CF-1 is produced by cultivating a CF-1 producing strain of Streptomyces in an aqueous nutrient medium containing assimiliable sources of carbohydrate, nitrogen and inorganic salts under submerged aerobic conditions until substantial CF-1 activity is imparted to said medium, filtering the fermentation mash at pH 6 to 7 and recovering CF-1 from the aqueous filtrate. It is preferred to use Streptomyces aureofaciens W5 (ATCC 13190), described, but others specified are S. albus, S. rimosus NRRL 2234, S. platensis NRRL 2364, S. hygroscopicus, S. viridifaciens ATCC 11989, S. griseus (streptomycin) and S. albo-niger (puromycin). The broth filtrate is adjusted to pH 8-9, saturated with ammonium sulphate, a carrier particularly a long chain alkyltrimethylammonium chloride added and the mixture is extracted with an alkanol such as butanol. The extract is adjusted to pH 1.5 to 2.0 with hydrochloric acid and back extracted with water.

Abstract: In apparatus for drying a wet web of paper fibres issuing at high speed from a papermaking machine, the web 35 is advanced by a roll 44 into contact with a foraminous surface, e.g. a flexible web 40, passing about a rotatably mounted foraminous shell 38 and advanced beneath a pressure hood 47 from which a heated gasseous fluid under pressure flows through the web into the interior of the shell in which a zone of reduced pressure is maintained as by an exhaust 53 connected to a vacuum source by a duct 54, the pressure drop pressing the web into contact with the foraminous surface. The pressure drop also forces the cellulosic fibres in portions of the web through aperture arranged in a predetermined pattern in the foraminous surface so as to shape the wet web either prior to or during the drying process, or the foraminous surface may have upstanding projections arranged thereon in a predetermined pattern and the fluid pressure is adapted to force the fibres, in portions of the web covering the projections out of the plane of the web and the plane of the foraminous surface. The pressure hood 47 may be subdivided by a partition 62 so that the fluid entering therein from ducts 51, 52 may be at different pressures. In other embodiments, (none shown): i) seal means formed by chambers in which air is maintained at the same pressure as the interior of the shell are positioned at the ends of the shell, Fig. 3. ii) the zone of reduced pressure is created by connection of the interior of the shell with a vacuum source through a hollow journal, Fig. 6, or apertures in one end wall of the shell aligning with a stationary duct. Fig. 7. iii) the flexible web 40 is not utilised, Fig. 8. iv) the rotary shell 38 is replaced by a single endless flexible web passing in a horizontal or inclined path between an upper pressure hood and a lower suction box or boxes, Figs. 9 and 10.

Patent ES-352846-A1 (ES)
Title: Knitting machine with a weft thread laying device
IPC: D04B23/12
Filed: 1968-04-17
Abstract: In a warp knitting machine having a guide 13 for laying in wefts the guide is so mounted that it is raised at the start of each traverse to avoid collision with the inserters 8. The guide lays yarn behind the needles on the sinkers 7, from where it is pushed by inserters 8 across the top of the lowered needle. The guide reverses its traverse before the inserters are withdrawn, and is then raised to clear them. To this end the thread guide rails 11 are mounted between brackets 14 pivotal, in time with the guide movement, about axes 15. The guide, or several guides across the width of the machine are driven by an oscillating cord 12 to which they are attached. The ends of the cord are fixed and the end portions each pass around pairs of pulley blocks (33, 34 Fig. 5 not shown). The inner-. most block of each pair are fixed at opposite ends of a reciprocating rod (35) which thereby oscillates the cord. The guide stroke can be varied by adjusting the rod stroke, the number of pulleys entrained, or both weft insertion may be interrupted while the machine is running and fabric pieces severed and sealed between wefts by heated jaws or a hot air nozzle.
