[edit] James Dyson is not Sir James dyson

This is the second time I have removed 'Sir' from this article. James Dyson has a CBE not a KBE. Only people with a KBE are addressed as Sir.

James Dyson was knighted in the 2007 New Year's Honours...

"Knights Bachelor - James Dyson founder and chairman, Dyson, services to business"

"Knighthood for Dyson"

Strictly speaking, until the completion of the award ceremony, either by the Queen or an appointed deputy, James Dyson can't officially use the title "Sir" nor "KBE". So, strictly speaking he should not be referrred to in this article as carrying that title. The press also repeatedly get it wrong time and again and this argument also rears its head on Wikipedia just about every time an award is made! —The preceding unsigned comment was added by M100 (talk • contribs) 13:31, 30 December 2006 (UTC).

The 'rule' of not using the title & postnominals until after they have been conferred at an investiture was abolished in 1971; the modern convention permits useage of the prefix and appropriate letters as soon as the announcement has been made Official by publication in the "London Gazette".

[edit] Other

I removed the clause "although this is tempered by the new jobs in Malaysia" because I think it violates NPOV -- it sounds like apologism for Dyson. But if anyone disagrees with me, feel free to change it back. Brainhell 01:40, 10 February 2006 (UTC)

[edit] 5172 prototypes

The 5172 prototypes, even taken over an extendezShnbwrhd development period of 13 years (1970-1983) is more than one prototype per day. The *only* source for this overhyped statistic is James Dyson himself. Only a fool would believe this to a true numeration of the prototypes. M100 19:04, 27 March 2006 (UTC)

I suppose they could have been working on more than one prototype at once. --Chiklit (talk) 19:55, 27 March 2008 (UTC)

[edit] Amway CMS2000

Amway had a very similar vacuum cleaner in the 1990's, called the CMS2000. Does anyone know whether they stole the idea from James Dyson, was it licensed, or was there some legal loophole? -- Matthew 1130 12:12, 20 January 2007 (UTC)

Amway brought out a cyclonic vacuum cleaner which copied several of James Dysons ideas, see Against the Odds: An Autobiography by James Dyson, Page 178. I'm not sure of the model but it came out in the late 1980's. A lengthy legal battle followed (more than three years) which was resolved by making Dyson a licencee and keeping the Amway cleaner on the market -SmokeySteve (talk) 05:33, 14 March 2008 (UTC)

[edit] Inventor of dust-extraction cyclone was.. who?

It seems to be a household adage that 'Dyson invented the cyclone' - Yet, these devices are used extensively in industry for separating dust and gas. My own (brief) research seems to indicate the existence of (hydro)cyclone-related patents dating back as far as the 1890's, though these may not have covered dust-extraction uses. Does anyone have the lowdown on this? When, and by whom, was the dust-extraction cyclone invented?

(I became interested in this topic when a few years back, I was aksed to design some Flash animations explaining the operation of just such an industrial plant. The question, 'Do you have to pay royalties to Dyson?' inevitably arose. The answer was No.) —Preceding unsigned comment added by Anteaus (talk • contribs) 18:52, 27 January 2008 (UTC)

[edit] bagless vacuum

Dyson isn't even close to inventing the 'first bagless vacuum'. Rexair was selling one in the 1929. I'm removing this. Also "Dyson scientists were determined to create vacuum cleaners with even higher suction. It was discovered that a smaller diameter cyclone gave greater centrifugal force" is spurious. The cut point of a cyclone is simple physics and wasn't discovered by Dyson scientests. This article still reads like a promotional brochure.--Praguestepcihld (talk) 07:26, 2 March 2008 (UTC)
