Patent ES-479520-A1 (ES)
Title: Purification of Olefins
IPC: C07C7/148
Filed: 1979-04-11
Abstract: A process for the purification of olefins having from 2 to 5 carbon atoms, in which the olefin is contacted with at least one phosphorous complex having the formula: M[P(OR)3]n in which M represents Ni, Co or Fe, n is an integer from 2 to 4 and R represents a hydrocarbyl group having up to 18 carbon atoms which may be substituted. The purification method frees the olefins, e.g. ethylene propylene, butene-1 and butene-2, from impurities mainly consisting of CO, COS, O2, allenes, acetylenes and butadienes, reducing their content to acceptable values for polymerisation of the olefins in low pressure processes with the use of high-yield catalysts.

Title: Improvements in and relating to channel-shaped sealing strips
IPC: B60J10/00
Filed: 1979-06-18
Abstract: The strip disclosed has a channel-shaped metal carrier (5) which is embedded in synthetic plastics or rubber material (6) which defines inwardly directed gripping ribs (10, 12).

Title: Aqueous bleach compositions
IPC: C11D7/54
Filed: 1981-03-31
Abstract: The present invention relates to aqueous alkaline bleach compositions containing hydrogen peroxide.

Patent ES-8308123-A1 (ES)
Title: An apparatus and a method for processing an analog signal, together with a corresponding auditory prosthesis circuit
IPC: H04R25/00
Filed: 1982-05-14
Abstract: An apparatus and method are disclosed for encoding only the maximum and minimum values of an analog signal in the presence of broadband noise so that the original analog signal may be subjectively reproduced for the human sensory system. The basic apparatus includes a differentiator for detecting the times of occurrence of minimum and maximum values of the analog waveform including the minimum and maximum values of the noise superimposed thereon and for converting the times of occurrence of minimum and maximum values into time-axis zero crossings, and a clipping circuit having a bandwidth substantially greater than the bandwidth of the analog signal for encoding the time-axis zero crossings into transitions of a binary signal. The binary signal contains information solely concerning the times of occurrence of the minimum and maximum values of the original analog signal and may be presented directly to the human sensory system or after further signal processing. Because the human sensory system is more receptive to the occurrence of minimum and maximum values of a waveform, the sensory system will substantially reproduce the original analog signal from the encoded waveform.

Patent ES-8406948-A1 (ES)
Title: Method of fabricating carbon composites.
IPC: C04B35/83
Filed: 1982-08-10
Abstract: An improved method of making a carbon composite product wherein a fabric comprised of oxidized or otherwise stabilized polyacrylonitrile fibers is heat treated and then coated with a closely controlled amount of a carbonaceous binder such as a polyimide resin. The fabric is then further heat treated to thermally fuse the resin to the fabric to form a rigid, easily handleable material. The carbonaceous binder is applied to the fabric in a manner whereby substantial encapsulation of the individual fibers is avoided. Next the material is cut into swatches of a predetermined size and shape and the segments are arranged into a basic or starting substrate having a volume greater than the desired volume of the end product. The basic substrate thus formed is then subjected to controlled temperatures and pressures to form a shaped substrate having a known fiber volume, a high degree of open porosity and a shape substantially corresponding to the shape desired of the end product. During this step, the fiber volume of the substrate is adjusted and the segments are fused together to temporarily hold them in position within the substrate. The shaped substrate thus formed is then pyrolyzed to form a carbon fibrous substrate which is densified in a freestanding configuration by the deposition of pyrolytic carbon interstitially thereof to form the desired end product. Because the portions of the fibers which are not encapsulated with binder are free to move, stresses generated in the substrate during pyrolyzation due to material shrinkage and the like are effectively distributed.

Title: Smoke detector.
IPC: G08B29/00
Filed: 1982-11-09
Abstract: A smoke detector is disclosed having a radiation source operated in a pulsed mode. Externally of a direct radiation region of the radiation source there is arranged a radiation receiver which, in the presence of smoke or other particles emanating from a combustion process and located in the radiation region, is impinged by scattered radiation and delivers an output signal to an evaluation circuit. The evaluation circuit contains switching elements which, when the number of source output signals or pulses exceeds a predetermined threshold value for the number of source output pulses, delivers an alarm signal. Near to the radiation receiver there is arranged a reference cell in the direct radiation beam of the radiation source, this reference cell controlling the emission of radiation by the radiation source. Further, there is provided circuitry which, in the presence of a slow change in the amplitude of the receiver output pulse, adjusts an amplitude threshold value set for the amplitude of the receiver output pulse at a rate corresponding to a time-constant of more than one minute. Consequently, there is obtained an output signal of the radiation receiver which is dependent upon the smoke density and which is independent of the contamination or soiling of the smoke detector.
