以下是引用edward在2009-3-27 8:21:34的发言:(N. V. Internationaic xxxxxxxxxxxxxxxxxxxxxx ,,Novadel") DEVENTER (Holland) 上行是公司名稱?下行是地址。 頗像:麥麥集郵公司(香港旺角)

[em01] 田先生搞怪
不过这样看就好办了,似乎应该是: Deventer, Holland : N. V. Internationale Oxygenium Mij. "Novadel"
公司简介,呵呵:
Internationale Oxygenium Mij Novadel. March 11, 1925, [Convention date]. Bleached products ; treatment by damping or heating ; treating with air and gases, with solid substances, with radiations; mixing and agitating. - To improve the appearance and other qualities of meal, flour or milling products one or more organic acid anyhdrides and one or more aldehydes or a mixture of one or more of said anhydrides with one or more aldehydes, or substances which contain or set free these compounds are added to the flour, these materials reacting with air or oxygen present in or poured into the flour, and so producing a flour-improving substance actually in the flour. Oxygen or gases containing or setting free oxygen or mixtures which can liberate oxygen is or are blown through the flour &c. and added materials. As specific examples of the process (i) benzaldehyde and acetic anhydride or (ii) acetaldehyde and acetic anhydride or (iii) butaldehyde and succinic acid anhydride are successively injected into wheat flour after which air is blown through for some time. Anhydrides and hydrogen peroxide or peracids and anhydrides may be used the blowing through of air not then being necessary. Catalyzers such as salts of chromium, cobalt, iron, uranium and vanadium may be used with materials setting free the flour-improving substances, such catalyzers being used with or in place of weak alkaline reacting materials. Any acid-reacting, material produced in the flour during the process may be neutralized by the addition of an alkaline substance such as bicarbonate of soda. Oxygen may be passed through the flour containing the materials to produce the flour-improving substance, or compounds to produce oxygen may be mixed with the materials. Heat may be applied to the flour containing the materials. The activity of the materials may be increased by mechanical or physical treatment, such as stirring, exposure to ultra-violet light, or the like. The flour or meal may be dropped down a tower and the added substances blown in the opposite direction, or the flour or the like may be carried in a thin layer through a room in which the added substances are atomized.
