Patent DE-4202240-A1 (DE)
Inventor: HAUSCH GERNOT DR
IPC: H01F3/00
Filed: 1992-01-28
Abstract: In order to produce a pulse generator, in the case of which a voltage pulse, which is independent of the magnetic field change, can be produced by sudden reversal of the magnetisation (Barkhausen effect) when a magnetic field is applied, an iron alloy 2 is used for one of the materials of the composite body, the additional alloying components of which alloy are selected such that a structural transformation takes place, with a volume change, at different temperatures in each case. In order to produce the braced state, heat treatment is then carried out, which includes heating above the upper transition temperature and cooling below the lower transition temperature. This results in considerably higher stresses between the materials of the composite body and hence a pulse behaviour which is considerably better than that known and which can be used for identifying constant or alternating magnetic fields. <IMAGE>

Abstract: Claimed is the application of complementary peptides in oncology and cardiology. Potentially (i) a substance VPH (NH2 - Leu alpha N-Me-Phe Tyr Lys AlphaN-Me-Lys Val D-Tyr-COOH is anti-neoplastic; (ii) variation of the prim. structure of the peptide mimetic of calcium (Dillon, J. et al, Proc. Natl. Acad. Sci USA 88, 9726-9729) is an agent for hypertension or for tumours by inactivating the multi drug resistance gene prod.; (iii) peptide hSNI(B16-21) (3'-5', NH2 - Leu-Pro-Thr-His-Asp-Ala-COOH) is useful in diseases including tumours which occur together with insulin hyperproduction, and (iv) complementary proteins to insulin and insulin growth factors I and II are similar to the complementary peptides of oncoprotein E7 of the human papilloma virus type 16 and to the complementary peptides of the binding proteins binding to the retinoblastoma (RB) protein which regulates cell growth. Therefore, these proteins may be competitors for the RB-protein binding site, pref. binding RB protein 649-654. USE - The complementary peptides are administered to cancer patients as a potentially more potent anti-cancer agent which also shows fewer side effects than known agents. In the case of treatment of hypertension the suggested peptide mimetic of calcium could be an alternative to known calcium antagonists.

Patent DE-4304021-A1 (DE)
Title: Winch arrangement
Inventor: POSNER BURKHARD
IPC: B66D1/60
Filed: 1993-02-11
Abstract: The winch arrangement generally has a winch drum which can be rotated manually or by motor force in order to wind and unwind a rope which is led in front of the winch drum via a deflecting device. So that the rope is received on the rope drum in adjacent rope windings in such a way that the entire receiving space of the drum is filled virtually without gaps, the deflecting device consists of at least one fixed rod and at least one guide pulley arranged in a displaceable and rotatable manner on the rod and having a peripheral groove in which the rope is guided. During the winding of the rope, this guide pulley is automatically guided to and fro between lateral stops of the rod, which are essentially in alignment with the inner walls of the winch drum facing one another, so that a maximum rope length can be wound onto the winch drum. In a further development, the winch arrangement is transportable and contains a rigid supporting device, which can be placed against an upright tree and absorbs compression forces, and a pull chain which embraces the tree in the fastening position. The winch arrangement can be attached to a tree quickly and easily and is very well suited to the pulling of felled trees.
