Description

Uppfinnare: R Sabourin Prioritet begard freuz den 4 mars 1959 (Freida-Hee) Foreliggande uppfinning avser en varmeutvecklande anordning, som kan anyandas ett obegra,nsat antal ganger och bestar av en papiljott for harlaggning. Inventor: R Sabourin Priority requested on March 4, 1959 (Freida-Hee). The present invention relates to a heat generating device which can be used an unlimited number of times and consists of a hair curler.

Automatiskt varmentvecklande papilj otter for harpermanent aro kanda, vilka besta av en kropp, som är ihalig for att upptaga en borttagbar eller utbytbar patron, vilken är fylld med ett material, som kan Astadkomma en exotermisk reaktion, da patronen anvandes. Automatic heat-developing papilla for harpermanent aro kanda, which consists of a body which is hollow to receive a removable or replaceable cartridge, which is filled with a material which can produce an exothermic reaction when the cartridge is used.

Fyllningen kan besta antingen av tva reagerande medel, av vilka det ena är ett fast amne och det andra en vatska, t. ex. CaO och vatten, eller av ett s. k. redox-system bestaende av ett oxiderbart amne och ett reduktionsmedel, t. ex. metalliskt aluminium oak natriumpersulfat, vilka arnnen trada i reaktion vid anvandningen och darvid avgiva en varmemangd motsvarande den, som frigiires genom motsvarande exotermiska reaktion. The filling may consist of either two reactants, one of which is a solid substance and the other a liquid, e.g. CaO and water, or of a so-called redox system consisting of an oxidizable substance and a reducing agent, e.g. metallic aluminum oak sodium persulphate, which are reacted during use and thereby emit a heat mant corresponding to that which is released by the corresponding exothermic reaction.

Automatiskt varmeutvecklande patroner av detta slag, vilkas arbetsprincip baserar sig pa icke reversibla exotermiska reaktioner, kunna aldrig anvandas mera an en gang och maste kastas bort efter anvandningen, varfor de i langden stalla sig mycket dyra att anvanda. Dessutom maste patronernas dirnensioner vara begransade och foljaktligen den exotermiska fyllningen hallas synnerligen ii-ten Mr att papiljotternas volym skall kunna hallas inom ett acceptabelt varde. Automatic heat generating cartridges of this kind, the working principle of which is based on non-reversible exothermic reactions, can never be used again and must be discarded after use, so that in the long run they are very expensive to use. In addition, the dimensions of the cartridges must be limited and consequently the exothermic filling is kept extremely high in the Mr. That the volume of the curlers must be able to be kept within an acceptable value.

Genom uppfinningen kunna dessa olagenheter undanrdjas och en effektiv, varmeutvecklande anordning astadkommas, vilken kan anvandas ett obegransat antal ganger. By means of the invention, these imperfections can be eliminated and an efficient, heat-generating device can be provided, which can be used an unlimited number of times.

Enligt uppfinningen bestar den varmeutvecklande anordningen vasentligen av en tat behAllare, t. ex. en patron, en tub, en dosa eller ett liknande foremal, innehallande en fyllning av en massa, som kan frigka varme genom en reversibel omvandlingsprocess vid anvandningen. According to the invention, the heat generating device essentially consists of a tat container, e.g. a cartridge, a tube, a box or a similar object, containing a filling of a mass, which can release heat by a reversible conversion process in use.

Enligt en lamplig utforingsform av den varmeutvecklande anordningen enligt uppfinningen inn.ehaller behallaren en massa, som kan upptaga varme fran en yttre kalla genom en reversibel omvandlingsprocess och i sin tur ateravgiva detta varrne till omgivningen genom en motsatt omvandlingsprocess. According to an exemplary embodiment of the heat generating device according to the invention, the container contains a mass which can absorb heat from an external cold through a reversible conversion process and in turn return this heat to the environment through an opposite conversion process.

