Title: Railway traction vehicle
IPC: B61F3/04
Filed: 1979-05-24
Abstract: In a high speed railway traction vehicle, a motor-gear unit assembly (6, 10) is suspended directly from the vehicle frame (13) by three swing arms (7,8,9). Two swing arms (8,9) are connected together with each other by means of a torsion bar (23) in such a manner as to allow only movement of the motor-gear unit assembly (6,10) which is transverse to the direction of travel, whereas the third swing arm (7) is mobile on all sides. At high speed travel on a straight rail (1) a rigid connection is made between the motor- gear unit assembly (6,10) and the vehicle frame (13) by way of a first transverse tie rod (12) with a lockable coupling element (21). At low speeds and on a curved rail (1), the coupling element (21) of the first tie rod (12) is released and simultaneously a second coupling element (22) in a second tie rod (14) is locked, so that a rigid connection between the motor-gear unit assembly (6,10) and the bogie frame (4) is made. Power is transmitted from the gear unit (10) to the drive wheels (2) by way of a hollow Cardan shaft (18) and universal couplings. <IMAGE>

Title: Water Storage Tank
IPC: F24H1/18
Filed: 1979-09-27
Abstract: The polyurethane foam heat insulation (12) of a horizontally disposed cylindrical water storage, tank (10) for a solar water heater is thicker at the upper regions (14) than at the lower regions (16). This provides optional insulation where the residual hot water lies after some hot water has been drawn off and replaced by cold water at the bottom of the tank.
