KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die Warmhaltung mittels leicht schmelzender Salze nach einem bekannten Verfahren beruht darauf, daß die das warmzuhaltende Gefäß umhüllende Salzmischung, nachdem sie von der an das Gefäß von irgend einer Wärmequelle abgegebenen Wärme geschmolzen war und durch diesen Vorgang eine große Wärmemenge gebunden hatte, diese Wärme allmählich freigibt und dem warmzuhaltenden Gefäßinhalt mitteilt.The keeping of heat by means of easily melting salts is based on a known method ensure that the salt mixture enveloping the vessel to be kept warm after it has been removed from which had melted the heat given off to the vessel by some heat source, and a large amount of heat as a result of this process had bound, gradually releasing this heat and the contents of the vessel to be kept warm notifies. Durch das Freigeben der Wärme kristallisiert das Salz wieder, und es tritt dabei der Übelstand auf, daß die ganze Salzmischung zu Klumpen erstarrt, welche die Gefäßwände beschädigen. When the heat is released, the salt crystallizes again and the The problem was that the whole salt mixture solidified into lumps which damage the walls of the vessels. Dies hat man zu vermeiden gesucht durch ein Verfahren, nach welchem dem Salz Glyzerin beigemischt wird, um die Klumpenbildung zu verhindern.Attempts have been made to avoid this by means of a process in which the salt is glycerine is added to prevent the formation of lumps. ao Dasselbe wird nun gemäß vorliegender Erfindung auf andere Weise erreicht, und zwar durch Beimischung von durch Fett- und Schleimgehalt sich auszeichnenden Pflanzensamen. Ein solcher Samen ist z. B. der Sonnenblumensamen, ferner besonders das sogen, »griechische Heu« (foenum graecum) u. a. Solcher Samen hat die Wirkung, daß dadurch die Salzmischung zu einer weichen, breiartigen Beschaffenheit kristallisiert, die außer für metallene Hohlräume auch für Kompressen und Umschläge aus Gummistoff sich eignet, während bei dem Glyzerinverfahren eine sandkörnige Masse auskristallisiert, welche von Gummistoff auf die Dauer nicht vertragen wird; überdies macht das Glyzerin das Gummi mürbe, was pflanzliche Stoffe, wie foenum graecum, nicht tun.ao The same is now achieved in a different way according to the present invention, namely by adding plant seeds that are characterized by their fat and mucus content. Such a seed is e.g. B. the sunflower seeds, also especially the so-called, "Greek hay" (foenum graecum) and others. Such a seed has the effect that thereby the salt mixture crystallizes to a soft, mushy texture, which except for metallic ones Hollow spaces are also suitable for compresses and envelopes made of rubber material, while with the glycerine process a sand-grained one Mass crystallizes out, which rubber cannot tolerate in the long run; moreover, the glycerine makes the gum crumbly, which vegetable substances, such as foenum graecum, do not. Das Verfahren ist folgendes: Der Samen wird in heißem Wasser aufgelöst und zu etwa 6 bis 7 Prozent des ganzen Volumens mit dem Salz vermengt.The procedure is as follows: the seed is dissolved in hot water and added to about 6 to 7 percent of the total volume mixed with the salt. Wegen der weichen Beschaffenheit des kristallisierten Salzgemisches wird bei Anwendung auf Gummikompressen die Gummihülle nicht beschädigt, wenn sie bei der Kristallisation durch Pressung ausgedehnt wird.Because of the soft nature of the crystallized salt mixture, when using on rubber compresses the rubber cover is not damaged when it crystallizes is expanded by pressing. Die Verwendung pflanzlicher Stoffe, wie foenum graecum, ist noch deshalb für Speisewärmer geeigneter als Glyzerin, weil es den Geruch des als Salzhülle zur Verwendung kommenden Salzes (z. B. essigsaures Natron), das durch seinen Geruch die Speisen unappetitlich machen könnte, verdeckt, während Glyzerin, welches geruchlos ist, denselben nicht verdeckt.The use of vegetable substances, such as foenum graecum, is more suitable for food warmers than glycerine because it does Smell of the salt used as a salt coating (e.g. sodium acetate), that could make the food unsavory due to its smell, concealed while Glycerine, which is odorless, does not cover it.
