there are talks of interest for just about everyone who works in the Plastics industry or in a lab.
In addition to the technical sessions, SPE conducts a full schedule of its well-known seminars, featuring some of the world's best experts (people like Glenn Beall, Chris Rauwendaal, Bill McConnell, Bob Dealey, Norman Lee, and Jordan Rotheiser) teaching one-, two, or three-day classes.
On Sunday evening, there is a "Fun Walk" and free Opening Reception, sponsored by the SPE Foundation, to introduce ANTEC attendees to the Foundation and the projects, including scholarships, which it supports.  During the week, there is also an exhibit area, free for conference attendees, with companies showing their wares for all aspects of plastics technical equipment, materials and chemicals.
For Spouses and Companions, there's a full schedule of activities; this year's included visits to the Texas Book Repository (where Lee Harvey Oswald was when he shot JFK); a city tour of Fort Worth, and a visit to Southfork Ranch (of the TV Series "Dallas") and the Dallas Mansions.
Finally, the week is capped by the prestigious Awards Luncheons and the Presidents' Reception on Wednesday evening.  The reception, a dress-up affair, marks the transition from one SPE President's administration to another and is the social highlight of the week.

This month we are going to visit Recovery Plastics International. We will have the  opportunity to see a unique process of recovering the usable plastic for discarded items like old cars. We fill that this should be a very informative event.
We are finishing the details for our 5th annual golf outing. We are planning to have it during mid-July. If you have any suggestions please contact me or one of the other board members. We will be sending a flyer with the details.
This will be the last newsletter until September so I would like to wish you all a great summer. And for those of you that are non-golfers we will look forward to seeing you in the fall.
Thanks,
Brent Strong
President
Great Salt Lake Section

Designing injection molded bosses with gussets:  Most of designers have had occasion to design a part with deep bosses supported by angled gussets.  (We'll define, for the purposes of this discussion, a deep boss as one that's at least four diameters high--four times as high as it is wide.)
One of the major concerns is the side loads which may be applied to the boss (if your boss doesn't have side loads, consider yourself lucky).  To help the boss handle those loads, many designers add small triangular gussets to the base of the boss, where the boss joins the wall.  Often times, four gussets are used:  the spacing is nice, it's easy to draw and doesn't use much material.
Wait a minute, though!  Recent research has shown that using a small number of gussets (four or less) can actually reduce the strength of the boss rather than enhance
