Patent GB-583367-A (GB)
Title: Improvements in and relating to synthetic resinous condensation products
IPC: C08G12/30
Filed: 1944-02-07
Abstract: Synthetic resinous condensation products are prepared by heating together under alkaline conditions an aldehyde and p-sulphamylanilino, amino, 1, 2, 4-triazole.  The term aldehyde is defined as including polymeric aldehydes, hydroxy aldehydes and aldehyde-addition products which yield aldehyde under the conditions of the reaction.  Alkaline conditions may be produced by addition of sodium, potassium or calcium hydroxide, sodium or potassium carbonate or mono-, di- or tri-amines.  The reaction may be carried out in presence of solvents, diluents, fillers, other natural or synthetic resinous bodies or of other reactive bodies as illustrated in the examples.  The reactants may be mixed together simultaneously or in various orders, e.g. as described in Specification 542,932. Thermoplastic products may be used as plasticisers for other resins, and thermosetting ones, alone or with addition of fillers, pigments, lubricants, plasticisers, curing agents for moulding compositions. Liquid products may be concentrated or diluted for use as coating compositions, adhesives, coating resins, or may be dried and granulated to form clear moulding powders.  Films may be formed by coating some of the liquid products.  In the examples: (1) para-sulphamylanilino, amino, 1-2-4-triazole is condensed with alkaline formaldehyde by heating under reflux.  Addition of chloroacetamide, glycine, sulphamic acid or other curing agent with or without dehydration yields a thermosetting resin.  By heating the syrupy product with chloroacetamide and mixing with a -cellulose flock and zinc stearate a moulding powder is obtained.  Example 2 is similar but includes urea in the reactants.  (3) Para-sulphamylanilino, amino, 1-2-4-triazole was added to an alkaline syrupy phenol-formaldehyde condensation product, the mixture heated under reflux and acidified with oxalic acid.  A moulding powder was prepared by addition of a -cellulose, and zinc stearate followed by drying and grinding.  (4) Similar to Example 1 with furfural in place of formaldehyde.  (5) Employs acrolein as the aldehyde.  (6) Similar to (1) with butyl alcohol as a modifying agent.  (7) Similar to (1) with diethyl malonate as a modifying agent.  (8) Acetamide is used as a modifying agent.  (9) Glycerine is used as a modifying agent.  (10) Polyvinyl alcohol is used as a modifying agent.  United States Specification 2,332,302 is referred to.  Reference has been directed by the Comptroller to U.S.A. Specification 2,332,302.

Abstract: 781,683. Angular bending. BLACKHAWK MFG. CO. Jan. 27, 1956 [Feb. 23, 1955], No. 2683/56. Class 83 (4). A pipe bender has a plunger for moving a pipe-bending shoe between a pair of pipe engaging reaction blocks pivotally mounted in selected holes of several series formed in a normally fixed plate and extending in opposite directions away from the path of advancement of the shoe, one of the reaction blocks being movable to actuate a device adapted to indicate the extent to which the pipe has been bent by the plunger shoe. A bending shoe 19 or 21 is detachably secured to a ram 8 guided in a ram cylinder 9 and actuated by a lever-operated hydraulic pump. A plate 10 fixed to the cylinder 9 has two series of holes 11, 12 diverging away from the cylinder end and two further diverging series of holes 41, 42. Another plate 13 similarly formed with holes 14, 15 and 43, 44 is detachably secured to the cylinder 9 parallel to the plate 10. Two reaction blocks 22 are mounted to pivot about pins 50 in selected holes of the plates 10, 13. Each block 22 has four side grooves 49 of different widths to accommodate different sizes of pipe 59 to be bent. An angle indicator plate 23 is attached to one of the blocks 22, two pins 52 (not shown) on the plate 23 engaging a suitable two of four sockets 51 in the block 22, so that the indicator plate 23 turns with the block 22 as the latter is moved about its pivot on the bending of the pipe by the shoe 19 or 21 between the blocks 22. If the indicator 23 extends outside the plate 13 lines 53 on the indicator co-operate with a line 39 through the holes 14 to indicate the extent of the bend. If the indicator 23 is positioned to lie between the plates 10, 13 marked circles 54 on the indicator show through the holes 14 to indicate the extent of the bend. A scale 34 on the ram 8.indicates the extent of its forward movement. The apparatus can be used for straightening pipes in which case the blocks 22 are pivoted in the holes 41, 42 and 43,44.
