摘要:
A valved filling head for filling a container with a viscous flowable product includes means for introducing a controlled blast of fluid through the head toward the fill opening or spout of the container at the end of the fill cycle. The fluid stream is directed against accumulated viscous material in the fill opening, in order to push the viscous material down into the container away from the spout and to prevent splattering of the material onto the container and over filling apparatus when the head and spout are separated and the opening is capped.
摘要:
A tap for dispensing liquids, essentially constituted by a body (1) for mounting in the outlet of a receptacle and for dispensing liquid, in a rigid manner, by a flap or a sealing closure member (2) for an opening (3) for dispensing the liquid, provided with a control member (4) and disposed in the portion of the body (1) opposite that for mounting in the outlet, and by an actuating device (5) for the control member (4). The body is made of a composite material by conjoint injection or co-molding in a single molded piece integrating the actuating device (5) for the control member (4) of the flap or of the sealing closure membrane (2) of the opening (3) for dispensing the liquid, by spring force, via a resiliently deformable membrane constituted by a flexible material with permanent spring effect, the rest of the body (1) being constituted of a rigid material.
摘要:
A negative battery plate is constructed from a light weight, non-conductive grid by providing the grid with an initial minimal degree of conductivity and then pasting the grid with relatively non-conductive metal oxide battery paste. The minimal conductivity of the grid is utilized to initiate the conversion of the metal oxide paste to the elemental metal by electrolysis in a suitable electrolyte. The grid may contain only a single conductive lug in contact with the paste or may additionally contain one or more wires connected to the lug and passing through the interior of the grid. Alternatively, a thin coating of the elemental metal may be deposited on the grid before application of the paste. In accordance with another embodiment, an inert grid filled with oxide paste may be converted to metal by pressing a separable conductive member against the grid and battery paste during electrolysis. The minimal conductivity of the freshly prepared plate is sufficient to initiate the electrolysis, and the reaction rate accelerates as the conversion to metal proceeds, due to the progressively increasing conductivity of the plate.
