Title: Rolling mill structure
Inventor: KALBERKAMP HERMAN J
IPC: B21B13/00
Filed: 1964-04-28
Abstract: 1,012,609. Rolling. MESTA MACHINE CO. April 28, 1964, No. 17636/64. Heading B3M. A rolling mill stand is adapted to interchangeably receive two-high and four-high sets of rolls, the sets of rolls being shifted on a sled transversely to and from a window of the mill housing. In a four-high arrangement, Fig. 4, the upper and lower working roll chocks 38 and 36 are located in recesses 37a and 30a of the upper and lower backing roll chocks 32a and 29a. The chocks 32a engage in inwardly facing recesses in transverse beams 25 which are urged upwardly by an hydraulic balancing piston 17, thus urging the chocks against screwdowns 39. Pneumatic cylinders 66 acting through links 67 and locking lugs 69 clamp the chocks in the housing windows. For removing the rolls, the upper two rolls are lifted by the piston 17, for positioning spacers between the working roll chocks, so that all four rolls are supported on a sled 27. A rack 55, in plan in Fig. 1, is then attached at 58 to the sled and drawn by a piston to the left. The roll assembly is moved by pistons 51 and 52 sideways on tracks 50 until a two-high set of rolls is aligned with the housing window. This set is then positioned in the housing, Fig. 9. The upper roll chocks are again supported by the beams 25, although the rolls are of shorter length. The plan view of the stand in Fig. 7 shows alternative drive systems for the rolls. The four-high set is driven by a motor 43 through gear-boxes 44 and clutches 45 and by way of the shafts of motors 40 to actuate the screwdowns 39. For a higher speed screwdown when two rolls are used, the clutches are disengaged and the two motors 40 drive the screwdowns.

Title: Production of articles of cellulose triesters by wet spinning
IPC: D01F2/28
Filed: 1956-06-08
Abstract: Shaped articles having a basis of a monocarboxylic acid ester of cellulose of a degree of substitution of at least 2.7, preferably 2.85 or more, are made by extruding a solution of the cellulose ester in an organic solvent through one or more shaping orifices into a coagulant consisting essentially of water and an organic ester which will form with water a homogeneous mixture containing at least 0.5 per cent of the ester at a temperature between 0 DEG  and 100 DEG  C. The cellulose ester may be a propionate, butyrate, acetate formate, acetate pripionate, acetate butyrate, or particularly a cellulose triacetate of acetyl value (as acetic acid) above 58.8 and preferably about 61.0 per cent or higher. The solvent for the cellulose ester may be acetic acid, acetone, ethylene chlorohydrin, dimethyl-sulphoxide or dimethyl-formamide. Chlorinated hydrocarbon, e.g. methylene chloride, ethylene chloride or chloroform, either alone or in admixture with a small proportion of an auxiliary solvent, are preferred, particularly methylene chloride, either alone or in a mixture containing also up to about 20 per cent by weight of a lower aliphatic alcohol such as methanol, ethanol, n-propanol, isopropanol or a butanol. The organic ester present in the coagulant is preferably a lower aliphatic ester, e.g. ethyl acetate, isopropyl acetate, isobutyl acetate or secondary butyl acetate, or ethylene glycol or diethylene glycol diacetate.  Ether esters may also be used, especially 2-methoxyethyl acetate, 2 - ethoxyethyl acetate, 2 - (2 - methoxyethoxy)-ethyl acetate and 2-(2-ethoxyethoxy)-ethyl acetate.  The proportion of organic ester in the coagulant may be 0.5-25 per cent by weight and the temperature of the coagulant may be between 0 DEG  and 100 DEG  C.  In an example, a solution of cellulose acetate of acetyl value 61.2 per cent (as acetic acid) in a 90/10 by weight methylene chloride/methanol solution is spun into an aqueous solution of 2-methoxyethyl acetate of 4.6 per cent by weight concentration at 24 DEG  C. contained in an open trough. The filaments are drawn through the trough for a distance of 90 cm. and withdrawn as a yarn at a rate of 50 metres per minute, washed with water and dried.

Title: Improvements relating to warp knitting machines
Inventor: PORTER ALAN WILLIAM HENRY
IPC: D04B27/00
Filed: 1955-06-21
Abstract: 794,918. Knitting-machines. F.N.F, MACHINERY MANUFACTURING CO., Ltd. June 11, 1956 [June 21, 1955], No. 17962/55. Class 74 (2). The warp yarns pass round a movable roller 6 in their passage from the warp beam to the tension-bar 8 of a warp machine, the roller being positively moved to increase or decrease the length of the path of the yarns in the event of undue decrease or increase in the tension of the yarns. The roller 6 is carried by a quadrant 12, 12a at each end, one of which is geared to the drive from an electric motor and both of which are mounted on a shaft 4 serving as a roller around which the yarns pass to the roller 6. The yarns further pass over a roller 7 to the tensionbar 8 mounted on spring cantilever arms 14 attached to a shaft 15. A toothed quadrant 16 is attached to shaft 15 and engages a pinion 17 to which is attached a finger 18. Normally slight fluctuations in tension of the yarns are accommodated by the arms 14 but undue increase or decrease in tension causes the bar 8 to rotate the shaft 15 against or under the action of a coil-spring 21 influencing shaft 15 through lever 19. Consequently quadrant 16 is rotated and also pinion 17 causing finger 18 to engage one or other switches 24, 31 controlling the electric motor which then rotates shaft 4 and quadrants 12, 12a in the appropriate direction whereby roller 6 is moved to increase or decrease the path of the yarns. On resumption of normal tension the finger 18 is returned to its central position.

Abstract: 576,016. Lubricating. PRESSED STEEL CO., Ltd., ROWLEDGE, E. G., and KITSON, J. W. Sept. 26, 1944, No. 18330. [Class 12 (iii)] The valves and upper portion of the cylinder of a compressor of a refrigerator unit are lubricated by metering lubricant through a gauze restrictor unit into, or adjacent to, the stream,of refrigerant vapour as the latter passes to the compressor whereby the lubricant is converted into a fine mist entrained in the refrigerant vapour. A hermetically closed unit is shown in which the lubricant is derived from an auxiliary sump 10 supplied by the overflow from themain bearing 12 of the direct-driven crankshaft C. Refrigerant vapour drawn in through a silencer 14 passes by a pipe 15 to a bore 38 formed in the cylinder block and leading to an open part 13 in a lapped valve plate 17 situated between a cylinder head 18 and the cylinder block. The refrigerant passes into the cylinder Y through an inlet chamber 24 and valve 27 and after compression is discharged through a valve 29 to pass to the condenser through a delivery chamber 23, a silencer 26 and pipe 28. In the bore 38 is inserted a metering gauze restrictor comprising as shown in Fig. 3, a gauze cylinder 34 and blanking foil 35 held in place by an inner spring expanding clip 36; a passage from the auxiliary sump 10 opens on to the periphery of this gauze restrictor unit whereby the lubricant is entrained as a fine mist through the gauze by the flow of the refrigerant vapour on its passage towards the compressor so to lubricate the valves and upper portion of the cylinder. The refrigerant on its return from the condenser* and evaporator is fed to a separating chamber 30 warmed by the motor heat in which any lubricant carried by the vapour may settle and fall to the main sump S. In the modification shown in Fig. 7 the lubricant from the auxiliary sump 10 passes through a gauze plate 44, held in place by a blanking plate 45, to a capillary groove 53 formed on the valve plate and serving to direct the lubricant to the inlet valve opening 27 where the lubricant is entrained as a mist by the flow of the refrigerant vapour.
