Title: Latex agglutination immunoassay in the presence of hemoglobin
Inventor: LEWIS LYNETTE A
IPC: G01N33/72
Filed: 1988-08-30
Granted: 1994-09-20
Abstract: ABSTRACT OF THE DISCLOSURE      A latex agglutination immunoassay method for determining an analyte in a blood sample in which the pH of the reaction mixture is maintained at about 8.5 or greater in order to overcome nonspecific agglutination of latex particles by hemoglobin present in the sample.  The method is particularly applicable to the determination of glycated hemoglobin, e.g., Hb Alc.  In another embodiment, native hemoglobin (Ao) can be determined based on its ability to cause agglutination of latex particles suspended in an aqueous solution having a pH of about 8 or below.

Abstract: ABSTRACT OF THE DISCLOSURE A frame for constructing pavement blocks in which plural sections each having a bottom with plural holes for draining water therethrough each have plural through holes from the top to the bottom of section walls defining the above sections, the lower sides of the holes being open and the upper ends of the holes being closed by a closure which is easily openable.  The closure can be a thin film which is integrally formed with the walls or an adhesive tape which is applied to the upper edges of the section walls.  To form the pavement blocks, concrete or mortar is poured into the sections, and after it hardens, the upper ends of the through holes are opened by removing the film or by strip-ping off the adhesive tape.  The resulting frame with con-crete or mortar therein can be used for producing a permeable pavement in which water is drained of r through the through holes.

Abstract: According to the present invention, tunnels, particularly shallow tunnels, are constructed by excavating slurry filled cross-trenches in a direction transverse to the axis of the tunnel and at regular intervals along the line or axis of the tunnel.  Prefabricated frame elements are inserted into the cross-trenches to, in essence, create the tunnel wall lateral support structure before the tunnel walls are installed.  Then the tunnel sidewalls are excavated under bentonite clay or mud slurry to form cross-slots between the previously installed support frames.  Precast concrete sidewalls or panels are inserted between the support frames.  The frames and sidewalls have interlocking tongue and groove or keyway structures so as to interfit and lock same into position.  When the sidewalls are in place, the roof of the tunnel may be either cast in place and then the soil excavated to form the actual tunnel and then the floor cast or the tunnel may be excavated down to the floor or invert level and then the floor or inverts cast and then the roof cast.

The cut-ting wheels include a plurality of cutting teeth and cutting wheel spacers maintain the cutting wheels in a spaced relationship on the shafts to prevent damaging contact between the teeth.  A comber is aligned with each cutting wheel to provide a gap between the cutting teeth and the end of the comber and is maintained in alignment to prevent damaging contact with the teeth of adjacent cutting wheels. The disposable containers are cut into first pieces between the cutting wheels of one shaft and the cutting wheels of the other shaft.  The first pieces from the first cutting section pass to a second cutting section to be cut into smaller, second pieces.  The invention also includes the method of cutting the disposable con-tainers in pieces.

Abstract: COMPARTMENT PANEL CONTROL APPARATUS FOR A MOTOR VEHICLE            Abstract of the Disclosure An integrated panel control in which both the release and pulldown mechanisms are controlled by a single operator activated switch.  Initial operator activation of the switch when the panel is closed energizes the release mechanism through a latch switch which indicates that the latch bolt and striker are mechanically coupled.  Initial operator activation of the switch when the panel is open activates the motor of the pulldown mechanism through the latch switch in initiate a pulldown of the panel.  A second activation of the switch during the pulldown aborts the pulldown sequence by reversing the pulldown motor, freeing a spring or other device to re-open the panel. A second activation of the switch after the latch bolt and striker are mechanically coupled energizes the release mechanism through the latch switch to uncouple the latch bolt from the striker, freeing a spring or other device to open the panel.

Abstract: A color display system (9) includes a cathode-ray tube (10) and yoke (30). The yoke is a self-converging type that produces an astigmatic magnetic deflection field within the tube. The cathode-ray tube has an electron gun (26) for generating and directing three electron beams (28) along paths toward a screen (22) of the tube. The electron gun includes electrodes (34,36,38,40) that comprise a beam-forming region and electrodes (44,46) that form a main focusing lens, and features electrodes (42,44) for forming a multipole lens between the beam-forming region and the main focusing lens in each of the electron beam paths. Each multipole lens is oriented to provide a correction to an associated electron beam to at least partially compensate for the effect of the astigmatic magnetic field on the associated beam. There are two multipole lens electrodes. A second of the two multipole lens electrodes (44) is connected to and combined with a main focusing lens electrode (44), and a first of the two multipole lens electrodes (42) is located between the second multipole lens electrode and the beam-forming region and faces the second multipole lens electrode.
