Title: Rectangular section tunnelling shield - has horizontal partitions advanced by pistons to make different depths of cut
IPC: E21D9/06
Filed: 1975-12-29
Abstract: The tunnelling shield of square or rectangular outline for forming correspondingly shaped tunnels, has two or more partitions mounted horizontally across its interior. Thus the excavated soil is deposited on them in layers instead of forming one deep layer. This assists the operation greatly especially when the front face of the machine slopes forward. In another design, each partition is formed by a fixed portion (32, 33) and a sliding portion (34, 35) which is pushed forward by a piston (39, 40) to make cuts of different depths. This prevents collapse of material from above due to excessive pressure. An automatic control system can be used to maintain the correct pressure against the sliding portions.

Title: Blast furnace gas pressure control - by gas turbine shunting gate valve and controlled by load speed setting units
Inventor: INUBISHI MASANOBU
IPC: C21B7/00
Filed: 1976-02-13
Abstract: The blast furnace gas pressure control can be switched over in case of necessity partly or fully from the conventional gate valve to a gas turbine which lies in a shunt circuit to the latter. A pressure setting device supplies a high setting and a slightly lower setting. The load setter can be used to vary the load on the turbine. The switch from one type of control to the other is effected automatically by the load setter as a function of the changing turbine load. This avoids the throttling losses caused by using only a gate valve for the pressure control. The new system can absorb irregular and sudden fluctuations in the rate of blast furnace gas produced.

Patent FR-2356893-A1 (FR)
Inventor: CARRA GIANNI
IPC: F26B3/04
Filed: 1977-06-23
Abstract: The chamber of the dryer at higher temperature, that is to say (12), is heated indirectly by means of heat exchangers (7) which are traversed by the hot gas (F1) which is discharged successively to the outside. From the chamber (12), a flow of humid hot air (S) is taken, which affects methodically the heat exchangers (21) and (26), respectively outside and inside the chamber (11), the opening (31a), the space (29), to be conveyed back finally into the chamber (12). The flow (S) is cooled to the saturation of the steam which it contains in the exchanger (21) and loses, by condensation, some water in traversing the exchangers (26); said water is discharged to the outside by means of ducts (28). The heat, taken from the flow (F1), which is necessary to make a given quantity of water evaporate from the bricks situated in the chamber (12), is recovered and given up by the flow (S) to the chamber (11), neglecting the dispersions to the outside and the part lost in the exchanger (21).
