Filed: 1957-05-28
Abstract: 867,205. Titanium carbide. UNION CARBIDE CORPORATION. May 28, 1957 [June 19, 1956], No. 2002/61. Divided out of 867,204. Class 1(2). Titanium carbide is produced by heating an intimate mixture of titaniferous ore, e.g. Ilmenite, Perovskite, or Sorel slag, coke, sawdust, and water in an Acheson-type resistance furnace to a temperature of at least 1500‹C. In the Acheson-type furnace heating is effected by passage of an electric current through a central core of carbon extending between two electrodes, the charge being packed around the central core. Sufficient coke is employed to effect conversion of all the titanium of the ore into carbide. The sawdust is added for porosity and the water for gas permeability. Examples are given.

Title: A method and apparatus for refining vegetable and animal oils
IPC: C11B3/06
Filed: 1949-01-27
Abstract: <PICT:0670971/III/1> <PICT:0670971/III/2> In the continuous refining of fatty oils with lye wherein the lye is intermixed in the oil in the form of fine droplets, the neutralizing of the oil globules and the agglomeration of the formed soap is completed in a chamber without substantial agitation and without substantial atomizing of the droplets, and the soap is removed from the oil by centrifuging in a centrifugal separator, the centrifugal separator is of the type in which the rotating parts are entirely filled with liquid.  The process reduces the amount of emulsified oil in the soap resulting from the more usual processes employing agitation of the mixed liquids. The oil and lye may be preheated before mixing or the mixture is heated between the reaction vessel and the centrifugal separator so as to aid the agglomeration of the soap drops.  The centrifugal separator is of the hermetic type in which the bowl is entirely filled with liquid since with such separators the liquid is fed thereto without shock.  In a suitable plant, the mixer consists of a rapidly rotating wheel A enclosed in a housing having inlet nozzles B and C, for the oil and lye respectively, arranged to direct jets of the liquids against the surface of the wheel so as to divide the lye into droplets which are suspended in the oil.  The liquid mixture is then discharged through an outlet F to the reaction chamber D, in which substantial agitation is avoided, and from thence to the centrifugal separator E of the above type.  The refining of coprah oil is exemplified.  Specification 417,996 is referred to.

The nut passes freely over the screw 4, in the position shown on the upper part of the Figure; till the edge of the lug 2 contacts the nick 5, the nut then tilts into engagement with the thread and a part turn effects tightening. In another form the nut is bent to a segment of a cylinder 6, Fig. 4, and the hole is offset from the centre giving the effect of unequal legs. The sheet metal may be otherwise folded to produce unequal legs. The nut may be a section of a cylinder with a thin internal flange 13 and one face inclined to the axis. The cylinder may be of plastic material with a thin sheet metal insert to form the flange. A flat sheet metal nut may have a transverse screw on one side to take the place of the lug 2.

A valve comprises a valve closure member in the form of a hollow cylinder which is guided in a passageway in axial alignment with an inlet passage, the valve closure being movable axial into and out of seating or overlapping engagement with the end of the inlet passage. The interior of the valve member is in constant communication with the inlet and when the valve opens, part of the fluid flows into the cylinder, undergoes a change in direction of substantially 180 degrees and flows into the outlet at an angle to the direction of movement of the valve closure while part of the fluid flows direct to the outlet. In Fig. 3, the valve closure member 3 enters the inlet 4 to close the valve and the open sides of the valve member are tapered. The upper end of the valve member may be closed or may be provided with a port 1 allowing flow through the valve. In Fig. 4, the valve member 16 overlaps the inlet passage 17. In a modification, the inside of the inlet passage and the outside of the closure member are tapered. In a further modification, a valve member similar to 16 moves into the inlet passage and the fluid flows to a groove which alters the flow forces.
