The invention relates to a method for preventing safety cell penetration by a laser tool (7), which laser tool (7) is manipulated by a serial manipulator (2) and enclosed by a safety cell (9, 10), which method comprises the steps of: reading the orientation of each joint (3-6) of the serial manipulator (2), calculating the position and orientation of the laser tool (7) using the read orientations of the joints (3-6) and the geometry of the serial manipulator (2), calculating the intersection point of the laser beam (14) axis of the laser tool (7) with a wall of the safety cell (9, 10),calculating the heat input of the laser beam (14) at the intersection point (15), shutting down the laser beam (14) of the laser tool (7) when the calculated heat input rises above a preset threshold. The invention relates also to a combination of a serial manipulator (2), a laser tool (7) a CNC controller (11), a safety cell 89, 10) and a prevention device.(16).

The invention relates to a transport means for displacing an object with a bottom frame with a rectangular bottom footprint over a ground surface, which bottom frame is provided close to each of the corners with a support such as for instance a castor or a swivel wheel, such as for instance a rolling container, which transport means comprises: - a frame provided with frame wheels for displacing the transport means over and parallel to the ground surface in a main direction of travel; - a first lifting device for lifting a first object, wherein the transport device also comprises a second lifting device for lifting a second object, which first and second lifting device are arranged on the frame and are each displaceable independently between a rest position and a lifting position, wherein the lifting devices are each configured to be in contact with the bottom frame of an object positioned thereabove in the lifting position, and to lie clear thereof in the rest position.

The invention relates to an adapter (10)for a balcony drain, which balcony drain has a housing with an inlet opening and an outlet opening, wherein a grating is arranged in the inlet opening, wherein provided in the grating is an insertion opening for a standpipe for coupling to a balcony drain of a higher-lying balcony,wherein the adapter (10) comprises:- a tubular housing (11) having at a first end a connecting piece for connection to a standpipe and wherein the cross-section of the other end corresponds with the insertion opening of a balcony drain, such that the other end of the tubular housing can be inserted into the insertion opening, and wherein inflow openings (14) are provided in the wall of the tubular housing;- a funnel (16, 17) arranged in the tubular part, wherein the funnel-like part lies with the upper edge against the inner wall of the tubular housing between the first end and the inflow openings and wherein the outflow of the neck of the funnel extends beyond the inflow openings in the wall of the tubular housing.

The invention relates to a method for obtaining geological information of a soil sample, which method comprises the steps of:- providing a soil sampling tube having a tip portion, a top portion positioned opposite the tip portion and along the length, between the tip portion and the top portion, a cutaway portion extending along a substantial part of the length of the tube;- inserting the soil sampling tube into the ground to a predefined depth, while registering the insertion force in combination with the insertion depth of the tip portion;- while retracting the soil sampling tube with a soil sample out of the ground, analyzing the elements in the soil sample at discrete positions starting adjacent to the top portion end and moving towards the tip portion end of the soil sample tube;- combining the analyzing results per discrete position starting adjacent to the top portion end and moving towards the tip portion end with the registered insertion force for the insertion depth of the tip portion starting from the insertion to the predefined depth.
