Abstract: 717,507. Shaping bottle caps &c. from metal foil. FORDS (FINSBURY), Ltd, Oct. 7, 1952 [Oct. 8, 1951], No. 23375/51. Class 100 (2). Forming cupped metal articles.-A die for a press-tool for forming cupped metal articles, e.g. bottle caps, from metal foil comprises a spring- loaded pressure ring 42 within the die ring 33 adapted to prevent the formed metal article from sticking within the die ring and which is divided into segments, Fig. 3, each being provided with means for tilting the segment as the tools separate, thus preventing the formed article sticking by an oil film to the outer surface of the ring. The machine which is otherwise similar to that described in Specification 667,301 comprises die parts 2 and 3. Die part 3 comprises a shearing ring 12 secured to a boss 13 on the casing wall 1. A disc 9 secured to the other end of the boss carries a bolt 19 on which slides a spring-loaded ring 23 connected by a number of pins 22 to an ejector ring 21 adapted to eject the formed cap from the shearing ring. The disc 9 also supports a cylindrical forming member 17 having a lettered embossing plate 18. The other die part comprises a cylindrical guide casing 27 in which a carriage 28 is reciprocated by a crank and connecting-rod 29. A cup-shaped shearing member 33 fixed to the carriage 28 co-operates with the shearing ring 12 and the forming member 17 first to cut out a blank from the strip of foil 4 and then to form it into a cup over the member 17. A resilient buffer 38 held in a cup 37 forces the centre part of the cap against the embossing plate 18 to impress the lettering thereon. Inside the member 33 slides the segmented pressure ring 42 preventing the cap sticking inside this member and loaded to the projecting position by a spring 43 bearing on an internal flange 44. The flange 44 is deformed at one end of each segment as shown at 47 in Fig. 3, this being effected for instance by cutting at 48 and bending. As the carriage 28 moves away from the other die part 3 the overhanging shoulder of the cup 37 engages the parts 47 of the flanges of the segments and causes each segment to tilt so that the formed cap is engaged only by a number of points thus preventing sticking due to the formation of a continuous oil film. In addition to the bent end 47 the flange may be formed with a rib 49 by upsetting the material of the flange or by soldering, brazing or integrally casting the rib on. The spring 43 will bear against this rib. Specification 646,552 also is referred to.

Abstract: 1,267,520. Corrugating. KOPPY TOOL CORP. 8 May, 1969, No. 23403/69. Heading B3E. [Also in Division F2] A tubular member having controlled collapsing characteristics is made by forming a series of annular ridges 24-32 in the wall of a metal tube 10 and applying a longitudinal force at opposite ends of the series of ridges, the force being sufficient to shorten the tube and enlarge ridges radially. The annular ridges are formed by a plurality of die sections each comprising a series of laminated sections 16-23 joined together to form a die face 14. The inner surface of the tube 10 is supported opposite the surface engaged by the die sections. The dies are preferably shaped so that the major diameter of each successive ridge is progressively reduced from one end of the tube to the other. The laminated sections may also be progressively reduced in thickness. The blank is then placed in a die 38 and the axially compressive force is applied so that the ridges 24-32 progressively and radially enlarge until the ridge peaks reach the internal diameter of the die 38.

Title: Dewatering thermoplastic resinous materials
IPC: C08F6/14
Filed: 1949-09-19
Abstract: Water is removed from an unrestrained selfsustaining mass containing water and a thermoplastic resinous precipitated irreversible colloid by heating the mixture in the presence of sufficient water vapour to prevent substantial evaporation of the water in the mass and having a wet bulb temperature of at least the agglomeration temperature of the resin to cause the resin to agglomerate and thereby force a substantial portion of the water in a liquid state from the resin. "Agglomeration temperature" is the temperature at which the resin particles tend to fuse. Resins which may be treated include copolymers of dienes and vinyl aromatic compounds, vinyl chloride polymers and copolymers, e.g. with dialkyl maleates and fumarates, and acrylonitrile-styrene copolymers.  If the slurry resulting from the precipitated emulsion contains too much water to be self-sustaining, excess water is removed, e.g. by filtration, below the agglomeration temperature until the mixture can be shaped into a self-sustaining mass.  This shaping may be effected by forcing the filter cake through a grid to form pellets which drop on to an endless belt to produce a layer about 4 inches thick.  This is then heated in a chamber through which flows moist air of the required temperature. The mass may also be heated by infra-red rays or high-frequency electricity and the moist air may also have to be used under pressure.
