Abstract: An auto-injector for dispensing a predetermined dose of medicament is disclosed. The auto-injector includes a needle cover operative to engage an injection site. The needle cover is configured to move from a retracted position prior to a medicament dispensing operation to an extended locked position after the medicament dispensing operation. Any residual activation force remaining after the medicament dispensing operation is contained within the auto-injector and is not directed to the needle cover, thus attenuating, if not eliminating, any kickback effect.

Abstract: Disclosed is a self-priming portable powered device such as a tool, comprising a housing within which are defined a priming combustion chamber and a main combustion chamber, within which chambers during operation of the device there is a combustion of a combustible fuel and a combustion-supporting gas; and wherein a combustion event in the priming combustion chamber causes the formation of a mixture of fuel and combustion-supporting gas in the main combustion chamber which is compressed at a pressure above ambient pressure, subsequent combustion of the compressed mixture in the main combustion chamber acting on a work piston which, directly or indirectly, performs the intended task.

Abstract: An auto-injector for dispensing a predetermined dose of medicament is disclosed. The auto-injector includes a needle cover that is configured to move from a retracted position to an extended locked position. The auto-injector includes a first locking assembly to hold the needle cover in a locked retracted position and a second locking assembly to hold the needle cover in a locked extended position.

Abstract: Containers for automatic injectors and automatic injectors adapted for those containers are disclosed. The containers include structures adapted to retain and, optionally, cripple the needle of the automatic injector when the automatic injector is inserted into the container after use. Depending on the embodiment, an indicator may be included, either as part of the container or as part of the automatic injector, to indicate whether or not the automatic injector has been used. If the indicator is provided as a part of the automatic injector, a corresponding portion of the container may be formed of a light permeable material. The container may also include features, such as an eyelet over the closed end, designed to cushion the automatic injector. Cushioning and shock absorbing features may also be provided inside the container. A clip is also disclosed. The clip is designed to attach two or more containers together.

Abstract: Disclosed is a portable powered device such as a tool, comprising a housing within which is defined a combustion chamber (8) for combustion of a mixture of fuel and a combustion-supporting gas, which mixture is compressed so as to be subjected to a pressure in excess of the ambient atmospheric pressure prior to combustion, combustion of the fuel/combination-supporting gas mixture providing the power by which the device performs its intended task, and wherein the said combustion and/or a further combustive event provides the power to compress a successive fuel/combustion-supporting gas mixture, such that a successive cycle of operation of the device may be performed without requiring manual compression of a fuel/combustion-supporting gas mixture by the user.
