Abstract: 1,110,849. Agitating liquids. ALFA-LAVAL AKTIEBOLAG. 3 June, 1966 [4 June, 1965], No. 24776/66. Heading B1C. [Also in Division F4] Air immersion cooler, suitable for cooling, mixing and agitating a liquid 16, comprises a sleeve-like cooling body 14 in the bore of which is arranged a pump rotor 15 coupled by a flexible connection to an electric motor 10. The connection may for example comprise a flexible connection between a rigid shaft and the motor or, as shown, a flexible shaft 12 connecting the rotor and the motor. The cooling body 14 is at least partly immersed in the liquid and supplied with a compressed coolant which, during use of the apparatus, evaporates inside the body. To prevent wobbling of the shaft, particularly when the motor is switched on and off, the rotor is made in one piece with a damping body 13. With the rotor activated liquid is caused to flow upwardly between members 13 and 14 as a result of which a circulation is set up which exerts a radical and centralizing force on the damping body and so counteracts any tendencies of the shaft to wobble. The damping body 13 is preferably hollow and made of synthetic plastic material or filled with foam rubber or plastic, and the sleeve like body is attached to the motor so forming a movable unit.

This consists of a rectangular box and a series of internal conductors which extend from one side, or alternately from opposite sides, of the box and form a series of coupled resonant circuits. As shown, a block B of polystyrene coated with silver forms the box and coatings H2-H6 on the walls of holes extending through the block form the internal conductors. In a modification (Fig. 5, not shown), the major part of each internal conductor is formed by a rod which is located in one of the holes and makes contact with a short length of conductive coating at one end of the hole. The internal conductors may be tuned by conductive screws R (one only shown) carrying rods which extend into the coated part of the tubes. The end conductive coatings may be connected to the internal conductors of coaxial sockets P (one only shown).
