Patent EP-0347297-A3 (EP)
IPC: B01D61/12
Filed: 1989-06-12
Abstract: A domestic reverse osmosis water purification 
system utilizing few parts in the controller valve 
mechanism enhances reliability and economic 
feasibility. All surfaces of the controller valve 
mechanism in contact with water are non-metallic 
and are constructed of FDA approved materials. In 
addition to its normal function of metering the 
reject water flow, the controller valve mechanism 
allows the homeowner to easily rinse the reverse 
osmosis membrane and conserves water by 
automatically stopping influent water flow when the 
product storage tank is full.

Title: Azlactone graft copolymers
IPC: C08L101/00
Filed: 1990-04-09
Abstract: Graft copolymers and processes for the 
preparation thereof are provided. The copolymers comprise 
a base polymer having grafted thereto a monomeric 
2-alkenyl azlactone. The surface properties of the graft 
copolymers can be modified by binding thereto nucleophilic 
reagents comprising further functional groups with desired 
properties. Further, the amount of azlactone available at 
the surface of a graft copolymer for binding to such 
nucleophilic reagents can be controlled by selecting a 
surface against which the graft copolymer is formed. The 
graft copolymers exhibit desirable thermoplastic, melt 
flow, and adhesion properties and are particularly useful 
for immobilizing proteins. Methods of immunoassay based 
on the immobilization of proteins are also disclosed. 
Another utility of the graft copolymers involves the 
compatibilizing of immiscible polymer blends.

Title: Drainage scoop wheel.
Inventor: DRECHSLE ROLAND
IPC: B01D21/00
Filed: 1993-10-15
Abstract: The invention relates to a drainage scoop wheel for recovering fine sand from the washing water of gravel washing installations. It is based on the object of reducing the quantity of clean water and waste water in gravel and sand processing and of at the same time improving the efficiency of the fine-sand recovery and the quality of the fine sand. According to the invention, this object is achieved in that channels (6) are arranged inside the scoop wheel tub (1), on the tub wall opposite the inlet (4) on both sides of the wheel (2), in that the channels (6) lead, at their upper end, via one or more passage opening(s) (17) in the tub wall, to one or more water collection reservoir(s) (8, 16) in such a manner that the same liquid level results in these water collection reservoirs (8, 16) as in the tub (1), the water collection reservoirs (8, 16) being connected to at least one suction pump (7) which pumps or pump the water flowing through the channels (6) out of the tub (1) as recycling water back into a gravel washing installation arranged upstream of the scoop wheel, and in that the channels (6) have intake openings (18) at their lower end, at a sufficient distance from the waste water layer (15). Seen from the intake openings (18), the channels (6) run obliquely upwards towards the side of the outlet (5). <IMAGE>

Abstract: A data memory system has a hierarchic disk array (11) of multiple
disks (12), a disk array controller (14) for coordinating data transfer to and from
the disks (12), and a RAID management system (16) for mapping two different
RAID areas onto the disks (12). The RAID management system (16) stores data
in one of the RAID areas according to mirror redundancy, and stores data in the
other RAID area according to parity redundancy. The RAID management system
(16) then shifts or migrates data between the mirror and parity RAID areas on
the disks (12) in accordance with a predefined performance protocol, such as
data access recency or access frequency. The data memory system also
includes a memory map store (21) embodied as a non-volatile RAM. The
memory map store (21) provides persistent storage of the virtual mapping
information used by the RAID management system (16) to map the first and
second RAID areas onto the disks (12) within the disk array (11). The RAID
management system (16) updates the memory map store (21) with new
mapping information each time data is migrated between mirror and parity RAID
areas.
