Although well known for many years in the world of organ building, they achieved wider notability in 2004 with their refurbishment of the Royal Albert Hall s Father Willis organ. Mander has completed several famous organs, chief among which is probably the 68 stop four manual and pedal organ in the Church of St. Ignatius Loyola New York City Church of St Ignatius Loyola , New York reportedly the largest mechanical action built to date by a British builder. Simon Preston said of this instrument It is difficult to do justice to this famous instrument in a couple of sentences suffice to say that to look at this beautiful instrument is to know the sound that will come out of it. In keeping with the modern fashion, new Mander organs are generally tracker action , which enables the player to give somewhat more expression and removes the delays which are inherent in many electrically actuated organs. The company was founded in 1936 by Noel Mander Order of the British Empire MBE , FSA 19 May 1912 18 September 2005 . An early setback was the loss of the organ he was working on, along with all his tools, in the first airstrike air raid of the Blitz in 1940. Ironically it was the rebuilding of church organs after the war which provided a firm foundation for the company. The firm is now run by John Mander, Noel Mander s son and pipe organs have been built and installed in Australia , Japan , Middle East , New Zealand , Scandinavia and the United States .

Italic title Four Organs is a work for four electronic organ s and maraca , composed by Steve Reich in January 1970. Music The four organs, harmony harmonically expound a eleventh dominant eleventh chord E D E F G A B , dissecting the chord by playing parts of it sequentially while the chord slowly increases in duration from a single 1 8 note at the beginning to 200 beats at the end. The process of increased Augmentation music augmentation is accomplished first by causing notes to sustain after the chord, and then notes start anticipating the chord. As the piece progresses, this deconstruction of the chord emphasizes certain harmonies. At the climax of the work, each tone sounds almost in sequence. A continuous maraca beat serves as a rhythmic framework. Reich describes the piece as the longest V I Cadence music cadence in the history of Western Music the v B D F and I E G B chords being contained within the one chord You ll find the chord in Claude Debussy Debussy and Thelonious Monk the Tonic music tonic on top and the Dominant music dominant on the bottom. ref Steve Reich Works 1965 1995 Nonesuch 79451 2, 1997 , interview with Jonathan Cott, p.33 ref He has cited the music of Perotin and other twelfth and thirteenth century composers as suggesting the technique of note augmentation used in Four Organs . For performances of the piece, Reich recommended using electronic organs with as plain and simple a timbre as possible, without vibrato, to avoid the sound of the instrument itself distracting from the harmonic and rhythmic aspects of the piece. Reich himself employed four Farfisa mini compact models. Performances Four Organs was first performed in May 1970 at the Solomon R.

Unreferenced date July 2008 Electrohydraulic forming is a type of Category Metal forming metal forming in which an electric arc discharge in liquid Yutkin effect is used to convert electrical energy to mechanical energy and change the shape of the workpiece. A capacitor bank delivers a pulse of high current across two electrodes, which are positioned a short distance apart while submerged in a fluid water or oil . The electric arc discharge rapidly vaporizes the surrounding fluid creating a shock wave. The workpiece, which is kept in contact with the fluid, is deformed into an evacuated die manufacturing die . The potential forming capabilities of submerged arc discharge processes were recognized as early as the mid 1940s Yutkin L.A. . During the 1950s and early 1960s, the basic process was developed into production systems. This work principally was by and for the aerospace industries. By 1970, forming machines based on submerged arc discharge, were available from machine tool builders. A few of the larger aerospace fabricators built machines of their own design to meet specific part fabrication requirements. Electrohydraulic forming is a variation of the older, more general, explosive forming method. The only fundamental difference between these two techniques is the energy source, and subsequently, the practical size of the forming event. Very large capacitor banks are needed to produce the same amount of energy as a modest mass of high explosives which is expensive for large parts. On the other hand, the electrohydraulic method was seen as better suited to automation because of the fine control of multiple, sequential energy discharges and the relative compactness of the electrode media containment system.

It works upon the theory of superplasticity , which means that a material can elongate beyond 100 of its original size. ref name Degarmo444 Degarmo, p. 444. ref Process To begin with, the material must have an ultra fine grain size. It is then heated up to promote superplasticity. For titanium this is around convert 900 C F abbr on and for aluminium it is between 450 520 C. In this state the material is not very strong so processes that are usually used on plastics can be applied, such as thermoforming , blow forming , and vacuum forming it may also be deep drawn . ref name Degarmo444 Advantages & disadvantages The major advantage of this process is that it can form large and complex workpieces in one operation. The finished product has excellent precision and a fine surface finish . It also does not suffer from springback or residual stress es. Products can also be made larger to eliminate assemblies or reduce weight, which is critical in aerospace applications. ref Degarmo, pp. 444 445. ref Lower strength required and less tooling costs. The biggest disadvantage is its slow forming rate. Cycle times vary from two minutes to two hours, therefore it is usually used on lower volume products. ref Degarmo, p. 445. ref Also materials must not be superplastic at service temperatures.

ISBN 0 88317 159 7 ref This might expand a cartridge to a new size, such as a wildcat cartridge , or just to the chamber of a specific gun. Fire forming a wildcat differs from the normal manufacturing process in that it relies on firing a loaded Cartridge firearms cartridge of differing dimensions than the chamber which it is being fired in. After fire forming, the spent case will take on the new dimensions of the firearm s chamber. Fire forming is the final process in creating a wildcat or an improved cartridge . There are two methods of fire forming. One method is to cold form a parent case using forming dies, creating some form of headspace , load the case and fire the cold formed cartridge in the chamber of the firearm. This first method is the most common and will create a wildcat cartridge. The second method is to fire form a factory cartridge by using its factory headspace to headspace on. The factory cartridge is then fired in the chamber of the firearm. This second method will create an improved cartridge. References references Parker O.

refimprove date April 2012 Explosive forming is a metalworking technique in which an explosive charge is used instead of a punch or press. It can be used on materials for which a press setup would be prohibitively large or require an unreasonably high pressure, and is generally much cheaper than building a large enough and sufficiently high pressure press on the other hand, it is unavoidably a batch process, producing one product at a time and with a long setup time. Various approaches There are various approaches one is to place metal plate over a die manufacturing die , with the intervening space evacuated by a vacuum pump, place the whole assembly underwater and detonate a charge at an appropriate height above the plate. For complicated shapes, a segmented die can be used to produce in a single operation a shape that would require many manufacturing steps, or to be manufactured in parts and welded together with concomitant loss of strength at the welds. There is often some degree of work hardening from the explosive forming process, particularly in mild steel . Tooling Tooling can be made out of fiberglass for short run applications, out of concrete for large parts at medium pressures, or out of ductile iron for high pressure work ideally the tooling should have higher yield strength than the material that is being formed, which is a problem since the technique is usually only considered for material which is itself very hard to work.
