Title: Counterbalanced pressure vessel lid - has steel cable passing over curved part of bearing block controlling open position of lid
Inventor: TRAUTMANN CHRISTIAN
IPC: E05F1/12
Filed: 1977-12-19
Abstract: The lid (1) for a boiler or similar vessel is secured by a hinge arm (4) mounted on a bearing block (8). Its weight is compensated by a spring (3) attached to the block (8) by a non-expanding flexible tensile connection such as a steel cable (5). This adjoins a curved part (6) corresponding to the torque line of the lid. The shape of the curve enables the spring path to be altered to suit the torsional force so that the characteristic line of the spring force always agrees with that of the torsional force of the lid. Thus the lid can be fixed at any hinge position, and the steel cable is wound up or unwound from the curved part. The free cable end then becomes nearer to or further from the spring so that the spring becomes taut or relaxed and the actual weight of the lid is balanced.

Title: Conveyor in tunnel kiln for baking ceramic prods. - which rest on trays travelling on two longitudinal rows of balls located in grooves in baseplate
Inventor: BUSCHERMOEHLE GREGOR
IPC: F27B9/26
Filed: 1978-07-19
Abstract: The conveyor consists of a longitudinal row of baseplates possessing a longitudinal groove near each longitudinal edge of the baseplate; and in each groove in a row of balls carrying slides or trays on which the ceramic workpieces are placed. The slides or trays roll on the balls so the workpieces are conveyed through the furnace. On the baseplates, and between the two grooves, is a longitudinal row of holding-down plates employed to prevent the balls from moving upwards out of the two grooves. Each plate has two longitudinal edges which are curved to march the contour of the balls. A similar conveyor is described in DT2220392, but the balls are never completely round and exactly the same size so they tend to rise out of the grooves. The present invention eliminates this problem.
