Title: Improvements in or relating to hopbacks and mash tuns
Inventor: BARRON THOMAS HENRY
IPC: C12C7/17
Filed: 1963-04-24
Abstract: A hopback or mash tun has a liquid-permeable false bottom 24, Fig. 1, which may be tilted to discharge solid matter into a helical conveyer 36. The false bottom sections 24a, 24b, rotate on shafts 21, 22, respectively, each driven by a motor through non-reversible gearing; a limit switch serves to stop the motor when the shaft has been rotated through a predetermined angle and a reversing switch provides for reversal of the drive at each actuation of the motor.  The arrangement may be such that only one section of the false bottom is moved to its tilted position at any given time, whereby clogging of the conveyer 36 by the solid matter discharged is avoided.  In a modification the shafts are actuated hydraulically.  The false bottom is constructed of wedge wires or bar elements 29, Fig. 4, arranged transversely of the shafts 21 and 22; the widths of the upper surfaces 31 and apertures may be 2 mm. and 1 mm., respectively. The hopback or mash tun may also incorporate one or more partitions (not shown) perpendicular to the shafts and the conveyer 36, extending down to the level of the false bottom sections to form a number of individual working compartments, a rotating water jet 51 to facilitate cleaning, rotary shredding arms or blades 45 and, at the delivery end of conveyer 36, separate outlets for liquid and solids. <PICT:1031048/C6-C7/1> <PICT:1031048/C6-C7/2>

Title: Improvements in or relating to the production of resinous condensation products
IPC: C08G12/34
Filed: 1945-06-26
Abstract: Resinous condensation products are formed by reacting urea, succinamide and formaldehyde or formaldehyde-liberating substance at least part of the reaction being in presence of a monohydric alcohol. Water present with the ingredients of the reaction mixture or formed during the reaction may be removed by distillation if desired with a water-entraining agent which may be returned from the condenser to the reaction zone.  Suitable alcohols are propanol, butanol, amyl alcohol, allyl alcohol, methallyl alcohol, benzyl alcohol, the monoethyl ether of ethylene glycol or mixtures thereof.  Suitable formaldehyde-liberating substances are paraformaldehyde trioxane, and hexamethylene tetramine.  All the ingredients may be mixed initially or one amide substance may be precondensed with formaldehyde and the other then added, for example the starting materials may be dimethylol urea and dimethylol succinamide.  The alcohol may be added initially or at a later stage.  Preferred proportions are two mols. of formaldehyde for each mol. of amide substance, one mol. of succinamide to 4-15 mols. of urea.  The alcohol is used in excess, functioning as a solvent as well as a reactant.  The reaction may be commenced under alkaline conditions, the mixture being subsequently acidified.  The end of the reaction may be determined by the viscosity of the product or by measurement of the quantity of water evolved.  Other aldehyde reactive materials may be present, e.g. melamine, dicyandiamide or a phenolic material.  The products are suitable for use in coating compositions.  Pigments may be incorporated.  Plasticisers, e.g. castor oil may be added or other film-forming agents, e.g. a glycryl phthalate resin modified with castor oil or dehydrated castor oil.  Drying of the film may proceed at ordinary temperatures but preferably a baking treatment is used. Conventional hardening agents, e.g. butyl acid phosphate, chlorinated rubber or chloracetamide.  The products are also useful as adhesives, e.g. for plywood or for laminating fabrics or for binding abrasive particles to flexible backings. Specification 483,399 is referred to.
