Patent ES-426731-A1 (ES)
Title: Automatic connecting valves for reserve pumps
IPC: B62D5/30
Filed: 1974-05-29
Abstract: In systems using a main pump and a reserve pump where it is essential that pressure feed to a consumer unit, e.g., a vehicle booster steering device, be available in the event of failure of the main pump, the invention provides quick shifting to a reserve pump. The effect is achieved in two embodiments of the invention by means of a valve which is spring biased to a closed flow condition of the main stream from a main pump, but opening the main flow responsive to consumer unit demand, while, however, permitting continuous reserve pump flow to reach the consumer unit prior to such opening. A pilot stream from the main pump establishes a pressure differential on the valve to control response to main pump failure for cutting in the reserve pump. The pilot flow is through a pressure chamber means in which a drop in pressure due either to unit demand or main pump failure is effective to cause valve actuation for main flow opening, or valve opening for reserve pump flow. An important feature of the invention resides in the fact that the pressure drop is achieved either by loss of main pump pressure or reduction in discharge rate, e.g., due to a slipping drive belt of the main pump.

Title: Products forged in aluminum alloys with improved mechanical characteristics and a method for obtaining same
IPC: C22F1/053
Filed: 1975-01-03
Abstract: The invention relates to products forged in aluminum based alloys with a very low hydrogen content.

Title: Butt welding large tubes manually - using initial pass without feed metal and second pass with internal depression
IPC: F16L13/02
Filed: 1979-12-11
Abstract: The ends of two tubes are joined together by welding by rigidly (a) fixing the tubes end to end in contact, (b) making a first welding pass without feed metal, (c) creating a depression inside the litres esp. surrounding the joint, and (d) effecting a second welding pass while maintaining the depression. At least are further welding pass is effected using feed metal without the internal depression. The method is used in large tube manual welding esp. in the nuclear field. The internal depression prevents the formation of an uneven internal weld surface, ensuring formation of an inwardly curving meniscus. This ensures a sound weld suitable for preventing leakage of radioactive material passing over the joint through the tubes.
