Abstract: The invention provides a method of manufacture of a catalyst, the catalyst as such and its use in olefin oligomerisationand. The method for making an oligomerisation catalyst includes the steps of mixing alumina, silica, metal oxide, a template source; and effecting the deactivation of the Bronsted sites by masking them with metal ions, preferably either (i) during synthesis by directly adding the metal as ion in a one-pot or direct synthesis, or (ii) after intermidiate conversion to the H+-form by in turn either (ii-a) impregnating the latter with a metal salt, or (ii-b) thy-mixing a metal salt with it.

Abstract: A vehicle display device and method for elevating and rotating a vehicle configured to fit in a single car parking space, while simultaneously displaying messages through a connected electronic message display. The vehicle display device has a turntable allowing for three hundred and sixty degrees of rotation of the vehicle. The electronic message display can present multiple messages that are customizable and easily modified.

Abstract: One or more mobile vehicle display devices are provided herein. The mobile vehicle display device can include a trailer assembly and an outer housing. The trailer assembly can include a trailer frame, a turntable disposed on a portion of the trailer frame, a rotator adapted to rotate the turntable, and a wheel adapted to support the trailer assembly. Also, a method of using the mobile vehicle display device is provided herein.

Abstract: An emergency eye wash system having a support panel and a pair of brackets for holding two bag assemblies containing sterile and sealed eye wash solution. The bag assemblies are connected by hoses to a pair of nozzles mounted on a pivotal tray assembly. When the system is dormant, the tray assembly is in a vertical closed position. When there is an emergency, a user pulls on a pivotal handle to puncture membranes in the hoses and to lower the tray assembly to cause flow from the bags to the nozzles to the user's face.
