Title: A machine for wrapping and packaging articles
IPC: B65B11/54
Filed: 1948-09-09
Abstract: 657,125. Wrapping-machines. MORGENSTERN, K. D., and IDEAL PACKAGINGS. Ltd. Sept. 9, 1948, No. 23732. [Class 94(i)] [Also in Group VIII] A machine for wrapping articles such as oranges in a sheet of thermoplastic material comprises a supporting plate 1 formed with an aperture 2, a pivoted clamping plate 6 formed with an aperture 7 slightly larger than the aperture 2, and a pivotallymounted, electricallyheated element 8 which is so dimensioned as to enter the aperture 7 and rest on the edge of the aperture 2. In use, a web of wrapping material is fed from a supply reel over the plate 1 and clamped in position covering the aperture 2 by means of the plate 6. The heating element is then swung down until it rests against the wrapping material over the aperture and is returned to the inoperative position when sufficient heat has been imparted to the material to render it plastic. The article is then passed downwardly through the two apertures thereby stretching the heated wrapper and causing it to conform closely to the shape of the article, and the package completed by twisting the article and wrapper relatively to the support to form a sealed neck 10. The package is finally severed from the web by a transversely-movable knife 40, (see Group VIII). The plate 6 is carried by arms 16 pivoted to a bracket 17 and is fitted with locking means comprising two arms 19 pivoted at 20 and formed with lugs 32 adapted to engage under pins 33 on the supporting plate. These arms are normally locked to the plate by the engagement of pins 31 on members 23 with notches 30 in bent portions '29 of a member 28 secured to the plate, the members 23 being slidable relative to the arms to an extent determined by the engagement of pins 26 with the ends of slots 25 in the arms and being biassed inwardly by springs 27 acting between a transverse member 24, interconnecting the members 23, and a handle 21, 22. In order to swing the arms to the clamping position the member 24 is pulled outwardly by grasping the handle 21 to disengage the pins 31 from the notches 30. On the return movement to unlock the plate, the pins 31 ride up inclined parts of the members 29 and engage in the notches 30 automatically so that the plate 6 may be swung to the inoperative position by a continuous movement of the handle. The heating element is carried by arms 35 provided with a handle 38 and pivoted to the bracket 17, a switch and rheostat 50 being provided to control the heating current.

Title: Process for the manufacture of reaction products of polyisocyanates with alkylene oxide addition products
IPC: C10G33/04
Filed: 1956-08-10
Abstract: Polyisocyanates are reacted with addition products having a molecular weight of at least 1000 of an alkylene oxide with a compound containing at least 8 carbon atoms and only one hydrogen atom capable of reacting with the alkylene oxide.  Suitable polyisocyanates are hexamethylene, toluene, naphtylene-1,5-, 4,41-diphenyl - methane, 4,41 - diphenyl, and 1,4-phenylene di-isocyanates, and triphenyl-methane triisocyanate.  Suitable alkylene oxides are ethylene and 1,2-propylene oxide and substances to which the alkylene oxide may be added are dodecyl, cetyl, octadecyl, octadecenyl and hydro-abietyl alcohols; myristic, palmitic, stearic and oleic acids; octyl-, nonyl- and dodecyl-phenol; didodecylamine, dioctadecylmercaptan.  In the case of monocarboxylic acids the alkylene oxide may be first polymerized and then esterified to form the ether ester.  Raised reaction temperatures may be employed, solid reactants being melted or dissolved.  Residual alkaline catalyst in the alkylene oxide adduct is neutralized with an acid, acid chloride or anhydride to moderate the subsequent reaction which may be strongly exothermic.  In the examples: (1) the adduct of 25 mols. ethylene oxide with 1 mol. octadecyl alcohol is fused, neutralized with acetic acid and reacted at 70 DEG  C. with 1 equivalent of toluylene-2,4-diisocyanate; the product forms viscous aqueous solutions, one of 50% strength being a stiff gel; (2) the adduct of 120 mols. ethylene oxide with 1 mol. of commercial oleyl alcohol is reacted with diphenylmethane-4,41-diisocyanate; (3) the adduct of 100 mols. ethylene oxide with 1 mol. commercial hydroabietyl alcohol is reacted with varying proportions of diphenylmethane - 4,41 - diisocyanate; (4) the adduct of 50 mols. ethylene oxide with 1 mol. p-n-nonylphenol is reacted with naphthylene-1,5-diisocyanate; (5) the adduct of 150 mols. of ethylene oxide with 1 mol. of m -heptadecyl benzimidazole is reacted with toluylene-2,4-diisocyanate; (6) the adduct of 150 mols. of ethylene oxide with 1 mol. stearic acid is reacted with 6 equivalents of toluylene-2,4-diisocyanate to produce a water-soluble wax-like mass, with 8 equivalents to produce a filament-forming material and with 10 equivalents to produce a tough rubber-like mass no longer soluble in water; (7) an adduct from 40 mol. of ethylene oxide, 10 mols. of 1,2-propylene oxide and 1 mol. of commercial oleyl alcohol is reacted with hexamethylene-1,6-diisocyanate; (8) the adduct from 150 mols. of ethylene oxide with 1 mol. lauryl mercaptan is reacted with toluylene - 2,4 - diisocyanate.  The products generally are water-soluble yielding viscous solutions useful for the production or stabilization of emulsions or suspensions, and especially for thickening oil-in-water emulsions used for pigment printing.
