Patent DE-4203031-A1 (DE)
Inventor: SCHNEPP KATHRIN DR
IPC: C11D11/00
Filed: 1992-02-04
Abstract: The purpose is to produce solid washing and cleaning agents with a high powder density or a component therof by the addition of solid and liquid detergent raw materials with simultaneous or subsequent shaping and, if desired, drying, in which the agents containing the usual components like anionic tensides, builder substances, alkalising agents and liquid niotensides and, if required, water or aqueous solutions exhibit an improved rate of dissolution at temperatures between 15 and 60  DEG C. This is achieved in that firstly all the solid components are mixed together and then the liquid components are added. To improve the dissolving properties, an additive is introduced into the process after the solid components have been mixed. The additive to improve the dissolving properties consists of fatty alkyl sulphate, olefine sulphate, alkyl-aromatic sulphonates or mixtures thereof. The additive which is solid per se may be either introduced as the last solid component or added to the other already mixed solid components, or it may be introduced into the process in the form of an aqueous mixture, preferably in a 25 to 60 wt % aqueous solution. The per se solid additive content of the agent is preferably 0.5 to 8 wt %.

Title: Drag blades for hermetic pump running wheel - receive delivery flow fed by attached, driven hollow shaft producing torsion, and have entry angle of 90 degrees
Inventor: MAYER HELMUT DIPL ING
IPC: F04D29/18
Filed: 1992-02-06
Abstract: The blade (1) has an entry angle of Beta 1 = 90 deg. for the torsion produced by the connected hollow shaft (2). With reduced torsion through the hollow shaft, the medium rotates at the entry edge inevitably at its peripheral speed, and therefore with the greatest possible torsion. The blade is then performing as a drag blade, with thrust-free entry. The outlet angle (Beta 2), with normal blade curvature, is greater than that with known rearwards curved blades. ADVANTAGE - A new blade geometry for use on the running wheels of hermetic pumps.

Abstract: The invention relates to a pair of breaking tongs with tong jaws, the outside end sections of which have, in each case, at least one projection pointing towards the opposite tong jaw, the tong jaws being equipped in each case with a nipping region and a cutting region arranged downstream of the latter which adjoin the said extension. The said cutting region is formed by a shearing blade which is supported on a carrying surface of the tong jaw, which acts in the direction of the closing movement of the tongs and is attached to the tong jaw by means of clamping elements so as to be releasable transversely to the closing movement. To improve the economy and operating reliability of such breaking tongs, the shearing blades (7, 8) have a composite structure in the longitudinal direction and are held on the tong jaws (1, 2) via holding-up devices (14) in addition. The latter are opposed to the carrier surfaces (13) and are designed in such a way that resistance forces arising at the shearing blades during the opening movement of the tongs are absorbed. <IMAGE>
