A frame profile (1) and a bar profile (2) are connected to one another via T-connectors (3 and 4) fastened on the frame profile (1). For mechanical connection, use is made of bolts (9 and 10) which pass through the bar profile (2) and engage into receiving ducts (7 and 8) of the T-connectors (3 and 4). In the respective joint region, the T-connectors (3 and 4) are provided with adhesive-distributi...

A frame profile (1) and a bar profile (2) are connected to one another via two T-connectors (4 and 7) which are fixed on the frame profile (1). Resulting in the joint region is a gap which, according to the invention, is sealed by a sealing cushion (13) fixed on the frame profile (1). The sealing cushion (13) consists of an elastic material, preferably of closed-cell foam. The thickness of the sea...

Process for the preparation of aqueous nicotinaldehyde A process for the preparation of an aqueous medium of nicotinaldehyde by the catalytic reduction of 3-cyanopyridine under hydrogen in the presence of Raney-nickel.

A frame profile (1) and a ladder profile (2) are connected to each other by T-connectors (3 and 4) that are secured to the frame profile (1). Bolts (9 and 10) that pass through the frame profile (2) and fit into receiver channels (7 and 8) in the T-connectors (3 and 4) serve to connect these parts mechanically. Within the particular junction or joint area, the T-connectors (3 and 4) incorporate ad...

A frame profile (1) and a ladder profile (2) are connected to each other by two T-connectors (4 and 7) that are secured to the frame profile (1). Within the butt area there is a gap which, according to the present invention, is sealed by means of a sealing pad (13) that is secured to the frame profile (1). The sealing pad (13) consists of an elastic material, preferably of a closed-cell foam. The ...
