Patent ES-271526-A1 (ES)
Title: Improvements in or relating to substituted indoles
IPC: C07D209/42
Filed: 1961-10-26
Abstract: The invention comprises compounds having the general formula <FORM:0938903/IV(a)/1> wherein R represents an alkyl radical containing 1 to 4 carbon atoms, or an aralkyl radical containing 7 to 10 carbon atoms, and R1 represents an alkyl radical containing 1 to 4 carbon atoms, or a benzyl radical. The invention also comprises a process for preparing the compounds of formula I wherein a compound of general formula <FORM:0938903/IV(a)/2> is decarboxylated, and a process for preparing the compounds of formula Ia wherein a compound of formula I is alkylated with an alkylating agent containing 1 to 4 carbon atoms or benzylated with a benzyl halide. The indole-2-carboxylic acids mentioned above can be prepared from an appropriate 2-nitro-6-alkyl (or aralkyl) thio-toluene in the following manner:-the substituted toluene is condensed with a dialkyl oxalate in the presence of an alkali metal alcoholate to form an alkali metal enolate derivative of a substituted phenylpyruvic ester which is saponified to the corresponding phenylpyruvic acid whereupon the required indole-2-carboxylic acid compound is obtained by cyclising in the presence of sodium dithionite (Na2S2O4) or ferrous hydroxide. Alternatively, in the above process, the phenylpyruvic ester enolate may first be cyclised and then saponified to yield the required indole -2-carboxylic acid. The substituted toluenes used as starting material can be obtained by diazotising 2-nitro-6-amino-toluene, and reacting the product with an appropriate mercaptan. In Example 1, 2-nitro-6-amino-toluene is diazotised, and then reacted with methyl mercaptan in the presence of copper bronze giving 2-nitro-6-methylthio-toluene which after treatment with diethyl oxalate and potassium ethylate in ether, and subsequent saponification yields (2-nitro-6-methylthio-phenyl-pyruvic acid on acidification. The product when treated with sodium dithionite and sodium hydroxide, and then acidified yields 4-methylthio-indole-2-carboxylic acid which heated under reduced pressure at 260-270 DEG C. and then distilled gives 4-methylthio-indole. In Example 2, 4-benzylthio-indole is obtained by treating diazotised 2-nitro-6-amino-toluene with benzyl mercaptan, and then proceeding in a manner analogous to that described in Example 1. 1-Methyl-4-benzylthio-indole is obtained by treating 4-benzylthio-indole with methyl iodide and potassium amide 1-benzyl-4-benzylthio-indole is similarly obtained using benzyl bromide instead of methyl iodide. The 4-alkylthio (or aralkylthio)-indoles may be used as odoriferous substances, as intermediates in the production of indole compounds, and for attracting or repelling insects.

Patent ES-362921-A1 (ES)
Title: Process and device for the automatic continuous injection of an adjuvant into a fluid
IPC: B01J4/00
Filed: 1969-01-25
Abstract: In a device for the automatic injection of a fluid adjuvant supplied from a resevoir 13 into a stream of a different fluid contained in a channel 15 the pressure in the cylinder 1 or 2 about to commence discharge is increased so as to be greater than or equal to the pressure of the discharge of the other piston. In one embodiment as shown in Fig. 1 as the piston 4 is completing its discharge stroke the piston 3 has already begun its discharge stroke before actual injection from the cylinder 1 occurs. In operation, while the piston 4 is on its descent it triggers the contact 24 to start the descent of the piston 3 which builds up pressure until the constant pressure device 17 triggers the relay 18 to simultaneously change over the value 11, stop and reserve the motor controlling piston 4 and open the valve 27. A simular set of operations occur when the piston 3 is on the descent thus completing the cycle, and hence no interruption or variation in pressure takes place in the injection of the adjuvant. In a modification Fig. 2 (not shown) a common reversible motor (30) with a speed variator (31) is provided to move the pistons (40), (41) simultaneously and in opposite direction and a nitrogen feed (36) is connected to the feed line 14 to establish the desired pressure in the cylinders 1, 2 before the injection phase. A three way valve (37) replaces the valve 27 to allow the channel 14 to be fed either by adjuvant or nitrogen.
Patent ES-364110-A1 (ES)
Title: Improvements in or relating to centrally controlled exchange systems
IPC: H04Q3/545
Filed: 1969-02-26
Abstract: Scanning for line conditions proceeds over subscribers' line circuit groups (such as TG1) and other exchange circuits (such as own and other exchange relay sets HUe and AUe, and operators' relay sets VPl), each group of line circuits and each other exchange circuit having an associated row of a scanning matrix store SpMa, one element of each row indicating the state of the group of line circuits or the state of the other exchange circuit, a row scanner AE1 examining the state elements of each row of the matrix in synchronism with a scan of the corresponding line circuit groups and other circuits, a column scanner AE2 automatically ensuring that the columns containing the state elements are selected during such scanning. The matrix SpMa may consist of a number of planes so as to provide a multi-bit storage capacity for each element of the matrix ferrite cores being employed as storage elements. The line circuit groups TG have a common intermediate store TZS, comprised of ferrite cores, on which is set up in parallel the states of the individual subscriber lines. An OR-function establishes a group state if any one or more of the lines is in the active state. The corresponding scanning matrix row has an element for each line of the group and an additional element, in column n, to indicate the group state, as last scanned. The first column of each row corresponding to another exchange circuit (Hlle Alle, VPl) records the circuit state. For each scanning position of the row scanner AE1 the state data from the last scan as recorded in the matrix is read out to register ZR2 while the corresponding current data from the circuits themselves is recorded in the register ZR1. A logic circuit ZO determines from a comparison of current and last look data what, if any, action is required by the central control circuit ZeSt, such action being implemented and the matrix store brought up to date before the scanner proceeds to the next row. If the group state data indicates activity requiring attention in a line circuit group, the scanner Ae2 steps over the elements of the intermediate store TZS and the corresponding elements in the associated matrix row so that the states of the individual lines are compared with the last look data in ZO with ZeSt reacting accordingly. The scanner Ae2 has a section 5 said to be employed for route finding.
