Abstract: 1,210,656. Coated foams. DUNLOP CO. Ltd. 6 June, 1968 [7 June, 1967], No. 26256/ 67. Heading B2E. [Also in Divsion C3] A composite polyurethane foam material is produced by impregnating an open-cell polyurethane foam with a monomer or monomers selected from olefinically-unsaturated hydrocarbon monomers, halogen derivatives thereof, and acrylonitrile, and polymerising the monomer(s) within the foam to form a deposit of polymer within the pores of the foam. The foam may be a skeletal or reticulated foam. The polymerisation may be carried out by an irradiation technique, an emulsion polymerisation technique, or in the presence of a peroxide catalyst. The composite material may be subsequently compressed and a further monomer may be graft polymerised on to the polymer deposit within the pores of the foam. The hydrocarbon monomers may be ethylene, propylene, butene-1 and 'butene-2; butadiene; pentadienes and styrene; halogen derivatives, e.g. vinyl chloride; and mixtures thereof. The monomer(s) may be used in liquid or gaseous state. In Example I, the foam is enclosed in a chamber, a mixture of hydrogen and oxygen introduced to a final absolute pressure of 0.8 atmosphere and, the mixture ignited by means of a sparking plug; the foam is subsequently placed in gaseous butadiene and subjected to high energy ionising radiation. Example 2 describes foam immersed in acrylonitrile, drained and irradiated; and also foam irradiated while immersed in a solution of acrylonitrile in benzene. Example 3 describes foam immersed in styrene, drained and irradiated; and also foam irradiated while immersed in a solution of styrene in cyclohexanone.

Title: Yarn winding machine
IPC: B65H67/08
Filed: 1962-07-10
Abstract: 960,197. Winding yarns; thread guides. H. GLASTRA. July 10, 1962 [July 13, 1961]; No. 26559/62. Headings DID and D1J. Yarn 15 is wound from a supply 1 on to a cone 2 via a tube 4. A suction-tube 5 is bent partly around a knotter 12 and is connected to a side wall of the tube 4. The inside bend of the tube 5 is formed with a narrow cut 14 that joins a narrow cut 13 in the tube 4 at a point below the knotter 12. The tube 4 is slidable on an inner tube 6 having a tapering nozzle 8 at its lower end, a slotted closure plate 9 at its upper end, and a lateral opening 10 which, at the setting shown, is aligned with the suction tube 5. The slot in the closure plate 9 extends into the lateral opening 10. When the yarn 15 breaks a yarn detector in the form of a feeler or scanner (not shown) swings a slub catcher 16 out of its normal position and then moves the cone 2 against the nozzle 8. The rotation of the cone 2 is reversed and the loose end of the yarn is drawn into the nozzle 8 and thence into the tube 5 from whence it escapes via the cut 14 so that it is laid across the knotter 12. Similarly the yarn end from the supply 1 is drawn down the tube 4 and into the tube 5 from whence it escapes via the narrow cuts 13, 14 so that it also is laid across the knotter 12. The knotter 12 then operates, the suction in the tube 5 is cut off and winding is re-commenced. When a new supply spool 1 is fitted, the tube 4 is raised to surround the spool 1, Fig, 3. This movement blocks the lateral opening 10 and, with the closure plate 9 in position, ensures maximum suction in the tube 4 for the purpose of unwinding the free end of the yarn from the new spool 1 and supply it to the knotter 12.

Title: Improvements relating to expanding rings, bracelets, arm bands and the like
Inventor: CURRY FRANCIS JOSEPH
IPC: A44C5/08
Filed: 1948-10-16
Abstract: 656,809. Bracelets. JARRETT, RAINSFORD & LAUGHTON, Ltd. Oct. 16, 1948, No. 26954. [Class 43] In a spring-link expanding bracelet each inner link, consisting of two interconnected, strip-metal loops 10, 11 enclosing a spring 14, is housed in an outer sleeve 15, which is open at one end 16 but has abutment means 18 at the other so positioned that they prevent the passage of one loop through this end but allow the passage of the other, outward movement of which is arrested by the spring when fully compressed. The identical loops 10, 11, preferably of D section strip, are each gapped towards one end at 12 and 13 respectively. To assemble the parts, a helical spring 14 is placed in one loop, e.g. 10, with one end abutting one end bar of the loop, and then the other loop 11 is engaged by means of its gap 13 with the free part of the loop 10, and is swung into alignment with the latter so that, when the spring 14 expands, the loops, form a box. This assembly is inserted into a sleeve 15 through its open end 16; the end bar of one loop, e.g. 10, is then pulled against the spring pressure through an oblong opening 17 in the other end of the sleeve, the end bar of the other loop 11 being held back by the abutment 18, formed by the bent-over material which borders the edges of the longer sides of the opening 17. The loop 11 of another link assembly is now hooked over the projecting end bar of the first loop 10, and an outer sleeve 15 is slid over this second link assembly. When the required length has been built up, the ends may be joined as follows. The loop 10 of the sleeve 15 at one end of the length is pulled through its associated opening 17 and another loop 10a is hooked into it; the loop 11 projecting from the open end 16 of the sleeve 15 at the other end of the length is also supplied with another loop 11a. A sleeve 15a, with its abutments 18 temporarily straightened up, is pushed over the loop 11a, a spring is inserted in said loop, which; is then hooked into the loop 10a, the sleeve 15a is slid into its correct position and its abutments 18 are bent over. By arranging the loops 10, 11 so that their gaps 12, 13 approach as the link is expanded, the fully compressed spring 14 will stop expansion before the gap in the loop which is slidable through the opening 17 is exposed; the abutments 18 prevent the gap in the other loop from being exposed.
