Title: Tube bank heat exchanger
Inventor: BECKER JOERGEN
IPC: F28D7/16
Filed: 1969-10-24
Abstract: This heat exchanger is used for heat transfer between fluids at different pressures and the fluid flowing through the tubes has a high inlet temperature. Thermal forces generated are diverted from expanding tubes into the heat exchanger shell through an additional end plate near inlet end. This end plate rests loosely on the step in the vessel wall and the tubes rest on this plate through their spider supports. This arrangement protects a relatively thin end plate from high thermal stresses.

Title: Automatic disc- and shoe brake adjustment unit - contains two sleeves with toothed edges, and a spring
Inventor: TURNER KENNETH RICHARD
IPC: F16D65/56
Filed: 1973-08-08
Abstract: The adjustment unit is esp. suitable for wedge actuated brakes, having a transmission element, which moves to and fro, to transmit the movement of an actuator onto a friction brake element.
