Title: Treatment of liquids with corona wind discharge
Inventor: CARSWELL JOHN LAMAR
IPC: C02F1/40
Filed: 1960-10-05
Abstract: <PICT:0916757/III/1> <PICT:0916757/III/2> <PICT:0916757/III/3> In the separation of a water-in-oil emulsion into its component parts, the emulsion is introduced into a vessel 1 through a conduit 2 and passes upwardly through a metal screen 7 toward a downwardly directed corona wind discharge developed by an electrode assembly 11.  A baffle 3 assists in dispersing the emulsion which is confined to a central position 6 by an annular baffle 4.  The electrode assembly is charged oppositely to the baffles 3, 4, the screen 7 and the vessel 1. Loosely held water may separate out within the central portion 6 but water particles in the emulsion which pass through the screen are urged by the wind discharge on to the screen where they coalesce and gravitate to the bottom of the vessel 1.  The oil flows outwardly, from the portion 6, substantially without turbulence, and the remaining water drops also gravitate to the bottom of the vessel. The separated-out water forms a layer 24 of which the level is maintained by electrodes 20, 21 and a valved take-off conduit 19. The oil flows over a weir 8 into a basin 9 and out of a spout 10. A hood 16, preferably of a synthetic resin, encloses the electrode assembly and forms a gas-seal with the oil in the basin 9.  Air may be evacuated through a conduit 23 and replaced by another gas, e.g. hydrocarbon gas contained in the incoming emulsion.  In the construction shown in Fig. 2, the emulsion is admitted through a conduit 31 and flows upwardly through an aperture 38 in a baffle 37 and through a screen 35.  A plurality of such units may be enclosed for parallel operation in a single vessel. Alternatively, a number of units may be used in series or in parallel-series.  In Fig. 4 the plate 77 of the electrode assembly is perforated to aid circulation of the atmosphere under the hood (not shown), and an additional screen 80 is placed closer to the discharge electrodes 70 than a screen 78, which is coarser than screen 78.  The action of the wind discharge on the water remaining in the region of the screen 80 is more severe thus accelerating coalescence and gravitation.  A potential of from 10,000 to 100,000 volts is specified for the electrodes which may be of tungsten or stainless steel.  The method is applicable to liquids other than water-in-oil emulsions.  Carbon dioxide, nitrogen, helium and argon are also specified for surrounding the electrode assembly.  Alternating current may be used to energize the electrodes but uni-directional current is preferred.

Patent GB-1015566-A (GB)
Title: Firing of lime and dolomite shapes
IPC: C04B35/06
Filed: 1964-08-24
Abstract: Burned refractory shapes are prepared from a refractory grain consisting essentially of MgO and at least 50% CaO (e.g. dead burred dolomite) by first heating to a temperature of at least 1000 DEG  F. in a moisture-free atmosphere at a slow rate (e.g. 200 DEG  F. per hour) to prevent hydration and cracking of the shape.  The heated shapes are subjected to a second firing to a temperature of at least 2700 DEG  F. for 48 to 100 hours.  The shapes must not be in contact throughout the process.  They may be separated by sanding with a particulate material which is physically inert to the firing and chemically inert to the shapes (e.g. dead burred periclase). Hydration of the grain may be prevented during formation of the shapes by maintaining a temperature of at least 212 DEG  F.  A non-aqueous binder (e.g. pitch or tar) may be used in forming the shapes prior to firing.  The shapes may be coated with a water repellent material after firing.  The firing may take palce in kilns and the shapes may be conveyed to the kilns on movable kiln cars.  In a review of the prior art a number of British and U.S. Specifications are referred to.

Title: Improvements in or relating to bladed rotor structures for turbines and compressors
Inventor: KROON REINOUT P
IPC: F01D5/30
Filed: 1959-10-13
Abstract: 868,903. Mounting turbine and compressor rotor blades. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 13,1959, No. 34622/59. Class 110 (3). A rotor for compressors, or turbines comprises a disc with a recess in its rim portion, a blade having a root portion received in the recess and means for attaching the blade to the rim portion including a tapered pin received in the rim portion with its axis parallel to the rotor axis, extending through the root portion and loosely received in a correspondingly tapered bore in the root portion. The centrifugal forces acting on the blade are effective to urge it transversely against the side of the recess to promote vibration damping of the blade. As shown, the rim portion 14 of the rotor disc 11 has a recess formed as an annular groove 15 into which are loosely fitted blades 12 with root portions 21 of parallelepiped form and of slightly less width and depth than the groove 15. The blade root is secured to the disc by a tapered pin 25 which is locked to the rotor by a nut 30, for example. The pin passes with some clearance through a frusto conical core 26 of equal taper in the blade root 21. This arrangement permits the blade 12 to move along and rotate about the longitudinal axis of the pin, the extent of rotation being limited by the clearance a between the blade platform 20 and rim portion 14. Thus, when under the influence of centrifugal force while the rotor is rotating, as the blade rotates with the disc 11 it is urged transversely along the pin 25 towards the apex of its conical surface until the root face 22 abuts against the side 17 of the groove such that effective damping of vibration is achieved. A cone angle a may be from 3 to 7 degrees. To increase the moment arm of the frictional force acting on the blade root 21 an annular recess 32 may be machined in the axial face 22 of the blade root 21.
