Abstract: The invention relates to solar collectors comprising a fixed cylindrical reflector and a flattened absorber situated in the central plane of the reflector. A collector according to the invention comprises a cylindrical reflector 1 and a flattened absorber 2 situated in the central plane PP' of the reflector. The transverse cross-section of the reflector comprises a plurality of circular arcs C1, C2 to Cn, C'1, C'2 to C'n which are juxtaposed and are interconnected tangentially. The arcs C1, C2 to Cn and the arcs C'1, C'2 to C'n are symmetrical in twos in relation to the plane PP'. The centre of the arc Cn is in the plane PP'. The centres O1 and O'1 of the arcs C1 and C'1 coincide with the opposite edge of the collector. One application is the production of hot water intended to feed a heating circuit. <IMAGE>

Abstract: The invention relates to a solid flocculating agent comprising at least two components, of which one is aluminium sulphate comprising approximately Al 2 (SO 4 )3. (12-18)H 2 O and the other is an inorganic alkaline compound. The aluminium sulphate and the alkaline compound have such proportions that the ratio between the sum of moles of OH and OH equivalents present in the alkaline compound and the number of moles of aluminium present in the aluminium sulphate is the highest possible but not substan- trally exceeding a value determined bv a specified graph, whereby the flocculating agent when dissolvea in water in a concentration range of 0 02 2 0 moles A 1 gives a clear solution with a high content of multi-nuclei alummwm- hydroxide complexes 
     The invention also relates to a method of producing such an agent, in which an aluminium-sulphate raw material and inorganic alkaline compound(s) are combined in the presence of water in an amount so that a ratio, dust-free composition is provided. The components may be combined in different ways, but it is preferred to mechanically compact an intimate mixture of the components in a finely-divided form and then disintegrate the compacted mass into particulate matter. Another preferred method comtemplates the use of a rotary furnace for producing a granular apent from aluminium sulphate granules and a finely divided alkaline compound in the presence of a minor quantity of water so that the sulphate and the alkali react with each other to form granules.

Abstract: A method of making mixed esters of phthalic acid for use as plasticizers for vinyl plastics. The ester mixture is characterized by having a low volatility while at the same time having excellent solvency characteristics. In its preferred form, the mixed ester is made by first reacting butyl alcohol or a mixture of butyl and octyl alcohols with phthalic anhydride in a mole ratio of about 0.80 to about 1.5 moles of alcohol per mole of phthalic anhydride. Next, an octyl alcohol is added in a stoichiometric amount based on unreacted acid groups along with 20 to 100 percent of the stoichiometric amount of octyl alcohol as excess. An esterification catalyst is added and the reaction mixture heated under vacuum at a temperature less than about 150°C for a time period sufficient to carry the esterification to substantial completion.

Abstract: In order to make a yeast strain capable of expressing a desired polypeptide (e.g. leukocyte interferon D) which it does not normally make or use, it is transformed with an expression vector. This is obtained by producing a transfer vector which has respective origins of replication and phenotypic selection genes derived from both bacteria and yeast, and inserting into it DNA fragments: (i) coding for the desired polypeptide; and (ii) comprising a yeast-derived promoter. The insertion is effected so that 'start' and 'stop' signals are provided, and these and the promoter can control expression of the polypeptide, and so that the replication origins and phenotypic selection genes of the transfer vector are still functional. Thus the expression vector and its precursors can replicate, and their presence can be recognised, both in yeast and bacteria. Bacteria are used for amplification. The yeast-derived phenotypic selection gene may complement a mutation carried by the strain to be transformed.
