Design of a Tree Pruning Device
CAPSTONE DESIGN COURSE Design of a Tree Pruning Device Design Team Garth Baker, Pete Colantonio, Dmitry Layevsky Ryan Provencher, Ryan Rafter Design Advisor Professor Greg Kowalski Course Instructor Professor Greg Kowalski Department of Mechanical, Industrial, and Manufacturing Engineering Northeastern University Boston, MA 02115 Design of a Tree Pruning Device Design Team Garth Baker, Pete Colantonio Dmirty Layevsky, Ryan Provencher, Ryan Rafter Design Advisor Prof. Greg Kowalski Abstract The initial specifications of this design project were to design a pruning device that could cut through a three-inch diameter branch that is twenty-five feet above the ground in a reasonable amount of time using a waterjet-cutting device. Additional requirements include that the device have a competitive cost and be safe and easy to use. The team determined that the use of waterjet cutting technology was an infeasible design concept to meet these requirements, because it would take almost two hours to cut through a three inch branch using a pressure washer capable of 3500 psi. To cut a three-inch diameter branch in a reasonable time would require a pressure above 30,000 psi. A shearing device that would be powered by a hydraulic piston was selected as a better and more feasible alternative design solution. The shearing device we designed has hardened steel blades from a Corona® clipper product, and utilizes a hydraulic piston attached to a 29-foot telescoping pole, which is mounted to a tripod .. A telescoping pole, made of Thorne!® carbon fiber and reaching twenty-five feet, is required to meet the second design requirement. -

Making a Skull Ring
Making a skull ring The first people to utilize the lost wax process is unknown as it is shrouded in history. It is well documented that it has been used for thousands of years to produce objects in metal which could not be produced any other way, due to the complexity of their design. The lost wax process allows anything that can be modeled in wax to be accurately transmuted into metal. Most fine jewelry made from gold and sterling are made using lost wax casting as it produces the highest detail The Wax Models are placed in a Plaster Mixture which then aloud to harden. Once the plaster mixture (investment) has set hard, the flasks are placed in a kiln, slowly heated to between 1000 and 1250 degrees F, and held at that temperature until all wax residues have disappeared. The place where the wax was is now a void, hence the "lost wax" designation for this process. The metal is then melted in a metal furnace and the molds are filled with liquid silver by hand while the mold is still very hot. The flask is then allowed to cool and the investment mold is broken away revealing the metal piece. This process faithfully reproduces every detail of the original wax as well as the gates and vents, which must latter be cut off with a jeweler's saw. http://davescustomskulls.com/MAKING_OF_A_SKULL_RING.html (1 of 7) [10/27/2007 8:07:45 AM] Making a skull ring After cutting away the Silver Tail-(Sprue) the Hand Finishing Process begins with the Many different Steps shown below to BRING final Details and a Mirror Finish to the RING surface. -
The Diamond Glass Companies of Montreal, Canada
The Diamond Glass Companies of Montreal, Canada Bill Lockhart, Beau Schriever, Bill Lindsey, and Carol Serr The Diamond Glass Co. and Diamond Flint Glass Co. were two in a series of Canadian companies (headquartered in Montreal) that began with the Excelsior Glass Co. in 1879 and culminated as Domglas in the 1990s. This chapter deals with the first four firms during the 1879-1913 period (see the Dominion Glass section for the later companies). None of the glass houses used manufacturer’s marks on bottles, but all of them left embossed jars that can be traced to them. The Diamond Flint Glass Co. also made – and marked – insulators. Histories Excelsior Glass Co., St. Johns and Montreal, Quebec (1879-1883) William and David Yuile acquired control of the bankrupt St. Johns Glass Co. at St. Johns, Quebec, in 1878. They renovated the factory and incorporated in April of the following year as the Excelsior Glass Co. The plant made fruit jars, a general line of bottles, and insulators. Unhappy with the location, the brothers moved the factory to Parthenais St., Montreal, in 1880. The new plant produced prescription ware, fruit jars, and some tableware. The firm reorganized in 1883 as the North American Glass Co. (King 1987:67-70). Figure 1 – Beaver Goblet (Sean George Pressed Glass & Goblets) Toulouse (1971:189) told a slightly different story. He claimed that the Yuile brothers “had taken over the Foster Bros. Glass Co. Shortly after it was founded.” They renamed the plant the St. Johns Glass Figure 2 – Beaver band Co. in 1875 and the Excelsior Glass Co. -

Piece Mold, Lost Wax & Composite Casting Techniques of the Chinese Bronze Age Behzad Bavarian and Lisa Reiner Dept. of MSEM College of Engineering and Computer Science September 2006 Table of Contents Abstract Approximate timeline 1 Introduction 2 Bronze Transition from Clay 4 Elemental Analysis of Bronze Alloys 4 Melting Temperature 7 Casting Methods 8 Casting Molds 14 Casting Flaws 21 Lost Wax Method 25 Sanxingdui 28 Environmental Effects on Surface Appearance 32 Conclusion 35 References 36 China can claim a history rich in over 5,000 years of artistic, philosophical and political advancement. As well, it is birthplace to one of the world's oldest and most complex civilizations. By 1100 BC, a high level of artistic and technical skill in bronze casting had been achieved by the Chinese. Bronze artifacts initially were copies of clay objects, but soon evolved into shapes invoking bronze material characteristics. Essentially, the bronze alloys represented in the copper-tin-lead ternary diagram are not easily hot or cold worked and are difficult to shape by hammering, the most common techniques used by the ancient Europeans and Middle Easterners. This did not deter the Chinese, however, for they had demonstrated technical proficiency with hard, thin walled ceramics by the end of the Neolithic period and were able to use these skills to develop a most unusual casting method called the piece mold process. Advances in ceramic technology played an influential role in the progress of Chinese bronze casting where the piece mold process was more of a technological extension than a distinct innovation. Certainly, the long and specialized experience in handling clay was required to form the delicate inscriptions, to properly fit the molds together and to prevent them from cracking during the pour.
