Title: Process for the production of N,N-diallyldichloroacetamide
IPC: C07C233/13
Filed: 1975-01-28
Abstract: A novel process is described herein for the efficient production of N,N-diallyldichloroacetamide by reaction of diallylamine and dichloroacetyl chloride. The process comprises admixing an excess of diallylamine with sufficient strong aqueous sodium hydroxide such that at all times during the reaction, the pH of the reaction mixture remains above a pH of 10, then slowly adding dichloroacetyl chloride to said mixture under violent agitation, while maintaining the reaction temperature from about -10 to about 100 DEG C to effect production of N,N-diallyldichloroacetamide in yields in excess of 80 percent, while eliminating the production of amine salt by-products.
Patent ES-446037-A1 (ES)
Title: Acoustic emission monitoring system
IPC: G21C17/00
Filed: 1976-03-12
Abstract: Methods and apparatus for identifying the source location of acoustic emissions generated within or on an acoustically conductive medium segregated into a plurality of quadrilateral monitoring zones. A plurality of acoustic receivers are communicably coupled to the surface of the medium respectively at the zone corner locations. Each receiver is responsive to the reception of an acoustic emission to provide a corresponding electrical output. The electrical response of the respective receivers are coupled to corresponding counters in a manner to enable the counters to sequence through their respective counting states. The receiver outputs are monitored to identify the first zone exhibiting an acoustic reception at all four corners. Once such a zone has been identified, all counters are inhibited from sequencing and are locked into the last counting state cycled. Preferably, the counter associated with the last receiver within the identified zone monitoring the acoustic event is locked in the zero counting state as a reference origin for the algebraic operations (more commonly known as triangulation) conventionally used to map the source location of acoustic emissions.

Title: Modular signal-processing system
IPC: G06F15/177
Filed: 1979-02-27
Abstract: A signal-processing system, e.g. for a telephone exchange, comprises n modular processing units each including a pair of identical microprocessors operating in parallel on binary signals arriving over an internal bus, only one microprocessor of each pair being enabled to transmit outgoing messages to that bus while the other operates as a dummy. The two microprocessors are interlinked by a correlating connection enabling verification of their correct operation in response to microinstructions read out from respective microprogram memories thereof under the control of a common clock. A momentary divergence, resulting from a relative lag in the response of one microprocessor to an asynchronously arriving signal bit, results in a delay of the microprogram by one clock cycle to permit resynchronization longer-lasting disparities lead to a deactivation of the microprocessor pair and to the emission of an alarm signal. Processing information individual to the associated peripheral unit is stored in an internal memory connected to the bus general information utilizable by any processing unit is stored in several outside memory banks accessible through external extensions of the internal bus of any such unit. The processing units may be hierarchically organized in several tiers of different ranks.

Title: RF-Input stage
IPC: H04B1/18
Filed: 1981-11-04
Abstract: RF-input stage for TV receivers comprising a field effect transistor in grounded source circuit configuration and a frequency-dependent coupling network arranged between the gate electrode of the field effect transistor and an aerial input for selecting TV signals and transforming the signal impedance. The frequency-dependent coupling network is terminated with a resistor which is arranged between the gate electrode of the field effect transistor and ground and whose value has been chosen so that on the one hand this resistor terminates in conjunction with the input impedance of the field effect transistor the frequency-dependent coupling network with an acceptable reflection factor and on the other hand forms in conjunction with the output impedance of the frequency-dependent coupling network an impedance at which the noise contribution of the field effect transistor is at least substantially at its lowest. This results in a small impedance transformation of the frequency-dependent coupling network and makes it possible to construct this coupling network in a wideband mode.

Patent ES-8305520-A1 (ES)
Title: Smoke detector with a pulse-actuated radiation source.
IPC: G08B17/10
Filed: 1982-06-15
Abstract: A smoke detector contains a pulse-operated radiation source and a radiation receiver arranged externally of the region directly irradiated by the radiation source. The radiation receiver, in the presence of smoke in the radiation region, is impinged by scattered radiation and delivers output pulses. There is provided an evaluation circuit which generates a blocking pulse, and which inputs a resetting signal to a counter device in consequence of the difference of the blocking pulse and output pulse of the radiation receiver. The counter or counting device, in the absence of a resetting signal, is switched further and upon reaching a predetermined counter state triggers an alarm signal. High-frequency electrical disturbances which arise, as long as the radiation source delivers radiation pulses, at most can generate an additional resetting signal for the counter, so that the integrity of the smoke detector against triggering of false alarms is enhanced. If there is connected in parallel to the radiation receiver a NTC-resistor, then there is obtained a smoke detector which responds to a further combustion criterion (temperature).
