Title: Improvements relating to the refining of crude wax obtained from mineral oil
IPC: C10G73/36
Filed: 1944-02-29
Abstract: Crude mineral wax is refined by bringing it to a temperature which is below its melting-point and is such that the mass contains liquid constituents separable by drainage, separating the latter from the solidified material in the mass, and thereafter subjecting the solidified material to sweating by heating it in a drainage vessel while allowing liquefied constituents to drain from the vessel.  The preliminary separation may be effected at a temperature, e.g. of 6 DEG  F. below the melting-point of the crude wax, either by cooling the liquefied crude wax or by heating the solidified crude wax.  This operation may be carried out in the drainage vessel or the material may be brought to the appropriate temperature outside the drainage vessel, the separation being effected therein, or as in the latter, but the separation being effected before the solidified material is charged into the drainage vessel.  By any of these methods the drainage vessel may be fully charged before the sweating <PICT:0605936/III/1> step.  A suitable plant using the first method comprises a drainage and sweating tank 4, provided with temperature regulating pipes 5, a filter 8 and a downwardly inclined base 9, a supply tank 1 and a receiving tank 13 connected to the drainage tank by piping 3 and 21, and a refined wax collecting tank 14.  The drainage tank may be housed in a temperature-controlled room.  In operation, the filter 8 is first sealed by filling the space between it and the bottom 9 with water, and the tank 4 is then filled with the liquefied crude wax.  Cooling fluid is passed through the pipes 5 and the air in the room brought to the same temperature; the filter is then unsealed and the mass allowed to filter, the liquid constituents being drained into the receiving tank 13.  A fresh charge is admitted to the tank and the process repeated until the tank is filled with solid wax.  The latter is then sweated by passing heating fluid through the pipes 5 and adjusting the air temperature correspondingly.  The liquid constituents are also drained into the tank 13 and the refined wax finally melted out by admission of steam for collection in the collecting tank 14.  In the second method external coolers are provided, the remainder of the plant and the method of working being as before.  In the third method a preferred cooling apparatus comprises a trough of U-shaped cross-section provided with a longitudinally extending rotatable shaft carrying radially arranged blades and the liquefied crude wax is subjected to a churning movement therein.  The separated solidified material is then introduced into the drainage vessel and subjected only to the sweating operation as described.

Abstract: 265,979. British Thomson-Houston , Co., Ltd., (Assignees of Prince, D. C.). Feb. 11, 1926, [Convention date]. Vapour apparatus, arrangement of; polyphase transformers.-In a conversion system in which an alternating current circuit 1 is connected to a direct current circuit 2 through a polyphase transformer 3 and mercury vapour device 4, the voltage relationship of the circuits 1, 2 is regulated by controlling the third harmonic of the fundamental voltage applied to the transformer. The third harmonic may be regulated by means of a tertiary winding 11, Fig. 1, connected in open delta to a winding 13 of a saturated core regulator in which saturation is varied by a series winding 14 in the direct current circuit. In an alternative arrangement an interphase transformer is utilized in conjunction with a saturated core regulator controlling the impedance of the tertiary winding 11, saturation of the regulator being differentially controlled by means of a manually regulated shunt winding and a series winding connected in series with the saturating winding of the interphase transformer. Specification 356,986 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the arrangement shown in Fig. 1 (Cancelled), in which the primary and secondary windings are arranged on a core 7 the outer limbs of which are provided with slots 10 so that the third harmonic is limited to a predetermined magnitude by limitation of the harmonic flux. This subject-matter does not appear in the Specification as accepted.

[Also in Group XXXIV] A hydromechanical variable-speed transmission for motor cars comprises a hydrodynamic torque converter having an engine-driven impeller i, a first turbine t<SP>1</SP> connected through a one-way clutch c<SP>1</SP> to a shaft 3 and a sun gear s<SP>1</SP>, a second turbine t<SP>2</SP> fast with a shaft 4 and a sun-gear s<SP>2</SP>, a single, or, as shown, two-part reactor r<SP>1</SP>, r<SP>2</SP> connected through one-way detents c to a reaction shaft 2, a third sun gear s<SP>3</SP> controlled by an hydraulically engaged brake 6, and interengaging compound planet pinions p<SP>1</SP>, p<SP>2</SP>; p<SP>3</SP>, p<SP>4</SP> mounted in a carrier 8 fast with a final driven shaft 7. When starting the car from rest, the brake 6 is applied to station the third sun-gear s<SP>3</SP>, and the first turbine t<SP>1</SP> transmits drive, the second turbine t<SP>2</SP> rotating more slowly. As the speed increases, the second turbine t<SP>2</SP> begins to drive, causing the first sun-gear s<SP>1</SP> to be rotated more quickly than its turbine t<SP>1</SP>, with the one-way clutch c<SP>1</SP> over-running. To obtain direct drive with the hydro-dynamic torque converter bypassed, fluid under pressure is supplied to act upon a piston 29 and engage a friction clutch 21 between a shaft 10, fast with the torque converter impeller i, and the output shaft 7. In the form shown, the two-part reactor element r<SP>1</SP>, r<SP>2</SP> acts through its one-way detents c to turn the reaction shaft 2 which has an arm 22 fast therewith, a spring 23 engaging the arm and opposing rotation of the shaft. As soon as no torque is applied through the reactors r<SP>1</SP>, r<SP>2</SP> upon the shaft 2, the arm 22 moves to open a valve 24 which disengages the hydraulically applied brake 6 and engages the hydraulically controlled clutch 21 for direct drive. To obtain reverse, an hydraulically controlled brake 9 is applied to station the shaft 4 and the sun-gear s<SP>2</SP>. In a modification, Fig. 2 (not shown), a hydrodynamic torque converter has three turbines, two of which are connected through one-way clutches to two sun-gears, a third is connected directly to a third sun-gear and a fourth sun-gear can be braked to act as a reaction member. An additional low ratio is obtained by braking an internally toothed annulus engaging the planet pinions p<SP>1</SP>. The direct drive clutch is an hydraulically controlled disc clutch located within the housing h of the hydrodynamic torque converter. In another modification, hydrodynamic braking when the car over-runs its engine is obtained by engaging an hydraulically-controlled friction disc clutch 25, Fig. 5, in parallel with the one-way clutch c<SP>1</SP> connecting the first turbine t<SP>1</SP> to its shaft 3.
