Title: Electric indicating control systems
IPC: B66B1/36
Filed: 1932-12-06
Abstract: 413,269. Gauging - apparatus. BARON, H., 231, Strand, London.-(Fitzgerald, A. S.; 433, Warwick Road, Wynnewood, Pennsylvania, U.S.A.) Dec. 6, 1932, No. 34584. [Class 106 (ii).] The distance between two relatively movable objects is indicated or controlled by the current produced as the result of light from one of the objects falling on a photo-electric system on the other. The arrangements may be duplicated in such a way that the distance is measured by the ratio of one current to the other and this ratio may be expressed as a single current by means of a bridge of saturable re-actors. The invention is described as applied to an elevator indicating system. As shown in Fig. 1, lamps 7<1> and 8 mounted at the bottom and top of an elevator shaft act on cells 9<1> and 10 mounted below and above the car so that the photoelectric currents produced vary with the position of the car in the shaft. Alternatively lamps 7 and 8 mounted at the top of the shaft may act on cells 9 and 10, the beams from the lamps being divergent and convergent respectively. To prevent interference the lamp 7 and cell 9 may be connected to the opposite phase to lamp 8 and cell 10 as shown in Fig. 2. The currents produced may be fed to ratio-type indicating instruments or may be fed through amplifiers 11 and 12 to re-actors 15 and 16 which are in a bridge with re-actor 17 and inductance 18. When the bridge is balanced no current flows in transformer 34 and, by means of the valve circuit shown, the current in winding 20 is adjusted to maintain the balance, this current being fed through indicating instruments 21, 22, 23, 24 in series which are calibrated to indicate the position of the lift. Specifications 400,206, [Group XXXV], 411,831, [Group XXXVIII], and (in the Provisional Specification) 404,034, [Group XXXVI], are referred to.

Title: Magnet system
IPC: H01F7/20
Filed: 1975-08-20
Abstract: 1524835 Electromagnets; permanent magnets PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 Aug 1975 [23 Aug 1974] 34603/75 Heading H1P A magnet system for exciting YIG tunable components comprises (Fig. 1) electromagnet polepieces 2, 2<SP>1</SP> energized by a coil 3 separated by an airgap of length L to produce a field HO=J#/L where J# is the flux of the coil; a plate 1 of high permeability magnetic material being inserted partially within the gap having a saturation magnetization less than the minimum field of the gap. It is shown by mathematics that where H 1  is the field derived from plate 1 of thickness d, H 0  is the field in the gap of width L, 4#M s  is the saturation magnetization of the plate. Plate 1 may be semicircular and of ferrite comprising gadolinum + aluminium, gadolinum, dysprosium, holmium substituted garnet; with saturation magnetization constant with tempera ture. The field strength component in the Z direction varies as shown in Fig. 3, along the X axis of the gap, and polepiece 2 may be notched at 4 to increase the steepness of the flanks of the curve plateau representing H 0 , H 1 . This enables the Y1G components to be arranged more closely to each other due to the extension of the homogeneous range of the field strength variation.  The pole faces 2, 2<SP>1</SP> may be stepped (Figs. 4, 5, not shown) to produce critically differing magnetic fields to compensate frequency differences between a Y1G filter and a Y1G oscillator respectively located in adjacent fields. Where a thicker disc 1 is required, this may be divided into two parts located on the respective polepieces (Fig. 6, not shown). Three distinct and differing magnetic fields with constant differences may be produced by applying segments of discs 1 to 6 of materials having different values of 4#M s  (Fig. 7) or segments of discs 1, 1c of the same material but of differing thickness (Fig. 8).  The magnet system may alternatively comprise permanent magnet excitation using mechanical shunt variation of absolute field strength while similarly maintaining constant the difference between the strengths of the several divided fields.
