Abstract: The invention concerns an arrangement for collecting solar energy, comprising a number of parallel, elongate reflection elements 1, concave towards the radiation incidence direction. Each element has a collection element 2 lying in the element's 1 longitudinal direction for collecting radiation energy, comprising tubes 3 which carry a heat-exchange medium and which are connected to a circulation system for the heat-exchange medium. The essential point of the invention is that each of the parallel reflection elements 1 has been designed to rotate around its longitudinal axis 4, and that the reflection element is connected to a common mechanism which serves to control the element's positioning. The said mechanism can comprise a strip 11, lying under the reflection element 1 and moving in the element's tranverse direction, and pull-wires 12a-12e, 13 which connect the elements with each other and with the strip 11. By controlling the reflection elements' 1 positioning, they can in each individual case be directed in accordance with the radiation incidence angle, alternatively they can serve to control the heating of the heat-exchange medium and also prevent its over- heating. <IMAGE>

Date Mar. 3, 1994The present invention relates to an environmental-friendly process for reducing the content of chloride in a liquor inventory of a chemical pulp mill. According to the invention, in a recovery system for pulping chemicals containing sulphur and an alkali metal, precipitator dust formed in a recovery boiler is collected and withdrawn, dissolved in water and electrolyzed for production of chlorine or hydrochloric acid in the anolyte. Since the dust normally contains a large amount of sodium sulphate, sulphuric acid and sodium hydroxide can also be produced in the electrolysis. To reduce the content of impurities, before the electrolysis, the pH of the aqueous solution is adjusted to above about 10 to precipitate inorganic substances which are separated-off together with flocculated or undissolved substances.

Abstract: A system for overlaying digital character signals on an analog video source signal including a predetermined color subcarrier includes a subcarrier phase lock loop (14), a digital character generating device (28), a digital video encoder (18), and a switching device (24). The subcarrier phase lock loop separately generates a color subcarrier and a system clock signal which are locked to the color subcarrier of the analog video source signal. The digital character generating device detects horizontal and vertical timing of pixel information in the analog video source signal, and generates digital character signals that are to be overlaid in predetermined pixels of the analog video source signal. The digital video encoder is responsive to the color subcarrier and system clock signals for generating a separate color subcarrier which is locked to the color subcarrier of the analog video source signal. The digital video encoder also converts the digital character signals from the digital character generating means into an analog video output signal that includes the color subcarrier generated in the digital video encoder. The switching means directs the analog video output signal from the digital video encoder or the analog video source signal to an output of the system during pixels times when a digital character is to be overlaid or not overlaid, respectively, on the analog video source signal. <MATH>

Abstract: Esters of a cyano acid are prepared by treating an ester of an acid having the formula CH3.C(O).(CRR)n.COOH, where R is H or alkyl and n is 0 to 4, with HCN, acylating the product obtained to produce an acoxy derivative, and then deacylating (removing a molecule of acid), the acoxy derivative to produce an unsaturated cyano acid ester.  The acid may be acetoacetic, or alkyl derivatives thereof, pyruvic, levulinic, g -acetylbutyric, a - or b -methyl or ethyl levulinic, o -acetyl valeric, a -or b -methyl-g -acetyl butyric, or a a - or a b - or b b -dimethyl levulinic acid.  The products copolymerise with various monomers to give rubber-like materials.  The esters may be hydrolysed to the acid amide and thence to the acid.  Examples give the preparation of methyl b -acetoxy-b -cyanobutyrate, methyl b -cyano-2-butenoate, methyl b -cyanocrotonate, ethyl b -acetoxy-b -cyanobutyrate, ethyl b -cyano-2-butenoate, and ethyl b -cyanocrotonate.  The propyl, butyl, benzyl, furfuryl, tetrahydrofurfuryl, cyclohexyl, methylcyclohexyl esters and their chlorine substitution derivatives may also be prepared.  The methyl and ethyl esters when copolymerised with butadiene give rubber-like products.  They may also be copolymerised with acrylonitrile, a -chloroacrylonitriles, a -alkyl acrylonitriles, acrylates, a -chloroacrylates, methacrylates, ethacrylates, styrenes, vinyl chloride, vinylidene chloride, isoprene and dimethyl butadiene.

Initially the circuit is not self-oscillating but on the bridge being temporarily unbalanced, as by varying in one sense the value of capacitor 3 or 4, oscillations commence and are rectified by a detector 22 whose output is applied to the variable junction capacitance for back-biased semi-conductor diode 26 shunting one arm of the bridge so that the oscillations are sustained and rapidly increase in amplitude, and the detected output operates a relay 21. Potential dividing 24, 25 determine the initial bias of the semi-conductor diode 26 and backlash of the system, a different degree of variation of capacitor 3 or 4 stopping the oscillations and de-energizing the relay.
