Patent GB-685729-A (GB)
Title: Production of polyurethanes
IPC: C08L75/00
Filed: 1950-10-04
Abstract: Polyurethanes are prepared by feeding to a reaction zone in the form of streams, an aqueous solution of a polyamine, an acid-binding substance and a bis-chloroformate which is preferably in solution in an inert water-immiscible organic solvent, e.g. toluene, the streams being so constituted that there is no substantial reaction until the re-agents are mixed in the reaction zone.  Usually two streams, one containing the polyamine and acid binder and the other the bis-chloroformate, are used.  A suspension of polymer is continuously removed at a rate equal to the rate of feed of the re-agents.  The acid binder may be an excess of the diamine but is preferably an alkaline neutralizing agent, e.g. sodium carbonate, sodium hydroxide and di- and tri-sodium phosphates.  An emulsifying agent, preferably sodium lauryl sulphate may be used and a dispersed pigment may also be fed to the reaction zone to give a coloured product.  Equimolar quantities of a polyamine and bis-chloroformate are preferably used to give long chain linear compounds.  Branched polymers may be obtained with polyamines of higher functionality than two, particularly if an excess of bis-chloroformate is used.  The volume of the reaction zone and rate of feed of reagents are preferably such that the residence time is 0.3-3 minutes.  The concentration of the reagent solutions is preferably from 0.4 to 1.0 moles of polyamine and bis-chloroformate per litre of solution and a molar excess of alkaline neutralizer of about 10-75 per cent is used.  The temperature may be 0-35 DEG  C.  The Specification lists large numbers of polyamines and emulsifying agents that may be used and of diols from which suitable bis-chloroformates may be prepared by reaction with phosgene.  In examples polymers having intrinsic viscosities ranging from 0.93 to 1.70 were prepared from: examples (1) to (6) tetramethylene diamine and 1,4-butane-diol bis-chloroformate under various conditions; (7) ethylene diamine and 1,4-butane-diol bis-chloroformate; (8) and (9) ethylene diamine, tetramethylene diamine, and 1,4-butane-diol bis-chloroformate; (10) as in (4) with titanium dioxide as a pigment; (11) as in (10) using Franconia Blue instead of titanium dioxide.  Some of the polymers were melt-spun into filaments. Specification 683,504 is referred to.

Abstract: 808,469. Making heat exchanger walls: weldinb by fusion. BABCOCK & WILCOX Ltd. Aug. 1, 1957 [Aug. 1, 1956], No. 24395/57. Classes 83 (2) and 83 (4). [Also in Group XII] A method of forming a tube wall or panel for a steam boiler or furnace in which said wall or panel has two lengths of tube joined together along their lengths, comprises bringing the two lengths of tube into position relatively to each other, welding the lengths of tube together by spaced strength welds and then connecting the lengths of tube together between the strength welds by means of seal welding or soldering so that gas cannot pass between the lengths. In an embodiment, tubes 10 forming part of a tube wall or panel are welded together by spaced welds 11 and then seal welded or soldered as at 12 (Fig. 3). If the diameter of the lengths of tube is small, narrow inserts of circular or rectangular cross-section may be placed between the tubes to facilitate the welding. In another embodiment a spacing member 15 is positioned between adjacent tubes (Fig. 6) and welded thereto by spaced welds 16, 16<SP>1</SP> at the front and rear of the spacing member. Finally the seal welds 17, 17<SP>1</SP> are added. The spaced strength welds are effected by arc or oxy-fuel welding and the seal welding by using a weld metal which will produce a gas-tight weld at a lower temperature than that reached in the strength welding. Thus the temperature to which the greater part of each length of tube is raised can be kept comparatively low with a correspondingly reduced tendency to warp.

Title: Cradle lock mechanism for coin testing devices
Inventor: SORACI ORESTE
Filed: 1971-04-19
Abstract: 1280618 Coin testers VENDO CO 19 April 1971 [18 Aug 1970] 24618/71 Heading G4V A cradle lock mechanism for use in a coin testing mechanism tests coins for weight and diameter. A coin enters the mechanism from above and, if it is of the correct diameter, rests on the leg 52 and pivotable assembly 16 of the cradle 14 which are spaced apart at slightly less than the diameter of the coin under test. This coin then unlocks the cradle 14 by displacing the assembly 16 in an anti-clockwise direction about its pivot 54 so that latch 60 is moved out of contact with ledge 66. If this coin is of the correct weight the cradle then pivots in an anticlockwise direction so that the accepted coin passes into the shoot 34. When a coin of incorrect diameter and/or weight arrives at the cradle 14 one of the following situations may occur. A coin of too great a diameter will not unlock the assembly 16 and the same will occur for coins of a diameter slightly less than acceptable. These coins will remain on the cradle and a scavenging operation will then have to occur, preferably including the swinging up of the wall 20 to expose the cradle. Coins of too small a diameter will pass between leg 52 and assembly 16 and if a subsequent testing mechanism for coins of a smaller diameter is present then lug 68 may be fitted to the cradle to deflect such coins into a shoot leading to it.
