Title: Dispensing closure with spout
IPC: B65D47/30
Filed: 1974-09-17
Abstract: 1466436 Dispensing closure; child resistant POLYTOP CORP 17 Sept 1974 40439/74 Heading B8T A spout 14 is rotatably mounted on a cap 12 by trunnions on the base 56 of the spout which are located in bearings in the cap, and the spout has a passage 68 extending therethrough which is in alignment with an opening 34 in the cap in the open position (Fig. 4), but in the closed position, when the spout is within a groove 36 in the cap skirt 18, the opening 34 is sealed off. In the closed position, the spout 14 is snapped over the bump 50 and the then visible surface of the spout is formed to blend in with the skirt surface which has lines 20 and circumferential grooves 96 thereon. The bottom of the skirt 18 fits in a groove 90 around the base of the container neck 86 so that the spout lip cannot be grasped to rotate the spout until the closure is rotated on the container neck to align the spout with a groove 94 extending down the side of the container 84. The projection 66 on the base 56 of the spout deforms a portion of the cap top 16 as the spout is rotated, thus holding the spout in the open position. A tube may extend from the cylindrical wall 26 to the bottom of the container and/or other pump elements may be incorporated, within or separate from the closure. The container may have deformable walls.

Title: A method of producing soluble nitration products of lignin
IPC: C08H5/02
Filed: 1959-12-03
Abstract: Soluble nitration products of lignin are produced by contacting nitric acid with lignin (obtained by hydrolysis of cellulosic material such as wood by mineral acid without the application of heat) in suspension in a water immiscible organic liquid which is inert towards said nitric acid by intimately admixing said lignin suspension with nitric acid.  The latter preferably has a specific gravity not substantially less than 1,48 and the reaction is preferably effected at temperatures not exceeding 28 DEG C.  The nitric acid may be introduced in admixture with the dispersant. Suitable organic liquids are carbon tetrachloride, carbon disulphide and methylene dichloride. Suitable ratios by weight of lignin to nitric acid are 100 to 30, 100 to 40 or in the range 100 to 70 to 100 to 80.

The kinematic drive means comprises a motor 11 driven gear train 26-31 which divides at the reversing gearing 40, 41 and through another branch 47-53 the workhead spindle 6. The cradle 3 and spindle 6 are both rotated by worm 8 wheel drives 32, 34 and 33, 35 respectively. The set-over rotation of the cradle 3 is achieved by moving the worm 34 axially to partially rotate the cradle. The cradle is also reciprocably rotated by means of the reversing gearing 40, 41 during the grinding of a tooth. The worm 34 is moved axially by a crank mechanism (54-57) (Figs. 6, 7, not shown) having adjustable stops (66), (67) to limit the travel. The crank (57) is rotated by a pressure cylinder driving a rack which engages a pinion connected to the crank. The setting-over of the disc tool is achieved by oppositely directed pressure cylinders (14) (Fig. 2, not shown) which respectively hold the disc tool 4 in each of its two end positions against adjustable cam stops (19), (10) (Fig. 4, not shown) which include setting dials (24), (25). The workpiece 7 may have pre-cut tooth spaces before grinding, or be a solid gear blank. In the machining operation one side of all the teeth are ground, the set-over movements are made, and all the other sides are ground.
