Abstract:
A computer-implemented method of handling a container includes performing a first scan of the container. The container includes objects therein. The scan includes irradiating the container with polychromatic x-rays with a first x-ray scanning system at a first geographic location and generating a first scan record using a processing device. The method also includes moving the container from the first geographic location to a second geographic location. The method further includes performing a second scan of the container including irradiating the container with polychromatic x-rays with a second x-ray scanning system at the second geographic location and generating a second scan record using a processing device. The method also includes comparing the first scan record and the second scan record. The method further includes determining the second scan record is substantially indistinguishable or distinguishable from the first scan record.
Abstract:
Provided is an X-ray inspection device having a pair of conveyor frames that is disposed symmetrically with respect to a center line as an axis along a substrate conveying direction, and clamps a printed substrate in a substrate width direction. A substrate conveying mechanism conveys in an X axis direction the printed substrate supported by the conveyor frames. A distance adjustment mechanism drives the pair of conveyor frames so that the conveyor frames approach or depart from each other in the Y axis direction, thereby adjusting the width dimension of a printed substrate that can be conveyed by the substrate conveying mechanism disposed on each of the conveyor frames.

The invention relates to a device (10; 10a;10b; 10c; 50) for checking pharmaceutical products (1), in particular hard gelatin capsules, by means of at least one radiation source (30; 60) preferably embodied as an X-ray source, and a conveying device which conveys the products (1) in a clocked manner in a radiation area (31) of the radiation source (30; 60). The radiation emitted by the radiation source (30; 60) penetrating the products (1) preferably perpendicular to the longitudinal axes thereof (2), and the radiation is captured on the side of the products (1) opposite the radiation source (30) by means of at least one sensor element (35) which is coupled to an evaluation device (36). The invention is characterized in that the conveyor device is embodied as a conveyor wheel (15; 15a; 51) which can rotate in a stepped manner about an axis (12; 52), and the products (1) are arranged, while being conveyed in the radiation area (31), in receiving areas (28; 37; 56) of the conveyor wheel (15; 5a; 51).
Abstract:
The invention relates to a changer mechanism for individual measurement of radioactive samples in a gamma counter. The changer mechanism comprises an identifying element for identifying sample containers of different sizes and a transferring device for transferring the sample containers to the measuring unit for measuring, and back therefrom after measuring. According to the invention, the changer mechanism comprises a lifting device having a grip unit for lifting and transferring the sample from the transfer unit to the measuring unit. The grip unit is provided with grip elements for transferring samples of different sizes based on the information obtained from the identifying unit.
Abstract:
An arrangement for measuring radioactivity of an eluate flow with a flow-through detector arrangement, including at least one radioactivity detector, and a valve arrangement by way of which the eluate flow can be redirected through the at least one radioactivity detector where the radioactivity of the eluate is measurable in a stationary manner.
Abstract:
A system for the measurement of radioactivity of a number of radioactive samples by a radiation detector which will be affected by radiation from a number of other sources having predetermined locations in addition to the sample being measured consists of first measuring the values of activity measured by the detector when a standard radiation source of known activity is placed in the detector and in each of the predetermined locations to determine the effect of the other sources on the measurements of the detector, storing the values thus determined and thereafter compensating the values of radioactivity of each sample measured by the detector with the stored values to obtain the actual values of radioactivity of the samples.
Abstract:
Improved means for expelling sample carriers which have been automatically elevated to the sample measuring chamber of a radiation measuring apparatus, from the measuring chamber. The means are collapsible within the instrument housing, as to remain therein as a sample carrier is elevated toward the measuring chamber. Additionally, the means comprise a disposable contamination member which can be removed and discarded in the event of contamination.
Abstract:
A mechanism for centering a movable member within an elongated passageway of variable width, such as for use in an article transport system of a benchtop scintillation detector or other laboratory sample processor. The centering is performed by a plurality of outwardly bowed guide elements attached to the movable member, arranged around the periphery of the movable member, and oriented generally along the axis of travel of the movable member. In the particular embodiment herein, the guide elements are maintained in bowed position by one or more biasing means housed within the movable member. The bowing of the guide elements urges the movable member toward the center of the passageway at all times, regardless of the transverse dimension of the passageway, and regardless of the presence of gaps in the passageway.
Abstract:
A gamma activity counter apparatus for use in automated radioimmunoassay systems including a scintillator counter which has two scintillator crystal-photomultiplier tube assemblies removably contained within a lead radiation shield. Each crystal has formed in it a sample receiving zone, each zone communicating with vertical bores formed in the radiation shield, so that a lifting means can lift sample carriers disposed beneath and in alignment with the sample receiving zones into the zones for gamma activity counting. The lift means is so designed that for each counting period, a pair of sample carriers, separated from each other by an even number of sample carrier spaces, is lifted into the sample receiving zones for simultaneous counting, the sample carriers being contained in holders that are continually advanced over the lift means in increments of two sample carrier spaces per increment. The sample carriers, arranged in a specified order in the holders, are counted out of order and this counting data is fed to a logic means in which the data is re-ordered, and this properly re-ordered data is fed to a data printing means.
