Abstract: A closing device for curtain compartments (2, 3), suspended below a glass roof, with fastened rear edges. The front edges of the compartments can be drawn by means of a leader (20) of a row of draw cords (12), arranged in parallel, along a fixed path for the tight engagement with the rear edge of a curtain compartment arranged ahead of it in the drawing direction. Rear-edge supports (25) which are tensioned at the rear lug of each curtain compartment (2) are suspended on a support cord (24), extending transversely to the draw cords, by means of a bar (30) which extends around the leader (20). Two draw parts (18, 19) are mounted firmly on the leader (20). The front draw part (18) is arranged in such a way that it can press the bar towards the rear, i.e. in the drawing direction, when the curtains are almost drawn. As a result, the rear-edge support tilts upwards against the front lug (34) of each curtain compartment (3), said lug now turning towards it, for mutual sealing of the two curtain compartments. When the curtain compartments are drawn away, the rear draw part (19) strikes against the bar (30) and thus tilts the rear-edge support forwards so that the folds (35) of the curtain compartments are pressed against the rear-edge support which is tilted forwards. As a result, it is ensured in a simple manner that the folds, seen in the longitudinal direction of the roof, take up the smallest possible space and thus cause the least degree of shade.   <IMAGE>

Abstract: The method comprises producing a plug (3) of earth facing outwards the water, along which is formed a connection, the bottom surface of which is approx. at the same level as the base of the tunnel. A concrete block (4) is then cast, and once it has hardened, the plug is is removed. - A new plug is then cast further into the tunnel to form an outer chamber between it and the concrete block. In this chamber, connecting work can take place in dry conditions, and the block can then be placed under water so that the pipe line can be moved freely through a hole (5) in the block. So as to protect the concrete block when the plug is removed, a buffer or cushion (8) can be positioned against the exterior of the plug.

Abstract: The present invention provides an apparatus and method for measuring the hardness of a metal object such as a railway wheel. The wheel is rolled along a rail to a notched receiving assembly into which the wheel is lowered to stabilize the wheel in a longitudinal direction. A frame with a bracing device is then pressed against the wheel hub to stabilize the wheel in a lateral direction. A secondary frame including both a grinding device and a hardness testing device is then swung about a pivot axis such that the grinding device grinds a section of the metal railway wheel. Upon the continuation of the pivoting movement of the secondary frame, a hardness testing device is brought into alignment with the ground section of the railway wheel whereupon the hardness test of the wheel is performed.

Abstract: A locking device in safety belts for a tongue comprises a locking member (10) adapted to be rotated around an axis (b) between a release position and a locking position. The locking device also comprises a latch member (29) for the locking member and a movable operating member (30) to release the tongue. The locking member (10) has a contact surface for the tongue (19), the perpendicular (N) of which in the locking position of the locking member passes through a torque axis (A) which is parallel with the axis of rotation (B) of the locking member and which is so positioned that a force on the tongue (19) in the direction (U) of withdrawal of the tongue causes a resultant torque (M) on the locking member towards the release position of the locking member, so that it is easier to release the tongue when the safety belt is loaded. The axis of rotation (B) of the locking member is positioned outside the contact surface of the locking member, as seen in the direction (U) of withdrawal of the tongue. The locking member may be mounted on a resilient lug (27) yielding when the safety belt is very heavily loaded, as for example in a collision, so that the locking member then is self-locking.

Abstract: A method for the removal of a screw motor (1) with screw thread-shaped lobes (29) from a mould (2) comprises axial displacement of a removal element (5) provided with threads (6) that cooperate with threads (7) on a control element (8), the two sets of threads being coaxial with the rotor and of the same height as the lobes. The axial movement of these threads towards the removal element causes it to rotate relative to the control element. The removal method comprises: (i) moving the control element in a first axial direction until one of its surfaces (23) comes into contact with a surface (22) on the rotor, this relative movement between the removal and control elements ensuring that their threads come into contact with each other, forcing the control element to be pulled in a second axial direction; (ii) locking the control element into position to prevent any axial movement; and (iii) moving the removal element in the first axial direction until the rotor has been removed. The device for carrying out this removal method is also claimed, comprising a locking body (19) for preventing axial movement of the control element, a first drive device (12) for moving the removal element, and a second drive device (24) for moving the control element.
