Patent NL-299732-A (NL)
IPC: C07F9/10
Abstract: The invention comprises a phosphorus-containing polyether obtainable by reacting an epihalohydrin and a polyol component which comprises a sugar alcohol containing 5 or 6 carbons, a triol and orthophosphoric acid as described below.  The reaction is suitably effected in the presence of an acidic fluorine-containing compound as catalyst, e.g. fluoboric acid.  The term orthophosphoric acid includes strong phosphoric acid which contains in addition to orthophosphoric acid, pyrophosphoric acid and possibly higher polyphosphoric acids.  In an example a mixture of glycerine, sorbitol and phosphoric acid is heated to 85 DEG  C., fluoboric acid is added as catalyst and the temperature maintained between 86 DEG  C. and 92 DEG  C. during the addition of epichlorhydrin, and the mixture allowed to stand for 2 hours after the addition.  The reaction mass is neutralized with triethanolamine.  The epihalohydrin is preferably epichlorhydrin and the ratio of the number of moles of epihalohydric to the number of hydroxyl groups in the polyol component is preferably 0.5: 1 to 6: 1. The polyol component is preferably a mixture of from 80 to 30 equivalent weight per cent of the sugar alcohol, preferably sorbitol, and 20 to 70 equivalent weight per cent of the triol, preferably glycerine, and orthophosphoric acid taken together, and the amount of orthophosphoric acid is preferably such that the polyether contains 0.3 to 2.5% by wt. of combined phosphorus.

Title: Shroud ring for turbine stator blades - formed from arcuate apertured segments bowed to fit onto blade tangs
IPC: F01D5/22
Filed: 1978-03-02
Abstract: A one-piece arcuate inner shroud ring is formed with aperture spaced circumferentially comparable to the spacing of the inner ends of the blades in the series. The diameter of the apertures exceeds the diameter of the blade journals. Force is applied to the encs of the ring to control or bow the same sufficiently to permit insertion of the contracted ring into the series of blades.

Abstract: A fluid foodstuff to be pumped through a pipeline over a long distance, is divided into bathces. Each batch is shorter than the length of the pipeline, and is pushed through, in front of a plug makes a seal on the pipe wall. In each batch there is >=1 m3 of fluid and the internal dia. of the pipe is >4 cm. The length of the batch is >10000 times and 100000 times the internal dia. of the pipe. The pressure exerted to move the batch is =800 kPa and is derived from compressed gas. A plug is also inserted in front of the batch and a quantity of rinsing water is pumped through in front of and behind the batch. The pipes are of a material such as polyethylene and the plugs are flexible balls of a similar elastomeric material to the pipe walls. They may be hollow, of polypropylene oxide, be filled with gas under pressure and have a dia. of 0.7-2% greater than the internal dia. of the pipe. The pipeline is relatively cheap and all the variables can be held within tolerable limits so that damage such as butterising in the case of milk is avoided and the quality of the foodstuff is not affected.
