Abstract: The present disclosure relates to an injector device having a housing, a cartridge with a reservoir for medicament, a needle unit with a needle, and a needle sleeve rotatably mounted to the housing about an axis. Prior to use of the injector device the needle is sealed from the reservoir, and at least one of the needle unit and the cartridge is axially slidably mounted to the housing. The needle sleeve includes an engagement member arranged to engage the needle unit and/or the cartridge. The engagement member is adapted such that rotation of the needle sleeve moves the needle unit and/or the cartridge in an axial direction to move the needle into fluid communication with the reservoir.

Abstract: The present disclosure relates to an injector device comprising: a housing having a distal end and a proximal end; a medicament cartridge disposed within the housing; a needle unit comprising a needle, the needle unit being disposed in the distal end of the housing; and a button disposed in the proximal end of the housing, the button being configured to move the cartridge onto the needle unit to fluidly connect the needle with the cartridge when, in use, the button is pressed from an initial position into a depressed position.

Abstract: An arrangement that provides a semi-automatic tension adjustment of an endless cutting chain on a guide bar of a chain saw as the links of the chain wear with use. A specially designed cam biases a tensioner pin to continuously force the guide bar away from the drive sprocket on the engine chassis to tension the chain. A knob on a clutch cover assembly attached to the engine chassis can be tightened to force two high friction surfaces together to lock the guide bar in a tensioned position, or loosed to release the guide bar to seek a proper tensioned position. An override lever on the face of the clutch cover assembly moves in a channel with peripheral nomenclature that indicates when the cutting chain should be replaced. The entire arrangement is self-contained and does not require any tools to function.
