Abstract

943,398. Unit apparatus. FIRTH CLEVELAND Ltd. Nov. 16, 1959 [Nov. 17, 1958; April 15, 1959; April 27, 1959], No. 28481/63. Divided out of 942,537. Heading F4V. [Also in Division F1] A cross-flow fan has two rotors 209, 210 driven by a motor 207 which is rigidly secured to guide walls 201, 202 forming an outlet in which is incorporated an electrical heater 230 which is arranged to provide greater heating opposite the rotors than opposite the motor. For cooling the motor baffles 235, 236 may be arranged as shown in Fig. 3. Specification 876,611 also is referred to.
