Die PSS Wellendichtung Typ B ist eine mechanische Gleitringdichtung. Die Dichtfläche entsteht zwischen den ebenen Flächen des rotierenden Edelstahlrotors und dem stationären Kohleflansch.Der stationäre Kohleflansch wird mit Schlauchklemmen an der Vorderseite des Balges und das hintere Ende des Balges über das Sternrohr befestigt und wird mit Schlauchklemmen gesichert. Der Edelstahlrotor ist auf der Welle vor dem Kohleflansch montiert. Der Edelstahlrotor wird verwendet, um den Balg zu komprimieren, bevor der Rotor mit Stellschrauben an der Welle befestigt wird. Diese Kompression (Vorspannung) sorgt für einen konstanten Kontakt zwischen den beiden flachen Seiten des Edelstahlrotors und des Kohleflansches. Dadurch kann die PSS Wellenabdichtung die variable Vorwärts- und Rückwärtsbewegung - bedingt durch den Propellerschub - ausgleichen. Der Kohlenstoffflansch ist zum Wellendurchmesser überbohrt, so dass er um die Welle herum 'schwimmen' kann und somit die meisten Fehlausrichtungs- und Schwingungsprobleme ausgleicht. Der Rotor aus rostfreiem Stahl ist durch zwei O-Ringe, die in die Bohrung des Kragens eingelassen sind, gegen die Welle abgedichtet. Diese O-Ringe rotieren mit der Welle und dem Edelstahlrotor und unterliegen keinem Verschleiß während des Betriebs.

History of Egypt
Format: Kindle
Egypt has played a vital role throughout history. This book traces and evaluates the history of Egypt from ancient times until the modern period. During ancient times, the Pharaohs created a strong Egypt. During the Ottoman times, Egypt played a significant role as a regional power. Both French and British played a vital role in Egyptian politics. The Suez canal put Egypt, an important player in world commerce. The Nasser regime entered Egypt into cold world politics. The USA managed under Sadat to place Egypt at the American camp. Eventually, Egypt was the first Arab country to sign a peace treaty with Israel after various brutal wars. Egyptian culture dominated western civilization throughout the centuries. The reader will enjoy this book.

Great summary of Egyptian history
Format: Kindle
The book is—as the subtitle states—an “Overview of Egyptian History.” The book is a brief summary of Egypt’s long and interesting history. It starts with historical events: who were the rulers? What territories did Egypt conquer? Who conquered Egypt. The second part of the book discusses social, economic, and religious history.
This primer lays out all of the above topics but with little detail so the reader may wish to select topics of interest to study in further depth elsewhere. Because Egypt’s history includes millennia, I find it hard to understand, so reading this book was valuable to me.
The book is written in a style that makes it easy to read. It is not at all dry as some textbooks can be.
I recommend this book to anyone who wants an overview of Egyptian history and look forward to reading other books in the series.

Far from enthralling, but I did learn
Format: Paperback
This book was a disappointment. It looked like exactly what I was looking for: an overview of the history, society, and culture of Egypt from ancient to modern times that wasn't 500+ pages long. I did learn a fair bit of information, but unfortunately, the book is far from "enthralling." It reads like a high school student's book report. In addition, it sometimes just throws terms out there with no explanation, and I found myself having to consult Google. For example, it says "Since hieroglyphs were difficult to create, the Egyptians developed hieretic writing, which was a type of cursive script. Later, demotic writing was developed for ordinary documents." What is demotic writing? How is it different from hieretic? The book doesn't even provide a picture. I had to go to Wikipedia to find out what these things are. This book needs slightly more detail and an author with better writing style / storytelling abilities. That said, it still may be the best short introduction available.
