Title: Improvements in or relating to flexible tubes
IPC: H01H3/22
Filed: 1935-10-10
Abstract: 460,606. Flexible tubes. FREUDENBERG GES., C. Oct. 10, 1935, No. 28010. Convention date, July 15. [Class 99 (ii)] [Also in Group VIII] Flexible tubes impervious to organic solvents, e.g. motor fuels, are prepared by swelling and shredding collagenous material so that the individual fibres are retained, forming the material into tubes, sizing the tubes with gelatine and incorporating in them water insoluble softeners. The disintegrated collagenous material may be formed into threads or bands by extrusion, these being braided or wound on a mandrel, the tube so formed being then coated, e.g. by spraying, with the collagenous material; or tubes so formed may be combined concentrically with tubes made as such by extrusion through an annular die. The tubes are then sized with gelatine solutions by pumping the solution through the tubes in the case of braided tubes or by sizing during winding when thin strips are wound on a mandrel. The tubes are then converted into elastic and water-resistant condition by treatment with softeners such as train oils, castor oil, or paraffin oil. Swelling agents are applied to the tubes before treatment with the softening agents so that they may take up the latter ; suitable agents are glycol, glycerine or mixtures of such with ethyl and methyl alcohol, and the swelling agents are preferably removed before application of the softeners by treatment with organic solvents. After application of the softening agents the tubes are dried in air which results in oxidation of oils such as train oil and castor oil. They are then dried or steamed, washed with organic solvents such as trichlorethylene and again dried. They may be hardened with formaldehyde &c. at the end of the treatments. Specification 313,747, [Class 28 (ii)], is referred to.

The ring gear 26a is stationable by a brake B 1  and clutchable to the input shaft by a clutch K 1 , and the planet carrier 26d of the planets 26c is fast with the ring gear 27a which is stationable by a brake B 2 . The planets 27c are fast with planets 28b which mesh a ring gear 28a stationable by a brake B 3 , and the planet carrier for these planets is fast with a ring gear 29a of a two-ratio train having planets mounted on a carrier fast with an output shaft 24, and a sun gear 29b stationable by a brake B 4  and clutchable by a clutch K 2  to the output shaft 24. Fig. 4 shows which clutches and brakes are engaged to obtain each ratio, an X indicating that that clutch or brake is engaged. It will be noted that in certain shifts, namely second to third, fourth to fifth, and sixth to seventh, four clutches and brakes are involved, and, for example, in shifting from fourth to fifth initially brake B 2  and clutch K 2  are engaged, and in the shift brake B 2  is disengaged and brake B 1  applied, so that momentarily the sixth ratio is obtained, and then the clutch K 2  is disengaged and the brake B 4  applied to give the fifth ratio. In order to avoid the undesired momentary increase in output speed which the momentary engagement of the sixth ratio would entail, the driving motor, which is a variable-speed electric motor has its speed temporarily reduced to avoid such an undesired increase in output speed.
