The convective pipes are open and are in communication with the atmosphere. The top part of the housing provided with the front wall is projected over the furnace door. The furnace together with the top zone forms a common space in the furnace chamber. The convective pipes which shield the furnace chamber are tightly secured to the lid along the front and back walls and in the bottom of the projecting top part of the housing and in its bottom, respectively. The convective pipes have open faces and are in communication with the ambient air. The inclined parts of the crossing convective pipes are provided with bottom and top gas directing shields which form with them the bottom and the top gas ducts, respectively. The top gas-directing shields are interconnected to form a dihedral angle. The pipes for supplying the secondary air are mounted upstream of the inlet to the bottom gas ducts, are bent toward the air flow in the shielding convective pipes, and are secured to them.

Abstract: FIELD: radio engineering, possible use in radio location and navigation systems. 
     SUBSTANCE: in the method for measuring absolute transmission time of short radio waves in ionosphere by means of radio signals with linear-frequency modulation, mode structure of ionosphere short-wave channel is determined and alignment of time scales of distributed stations is performed by signals of precise time with precision up to several milliseconds, probing of ionosphere is performed in whole linear-frequency modulation range of radio complex (3-30 MHz). In accordance to synchronized program, transfer to emission/receipt mode is performed at sliding frequency with speed 100 kHz/s in more narrow range of frequencies from f n  to f k =f n +100KHz, i.e., "saw" mode is realized with repetition period ΔT=1s. It can be called a synchronization mode. Frequency f n  lies within range of passage frequencies and may be changes in accordance to synchronized program in process of measurements. In time moment t 0  transmitter starts, receiver at other end of radio lines starts in time moment t 0 +Δt dis,  where Δt dis  - time of discrepancy of time scales of aforementioned transmitter and receiver. Differential frequency for receiver will be proportional: F 2 =(df/dt)Δt meas , where Δt meas =t gr -Δt dis , where t gr  - time of group transmission from transmitter to receiver; Δt meas =t gr -Δt s =0 and t gr = Δt s . Correction is performed during several emission cycles, during which measuring of differential frequency is performed and correction of Δt dis  is performed to provide F 2 =0. At next stage in time moment t 0 +Δt s =t 0 +t gr  transmitter launches. Supposing routes to be reversible, in time t gr  radio signal is received by receiver. Its differential frequency F 1  equals F 1 =2t gr (df/dt), and time of group transmission is determined as t gr +F 1 /2(df/dt).
