Abstract: 971,410. Film stretching apparatus. J. C. NASH. Dec. 3, 1962 [Sept. 5, 1962], No. 45474/62 Heading B5B. [Also in Division D1] In a tenter frame for transversely stretching a moving film, opposite sides of the film are gripped by tenter clips, spaced apart in the transverse direction of stretching, which move in unison from a film receiving region to a film discharging region along diverging paths having complementary smooth oppositely curved contours over at least a part of each path. The curved path may be an hour glass curve, as in Fig. 1, or a reverse curve, as in Fig. 11. In operation, rotation of tenter chains 110, 111 in rail members 72, 73 carries the film to be stretched from the film receiving region between sprockets 126, 127 to the film discharging region between sprockets 120, 121. Cams 120A, 121A engage upstanding arms 130 (Fig. 8) of the pivoted jaws 90 of the tenter clip chains causing their lower edges 91 to swing away from bases 81 and discharge the film. At the film receiving region cams 126A, 127A engage arms 130 to pivot jaws 90 away from bases 81, and as the arms 130 move in the direction of the arrows A, B, they discharge cams 126A, 127A to release pivoted jaws 90 to the action of gravity to grip the film between bases 81 and lower edges 91. Rotation of hand wheels 22, 22A, 22B &c. secured to the shafts 21, 21A, 21B which each have screw-threads, e.g. 37, 38 of shaft 21, causes the respective saddles 40 (not shown), 40A, 40B &c. to slide upon cross-members 17, 17A, 17B &c. whereby the rail members 65, 65A, 65B &c. and their tenter clip tracks are moved in relation to one another to provide an accurately controlled preselected path of movement for the respective tenter clip chains 110, 111.

Title: Improvements in and relating to ovens for heating thermoplastic filaments
Inventor: KALAJA EERO
IPC: D01D10/04
Filed: 1967-10-24
Abstract: 1,136,860. Heating oven for thermoplastic filaments. SPINNER OSAKEYHTIO. 24 Oct., 1967 [22 Sept., 1967], No. 48265/67. Heading B5B. A heating oven for thermoplastic filaments, consists of an elongated body with insulation 6 and in which a longitudinal channel 9 has been formed for passage of the filaments, a heating element 7 being placed on the bottom of this channel, the said heating elements consisting of a tube constituting the bottom of the channel and through which a heating fluid is conducted. As shown in Fig. 3, grooves may be provided on the surface of the tube 7 for the passage of the filaments 10. Heating fluid is supplied from insulated pipe 2 and preferably passes upwardly through the vertically disposed tube 7, and returns to insulated pipe 4. As shown, the bottom tube 7 of channel 9 forms a grooved friction surface and is shaped slightly convexed in the longitudinal direction to ensure positive contact between the filament and the tube 7 over the entire length of the latter. The filaments 10 are suitably heated to about 150‹ to 250‹ C., so that they reach their plastic condition. Known heat transfer media are used. The filaments may alternatively be arranged to pass through the oven in the channel 9 in such manner that they do not touch the heating surface. In this case the temperature of the heating fluid flowing in the heating tube must be considerably higher, even up to 400‹ C. If desired, the cross-sectional shape of the heating tube may be square, rectangular, circular, or oval. When the filament does not touch the heating surface, a tube of U-shaped cross-section surrounding the channel 9 is especially advantageous. The channel 9 in the oven may be provided with a cover if desired. The use of a heat transfer fluid in place of the conventional electrical heating has the advantage that the heat is completely uniformly distributed over the length of the oven. Filaments may be heated, e.g. to curl them, using the apparatus of the invention.

[Also in Division F1] A system for supplying cooled water to a cooling apparatus, e.g. an aviator's cooled garment, comprises vessels 13 and 14, which are charged approximately half-full with water and solid carbon dioxide. When the solid carbon dioxide becomes ice-covered, and the rate at which gas is given off slows down, lids 15 and 16 are put on the vessels and gas pressure develops above the liquid. A valve 25 controls vent ports 23, 24 communicating with vessels 13, 14, respectively, the valve being controlled by a float 26 in a chamber 22 connected to vessel 14. When vessel 14 is full, valve 25 closes port 24, and the gas pressure in vessel 14 acts to keep port 24 closed and forces the cooled water through pipe 29, valve 35, pipe 31, cooling apparatus 33, pipe 32, valve 37, and pipe 28 to vessel 13, where it is re-cooled. When vessel 14 is sufficiently empty, float 26 falls and valve 25 vents vessel 14 and closes port 23, vessel 13 then discharging through valve 34 to apparatus 33 and back through valve 36 to vessel 14. This cycle continues until all of the solid carbon dioxide has dissociated. Safety valves 17 and 18 are provided. The apparatus is enclosed in a heat-insulating casing 11, 12.
