Abstract: A multi-floor building construction system for progressively constructing floors on load-bearing means of a foundation as the occupational need to do so arises and while sub-floors can be occupied. A permanent roof structure is displaceably supported over an uppermost floor of at least an upper one of one or more occupational floor spaces. Extensible load support means is secured in the roof structure until the completion of the mufti-floor building. The extensible load support means rests upon the uppermost floor to support the total load of the permanent roof structure. The extensible load support means is extendible downwardly to push against the uppermost floor to raise the permanent roof structure. Adjustable hoisting means is secured inside the permanent roof structure for lifting floor sub-assemblies fabricated in the construction zone using the extensible load support means while simultaneously raising the permanent roof structure.

Abstract: A multi-floor building construction system and method for progressively constructing floors on the building, as the occupational need to do so arises and while some floors can be occupied, is described. A permanent roof structure is displaceably supported over at least an occupational first floor space constructed on the foundation. Extensible load support elements are secured in the roof structure and adapted to rest upon the load-bearing means to support a total load of the permanent roof structure. The extensible load support means are operated in synchronization. Extensible occupants elevators service the occupational floor space. A wall enclosure is secured inside and about the permanent roof structure.

Abstract: The present invention generally relates to control mechanisms and more specifically to a control mechanism which is adaptable to a steering wheel of a vehicle. Most control mechanisms of auto-piloting systems which must be installed on existing vehicles usually require more specific parts and more expensive installations. The control mechanism according to embodiments of the present invention includes components readily installable into the cabin of an existing vehicle and involves elements sandwiching the steering wheel of the vehicle which are operatively mounted to a motoring assembly actuatable by the user of the vehicle.
