surplus computer equipment - Laboratory Accreditation

Laboratory Accreditation and Data Certification: A System for Success

Laboratory Accreditation and Data Certification: A System for Success

This book provides descriptions of current laboratory accreditation schemes and explains why these schemes fall short of assuring data purchasers that the data produced from accredited laboratories are always quality products. The book then presents a system for laboratory accreditation in conjunction with data certification that assures data purchasers their data are useful for the purposes for which they are intended. Simple quality assurance and quality control techniques, in addition to concepts of total quality management, are described and then applied to the environmental laboratory industry. This "System For Success" was developed from real problems and real solutions within the industry and represents an integration of proven techniques that offer a better way to ensure quality laboratory data is obtained. Laboratory Accreditation: A Workable Solution is a must for government officials, environmental professionals, independent environmental laboratories, hazardous waste disposal industries, chemical manufacturers, QA professionals, and testing laboratories.

Dectrac Position Fixing Unit Mk.19

Dectrac Position Fixing Unit Mk.19

Recently I stumbled across a dusty old shop run by three old boys, with pullovers that were more holes than actual knitting & industrial sized tartan Thermos flasks, that specialized in valves, radio spares and ex-RAF equipment. I'd not seen a shop like this since Proops fizzled out at the end of the 80's so I couldn't resist a look, or walking out with a suitably photogenic box of gubbins.

Having researched a little it seems that Decca developed the Dectrac system initially as a maritime aid in the mid 1940s, but the benefits of having an onboard navigation computer were realized by the RAF for use, I suspect, in it's longer range bomber aircraft such as the Canberra and the Vulcan. So, in the 60's Decca took a very large MoD order for Mk.19 units such as this, which were successful enough to be manufactured into the early 80's. Dectrac coverage was pretty much global, with a multitude of 'Chains' being set up across the 'friendly' World - not to be confused with the WWII 'Chain Home' early warning network. Chain 5B was for England, the earliest - being set up in 1946 and operating unitl 2000.

It is more than a little unsettling to think that in the event of M.A.D. - Mutually Assured Destruction - surviving RAF bomber crews were expected to consider England 'hot' [radioactive] and keep on going for somewhere remote such as the Pacific Islands, writing off their friends, families & country as dead. All out Nuclear War would in effect have reduced the entire Western Civilization to a few dozen aircrews stranded on islands and atolls living off survival rations and coconuts.

The Button

The Button

When I was a graduate student in the late '60's, a colleague in our group got hold of a surplus NORAD computer, probably dating to the '50's. It was a couple of racks full of transistorized logic cards, which we took apart and used the racks, the transistors, and the power supplies to build other equipment for our work. It was definitely out of date since by that date individual integrated circuits had replaced entire cards full of transistors. (By now the integrated circuits have replaced the entire racks [not including the power supplies and manual controls]).

This button was mounted on a panel on the computer. It has a guard around it so you can't lean on it by accident. From the text on the button we always considered it to be THE BUTTON, although there was never any documentation to that effect. I have never found a suitable use for it, even to control woodchucks.

Fortunately, it's no longer connected to anything.
