IPC: G01N30/96
Filed: 1992-09-23
Abstract: Improved capillary electrophoresis apparatus of the type that generally includes a capillary tube, the capillary tube having a sample inlet end and an outlet end, a first electrode in electrical communication with the inlet end of the capillary tube, a sec-ond electrode in electrical communication with the outlet end of the capillary tube and a high voltage power supply in electrical communication with the first and second electrodes. The improvement is to connect a miniature Ion Chromatography membrane suppressor to the outlet end of the capillary tube, to connect a conductivity detector to the membrane suppressor and to place the second electrode in the regenerant compartment of the membrane suppressor. The method embodiment of the invention for anion analysis includes the steps of: (a) separating anions of interest by capillary electrophoresis in a buffer solution; (b) exchanging cations of the buffer for regenerant cations using an ion chromatography membrane suppressor to reduce the electrical conductiv-ity of the buffer to produce a suppressed buffer; and (c) measuring the electrical conductivity of the suppressed buffer to deter-mine the separated anions. Similarly, the method embodiment of the invention for cation analysis includes the steps of: (a) sepa-rating cations of interest by capillary electrophoresis in a buffer solution; (b) exchanging anions of the buffer for regenerant anions using a stationary means for exchanging anions thereby reducing the electrical conductivity of the buffer to produce a sup-pressed buffer; and (c) measuring the electrical conductivity of the suppressed buffer to determine the separated cations.

Abstract: A train of at least two track guided cars with single axial bogies has an orientation control for the single axial bogies which essentially guarantees an exact orientation of the single axle bogies perpendicular to the longitudinal axis of the track during all traveling conditions. A substantially inelastic axle steering arrangement is combined with an elastic automatic axle orienting arrangement (self-orientation elasticity e), which provides for an automatic orienting as well as controlled steering of the single axle bogie. This combined bogie orientation control will automatically correct the incorrect bogie orientation angles which are produced with inelastically linked bogie steering at the entry into and the exit from a curve.

Abstract: A blind spline broaching machine for machining splines as well as sprockets, keyways, gears, cams and contours on workpieces, such as shafts. The blind spline broaching machine of the preferred embodiment has dual rams reciprocable relative to a rotary dial.  The rams hold a corresponding pair of workpieces, while the rotary dial supports one or more broaching tools. The rotary dial is rotatable to index the workpieces to and from the rams. The blind spline broaching machine also incorporates a part moving unit on its periphery, which enables the use of a single loading/unloading station at which workpieces are alternately loaded onto and unloaded from the rotary table.  Because the workpieces are loaded and unloaded from the same location on the periphery of the blind spline broaching machine, the side of the blind spline broaching machine opposite the loading/unloading station remains open to permit ready access to the tooling and the interior structure of the blind spline broaching machine.  In addition, only one conveyor system is required to transport workpieces to and from the blind spline broaching machine.  As a result, the complexity of and the floor space required for the blind spline broaching machine is substantially reduced.

Abstract: A rotary disk valve has a valve body provided with an annular valve seat section defining a central opening to be removably closed by a valve disk. The valve disk is supported by a drive assembly which includes a drive shaft mounted on the valve body and supporting a drive link for rotation with the shaft. The link mounts a valve disk support shaft which extends slidably through a slot in a bracket secured to the valve disk. The bracket mounts a guide cam follower pin arranged to engage a guide cam secured to the valve body. The arrangement of drive shaft, valve disk support shaft, bracket slot and guide cam and follower is such that rotation of the drive shaft through 180° in one direction first moves the valve disk from open position disposed in a plane substantially perpendicular to the plane of the central opening in the valve body to an intermediate position spaced from but parallel to the valve seat surface, and then moves the valve disk linearly into sealing engagement with the valve seat section of the valve body. Reverse rotation of the drive shaft moves the valve disk from open to closed position.

Title: Aminoalkylphosphonic acid containing ligands attached to solid supports for removal of metal ions
Inventor: BRUENING RONALD L
IPC: C01F7/02
Filed: 1992-09-14
Abstract: A method for the removal and concentration of desired ions such as Sb3+, Zr4+, Zn2+, Pu4+, Hf4+, Cu2+, Ni2+, Fe3+, Cd2+, Ag+, and Hg2+ from a multiple ion source solution which may contain larger concentrations of other undesired ions including H+ comprises bringing the source solution into contact with a compound comprising an aminoalkylphosphonic acid containing ligand covenlently bonded through an organic spacer silicon grouping to a solid inorganic support. The am-inoalkylphosphonic acid containing ligand portion(s) of the compound has an affinity for the desired ions to form a com-plex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by con-tacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired ions than does the aminoalkylphosphonic acid containing ligand portion of the compound.  The process is useful in removing desired or unwanted ions of Sb(III) from acidic waste streams, streams containing concentrated Cu(II), Ni(II), Zn(II), and Ag(I), and also the removal of Zr(IV), Pu(IV) and Hf(IV) from nitric acid solutions containing large amounts of other ions as well removal of unwanted ions from other industrial or environmental streams.

IPC: A61K47/48
Filed: 1993-01-11
Abstract: A compound comprises a target cell-specific portion, such as an antibody specific to tumour cell antigens, and an inactivat-ing portion, such as an enzyme, capable of converting a substance which in its native state is able to inhibit the effect of a cytotox-ic agent into a substance which has less effect against said cytotoxic agent.  The prolonged action of a cytotoxic agent at tumour sites is therefore possible whilst protecting normal tissues from the effects of the cytotoxic agent.

Abstract: A method which permits easy fusion of commutator risers to armature coils of an electric motor.  When there are 20 risers, for example, 10 through-holes are formed in the boss portion of the armature core of the motor, each through-hole being so sized that the back surfaces of two adjacent risers are exposed through each through-hole.          Sub-electrodes are inserted into the through-holes such that each sub-electrode supports the back side of the two risers exposed through the through-hole which receives this sub-electrode.  First and second main electrodes are so arranged that the first electrode contacts with the first riser of the first riser group exposed through the first through-hole while the second main electrode contacts the second riser of the sixth riser group exposed through the sixth through-hole.  After conducting fusing on these risers, the main electrodes are shifted into contact with the risers which are the second as counted from the risers which have just been fused, and fusion is conducted on these risers.  This operation is repeated until all the risers are fused.
