Title: Improved process for obtaining high boiling organic acids from their mixtures with high boiling oils
IPC: C07C51/44
Filed: 1928-07-30
Abstract: 294,892. Standard Oil Development Co., (Assignees of Coleman, S. P.). July 30, 1927, [Convention date]. Mineral oils, purifying.-Mineral oils which contain naturally occurring or artificially produced acids are treated with alkali to convert the acids to salts, the oil is distilled off, and the acids are recovered from the salt residue. In an example, for the production of naphthenic acids from Gulf coast oil, the crude oil or an oil distillate, which may have been treated with acid, is passed from a tank 1 to an agitator 4 having a steam-jacket 4<a> in which it is treated with alkali solution and agitated with air. The oily layer is withdrawn by a swing-pipe 9 to a tank 8, and the aqueous layer is treated with sulphuric and other mineral acid which causes the organic acids and remaining oil to separate from the aqueous liquor. The aqueous liquor is discharged by a pipe 13, and caustic soda solution is added to combine with the organic acids, the mixture being blown dry by warm air from a pipe 5. Gas oil is added and the hot homogeneous mixture is taken to a tank 15 from which it passes to a heading-coil 18 to which steam may be admitted by a pipe 19 to increase the rate of flow. The mixture is heated rapidly to above 700‹ F, and is discharged into a vaporizing drum 20 which is preferably maintained under high vacuum. The vapour passes to a condenser 22 and the condensed soil collects in a drum 23 from which it goes to a tank 32. The soda-salts which remain in the drum 20 are run into water in a tank 27, and treated with mineral acid in a tank 29, the separated organic acids being collected in a tank 31.

Title: Printing telegraph apparatus for transmitting teleprinter signals with increased reliability
IPC: H03M13/51
Filed: 1958-07-11
Abstract: 831,417. Type-printing telegraphy. CREED & CO. Ltd. July 11, 1958 [July 17, 1957], No. 22392/58. Class 40 (3). In a teleprinter for the transmission of unprotected signals, i.e. normal operation, and in which some signals are protected in transmission by using code combinations having a predetermined number, or numbers, of marking elements with the teleprinter in a third or additional case-shift condition, the line-feed signal is used, in addition to its normal function, for the purpose of permitting the teleprinter to be operated solely for error-protected transmission, and the carriage-return signal is employed, in addition to its normal function, to permit the teleprinter to function in the normal manner, with the exclusion of the error-protected transmission. In the arrangement described, the numerals are transmitted with the teleprinter in a third case-shift condition by 5-unit code combinations having three marking elements, and the signs +, - as code combinations with only one marking element, the three remaining signals of this category, indicated by an asterisk in Fig. 2, being employed, in normal teleprinter operation, for space, line-feed and carriage-return, and being necessary in the protected transmission. The operation of the linefeed signal key lever allows the operation of the key CS for the third case-shift and, in addition, all the key levers of the top row of keys, whilst it also operates a locking-bar to lock all the other key levers. At the end of a period of protected transmission or at the end of a line, the carriage return and line-feed signals are transmitted, and if unprotected transmission is to ensue, the carriage-return key is again operated, and this is effective to lock the keys of the top row, with the exception of those for the numerals 2, 6, 7 which in the usual teleprinter code are represented by combinations with three marking elements. The protected characters printed from a third row of type or case-shift position, e.g. a third row on a type-wheel, are printed in italics as indicated by Fig. 3 (not shown), and character positions or type levers not associated with the protected characters effect, if selected by faulty transmission, the printing of an error symbol. In a modification, a locking device prevents the printing of the symbol for mutilated signals in response to an all spacing signal if the carriage is at the beginning of a line, and in a further modification, a device is provided to prevent continuous printing of the error symbol in response to a prolonged spacing signal indicating a break in the transmission line. Specification 818,770 is referred to.

Roller-and-breast mills.-In a grinding mill for paints &c. and/or of the kind in which the material is ground between a grinding bar c, Fig. 2, and roll a, one or a number of scraping devices e is disposed in close proximity to the grinding bar for the purpose of preventing an accumulaton of material in front of the grinding bar and/or of cleaning the surface of the grinding roll during its operation. The scraper e is guided on a rod g and is provided with a collar j surrounding a rod h screwed with a right and left hand thread. A double-ended pawl k, Fig. 1, weighted at l is pivoted to the rod e and one or other of the pawls k engages in the threads on the rod h. The rod h is driven by sprocket wheels and chain from the rod n; projections o are formed in the hopper b such that when the scraper reaches the end of its travel the weight o strikes the projection and is tilted so that the other pawl engages in the other thread on the rod h and the direction of motion of the scraper is reversed. In a modification, Fig. 4, scrapers p are attached to a rod q adapted to be reciprocated by a lever t connected to an arm or arms 5 pivotally mounted at one end and reciprocated by an eccentric rod 4 driven from the shaft y by worm z and wormwheel 2. The arm or arms 5 also reciprocate the roller a. In a small type of mill a grinding roll shaft which is reciprocated by the usual cam arrangements may carry a collar to which pivoted links are connected which operate the scraper rod from their upper ends.
