Inspecting and Testing (Balance assembly is removed from movement) • Inspect pivot (suspension) wire for distortion, corrosion, breakage. • Balance should appear to float between frame. Top and bottom distance. • Balance spring should be proportional and not distorted in any way. • Inspect jewels for cracks and or breakage. • Roller pin should be centered when viewed from front. (beat) • Rotate balance wheel three quarters of a turn (270°) and release. It should rotate smoothly with no distortion and should oscillate for several (3) minutes. Otherwise it needs attention. Floating Balance cont. Cleaning • Make sure the main spring has been let down before working on movement. • Use non-aqueous watch cleaner and/or rinse. • Agitate in cleaner/rinse by hand or briefly in ultrasonic. • Rinse twice and final in naphtha, Coleman fuel (or similar) or alcohol. • Allow to dry. (heat can be used with caution – ask me how I would do it.) Lubrication • There are two opinions. To lube or not to lube. • Place a vary small amount of watch oil on to the upper and lower jewel where the pivot wire passed through the jewel holes. -

Students will investigate the mechanics of comics storytelling through a series of exercises designed to deconstruct the comics language. Popular All Time. In this course students explore the fundamentals of animated movement, timing, and materials through various animation techniques, including working directly on film, drawing on paper, pixilation, cut-out animation, and modified-base processes. The instructor encouraged student participation in class. Key concepts and important information are highlighted, and the reader-friendly layout reflects exactly the type of question you will encounter, making these volumes the perfect revision aid for all types of case-based examination.

History of Escapement Mechanisms
Journal of Mechatronics, Automation and Identification Technology Vol. 3, No.2. pp. 8-12 History of Escapement Mechanisms Miša Stojićević, Branislav Popkonstantinović, Ljubomir Miladinović, Ivana Cvetković Faculty of Mechanical Engineering, Belgrade, Serbia Faculty of Mechanical Engineering, Belgrade, Serbia Faculty of Mechanical Engineering, Belgrade, Serbia Innovation Centre of the Mechanical Faculty Belgrade, Serbia [email protected], [email protected], [email protected], [email protected] Abstract—This paper describes a history of development one of the most important part of mechanical clock – escapement mechanism. Escapement mechanism is a device designed to maintain a constant average speed of the escape wheel, by allowing it to rotate to the desired angle at certain impulse of time. While doing that it simultaneously support the oscillations of the pendulum or balance spring, by compensating for friction losses and air resistance. 7 century long history of escapement mechanisms, from 13th century verge mechanism up to modern-day escapements that can be found in luxury watches, will be shortly presented. Through lives of famous clockmakers and their achievements in field of making escapement mechanism will be given a new insight in science of time keeping - horology. Keywords— escapement, mechanism, history, watches, clock I.

It can be also said that escapement is a device which could be worn in a pocket or purse (Ger.: that transfers energy to the timekeeping element (the taschenuhr), was constructed in Nuremberg by "impulse action") and allows the number of its watchmaker Peter Henlein, (1485-1542) oscillations to be counted (the "locking action"). -

The Journal of the International PMC Guild Mitsubishi
fusion seventeen 17 fusion 2011 /3 The Journal of the International PMC Guild Mitsubishi Materials, which manufactures PMC, recently sponsored the largest sur- vey of the metal clay community, and the results are in. In this issue of Fusion, we present and analyze the results. But first, it’s important to under- stand the scope of the survey. In an at- tempt to be as comprehensive and com- plete as possible, Mitsubishi enlisted the help of many organizations and individuals to distribute the survey, including retailers involved in the sale and promotion of metal clay, as well as advocacy and member groups, such as the PMC Guild, and others. Their efforts proved enormously successful. More than 2,400 individuals responded to the survey, which represents 10–15% of the metal clay community in North America. While that percentage may appear small, it’s actually quite large, and offers Mitsubishi a rare opportunity to glean significant data from the results. By and large, the survey confirmed what the PMC Guild has known, or believed, for many years. This data offer proof, said Tim McCreight, Communications Director for the Guild. “The survey confirmed my sense of the community. My understand- ing of the demographic — the age, education, gender, and so on — is what we found to be the case. There is value in knowing this, particularly for people who have not been involved in the metal clay community as deeply as some of us have,” he said. “The very fact of the high response rate is again something I predicted but a fact that should grab the atten- tion of vendors, manufacturers, and publishers.
