Title: Tunnel kiln - continuous feeding and conveying system, for ceramic or metallic articles heat treatment
Inventor: GARBE FRIEDRICH
IPC: F27D3/12
Filed: 1972-04-19
Abstract: A slide rail leads through the tunnel kiln, the track being of closed ellipsoidal form, and of steel with lateral guiding to take containers in which are loaded the objects to be fired. Conveying of the containers on the track is by a lateral horizontal electrically driven friction belt on pulleys located at the end of the unloading/loading section of the closed track beyond the kiln. On the side of the track opposite the friction belt are located reaction idler rollers, the individual containers passing between the belt adn the rollers, thereby pushing forward the preceeding containers on the track. The loading of the containers into the kiln is by a similar friction drive belt driven at a slightly lower speed than the conveying drive to ensure continuity in the line of shunted containers between the drive points, and thus a constant speed of progression of the containers through the kiln.

Title: Hot reducing gases prodn - for injection into blast furnaces by partial catalytic steam oxidation of hydrocarbons
Inventor: POOS ARTHUR
IPC: C01B3/38
Filed: 1974-01-21
Abstract: Hot reducing gases contg. mainly CO and H2, and intended for injection into blast furnaces, are prepd. by partial catalytic steam oxidn. followed by elimination of water and CO2 from the gases leaving the reformer by cooling and absorption, the reducing gases are heated by the enthaply of the fumes issuing from the reformer and are then brought to the final temp. required by means of a smaller heater in which the heat needed is supplied by a burner, the fumes originating is this small heater are introduced again into the cycle of the fumes issuing from the reformer. The injection of the hot reducing gases into the blast furnace reduces the coke consumption. Costly conventional heaters are not needed. Less equipment is needed for the prodn. of steam. The cost of the reducing gases is lowered. The use of the small heater avoids the need for burners to supply supplementary heat.

Title: Testing circuit for railway light signals - becomes operative independently when constant or flashing lights are switched on
Inventor: PETERSEN HANS
IPC: B61L5/18
Filed: 1974-01-22
Abstract: The testing circuit is used for detecting stray voltages in the railway light signals when these signals are switched on. When the continuous or flashing signal light is switched on then the associated testing circuit is made independent from the response of the switching elements in order to detect a flashing phase start for the flashing light signal. The testing circuits and the actuating circuits are used for two light signals which will operate, if required, with continuous or flashing lights. On operating the continuous light the testing process is initiated by closing an actuating contact. The defects in the flashing light signal circuit can be protected by using a circuit which synchronises the testing process with the start of a flashing phase.
