Title: Improvements in and relating to textile spinning frames
IPC: D01H1/36
Filed: 1965-06-03
Abstract: 1,116,564. Builder motion for ring-frames. DENCO A.G. 3 June, 1965 [5 June, 1964], No. 237l3/65. Heading D1D. In a ring-frame with the rotation of the drum from which the chain is released to provide the gain, a spring is wound which is released at the end of a set to aback-rotate the drum to starting-point. The apparatus may be combined with apparatus for raising the rail to wind a tip-bunch and for lowering and locking the ring-rail in doffing position. In Fig. 3, during a wind the chain 23 is intermittently let off a drum 26 to allow the ring-rail to be raised by a counterweight, as a gear 33 forwardly indexes a gear 46 at each traverse. Gear 46 is fixed to a sleeve 43 which drives the chain-drum 26 through a oneway clutch 49, thereby winding-up a spring 62 which has one end anchored to the sleeve and the other to a plate 50 splined to a shaft 39. To prevent premature unwinding of the spring, a roller cage 65 has openings for rollers 67, Fig. 6, which engage flats 68 on the plate 50. A compression spring 70 between a flange on the cage and an edge of one of the flats causes the rollers to be jammed against an inner surface 69 of the drum to prevent it rotating in the reverse direction. The lock thus established is released when a lever 81 is rocked by a link 79 when a solenoid is energized. Rewinding continues until a lug 61 engages an. adjustable stop 58. A hand-lever is provided for releasing the lever 81 when it is desired to adjust the relative position of members 61, 58.

Patent GB-738009-A (GB)
Title: Improvements relating to wax compositions
Inventor: JR WILLIAM TYNDALL KNOX
IPC: C08L91/06
Filed: 1952-09-23
Abstract: A wax composition, particularly suitable for coating or impregnating fibrous materials, comprises a mixture of scale wax and 1-20 per cent of a microcrystalline wax, the latter wax being derived from residual oil, having a melting point above 145 DEG  F. and having an oil content in the range of about 1-10 per cent. The composition may be used for coating paperboard to render it liquid-proof and thus suitable for preparing milk cartons or frosted food containers.  For comparison purposes, compositions consisting of refined paraffin wax and microcrystalline wax, with or without oil, are described.  A process is described for preparing the scale wax-microcrystalline wax blend from a waxy crude petroleum oil by fractionally distilling the oil to yield, together with other fractions, a waxy distillate fraction and a residual oil and isolating waxes from these latter two fractions. The waxy distillate fraction is dissolved in a mixture of methyl ethyl ketone and toluene and the solution cooled in stages, and the wax which separates filtered off.  This slack wax is washed, freed of solvent and then de-oiled by sweating or solvent treatment to yield the scale wax.  This may be further refined by treatment with sulphuric acid or fuller's earth, bauxite or other absorbent materials, or by hydrogenation under mild treating conditions.  The residual oil is deasphalted, preferably with liquid propane, and then cooled, if desired in stages in the presence of additional propane, and the precipitated wax is separated.  This microcrystalline wax may be used as such after removal of solvent, or may first be de-oiled by adding further propane and re-chilling.  The scale wax and the microcrystalline wax are then blended.

Abstract: 444,543. Centrifugal machines. AOUST, L., 10, Rue Duchene, Firminy, Loire, France. Aug. 27, 1935, No. 24007. Convention date, Aug. 27, 1934. [Class 23] In a centrifuge for the treatment of paper pulp and like material, the pulp is fed into the bowl through an annular conical feeder coaxial with the bowl and extending downwards nearly to the bottom of the bowl. The fixed spindle 2 is supported in elastic rings 27, 28 in the frame 25 and the swan neck 29 respectively, and the bowl 1 is rotated round the spindle on bearings 3, 4 by a belt drive from the motor 30. Two conical tubes 22, 23 surround the central part 6 of the bowl ; the space between them forms the feed channel and is in communication with the feed trough 21 which has a narrow cross plate 33. The bowl contains a circular grid 7 formed of bars 8 which do not reach the bowl wall, a grid 10 formed of concentric rings 11, and an adjustable grid formed of two washers 13, 14 with radial slits 15 in each, the overlap of the slits being varied by the rotation of the washer 14. A wash pipe 31 is arranged at the side of the bowl. The material supplied to the feed trough rises to the height of the rim 24 and flows over it to the space between the tubes 22, 23. The material then drops on the deflecting plate 5 rotating with the bowl and is thrown to the wall. As it passes upwards a cushion of pulp is formed on the wall and long threads are held back by the grids 7, 10. The top plate 18 of the bowl controls the thickness of the cushion of pulp on the bowl wall and the light impurities are retained by the washer 13. The purified pulp passes through the slots 15 and over the plate 18 to the trough 26. Just before the machine stops, washing water is supplied to the tube 31 ; jets from the nozzles 32 clean the bowl and the grids, the material leaving by the outlets 19. The nozzles may be placed so that the water jets keep the bowl rotating. In a modification, the washers 13, 14, which control the outlet of the pulp, are replaced by rims 36, 38, Fig. 7, with slots 37 in each for the inward passage of pulp for discharge over the plate 35. Radial wings 40, which may or may not extend to the bottom of the bowl, are arranged to assist in the rotation of the pulp.
