An animal ear tag applicator tool which includes spaced apart first and second retention members each of which is adapted to retain an animal ear tag part. The tool has a body to which is pivotally attached a lever. Movement of the lever toward handle of body results in rectilinear movement of the first retention member toward the second retention member. The tool is characterized by a linkage which transforms pivotal movement of the lever into a varying speed rectilinear movement of the first retention member toward the second retention member relative to the movement of the lever itself.

Applicator tool

There is disclosed a valve unit for a liquid flow sensing device of the type having a control means which is movable between first and second positions when the flow rate is respectively low and high but biased to the first position. The valve unit comprises three valve sections one of which is movable in response to movement of the control means a second of which is fixed relative to the control means and a third which is movable independently of the other two sections. The valve includes first and second ports, port connecting means, a flow passage and a diaphragm which forms part of the chamber and can close said flow passage. The third valve section can be moved so that the first port is isolated from the second port but coupled to the chamber when the control means is in the first position and moves to the second position. Means are provided for coupling the third valve section to the first valve section such that when the control means reverts to the first position it moves both the first and third sections relative to the second section such that the first port becomes coupled to the second port by the port connecting means and the first port is isolated from the chamber. There is also disclosed a liquid flow sensing device incorporating the valve unit.

Liquid flow sensing devices

An applicator, for animal ear tags, of the type having two lever members pivoted together. The levers are formed on one side of the pivot point as handles. A body is mounted to one lever at the other side of the pivot and has a pin which normally projects therefrom. Apparatus is provided to retain a female component of an ear tag opposite the pin and this forms part of the aforementioned one lever. Within the body there is an apparatus to retract the pin from within the stem of a male component of an ear tag immediately upon the male and female components being coupled together following movement of the pin towards the retention apparatus.

Animal ear tag applicator

A liquid flow sensing device which comprises a weight sensitive control means movable between first and second positions though biassed towards the first position. A first valve section is provided which is movable in response to movement of the control means while a second valve section is fixed in relation to the first section. First and second ports are provided with either of the first and second sections and a third valve section is located in a cooperating relationship with said first and second sections. The third valve section has means for providing communication between the first and second ports and is movable independently of the first and second sections so that the first and second ports are isolated when the control means is in said first position and moves to the second position. Means are provided for coupling said first and third valve sections whereby as the control means reverts to the first position the first and second ports are connected.
