Examples are given. 1, 2, 3, 4-Tetrahydro-b -carboline-3-carboxylic acid alkyl esters are prepared by condensing tryptophenes with aldehydes and esterifying the acids produced or by esterifying trypophanes with alcohols and condensing the trypophane alkyl esters with aldehydes. The products may be dehydrogenated to give b -carboline-3-carboxylic acid alkyl esters. The esters on saponification give the corresponding acids. 3-Cyano-b -carbolines are prepared by halogenating b -carbolines and reacting the 3-halogeno-b -carboline products with metal cyanides. 3-Cyano-1, 2, 3, 4-tetrahydro-b -carbolines are prepared by converting indole-3-acetaldehydro by Strecker synthesis into a -amino-b -(indole-3)-propionitriles and then cyclizing these with aldehydes. 1-Methyl-3, 4-dehydro-b -carboline-3-carboxylic acid methyl ester is prepared from the free acid and methanol, and isolated as the hydrochloride, or from N-acetyl-tryptophane-methyl ester which is heated with phosphorus trichloride and then with ethanol and hydrochloric acid.
Patent ES-292028-A1 (ES)
Title: Coin-operated telephone
IPC: H04M17/02
Filed: 1963-09-27
Abstract: The cashing-in of coins at a pay-station causes electrical signals indicative of their value to be passed to a register at the station which sums the signals and thus records the amount cashed in, reception of impulses indicative of the charge for a call causing the number stored in the register to be reduced accordingly. When this number becomes zero, further cashing-in is effected. Coins not cashed-in are returned to the caller at the end of the call. The coin collecting means, the coin returning means, the register which computes the value of the unused cashed-in coins and means for interrupting the call if no further coins are available for cashing-in are all constituted by transistor circuits.

Title: Lubricated double-acting valve seat
IPC: F16K5/22
Filed: 1969-04-07
Abstract: A rotary ball valve has upstream and downstream seats 78 each urged by a spring 77 against the ball 34 and provided with a seal 84 received in a recess between the seat proper and a retainer 80. Each seal is provided with lubricant from a connection 94 via passages 92, groove 126, passages 128, and knurling (131) on the outer periphery of the retainer 80.

Title: Walking beam conveyor
IPC: C21D1/00
Filed: 1970-06-02
Abstract: A walking beam conveyor of the kind which comprises a series of stationary beams and a series of walking beams which have a driving mechanism by which they are moved upwards relative to the stationary beams to lift workpieces therefrom, then longitudinally to convey the workpieces along the stationary beams and subsequently downwards again to replace the workpieces on the stationary beams is provided with a mechanism for raising and lowering the walking beams in such a way as to minimize the impact of the working beams on the workpieces as they raise the workpieces from the stationary beams. This mechanism includes a number of hydraulic fluid pressure operated cylinders which are connected to the walking beams and operate successively. A number of the cylinders move the walking beams upwards until they come into contact with the workpieces and are then stalled. One or more further cylinders are then brought into operation in sequence until there are sufficient cylinders to increase the force acting on the walking beams until the walking beams are able to lift the workpieces from the stationary beams after which the walking beams are moved longitudinally by a further hydraulic fluid pressure operated cylinder and the beams are then lowered again.

Patent ES-467012-A1 (ES)
Title: Refractory structures for outlet valves for metallurgical vessels
IPC: B22D/
Filed: 1978-02-15
Abstract: In this method, the pressure head (56) of molten metal (2) is measured continuously, via a bottom opening (3) in a tank (1), by weighing. The measured values are used to produce pulses, the frequency of which is proportional to their square root, with the result that the frequency is proportional to the outflow rate. The pulses are counted. When a predetermined count has been reached, the bottom opening (3) is closed by means of a plug (4). The riser level of the filled mould is measured during the pouring of the next mould and, if deviations from a predetermined level are detected, the predetermined count for the filling of the subsequent moulds is corrected. This method allows short cycle times and precise metering of the quantity of metal. It is, in particular, suitable for the filling of casting moulds having a top runner.
