Title: Improved spindle for textile spinning and twisting frames
IPC: D01H7/06
Filed: 1938-09-16
Abstract: 518,049. Spinning-machines. YORK STREET FLAX SPINNING CO., Ltd., and EMANS, H. G. Sept. 16, 1938, No. 27031. [Class 120 (ii)] A spindle for a spinning machine has two parts, a hollow outer part B to which a flyer A with upwardly extending legs a is fixed, and an inner part B' which projects through the top and bottom of the part B and carries the bobbin or pirn c for winding. A traveller C with an eye c<1> is mounted to slide upon a leg a of the flyer and is moved up and down by the vertically reciprocating traveller plate D to lay the thread on the bobbin. A drag wharve b is secured to the lower end of the spindle part B<1> and has a weighted drag band w which hangs over a notched tension bar E. This bar is adjustable automatically according to the varying diameter of the winding. The bobbin can be doffed without removing the flyer, and the ends of the flyer legs a may be connected by a ring to prevent them from moving outwards under centrifugal force. The bearing F for the outer part B of the spindle fits in the supporting rail G and its lower part extends into a lubricating oil cup h formed with the driving wharve H. Baffles h<2>, h<3> prevent the oil from splashing, and a track h<4> in the outside of the part B assists in the lubrication. Bushes at the ends of the outer part B support the part B<1> and this part is driven mainly by frictional contact with the flyer plate. A few hooks A<5> are provided just below the lower end of the pirn to provide for easy laying on.

Abstract: 384,389. Apparatus for making tyre tubes &c. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, WILLSHAW, H. and YOXON, G. H. B., Fort Dunlop, Birmingham. Oct. 1, 1931, No. 27320. [Class 144 (i).] Apparatus for the manufacture of articles from long lengths of rubber, rubber-treated material, &c. comprises a plurality of operating lines along which the material is submitted to treatment, each line comprising one or more conveyers, and a further common line also comprising one or more conveyers on to which the said lines discharge their products and on which the material is further treated or transported to a place for further treatment. The individual lines may be constructed to produce articles of the same nature but of different sizes while subsequent operations which are irrespective of the size of the article may be performed on the common line. The Figure illustrates the application of the invention to the manufacture of inner tubes. Four operating lines 1 .. 4 are provided delivering by means of intermediate conveyers 6, 7, 8 on to a common line 5. Canted rollers 9 are provided for diverting the material from each conveyer to the succeeding one. In each operating line rubber is fed from mills 20, 21 to a tubing extruder 10. The extruded tube is taken by a driven conveyer 11 to a water tank 12 and thence to an operative conveyer 13 provided with measuring, chalking, and cutting devices 16, 17, 18 and optionally with a device 19 for marking the valve patch position. The conveyer 13 with its accessories may be of the kind described in Specification 381,649, [Group VIIII. Such operations as splicing and vulcanizing may be performed on the common operating line 5. Other articles which may be manufactured according to the invention are tyre treads, flaps, or protector bands for tyres, and in general all articles made from lesser lengths cut from long lengths of rubber or rubber-treated material.

The concentration of dust in a gas e.g. air, is determined by passing the gas through a filter, and measuring the transmissivity or absorption of the dust laden filter to alpha, beta, or gamma rays. The measurement may be made whilst the dust is being deposited on the filter, which may be of paper, felt, or textile material or subsequently. The filter may be fixed, or may be moving continuously or intermittently at variable speeds. Figures for deposits of silica dust using caesium 137 as the particle source are exemplified.
