Abstract: A memory system includes a memory array having a plurality of memory cells; and a controller coupled to the memory array, the controller configured to: designate a storage mode for a target set of memory cells based on valid data in a source block, wherein the target set of memory cells are configured with a capacity to store up to a maximum number of bits per cell, and the storage mode is for dynamically configuring the target set of memory cells in as cache memory that stores a number of bits less per cell than the corresponding maximum capacity.

Abstract: A system for producing a finished printed product exhibiting print specific conditions by automatically translating print or job specific conditions to an appropriate set of machine specific functions associated with printing press machines and auxiliaries so as to manipulate and obtain a final desired set of print specific conditions. The system includes software control means for controlling the printing press machines and auxiliaries, and an input device allowing a pressman to enter print specific data into the system.

Abstract: The cyclone degritter particularly suited for household use for receiving, degritting and discharging a water feed flow. The cyclone degritter comprises a pressurized housing containing a cyclonic degritter cartridge with a plurality of small hydro-cyclones arranged within a shell for collecting grit and an overflow vessel for directing clarified liquid to the housing overflow connection. In one form there is a bleed line from the top region of the shell or grit pot to the overflow for providing substantially improved recovery efficiency. In another form the cyclone degritter is provided with primary and secondary cyclone degritters with the primary set being used under conditions of low water flow while both primary and secondary sets are used for increased water flow.

Abstract: The present invention provides a novel apparatus for culturing mammalian cells, whereby a plastic housing encasing a double membrane bag or bags supplies nutrients and oxygen to mammalian cells for propagation thereof. The double membrane bag contains a first bag formed of a microfiltration or ultrafiltration membrane disposed within a second membrane bag formed of a liquid impermeable, gas permeable membrane. This apparatus has a first chamber containing oxygen, a second chamber containing cells and a third chamber containing nutrients.

Abstract: In a membrane separation device means for mounting a semi-permeable membrane separation unit on the sidewall of a casing including a plug member and releasable interlocking means for interconnecting the plug and separation unit to the sidewall with the plug member including permeate outlet means for discharging permeate from the separation unit.
