Abstract: The invention relates to a system for deterring aquatic animals. The system includes a plurality of deterrent modules which are spaced apart from, and interconnected with, each other, and which are, in use, positioned/located in a body of liquid at spaced apart positions/locations. The deterrent modules are configured to generate an electro-magnetic field(s) between the spaced apart deterrent modules such that, when the deterrent modules are located in the body of liquid, an electro-magnetic field(s) is generated between the deterrent modules within the body of liquid, to thereby form a non-physical barrier between the deterrent modules within the body of liquid, which deters aquatic animals. The system also includes a management module which is configured to monitor the operation or functioning of each deterrent module by receiving data from each deterrent module. The data received from each deterrent module relates to an operation or functioning of the particular deterrent module.

Abstract: A tool for the multicomponent injection molding of brush bodies and more particularly of toothbrush bodies, including two tool parts able to be moved towards and away from each other and which between them jointly define a plurality of mold cavities. In accordance with the invention at least two of the mold cavities are permanently associated with different components. The at least one mold cavity, which is permanently associated with the first component to be injected, has a recess in the shaping surface of the one tool part, such recess being able to be shut off by an insert element, which is able to be moved in relation to this tool part and on which a head is formed, which, when the mold cavity is shut off by the insert element, extends into the cavity. The insert element is mounted on a carrier such that a premolding molded in this mold cavity, which is associated with this component to be injected firstly, may be moved into another mold cavity associated with another component.
