Filed: 1961-09-29
Abstract: 964,999. Thermal partly magnetic switches; protective arrangements. SIEMENS & HALSKE A.G. Sept. 29, 1961 [Sept. 30, 1960], No. 35275/61. Headings H2B and H2H. A telephone line FL is connected to earth through a thermo -magnetic relay R and a spark gap voltage arrestor FS. On overload the relay causes contact set r1 to close, short-circuiting the relay and the spark gap, and contact set r2 to close, sounding an alarm bell W. The relay comprises a permanent magnet Da which maintains a balanced armature A<SP>1</SP> in engagement with pole shoes P3, P4. These pole shoes are formed as serially connected non-inductive windings St, St<SP>1</SP> which are made of a substance whose permeability decreases with increasing temperature. On overload, current flows through the windings St, St<SP>1</SP>, causing a decrease in their permeability and allowing contact set r to close under the action of a spring. The relay is maintained in the operated position by the flux flowing through the polepieces P1, P2 and the armature. A relay having an unbalanced armature co-operating with one pole shoe which is in the form of a thermo-magnetic non-inductive winding is described, Fig. 2 (not shown).

Abstract: Organic polyether polyisocyanato polybiurets of the general formula <FORM:1033913/C3/1> where R is an organic radical obtained by removing the -NCO groups from an organic diisocyanate, R1 is the radical obtained by removing the -NH2 groups from an o , o 1-diamino polyether and X is a hydrogen atom or an -CO-NX-R-NCO radical, with the proviso that at least two X's are not hydrogen atoms in the molecule.  The o , o 1 diamino polyethers may be prepared by the process of Specification 1,033,912, by reacting a polyhydric polypropylene ether with ammonia in the presence of a hydrogen transferring catalyst, e.g. Raney nickel, Raney cobalt, nickel, fuller's earth, Ni or Co supported on molecular sieves, SiO2 gel, Pd, Pt or copper chromite.  The ammonia may be mixed with amines.  Other polyethers which may be converted by the above process are (1) tetrahydrofuran polymers, the primary OH groups of which have been converted to secondary OH groups by reaction with propylene oxide, (2) polythioethers of thiodiglycol or of thiodiglycol and other polyfunctional alcohols, (3) addition products of ethylene oxide, propylene oxide or their sulphur analogues and polyfunctional alcohols, (4) addition products of ethylene oxide or propylene oxide and their sulphur analogues and polyhydric phenols or aromatic polyamines.  The polybiuret may be derived from linear o , o 1 diamino polyethers by reaction with at least 3 moles of an aromatic or aliphatic diisocyanate which may contain up to 50% of triisocyanates in the presence of an inert organic solvent. The polybiuret may be reacted with a polyether, polyester, polyesteramide or polyacetal to form a cellular or homogeneous polyurethane.  Water or a blowing agent together with a surfactant may be included in the reaction mixture. Conventional tertiary amine and tin and other metal containing catalysts may also be included. The polyurethane forming reaction may be effected in an organic solvent.  A chain-extender or cross-linking agent may be used in a second step.  In Example (1) a biuret polyisocyanate was prepared by reacting hexamethylene diisocyanate with a mixture of polypropylene glycols containing mainly o , o 1-diamino propylene glycol polyether.  In Example (12) the polybiuret reaction product of Example (1) was reacted with a polyethylene glycol adipate polyester in the presence of dibutylin dilaurate.ALSO:In example 12 a viscous reaction mixture containing polyethylene adipate polyester, a biuret polyisocyanate obtained by reacting hexamethylene diisocyanate with a mixture of W, W1 diamino propylene glycol polyethers, and dibutyltin dilaurate, was cast in thin layers on to a fabric of either cotton, polyacrylonitrite or terephthalic acid-ethylene glycol-polyester.  The coating was heated for 24 hours at 100 DEG C. to obtain a cross-linked polyurethane.
