Abstract: A fuel distributor bar for petrol is closed at the end by a stopper, wherein the stopper is inserted into the fuel distributor bar and is soldered thereto. The stopper and the fuel distributor bar are designed for an operating pressure of 200 to 800 bars. A pipe wall of the fuel distributor bar is provided with a return internally at the end for said purpose. The stopper is in engagement with the return and has a projection that terminates flush with the pipe wall of the fuel distributor bar.

Abstract: The hybrid housing includes a base housing and one or more separately made functional components joined in the base housing by electron beam welding to provide a hermetically sealed hybrid housing e.g. for use under water or in aircraft or spacecraft. The separately made functional components can included e.g. a KOVAR-glass feed-through device and/or a copper or molybdenum metal block for heat dissipation. The base housing can be made of aluminum, an aluminum alloy, stainless steel or VA steel.

Abstract: The disclosure relates to a process for making calciummonohydrogen phosphate dihydrate with a high degree of whiteness from pure phosphoric acid and naturally occurring calcium carbonates. More particularly, a fine-particulate calcium carbonate is suspended in water and the suspension is mixed at temperatures between 0.degree. and 60.degree. C. with phosphoric acid so as to establish a Ca/P-ratio of 0.20 up to 0.57. The phosphoric acid is added in quantities per unit time preventing the resulting mixture from foaming over. Next, solid matter constituents are separated from the mixture, after CO.sub.2 has ceased to evolve, with the resultant formation of a clear colorless acid solution. This solution and an aqueous suspension or solution of pure alkali metal and/or alkaline earth metal carbonates and/or hydroxides, are jointly introduced into a reaction zone at a reaction temperature of 20.degree. to 45.degree. C. so as to establish a pH-value initially of 2.0 to 5.
