Patent DE-3940257-A1 (DE)
Inventor: POEPELT BERNHARD
IPC: H02K11/00
Filed: 1989-12-06
Abstract: 1. Housing box for a thermal protection switch. 2.1 It is known for thermal protection switches to be fitted in the encapsulated state in a thermally connected manner to the active part of electrical machines. This necessitates a corresponding assembly cost and, in addition, particularly thermal protection switches which operate as a function of current require a corresponding installation volume. The new housing box is intended to permit thermal protection switches to be fixed on the wound stator such that they can be removed and without being incorporated into the field winding. 2.2 The housing box (10) is dimensioned and shaped such that it can be accommodated in the intermediate space (25) between the winding head (26') of the field winding (26) of a salient pole stator and the stator laminate stack (28'), and can be fixed in its in-use position (Fig. 6). <IMAGE>

Title: Non-toxic herbicide based on aq. cyanamide solns. - also contains mono:amino-, di:amino- or tri:amino-guanidine salt as synergist
Inventor: YOUNGMAN RICHARD DR
IPC: A01N47/44
Filed: 1990-07-31
Abstract: A herbicide based on an aq. cyanamide soln. contains, as an additional component, a guanidine salt chosen from mono-amino, diamino or triaminoguanidines. The inorganic guanidine salt, esp. the nitrate is used. The concn. of active ingredients in the aq. soln. is 0.1-10 (esp. 0.5-5) wt.% and the wt. ratio cyanamide:aminoguanidine salt is 99:1 to 10:90. USE/ADVANTAGE - The mixt. of cyanamide and guanidine salt is synergistic, even though the guanidine salts themselves have practically no, or only a very weak herbicidal effect. Thus smaller amts. of cyanamide can be used. Both components are completely degraded in the soil and the mixt. can therefore be used as many times as necessary, within one vegetation period. The mixt. not only leaves no toxic residues, but also, on account of its high N-content is a valuable nutrient source for crops. The mixt. is an environmentally friendly herbicide.