Den reversibla omvandlingsprocessen kan vara en reversibel fysikalisk omvandling, t. ex. en process innefattande smaltning och stelning, forangning och kondensation, etc., som atfoljes av en varmeupptagning i den ena omvandlingsriktningen och en varmeavgivning i den andra omvandlingsriktningen. The reversible transformation process may be a reversible physical transformation, e.g. a process comprising melting and solidification, evaporation and condensation, etc., which is accompanied by a heat absorption in one direction of conversion and a heat dissipation in the other direction of conversion.

De reversibla reaktionen kan pa samma salt vara en reversibel kemisk omvandlingsprocess, antingen en kemisk reaktion, som är endotermisk i den ena omvandlingsriktningen: och exotermisk i den andra, eller en periodisk kemisk omvandling, som ater fullstandigt avger det under namnda omvandling upptagna varmet. The reversible reaction on the same salt can be a reversible chemical conversion process, either a chemical reaction which is endothermic in one direction of conversion: and exothermic in the other, or a periodic chemical transformation which completely gives off the heat taken up during said conversion.

Enligt en speciell utforingsforni av uppfinningen är den massa, som anvandes sasom varmegenerering eller varmeackumulator -vid omgivningens temperatur fast och har ett Mgt latent smaltvarme, Mgt specifikt varme och lamplig smaltpunkt, foretradesvis under 100° C. According to a particular embodiment of the invention, the pulp used as heat generation or heat accumulator is fixed at ambient temperature and has a very latent heat of fusion, very specific heat and suitable melting point, preferably below 100 ° C.

Uppfinningen beskrives narmare i det fOljande med han.visning till bifogade ritning, som visar en speciell utforingsform av en varmeutvecklande anordning enligt uppfinningen, som kan anvandas sasom papiljott fOr harlaggning. The invention is described in more detail below with reference to the accompanying drawing, which shows a special embodiment of a heat-generating device according to the invention, which can be used as a curling iron for hair-laying.

Ritningen visar en langdsektion av denim utforingsform. Sasom visas pa ritningen be-star den varmeutvecklande anordningen en- 2— — ligt uppfinningen av en tubformad patron 1 av plast, t. ex. polyeten, innehallande en fyllning 2 av vattenhaltig natriumhydroxid med foljande egenskaper: smaltpunkt 64° C smaltvarme 80 cal/kg. The drawing shows a long section of denim embodiment. As shown in the drawing, the heat generating device according to the invention consists of a tubular cartridge 1 of plastic, e.g. polyethylene, containing a filling 2 of aqueous sodium hydroxide with the following properties: melting point 64 ° C melting heat 80 cal / kg.

Patronen tillslutes av en kapsyl 3, som eventuellt kan hop svetsas med patronen, sedan fyllningen inforts. The cartridge is closed by a cap 3, which can possibly be welded together with the cartridge after the filling has been introduced.

Namnda f8rening kan an-vandas I olika form, sasom pulver, kristaller, fj all, tabletter eller snad bitar. Man kan ocksa anvanda natriumhydrid eller natriumacetat i stallet for natriumhydroxid eller ocksa helt andra fyllningar tried ovan angivna egenskaper. Said compound can be used in various forms, such as powders, crystals, foils, tablets or cut pieces. It is also possible to use sodium hydride or sodium acetate instead of sodium hydroxide or also completely different fillings with the above-mentioned properties.

Alternativt kan patronen utforas i nietall, som icke angripes av den anvanda fyllnadsmassan eller som skyddas mot denna genom en belaggning eller genom oxidering eller dylikt. Alternatively, the cartridge can be made in numbers which are not attacked by the filling mass used or which are protected against it by a coating or by oxidation or the like.

Den beskrivna varmeutvecklande anordningen kan med fardel anvandas sasom papiljott f8r harldggning. The described heat generating device can be used as a curling iron for hair removal.

