Abstract: The invention concerns a process for purifying naphthalene. The process comprises selective hydrotreatment corresponding to hydrodesulphuration and/or hydrodenitrogenation and/or hydrodehydroxylation and/or hydrogenation of olefins while limiting naphthalene hydrogenation. The catalyst used comprises a matrix, at least one group VIII metal, at least one group VI metal and optionally phosphorous. It has a specific surface area of at most 220 m2/g, a pore volume of 0.35-0.7 ml/g and an average pore diameter of over 10 nm. The process is carried out at 150-325° C. at a pressure of 0.1-0.9 MPa, with an HSV of 0.05-10 h−1, and a H2/naphthalene ratio of 0.1-1.3 mole/mole. The effluent, freed of H2S, NH3 and water, undergoes a naphthalene separation process by distillation or, as is preferable, by crystallisation. Further, recycling the separated tetralin to the hydrotreatment step can substantially increase the naphthalene yield.

Abstract: An apparatus for at least partially forming a brassiere having a pair of male molds provided with substantially conical outer surfaces, which molds are movably supported on a first support device so that the spacing between the molds can be selectively varied. A die assembly is spaced opposite the molds and has a pair of circular openings extending therethrough, which openings are aligned with the molds. Clamping devices are provided for supporting a sheet of flexible material adjacent the die assembly so that the material extends across the openings. A driving device, such as a pressure cylinder, causes relative reciprocating movement between the die assembly and the molds, as by being connected to the molds, so that the molds are linearly advanced toward the die assembly so that the molds project through the openings in the die assembly and deform the material into a pair of cups. Heating means are associated with the apparatus for causing heating of the deformed material.
