Title: Determination of the centroid of charge in a dielectric body
IPC: G01R31/26
Filed: 1973-11-13
Abstract: 1400960 Locating centroid of charge distribution INTERNATIONAL BUSINESS MACHINES CORP 13 Nov 1973 [4 Dec 1972] 52613/73 Heading G1U By applying a pulse of A.C. (of the order of 100 kc/s) superimposed upon a D.C. bias across a dielectric, charge is injected into the dielectric, and the centroid of the distribution of charge that remains trapped in the dielectric at the end of the pulse is determined by measuring the amount of charge injected and the resulting change in potential across the dielectric. According to classical electrostatic theory the potential across a capacitor varies linearly with charge (V=q/c) and all the charge is thought of as lying on the surface of the dielectric. With modern semi-conductor dielectrics, this theory is too simplistic, since it is found that a current (holes or electrons) actually flows through the dielectric upon the application of a suitable potential across it, and moreover, that when the potential is removed some of the charge constituting the current remains trapped, even after the potential across the dielectric is restored to zero. The presence of this trapped charge, and its distribution, affect the capacitive properties of the dielectric.

Title: Optical system with holographic pattern formed within an electro-optic photoexcitable plate
IPC: G02F1/055
Filed: 1972-11-16
Abstract: 1412618 Dielectric storage arrangements THOMSON-CSF 16 Nov 1972 [19 Nov 1971] 53052/72 Heading H3B A hologram is written into, read out, or erased from a plate 14, Fig. 1, of electro-optic material having a polycrystalline structure and exhibiting ferroelectric properties below the Curie temperature, a bias being applied to the plate coincidently with incident light from a source 1 during the writing phase for producing a non-uniform electrical charge distribution corresponding to the phase hologram pattern. Holograms of an object 6 are formed in the plate in the usual manner by object and reference beams 10, 11, and are read out by the reference beam alone in combination with a viewing device 17. The bias may be an electric potential applied to electrodes 15 or may be a mechanical stress applied through an electromechanical transducer, Fig. 4 (not shown). Alternatively localized bias may be produced in the plate by concentric electrodes 32, 33, Fig. 5, which provide a radial bias field, or by two orthogonal sets of parallel strip electrodes 35, 36, Fig. 6, respectively arranged on opposite surfaces of the plate 14. A stored hologram may be erased by applying an alternating bias which is progressively reduced from normal intensity to zero. Two modes of operation are possible, depending on whether the plate 14 is below or above the Curie temperature. For operation below this temperature it is sufficient for the bias to be applied during the writing phase only, while at temperatures above the Curie point the bias is required additionally during the reading phase, to restore the electro optic properties to the crystal so that its refractive index variations accord with the stored charge pattern. Several holograms may be combined in the same plate by using a different bias amplitude or orientation or a different angle of incidence of the reference beam for each recording. The plate is formed from a ferroelectric polycrystalline ceramic containing metal impurities and requires a density differing from its theoretical density by less than 0À5%. One suitable material is a lead and lanthanum titanium zirconate, prepared by the sintering under pressure of samples having the composition where 0À02#x#0À07.

IPC: B21B37/52
Filed: 1965-12-28
Abstract: 1,163,274. Rolling. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 16 Dec., 1966 [28 Dec., 1965], No. 54934/65. Heading B3M. [Also in Division G3] In a continuous rolling mill in which the stands are independently driven, the torque developed by the drive of a given stand, when a workpiece is being rolled at a predetermined interstand tension, is compared with the torque developed when the workpiece is threaded into the next stand, and any difference is used to control the torque developed by the given stand in order to maintain the tension at a desired value. The comparison of the torques can either be displayed so that an operator can control the torque of the given stand or the succeeding stand, or can be used to operate a calculating device for determining the speed of the given stand to produce the desired torque. For automatic control, a digital computer may be used which makes alterations to the mill speed settings in accordance with a constant of proportionality for each stand, or alternatively, any torque difference may be amplified and applied to the drive motors. For an arrangement of stands having rapid response drives (Fig. 2) the torques are held at their initial values rather than calculating corrections for subsequent adjustments. A memory capacitor 5 is initially in parallel with a resistor 6 in the motor drive circuit, before the . next stand is threaded. The stand is run at a preselected speed V 1 , whose value is fed together with a signal from a tachogenerator 8 to a comparator 7. A relay A2 is tripped before the next stand is threaded so that the drive of stand 1 is controlled to maintain the torque (current) of the stand close to its initial value. Alternatively the speed of the most recently threaded stand is altered to adjust the stand torques to their previous values. The measured torques may be summed and adjusted proportionally to the sum, to maintain the correct interstand relationships in the event of changes in the yield of the rolled stock. Instead of maintaining the measured torque of a stand constant, the ratio of measured torque to rolling load may be kept constant.
