Abstract: The present invention relates to a system and method for providing a filter to prevent contamination of vacuum pumps during use with freeze dryers. The system and method comprising of a vacuum pump connected to a freeze dryer, the vacuum pump evacuating pressure from the freeze dryer; the vacuum pump connected to a coalescing filter at least partially collects water vapor and the particulate gas, whereby the particulates in the particulate gas are at least partially separated from the gas, the coalescing filter further separating the oil from the water and particulates, whereby the oil is rejuvenated for use with the oil composition; an oil control valve to control pressure in the system and maintain a level of oil in the vacuum pump; a drain valve to enable draining of impurities, and a final filter that injects air into oil exchanged between the sedimentary filter and vacuum pump.

Abstract: An assembly and method for gravitationally separating gold from particles, and specifically for separating small components of gold, less than 1 millimeter from small particles. A series of sieves having graduated mesh sizes, and arranged in a sequential, stacked configuration sieves the aggregate of large particles and larger components of gold. The remaining small particles and smaller components of gold fall into a container. A pressurized column of fluid is forced into the container. The fluid has sufficient flow velocity to suspend the lighter small particles, but insufficient flow velocity to support the denser, high specific gravity gold. Gold has a large specific gravity relative to the fluid and particles. Gravity causes the gold to falls into a transparent collection conduit. Manipulation of valves enables gold to redirect to a collection bin. Fluid flow is shut, enabling small particles to be flushed out through gravitational forces and excess fluid momentum.

Abstract: A system and method for providing a filter to prevent contamination of a vacuum pump during use with a freeze dryer. The method comprises evacuating, with a vacuum pump, pressure from freeze dryer; monitoring level of oil in reservoir; circulating oil between a sedimentary filter and a coalescing filter, and the vacuum pump, whereby a low pressure generated by the vacuum pump enables flowage of the oil; collecting condensation and water vapor that evaporates from oil through an exhaust hose; collecting, in the sedimentary filter, rust, particulates, and water from oil; collecting, in coalescing filter, water vapor and particulate gas to coalesce water vapor and particulate gas into oil, water, and particulates; separating, in coalescing filter, oil from water and particulates, whereby oil is rejuvenated; injecting clean air into rejuvenated oil; and turning the vacuum off and allowing remaining oil in the static system to return to vacuum pump reservoir.
