Abstract: A convector for heating buildings consisting of horizontal convector modules spaced a distance apart, one above the other. Each convector module has heat-conducting tubes, onto which are forced lamella bodies, the side lugs of said lamella bodies being bent in such manner that they are parallel with the tubes. At the front and back of each convector module is attached a cover plate which is bent around the upper and lower edges of the bent side lugs. Preferably, the lamella body in its unbent position is of H-form. A tool for manufacturing the convector modules has a movable cam member for picking up and advancing the lamella bodies and rollers for bending the side lugs.

Abstract: A power transmitting mechanism for reciprocating engines or pumps connecting the piston rods of a plurality of cylinders with a slant on a main shaft, the cylinder axes being parallel with the main shaft. The connection is provided by means of claw-shaped crossheads gripping the slant, one crosshead for each piston rod. Between the crosshead and the slant a main thrust block and a back thrust block are placed eccentrically. The crosshead may pivot around its longitudinal axis and is provided with two thrust blocks of the Michell type, the centres of these two blocks being arranged in a plane perpendicular to the longitudinal axis of the crosshead and in the middle of the gap of the crosshead.