For detta andarnal inneslutes patronen i ett bestandigt cylindriskt holje 4, som gar det lattare att linda om harslingan och fixera den. For this breath, the cartridge is enclosed in a permanently cylindrical housing 4, which makes it easier to wrap around the resin loop and fix it.

Da den salunda utforda papiljotten skall anvandas, doppar man den i varmt vatten eller utsatter den for nagon annan till buds staende yttre vfirmekalla. Fyllningen upptager snabbt varme ur det varma vattnet och hojer pa detta salt sin varmepotential samt andrar sitt fysikaliska tills-land genom smaltning, om uppvfirmningsvattnets temperatur at- hogre an fyllningens smaltpunkt. When the well-challenged curling iron is to be used, it is dipped in hot water or exposed to another available external cold. The landfill quickly absorbs heat from the hot water and increases its heat potential on this salt and changes its physical surface area by melting, if the temperature of the heating water exceeds the melting point of the landfill.

Papiljotten 1 lyftes upp, vattnet Mr avrinna frail den, om tillfdlle hdrtill finnes, varpa den appliceras som en vanlig papiljott for larlaggning. Den av patronen ater avgivna varmen under den motsatta forandringen av fysikaliskt tillstand genom fyllningens stelnande i patronen dr tillracklig och varar tillrdckligt lange fOr att ge tillfredsstallande resultat. Salunda kan exempelvis en patron med en fyllning av natriumhydroxid uppvarmd till 64° C bibehalla en temp eratur over 40° C under minst en halvtimme, varunder man hinner utfOra en fullstandig harlfiggning. The curler 1 is lifted up, the water Mr drains frail it, if there is an opportunity to do so, warp it is applied as a normal curler for larval laying. The heat emitted by the cartridge again during the opposite change of physical state due to the solidification of the filling in the cartridge is sufficient and lasts long enough to give satisfactory results. Thus, for example, a cartridge with a filling of sodium hydroxide heated to 64 ° C can maintain a temperature above 40 ° C for at least half an hour, during which time a complete harling is performed.

Uppfinningen dr emellertid ej begransad till de detaljer, som behandlats i ovanstaende beskrivning, vilken endast givit belysande exempel pa uppfinningens praktiska utforande. Man kan salunda vidtaga olika lampliga modifikationer utan att darfor ga utanfor uppfinningens ram. Exempelvis kan man i stallet for en reversibel reaktion av typen smaltning-stelning anvanda en process av typen forangning-kondensation eller en reversibel kemisk reaktion av tidigare namnt slag. However, the invention is not limited to the details discussed in the above description, which has only given illustrative examples of the practical embodiment of the invention. Thus, various modifications may be made without departing from the scope of the invention. For example, in the place of a reversible reaction of the melt-solidification type, a process of the evaporation-condensation type or a reversible chemical reaction of the previously mentioned kind can be used.

Pa samma salt kan man andra formen pd patronen 1 f8r att anpassa den varmeutvecklande anordningen for andra andamal. On the same salt one can change the shape of the cartridge 1 to adapt the heat generating device for other purposes.

Temperaturforhojningen kan ocksa astadkommas pa annat salt an genom en yttre varmekalla, exempelvis genom ett elektriskt motstand inbaddat i patronen och inkopplingsbart medelst anslutningskontakt till ett ledningsnat. The temperature increase can also be effected on another salt than by an external heating source, for example by an electrical resistor embedded in the cartridge and connectable by means of a connection contact to a wiring harness.

Da man anvander rengoringsmedel eller giftiga amnen, sasom natron, kan man forsatta dessa amnen med fargade indikeringsmedel, t. ex. metylenblatt, sd att man latt kan avsloja alla lackor, till och med de aura minsta, nar papiljotten doppas i vattnet. When using cleaning agents or toxic substances, such as baking soda, these substances can be continued with colored indicating agents, e.g. methylene sheet, so that you can easily reveal all the paints, even the aura smallest, when the curler is dipped in the water.
