Christmas tree ornaments

The ribbon machine employs a puff-and-blow method to make incandescent light bulb envelopes (1200/min), dashbulb envelopes (2000/min), Christmas tree ornaments, and the like (Fig. 15). For larger articles, the turret chain machine also uses the puff-and-blow method, but produces less cuUet and uses individual glass gobs rather than ribbon. 

Christmas tree ornaments Can cause foreign body effect or choking hazard. Antique or foreign-made ornaments may be decorated with lead-based paint. 

During the development phase of a new product that used tape casting for a very low-tech product—Christmas tree ornaments—one of the authors and his partner in the venture, Dan Shannon, decided to use an Aclar film for as many casts as possible. The carrier, after the product was stripped, had a residual film on its surface that had to be removed before it could be used for the next series of casts. We therefore decided to run the machine in reverse and rub the surface clean using ethyl alcohol and labwipes. This process required both of us, since the reverse speed on the machine was "full throttle" and we could barely keep up. As a matter of fact, we resembled a scene out of a well-known "I Love Lucy" episode in a candy factory. The entire process took several hours every week and in the long run was not very cost effective. The moral of the story is twofold first, determine whether re-use of the carrier is going to save any money, and second, make sure the speed of the machine in reverse can be controlled ... 

Imported articles that are intended for decorative use rather than as toys may contain lead paint. Christmas tree ornaments or other types of miniatures or knickknacks may expose small children to lead if they are chewed on or mouthed. For a more detailed discussion about lead in paint and dust, see Chapter 10, For a discussion of how to identify and control lead paint hazards, see Chapters 11 to 13. 

A hydrocarbon structure can serve as a framework to which various heteroatoms can be attached. This is analogous to a Christmas tree serving as the scaffolding on which ornaments are hung. Just as the ornaments give character... 

Development of weed resistance to triazine herbicides has necessitated alternative weed control strategies. Rotation of triazines with other herbicides and combining triazines with other chemistries has been effective in ornamentals and Christmas tree plantations (Van Himme, 1989). Supplemental treatments in Christmas trees have been effective, using directed sprays of phenoxy herbicides or glyphosate before resistant weeds mature and produce seeds. Weed resistance from triazines is not a problem in most forest settings where the herbicide is applied only once or twice in a rotation, since 1 or 2 years of herbaceous weed control normally ensures survival and eventual dominance by conifers. When the conifer canopy closes, virtually all herbaceous vegetation is shaded out for some decades hence resistant weeds, if present, fail to survive from one generation to the next. 

Simazine is widely used for preemergence control in field-grown nursery stock in North America. Selective use in container nurseries also has been demonstrated (Ahrens, 1972 Fretz, 1974 Wadsworth, 1975 Bing, 1983). It is less widely used in container-grown nursery production because of potential leaching (Elmore et al., 1976), but is especially effective when applied in the fall or winter to control winter annual weeds in containers. Simazine currently is registered in the United States for 50 species of woody ornamental nursery stock and Christmas trees. Tables 18.1 and 18.2 list selected species of conifers and deciduous ornamental plants, respectively, and their observed tolerance to simazine at rates of 2.2-3.3kg/ha. Information for these tables was obtained from personal observations and the literature, including those references by Ries et al. (1959) Ahrens (1961) Ticknor (1972) and Schubert et al. (1986). 

So, this text was pieced together like ornaments on a Christmas tree, one piece at a time and placed strategically on the proper branches. When the framework was not inclusive enough to accommodate new facts, then the framework was expanded. This process continued for nine years. 

As a result, most people do not try to use truly general energy balances, but use simplified versions appropriate for special problems. I find this specialization reminiscent of a Tibetan painting that hangs on the wall of my study. The top of the painting shows the Buddha of the Yellow Cap, sitting like a star on a Christmas tree. Other manifestations of the god are spread out below him like the tree s ornaments. These demigods are vividly represented. Some are ferocious, some look ineffective, others seem kind and approachable. 

Caribbean island I visit is a Christmas ornament. They re little treasures that come in all forms, from fish to palm trees. Most are handmade, and they re inexpensive and easy to carry back. Better yet, when they re displayed on the tree each year they re great conversation pieces that help us remember all the wonderful memories.
