Oligomers having at least one structural unit of formula where n is 0 to 20 and the terminal carbonyloxy group is part of a neutralized or non-neutralized carboxyl group prepared by reacting an α,α- dihydrocarbyl-#-proprolactone with an organic compound having at least one non-phenolic carbon bound OH group at 50-175 C. in the absence of an alkaline catalyst. The oligomer may be neutralized with an amine and it may be prepared using no catalyst. Specified OH containing compounds are mono- or polyalcohols with up to 20 C atoms, alkyds, epoxy resins, hydrolysed epoxides (lists are given). The oligomers may be converted to resins by reaction at 175-260 C. with a resin forming compound (i.e. one having either at least one carboxyl group, at least two potential carboxyl groups, or at least two hydroxyl or potential hydroxyl groups) of which lists are given. The oligomer or the resin may be mixed with a phenol-aldehyde or amino-aldehyde resin. The examples disclose reacting pivalolactone with (1) a polyester from phthalic anhydride, 2,2- bis - (hydroxymethyl) - 1,3 - propanediol, di- 1,2-propylene glycol and glycidyl esters of alkanoic acids, (2) a hydrolysed epoxy resin, (3), (4) and (5) trimethylol propane possibly followed either by additional trimethylol propane and neopentyl glycol or by additional trimethylol propane and additional pivalolactone. The products are diluted with 2-butoxyethanol and mixed with aqueous triethylamine or 2-dimethylaminoethanol to give products useful for making paints or lacquers.

Title: Improvements in or relating to nuclear reactor installations
Inventor: CHALLENDER RONALD SCOTT
IPC: G21C9/027
Filed: 1960-11-02
Abstract: 938,190. Containment vessels for nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 31, 1961 [Nov. 2, 1960], No. 37740/60. Drawings to Specification. Class 39 (4). The containment vessel for a nuclear reactor installation is adapted to be unsealed at an initial high pressure developed when the reactor coolant escapes from its closed circuit and then to be resealed at a lower pressure, which, howover, is still above atmospheric. In any accident to the cooling system, the high pressure coolant will escape in two stages; one at high pressure involving uncontaminated coolant and one at a lower pressure with the coolant radio-actively contaminated. The containment vessel need therefore withstand only a slight pressure, e.g. 5 lb./sq. inch, provided there is fitted in the vessel a non-return valve which will release the high pressure uncontaminated coolant and contain the lower pressure contaminated portion. This valve may be simply held shut by its own weight, or may be spring- loaded with its sealing action reinforced by a liquid seal as illustrated in Fig. 2 (not shown). As an alternative to a valve, the containment can be arranged so as to be a pressure-tight housing standing in an annular trough which when filled with liquid, e.g. water, forms a liquid seal between the housing and the atmosphere, the amount of liquid in the trough governing the maximum possible pressure in the housing. If this is exceeded, the liquid seal is broken by disturbance of the liquid level, but as the pressure falls the liquid level returns and the seal is restored.

Title: Device for moulding and coating pipes and like articles
IPC: B05C19/04
Filed: 1946-12-23
Abstract: <PICT:0619788/III/1> <PICT:0619788/III/2> In apparatus for coating pipes &c., the pipe is mounted for rotation and the coating is supplied by a hopper, having at its outlet a strickle having a curved surface which is parallel either to the external surface of the pipe on to a plane tangential to this surface and which determines the thickness of the coating. In Fig. 2, a concrete pipe having reinforcement 2 wound round it is coated by concrete from a hopper 33 and a shoot 7, the lower part 7b of which is curved to form a strickle parallel to the plane tangential to the pipe.  The concrete passes between the pipe and an apron 24 which is moved at the same speed and direction as the pipe on rollers 15-20.  Staves 30 are forced in front of the concrete and are released at the roller 16. Vibrators 11a, 11b and 12 assist the flow of the concrete and remove air.  When the coating is complete, the pipe is removed by shifting the vibrator 12 aside and releasing the apron 24 by lifting a counterweight 27.  The apron may be heated by steam jets 28.  In a modification, Fig. 4, the pipe 41 is rotated on rollers 45, one of which is driven.  When the pipe has been placed on the rollers the concrete hopper 49 is lowered so as to rest on it by means of a plate 54 pivoted to one side of the hopper outlet, the other side of which is formed into a strickle 56, the surface of which is curved parallel with the pipe.  The hopper is carried on counterweighted slings 59. A vibrator comprises a rod 65 mounted in rubber journals and carrying fins 69 and having a pneumatic vibrator on its end external to the hopper.  The plate 54 is hinged upwardly to allow the concrete covering to be completed.  A modification is shown in which four hoppers are used to coat one pipe.  A smoothing plate having a vibrator may be hinged to the strickle 56.
