Abstract: A training course for race horses or other animals has a guide (2) which extends along a preferably endless track (1) and follows the shape of the track. A plurality of mobile units or carriages are caused to travel along the guide by a motor in the lead carriage. Each unit or carriage includes a member (6) for tying the animal (5) to be trained thereto to make it move along the track without the help of a trainer. The exercise of the animal is controlled by monitoring its pulse rate.

Abstract: A heat-emitting radiator supplied with electrical energy and preferably capable of co-acting with two holding means in conjunction with a radiator-supporting means, such as a wall. The holding means associated with the radiator comprise a first rail preferably having current-conducting means, and a second rail. One or more cassettes being insertable between the rails. A connecting cassette without heat-emitting resistance device has a contact means for co-operating with the contact rail. Said connecting cassette is inserted in the first rail and the second rail, arranged to feed current to said contact rail. Each further cassette is held in the rails, feed by current applied to said contact rail.
