A heater unit for dispensing metered portions of molten lead includes a cavity capable of selectively receiving a metered portion of molten lead from the lead reservoir. The heater unit is moveable between a first position for receiving lead into the lead reservoir and a second position for dispensing molten lead from the cavity.

Heater unit for dispensing metered portions of molten lead

A method of dispensing metered portions of molten lead comprises the steps of providing a heater body with a lead reservoir that produces sufficient heat to form molten lead and providing a lead dispensing shuttle plate with at least two lead metered cavities that are filled with molten lead in a fill position. The heater body is movable between a dispense position and a feed position. At least one of the metered cavities releases the molten lead when the heater body is moved to the dispense position. In one aspect, the method comprises supplying a strip of lead so that when the heater body moves to the feed position, it receives a portion of the strip of lead. In another aspect, the method comprises injecting inert gas over the lead reservoir and into the dispensing metered cavity to prevent air from entering the metered cavity.

A battery container with battery plates contained therein is retained by a container positioner. A battery cover is retained by a cover positioner. Molten lead is retained within a lead dispenser/heater unit. The exposed areas of the lead dispenser/heater unit are preferably flooded with an inert gas to prevent drossing of the molten lead. A container heating platen is disposed on a top of the lead dispenser/heater unit and a cover heating platen on a bottom thereof. The container positioner brings the battery container in contact with the container heating platen and the cover positioner brings the battery cover in contact with the cover heating platen. Molten lead is dispensed into the battery cover; the lead dispenser/heater unit is withdrawn; and the battery container is sealed against the battery cover while the lugs of the battery plates are inserted into molten lead in the battery cover.

Battery assembling method

The present invention relates to methods and organisms for concentrating and recovering metals and minerals from aqueous media. In the inventive method, a eucaryotic aquatic organism capable of concentrating a metal or mineral is contacted an aqueous medium containing the metal or mineral, in order to concentrate the metal or mineral in the organism. Following concentration, the metal or mineral accumulated by the organism may be recovered. Sponges are very preferable organisms for isolating metals, e.g, gold and silver, from seawater.

An improved battery design which utilizes the cover of the container as a mold to simultaneously create a plurality of solid cast electrical circuits, including external terminals, all without welded connections. The battery cover includes a plurality of plate strap mold wells or mold wells which receive molten lead. Adjacent plate strap mold wells are separated by a partition wall. An aperture is formed in the partition wall which allows molten lead to flow between adjacent plate strap mold wells and connect thereof. Terminal mold wells have terminal apertures through which molten lead flows to form an external terminal with the aid of a external terminal mold. A meltable sealant material is pre-applied to the plurality of mold wells and which becomes fluid upon introduction of molten lead. Upon cooling, the sealant material prevents migration of electrolyte between mold wells. The sealant material also prevents electrolyte and gasses from leaking out of the juncture between the external terminals and the battery cover. The sealant material further has the advantage of flowing into the fusion junctures between the plate lugs and the plate straps. The plate lugs may also be pre-coated when bright metal clean with a flux laden sealant to prevent oxidation of the lugs and enhance fusion of the lugs to the plate straps. The sealant retaining the flux inhibits oxidation of the plate lugs. With this innovative method of battery manufacture, the battery is assembled and completely sealed in a matter of seconds.

A battery connection apparatus for gang-connecting batteries together includes a terminal on a battery and a connector coupled to the terminal. The connector and terminal are resiliently snap-fitted to one another. The apparatus employs what may be termed a 'ball-and-socket' arrangement in which a male portion (whether on the battery or on the connector) snap-fits into a female portion. Resiliency is provided by 'springy' split finger pieces or by a compressed resilient core-like component. Using the new apparatus, batteries may be gang-connected horizontally or vertically and, essentially, without the use of tools.

Method and apparatus for manufacturing storage batteries. The method is directed toward manufacture of a storage battery with a single weld between intercell connectors, positive and negative plates and external terminals. The apparatus comprises a frame, holding and positioning components, a lead dispensing assembly and an edge-heater assembly for sealing the battery case. The apparatus and inventive method permit dispensing of molten lead into selective segments of the battery case substantially simultaneously with sealing of the battery case.

An improved storage battery and method for manufacture. The battery includes a case with first and second walls, surrounding wall structure and partitions forming first, last and at least one middle cells, each containing a group of positive and negative plates and electrolyte. The first wall inner surface forms positive and negative lead-containing wells in alignment with the wells of adjacent cells, and an intercell connector across each partition and held in fluid-tight engagement with the case in position to electrically connect the lead in one well of a middle cell to the lead in a well of the adjacent cell. The method of manufacture includes molding plastic to form a case having first walls, second walls, surrounding wall structure and partitions to form first, last and at least one middle cell, the first wall having positive and negative wells which extend to the partitions and are in alignment with the negative and positive wells, respectively, of the adjacent cells; placing an intercell connector across each partition; pouring molten lead into each well so that the lead in each middle cell engages an intercell connector; inserting a cell group of plates into each cell, the plates having portions immersed in the molten lead in the wells before hardening; and closing the container by sealing an opposed second wall to the side walls.

Storage battery and method of manufacture

A method for manufacturing storage batteries including: molding plastic to integrally preform bottom and side walls and partitions to form first, last and at least two middle cells, the bottom wall having upwardly projecting ridges with upper edges below the electrolyte fill level forming positive and negative wells which extend to the partitions and are in alignment with the negative and positive wells, respectively, of the adjacent cells; placing an intercell connector across each partition below the fill level to be held by the case in position extending from one middle-cell well to a well in the adjacent cell; pouring molten lead into each well, the lead in each well of each middle cell engaging an intercell connector; inserting a cell group of plates into each cell, the plates having lower portions immersed in the molten lead in the wells before hardening; and closing the container by sealing a top wall to the side walls. This allows cells to be completely sealed from one another at positions below the fill level and each intercell connector to interconnect the lead in opposite-polarity wells of adjacent cells.

Disclosed is a cable connector in which a body portion has an anchor and anchor connector. A cable clamp of flat material with threaded edges at one end is provided with an interior cable grip in the form of a hole. A cable clamp slot is provided in the body of the connector to receive the flat cable clamp. After the strand end of the cable is inserted into the cable grip hole, a cable clamp nut threadedly engages the nut threads of the cable clamp and moves the clamp into a tight gripping relationship with the cable. In assembling, the cable clamp is force-fitted into the cable clamp slot. To assure alignment, and deburring so that the strand end of the cable will enter the connector easily, a tool is employed to align the cable clamp hole with the cable tube portion of the body, while at the same time deburring the table clamp.
