Abstract

The invention relates to the adaptation of scales with 2 or more measurement ranges in the manufacture of densimeters, aerometers, thermodensimeters and thermometers with or without ballasting, characterised in that it allows the use of two apparatuses to be obtained in a single apparatus and in that the measurement scale gives several types of indication.

Description

DESCRIPTION
La présente invention concerne l'adaptation d'échelles à deux ou plusieurs plages de mesure dans la fabrication de pèse liquides; plus précisemment de densimètres, d'aréomètres, de thermo densimètres et de thlermomètres avec ou sans lestage, permettant de réunir l'emploi. de deux appareils dans un seul appareil.DESCRIPTION
The present invention relates to the adaptation of scales to two or more measuring ranges in the manufacture of liquid scales; more precisely, hydrometers, hydrometers, thermo-densimeters and thermometers with or without ballasting, making it possible to combine employment. of two devices in one device.

ETAT DE LA TECHNIQUE
Certains tests de mesure effectués avec des densimètres tels que la pesée de l'acide des batteries pour déterminer la température de protection au froid notamment, nécéssitent l'emploi de deux aréomètres
Un densimètre pour la pesée de l'acide (fig 1 a) composé d'une tige W d'un corps 2 et d'un lest 2b dont l'ensemble représente un volume x e comportant une echelle de mesure lacée dans la tige et graduée soit en unités de densité
soit en zones indiquant l'état de charge de la batterie 4
second densimètre pour la pesée de l'antigel (fig 1 b) composé d'une tige 5 d'un corps 6 et d'un lest 6 dont l'ensemble représente un volume y e comportant une echelle de mesure lacée dans la tige et graduée soit en unités de densité 7 soit en zones indiquant le degré de protection au froid du radiateur(8)
Ces deux tests sont souvent effectués simultanément par l'utilisateur sur les éléments de sa voiture. I1 vérifie l'état de charge de la batterie à l'a ide d'une pipette (fig 2) constituée d'un corps 9 munie d'une poire 10 pour aspirer le liquide a tester, dans laquelle se trouve le pèse acide 10b, puis intervertit le pèse-acide avec le pèse-anti gel dans la men pipette en déboitant la poire, pour tester le radiateur. Cette opération comporte le désavantage suivant
Après le test, il reste toujours du liquide sur le densimètre et l'intervention manuelle liée au changement du flotteur est désagréable et dangereuse car l'acide des batteries est corrosif.STATE OF THE ART
Certain measurement tests carried out with hydrometers such as weighing the acid in the batteries to determine the cold protection temperature in particular, require the use of two hydrometers
A hydrometer for weighing the acid (fig 1 a) composed of a rod W with a body 2 and a ballast 2b, the assembly representing a fixed volume comprising a measurement scale laced in the rod and graduated either in density units
either in zones indicating the state of charge of the battery 4
second hydrometer for weighing the antifreeze (fig 1 b) composed of a rod 5 with a body 6 and a ballast 6, the assembly representing a volume ye comprising a measurement scale laced in the rod and graduated either in density units 7 or in zones indicating the degree of protection against cold of the radiator (8)
These two tests are often carried out simultaneously by the user on the elements of his car. I1 checks the state of charge of the battery with the help of a pipette (fig 2) consisting of a body 9 fitted with a bulb 10 for aspirating the liquid to be tested, in which the acid weigher 10b is located , then invert the acid scale with the anti-freeze scale in the men pipette by removing the bulb, to test the radiator. This operation has the following disadvantage
After the test, there is still liquid on the hydrometer and manual intervention related to changing the float is unpleasant and dangerous because the acid in the batteries is corrosive.

L'invention consiste à réunir l'échelle de mesure pèse-acide et pèse-antigel dans un seul densimètre (fig 3).The invention consists in combining the scale for weighing acid and weighing antifreeze in a single hydrometer (fig 3).

Il est composé d'un corps Q muni d'un ballast en plomb fondu 12, serti dans la partie inférieure par un retreint ou une boursouflure 13 suivant la demande de Brevet N 8202900 du même inventeur e d'une tige R contenant l'échelle de mesure 15 et fermée à son extrémité supérieure 16 le tout représentant un volume différent en longueur et en diamètre de deux modèles antérieurs.It is composed of a body Q provided with a ballast in molten lead 12, set in the lower part by a constriction or a blister 13 according to patent application N 8202900 from the same inventor e of a rod R containing the scale 15 and closed at its upper end 16, the whole representing a different volume in length and in diameter from two previous models.

Cela évite les manutentions pour l'utilisateur, quelque soit l'un où l'autre des deux liquides a tester.This avoids handling for the user, regardless of where either of the two liquids to be tested.

Ce procédé peut être adapté à d'autres utilisations tels que l'oenologie, l'imprimerie, entre autre. This process can be adapted to other uses such as wine-making, printing, among others.
