Abstract: 756,028. Electric control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 12, 1953 [July 12, 1952], No. 17638/52. Class 40(1) [Also in Groups VIII and XXXV] The quality of the fabric knitted on a circular knitting-machine is maintained substantially constant or regulated by providing electrical apparatus which compares the speed of the yarn being consumed with the speed of the machine. Any variation from a datum is exhibited and is capable of use in operating regulating means to adjust, while the machine is running. the rate of consumption of the yarn. A comparator circuit comprises two component circuits with their outputs in opposition and in one component circuit there is provided a capacitor 29 which is alternately charged from a supply 30 through contactor 21, rotated by the yarn, and discharged into a capacitor 31 of higher value. Across this capacitor 31 there is provided a resistor 32 through which the capacitor 31 discharges. A current proportional to the speed of the yarn, therefore, flows through the resistor 32. A similar component circuit is also provided containing the machine-driven rotatable contactor 26 and comprises capacitors 34, 35 and resistor 36 whereby a current proportional to the machine speed flows through resistor 36. If the currents are of equal value and the resistors 32, 36 have equal value, the potential difference between the points X and Z will be zero and an indication is given on a meter 37. If at any time the relative speeds become out of synchronism a potential difference between the points X and Z will exist and will cause an indication to be given on the meter. Such an indication may be used to enable manual adjustment to be made to the machine to bring the two speeds back into the desired relationship. Alternatively automatic means may be provided for making this adjustment. A circuit breaker or machine stop motion switch 40 may be provided in the circuit and is operated in the event of yarn breakage.

Abstract: 771,947. Power measurement. POLYTECHNIC INSTITUTE OF BROOKLYN. June 20, 1955, No. 17793/55. Class 37. [Also in Group XL (b)] Wave energy whose power is to be measured is propagated through wave-guide section 1 (Figs. 1, 2), dimensioned. appropriately to the frequency band to be measured, which is alignedly, coupled by flanges 1a, 2a to a waveguide section 2 of greater dimensions (preferably the same width but twice the height) than section 1. The sections are insulated by a thin (e.g. mica) sheet 3 interposed between the flanges on whose forward face are mounted two vertically aligned metallic strips 4, 5 centrally connected by a bolometer wire 8a, 8b comprising a thin platinum core silver covered at its ends and etched away at the centre to leave a platinum filament 8. Strip 4 is clamped to flange 1a, and strip 5 is connected through an opening in sheet 3 to a strip 6 clamped to flange 2a, so that the sections may be connected to a Wheatstone bridge measuring the bolometer resistance and thus the wave energy in known manner. Strips 4, 5, 6 are replaceable by lines of silver paint on sheet 3. Waveguide section 2 is terminated in a matching energy dissipating load, preferably a tapered resistive plate 9, mounted within the guide with its plane parallel to the electric field. A mathematical analysis is given, and it is shown that in a preferred design introducing a 3 lb. power loss, equal proportions of input power are dissipated in the bolometer and in the load of the output waveguide section, whose impedances are equal at twice the characteristic impedance of the input waveguide section; and that the height of the output guide section is twice that of the input guide.

Abstract: 637,878. Magnetic tests. LUNDBERG, H. T. F. July 10, 1947, No. 18329. Convention date, Nov. 1, 1944. [Class 37] [Also in Groups XXXVIII and XL (c)] Apparatus for geophysical exploration consists of a fluid-supported craft, e.g. an aircraft, which carries instruments responsive to variations in the magnetic field or the distance of the deposit, these instruments being stabilized for orientation and level and feeding recorders, so that as the craft traverses the area being investigated records are made to indicate the location of deposits. Magnetic variations.-A stabilized inductor compass may be used. Alternatively a flux gate compass comprising a nickel-iron core in a solenoid fed with A.C. may be used ; the permeability of the core is varied by the magnetic field and the variations in impedance of the solenoid are detected by a bridge circuit. Alternatively, magnetrons sensitive to variations in the earth's magnetic field may be used ; two diode magnetrons 1, 2, Fig. 1, having their cathodes 3, 4 within cylindrical anodes 5, 6 and positioned within solenoids 19, 10 and 11, 20 respectively are adjusted to be at the critical point of their characteristics ; any variation of the earth's field will then produce a variation in anode current which will be recorded at 9 ; the solenoids 10, 11 oppose the effect of solenoids 19, 20 ; preferably the anodes of the magnetrons are at right angles so that any diurnal variation effects both equally and is eliminated, but variation in the desired direction affects one only ; switches 13, 14 permit magnetron 2 to be disconnected when the measurements are not required to be very sensitive. The magnetrons may have grids, Fig. 2 (not shown). Distance variations.-An ultra-high frequency oscillator 34, Fig: 3, is keyed to supply pulses to aerial 38, the pulses reflected from the earth being received at 48 and delineated on a recording cathode-ray tube 46. As shown in Fig. 4c, reflections 49 are due to the earth's surface and reflections 51, 50 are produced by deposits below the surface. Keying transmitter.-Oscillator 43, Fig. 3, produces the keying frequency which is applied to synchronize the time base of the cathoderay tube 46 and' is also applied to double diode 40 which is biassed to produce short pulses in resistance 39 which are applied to valve 36 to render it conducting and energize the oscillator 34 from source 35.

Title: Formation of battery plates
IPC: H01M4/04
Filed: 1972-04-20
Abstract: 1393726 Forming battery plates Mc- CULLOCH CORP 20 April 1972 [23 April 1971] 18356/72 Heading H1B [Also in Division G3] A method of rapidly forming battery plates comprises applying a formation current to the plates immersed in an electrolyte and intermittently applying the current in the reverse direction for a time sufficient to cause depolarization of the plates and/or electrolyte without significant discharging of the plates. Suitably the current is reversed on the occurrence of one or more changes in the characteristics of the plates as formation proceeds, e.g. the potential of either plate, the voltage between them, the amount of gassing, the composition, colour or weight of the plates, the temperature of the plates or electrolyte and the composition and specific gravity of the electrolyte. These changes may also be used to indicate completion of formation. The changes may be observed visually and the current reversed manually, or they may be monitored for automatic electrical control (Fig. 2, not shown). Alternatively, current may be reversed intermittently according to a preset programme (Figs. 2 and 3, not shown). The method permits much higher forming currents and shorter forming times, and the density of the forming electrolyte may be such that it may be used as the working electrolyte. Preferably the cell voltage is maintained above the decomposition potential of the electrolyte during passage of the forming current and below this but above the open circuit voltage during current reversal. The maintenance of these voltages may also be controlled automatically (Fig. 5, not shown).
