Patent GB-201986-A (GB)
Title: Improvements in the refining of mineral oil
IPC: C10G73/06
Filed: 1922-05-01
Abstract: Wax is removed from the heavy lubricating oil fraction, obtained when crude petroleum is fractionally distilled by fire and steam to avoid substantial cracking, by precipitating the wax while maintaining the oil fluid, and centrifuging so as to discharge the oil and wax separately.  Any light lubricating oil accidentally passed over with the heavy oil fraction may be removed by distillation prior to the precipitation of the wax.  In an example, "34 stock" is distilled to remove light lubricating oil amounting to 35 per cent, the residue is diluted with 70 per cent of a lighter solvent, such as naphtha of 65 DEG  B<\>ae, and the mixture is chilled to -10 DEG  F. in apparatus in which the wax is constantly scraped from the chilling surface with as little agitation of the oil as possible.  The mixture is then centrifuged with a carrier liquid such as water or brine, as described in Specifications 119,288 and 157,688, [both in Class 23, Centrifugal machines &c.].  The light lubricating distillate is chilled and filter-pressed as usual.  When crude oil having an asphaltic base is fractioned, the residue remaining after the removal of the heavy lubricating-oil fraction is distilled with cracking to increase the yield of lubricating oil.  The invention p  is contrasted with those described in Specifications 166,031 and 197,389.  Reference has been directed by the Comptroller to Specification 166,031.

Abstract: 255,984. British Thomson-Houston Co., Ltd., and Dreghorn, H. May 16, 1925. Alternating-current commutator machines.- An alternating-current commutator motor is provided with a rotor and stator divided into two sections with a separate regulating commutating winding on each section, whereby only a part of the total main flux cuts the commutated coils, giving a reduced voltage per segment and a higher output per pole. In the form shown, the rotor of a variable-speed motor is formed in two sections 1, 2 embraced by a common primary coil 3 fed through slip-rings. Each section carries a regulating winding 6, 5 connected through commutators 8, 7 to secondary coils 12, 11 on the two-part stator. Each core carries half of the total flux so that the volts per segment on the commutators are one half of the value given in the usual arrangement. The brush sets are geared together, for instance by bevel gearing, so that the two sets move together and the two sections of the machine share the load equally. Resistance connections and short-pitch coils may be employed. In a modified form, both cores are embraced by a single secondary winding which is connected in series with both regulating windings. Or, alternatively, the primary and secondary windings embrace both cores and are used with only one regulating winding which is wound on a half or any other fraction of the total core length. In the case of a machine in which the commutator winding is used for power factor improvement, one set of commutator brushes only is employed.

[Also in Division B5] A method of taking samples of granular such as a mixture of iron ores material comprises the steps of continuously taking first samples of the material and pulverizing them, continuously taking second samples of the pulverized substance of the material derived from the first samples, pulverizing the second samples of the material and then extracting from the latter particles of the material which has attained a certain granular size. The material is fed on a belt conveyer 1 and falls on to an exit conveyer 2, a certain portion being directed by means of a shoot 3 and funnel 4 on to a belt (5, Fig. 1) leading to a roller crusher (6). The pulverized material then falls on to a conveyer 7 from which a portion of the material falls through a shoot 8 on to a belt 9, the remainder falling on to a conveyer 9a leading to the exit conveyer 2. The portion of the material on the belt 9 is again split up into a further portion by means of a shoot 10 leading to conveyors (11,12, Figs. 4 and 5). From the conveyer (12) the pulverized sample is fed into a crushing mill (15) the outlet of which being connected to a pneumatic selector (17) adapted to separate particles of a certain size and allow them to be fed into a cyclone (23) by means of compressed air circulated through pipes (22, 24) by a pump (20). The outlet of the cyclone leads into a hopper (30) which is connected to a tablet making apparatus (see Division B5).
