Title: Joining two metal pipes with the same dimensions - where one pipe is chamfered and pushed inside the other pipe
Inventor: COLAS FRANCOIS
IPC: B21D39/04
Filed: 1976-07-01
Abstract: Two pipes, esp. metal pipes, are joined together, where the pipes have the same dimensions and the walls are thin as compared with the pipe dia. At least the end of one pipe is chamfered, and then puchsed into the end of the other pipe, which is supported on its outside for a length at least equal to the depth of penetration of pipe into pipe; This prevents radial bulging of pipe. The outer end of pipe is pref. chamfered 5-20 degrees, and pipe (2) is provided with a conical bore of the same angle, before pressing pipe (1) into pipe (2); ring grooves are pref. also provided on the periphery of pipe (1) where a joint surface will be formed between the two pipes. A rapid and inexpensive method of joining two pipes with the same dimensions to form a strong-gas-tight joint without increasing the outside dia. of the pipes. The process can be used for joining gas pipes made of Al, z, Cu, S, or alloys based on these metals.

Title: Train speed control system - has limiting device and logic circuit which prevent acceleration to exceed determined value
Inventor: UEBEL HELMUT
IPC: B60L15/20
Filed: 1976-11-05
Abstract: The train speed control system modifies the speed of the train by selecting the value of the nominal speed or the value of the nominal acceleration. The system has limiting device and a logic circuit which connect the speed and acceleration values transmitted to the trains control unit. The limiting logic system ensure that modification to acceleration does not exceed a determined value. The nominal speed value used to modify the trains speed satisfies the equation Vs = square root 2.a.s. where 'a' is the acceleration or the braking deceleration; 's' the distance of braking or acceleration; 'Vs' the value of nominal speed. The logic circuit determines a value of corrected nominal speed. This connected speed in association with the limiting means gives to the train, during acceleration or constant deceleration, a speed which satisfies approximately the equation V = square root 2.a.s.

Title: Vortex cooling towers for power stations - incorporating vanes inducing rotational flow and convergent-divergent establishing vortex, giving greater efficiency with smaller towers
IPC: F28C1/00
Filed: 1976-12-09
Abstract: A conventional or nuclear power station incorporates wet or dry natural draught cooling towers in which the cooling air is put into rotation to form a vortex. The system for transferring heat from the power station cold source to the cooling air is at the base and the periphery of the tower. It comprises a system of vanes to put the air into rotation and a convergent-divergent to establish the vortex. The flow of air is controlled by introducing it at the base of the vortex by piping and valves, which can be fitted with an energy recovery system. Compared with standard installations, the efficiency of transfer of heat from the cold source to the ambient is increased, the dimensions of the towers are reduced, facilitating their insertion into the environment and energy is recovered.
