Title: Process of purification of naphthenic acids and naphthenic soaps and products obtained thereby
Inventor: ERBE FRIEDRICH
IPC: C11D15/00
Filed: 1952-05-30
Abstract: Naphthenic acid materials are purified by forming soaps from the naphthenic acids, mixing the naphthenic soaps in the presence of water with a low-boiling oxygen-containing organic compound miscible with water, removing the separated foreign matter, and, if desired, recovering the oxygen-containing compound from the aqueous solution of naphthenic soaps which solution may finally be acidified.  The "low-boiling" compounds have a boiling-point below or not considerably above that of water.  In the examples: (a) crude naphthenic acid is neutralized with caustic soda and the mixture is dissolved in water; methanol is added and the clear naphthenate solution is separated; the methanol is distilled off and naphthenic acid is obtained by acidification of the naphthenate with sulphuric acid; and (b) crude naphthenic acid is purified as in (a) using (i) dioxane instead of methyl alcohol as solvent and (ii) acetone as solvent.

Abstract: 970,180. Endless conveyers. THOMAS HUNTER Ltd. Feb. 28, 1963 [April 10, 1962], No. 13881/62. Heading B8A. Jars 3 arriving on conveyer 4 are located in respective recesses 11 of an endless belt 10 by the action of a surface 8 which is either stationary or is formed by an endless belt moving at a slower speed than the belt 10. Thus, each jaw, if it engages the belt 10 at a location not corresponding with a recess 11, is rotated and travels at a slower linear speed than that of the belt 10 until it engages the next recess 11. The surface 8 is spring urged by members 14 in the direction of the belt 10. The surface 8 may alternatively be made of a pad of foamed material or may be formed by an inflated tube. In a modification (Figs. 3, 4, not shown), the recesses 11 are deeper and closer together, and the jaws travel on a deadplate instead of the conveyer 4.
Patent GB-138857-A (GB)
Abstract: 138,857. Automatic Telephone Manufacturing Co., (Assignees of Jacobsen, E.). Feb. 12, 1919, [Convention date]. Automatic exchange systems ; coin-freed systems.-In a system in which conversation is rendered impossible from the moment when the called party answers until the calling party inserts a coin in his apparatus, a set of relays for controlling the speaking circuit for this purpose is associated with an exchange trunk common to a group of subscribers, and is operated by a special current from the calling sub-station, for example, by a momentary reduction of the line current. A calling line A is connected by a line switch C to a connector, which completes the connexion in known manner. The upper winding of a relay 18 is included in one side of the connector trunk, but this relay is constructed to respond only when both its windings act in agreement, and is not energized at the present stage, since the lower winding, which receives current from the test circuit, is in opposition. When the called party replies, the current in the calling line is reversed in known manner, energizing relay 18, which disconnects the lower side of the calling line from the called line and connects it through relays 45, 46 to a coil 47, so that the calling party gets a signal from the dewice M<1> to deposit a coin. As the coin passes down the shoot 51 it momentarily opens a contact 53, so as to cut a resistance 52 into the line circuit. This has the effect of de-energizing relay 45, but not relay 46, so that a circuit is closed for relay 50, which locks itself up and short-circuits the upper winding of relay 18, which relapses and completes the talking circuit. In a modification, it is necessary to deposit a coin before transmitting the number impulses, so as to open a contact which short-circuits the impulse transmitter. In the case of successful calls, the subscriber operates a catch to pass the coin into a collecting shoot, where it operates a contact as shown in Fig. 1, but in the case of unsuccessful calls the coin is passed into a return shoot when the receiver is hung up.
