Title: Improvements in and relating to a package for packing elongated objects such as supports provided with textile threads
IPC: B65D5/50
Filed: 1965-11-05
Abstract: 1,121,549. Packaging thread etc.; cartons. PAPETERIES RENE SIBILLE. 5 Nov., 1965 [14 Jan., 1965], No. 46946/65. Headings B8C and B8P. The ends of fragile elongated objects, such as spools of thread, are secured between centring elements, on two grids D, and are thus held apart in a carton C. In the preferred form the centring elements, which are located at the intersections of the bars of the grid, are frustoconical in form, having slots for increased resilience, and fit inside axial bores in the ends of the spools. The ends of the bars 1, 2 of the grid are linked by a frame 3, and both bars and frame may have strengthening ribs along their lengths. The apertures in the upper grid facilitate manual alignment of the objects. The pairs of grids may be linked rigidly by ties. If spools of thread are to be packed retaining lugs (12a), Fig. 3 (not shown), on the centring elements (0) may coact with flanges (12) on the end of each spool to facilitate unwinding of the thread from the spool. In a further embodiment the grids are provided with double centring elements, whereby a plurality of rows of objects may be stacked. The centring elements may be shaped so as to fit outside the ends of the objects.

Filed: 1968-10-03
Abstract: 1,248,917. Angular bending. H. J. STEEL. 3 Oct., 1968 [12 Oct., 1967], No. 47051/68. Heading B3E. An apparatus for cold bending tubes com prises a grooved forming roller, drive means for rotating said roller, a leading clamp connected to said roller for securing the leading pipe portion said clamp rotating with said roller, a linearly movable trailing clamp for securing the trailing pipe portion and a mechanical linkage other than said drive means connecting said clamps and disposed to maintain the distance between said clamps along the bending path constant to thereby maintain a constant length of the outer bend surface of said tube. The base 1 supports guides 2 for a slidable carriage 3 carrying the trailing clamp 4. The grooved roller 6 provided with a leading clamp 10 is rotated by rack and pinion gearing 13, 14, Fig. 3, driven by hydraulic cylinders 16. A grooved supporting shoe 18 and a grooved pressure die 19 support the pipe walls at the entrance to the roller 6. As the pipe is bent around the roller the distance be-  tween the clamps 4 and 10 is kept constant by means of a pair of chains 22 attached to the clamps. If desired the load on the chains may be eased by a compressed air cylinder 25 attached to the carriage 3 and after forming this cylinder is used to retract the carriage. To prevent scoring of the pipe the grooved pressure die is attached to the carriage directly or through toggle mechanism so as to move with the pipe.

Abstract: 1279125 Flavouring tobacco HAARMANN & REIMER GmbH 25 Sept 1969 [30 Sept 1968] 47165/69 Heading A2C The smoke flavour and aroma of a tobacco material or a tobacco substitute, are improved by the addition of aromatic substances obtained by fermentation and extraction of a vegetable chlorophyll-containing non-tobacco leaf material. The non-tobacco material may be fermented before extraction, or the extract may be obtained first and subsequently fermented. Leaves of various plants are mentioned as being suitable, including chestnut, horse chestnut and stinging nettle. When leaves of more than one kind of plant are used they may be processed together to obtain the extract or individually to produce extracts which are subsequently mixed in desired proportions. The smoking material may be treated with the extract by immersion or spray. Various processes for fermenting the leaves and obtaining the extracts are described, and according to one example chestnut leaves are stored for 2 weeks at 50C and 80% relative humidity and then subjected to an extraction process using steam distillation and ether. The extract, after removal of the ether, is dissolved in ethanol and sprayed on to tobacco in an amount such that after evaporation of the solvent the proportion of extract to dry weight of tobacco is 0.001%.

Abstract: 1357155 Removing electrical contact pin retaining clips from connectors ITT INDUSTRIES Inc 28 Oct 1971 [30 Oct 1970] 50086/71 Heading B4C A tool for removing a tubular electrical contact pin retaining clip 162 from a bore 170 of an electrical connector body, comprises (1) an elongate rod 122 having at its forward end four axially extending fingers (134) (Fig. 2, not shown) which together define a tapered nose 144, a rearwardly facing shoulder 148, a substantially cylindrical portion 138 and a rearwardly tapering surface 136, and (2) an elongate tubular member 46 which is slidable relative to the rod to engage the rearwardly tapering surface 136 so as to deform the fingers to the condition of Fig. 7. The tool further includes a nut 14 threadedly mounted on the rod and connected via a metal retaining ring 45 to the rear end of the member 46. A sleeve 82 is slidably mounted on the member 46 and includes inwardly biased spring tabs 92, 94. Removal of the clip is achieved as followsfirstly the sleeve 82 is positioned such that tab 94 extends into notch 74 in member 46. Then the rod 122 is moved rearwardly relative to the member by rotating the nut 14 until the shoulder 148 abuts the forward edge of sleeve 82. The tool is then introduced into the bore until the nose 144 abuts insulator 168 (Fig. 4). The tubular member 46 is rotated through 90 degrees to remove tab 94 from notch 74 and continued forward movement of the rod 122 and the tubular member 46 relative to the sleeve 82 is then permitted. The nose 144 passes through the clip by virtue of deformation of the fingers so that the position of Fig. 6 is reached. Appropriate rotation of the nut 14 will cause the tubular member 46 to move forwardly relative to the rod 122, to engage the surface 136 and cause the fingers to be forced together (Fig. 7). The clip will thus be deformed so as to permit its removal from the bore (the clip is provided with slots 192 to permit such deformation). Also a groove 58 at the forward end of the tubular member 46 will engage the rearward end of the clip.  A pull on the tool, assisted by action of spring 112, will cause the clip to be withdrawn completely into the sleeve (Fig. 8, not shown). Further pulling on the tool, after tab 92 extends into groove 52 will effect withdrawal of the whole tool from the bore.
