Title: Impregnated articles and methods of impregnation
IPC: B01D46/00
Filed: 1977-06-23
Abstract: 1531984 Air filter BONDINA Ltd 23 June 1977 [26 June 1976] 26697/76 Heading BIT [Also in Divisions Dl and D2] An air filter e.g. for use in a coal mine, comprises a non-woven fabric which has areas impregnated with sufficient of a coloured electrically conducting impregnant, e.g. graphite, to render those areas electrically conducting and which also has differently coloured non-electrically conducting areas. The areas may be island areas or stripes. The conductive areas dissipate static charge. The differently coloured non-conducting areas are preferably white or some other pale colour, so that clogging, e.g. with coal dust, can be monitored. The filter is preferably made by applying the impregnant to an absorbent continuous surface, e.g. a felt-covered roller, squeezing the impregnant out of areas of the absorbent surface by pressing a profiled roller against the absorbent surface, and then passing the non-woven fabric to be impregnated between the absorbent surface and a second profiled roller, the profile of the second roller being such that the squeezed areas on the absorbent surface are in register with the recessed areas of the second roller. In the example a 50/50 viscose/polyvinyl chloride fibre blend which had been carded, crosslaid and then lightly needled was impregnated in stripes using the profiled rollers, with an aqueous dispersion of graphite in water. The impregnated fabric was then sprayed with a mixed acrylate/polyvinylidene chloride dispersion as a bonding agent. The resulting air filter material is sewed into a bag which is then stretched over a wire cage.

Patent GB-632447-A (GB)
Title: Improvements in or relating to the production of neutral phthalates
IPC: C07C69/80
Filed: 1947-10-06
Abstract: Neutral phthalates, prepared by the esterification of phthalic acid and or anhydride with an alcohol which is volatile in steam, are isolated by steam-distillation of the crude mixture whilst maintaining the pH at not less than 8 by the addition of sufficient base, e.g. sodium, potassium or ammonium hydroxide or carbonate.  It is preferred to carry out a simple steam-distillation prior to the adjustment of the pH value.  The neutral esters after the distillation are conveniently separated when hot from the aqueous alkaline phase.  The esters are preferably derived from alcohols containing not less than 4 carbon atoms, e.g. octyl and nonyl alcohols; other alcohols specified are methyl to hexyl, benzyl, allyl, phenylethyl and cinnamic alcohols. In the examples: phthalic anhydride is esterified with (1) octanol-2; (2) 2-ethylhexanol-1, and (3) mixed secondary octyl and nonyl alcohols, in the presence of p-toluenesulphonic acid, activated alumina, and sulphuric acid, respectively, as catalysts whilst water is removed azeotropically and the neutral esters are isolated in a pure state by steam-distillation in alkaline solution.

[Also in Group XXX] Articles to be sorted photo-electrically according to their colour are fed to the viewing position by means of a vibrating table along which the articles pass in a single layer so that as each article falls from the end of the table it is deflected or not, according to its colour, by electro-mechanical or electro-pneumatic mechanism. The articles fall from a hopper 18, Fig. 1, on to the table 19 and are kept to a single layer in height by means of a plate 18a. The table and hopper are supported on blade springs 20, one of which forms or is attached to the armature of an A.C. fed electromagnet 21, so that the articles advance steadily along the vibrating table. The surface of the table is provided with grooves 22, Fig. 2, so that the articles reach the end of the table in a number of single rows. Each groove has associated with it a lamp 30 which illuminates each article leaving the end of the table, and a photo-cell which "looks at " the reflected light from each object. According to the photo-cell output means may be operated to deflect articles from tray 34 directly below the edge of the table to tray 34a. The deflecting means may comprise a solenoid-operated plunger carrying a tongue which projects into the path of the falling article or may be an electrically-controlled air blast. Since the recovery time of the solenoid plunger may be large a number of such plungers may be grouped around the path of the article so that as each is operated it switches in the next so that its tongue may start to move forward before the first one is completely withdrawn. The articles may fall from the table on to a belt moving at right angles to the direction of movement of the table so that the articles form a single line when they leave the belt. The first vibrating table may feed a second one vibrating with a different amplitude and having a baffle above it to reduce the layer of articles to a single thickness. U.S.A.
