Abstract: A nozzle assembly for use with injection molding apparatus includes an outer sleeve having a relatively large bore extending from an open rearward end forwardly to a substantially closed forward end, and having an injection orifice therein. An inner nozzle tip is located within the sleeve, and has a radial flange and an internal extending from a rearward open end to a forward tip having a plurality of flow orifices upstream of the injection orifice. A manifold insert is located within the outer sleeve and includes a through bore in axial alignment with the bore of the nozzle tip. The manifold insert has a forward end which receives the nozzle tip and which abuts the radial flange. A coil heater is located radially between the manifold and the outer sleeve, a forward end of the coil heater seated on the radial flange. The manifold insert, nozzle tip and coil heater form a subassembly which is easily removed and reinserted vis-a-vis the outer sleeve.

Abstract: A multiple vent plug assembly for vent ports of an electrical storage battery, the assembly includes a gang vent insert having a base wall and an upstanding peripheral rim defining a pair of side walls and a pair of end walls; an overcap including an inner rib for engagement with the upstanding peripheral rim of the gang vent insert; the insert including first and second parallel partitions extending between the pair of side walls to thereby divide the insert into three vent chambers including end chambers on either side of a center chamber, each chamber having a hollow vent barrel extending downwardly from the base wall and terminating at a drain hole.

Abstract: A storage battery is provided which includes a casing and a cover secured to the casing. The cover includes a body having a top surface and a peripheral skirt; the top surface having a plurality of vent apertures, at least one negative terminal and at least one positive terminal, and an elongated recess having a bottom, four side walls and an open top. The negative and positive terminals have extensions exposed at opposite ends of the recess, and a state-of-charge indicator assembly is mounted in the recess and electrically connected to the negative and positive terminal extensions. The state-of-charge indicator assembly is sealed in the recess by relatively thin adhesive seal or membrane applied over the open top and adhered to the top surface of the cover. The membrane is provided with percent charge and test switch indicia thereon.

Abstract: A gang vent cap for commonly venting a plurality of cell apertures of a storage battery in which a vent cap having a cover and a base which define a selectively configured hollow enclosure. A venting path is defined within the hollow enclosure which interconnects one or more battery cell ports with the venting port of the vent cap. Associated with each battery cell port of the vent cap is a projecting battery engaging member which sealingly engages one of the cell apertures of a storage battery. Each cell port includes a splashguard disposed between the battery cell and the cell port to retard the ingress of battery acid into the vent cap. A cylindrical condensation chamber is defined within the hollow enclosure above each cell port to trap and condense battery acid contained in the gases venting from the battery cell. Pathways defined within the vent cap include primary and secondary acid retention chambers, a corridor system and a venting chamber.
