Abstract: The invention relates to a system 10 for conducting a sales mechanism over the internet in accordance with an embodiment of the invention. The system 10 comprises a sales platform 18 for vendors of items such as a real estate property, sales facilitators 16 to administer the sales mechanism, and buyers (also referred to as bidders 14) to interact for selling and buying the items offered for sale. The description to follow will refer to a particular application of the sales mechanism for offering for sale a real estate property; however, the sales mechanism may be utilised for offering for sale any tangible or intangible items that is able to be sold.

Abstract: A syringe assembly comprising a barrel for containing one or more medicaments, the barrel having a front outlet for allowing the expulsion of said one or more medicaments from the said barrel through said outlet, and a first stopper disposed in the barrel and axially moveable therein and defining a first volume in the barrel axially forwards of the first stopper and a second volume in the barrel axially rearwards of the first stopper. The first stopper has a two way valve that is moveable between a sealing configuration and an open configuration to selectively put the first volume in fluid communication with the second volume. The two way valve is moveable from the sealing configuration to the open configuration by an increase in fluid pressure in either of the first and second volumes.

Abstract: An injection device having an outer housing configured to receive a syringe. The syringe has a barrel for containing medicament and a needle in fluid communication with the barrel. The device further has a needle shield axially moveable relative to the outer housing between a needle covering position and a needle exposing position and a helical compression spring to bias the needle shield axially forwardly toward the needle covering position. A locking sleeve, axially movable relative to the outer housing between a non-locking position and a locking position, selectively limits axial movement of the needle shield. In a first configuration, the needle shield is axially slideable within the locking sleeve to permit rearward axial movement of the needle shield from the needle covering position to the needle exposing position.
