High Rise Buildings
Historical Archives of the Zephinie Vertical Escape Chute Technology 
United Technologies - Otis Elevator 


The included documents prove that United Technologies Corp's European subsidiaries have backed of their multinational image guaranty the marketing the ZEC technology since 1975 , including installing the ZEC-ME in some of the taller buildings of Europe.

The evidence that this unique type of equipment have been marketed by a major American Corporation since 25 years in Europe  should collateral the evidence that we are talking about the kind of Mickey Mouse escape systems as so far mentioned by American media and wakeup the expected sense of ethic of eventually some American journalists to finally investigate the outrageous case of secret conflict of interests leading to blackout of the yet only available escape technology of public interest.  


Why the board of United Technology has banished in 1977_78  the ZEC technology  to be available to the American public , vetoing the initiative of the  OTIS Corp, American subsidiary to try to market the new technology in the USA,       

Obviously UTC have been obliged to take this American anti-public interest position under the pressure of compelling reasons.

UTC must be compelled reveal the secret.
Thousands have lost their lives.

Any company in the USA will give up to try the hundreds of millions potential market of a new exclusive technology 17 years secured by first class US patents, if not scarred to the point of forbidding to mention to the American Media that UTC was marketing this public interest technology in Europe.

 Manche d'Evacuatio OTIS

 This catalogue was first edited by the Evacuation Vertical Zephinie (EVZ)  company in 1974 .

Ascenter OTIS S.A.  acquired from Gerard Zephinie the exclusive license for the French territories  the very same day
that United Technologies Corp acquired the OTIS Elevator Corporation the 18 of December 1975 .

2 years later the United Technologies Corp. will veto the effort of Mr. Huber Faure President, at that time of the OTIS Elevator Corp to introduce the new technology in the USA
United Technologies Corp never have given, as so far, an official reason for forbidding OTIS Corp to market the ZEC in the USA.  However the OTIS Elevator Corp  were authorized to market the ZEC technologies in all countries, but the USA.

In September 1976 Zardoya OTIS  subsidiary of United Technologies in Spain had acquired the exclusive license of the ZEC for the Spanish territories.

Archive documents show that OTIS - UTC has offered to market the ZEC Technology in many countries, Zephinie will not accept in regard to the unfair boycott of the new technology,  imposed by the Board of United Technologies

It is important to mention that the ZEC-SE never has been authorized by the inventor Zephinie to be installed in any high-rise building as it shows the the photography above.
25 years ego we have analyzed and tested why any Single type Chute can be used safely over 30m (100ft) in public or business buildings.

Only inexperience and credulity can eventually motivate peoples to claim in 2001 the possibility to eventually evacuate 35 stories building with  some Chutes of the "single" type    

The February 1974 demonstration was exclusively to introduce the the new technology to the international press

  The Zephinie High-Rise Vertical Escape Chute or ZEC- Multiple Entry is completely fire code enclosed and absolutely impossible to report in a spectacular manner like the system called ZEC -Single Entry    

The Catalogue was including the definition of the ZEC-ME
As reproduced below.

This particular type of installation show that a 2 units stairway can be converted in  5 units stairways-ZEC using only 19% of the total area of the stairway
