Filed:

Nov 1, 2001

Appl. No.:

09/999337

Inventors:

John R. Martin - Naples FL
David C. Nethercot - Naples FL

Assignee:

Cape AeroSpace - Cape Coral FL

International Classification:

F41A 1900

US Classification:

42 84, 89 2805, 89 281, 89135

Abstract:

An electric charging system for a firearm includes a port in operable communication with a chamber adapted to receive an amount of expanding gas created by an ignited charge, and a cavity in operable communication with the port and adapted to receive an amount of the expanding gas therefrom. The charging system also includes a charging assembly in operable communication with the cavity, wherein the charging assembly creates an electric charge when impinged by the expanding gas located within the cavity, and a conductor in electrical communication with the charging assembly, wherein the conductor receives the electrical charge from the charging assembly. The charging system further includes a power storage unit in electrical communication with the conductor, wherein the storage unit stores the electrical charge received from the conductor.

Abstract:

A single, reverse osmosis membrane system having a double-pass, product-staged design using first and second banks of membranes in series, with excessive pressure supplied by the pump to the feed to the first bank so that the concentrate flow from the first bank will be at sufficient elevated pressure to drive a turbocharger for increasing the low pressure product flow sufficiently to pass through the second bank of membranes, the excess pressure on the first bank being balanced by increased osmotic pressure from feedback of concentrate flow from at least one of the banks to the feed supply. Preferably, part of the concentrate flow from the first bank is dried on a double drum dryer or a single drum flaker for recycle use or disposal. The membranes for the first set are high rejection, high pressure membranes. The membranes for the second set are low rejection, low pressure membranes.
