  • Patent number: 10702629
    Abstract: A fat conditioning apparatus includes a conditioning vessel enclosing a conditioning chamber and a displacable plug. The conditioning chamber is bounded on one end by the displacable plug and has a variable volume that is a function of the position of the plug within the conditioning vessel. The apparatus has utility in a fat conditioning method, wherein the conditioning chamber contains a harvested fat emulsion. A washing liquid is injected into the conditioning chamber and mixes with the harvested fat emulsion, thereby displacing the plug in an outward expansion direction and expanding the variable volume of the conditioning chamber. The resulting mixture of harvested fat emulsion and washing liquid is stratified in the conditioning chamber into a contaminant-lean fat fraction and a contaminant-rich remainder fraction. The fat fraction, which is substantially free of the remainder fraction, is recovered from the conditioning chamber as a desired product of the method.

  • Patent number: 10406265
    Abstract: A method and device for isolating tissue cells from a liquid is provided for integrating a mixture of the tissue cells and the liquid into a vacuum stream and isolating again from the vacuum stream in a tissue collection container (13). The tissue cells are filtered out of the mixture by means of gravity and the remaining liquid is re-integrated into the vacuum stream. In order to further develop said method and device to improve the care of the tissue cells and to reduce the filtration time, the vacuum stream that is isolated from the mixture inside the tissue collection container (13) is temporarily interrupted in order to generate a pressure that also acts on the mixture. In terms of the device, the connection between the lower collection chamber (23) for the liquid and the upper vacuum chamber (25) is formed by a blockable bypass line (27).

A solid wall float tube in a drainage space has an open lower end and open upper end and is movable between a lowered position and a raised position. As the housing fills, water level in the housing rises to cause the solid wall float tube to move to the raised position and a negative pressure draws fluid through the filter medium. As water level outside the filter cartridge drops, air enters the housing and causes the solid wall float tube to drop to the lowered position, and filtered water in a fluid reservoir backflows through the filter medium while air enters the housing by passing upward through the solid wall float tube so as to enhance rate of backflow.

  • Publication number: 20120318753
    Abstract: A vacuum filtration device includes a removable power unit that includes a vacuum pump. The vacuum pump functions in one mode to remove hot oil from a fryer and to draw the oil into a container. The hot oil is fed through a filter located within the container that removes sediment. The filtered oil is then returned to the fryer through a pick-up opening and a hose by turning off the vacuum pump and in place creating a pressure inside the canister. A valve allows for transfer of the hot oil to and from the unit. A hose and nozzle assembly transports the hot oil the vacuum filtration device. The vacuum filtration device is mobile on a cart that may feature wheels and a handle.

  • Patent number: 8268179
    Abstract: A liquid vacuuming and filtering device may include a container having a sealed interior, a vacuum pump connected to the interior, a two-way valve connected to the interior, a flexible hose connected to the valve, a filter positioned within the interior and connected to the valve and a standpipe positioned within the interior and connected to the valve. The pump may be adjusted to a filling configuration, in which the pump evacuates the container interior to a pressure below ambient, causing fluid to be drawn through the hose, valve, and filter, which collects suspended particulates; or to a discharge configuration, in which the pump pressurizes the interior to a pressure above ambient, wherein the valve is adjusted to allow filtered fluid within the container to flow through the standpipe, valve and out through the hose.

  • Patent number: 8235221
    Abstract: Liquid filter assemblies including an upper sample reservoir, a sample filter and a lower storage bottle are supported by a vacuum base. The base has a vacuum inlet port and, for connection to the liquid filter assembly, a vacuum outlet port. A vacuum is provided through the base to below the sample filter to draw sample liquid through the sample filter into the storage bottle. The base may include an auxiliary vacuum outlet port for connection with additional devices. The bases may be connected from one to another through auxiliary vacuum outlets and the vacuum inlets to make a chain of liquid filter assemblies supplied from one vacuum source. Alternatively, one base may include multiple vacuum outlet ports so that it may support and supply vacuum to a plurality of liquid filter assemblies.

  • Patent number: 8231012
    Abstract: A method of removing a filtrate storage bottle from a water bath includes inserting at least two finger underneath a radially protruding lip of a filtrate storage bottle sealing cap and raising the at least two fingers to lift the bottle from the water bath. A side wall portion of the filtrate storage bottle sealing cap is smaller in perimeter than a circle surrounding the radially protruding lip. The cap creates a liquid tight seal with the filtrate storage bottle.

  • Patent number: 8158009
    Abstract: A flow diverter, vacuum control and tilting of the liquid filtering system are used alternatively or in conjunction to reduce foam production in a filtered liquid sample. A liquid filtering system includes an upper sample reservoir, a filter and a lower storage bottle. A vacuum is applied below the sample filter to draw sample liquid through the sample filter into the storage bottle. A flow diverter may be used to direct flow of the filtered liquid sample onto a sidewall of the storage bottle or guide flow to a bottom of the storage bottle. The vacuum may be regulated to reduce foaming. The liquid filtering system may be tilted to direct fluid to the sidewall of the lower storage bottle and reduce foaming.
