Patent GB-1123395-A (GB)
Title: Production of cross-linked polyurethanes
Inventor: DIETRICH DIETER
IPC: C08G18/10
Filed: 1966-06-02
Abstract: Cross-linked polyurethanes are prepared by reacting a polyhydroxyl compound having reactive hydrogen atoms and a molecular weight of 300 to 20,000, a polyisocyanate and a compound having at least one reactive hydrogen atom and at least one N-alkoxymethyl group, and if desired a chain extending agent, and allowing the cross-linking to occur by drying and/or curing the polyurethane.  Conventional polyisocyanates and polyhydroxyl compounds may be used.  The compounds containing at least one reactive hydrogen atom and at least one N-alkoxymethyl group which may be used are N-alkoxymethyl-ureas, urethanes, amides, thioureas, guanidines, melamines and tetrahydropyrimidinones especially adducts of alkoxymethyl isocyanates with diethanolamine, diisopropanolamine, diethylenetriamine, pentaerythritol, alkylene bis - (N - alkoxymethyl-hydroxyethylurethane) and the adducts of alkoxymethyl - (meth)acrylamide and (meth)acrylic acid hydroxypropyl ester methoxymethylurethane with diethanolamine. Chain extending agents which are diols, triols, diamines, aminoalcohols, hydrazines or water may also be added to the reaction mixture.  The N-alkoxymethyl compounds may be reacted with polyisocyanate together with the polyhydroxyl compound but it is preferred to first form a prepolymer from the polyhydroxyl compound and the polyisocyanate and then to react this with the N-alkoxymethyl compound. In order that cross-linking does not take place during the preparation of the polyurethane the reaction is carried out (a) at low temperatures e.g. below 100 DEG  C.; or (b) in the presence of an inert solvent; or (c) in neutral or slightly basic conditions.  The polyurethanes which are modified with the N-alkoxymethyl compound preferably also contain anionic or cationic groups.  Such groups may be introduced by including in the reaction mixture e.g. (1) a glycol or diamine and carrying out the salt-formation with alkylating agents or acids; (2) a reactive halogen diol followed by reaction with a tert.-amine or a sulphide; (3) taurine salts, carboxylic acids and anhydrides thereof, hydroxy- and amino-carboxylic acids, sulphonic acids, lactones, sultones or cyclic sulphates with aliphatic or aromatic diamines or aminodiols or alternatively the polyurethane containing N-alkoxymethyl groups may subsequently be reacted with compounds imparting a salt-type character e.g. with b -chloroethyl isocyanate and pyridine.
Patent GB-879549-A (GB)
Title: Purification of maleic anhydride
Inventor: CUMMINGS HOWARD DAVID
IPC: C07C51/573
Filed: 1958-07-31
Abstract: Crude maleic anhydride containing chromogenic bodies is refined by heating in the presence of added fumaric acid at a temperature of at least 130 degrees in the liquid phase and thereafter distilling purified maleic anhydride from the reaction product.  The material employed may be a stripped or distilled crude maleic anhydride, the stripping or distillation having been carried out under reduced pressure.  It is preferred to heat the crude maleic anhydride at a temperature from 190 degrees to the boiling point of fumaric acid, and the mixture may be heated at or above the boiling point of the crude maleic anhydride.  After heat treatment the molten mass is subjected to distillation, preferably at a pressure not exceeding 100 mm. of mercury absolute, a highly refined product being obtained by distillation at 10-100 mm. Hg. The amount of fumaric added for optimum results is about 1% by weight based on the crude anhydride, but it may be desirable to use 2 to 5% of fumaric acid with very dark crude maleic anhydride.

Title: Improvements relating to flushing valves
IPC: B62M7/00
Filed: 1933-09-06
Abstract: 413,890. Flushing-valves. TANNER, W. C., 21, Palmer Street, Wellington, New Zealand. Sept. 6, 1933, No. 24729. Convention date, Nov. 10, 1932. [Class 135.] Relates to flushing-valves of the kind which necessitate an adjustable time-lag between successive actuations. The main valve 3 supports the usual release valve 2, rockable, to initiate the flush, by engagement of a push-rod 4 with a collar 36 on a rod 21 supported by a head 40 in a sleeve 20 secured to the valve 2. The main body of water, when released, flows around a float-chamber 7 to the outlet 9. Some water, however, enters the chamber through a gauge-covered opening 17 and raises the float 10 to lift a rod 18, which raises the rod 21 and moves the collar 36 from the path of the push-rod 4, enabling the valve 2 to return to its seat and terminate the flush. Rise of a pin 11 secured in the float 10 at the same time releases a cam-headed lever 22 supporting a conical plug 29, which enters a hole 30 as far as is permitted by an adjustable screw 31. The collar 36 falls into the path of the push-rod 4 only when the water has escaped from the float-chamber 7 through the hole 30, the final rise of the plug 29 being rapid. A groove 38 in the loose cover 15 of the chamber 7 provides an air escape.
