Title: A process for the manufacture of alcohols from olefines
IPC: C07C29/06
Filed: 1933-06-26
Abstract: In the production of alcohols by treating olefines such as those from the cracking of mineral oils, with sulphuric acid, polymers are removed from the absorption product (which may be first hydrolyzed) by extraction with solvents of low boiling-point such as benzene, toluene, xylene, carbon tetrachloride, ethylene chloride, trichlorethylene, benzine fractions having high aromatic content such as benzine fractions derived from Borneo oils, also cyclohexane and isopropyl acetate.  The solvents are also used as entraining agents in the azeotropic distillation of the dilute alcoholic distillate. The extraction treatment is preferably applied to the hydrolyzed alkyl sulphuric acid, and, where losses of alcohol are liable to occur, the extraction may be effected in the manner described in Specification 355,294, [Group III], water or dilute sulphuric acid being used as second washing liquid.  In an example, propylene is absorbed in 96 per cent sulphuric acid at 0--10 DEG  C. and the product is diluted and hydrolyzed, the hydrolyzed product being washed with water and benzene.  The purified solution is then distilled yielding an alcohol of 79,2 per cent and residual sulphuric acid of about 30 per cent.

Abstract: 1,031,400. Change-speed control. FORD MOTOR CO. Ltd. April 30, 1965, No. 18219/65. Heading F2D.  A gear-change mechanism comprises a rotating and reciprocating shift-rod on which a series of shift-forks are slidably mounted, the rod being rotated to select a gear ratio and reciprocated to establish the ratio. In the arrangement shown the shift rod carries three aligned radial pins 31, 33, 35 and three U-shaped shift forks 15, 16, 17 arranged in tandem, the forks having shaped cut-outs with recesses 37, 39, 41 engageable by the pins upon rotation of the shaft. As shown, pin 31 engages recess 37 of fork 15 for selecting third or fourth gear, and upon rotating the shaft in one direction pin 33 engages recess 39 of fork 16 for first or second gear, while rotation in the opposite direction causes pin 35 to engage recess 41 of fork 17 for reverse. An interlock mechanism consists of a pivoted single arm member 45 carrying a double arm member 49, the ends of the respective members having rounded projections 47, 51 engageable with recesses 43 in the sides of the shift-forks. The arrangement is such that when a fork is moved to engage a gear the associated projection is disengaged from the recess 43 in the fork while the other two projections are held in the recesses in the two inoperative forks to prevent their movement. A ball detent is provided to lock the shift rod in its adjusted axial position. In a second arrangement, Figs. 5-10 (not shown), the shift forks are nested within one another and are operated by a single radial pin on the shift rod.

A high-speed spindle 5, particularly for use in spinning machinery, is mounted in a ball, or as shown, a roller bearing 3 and a step bearing 7, both supported in a sleeve 1 which is welded to a part-spherical boss 2 resting in a casing, not shown. Lubricant fills the lower section of the casing and also the clearance space between the sleeve 1 and the spindle 5, the sleeve 1 having an axial slot 36. Rotation of the spindle 5 carries the oil round with it, and the slot 36 presenting an opposing edge to this movement of the oil, local turbulence is set up which generates an oil mist; this oil mist lubricates the bearing 3. In modified forms of the invention, the slot 36 is replaced by an axial groove, by an axial rib in a solid sleeve, by individual bosses, projections or depressions spaced out over the inner surface, by an open tube as shown in Fig. 4, and by other like means. A shrunk-on ring 9 holds damping- means 13, 4 to the slotted bearing sleeve 1. An axial slot 46 may be provided in the damping-means 13. The width of the slot 36 may be adjusted to vary the quantity of oil mist produced; in particular, the slot may be narrower at the top than at the bottom. The neck bearing 3 may be provided with means to store excess lubricant which is thrown out, and return it when the spindle is at rest; these means also form a seal to prevent oil mist escaping. In Fig. 5, such a device comprises a non-removable cover 8 having a cavity 12 to store oil. In one modification, Fig. 7 (not shown), a removable cover is described which can be filled with grease to lubricate the bearing 3 during the starting period, and in a further modification, Fig. 8, also (not shown), a labyrinth type of packing is disclosed.
