Head for an injection gun for animals or the like

A laundry machine having an agitator shaft rotatable backwards and forwards by an electronically controlled electric motor when in a washing mode and continuously in one direction when in a spinning mode has the agitator shaft connected to an interconnecting member spaced radially from its axis engageable with a connector for a concentric spin tub shaft to carry the spin tub with it when in the spin mode. The connection between the agitator rotating system and the spin tub rotating system are effected through an energy absorbing device which absorbs energy resulting from the change in relative speeds necessary to achieve speed equalization between the two systems.

Speed equalizing means and/or laundry machines incorporating the same

The subject matter relates to an applicator for applying matter to be applied, such as vaccine, to animals. The applicator includes an applicator head which incorporates a chamber and needle. The needle is at least partially surrounded by a generally elongate proboscis or cover which is capable of axial movement over and relative to the needle. A reservoir for matter to be applied or vaccine, is provided and is attached to the applicator head. Valving connects the chamber with the needle and also connects the reservoir with the chamber. Predetermined axial movement of the proboscis or cover relative to the needle opens the valving between the needle and chamber and allows matter within the chamber, such as vaccine, to be passed from the chamber through the needle. The chamber is provided with a movable wall and actuating means connected to a trigger. On the trigger being actuated, the spring biased actuating means causes the movable wall of the chamber to move outwardly thereof, opening valving between the reservoir and chamber and drawing an amount of matter to be applied or vaccine into the chamber. A measure or shot of matter to be applied is then held in the chamber until the valve between the chamber and needle is opened on axial movement of the proboscis relative to the needle.
