A fluid magnetiser is constituted by a rotary element which has a magnetic field generation section, is rotatably mounted in a fluid passage or reservoir chamber and communicates with a rotation drive means.

An overcap assembly for a container having a pressure valve or the like, for dispensing a product selectively as a spray or a fog. The assembly has an overcap and a nozzle device which can be attached to the overcap outlet and is rotatable or otherwise movable between two positions relative to the overcap. In one position, a first outlet of the nozzle device communicates with the pressure valve of...

Erectile dysfunction, particularly impotence, priapism and Peyronie's disease is treated by the transurethral administration of a therapeutically effective agent. The agents are administered to the urethra by means of a penile insert (1) having a rapidly releasing coating (4) containing the agent on its exterior surface or by means of an inserter (27) carrying an agent containing dose of agent (31...
