This paper was prepared for submission to the Thirteenth Pulse Power Symposium in Buffalo, NY, June 19-22, 1978. Stapled at upper left corner. Results were to be presented on the design and testing of a pressurized gas blown spark gap switch capable of high repetition rates in a burst mode of operation. The switch parameters which had been achieved were as follows: 220-KV, 42-kA, a five pulse burst at 1-kHz, 12-ns risetime, 2-ns jitter at a pulse width of 50-ns. The construction of the coaxial spark gap is illustrated in Figure 1. The spark gap bolts on to the lower end of a 5.2 coaxial water Blumlein and was designed to switch the mid conductor to ground. The Blumlein's mid conductor feeds through a polycarbonate resin insulator which interfaced between the water and the high pressure gas and become the switch's anode. From Wikipedia: A spark gap consists of an arrangement of two conducting electrodes separated by a gap usually filled with a gas such as air, designed to allow an electric spark to pass between the conductors. When the potential difference between the conductors exceeds the breakdown voltage of the gas within the gap, a spark forms, ionizing the gas and drastically reducing its electrical resistance. An electric current then flows until the path of ionized gas is broken or the current reduces below a minimum value called the "holding current". This usually happens when the voltage drops, but in some cases occurs when the heated gas rises, stretching out and then breaking the filament of ionized gas. Usually, the action of ionizing the gas is violent and disruptive, often leading to sound (ranging from a snap for a spark plug to thunder for a lightning discharge), light and heat.…

Hardcover. Zustand: Fine. No Jacket. lxvii, 760 pages : illustrations ; 29 cm OCLC 52073501 This reprint of the first edition of Sweet's Catalog commemorates the 90th anniversary of the Sweet's business."--Foreword ; "In offering to the public, and especially to the architects of the United States, the first edition of Sweet's Indexed Catalogue of Building Construction, the publishers have realized at the very outset the importance of stating clearly, first, what the book is, and secondly, the reasons for commending it to the architectural profession for their use and support. .to explain in a few words the character and purpose of the work, . a embodied in these first successful efforts toward a really scientific standard catalogue and index of building materials and construction. Let the matter be looked at entirely from the point of view of the architect. For a period of a dozen years, every possible method of collecting, sorting, classifying, filing and indexing all the catalogues and circulars of building materials was conscientiously given a fair trial, and after a thorough test, every method was just as conscientiously abandoned. They were abandoned because they did not work well in the specification room. They were not practicable. Everything was tried, arrangements of shelves, bookcases, pasteboard boxes, filing cases, patent binders, filing cabinets, cases of drawers, indexing schemes and " index- rerums. " At first, all the big books were put together in one place and all the little books in another place; and then all the big and little books were mixed up together, and indexed according to subject. Some had four pages, and some had four hundred pages. Barely two were of the same shape or superficies. The little ones would not stand up, and could not be gotten at when laid flat. Another elaborate system was introduced, and a voluminous cross-index started, but the big books contained too much useless matter, and the little books got lost or mislaid or could not be found just when wanted. Then the writer decided, after much time and expense, that the present system of publishing and distributing catalogues, as far as the architect is concerned, might be rightly termed " The Catalogue Delusion, " and that the only solution of the problem must lie in a scientific standard catalogue and index of building materials and construction, gradually developed toward an ideal result by the co-operation of manufacturer and architect. Briefly, then, what is Sweet's Indexed Catalogue of Building Construction? It is a scientific catalogue book system ( a volume or series of volumes) , as easy to refer to as a dictionary, consisting of groups of catalogues from which as much unnecessary matter as possible has been eliminated, carefully indexed and cross- indexed, and sent out gratuitously by the publishers to every architect of good standing. Each catalogue in the work is organically arranged in its parts. It proceeds in a regular order from fact " A " to fact " Z " . Illustrations of a certain class are all grouped and arranged according to some obvious plan. " Literature " and " mere writing " are omitted, as an architect has no time in his office for either."; authors and compilers include Wm. Martin Aiken, Claire Allen, J. M. Baillie, Charles I.
