IPC: C10G31/06
Filed: 1948-04-15
Abstract: Complexes are formed by contacting a mixture of organic compounds with urea or thiourea, and recycling part of the separated complexes to the remaining mixture.  The process effects the separation of straight-chain compounds by complex formation with urea, or of branched-chain compounds by complex formation with thiourea. Diluents or solvents may be added to the reaction mixture and a saturated alcoholic solution of thiourea is mentioned.  The complexes may be fractionated and selected fractions recycled or alternatively they may be decomposed and a selected fraction of the regenerated organic compound recycled, to enrich the feed in a particular type of compound.  Normal compounds which form complexes with urea are listed in Specification 671,456 and branched-chain compounds forming complexes with thiourea in Specification 650,571.  Complexes containing varying proportions of urea may be formed by varying the conditions of reaction.  The complexes may be separated, as by filtration, and the organic compounds regenerated as described in Specification 671,456 (except that distillation of the complex with hot gases is not mentioned).  The process may be particularly applied to the separation of hydrocarbon mixtures and may be used in separating the products of alkylation, cyclization and isomerization processes.  Specifications 671,457 and 671,458 also are referred to.ALSO:Oils are refined by treating with urea or thiourea to form complexes with at least part of the oil, and recycling part of the separated complexes to the remaining mixture.  The process effects the separation of straight chain hydrocarbons (forming complexes with urea, inert to thiourea) from branchel chain hydrocarbons (forming complexes with thiourea, inert to urea). Diluents or solvents may be added to the reaction mixture, and a saturated alcoholic solution of thiourea is mentioned.  The complexes may be fractionated and selected fractions recycled or alternatively they may be decomposed and a selected fraction of the regenerated hydrocarbon recycled, to enrich the feed oil in a particular type of hydrocarbon.  The complexes may be separated, as by filtration, and the hydrocarbons regenerated as described in Specification 671,456, (except that distillation of the complex with hot gases is not mentioned).  The process may be applied to hydrocarbons which have been alkylated, cyclized or isomerized and may also be used to obtain high octane gasoline, high Diesel index fuel, and I.C. engine fuels of narrow boiling range.

Abstract: 578,029. Aerial masts. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and AINSLEY, F. J. June 9, 1944, No. 11084. [Class 40 (v)] [Also in Groups I and X] A mast assembly includes the mast 1 itself, provided with a foot member 2 (Fig. 1), and a base-plate 6, a spigot 5 centrally supported on the base-plate against lateral movement disposed between the foot member 2 and the baseplate 6 and at least one centrally apertured washer 4 of wedge - shaped cross - section mounted on the spigot, the arrangement being such that by rotation of the washer or washers 4, the angle which the mast makes with the base-plate may be adjusted. In the example described there are two washers 4, 4<1>, relative rotation of which enables the mast to be adjusted into a vertical position when being erected upon uneven ground. The base-plate 6 rests upon a tubular cross-piece 7 which receives base-tubes 10 and rests upon a locating plate 28. The foot member 2 whose top surface is sloped outwards to run off rain water, is of insulating material and is spaced from the wedge-shaped washers 4, 4<1> by a plate washer 23 and a lead washer 24. A bolt ring 12 is spaced from the foot member 2 by a lead washer 25 and is tightened down on the latter by the nuts of four bolts 8. The lowest of the four sections of the mast is received in an insulator bush 3 and the joints between sections are of tapered socket form with collars 29, 30 slightly spaced away from the joint to co-operate with a parting tool when taking down the mast. The stay pegs 11 which according to the Provisional Specification also form the earth connection are electrically bonded at 17 to the tubes 10 and the mast sections are bonded to each other at 14. In carrying out the levelling adjustment, keying marks k (Fig. 10), situated at the thickest and thinnest portion of each of the washers 4, 4<1> are brought together, thus making the outer horizontal surfaces of the pair of washers parallel. The washers are then rotated together in the same direction, keeping the marks k coincident until the horizontal projection of the inclined mast is at right angles to the line joining the two pairs of marks k. The washers are then rotated by equal amounts in opposite directions until the mast is truly vertical. Rotation of the washers 4, 4<1> is effected by means of towing bars engaging the recesses rc, rd. The mast may be one of four forming a directional wireless aerial system (Fig. 9) having stay wires 15 and a vertical sense aerial 16. When erecting the system, the four corners of the square locating the positions of the masts are set out by means of a triangular chain arrangement. The masts are then erected by hand using the tubes 10 as levers, the stay wires 15 and sense aerial 16 being secured previously to the masts.

Title: Improvements relating to clutches for drilling machines
IPC: B23Q5/04
Filed: 1931-04-16
Abstract: 375,007. Friction ratchet clutches. ARCHDALE & CO., Ltd., J. and JEWSBURY, J., Ledsam Street, Birmingham. April 16, 1931, No. 11253. [Class 80 (ii).] A multiplate friction clutch for drilling machines has a pressure plate in screw-threaded connection with a member carrying some of the plates, and a spring, weight, or fluid operated device, acts on a lever controlling the pressure plate to hold the latter in its operative position. As shown a pressure plate g is screwed to a hollow shaft e which is driven by a pulley f and has clutch plates c. The coacting clutch plates b are carried by a member a secured to a toothed wheel u driving a shaft w. A rod i passing through the shaft e carries a pin j which extends through a helical slot k in the shaft e and is fixed to the plate g. The outer end of the rod i has a thrust bearing l carried by a member m screwed to a fixed member n. The member m has a handle p having a projection q with which a spring- urged catch r engages. A second rod i<1> screwed to the rod i is associated with a pressure plate g<1>, a clutch a<1> and toothed wheel u<1>, for reverse driving of the shaft w. The projection q has inclined side faces. Movement of the handle p so that the catch r engages one of the side faces of the projection q causes the pressure plate to engage the clutch plates b, c, the spring-t of the catch r tending to exert a slight pressure to hold the clutch in operation. Engagement of the catch with the other inclined face of the projection q engages the clutch a<1> and drives the shaft w in the reverse direction. In a modification the pressure plate g, Fig. 3, is operated by a pivoted lever p and a catch r when the clutch is in operation tends to hold the lever p in the operative position. In another modification the lever p is operated by a fluid controlled piston.
