Patent GB-637106-A (GB)
Title: Process and device for the improvement of the dyeing affinity of artificial silk
IPC: D06P5/20
Filed: 1947-03-28
Abstract: <PICT:0637106/IV (a)/1> Artificial silk cakes are subjected, prior to bleaching and drying, to treatment with hot air saturated with water vapour which is forced through the cakes from the inside to the outside of each cake.  The temperature, pressure, rate of flow, and time p  of treatment may be varied according to the thickness and compactness of the cakes and the conditions of subsequent bleaching and drying operations.  The treatment imparts improved and more uniform dyeing affinities to the artificial yarns. Differences between the properties of the yarn taken from the inner layers of the cakes and those of the yarn taken from the outer layers are substantially removed.  The treatment also effects removal of residual carbon disulphide in the case of viscose yarn.  The cakes may be treated in the customary apparatus for passing fluids transversely through yarn cakes.  After they have been treated with the hot moist air they may be subjected to washing to remove acids, and to bleaching and other purifying treatment in the same apparatus. The temperature of the moist air may be 60-90 DEG  C. and the excess pressure may be 30-70 cm. of water.  The moist air may be produced and supplied by apparatus as shown in Fig. 2.  Air is forced by pump 1 through pipe 2 to orifices 10 so that it bubbles through a body of water in tank 9. Steam is introduced through valve 4 and pipe 3 into pipe 2.  The amount of steam admitted is almost sufficient to bring the air to the desired temperature with which it should pass outlet valve 5, the temperature being shown by thermometer 6.  Adjustment of the pressure and rate of supply of the moist air is made by means of orifice-plate 17 which is adjusted in accordance with the reading of manometer 7 and differential manometer 8.  When valve 5 is opened and pressure occurs between this valve and the cake-treating carrier the valve 4 is opened automatically.  Water in tank 9 is maintained at constant level by overflow pipe 11 and the pressure is maintained by the liquid-seal 12.  The water is heated by steam from pipe 13, the quantity admitted being controlled by thermostatic valve 14 connected to thermometer 15 in the tank.  In bubbling through the water, the air is brought to the required temperature and is completely saturated with moisture.  Specifications 319,766, [Class 2 (ii)], 349,681, and 361,733 are referred to.

Abstract: 232,209. Turner Tanning Machinery Co., Ltd., (Assignees of O'Donnell, J. W.). April 10, 1024, [Convention date]. Rotating - tool machines. - A machine for treating sheet materials, and especially hides, skins and leather, of the type in which the work or any part of it can be operated on repeatedly without removal, includes a working- cylinder or cylinders 42, 44, work-supporting and feeding means including a bed roll 20 and a feed roll 28, the former being removable from a workreceiving to a work-clamping position and vice versa, and power means for causing predetermined pressure on the work between the cylinders and bed roll. The feeding-roller, the rear cylinder 42, and the movable front cylinder 44 are each adjustably spring-pressed towards the bed roller. The bed roller and the movable cylinder are moved to the operative position and in the reverse direction to the work-receiving position by the ecentrics 88, 100 mounted on the shaft 86. The rear cylinder is driven in the opposite direction to the front cylinder and thus, whichever way the work is being fed, one of the operating-cylinders which are driven faster than the feeding rollers, will be rotating in the opposite direction to the direction of travel of the work. The necessary halfrotation of the shaft 86 is controlled by the cam block 242 in conjunction with the cam wheel 246, the mechanism being controlled by the treadle 226. The direction of rotation of the feeding- roller is controlled by the lever 300 which moves a double cone operating alternative clutches.

Abstract: 707,302. Change-speed gear. HUPP CORPORATION. April 16, 1951 [April 18, 1950], No. 8848/51. Class 80 (2) Two output selector clutches 28, 31 of a change-speed gear are actuated by striker forks 42, 45 slidable on a common rail 43, and having notches 60, 59, in opposite sides of axially overlapping portions, to be engaged selectively by the spaced arms 54 of a yoke secured to a transverse shaft 55, provided with an operating lever 56. Axial' movement of the shaft 55, possible only in neutral, thus selects either fork 42, 45, whilst its turning movement slides the selected fork in the appropriate direction, these shaft movements being guided by a fixed pin 64 which engages grooves in the shaft 55, one groove 68 being axial and permitting the axial cross-shift movement of the shaft 55 in neutral only, whilst two others 66, 67 are circumferential, and permit the turning movement in the two fork-engaging positions. Spring ball-detents in opposed housings, e.g. 46, 47 on each selector -fork 45, 42 retain the forks in gear and neutral positions by engaging notches in the fixed rail 43. The change-speed gear, which is used as an auxiliary on a tractor, provides direct-drive, one under- and one over-drive by means of the output-mounted selector clutches 28, 31 and a countershaft 35. The gear is mounted in the space between the usual main clutch and existing change-speed gear, its rear casing-wall having a spigot 61 attached by screws to the front wall of the existing change-speed gear, the input wheel of which latter is replaced by a wheel 23 integral with the output shaft 21 of the auxiliary gear, whilst the aligned input shaft 13 of the latter is splined at 14 and piloted at 14a in the usual main clutch.

Title: Improvements in automatic change speed mechanism
IPC: F16H61/02
Filed: 1923-03-29
Abstract: 196,267. Guiraud, J. H. April 13, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Variable-speed epicyclic gearing comprises epicyclic trains in which a varying amount of internal friction is generated by centrifugal masses so as to vary the speed ratio automatically. The driving-shaft a carries a fast pinion a<1> and two loose sleeves c, d. The driven shaft b in a frame a<3> carries two different trains connecting the pinion a<1> to the sleeves c, d respectively so as normally to drive these sleeves together at the same speed as the shaft a. Centrifugal levers d<5>, d<6> carried by the sleeve d have spurs engaging arms c<2> secured to the sleeve c. The effect of rotation is to force a relative displacement of the sleeves c, d, which has the effect of jamming the teeth or the toothed trains together with an increasing amount of friction. Thus at a high speed the gearing turns solid. An overload by reducing the speed, causes slipping, and a reduced velocity ratio.
