Title: Shrink packaging method and apparatus
IPC: B65B53/06
Filed: 1965-12-29
Abstract: 1,135,442. Shrink packaging apparatus; endless conveyers. WELDOTRON CORP. 29 Dec., 1965 [15 Feb., 1965], No. 55111/65. Headings B8A and B8C. [Also in Division F4] In an apparatus for heat-shrinking a film wrapper around a package, after the film has been partially shrunk, further heat and pressure are applied to one or more surfaces of the package to further shrink and smooth the wrapper round the package. In one embodiment, a package 124, Fig. 1, is carried by conveyer 14 through a heating tunnel 12 and under a freely rotatable, spring loaded, vertically adjustable roller 100 which smooths out wrinkles in the shrunk foil. This roller has an outer sleeve of heat resistant material e.g. a composition of silicon sponge rubber. The roller may be heated by the hot air in the tunnel or may be self-heated. The tunnel 15, Figs. 1, 2, comprises an outer casing 12 which surrounds and is spaced from apertured walls 72, 74, 76 and 78 of the heating chamber. Hot air is blown into the space between the casing and the wall through a tube 86. The conveyer 14 consists of horizontally spaced chains 16, 18, connected by freely rotatable rollers 20 each of which has an outer covering (28), Fig. 4, (not shown), of heat resistant material, e.g. a composition of fibre glass and silicon rubber. On the upper run of the conveyer, the rollers are supported by similarly covered steel bars 30, the covering providing frictional engagement between the rollers 20 and bars 30 so that the former are rotated. Thus the lower surfaces of packages on the conveyer are exposed over their entire area to hot air. In a second embodiment, Figs. 5, 6 (not shown), the bottom surface of the package is also smoothed in an exactly similar manner by a second driven roller (130), identical to the roller 100. In this case, the conveyer, is divided into two independent portions (14A), (14B) arranged on either side of the roller 130. An additional apparatus, Figs. 7-10 (not shown), by which the side edges of the package are smoothed, may be connected to the left-hand end of the apparatus of Fig. 5 (not shown). In this apparatus, the package is carried by a conveyer (14D) between side guides (220A), (224A) and between two heated smoothing, spring biased, horizontally adjustable rollers (230). The package is then turned through 90 degrees as one of its corners abuts a rotatable arm (235), Fig. 9 (not shown), and is finally advanced between guide rails (220B), (224B) and passes between rollers (242), exactly similar to the rollers (230), which smooth the other side edges of the package.

Abstract: 1,195,080. Solvent recovery from finelydivided organic material. BLAW-KNOX CO. 28 Dec., 1967, No. 58867/67. Heading B1B. Solvent, e.g. hexane, is stripped from finelydivided organic material, such as protein meal obtained as by-product in the solvent-extraction of oil from rice bran or corn germ, by introducing the meal through tube 8 into a high-velocity stream of superheated solvent vapour which carries the meal through conduit 9 where most of the solvent vaporizes from the meal. The solvent vapour is separated from the meal in cyclone separator 10, and the meal is then contacted in reservoir 12 with a countercurrent of inert gas, such as carbon dioxide or nitrogen, in order to remove the last traces of solvent. The meal is finally carried by a stream of cool air along conduit 20 into cyclone separator 21 from which the product is discharged through valve 22. Some of the solvent vapour leaving cyclone 10 through opening 10d is drawn through conduit 25 by compressor 26 into tubular heater 27 wherein the solvent is heated to a temperature in the range 120‹-150‹F., higher than the atmospheric boiling point of the solvent. This superheated solvent vapour is then passed to conduit 9 through conduit 28 and constriction or venturi 29. Excess solvent vapour is bled off from conduit 25 through pipe 30 and passed to condenser 31 which comprises water-cooled tubes 31b and waterspray 32a. A mixture of water and solvent condensate is discharged through pipe 31h.

The bolster 35 is pivoted at 33 to a bogie H- frame 23 whose ends are resiliently supported in apertures in two separate bogie side frames 9, 11, 13, 15 by means of vertical (or inclined) laminated metal-rubber V-shaped springs 25, but the vertical loads on the bolster 35 are transmitted to the bogie by side bearing surfaces 37 on the bolster which engage bearing surfaces 39 either on the side frame parts 11 or on the H- frame 23, so that the H-frame 23 may be of light weight. The springs 25 yield vertically in shear to permit tilting of the side frames 9, 11, 13, 15 in vertical longitudinal planes but resist in compression any movement transversely and longitudinally of the side frames 9 &c. relative to the H-frame 23. The bearing surfaces 39 are supported via elastomeric pads 42 on the side frame parts 11 to allow differential tilting of the side frames without disturbing the side bearings. Pneumatic springs 38 are flexible transversely, and links 41 connect the underframe U with the bolster 35 to prevent swivelling therebetween and to transmit longitudinal forces. In another embodiment, in which the bearing surfaces 39 are on the H-frame 23 and the V-shaped springs 25 are inclined longitudinally upwards and outwards, the elastomeric pads 41 are omitted and the V-shaped springs 25 support part of the weight of the vehicle body. The V-shaped springs 25 are supported on blocks seated on the side frame parts 11 and shims may be inserted between block and part 11 to compensate for wheel wear by inserting a flanged rod into a bore in the part 11 in which a projection on the block is disposed and using a jack between the flange and the trackbed to elevate the block.
