Patent GB-2058732-A (GB)
Title: Aqueous suspensions
IPC: C06B47/14
Filed: 1980-08-11
Abstract: Water-soluble crystalline material which has been comminuted in a saturated aqueous solution of the material in the presence of a water- soluble crystal-growth inhibitor having a hydrophobic portion and a hydrophilic portion in its molecular structure is mixed with a deflocculant which inhibits the interaction of the hydrophobic molecular portions whenever the comminuted solid is suspended in water. The viscosity of aqueous suspensions of comminuted solid is thereby stabilised. The invention is especially beneficial in the preparation of aqueous suspensions of finely comminuted ammonium nitrate for use in slurry blasting explosives. With crystal-growth inhibitors such as water-soluble polysaccharide derivatives, long chain aliphatic amines, polyacrylic acids, sulphonated nuclear aromatic compounds, sulphonated dyes or sulphonated polymers the preferred deflocculant, which should be different from the crystal-growth inhibitor, may include water-soluble polysaccharide derivatives, polyacrylic acid, polyvinyl pyrrolidone, sodium lignosulphonate and/or a salt of a condensate of naphthalene sulphonic acid with formaldehyde.

Patent GB-2058854-A (GB)
Title: Apparatus for the manufacture of filling yarn on a shuttleless loom
IPC: D03D47/34
Filed: 1979-12-24
Abstract: The apparatus comprises a feeding roll (9) and a yarn accumulator which deflects the filling yarn creating a loop in its rectilinear path and which is placed between the fabrication nozzle (6) and the feeding roll (9). The filling yarn is deflected from its rectilinear path towards the yarn accumulator by means of two deviation elements (4, 5) for each filling yarn. The first deviation element (4) guides the filling yarn when it deflects it from its rectilinear path by forming a loop; it thus accumulates it. The second element (5) guides the yarn when it emerges from the accumulator, that is when the loop is suppressed in order to confer a rectilinear path. The act of guidance of the yarn when it emerges from the accumulator allows a perfect synchronization of the yarn's end during its insertion in the fluid beam which is displaced along the width of the loom. The deviation element (5) which withdraws the yarn from the accumulator, covers the necessary path during the time needed for the insertion of the woof. This timing is identical for all the filling yarn to be inserted. The deviation element however, which guides the yarn during its accumulation can travel along the path much slower, and the more slowly the more filling yarn there is to be inserted.

Title: Milling thread rolling dies
IPC: B23C5/12
Filed: 1980-11-25
Abstract: A method of milling thread rolling grooves in a thread rolling die of the kind having comparatively wide angle thread forming ribs at the entry end of the dies to carry out the initial thread forming and having steeper angled wide ribs at the exit end of the die to produce a wide-root thread form with steeper flank angles in the resulting workpiece comprises using a milling cutter having a steep angle crest portion conforming to the thread form angle and a wider angle root portion corresponding to the angle of the thread forming ribs. The milling cutter cuts to full depth at the entry end of the dies to produce wide angle crests 41 which form initial wide angled grooves 43 in a workpiece. As milling progresses along the thread rolling die, the cutter operates at a reduced depth to produce grooves by which stage the resulting widened crests 48 in the die have spread the material of the workpiece to produce raised portions 51 and 52 which in the final workpiece become united as a single steep angle thread form. <IMAGE>
