Abstract: Anaerobic adhesive compositions comprise at least 20% by weight of one or more monacrylate or monomethacrylate esters of polyhydric alcohols, said polyhydric alcohols containing a chain of from 2 to 16 carbon atoms which may if desired be interrupted by one or more ether oxygen atoms, and from 0.1 to 10% by weight of an organic hydroperoxide.  The mono-esters are suitably those of mono-, di-, tri- or tetraethylene, propylene and butylene glycols and of glycerol and erythritol.  Hydroperoxides specified are cumene hydroperoxide, tertiary butyl hydroperoxide and methyl ethyl ketone hydroperoxide. A copolymerizable monoethylenically unsaturated compound may also be present, e.g. acrylic or methacrylic acid or an, ester, amide or nitrile thereof, or a vinyl compound such as styrene and, also, a cross-linking monomer, e.g. divinyl benzene, a dimethacrylate ester or allyl methacrylate.

Title: Separation of particles by size
Inventor: SMALL HAMISH

Filed: 1970-09-18
Abstract: 1,273,865. Wet separation of solids. DOW CHEMICAL CO. 18 Sept., 1970 [19 Sept., 1969], No. 44625/70. Heading B2H. Solid particles dispersed in a fluid are separated according to size by passing the dispersion through a porous bed of solid particles of larger size than the particles to be separated, eluting the bed with further dispersing fluid to cause the particles to pass right through the bed and collecting the effluent from the bed wherein larger particles are first removed from the bed and successively smaller particles are subsequently removed therefrom. It is believed that the larger particles leave the porous bed first because they are not delayed in the smaller portions of the fluid passageways where the effluent flow is slower. The bed may be constituted by glass, plastics or metal particles, examples of which are given. In a particular example particles of a synthetic, e.g. polystyrene, latex is dispersed in deionized water and the dispersion stabilized by the addition of sodium lauryl sulphate. A column is packed with sulphonated, crosslinked polystyrene beads and deionized water from a reservoir is passed through the column by means of a syringe pump via a sample injection chamber. A sample of the dispersion is then introduced through the sample injection chamber. The discharge from the column is connected to a solids detector in the form of a light scattering apparatus which detects turbidity in the effluent from the column and records it on a strip chart. The plot on the chart indicates sharp separation between large and small particles.

Title: A process for the production of 5-nucleotides
IPC: C12P19/30
Filed: 1961-12-19
Abstract: 51-Nucleotides are produced by suspending microorganisms in an aqueous solution of pH 7,5 to 11, at 25-45 DEG C. for such time for the ribonucleic acid of the organism to be degraded into 5 nucleotides which migrate from the cells into the alkaline medium, and separating the liquid from the solid.  Sufficiently grown microorganisms separated from their culture medium may be suspended in a buffer at 7,5 to 11 or a microorganism may be grown in a nutrient broth, the pH of which is adjusted to 7,5 to 11 at a suitable stage and the suspension is maintained at 25 to 45 DEG C. The preferred pH range is 8,0 to 11,0.  The organism may be treated with phenol cresol or an alkali metal deoxycholate to damage the cell wall to accelerate the process.  The suspending medium may contain as anions phosphate, pyrophosphate, polyphosphate, arsenic or citrate. A separated organism may be pretreated by freezing and subsequent thawing prior to autolysis. Suitable organisms comprise bacteria, yeasts, fungi imperfecti, moulds, actinomycetes, of which numerous examples are given. Buffer components specified include glycine, trisaminomethane, sodium chloride, ammonium chloride, potassium chloride, borax, p  sodium and potassium phosphates, ammonium sulphate, sodium acetate and citrate.  The cell suspension may be allowed to stand or may be shaken, for 1 to 10 hours.  The excessive activity of nucleotidases may be inhibited, e.g. by adding alkali metal arsenate to the suspension.  In the examples after the autolysis is completed, the 51-nucleotides accumulated in the aqueous solution are recovered and purified by filtering the cells and solids off, passing the acidified filtrate through active carbon in a column, eluting the adsorbed nucleotides with ammoniacal ethanol and finally purifying with anion exchange resins.
