  • Practical Implementation of the Stream Function Method for Design of Arbitrary-Geometry Gradient Coils
    Practical Implementation of the Stream Function Method for Design of Arbitrary-Geometry Gradient Coils R. A. Lemdiasov1, R. Ludwig2 1Insight Neuroimaging Systems, Worcester, MA, United States, 2ECE Department, Worcester Polytechnic Institute, Worcester, MA, United States Introduction Over the past several years a variety of theoretical design methods for the construction of gradient coils have been developed. For instance, in [1] D. Green et al. minimize a weighted combination of power, inductance, and the square difference between actual and desired field. Representing the current as a Fourier series they find optimal coefficients that minimize the cost function. Our work is a continuation of last year’s research reported in [2]. In this paper we describe an alternative implementation of a stream function method to design gradient coils. Using this method we are able to determine the current distribution to achieve a prescribed magnetic field distribution in the Region of Interest (ROI) that is largely independent of the shape of the current-carrying surface. We will demonstrate the successful implementation of our approach as well as experimental results. Theory As mentioned above, a cost function Φ can be introduced in the form K Φ = 1 ()() ()− ()+ 2 +α ∑W rk Bz rk Bdes,z rk Boff ,z Wmagn (1) 2 k =1 () () where W r is a weight function, BZ is the z-component of the total field, Bdes,z r as well as Boff,z are the z-components of the desired and offset magnetic field, and α Wmagn is magnetic energy with being a weight coefficient. In (1), the first term denotes the square deviation of the magnetic field from the prescribed field, and the second term is the magnetic energy of the coil.

  • Types of Tap
    Types of Tap HAND TAPS ISO 529 These are straight flute general purpose tools which can be used for both machine or hand tapping. They are generally the most economical tool for use on production runs, but are best on materials that produce chips, or where the swarf breaks readily. Where deep holes are to be tapped, in materials which produce stringy swarf, serial taps may be needed, especially for coarse threads. ISO 529 hand taps can be supplied in sets of three; bottom, second and taper leads, or individually. BOTTOM TAPS have a chamfer (lead) of 1–2 threads, the angle of the lead being around 18 degrees per side. They are used to produce threads close to the bottom of blind holes. SECOND TAPS have a lead of 3-5 threads at 8 degrees per side. They are the most popular and can be used for through holes, or blind holes where the thread does not need to go right to the bottom. TAPER TAPS have a lead of 7-10 threads at 5 degrees per side. The taper lead distributes the cutting force over a large area, and the taper shape helps the thread to start. They can therefore be used to start a thread prior to use of second or bottom leads, or for through holes. IMPORTANT NOTE ON TERMINOLOGY! In the U.K. bottom taps are often referred to as ‘plugs’. In North America second taps are often referred to as ‘plugs’! This can easily lead to confusion. To avoid problems when ordering it is best to use the terms bottom, second and taper.

  • Revolving Windsor Chair
    16 Revolving Windsor Chair A few years ago it fell to me to write a story about Thomas Jefferson in a chess match with his slave Jupiter. This venture led to a play on the same subject, as well as research into the physical objects used as metaphorical vehicles for the ideas. In this regard, Jefferson makes it easy for us. One of the more obvious physical items is the revolving Windsor chair used by Jefferson when he was working to draft the Declaration of Independence in 1776. Having seen a picture of the chair in its surviving form and an- other picture of a re-creation of it, I undertook to make a similar one to use on stage. My version differs from the original in the use of a steam-bent arm rail rather than a sawn and carved one, because I could make a bent arm faster than a sawn one. Making this swivel Windsor is in some ways easier than making a normal one, in that the seat is circular rather than a sculpted outline. There are a lot of parts and processes to a Windsor chair, but with the exception of hollowing the seat, you have already seen how to do them all. Windsor chairs, as the name suggests, are of English design. Windsor chair-making in England centered around the town of High Wycombe, but the chairmaking did not begin in town. Out in the woods, workers called chair bodgers felled, split, and turned the beech legs on their springpole lathes, then sold these legs to chairmakers in town.

  • Making Stub-Tenon Doors
    Making Stub-tenon Doors The stub-tenon joint will never be the super- hero of your joinery arsenal because it doesnʼt have the stuff necessary to be a strong joint. The mating parts are short (hence the “stub” moniker) and itʼs housed on only two sides: the face cheeks of the tenon. There is sufficient glue surface, but the cross-grain orientation compromises the glue joint. In the pantheon of woodworking joints, the stub-tenon joint may be more accurately described as a 90-pound weakling. But even so, this can be sufficient for smaller, lightweight doors that donʼt take a lot of abuse. For example, you wouldnʼt choose this joint for kitchen cabinet doors or built-ins for the kidsʼ playroom. But itʼs OK to use a stub-tenon door for a vanity cabinet or for a project thatʼs built as much for looks as it is for service. Once a door weighs more than four or five pounds, or is larger than 18" x 24", you must abandon the stub-tenon joint for a more substantial one. Mortise-and-tenon construction, dowels, loose tenons and even biscuit joints are superior choices for larger, heavier doors. So why use a stub-tenon joint? Well, itʼs easy to make because it requires a minimal amount of setup time regardless of the method you choose to cut the joint. Itʼs usually cut with a router in a table or on the table saw using a stack dado set. The ease of setup is because the same groove thatʼs cut to receive the panel doubles as the groove for the stub tenon.

  • Stub Tenon & Groove
    he stub tenon and groove joint is Tquick and easy to cut. And the entire joint can be made on the table saw. It’s made by first cutting a groove on one edge of each stile (the vertical pieces) and rail (the horizontal pieces). These grooves hold a center panel and short, “stub” tenons cut on the ends of just the rails. The depth of the groove (and the length of the tenon) can vary depending on the type of panel you plan on using. A 1 /4"-deep groove works fine with a ply- wood panel. But if the panel is solid 3 wood, you should use a /8"-deep groove. Why the difference? It has to do with how the frame is assembled. I glue a plywood panel into the groove so it becomes a part of the GROOVES joint. That way I can get away with a shorter tenon.
