Abstract: An automatic chemistry analyzer includes sample cups (11) circumferentially located on a sample wheel (12). Means (15,17) moves the sample cups rotationally under cycloidal action to and away from a target location (14) where a probe (27) operates vertically in relation to the sample cups and an injection cell (24). The motion is effected by a cam (17) operating with a cam follower formed by lobes (30) circumferentially located about a drive wheel (13) which houses the sample wheel or carousel (12).

Abstract: To fabricate electrically conductive probe tips by electrolytically machining a wire consisting of electrically conductive material, the wire is immersed in an electrolytically active liquid layer consisting of an electrolyte solution which is surrounded by at least one electrically insulating insulator. The immersion is done in such a way that the wire region intended for the formation of the probe tip is in contact with the electrolytically active liquid layer between a guided end and a free end of the wire, and the free end of the wire is fed into the insulator through the liquid layer. The wire region in contact with the electrolytic liquid layer then grows with a specified reduction in its cross section to form a very fine tip until the free end is separated from the guided end.

Abstract: When a received image is recorded on roll paper, and when the roll paper on which the image is recorded is cut in a standard size to output the image, the leading end portion of the received image is removed so that the image is recorded on the roll paper. If the length of the recorded image is less than a standard size length, blank space is added to the image to output the recorded image in a standard size. This permits the received image to be recorded in real time and a recorded image of an appropriate standard size to be obtained. There is thus no need for a large capacity image memory.

Abstract: The present invention relates to analytical methods for determining the composition of a material that undergoes a transition as a function of a driving variable. As applied to thermogravimetric analysis (TGA), a first preferred embodiment comprises (1) decreasing the heating rate when deviations from a baseline signal are detected; (2) establishing a minimum heating rate; (3) forcing the heating rate to a predetermined maximum whenever the rate of change of the weight change with respect to the temperature falls below a predetermined value; and (4) adjusting the heating rate according to the rate of change of the weight of the sample to track a predetermined rate of change of the weight of the sample. A second preferred embodiment comprises (1) selecting either a high-productivity or a high-resolution mode; (2) in both modes, controlling the rate of temperature increase according to a function containing an exponential term, wherein the argument of the exponential term includes the percent weight change per unit time of the sample; (3) in the high-productivity mode, choosing the function so that when the percentage weight change per minute of the sample is small, the heating rate approaches the maximum allowed heating rate, and when the percentage weight change per minute is very large, the heating rate approaches zero; (4) in the high-resolution mode, choosing the function such that the heating rate is held at almost zero during a transition.

Abstract: A method of determining free analyte level in a sample containing the analyte in free and bound portions is accomplished in sequential steps as follows. The sample is combined with a known first liquid volume containing soluble anti-analyte receptor in excess of the free analyte in the sample. The resultant mixture is incubated for a period of time sufficient to allow the binding reaction of the free analyte with the anti-analyte receptor to reach substantial completion to form a first incubation mixture. A known second liquid volume is added thereafter which contains soluble conjugate sufficient to reduce the sample proportion in the resultant mixture to no greater than 10% v/v, with the conjugate comprising a labeled analyte or labeled analog thereof, to allow the conjugate to bind with the anti-analyte receptor not bound in the first incubation mixture to form a second incubation mixture. Thereafter, separation means is introduced to the second incubation mixture which comprises a solid phase coated with immobilized binder for the anti-analyte receptor, which binder is in excess of the anti-analyte receptor to bind substantially with all of the anti-analyte receptor in the incubation mixture. The solid phase is then separated and washed from the mixture. The amount of conjugate that is bound to the solid phase is measured, and the free analyte concentration in the sample is determined.
