6864469, Mar 8, 2005

Filed:

Sep 9, 2003

Appl. No.:

10/657077

Inventors:

Jeffrey R. Chaskin - Coral Springs FL, US

International Classification:

H05B006/10

US Classification:

219603, 219633

Abstract:

Dry cells are combined in both physical and electrical combination to fabricate a battery. A dry cell strap defined by a solid copper core with a skin or cover of chrome steel bonded to the copper core, is soldered to terminals of adjacent dry cells using induction heat developed by an oscillator/generator operating in the R F frequency range of frequencies. The parts of the dry cell terminal and cell strap which are soldered together are inserted into alignment with the coils of a coil which generates a magnetic field for inducing a heat creating current in the parts aligned with the coils. Virtually immediate temperature elevation throughout the parts in the coil is achieved and soldering is accomplished without applying excess heat to any one part thereof. Heat elevation in the parts to be soldered, is kept to a minimum. The increment of time during which the temperature of the parts is elevated is minimized.

Appl. No.:

10/827635

Inventors:

Jeffrey R. Chaskin - Coral Springs FL, US

International Classification:

B23K 1/00

US Classification:

219 8515

Abstract:

A method and apparatus is disclosed for fabricating a dry cell storage battery from a plurality of dry cells by soldering a battery strap to terminals of adjacent dry cells in a battery pack. A resistance heat solder apparatus is provided for soldering a joint defined by an end portion of a battery strap and a terminal of a dry cell, so that adjacent dry cells in the battery pack are in physical and electrical contact. Terminal probes, connected across the secondary coil of a step-down transformer, are used to make contact with the joint to be soldered for applying a voltage across the joint. Terminal probes have contoured tips. A preferred embodiment provides terminal probes which are contoured to be a mirror image of the contour of the joint where the particular terminal probe makes contact with the solder joint. Application of a voltage across the joint provides a collimated current flow path through the joint. An intense heat is created within the joint by the current flow.

Appl. No.:

10/431564

Inventors:

Jeffrey R. Chaskin - Coral Springs FL 33071

International Classification:

H01R 300

US Classification:

439500, 429178

Abstract:

A cell connector bar or strap for connecting or coupling electric cells, both electrically and physically, is provided with a heat-sink for dissipating heat generated by the cells when charging rechargeable cells and during rapid discharge of the battery formed by the coupled cells. The heat-sink, in its preferred structure is a plurality of heat dissipating elements, such as extending fingers, extending from the body of the cell connector bar.
