Abstract: Method and device for packaging and dispensing a fluid product (P) contained in a receptacle (2) which is pressurized with the aid of a propellant gas (G), the receptacle (2) including two compartments (3, 4) which are separated by a moving partition (5), a first compartment (3) containing the fluid product (P) and being in communication with a valve (6) for dispensing the product (P) and the second compartment (4) containing the propellant gas (G), by which in the second compartment (4) the propellant gas (G) is brought to a pressure P1 allowing the fluid product (P) to be dispensed by action on the dispensing valve (6), dispensing is carried out and the pressure in the second compartment (4) is lowered to atmospheric pressure, the pressure in the compartment (4) not being brought back up to a pressure allowing dispensing of the product (P) until just before the next dispensing act.

Abstract: A packaging container of the aerosol type, which can be recharged with compressed gas, comprising an outer casing capable of being connected with a filling adaptor provided at its outer end with means for connection to a compressed gas source and connected on the inside to a filling tube whose free end opens inside the casing of the container above the level of the liquid contained in the latter.It comprises, mounted at the free end of the filling tube (7), a sealing device (9) arranged in the form of a case (10, 14) comprising a chamber (19) delimited between a lower wall (11) and an upper wall (15), the chamber communicating with the internal volume of the casing through at least one orifice (16) made in the upper wall (15), and with the filling tube (7) by orifices (12) made in the lower wall (11) outside a central part of the latter, and, inside the chamber (19), an elastic diaphragm (20) immobilized in its central part against the central part of the lower wall (11).

Abstract: A battery of series-connected storage cells is checked by:Measuring the transient elementary open-circuit voltage at the terminals of each storage cell;Comparing the said elementary voltages with the average transient voltage of the said storage cells (i.e. with the total transient open-circuit voltage divided by the number of storage cells). The battery is rejected if the difference between the said average transient voltage and one of the said elementary transient voltage becomes greater than a predetermined threshold.BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a method and a device for checking a storage battery, more particularly a lead acid storage battery, charged and filled with electrolyte, this checking being effected in principle when the battery comes off the production line.2.

Abstract: A method of checking a storage battery with series-connected cells comprises the steps of:Passing a charging current pulse through the battery,Measuring an elementary transient voltage at the terminals of each storage cell; andComparing elementary transient voltages with the average transient voltage of the said storage cells (total transient voltage divided by the number of storage cells).The battery is rejected if the absolute value of the difference between the said average transient voltage and one of the elementary transient voltages, when the difference maintains a constant sign, becomes higher than a predetermined threshold and, when the difference changes signs, if the sum of the maximum absolute values of the differences in constant sign becomes higher than a predetermined threshold. Application: checking lead-acid storage batteries when they come off the production line.

Abstract: A separator for a galvanic element wherein partially fused glass fibers are coated by a coating consisting of grains of thermo-hardening synthetic material immersed in a natural or synthetic latex to mechanically reinforce the knots in the glass fiber network resulting from partial fusion of the glass fibers without blocking the pores of the partially fused fiber network.
