Patent ES-472902-A1 (ES)
Title: Aqueous solution of monovalent gold and ammonium sulfite complex, process for the preparation thereof and electrolytic bath obtained therefrom for the plating of gold or gold alloys
IPC: C25D3/48
Filed: 1978-08-29
Abstract: Aqueous solution of monovalent gold and ammonium sulfite complex. As opposed to the corresponding alkali-gold sulfite solution, this solution is stable under slightly acidic pH conditions and can be used advantageously for preparing electrolytic baths for the plating of gold and gold alloys having a great flexibility of use and a particularly long working life. This solution is prepared, in a very economical manner, by adding ammonia to an HAuCl4 solution which results in the formation of a precipitate, then by dissolving this precipitate in an aqueous ammonium sulfite solution.
Patent ES-476721-A1 (ES)
Title: Concerning a cyclically operating container forming machine
IPC: G05B19/042
Filed: 1979-01-10
Abstract: The control device serves to increase the efficiency of a machine, which is subdivided into individual sections, for producing objects from glass. Each section has a shaping device (14). Each shaping device is assigned a section computer (13) which produces control signals for the shaping device (14) every working cycle of the machine as a function of a control program stored in a storage device (16) and of time switching values. The relative position of each working step within the working cycle is defined by a switch-on time and a switch-off time. These switching time values are stored in the section computer (13). The difference between the switch-on time value and switch-off time value is the dwell time available for carrying out the respective work step. This dwell time can be changed with the aid of a control console (21) by manual displacement of one or of both switching time values. The section computer (13) is programmed in such a way that it automatically prevents a change in the dwell time if a negative dwell time which is in practice not possible were to be produced by this change.

In the same dosage they also effect inhibition of monoamino-oxidase in the brain of rats and in the liver of rats. Furthermore, they intensify the "head twitch" induced by 5-hydroxy-tryptophan, and are distinguished by good tolerance. The compounds of the general formula I and their pharmaceutically acceptable acid addition salts can therefore be used as psychopharmaceuticals and in particular as antidepressants.
