International Classification:

H03K019/177

US Classification:

326 41, 326 38

Abstract:

A field programmable gate array (FPGA) has plural columns of run-time memory provided in each of one or more partitions. Each column of run-time memory has a plurality of configurable memory blocks (CMB's). Each CMB is programmably configurable at least into a shallow-and-widest mode where data words have a maximum bit width and into a deep-and-narrowest mode where data words have a minimum bit width. Each CMB spans plural interconnect buses and the bits of its widest data words are distributed among the spanned interconnect buses. When a deep-and-narrow mode is invoked, CMB's of alternate columns operate in complementary fashion so that bits of narrowed words from one CMB move through a first subset of the interconnect buses while bits of narrowed words from a second CMB, in an alternate column, move through a second subset of the interconnect buses, where the second subset is mutually exclusive of the first subset of the interconnect buses. On the other hand, when the shallow-and-widest mode is invoked, the bits of the wide words of CMB's in alternate columns shared interconnect buses on an overlapping basis. In one embodiment, the shared interconnect buses are tri-statable.

International Classification:

B01D 15/00
C02F 1/44

US Classification:

210640, 2103218, 210175, 95 52

Abstract:

The invention is a pervaporation process and pervaporation equipment, using a series of membrane modules, and including inter-module reheating of the feed solution under treatment. The inter-module heating is achieved within the tube or vessel in which the modules are housed, thereby avoiding the need to repeatedly extract the feed solution from the membrane module train.

US Classification:

95 50, 95 52, 210640, 96 14

Abstract:

Processes for dehydrating an organic/water solution by pervaporation or vapor separation using fluorinated membranes. The processes are particularly useful for treating mixtures containing light organic components, such as ethanol, isopropanol or acetic acid.

Abstract:

Processes for removing water from organic solvents, such as ethanol. The processes include distillation in two columns operated at sequentially higher pressure, followed by treatment of the overhead vapor by one or two membrane separation steps.

International Classification:

C12P 7/14

US Classification:

435162, 435 71

Abstract:

Ethanol and other liquid products produced by contacting carbon monoxide (CO) and/or a mixture of CO(carbon dioxide) and H(hydrogen) with a microorganism in a bioreactor are separated using a combination of distillation and vapor permeation membranes. The bioreactor passes an effluent with an ethanol concentration of 1 to 6 wt % to a distillation column that produces an overhead vapor stream enriched in ethanol. A series of vapor permeation membranes retain ethanol as retentate and produce a 99 wt % or higher ethanol product. Ethanol depleted permeate streams flow back to the column and the bioreactor. Coupling a bioreactor with distillation and pervaporation efficiently and economically separates ethanol when present at low concentration in an aqueous fermentation broth. The separation arrangement may also include a flash zone ahead of the distillation column to raise the concentration of the ethanol in the input stream to the distillation column.
