Abstract: 484,252. Closures for bottles. INTER-SEAL CORPORATION. Aug. 28, 1936, No. 13255/37. Convention -date, Nov. 30, 1935. Divided out of 475,439 under which a Specification was laid open to inspection under Sect. 91 of the Acts, March 1, 1937. [Classes 125 (i) and 125 (iii)] A closure element 31 for the discharge orifice of a bottle &c. is secured by a cap 43, Fig. 2, having separate depending portions 56 which are weakened transversely at say lines 58 so that when the lower ends 57 of the portions 56 are secured to the bottle any attempt to remove the cap in order to gain access to the contents of the bottle necessitates rupture at the points 58 so leaving the parts 57 secured to the bottle as visible evidence of its opening. As shown, the parts 57 are provided with a hook 61 or a head which is forced into an undercut groove 37 on the bottle or a part thereof; the cap is formed from a sheet metal blank of the form shown in Fig. 8, by operations consisting of simple bending, and it is provided with tear-off tabs 59, the body part being notched at the points 60 where the tabs make junction with the body, and the latter being furnished with slits or weakened lines 55 to assist the operation of removal. The groove 37 is formed between a main nozzle portion 27, Fig. 2, either separate from or integral with the neck of the bottle, and a secondary ring portion 28, the latter and the part 27 being, if desired, united together by firing a coating of glazing material; the parts 27, 28, if separate from the bottle, are secured thereto by means of a ferrule 24, the lower part of the ferrule being secured to a flange 16 on the bottle neck and the upper part of the ferrule being turned into the groove 37 ; a number of openings in the upper part of the ferrule facilitate this latter operation, and such openings may each accommodate a projection 49 on the ring 28 this being of frangible material so that an illicit attempt to remove the ferrule will become obvious by breakage of one or more of the projections. As shown in Fig. 2, the bottle is furnished with parts 17, 21, 51 constituting the elements of the non-refillable device of Specification. Specification 475,439 is referred to. The Specification as open to inspection under Sect. 91 refers to a modification in which the cap 43, Fig. 1 (Cancelled), is formed without lugs and is further secured to the nozzle by rolling the metal into screw threads 30 formed on the latter, and in this form the weakening line 46 is formed completely round the cap. This subject-matter does not appear in the Specification as accepted.

Title: Roll with means for removing longitudinal curvature
IPC: D06C15/08
Filed: 1966-03-30
Abstract: 1,099,960. Rollers. MOUNT HOPE MACHINERY Ltd. March 30, 1966 [July 19, 1965), No. 13982/66. Addition to 979,018. Heading F2U. In a roll for a paper-making machine, a hard rubber or fibre glass sleeve 24 is rotatably mounted by spools 14, 18, and bearings 161-164 upon a stationary hollow axle 12 which is initially bowed to a preselected curvature by a tension rod 34 welded to an abutment 42 in the axle, nuts 40 on each end to an abutment 42 in the axle, nuts 40 on each end of the rod allowing individual tensioning of each half of the rod, and hence individual setting of the curvature of each half of the axle on either side of the abutment 42, so that the resultant force of the axle weight and load elastically deflects the roll to a longitudinally straight configuration. Water-tight end-caps 26 on the roll protect the bearings 161-164. The axle ends are supported in plain cylindrical bearings or, as shown, spherical elements 28. In Figs. 2-5 (not shown), the sleeve (24) is supported by four spools (14), (18), and five bearings (161-165), and the hollow axle is formed with two spaced intermediate abutments (48), (50), pairs of tension rods (56), (58), symmetrically spaced about the vertical plane of curvature, extending between the end walls (37) and the respective nearer abutment. These pairs of rods may also then be used to correct residual curvature in a plane at right-angles to the principal plane of curvature due to manufacturing tolerances. A fifth tension rod (52) extends from one end wall (37) freely through the first abutment to the second abutment to compress that section of the axle between the two abutments. Each pair of tension rods (56), (58) may be replaced by a single hollow tube, Fig. 6 (not shown), telescopically receiving the longer tension rod. Since the central axle portion requires most bending movement, it may be permanently deformed with an upward bend, or the hollow tube may be subjected to compression, Fig. 7 (not shown), to reduce the bending moment applied to the respective endmost section of the axle by the interior rod. In Fig. 8 (not shown), two tension rods only are used, extending the whole length of the axle from the upper circumferential part of one end wall, passing freely through a respective first abutment and welded to the lowermost circumferential part of the second abutment, and then extending to the uppermost part of the second end wall.
