Abstract: Methods and apparatus for use in quantifying 
components in a liquid sample, for example, white blood 
cells in blood. The invention provides a microscope slide 
for such use having at least one adhesive matrix, which is 
soluble in the liquid sample having components to be 
quantified, affixed to the operative face of the slide, 
and a plurality of substantially spherical beads of 
uniform diameter made of a substantially non-compressible 
material located within the adhesive matrix. A counting 
chamber is provided when a cover slip is provided with the 
slide. The invention further provides a stirring rod for 
use in quantifying components in a liquid sample having an 
adhesive matrix over one end portion, the adhesive matrix 
being analogous to the adhesive matrix on the microscope 
slide described above. The adhesive matrix or matrix can 
consist of a solid residue of dried liquid, and the liquid 
can be a hemolysing solution if the equipment is to be 
used for counting white blood cells. A standard 
microscope slide is provided by the invention when the 
adhesive matrix made of a solid residue of dried 
hemolysing solution, also contains a known number of 
control particles, treated so as not to lyse in the 
presence of the hemolysing solution and shaped and sized 
so as to stimulate human white blood cells. Methods for 
preparing this apparatus, using mixtures of adhesive 
liquids and beads, are also provided. Furthermore, 
methods of quantifying components in liquid samples using 
the apparatus described above are provided. Generally, 
the methods consist of either placing a liquid sample on 
the adhesive matrix of the microscope slide and mixing it 
so that the matrix dissolves in the sample, or placing a 
liquid sample on an unprepared microscope slide and 
stirring it with the stirring rod having the adhesive 
 
 
matrix over one tip so that at least a portion of the 
adhesive matrix dissolves therein. A cover slip is then 
placed over the sample so that the cover slip rests on the 
beads and is spaced from the slide by a known distance 
determined by the diameter of the beads. The counting 
chamber provided thereby is placed under a microscope and 
the components in a known volume of sample are counted, 
wherein the known volume is determined by measuring the 
viewing area of the microscope and multiplying the viewing 
area by the distance between the slide and cover slip as 
determined by the diameter of the beads.

Abstract: The method of surface-treating dry-powdered 
phosphor particles for use in manufacturing a luminescent 
viewing screen (22) for a CRT (10), to control triboelectric 
charge characteristics of the phosphor particles, includes the steps

Title: Reactor and method for production of carbon black with broad particle size distribution
IPC: C09C1/50
Filed: 1989-12-13
Abstract: A reactor (10) and method for producing carbon black in an 
axial flow carbon black reactor results in carbon black with a 
relatively broad particle size distribution and a heterogeneity 
index of greater than 1.55 and less than or equal to about 2.0. 
The reactor includes a combustion chamber (30), a choke, and an exit 
chamber (54), wherein the ratio of the cross-sectional flow area of 
the combustion chamber to the cross-sectional flow area of the 
choke is less than or equal to about 6.9, and the ratio of the 
cross-sectional flow area of the exit chamber to the cross-­
sectional flow area of the choke is less than or equal to about 3.5. 
The cross-sectional flow area of the choke section is preferably

reaction mixture through the reactor is controlled so that the 
linear velocity of the reaction mixture through the reactor is less 
than 1200 feet per second and preferably less than 1000 feet per 
second. The axial flow allows for the introduction of greater 
amounts of feedstock hydrocarbon into the flow of hot gas,

Title: Method and apparatus for testing three state drivers
IPC: G01R31/28
Filed: 1989-03-14
Abstract: In an integrated circuit chip (10) utilizing CMOS technol­
ogy, an embedded data bus (11) is driven by embedded three 
state drivers (12-15), and the bus is in turn connected to 
provide a drive signal to embedded receivers and similar 
logic devices. An embedded threshold detector (19) is 
provided to detect the occurrence of any invalid data 
signal (i.e. a non-"0" or a non-"1" signal level) on the 
data bus. The threshold detector's output signal is 
connected to off chip terminal means, to thereby enable 
off chip monitoring of the bus signal. The threshold 
detector's output signal is also ANDed with the bus sig­
nal, to thereby prevent the application of a potentially 
destructive invalid bus signal to the receivers and the 
like. Terminator circuit means provides a known invalid 
signal state on the bus when the bus is in its high imped­
ance state due to all of the three state drivers being 
disabled.

Abstract: Disclosed herein is a method of producing a single 
crystal of a high-pressure phase material having a 
pressure region of at least 1000 atm. in an equilibrium 
state at 25°C. This method is characterized in that a 
plurality of single-crystalline plates (3, 16) of the 
high-pressure phase material, being so formed that crystal 
orientations thereof are substantially equal to each 
other, are arranged so that single major surfaces (3a) 
thereof are substantially flush with each other and 
crystal orientations thereof are substantially along the 
same direction to define a substrate (1) for serving as a 
core for vapor-phase growth, and a single-crystalline 
layer (4) of the high-pressure phase material is formed on 
the substrate (2) by a vapor-phase synthesis process. 
According to the inventive method, a single-crystalline 
layer (4) of the high-pressure phase material is 
integrally formed on the major surfaces (3a) of the 
plurality of single-crystalline plates (3, 16) of the 
high-pressure phase material whose major surfaces (3a) are 
substantially flush with each other. Thus, it is possible 
to easily obtain a homogeneous and large-sized single 
crystal of the high-pressure phase material having a large 
area.

Abstract: This relates to laminated preforms, the method 
of forming such preforms and products which may be bene­
ficially formed utilizing such preforms. Most particularly, 
this relates to a preform (80) which has formed as part of the 
injection molding thereof two layers of barrier material (68,70) 
which are disposed within two layers of thermoplastic 
resin (58,60) and having received therebetween a solid core of 
thermoplastic resin. The specific method of forming the 
preform permits the barrier material layers to be of a 
greatly reduced thickness as compared to such layer thick­
nesses permissible in the past, with the result that the 
barrier material layers in the blow molded articles are of 
a thickness recognized to be acceptable for the barrier 
function. The barrier material layers may be selectively 
terminated along the length of the preform so as to 
permit portions of the resultant blow molded article to be 
removed and reused.

Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.
