Title: Surface-structured bristles, process for producing the bristles and a brush or interdental cleaning device made from the bristles.
Inventor: WEIHRAUCH GEORG
IPC: B29C48/16
Filed: 1998-03-13
Abstract: The invention pertains to a process for producing surface-structured synthetic bristle material by extrusion of a monofilament. Before or during extrusion, granules are added to a first thermally melted synthetic material which constitutes the principal component of the monofilament. The granules consist of a second synthetic material with a higher thermal stability than the first. The grain size of the granules is such that the monofilament when subsequently stretched undergoes a more marked transverse contraction in cross-sections with few or no granules than in cross-sections which have granules. The invention also pertains to a surface-structured bristle made from the principal component first synthetic material in which granules of the second synthetic material are embedded so as to be more or less completely covered and form a structure at the bristle surface. The invention futher pertains to a brush, in particular a toothbrush or interdental cleaning device, with a plurality of bristles gathered as required into bundles, at least some of the bristles having the structure indicated above.

Title: Prodn of iron with low sulphur content
IPC: C21C1/02
Filed: 1969-11-04
Abstract: Iron melts with a low sulphur content are produced by the addition of CaO, and optionally CaC2 to the melt, together with practically equal amounts of Na2CO3 and NaCl, the combined amount of the latter two components representing not more than one-fourth of the total mixture. The combination of CaO, Na2CO3 and NaCl, optionally together with CaC2, enables the iron melt to be more rapidly desulphurised than by use of the compounds individually, or in pairs of compounds. In addition, less gas development occurs, and the coating of the pair is not attacked.

Title: Separating lactams from sulphuric acid solutions - - using mother liquor to produce dihydrogen phosphates
IPC: C07D201/16
Filed: 1971-05-07
Abstract: In a continuous process for sepng. lactams from reaction mixts. contg. conc. H2SO4 and possibly free SO3 by means of a water-immiscible or poorly miscible organic solvent, the bond between lactam and H2SO4 is weakened, before the extn., by addn. of a soln. contg. ammonium or alkali hydroxide or carbonate, in amt. such that the molar ratio of sulphate formed: sulphate + free H2SO4 is is not 1/8:1. The aq. soln. contg. H2SO4 and ammonium or alkali sulphate remaining after extn. of lactam is used for the decompsn. of crude phosphate, to form calcium sulphate and a soln. contg. free H3PO4; after removal of CaSO4 and neutralising with ammonia or caustic alkali, this soln. is withdrawn as a dihydrogen phosphate soln. from which solid ammonium or alkali dihydrogen phosphate is recovered by evapn. The aq. soln. reamining after the lactam extn. is fairly conc. but has a low crystallisation point; it can therefore be easily transported, and lactam prodn. and phosphate decompsn. do not need to be carried out in one locality.

Abstract: 1431605 Delivering sheets XEROX CORP 19 Dec 1973 [29 Dec 1972] 58829/73 Heading B8R A sheet-stacking receptacle comprises an inclined base 205, Figs. 3, 4 and 9b, for supporting the face of the stack, a front wall 207 against which the leading edges of the sheets abut, the wall 207 being narrower than the body of the base, Fig. 4, and at each side of the wall a pivoted hexagonal plate member 262. Each sheet strikes the members 262 and causes them to swing forwardly, and as they return into contact with the top sheet the sheets are urged downwards thereby to avoid the sheets riding up the wall 207. A plurality of receptacles form an assembly supported by three cam followers 211, 211, 213 in helical cam grooves 221, 227 in cam members 223, 224, 225, whereby, as the cam members are intermittently rotated in response to the direction of sheets approaching the assembly, all the receptacles are moved upwards. The grooves are so constructed that at any given time the receptacles are arranged in groups of five separated by a gap larger than that between receptacles in a group, while at the zone where sheets enter the receptacles, a larger gap is formed. Each receptacle carries a pivoted arm supporting a roller which rests on the stack in the receptacle below. By delivering one sheet formed from each original in a xerographic copying-machine into each receptacle, returning the receptacles to their lowest position, and repeating the process for each original, collated sets are obtained.
