Title: Process for the Production of Alcohols from Olefins
IPC: B01J27/16
Filed: 1966-07-22
Abstract: 1,159,667. Hydration of olefins. HIBERNIA CHEMIE G.m.b.H. 22 July, 1966 [24 July, 1966], No. 12313/69. Divided out of 1,159,666. Heading C2C. In a continuous process for the hydration of C 2-6  mono-olefins to alcohols, olefin and water are fed to an exchange zone and then to a superheating zone at an elevated temperature and pressure, the heated reactants are passed to a hydration zone containing an acid catalyst supported on a porous carrier, the gas or gasliquid mixture is withdrawn from the hydration zone and conducted to the heat exchange zone to condense an alcohol-containing liquid, which is passed to a collecting zone, and leaving an alcohol-containing gas which is passed to a cooling zone from which the cooled gas is conducted to a washing zone at an elevated temperature and pressure, wherein the gas is washed with water to leave an olefin-containing gas, which is recycled to the hydration zone after make-up with olefin and water, and an alcohol containing liquid which is conducted to a collecting zone. It is preferred to effect hydration at 140-250‹ C. under a pressure of 10-100 atmospheres over a phosphoric acid catalyst. The alcohol may be recovered by distillation of the aqueous product. Examples relate to the preparation of isopropanol from propylene.

Patent GB-400967-A (GB)
Title: Improvements in or relating to calculating machines
IPC: G06C21/04
Filed: 1932-05-03
Abstract: 400,967. Calculating-machines. BURROUGHS ADDING MACHINE CO., 2nd Avenue, Detroit, Michigan, U.S.A.- (Assignees of Racz, E.; 3709, Richton Street, Detroit, Michigan, U.S.A.) May 3, 1932, No. 12779. Convention date, May 4 1931. [Class 106 (i).] A calculating-machine adapted to print the items, including characteristic symbols denoting for example departments, cannot be operated unless such symbol has been set up, a connection between the driving-means and the driven mechanism of the machine being disabled. In a modification the total or sub-total cannot be taken unless the symbol-setting has been performed. The invention is described as applied to the known Burroughs Portable machine. The driving shaft 11 is adapted through a fast arm 40 to drive the full-stroke sector 45 and the other operating-mechanisms of the machine by engaging a pawl 43 pivoted to the sector at 44. If the setting of the keyboard is not in accordance with the prescribed conditions this pawl is disabled by engagement with a lug 46 on a lever 35 so that the drive is ineffective. When a department key 20 is set a slide 22 rocks a bail 27 clockwise, Fig. 1, and therefore a bell crank 32 counterclockwise so as to remove obstruction from the lever 35. As the machine commences to operate a slide 50, Fig. 4, moves rearwardly to allow a cross-rod 52 to follow suit and through a supporting arm 58 to rock the lever 35 to allow the pawl 43 to function. If the proprietor desires to remove this control by the keys 20 he inserts a key 86, Fig. 4, and turns it so as first to free a slide 85 from tumbler plates and then to shift it to the rear so as to rock the bail 27 in the same way as depression of a kev rocks it. The slide 85 is locked in either of its positions and its position thus determines the efficacy or otherwise of the department key control. The department key control may be disabled, when a total or subtotal is taken, by means of a slide 71 moved forward by depression of either key so as to rock the bail 27 and thus permit the operating- mechanism to be driven. In the modification, shown in Fig. 9, the total or sub-total key, T or ST, when depressed rocks a lever 104 downwardly, thus tending to carry a pawl 106 below a pin 110 on the slide 50. If no department key is depressed the end 112 of a pitman 113 connected to the bail 27 prevents descent of the pawl so that the slide cannot shift and consequently the machine drive is disabled. The depression of a department key, however, removes the obstructing end 112 and allows the machine to function.

Title: Improvements in and relating to chlorinated methylpolysiloxane resins
Filed: 1946-05-02
Abstract: Chlorine is passed at reflux temperature into a solution in an inert solvent, e.g. carbon tetrachloride, of a methylpolysiloxane resin having a methyl-to-silicon ratio between 1 and 2 until the chlorine-to-methyl ratio of the resin is between 0.2 and 0.4. Cured films of the chlorinated resins are non-flexible, tougher and more craze-resistant.  Preferably the reaction mass is irradiated with ultra-violet light during chlorination.  Suitable resins for starting materials as described in Specifications 542,655 and 572,230.  In example 1, a methyl siloxane resin from dimethyldichlorosilane, methyltrichlorosilane and silicontetrachloride with a methyl-silicon ratio of 1.4 was dissolved in carbon tetrachloride and exposed to the radiation of a mercury quartz lamp.  Chlorine was passed through the solution, the heat of reaction maintaining refluxing temperature. When the chlorine-methyl ratio was 0.2 the solvent was evaporated and glass fibre tape was impregnated with the chlorinated resin and dried and cured.  Comparison was made with glass fibre tape impregnated with unchlorinated resin.  Examples 2, 3 are similar.  The chlorinated resins exhibited better curing properties with ferric chloride or aluminium chloride than the unchlorinated resins. Specification 585,628 also is referred to.
