Abstract: Abstract Heinrich Amelung GmbH, Lehbrinksweg 59, 4920 Lemgo 1 1.    Device for photometrically determining the coagulation behavior of blood, blood plasma or the like.   2.1.  A known device for measuring light waves of blood or blood plasma has a receptacle seat which is provided with one or more receptacle holders into each of which a receptacle filled with an appropriate sample can be inserted from the top.  Until now it has been necessary, after the measuring of the light waves has been completed, to take the respective receptacle out of the receptacle holder from the top.  A photometric measurement cannot take place during this time  Thus, it is the object of the invention to shorten the chronological sequence of a photometric measurement.   2.2.  To accomplish this, the receptacle holder (3) is provided with an opening on its bottom side which can lead into a shaft (6).  In addition, the receptacle holder (3) has a leaf spring (8) with which the sample to be measured can be held in the receptacle holder (3).   2.3.  This construction makes it possible to push the receptacle in which the measurement has been completed downward with a new receptacle to be inserted in the receptacle holder.  It is no longer necessary to remove it through the top, so that the removal time is omitted and the chronological photometric measurement is considerably shortened.   3.    Figure 1.

IPC: G01N33/58
Filed: 1992-05-26
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.

Abstract: An antenna handling mechanism incorporated in a portable radio communication apparatus includes an antenna which can be pulled out of the casing of the apparatus.  When the antenna is received in the casing, the lower end thereof is locked by a latch mechanism disposed in the casing.  In this condition, as the tip of the antenna is pressed, the latch mechanism unlocks the lower end of the antenna and, at the same time, pushes the antenna out of the top of the casing. When the antenna is pressed into the casing and reaches a predetermined position, the latch mechanism again locks the lower end of the antenna.
