A process for the production of a compound of formula (I) which comprises cultivating a microorganism of the genus Streptomyces capable of producing the compound of formula (I) in the presence of one or more fatty acids and/or salts, esters and amides of these acids, whereby the compound of formula (I) is produced, and if desired isolating the said compound. The fatty acid increases the yie...

Recovery of at least one Antibiotic S541 cpd. or chemical deriv. from soln. in an organic solvent comprises contacting the soln. with alumina and adsorbing the cpds., eluting the cpds. and collecting the eluate contg. the cpds.. Pref. the cpds. are of formula (I). (R1 = Me, Et or iPr; OR2 = OH or MeO or a protected OH gp.).

An instrument for measuring the distance between bone parts in a knee joint, particularly the distance between both femoral condyles (A', A'') at the knee end of the femur (A), the instrument including a first element (3, 4, 12) with a first abutment surface (5), which is intended to be brought into engagement against one bone part (A'), and a second element (7, 9), which is displaceably mounted i...

A hearing aid that is compact and efficient and that provides a high degree of control over its frequency response and also over its output level versus input level characteristic. The frequency response control includes an adjustable four pole high pass filter and an adjustable four pole low pass filter, to define the pass band, and an adjustable slope filter, to define the slope within the pass ...

A system for filtering hot flue gas comprises two parallel rows of filter chambers 2, only one of which is shown, connected to common inlet manifold 4 and outlet manifold 16 which extend between the two rows. The filter bags in each chamber in turn are cleaned by reverse flow of filtered gas, which is drawn from manifold 16 through duct 76 to a fan (not shown) and returned through duct 78 to a rev...

An improved welding device with supporting elements for external welding of circular seams in abutting tube sections or curved tube components, a plurality of curved supporting elements forming a complete annular arrangement which is flexibly preloaded and pushes outwards against the inner tube surface in the welding area between tube sections abutting end to end. There is no separate tube-clampin...

A multiprocessor central control unit a switching system with a main memory (CMY) including, aside from a tolerable timing slip, synchronously parallel operated memory block pairs (MB3a/MB3b) during normal operation. The main memory (CMY), together with the central processors (BP, CP . . . IOC . . . ), is connected to a central bus system (B:CMY0/CMY1). The data stored in parallel in the memory bl...
