Title: Improvements in lime feeding processes and apparatus for preparing and feeding the lime
IPC: C02F1/52
Filed: 1948-09-08
Abstract: 669,188. Purifying water. MOORE, R. P. Sept. 1. 1949. [Sept. 8, 1948] No. 23630/48. Class 46. Lime is prepared for feeding, e.g. to a water softening plant by mixing the lime with a body of water and allowing it to settle to the bottom of the water body to a substantially constant water-to-solid ratio and thereafter withdrawing the settled lime for feeding without material change of the water-to-solid ratio. The lime is allowed to settle for a period of from 2 to 6 hours. As shown the lime is mixed with water in a tank 2 and the resulting pulp is run as through pipe 10 into a second tank 3 preferably of conical form for settling. The settled lime is withdrawn from the tank 3 by means other than the weight of the settled lime itself, as through a discharge pipe 25 connected downstream of an orifice 31 in a closed water conduit 29, while a pipe 11 is connected to the top of the tank 3 and to a point upstream of the orifice 31 so that the lime is drawn into the conduit 20 at a constant rate depending upon the flow of water in the conduit 29. The place of the lime drawn from the tank 3 is taken by water entering at the top of the tank 3 through the pipe 11 and is measured through a meter 16 as an indication of the quantity of lime drawn from the tank 3. Only a portion of the settled lime from the tank 3 may be withdrawn during an operation and a further supply of the pulp run into tank 3 for settlement before the next operation. A discharge pipe 22 communicates with the tank 3 at a point intermediate its length to enable displacing water to be discharged. In a modification of the apparatus the water taking the place of the discharged lime from the tank 3 is supplied to the top of the tank 3 from a reservoir above the tank.

A brake pedal 1 is interlocked with the electric controller so that on depression of the pedal regenerative braking ensues, the pedal also closes contacts 3. When regenerative braking falls to a low valve a relay 7 in the regenerative braking circuit closes contacts 4. A circuit is thus closed through contacts 3, 4 and an electromagnet 9 which operates an air brake valve 11 by means of a lever 10. The valve 11 may also be operated by direct engagement of a projection 14 with the lever 10. Contacts 8 of a regenerative contactor are operated under the control of the pedal 1 to complete the regenerative circuit so tnat the coil 7 is only energized when regeneration takes place. Alternatively the brake controller may close contacts in series with the contacts 4 and with auxiliary contacts of the contactor 8. A relay is adapted to terminate regeneration at a low speed by opening the contacts 8. Specification 417,502 is referred to.

Abstract: 1,149,654. Radio position finding. MARATHON OIL CO. 27 May, 1966 [1 June, 1965], No. 24037/66. Heading H4D. The position of a material interface, e.g. A, between the atmosphere and a layer of kerosene 3, and B, between the kerosene and a column of water 2 is determined by immersing a transmission line 4 in the material, of such a type that the material becomes the dielectric of the line, and an impedance discontinuity appears at each interface. As shown the line is an air spaced coaxial cable, holes 19 allowing the material to pass into its interior. Thus by passing a sharp rise-time electric pulse down the line, the interfaces will reveal themselves by reflections, the positions of the interfaces being given by the time lapse between the transmission of the pulse and its echo. The echo detection is shown as being by a walking strobe and a C.R.T. display, shown as a stepped display, Fig. 2, with the depth of the discontinuity measured in the horizontal by means of a superimposed grid and the impedance of the material measured in the vertical. A preferred arrangement uses a commercially available apparatus called " Time Domain Reflectometer ". The transmission line may alternatively comprise a parallel wire line, or the outer conductor of the line may be the metal container 1. Several lines may be used in different materials and switched in sequence to the time measuring apparatus or simultaneously, using a multi-display split screen C.R.T. In an alternative time measuring system, the transmitted pulse opens a gate connecting an oscillator to a cycle counter, and the echo pulse closes said gate.

Abstract: 1,195,165. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 30 May, 1969 [21 May, 1968], No. 24243/68. Heading G6C. A nuclear reactor, in particular a gas-cooled reactor, has means for generating foam for blanketting any reactor component whose failure could result in loss of reactor coolant driving operation. In the case of a gas-cooled reactor the rate of coolant loss is slow and it is possible to erect tempoarary pens of wire mesh to hold the foam where it is required. Permanent pens may however be provided, e.g. the ends of standpipes can be situated in a recessed charge face with a raised surround to form a wall for the foam, or the charge face can be flat with recesses for posts to support a wire mesh structure for penning the foam in place. The recommended foam is a CO 2 -filled high expansion aqueous foam. The foam generating means can be a permanent installation with foam branches, or a portable foam generator. The latter will enable foam to be inserted into ruptured piping to plug the piping. The foam serves to prevent release of radio-active materials and aspiration of air into the pressure vessel.
