Abstract: 1484851 Abrading P ERNST 6 Jan 1976 [24 Jan 1975 2 Oct 1975] 00285/76 Heading B3D An abrading machine comprises a workpiece conveying mechanism 3, spaced reels 14, 17 from one of which an abrading belt or web 18 runs alternately to the other and back again, a contact element 10 for pressing the belt or web between the reels against the workpiece 19 when the latter is conveyed by the mechanism 3, the contact element or means 24, 25 associated therewith being driven to move the belt or web at a substantially constant speed between the reels, and respective drive means for each reel operable to rotate the reel receiving belt or web at a speed responsive to the diameter of the web or reel thereon and on the speed of travel of the belt or web and to brake the reel from which the belt or web is being unwound. The conveying mechanism consists of a belt 3 on guide rollers 2 which are mounted on a frame 1 and driven by a chain 6 and motor 5 to carry the workpiece 19 below a roller 9 having a covering 10 which comprises the contact element, the roller being driven by gearing 21 from a motor 22. The roller is supported by bearings 11 in a U-shaped frame 8 which is vertically adjustable by adjusting means 7 to accommodate workpieces of different thickness. The uprights of the frame 8 carry respective winding reels 14, 17 driven by motors 12, 15 and chain drives 13, 16 so that the abrading belt is wound off reel 14 over the roller 9 and on to the reel 17 and vice-versa to abrade the workpiece which is pressed against the conveyer belt 3 by pressure rollers 20. The motors 12, 15 are controlled so that the wind-up speed of the abrading belt is constant. In another embodiment, the contact element is in the form of a beam (26, Fig. 3, not shown) having rollers (24) on each-side. Each motor 12, 15, Fig. 10, has a shaft 65 at one end having a turbo-clutch 63 and toothed wheel 64 for driving its reel, and, at the other end, having a freewheel clutch 66, the outer ring of which is held stationary by a retaining means 67. During winding up, the shaft 65 can turn freely in the clutch 66 and the torque transmitted corresponds to the diameter of the winding and takes place through the turbo-clutch 63. During winding off, the shaft 65 is held and the braking moment is applied by the turbo-clutch. Each reel 14, 17 consists of a tube 54, Fig. 8, having longitudinal slots 62 and housing a rubber hose which is inflatable through a valve 60 to expand the tube to grip the abrading belt.

Title: Process for dyeing cellulosic textile materials with vat dyestuffs
Inventor: SPEKE RICHARD WILLIAM
IPC: D06P1/22
Filed: 1955-01-05
Abstract: In the dyeing of cellulosic textiles with vat dyestuffs by padding the textile with an aqueous dispersion of the oxidized form of the dyestuff, reducing the dyestuff to its leuco form in situ on the textile with an alkaline solution of a reducing agent, e.g. sodium hydrosulphite, and subsequently re-oxidizing the leuco compound, improved results are obtained by effecting the reduction in the presence of anthraquinone-2-sulphonic acid or a salt thereof.  The anthraquinone-2-sulphonic acid may be added to the pigment padding liquor and/or to the reducing liquor or it may be applied to the textile immediately prior to the reduction step. The process is applicable to continuous or discontinuous methods and the molten-metal technique of Specification 620,584 may be employed.  Vat dyestuffs of the anthraquinone and related polynuclear quinones, indigoid and thioindigoid series may be used.  Numerous examples are given.

Filed: 1933-01-11
Abstract: 399,057. Regulating liquid-levels. SULZER FRERES SOC. ANON., Winterthur, Switzerland. Jan. 11, 1933, No. 937. Convention date, Feb. 9, 1932. [Class 123 (i).]' The liquid-level in a container a is regulated by a float d immersed in liquid of a higher specific gravity in a separate float chamber k connected to the container. The chamber k may communicate with the evaporator a of a refrigerator and the lubricant therefrom forms the denser liquid which will not boil when the liquid refrigerant boils. The liquid refrigerant, e.g. ammonia, may be fed directly to a valve r operated by a float d, a wall l preventing the liquid from entering the float chamber. Evaporated ammonia returns by a pipe g and lubricant by a pipe h to the compressor. Alternatively the liquid is supplied through a pipe b to a valve c comprising a plunger m in a chamber o loaded by a spring n and having a bore q with an adjustable throttling device p. When the float rises and closes the valve r, pressure is equalized on both sides of the plunger m which closes the valve c. When the float falls the valve c is opened and refrigerant enters the pipe b. The plunger may be solid and a throttling device p<1> arranged in a pipe q<1> between the condenser wand a pipe s. An auxiliary evaporator v may be provided in the pipe s. A needle valve c adjustable by a stud c<1> in a chamber o carries a plate y connected by flexible liquid-tight diaphragms z<1>, z<2> to the lower wall of the chamber o. The space within the diaphragm z<2> communicates by a pipe b<2> with the liquid space of the condenser wand with the liquid space of the evaporator by a supply pipe b<3> which also communicates with the space between the diaphragms. When the valve r is closed, valve c closes, and when the valve r opens, pressure between the diaphragms exceeds the pressure in the chamber o and valve c opens. By opening valves s<3> or s<7>, the throttling device p<1> is connected to the vapour space of the condenser w or to the liquid space of an oil separator w<2> on the condenser.
