The invention realizes an improved sealing unit for the electrolyte of electric batteries which includes a container which is closed through a cover. The cover is provided with annular elements circumscribing the holes which let the poles pass by and be coupled to the elements which are housed in the container. The sealing unit includes a tubular ring nut which is coupled in the interspace existing between the pole and the hole, and which cooperates with at least a first sealing gasket. The first sealing gasket is included between the pole, the cover and the ring nut, and realizes with them an annular sealing area.

The finding provides a hanger made of plastic, including a main body substantially symmetrical to a central part holding the support hook, said body having two arms sloping down from the center towards their ends. Said hanger has a mass of first flexible elements, protruding from the upper surface of said arms and incorporated in said arms during the molding of the hanger such that they prevent the hanging garments from slipping.

An automatic re-fill device includes a body portion adapted to be secured in the accumulator lid and a tubular element having a lower float portion and being slidable within the body. The tubular element has a closure device within the body and a membrane at an upper portion thereof for increasing upward pushing force to close the closure when the float is lifted by the liquid in the accumulator.

The invention is a container for storage batteries including a box (3, 20) provided with one or more cells, each of which is suitable to receive metallic plates (10) dipped in the electrolyte and connected to each other so as to make up a positive pole and a negative pole, a cover (2, 30) closed on the box along the perimetrical edge of said box, characterized in that each cell (3, 11, 12, 13) of said container has at least an electrolyte feed pipe (7, 14, 16, 18) with one end communicating with the opening made on the cover and with the other placed near the bottom of the box, and at least a level pipe (5, 15, 17, 19) of said electrolyte with one end communicating with the opening made on the cover and with the other end coinciding with the electrolyte level inside every cell.

The invention discloses an element (1; 201) to cover the connectors (2) connecting the poles (31, 32) of the elements of an electric accumulator (3) and consists of a hollow body (10) which receives the body (20) of one of said connectors (2). At least one part of said hollow body (10) presents a shaped profile (17) suited to realize an elastically flexible structure which allows the variation of the length of said covering element (1), whenever it is strained by an axial force (18). Said variation of length allows the coupling of the same covering element (1; 201) with connectors (2) presenting lengths differing from one another.

A box made of plastic material, particularly suited to contain floppy discs for electronic processors, consists of three elements (10, 20, 30) connected to each other by means of two hinges being in common and coaxial. One element (30) functions as a lid when the box is closed and as a support when the box is open; the other two elements (10, 20) are hinged to each and can be opened according to a certain angle, they are provided with a bottom plate consisting of two comb-shaped parts (14, 24) with rectangular teeth; the fixed angle of aperture between the two elements (10, 20) forming the useful space of the box, is obtained by the superimposition of a projection (39) being present on the end bent part of one element (10) of the box and on the corresponding indentation (26) being present on the other element (20) being connected to it.
摘要:
The cell-container, obtained by blow-forming, thus having a minor thickness, presents at the upper-rim a conformation in two steps (1) permitting the mating of the cell-lid to the cell-container remaining within unified overall-dimensions, as the welding-bead between the cell-lid and the cell-container forms itself on the inside instead of on the outside of the same. Furthermore, it becomes possible to increase the welding-surface according to one's need if the cell-container is cut in correspondence with the flat-part of the step. The cell-container presents, furthermore, horizontal-recessings at various levels permitting the modular-cutting of the product according to unified measures.The cell-lid's form is concave towards the exterior in order to follow the dilatations of the poles during the service-life of the battery. The cell-lid is also furnished with a molded ring, which has a circular profile around the electrolyte's inlet thus avoiding the application of a gasket onto the top-cover.

The finding produces a container for batteries comprising an open, prism-shaped case, with its inside having a series of vertical baffles suited to creating chambers for the cells of said battery and having a watertight cover coupled to it, which holds the battery terminals, where at least the case of said container is made by moulding propylene-bonded mica in granular powder, said addition of powder being in the region of 5-50% by weight.
摘要:
A lid for accumulator batteries has one or more holes to receive a device to ensure the circulation of electrolyte during the first charge and a second device to ensure the re-fill of electrolyte during the other charges. The lid is equipped with one or more channels each having one end facing the surface of the one or more holes and the opposite end coupled with at least one duct on the inner vertical wall of the container.
