PRO Shaft Seal 3" Shaft & 4-1/2" Tube

The PSS PRO Shaft Seal is a mechanical face seal utilizing our proven stainless steel and carbon sealing components but adds reinforced silicone bellows, a secondary shaft retention collar, 316 Stainless Steel hose clamps (rolled edges and non-perforated), and an optional Nitronic 50 rotor upgrade (for highly corrosive environments). Designed specifically for applications that will require increased durability and resistance to harsh, corrosive, high pressure, and otherwise demanding environments. The PSS PRO Shaft Seal is a specialized mechanical seal suitable for various applications, with unmatched performance.

As with PSS Type A & B Seals, The PRO Shaft Seal is a mechanical face seal. The sealing surface is created between the flat surfaces of the rotating stainless-steel rotor and the stationary carbon flange. The stationary carbon flange is attached to a heavy-duty silicone bellows attached to the vessel’s stern tube (shaft log), with 316SS hose clamps. The stainless-steel rotor is fitted on the shaft in front of the carbon flange and is used to compress the bellows, the rotor is then secured to the shaft with set screws, and the shaft retention collar is installed. This compression (pre-load) maintains constant contact between the two mating faces of the stainless-steel rotor and carbon flange, allowing the PSS to compensate for the variable axial movement due to propeller thrust. In addition, the carbon flange is over-bored to the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration from the drive-line. The stainless-steel rotor is sealed to the shaft by two O-rings recessed into the rotor's bore. These O-rings rotate with the shaft and the stainless-steel rotor and therefore do not experience wear during operation.

A Refreshing Approach to Presentations
Format: Paperback
I ran across this book while researching a college workshop on perfecting presentation, dealing with public speaking and effective use of PowerPoint. As one who has suffered through numerous electronic slides that did little or nothing to augment the speaker's efforts, I was delighted to see this fresh and innovative approach. I believe this process works best, however, when one's speech is primarily persuasive in nature. Although these ideas helped me set up a strong introduction and conclusion, in a recent lecture I resorted to bullet points for the material I felt the students had to master. Perhaps as I get more used to Atkinson's technique, I'll better about using it in lecture. However, the business applications seem quite worthwhile. My students' workshop presentations that used his techniques were highly engaging. I highly recommend this book and the supporting web site.

Simplistic and Inappropriate
Format: Paperback
I was hoping this book would provide insights into how to present complex information in a more comprehensible, useful format, using PowerPoint as the tool. Instead, the overall gist of this book is that presentations should be "dumbed down" as much as possible. The theme the author presents is that presentations should be story based. This is reasonable. However, the method the author recommends is that essentially *all* meaningful, complex (or, as the author prefers "boring") content be removed from the presentation. Presentations then become nothing more than catchy headlines and colorful graphics. All content should be in the presenter's notes (not typically to be provided). This is juvenile and useless and frankly reflects a complete lack of understanding of how presentations are made in a complex business environment.

On the right track
Format: Paperback
This book is a good introduction about how to use story-telling techniques in PowerPoint presentations. There are some good ideas here that you won't find in technical manuals. If you don't know film techniques these will be eye-opening. But the book could have been much stronger if it were to push these concepts to the next level. I saw a PowerPoint presentation with Andy Goodman, who teaches more or less the same thing, and his presentation nailed these concepts more cleanly than this book does. But again, this book is definitely worth checking out if you haven't studied storytelling before.

An Essential
Format: Paperback
I've created PowerPoints for executives in major corporations and national non-profits for years now, and this is one of the first books I suggest anyone who needs to create their own PowerPoint look to. Beyond Bullet points is accessable enough that the novice PowerPoint user can understand what's going on and use the lessons in his or her next presentation; it's also detailed and challenging enough that even an old salt like me can find things to learn and do. Don't be another person who stands on stage reading their PowerPoint, and don't let reading your slides distract the audience from your presentation; follow the suggestions in this book and wow your audience.
