A steam-bath cubicle constructed from prefabricated wall and ceiling portions (3, 12), comprising plastic profiles with treated surface, has, on some of the wall portions (3), a resting part, for example a seat (8) or a bed or the like, which is formed in one piece with the wall portion. The portions are connected to one another and to an external wall and ceiling covering (9) with the aid of conn...

The invention concerns a procedure and arrangement for, in particular, the steering of circle-saw blades. The saw blade (1) is located in an electrical or magnetic force field, and an appliance (6, 7, 9, 10) is used to regulate the force field so that it tends to situate the saw blade in the desired movement path.

Several control rods are activated by a mechanism positioned on a rotor shaft, and normally inside it. For protection against fluid or pollutive matter, the mechanism is sealed. The mechanism can take the form of a Z-shaft, the inclined part of which is in contact with the rods. This achieves the angled configuration of the rotor blades.

Laminated steel alloy comprises (a) a high alloy steel and (b) a low alloy steel . Layer (a) consists of (wt.%) 1.0-2.5 C; 0.2-1.0 Si; 0.1-2.0 Mn; 4-18 Cr; 0.7-10 Mo; 0-1 Ni; 0.10 W and 0-10 (V + Ta/Nb+Ti+N), The toal amt. of Cr+Mo+W;V+Ta/Nb+tI+N is at least 12 wt.%, the remainder being Fe and inevitable impurities. Layer (b) consists of 0.3-0.7C; 0.2-1.0 Si; 0.1-2.0 Mn; 1-5Cr and from a trace up ...

The picture (10) has, in one or more limited parts, two or more superimposed transparent layers (3',11) with different fibre directions. For viewing the picture, components are placed on opposite sides of it to polarise light passing through it. - A relative rotation between at least one of these components and the picture is enacted, so that the viewed picture appears with varying colour composit...

The fluidising bed contains dispersed, calcined limestone, and the bio pulp is pyrolysed under the effect of reactor heat to form tar-mixed gas and charcoal. On flowing upwards in the reactor shaft, the tar is gasified in a heterogeneous catalytic reaction with the limestone and charcoal, and the stone is sepd. from the gas at the top of the shaft, being then fed back to the fluidising bed for com...

The lock (13a) sensor (2-4) monitors whether the safe box is provided with the unique marking when it is introduced into an insertion position, and if this be the case arrests the box, and releases a stop (4) which otherwise prevents locking by a key. The probing box arresting and stop release occur simultaneously. - The sensor has an arm (3) which is activated and moved when the box is placed in ...
