    摘要: The invention provides a novel method for the preparation of a lower alkyl, e.g. methyl, ester of fatty acid by the alcoholysis reaction of fatty acid glyceride, i.e. naturally occurring oils or fats, with a lower alcohol, according to which high-quality products containing very small amounts of colored or coloring impurities are readily obtained without the necessity of troublesome procedure or expensive apparatus as in the conventional methods. The inventive method is in principle a two-step alcoholysis reaction and the product obtained in the first step is separated from the by-product glycerine and then subjected to the second alcoholysis reaction followed by admixing of an appropriate amount of water and phase separation so that the undesirable impurities transfer into the aqueous layer and readily separated from the ester product.

    摘要: A number of embodiments of rotating electrical machines and methods for winding them that provides a high space utilization and very effective winding with less likelihood of damage to the insulation of the wire of the winding during the winding process. The arrangement basically does not require the winding needle to be moved back and forth in the slot between the poles but rather employs insulating inserts that are positioned on the axial faces of the poles outside of the gaps for guiding the wire from one end to the other so as to provide the high space utilization. In one embodiment the insulating insert effectively changes the circumferential length of the coil winding that decreases in an axial direction along their length.

    摘要: Two embodiments of winding methods and apparatus for winding coils of a rotating electrical machine where the armature teeth are skewed. The winding mechanism and method operates so that the winding needle does not have to enter to the bottom of the slots between the pole teeth but the wire is wound around the pole teeth from one end thereof with an arrangement for causing the windings to progressively move down the pole teeth as the winding continues.
