Abstract: This pump for refrigerating systems, in particular for 
aeronautical applications, comprises a pump body (2) 
accommodating an impeller (4,16) rotatable about a main axis 
(3); the impeller is substantially disk-shaped and has, on 
at least one of its faces, a plurality of radial blades (5) 
arranged along a circular crown which is concentric to the 
main axis. The radial blades are accommodated in an annular 
duct (6,15,17,18) which extends in the pump body 
concentrically to the main axis and is axially delimited, on 
one side, by the blade bearing face of the impeller; the 
annular duct has an intake port (7) and a delivery port (8) 
which are angularly spaced with respect to the main axis 
for the inflow and outflow of a fluid and is closed in an 
axial direction at least in the region not affected by the 
ports, so that when the impeller rotates the fluid advances 
along the annular duct from the intake port to the delivery 
port forming vortices about the circumference defined by the 
annular duct.

Title: Container closure
IPC: B65D43/02
Filed: 1989-04-11
Abstract: A closure 9 for the open mouth 2 of a container 
includes a main body 8 and sealing means which extends 
around the periphery of the main body. The sealing 
means has a sealing edge 17 which is adapted to engage a 
sealing surface formed on the container, and a 
resiliently flexible web 16 which connects the sealing 
edge to the main body. The web is movable between a 
relaxed condition (Figure 1), in which the diameter of 
the sealing edge 17 is at a maximum, and a sealing 
condition (Figure 13), in which the diameter of the 
sealing edge 17 is less than maximum. When the closure 
operatively closes the opening 2 in the container the 
web 16 is moved to the sealing condition, and the 
resilience of the web material serves to press the 
sealing edge 17 against the sealing surface 1. 
Preferably the web 16 in its relaxed condition has a 
frusto-conical form which diverges upwardly and the 
sealing edge 17 is formed on the upper and outer edge of 
the web 16.

Patent EP-0354040-A3 (EP)
Title: Membranes prepared from blends of polybenzimidazole with polyarylates
IPC: C08L67/00
Filed: 1989-08-03
Abstract: This membrane exhibits enhanced properties over membranes prepared 
solely from either a polyarylate or a polybenzimidazole polymer. 
The addition of the polyarylate to the polybenzimidazole membrane 
allows the composition to be more thermally processable and less 
susceptible to moisture. The presence of the polybenzimidazole 
renders the polyarylate less reactive to solvents and increases 
its thermal stability. In addition, it has been surprisingly 
found that membranes prepared from the polybenzimidazole 
polyarylate blends show high regeneration capacity while 
retaining good flux ranges. The membranes prepared by this 
process exhibit good separation characteristics and provide an 
improved membrane with enhanced qualities over prior art 
membranes.

Title: Enzyme quantitation wicking assay
IPC: G01N33/558
Filed: 1989-12-28
Abstract: Diagnostic assays are provided comprising complementary enzyme fragments of  beta -galactosidase, where one of the fragments is bound to a support and the other fragment is conjugated to an immunologically cross-reactive epitope of the analyte or complementary to an analyte receptor. One can achieve a determination of ligand, by providing for competition between the ligand analyte and the conjugate for receptor, where binding to the receptor allows for discrimination between complexed enzyme fragment conjugate and uncomplexed enzyme fragment conjugate. The assay medium is then allowed to wick onto a support to which the complementary fragment is substantially uniformly bound in the detection region. The support is then developed, where color formation from the substrate in the detection region is used as a measure of the presence of analyte in the sample.

capacitor and a switching transistor. The memory has
two memory blocks each of which has memory cells
arranged in rows and columns, word lines, bit lines, a
plate line, sense amplifiers and reference voltage
generators. The memory includes a plate line voltage
control circuit which impresses supply voltage to the
plate line of one memory block and ground potential to
the plate line of the other memory block during a
transition period preceding to read or write operation
and then connects the two plate lines to thereby keep
the connected plate lines at an intermediate voltage
between supply voltage and ground potential. To retard
fatigue of the ferroelectric material by repeated
polarization in positive and negative directions, the
memory can optionally be operated in a volatile mode.
