Patent ES-291037-A1 (ES)
Title: Method and apparatus for controlling temperature of the workpiece during rolling
IPC: B21B37/74
Filed: 1963-08-23
Abstract: A method of rolling a hot elongated workpiece in a rolling mill train comprises generating a signal representing a desired predetermined temperature for the workpiece, generating a second signal corresponding to the difference between the actual and desired temperature, and varying the speed of the train to vary the heat losses by conduction and radiation to maintain the workpiece temperature substantially at the desired value. An increase, for example, in the speed of the train results in less heat being lost by conduction and radiation, due to the shorter time available to the workpiece for losing heat, and an increased input of heat from the rolls as they roll the workpiece. The temperature of a strip S is measured by pyrometers 30, 31, and 32, whose outputs are fed into an analogue computer which controls the motors 21 of rolling stands 11-16 and also cold water sprays 27 and coiler motors 28. The speeds of the stands are controlled so that the strip temperatures measured by the pyrometers reach predetermined values. An X-ray thickness gauge 33 may be used to give automatic thickness control of the strip. The screwdown for the stands is by means of a motor-driven worm 39 and which actuated a screw 37, the worm being axially movable by a high-speed piston cylinder assembly 42. In order to permit coiling of the free end of the workpiece, the rolling speed of the train is gradually increased from a suitable value. Specifications 942,128 and 952,941 are referred to.

Title: Method and machine for the manufacture of tanks from fibre reinforced plastic material
IPC: B29C53/80
Filed: 1967-04-29
Abstract: A method of making a hollow tank from rovings 3 of plastics soaked fibrous material, e.g. glass, comprises winding the roving about a rotating core 1 by traversing the roving to lay it helically on the cylindrical part of the core, and, at the ends of the core, discontinuing the traverse and while the rotation of the core continues, effecting radial movement of the roving to lay it over the ends of the core. The rovings are laid over the ends of the cores in a starshaped formation, e.g. a five pointed star as shown in Fig. 7, and each successive star is circumferentially displaced from the preceeding star until the core is covered. In Fig. 1 the core 1 on a spindle 2 is rotated by an electric motor 12, gear-box 13 and gearing 14, 15 which also drives a control mechanism comprising a stretchable belt 50 having an abutment 34 which acts on two switches 32, 33. The roving guide 4 is mounted on the piston rod 3 of a fluid operated cylinder 8 situated on a carriage 5 reciprocated by a chain drive 19 driven by a chain 26 from a sprocket 25 driven from the motor 12 by way of a coupling 17. In use, in relation to Fig. 1, the roving guide 4 is withdrawn by the piston rod 3 and, with the core 1 rotating, is traversed to the left. At the end of the core the carriage operates a switch 131 that actuates the coupling 17 to disconnect the traverse to the carriage and, with the core still rotating the abutment 34 operates the switch 32 to cause the cylinder 8 to move the roving radially of the core to lay it over the end of the core (Fig. 4, not shown). The switch 33 is then operated by the abutment 34 to cause the roving guide to withdraw radially so that the roving is then, due to the continued rotation of the core, on the other side of the core, the switch 33 also actuates the coupling 17 so that traverse of the carriage is restarted and the carriage 5 moves to the right to lay the roving on the cylindrical part of the core until the other end is reached whereupon the procedure is repeated. The controls are operable to form various configurations of rovings and embodiments are described wherein the core is either removed from the tank or left to form a lining.

Title: Method and Apparatus for Making Seed Tape
IPC: B65B9/06
Filed: 1967-12-05
Abstract: In manufacturing a seed tape from a tape of water soluble material the tape is initially moistened along at least one edge margin on one side of the tape to make it slightly tacky, seeds are deposited on to the tape at spaced intervals, the tape is closed on itself and adhered to itself by its own tackiness to encapsulate the seeds therein. The tape may be moistened over its whole surface so that each seed adheres to it. In the arrangement shown tape 10 of polyethylene oxide is drawn from reel 11 over a roller 26 and passes through a moistening device 27 and thence through a trough shaped cupping member 35 which folds the tape into a V formation. The tape in V form then passes beneath a dispensing station 40 which drops seeds at spaced intervals on to the tape. The tape then passes through another shaping member 41 which is more U-shaped than V-shaped and then between discs 12, 13 which seal the edges of the tape together. Discs 12, 13 also serve as means for pulling the tape through the apparatus and a counter 47a may be associated with one of the discs for measuring the length of completed tape. From the discs 12 and 13 the finished tape 14 is taken-up on a core 48. The dispensing means 40 consists of a rotating head 50 from which project a number of arms 51 each having at its end a nozzle 52 which is changeable. The arms are connected to suction means as they pass over and dip into a hopper 53 containing seeds so that each nozzle 52 picks up a seed and carries it around until it is over the tape 40. At this position the arm 51 is connected to atmosphere so that the seed is released on to the web. Between the seed dropping position and the seed picking-up position, the arm 51 is connected to a pressure source to clear the nozzle. The hopper 53 is vibrated to prevent formation of furrows in the seeds therein.
