Abstract: 938,471. Anodes for preventing corrosion; indicating liquid levels. CATHODIC CORROSION CONTROL Ltd. Oct. 14, 1959 [July 14, 1958], No. 22563/58. Class 123 (1). A power-impressed cathodic control system for giving continuous internal protection to metal containers such as the tanks of oil tankers against electrolytic corrosion comprises a number of lead alloy anodes one of which is indicated at 5 each anode being mounted within a tank 3, containing e.g. seawater ballast 3, at the end of a liquid-tight support 7 passing through apertures in, and secured to, the roof 1 of the tank. A direct current source of electric power is connected to a contactor 13 the negative pole leading through a line 14 to the roof 1 and the positive pole being connected by a line 15 to the anodes 5 within a fluid-tight housing 8 secured to the roof 1. An auxiliary anode 9 is supported adjacent the upper end of the roof by an insulator 10 so that, when the seawater rises to a level 4, the anode 9 is immersed to produce a galvanic current which flows from the auxiliary anode 9 through lines 17, 18 and a relay 16 to the tank and the seawater electrolyte. Operation of the relay 16 actuates a slave relay 19 which influences the contactor 13 so that power is supplied to the anodes 5. Apparatus 21 may be provided in the auxiliary anode circuit to operate an indicator when galvanic current flows. Similar apparatus 22 may be incorporated in the circuit of the auxiliary anode 22 to indicate when the anodes 5 are energized. The indicator in the auxiliary anode circuit may be used to control the pumping apparatus for filling the tank. In a modification elongated cable-type lead alloy anodes are employed each anode being supported by electrically insulating members from a wall of the tank and the end of the anode being passed through the roof 1 with its upper end coated with an insulating sheath. The end of the anode below the normal level of the water is sealed off. In a further modification each anode comprises a freely suspended loop supported at each end from the roof 1.

In reacting a solid particulate material with a gas or liquid, there is employed a reactor comprising a plurality of tubular elements joined together in end-to-end disposition, each element being axially inclined relative to the preceding element. Fig. 4 shows a preferred construction in which the elements 1<SP>1</SP> have a generally rectangular cross-section with some chamfered corners. Fig. 2 shows an arrangement in which the solid material is introduced by a worm 9 into a portion of an apparatus comprising a plurality of adjacent reactors (of which only two, 4 and 5, are shown) above which a fluidized bed is formed: gas is introduced below the reactors through throttles 7 and pipes 8. Solid material is withdrawn by means of the conveyer belt 7 after reaction, any excess solids being removed at overflow 11. Fig. 3 illustrates a similar pair of reactors 16, 17 to which solids are fed from fluidized bed 18 and from which reacted solids are withdrawn by entrainment and passed to separators 19 where gases are removed. The amount of fluid which may be used is greater than that in fluidized beds due to the establishment of a stable circulatory flow of solids in the individual tubular elements.

Filed: 1973-05-14
Abstract: 1429886 Measuring velocity photo-electrically INFORMATION STORAGE SYSTEMS Inc 14 May 1973 [24 Aug 1972] 22919/73 Heading G1A The velocity of a member moveable along a predetermined path is obtained by generating a plurality of position signals responsive to movement of the member past predetermined positions spaced along the path, differentiating the position signals and sampling the position signals so as to obtain a continuous output velocity signal. The velocity of movement of a pair of recording heads 5, 6 across the surfaces of rotating discs 9, 10 is determined by positioning a grid 11 having opaque lines 12 on a transparent plate 13 on the head drive system driven by actuator 8. A fixed grid 14 is positioned adjacent grid 11 so that light from LED's 17, 18 can pass through the grids, in dependence upon their relative positions, to photodiodes 19, 20, the opaque lines on grid 14 being such that the output from the diodes 19 are 90 degrees phase shifted and of the form shown at P1. The diode outputs P1 P3 together with their 180 degrees phase shifted forms, P2, P4 inverted at 24, 25, are each differentiated at 26, 27, 28, 29 to  have waveforms 31 or similar phase shifted waveforms representative of velocity Fig. 2 (not shown). In order to obtain a continous velocity signal 57 at the tachometer output each differentiated signal is applied through a respective gate 51, 52, 53, 54. The gates are opened sequentially for a predetermined time corresponding to the linear portion of each cycle of the waveforms P1, P2, P3, P4 by switch controls 36, 37, 38, 39 so that with the addition of the signs at the output waveform 57 is derived. The switch control circuits are activated by threshold level detecting circuit 35. To reduce the effect of varying signal strength a hysteresis effect is introduced into circuit 35 by closing switches 55, 56 under the control of switch control 58.
