Title: Purification of coenzyme a
IPC: C12P19/32
Filed: 1973-08-09
Abstract: 1440369 Polysaccharide; coenzyme A complexes and isolation of coenzyme A affinity substances TANABE SEIYAKU CO Ltd 9 Aug 1973 [10 Aug 1972 (2)] 37899/73 Headings C3H and C3U [Also in Division C2] An immobilized reduced coenzyme A (CoA) in which the amino group of the CoA is bound to a hydroxy group of a water-insoluble polysaccharide through a carbonyl group is obtained by admixing CoA with a cyanogen halide activated polysaccharide at pH 6 to 8. The product (which the invention includes per se) is useful for the separation of the CoA-affinity substance (comprising enzymes or proteins) present in the cell-free extract of a CoA-producing microorganism by contacting the cellfree extract with the immobilized CoA so as to adsorb the CoA-affinity substance on the immobilized CoA, washing the product and then eluting the CoA-affinity substance therefrom. The eluted CoA-affinity substance can then be immobilized by treatment with a cyanogen halide-activated polysaccharide and the resulting immobilized CoA-affinity substance used as an adsorbent in the purification of a crude CoA solution (see Division C2). In an alternative procedure the cell-free extract of a coenzyme A- producing microorganism is admixed with the cyanogen halide-activated water-insoluble polysaccharide at pH 6 to 9 and the resulting immobilized cell-free extract washed and used for the purification of coenzyme A. Examples are given for the preparation of (1) suitable cell-free extracts; (2) a cyanogen bromideactivated agarose; (3) immobilized cell-free extracts from the products of (1) and (2); (4) an immobilized CoA from reduced CoA and the product of (2), and (5) for the use of the immobilized product of (4) for the separation of CoA-affinity substance from a cell-free extract in the manner described above.

Title: Process for the conversion of sewage sludge into a dry material for use as a fertilizer
IPC: C02F11/13
Filed: 1946-12-31
Abstract: A process for converting sewage sludge into a dry fertilizing material comprises partially de-watering the sludge by pressure-applying means and de-watering the resulting solid residue by fermentation.  In a plant for executing the process, sewage sludge is flocculated by means of a precipitant, consisting, for example, of ferric sulphate and ferric chloride, in sedimentation tanks and after decantation is stored in a sludge well.  The sludge is sucked from the well under vacuum to accumulator tanks from which it is forced under pressure to filter presses having frames covered with jute sacking protected by an organic germicide.  The resulting filter cakes are then piled into heaps in the first bay of a fermentation room which is provided with steam pipes on cradles at floor level and as fermentation proceeds the cakes become progressively drier and are transferred periodically to other bays.  After 14 to 18 days fermentation is completed and the cakes are ground in a mill and the ground material passed into a storage silo from which it may be bagged.

Title: Improvements in or relating to machines for casting films or the like
IPC: B29C48/08
Filed: 1930-12-22
Abstract: <PICT:0369608/IV/1> To avoid the entry of bubbles of air into the solution in the casting box of a machine for casting sheets or films of cellulose esters or ethers, the valve controlling the supply of solution from the storage tank is arranged beneath the surface of the liquid in the box so that the presence of air pockets adjacent to the valve is avoided.  Conveniently the solution is supplied through a removable pipe 5 capable of being inserted in the box and provided at its lower end with a chamber 4 closed at its lower end by a sloping wall 4a and provided at the lower part of one side with an opening 6 closed by a slide 7; through this opening the solution flows into the casting box, and the slide 7 is conveniently actuated by a rack-and-pinion mechanism 8, 9.  In working, the pipe is raised from the box, and flushed from air by the passage of a portion of the solution, which portion is rejected, flushing of the pipe being facilitated by giving the latter a substantially streamline form. The casting box may be calibrated so that the end of the pipe can be located at the levels appropriate for casting different thicknesses of film.

Fast on - shaft 2 are gears 17, 18 adapted to be driven in opposite directions from a pinion 6 and from a pinion 8 and idler 55 respectively, when the pinions 6, 8 are alternatively clutched to driving-shaft 1. Thus shaft 2 is driven in one direction or the other as clutch 7 or clutch 9 is operative. A shaft 3, which can transmit at both ends 54, is driven from shaft 2 at four different speeds according to which of the loose gears 19 - - 22 is clutched to shaft 2. 'The mating wheels 49 - - 52 are fast on shaft 3. As valve 27 is moved, oil enters to apply the clutches 23 &c. to the gears 19 &c. Spent oil drops into a tray 71, where larger impurities settle, then into a tray 73 where finer particles settle before passing gauze to the pump (not shown), which is driven from shaft 1, so that the speed clutches can always be operated while the engine is running. A loose clutchable gear 10, Fig. 1, on shaft 1 provides for driving when the hydraulic system fails. A low and constant oil level in the gear sump is provided by a sealed oil reservoir (not shown), filled from a plug 80, Fig. 2, leading to a filter 81. A form is described, adapted for mechanical control, haying claw clutches throughout.
