Patent GB-455782-A (GB)
Title: Improvements in the treatment of textile materials
IPC: D06M15/17
Filed: 1935-04-27
Abstract: A scroop finish is imparted to artificial silk fabric by depositing thereon a small proportion of a water-insoluble higher aliphatic ester of a polyhydric alcohol or of a higher acyclic monohydric alcohol.  The ester is preferably deposited on the fabric from a solution in an organic solvent, e.g. benzene or carbon tetrachloride, the weight of the deposit being 0,05--2,5 per cent. of the weight of the fabric; or from an aqueous dispersion, together with glue and a wetting agent which does not contain a long aliphatic chain, e.g. alkyl naphthalene sulphonic acid.  The higher fatty acids employed contain at least 8 carbon atoms, e.g. tri-stearin, coconut oil, palm kernel oil or the higher saturated fatty acid glycerides contained therein, e.g. tri-laurin, tri-palmitin and tri-myristin; glycol di-stearate and di-ethylene glycol di-stearate are also suitable. Suitable higher acyclic monohydric alcohols are those containing at least 8 carbon atoms, e.g. lauryl, stearyl, and cetyl alcohols.  In an example, 100 gms. of beef fat or spermaceti wax are melted and poured into 100 ccs. water containing 50 gms. glue and 10 gms. of the wetting-agent sold under the Registered Trade Mark "Nekal A." and stirred; the whole is then mechanically emulsified and made up to 1 litre with water.  A dyed fabric containing cellulose acetate yarns is immersed in a 2,5 per cent solution of the above emulsion, hydroextracted so that it retains 40 per cent of its weight of liquid, dried and finished.  Specifications 407,449; 424,683, 424,752, 424,830, and 424,879, [all in Group IX], are referred to.

Abstract: 691,921. Drawing. BOLTON & SONS, Ltd., T. May 23, 1951 [May 26, 1950], No. 13240/50. Class 83 (iv). In a tube or bar drawing machine the work is fed to the dies or to a push pointer by gripping jaws. A pair of gripping jaws 17 for feeding tubular work to a push pointer are mounted on a cross-head 11 on the forward end of a guide tube 12 sliding in a fixed sleeve 13 forming part of the back bench. The jaws 17 are interconnected by toothed quadrants 16 and the upper jaw is actuated through an arm 14 by a hydraulic or pneumatic ram 22. The cross-head 11 is guided by rods 24, 27 sliding in fixed brackets 23, 25, and forward movement of the cross-head 11 is resisted by an adjustable friction gripper 26 engaging the guide rod 27 and controlling the pressure with which the grippers 17 engage the work. Movement of the arm 14 is limited by a stop 19 and the closure of the grippers is limited by a stop 18 to prevent distortion of thin-walled tubes. In operation, the initial movement of the ram 22 moves the jaws 17 to grip the work and then advances the jaws to feed the work. The jaws 17 may have interchangeable grippers for different sizes of tubes, and several sets may be assembled together for feeding a number of tubes simultaneously.

Title: Apparatus for automatically feeding a parcelling machine through an automatically loaded and unloaded package magazine
IPC: B65B35/24
Filed: 1968-03-19
Abstract: 1,212,407. Endless conveyers for cigarette packages. AMF Inc. 19 March, 1968 [21 March, 1967], No. 13251/68. Heading B8A. Packages 11 normally fed from a packaging machine 1 to a pneumatic conveyer conduit 3 leading to a parcelling machine (2) (Fig. 1, not shown), are fed by a belt conveyer 18 to an endless conveyer 6 constituting a storage magazine, when the parcelling machine (2) is inoperative. When the latter becomes operational again, the packages are fed from the conveyer 6 to a conduit 24 which also leads to the parcelling machine (2) in parallel with the flow which at the same time recommences in the conduit 3. A stop 21 normally closes entry to the conveyer 18. When the stop 21 is released an associated valve closes entry to the conduit 3. Packages 11 are fed from the conveyer 18 into the conveyer 6 when an empty carrier 10 of the latter conveyer is in correct alignment. This is effected by the action of a switch 53 on a shaft 30 (Fig. 5) geared to the drive shaft 109 of the conveyer 6. A switch 56 (Fig. 3) senses that the carrier 10 is empty. When the carrier 10 is filled, a switch 22 (Fig. 2) is operated. This releases a brake 38 and engages a clutch 32 in the drive between a motor 29 and the shaft 109. A step-by-step motion for the conveyer 6 is derived from ratchet gearing 36. On restarting of the parcelling machine (2) clutches 43 and 45 are automatically operated in respective opposite senses so as to reverse the direction of drive of the shaft 109 (if clutch 43 is engaged, due to an idler pinion 41, the shaft 109 rotates in the same direction as that of shaft 33, otherwise clutch 45 is engaged and the drive is reversed between shafts 33 and 109). A switch 54 establishes that a full carrier is aligned with an output channel 23 leading to the conduit 24, and initiates the movement of an endless chain 26 carrying pushers 28 which engage the packages 11 and discharge them into the channel 23. A number of machines 1 (Fig. 1, not shown) may be connected up in parallel to a single parcelling machine (2).
