Title: Alkali aluminosilicates used as builders in detergent compsns - treated with pentasodium triphosphate to improve wettability
Inventor: REOBKE WOLFGANG DIPL CHEM DR
IPC: C11D3/00
Filed: 1975-03-12
Abstract: Surface of ion-exchanging, crystalline alkali aluminosilicates used as builders in washing, cleaning or rinsing compsns. is rendered hydrophilic by mixing the alkali aluminosilicate with up to 30 wt. % of Na5P3O10, Drying and grinding. Na5P3O10 can be introduced in the form of an aq. soln. Suitable alkali aluminosilicates are zeolites of the A, X and Y types; the alkali can be Na, K or Li. Alkali aluminosilicates are capable of exchanging the alkali ions for Ca2+ and Mg2+ thus exerting a water-softening effect. They can be used for this purpose in washing, cleaning or rinsing compsns. instead of the objectionable phosphates, under the conditions that their wettability is improved by a surface treatment such as described above (otherwise their action is too slow, esp. for use in washing machines, and they tend to form encrustations on the walls of the washing vessel at the air-liquid boundary.).

Title: Two stage reaction type steam turbine - has separate steam inlet headers with separately controlled flows to give even loading
Inventor: NISHIJIMA SHOJI DIPL ING
IPC: F01D9/00
Filed: 1976-08-10
Abstract: The turbine has a rotor (1) carrying two sets of reaction blading (8, 9). Flow is from the centre outwards and the inlet header spaces (4, 5) in the stator are separated by a central partition (3) which has a labyrinth seal (6) to the shaft. Steam is admitted to these two headers from a common header (10) surrounding them and the flow from the common header to the individual headers is controlled by separate valves (11, 12) for each individual header. Turbine output is controlled by varying the flow through these valves. The interposition of the individual headers between the main header and the blades ensures that a reduced steam flow is evenly distributed over all blades. This eliminates uneven loading and so reduces the stresses in the blades.
