IPC: A63C5/14
Filed: 1985-02-07
Abstract: A ski core (1, 18) made of plastic material comprises cavities (4) which enable to reduce its weight and solid areas (23) distributed throughout the volume of the ski core, throughout the ski thickness. The core is flow formed from a stratified or laminated base product comprised of duromer or thermoplastic synthetic material reinforced by a fibre mat. The ski core (1, 18) of which the side pieces (17, 24) may be integrally formed by extrusion with the core, preferably presents a stratified area (3, 22) extending on at least almost all the base surface of the ski core of which the course corresponds to the junction between the extrusion half-moulds (7, 8). This stratified area (3, 22) may advantageously be adjacent to the upper side or the lower side (5, 2) of the ski core or may also follow an undulating course between the upper side and the lower side (20, 21) of the ski core (18). In a preferred embodiment, the cavities (4) may have a cylindrical shape, the solid areas (23) being respectively configured as ribs extending throughout the thickness of the ski core. The invention also relates to a ski comprising said ski core.

Title: Improvements in the manufacture of picric acid
IPC: C06B21/00
Filed: 1931-01-06
Abstract: Picric acid which is contaminated with incompletely nitrated material is purified by suspending it in an acid mixture capable of completing the nitration of the impurities, which are liberated by stirring and heating the suspension to a temperature such that the picric acid is melted.  Thus phenol or a phenolsulphonic acid may be treated with sulphuric acid and nitric acid according to the strong acid methods and at the completion of the reaction the temperature is raised until the picric acid crystals melt.  On cooling the purified picric acid separates out.  In examples: (1) phenol is sulphonated and then nitrated and after the picric acid crystals have separated out, the temperature is raised to melt the crystals the whole being agitated, and finally the mixture is cooled allowing the picric acid to separate out; (2) picric acid crystals contaminated with dinitrophenolsulphonic acid are added to a mixture comprising nitric acid, sulphuric acid and water in a cast iron vessel and the mixture is heated to melt the picric acid crystals, the mixture then being cooled.  Specification 126,368, [Class 2 (iii), Dyes &c.], is referred to.

Class 89 (i) Relates to locknuts of the type in which a coned inner threaded member is contracted on to the bolt member by an unthreaded outer bearing member and consists in a detailed construction whereby overtightening of the nut is prevented, the end of the inner member is prevented from touching the bearing surface, and repeated use is possible. The inner member has a polygonal head portion 14, Fig. 2 and a conical part axially slotted at 18. One of the slots may extend across the head portion also. The outer member has an internally coned bearing part 32 with an extension 42 shaped to fit the polygonal part of the inner member and flanged in at 50 to prevent separation of the parts. Shoulders are formed on the two parts at 28 and 46 and these shoulders engage in the locked position of the parts to prevent overtightening of the nut and contact of the inner member with the bearing surface. The angle of the cone is preferably between five and ten degrees and that of the outer member exceeds that of the inner by two degrees. In a modification, particularly for deep nuts, the head and conical skirt of the inner member are separated by a cylindrical portion, a corresponding portion, having slight clearance, being formed in the outer member.
