Appl. No.:

11/344889

Inventors:

Michael A. Goldman - Sunrise FL, US

Assignee:

Mechanical Manufacturing Corporation - Sunrise FL

International Classification:

B01D 29/11
B01D 29/27
B01D 39/16
B01D 29/00
B01D 39/00

US Classification:

21049701, 210499, 2105021

Abstract:

A filter bag for use in a liquid filtering system is provided. The filter bag comprises a filtration layer. The filtration layer is defined by one or more filter mediums. The filter mediums can be composed of an adsorbent material disposed between two thin wall substrates. The adsorbent material can be a granular activated carbon. The thin wall substrates can be selected to be highly porous thin wall substrates. The filter bag can further comprise one or more diffusion mediums. The diffusion mediums can be defined by a woven or a non-woven mesh material. The mesh material can be selected from a suitable material that is temperature and fluid compatible with the filtering application to be carried out. The filter bag can include alternating layers of medium having one or more filter mediums and one or more diffusion mediums.

Mechanical Manufacturing Corp. - Sunrise FL

International Classification:

B01D 37/00
C02F 1/00
B01D 29/00

US Classification:

210806, 210767, 210335

Abstract:

A method is provided for filtering a fluid. The method includes the step of selecting a first surface filtration medium to include layers of a first mesh material (FMM). The method also includes the step of selecting a second surface filtration medium to include layers of a second mesh material (SMM). The layers of FMM are selected to include a first number of layers (FNL) for collectively providing a first absolute micron filter rating (FAMFR) and a first capacity for collecting a first type of particles. The layers of SMM are selected to include a second number of layers (SNL) different from the FNL. The SNL is selected for collectively providing a second absolute micron filter rating (SAMFR). The SAMFR is different from the FAMFR. The SNL is also selected for providing a second capacity for collecting a second type of particles.

International Classification:

H03K 1700

US Classification:

307304

Abstract:

The gate insulator of an IGFET, whose gate is connected to the input terminal of a circuit, is protected by limiting the potential difference between any two circuit terminals. Each input and output terminal of the circuit is connected via protective diodes to the power supply lines of the circuit and a high conductivity, low reverse dynamic impedance, diode is connected between the power supply lines. The reverse voltage across the high conductivity diode is less than that of any other diodes at a given current level, whereby only the high conductivity diode conducts substantial currents in the reverse direction.
