Abstract: 1386346 Reinforced flexible hose PNEUMATIQUES CAOUTCHOUC MANUFACTURE ET PLASTIQUES KLEBERCOLOMBES 28 Feb 1972 [1 March 1971] 9175/72 Heading F2P In a method of making a hollow tubular member, such as flexible hose 1, a sheath receives at least one layer of parallel cables embedded in rubber to form bands 7, 7a which are placed longitudinally on the sheath. The wires are in segments which are mutually parallel within the bands and make an angle with the longitudinal direction of the bands so that the cables extend in a helical fashion on the finished hollow body. As shown, the bands 7, 7a may be laid on the sheath, which is of rubber, in two layers to cover the separations between the bands 7 of the inner layer. The operation is carried out on a mandrel and a further outer sheath is applied to the reinforcement layers, the hose then being vulcanized. The layers of bands may be formed with overlapping edges (Figs. 1b, 1d, not shown). The reinforcement bands are formed from a roll of flat material comprising longitudinal metal or textile wires embedded in rubber (Fig. 2, not shown) by cutting sections transversely from the roll at an angle alpha which is to be the angle between the wires and the axial direction of the hose. The sections are each rotated through 90 degrees and adhered together to form a sheet (4), (Fig. 3, not shown), in which the embedded wires run across the width of the sheet. Longitudinal cuts are made to make narrower bands (5) ready for application on the inner sheath. In the case of a hose having circumferential corrugations (20) (Figs. 6, 6a, not shown) the bands may be overlapped at the edges in the valleys or cylindrical hose portions and leave uncovered areas at the corrugations (20). A further layer of bands may be applied to cover these areas (Figs. 7, 7a, not shown).

Title: Improvements in or relating to addition agents for extreme pressure lubricating compositions
IPC: C10M135/02
Filed: 1944-05-19
Abstract: A monohydric or dihydric alcohol or an alkali metal or alkaline earth metal salt of sulphuric or perchloric acid is added to a sulphurized halogenated hydrocarbon containing water, the addition being sufficient in amount to absorb the water and thereby prevent corrosion of metal containers in which the sulphurized halogenated hydrocarbon is stored.  Suitable alcohols are ethyl, propyl or isopropyl alcohol, ethylene glycol or diethylene glycol while suitable metal salts are sodium sulphate or magnesium or calcium perchlorate.  The sulphurized halogenated hydrocarbon may be prepared by treating a hydrocarbon, such as paraffin wax, kerosene, an aromatic petroleum fraction or a coal tar distillate, with a sulphur halide such as sulphur mono-or di-chloride.  Alternatively the hydrocarbon may be first chlorinated and then treated with an organic or inorganic polysulphide or an isopropyl alcohol solution of aqueous caustic soda and sodium hydrogen sulphide containing free sulphur. Other elements may be introduced into the sulphurized halogenated hydrocarbon such as phosphorus, nitrogen, selenium, and metals, for example lead.  Also, the sulphurized halogenated hydrocarbon may be one intended for adding to mineral lubricating oil in order to produce an extreme pressure lubricant.
