Abstract: 1,140,911. Extrusion-blow moulding; filling. STEELE and COWLISHAW Ltd. 26 April, 1966 [18 May, 1965; 16 Aug., 1965; 31 Aug., 1965], Nos. 21026/65, 35013/65 and 37140/65. Heading B5A. [Also in Division B8] An extrusion/blow-moulding and filling machine comprises an extrusion head, and a main mould carrier, movable relatively to each other from a position where the carrier is below the extrusion head to receive tubular extrudate in the main mould, to a position beneath a mandrel having passages connected to a supply of blowing air and to a supply of the contents, which may be liquid or granular, the mandrel being vertically reciprocable into and out of the tubing for expansion thereof and for filling the moulded article. As shown in Fig. 1, a tubular parison 36 is extruded from extrusion head 29, and mould halves (56, not shown), mounted on platens 49 of carrier 26 are closed about the parison by means of hydraulic ram 55. The extrudate is severed by a reciprocating blade 42 operated by hydraulic ram (44, not shown) while a puff of air is supplied to the interior thereof through channel (45, Fig. 2, not shown) of extrusion head 29 (also Fig. 10(b), not shown), so as to form a bell-mouthed opening at the top thereof to prevent inward sagging and for easy, subsequent entry of the blowing mandrel. Carrier 26 is then reciprocated laterally by hydraulic ram 51 to beneath blowing mandrel 50, while another mould carrier 26 is moved from beneath its own mandrel 50 to beneath the extrusion head 29. Blowing mandrel 50 is lowered by ram (67, not shown), the article is expanded thereby (Fig. 10e, not shown), and filled thereby (Fig. 10f, not shown). A subsidiary neck-mould (89) may then be closed to form the neck-portion (Figs. 10g-i, not shown) which may be threaded, by compression moulding, vacuum forming or blow-moulding with or without a spigot (117, Figs. 18, not shown) as a core. A preferred form of mandrel is shown in Fig. 9 and comprises three concentric cylinders 58, 59, 60 which form an inner, first passage 70 connected to a supply of blowing air 72, a second passage 76 connected to a supply of the contents 78 to fill the moulded article, and a third, outer passage 81 to exhaust the air from the moulded article while filling. The second passage 76 may be sealed off by lowering the central cylinder 58 on to a conical seating 80 by means of ram (68, not shown), and the inner passage 70 may be closed by a spring-loaded poppetvalve 75 which may be opened by the air pressure.

Patent GB-724097-A (GB)
Title: Improvements in or relating to the preparation of nitrogenous resinous condensates
IPC: C08G12/46
Filed: 1951-09-06
Abstract: Water-soluble resinous condensates useful for improving the wet-strength of paper are prepared by reacting formaldehyde with the reaction product (which may contain free urea) of urea and the reaction product of a polyethylenepolyamine of molecular weight not less than 146 (triethylenetetramine) and a dihaloalkane having not more than three carbon atoms.  The polyethylenepolyamine to be reacted with the dihaloalkane may be prepared from a lower ethylene polyamine by a preliminary reaction with a dihaloethane.  The polyethylene polyamine and dihaloalkane are reacted preferably in a solvent such as water or alcohol, at p  70-150 DEG  C., if necessary under pressure, in a ratio of dihaloalkane to amine of from 0.7 to 1 to 1.6 to 1.  The reaction is stopped when an aqueous solution containing 60-65 per cent of the products has a Gardner-Holdt viscosity of N to Z3, preferably U to Z1.  The reaction may be carried out in stages, adding dihaloalkane and preferably neutralizing the hydrohalide formed, at each stage.  The product is then reacted with urea in the presence or absence of water and in a ratio of urea to -NH- groups (including terminal NH2 groups) in the product of 0.2 to 1 to 1.5 to 1.  The reaction is continued at 100 DEG  to 200 DEG  C. until a 50 per cent aqueous solution of the solids has a Gardner-Holdt viscosity of B to M, preferably C to H. The extent of reaction is estimated by measuring the ammonia evolved. Finally, the product, dissolved in water to give a 20-70 per cent solution, is reacted at 20-100 DEG  C. with formaldehyde in a molar ratio of formaldehyde of 0.6 to 1.5 per hydrogen atom on nitrogen, each -NH-group in the polyethylene polyamine-dihaloalkane product unreacted with urea being regarded as providing one hydrogen atom for reaction with formaldehyde, each reacted urea molecule two hydrogen atoms and each unreacted urea molecule four hydrogen atoms.  With formaldehyde ratios below 0.5 the products tend to gel.  Excess formaldehyde, however, has no harmful effects.  The formaldehyde may be provided by a revertible polymer.  The final product is an aqueous solution which may be used as such or spray-dried.  It may be mixed with a water-soluble urea- or melamine-formaldehyde condensate.  In a typical example 94.5 parts tetra-ethylenepentamine of 88 per cent purity were reacted with 49.5 parts ethylene dichloride in water under reflux for four hours.  After neutralization and removal of water 50 parts of the product were reacted with 72 parts urea, 10 parts ammonia being evolved.  The product was dissolved in 200 parts water, and 62.4 parts of this solution reacted with 62.4 parts 36 per cent formaldehyde at 95 DEG  C. for 30 minutes yielding 127.5 parts of a resin solution containing 25.3 per cent resinous solids and suitable for improving the web strength of paper.  The viscosities of solutions of the initial condensation product and of product obtained therefrom by reaction with urea were W and E at the specified concentrations.
