E.M.F. opposing the primary current while winding 22 which is traversed by secondary current and produces a flux opposing that current while winding 29 produces under-compensation for secondary current. In a modification, greater stability of operation is achieved by the use of two similar exciting systems feeding alternator field coils in quadrature. The control currents Ip and Ir may be controlled by auxiliary generators.
