Title: Method of improving the demarcation and separation of cells in centrifuged blood samples
IPC: G01N33/49
Filed: 1986-10-21
Abstract: In order to produce a more well defined interface between adjacent cell layers in a centrifuged sample of anticoagulated whole blood, e.g. between the erythrocytes and the leukocytes, a material which will selectively bond one group of cells together, e.g. the erythrocytes, is added to the blood sample prior to centrifugation. The bonding material must produce a high strength bond between one group of cells, but not affect the other cell types. The material is added prior to centrifugation of the blood sample.

Abstract: A piston (151) for reciprocating, sliding motion 
within a cylindrical bore (175) in response to 
rotation of an eccentric crank about an axis that 
is normal to the cylindrical bore (175)includes 
a spherical outer surface with a plane therethrough 
of maximum diameter, that is substantially equal 
to the diameter of the cylindrical bore, upper

Abstract: Adhesives for ceramics obtained as first adhesives 
for ceramics according to the invention are excellent in 
bond properties as well as in water resistance because 
they contain first acidic compounds such as organic 
carboxylic acids in addition to silane coupling agents, 
polymerizable monomers and polymerization catalysts. 
Further, adhesives for ceramics obtained as second 
adhesives for ceramics according to the invention are 
excellent in bond properties as well as in dependability 
and water resistance because they contain metal salts in 
addition to silane coupling agents, polymerizable monomers 
and polymerization catalysts. Furthermore, adhesives for 
ceramics obtained as third adhesives for ceramics 
according to the invention are excellent in bond 
properties as well as dependability and water resistance

IPC: H01L27/10
Filed: 1987-09-24
Abstract: A memory array included with logic circuitry on an integrated circuit 
is tested by a technique that reads and writes a specified sequence of test bits into 
a given memory word before progressing to the next word. A checkerboard 
pattern of 1's and 0's is written into the physical memory locations. This 
provides for an improved worst-case test while allowing ease of implementation 
for the test circuitry. The test results from a comparator circuit may be 
compressed to provide one (or a few) test flags indicating whether the memory 
passed the test, requiring a minimal number of test pads or terminals for the chip.

Patent EP-0336770-A3 (EP)
IPC: H04M3/523
Filed: 1989-04-07
Abstract: The present invention describes a method and apparatus 
for predictive dialing in a multi-operator telephone system 
which improves the productivity of operators while 
simultaneously reduces customer "unattended" calls. These 
objectives are achieved by generating a prediction of the 
number of operators expected to be available at the end of a 
predetermined time interval in the future, as well as a 
prediction of the number of calls expected to be successfully 
completed during that time interval. The predicted number of 
calls is then weighted by an "weighting" factor which is 
controlled by variations in the percentage of unattended calls 
and variations in the average operator idle-time between 
calls. The system dynamically adjusts the number of calls 
dialed based on short term comparisons of the weighted 
predicted number of calls versus the predicted number of 
operators, and based on periodic adjustment of the weighting 
factor.
