摘要:
It is described a conveyor of specimen containers (9) supported by carriers (8) in laboratory automation systems comprising at least one analyzer (10, 50, 60). Said conveyor comprising a main transport unit (2), at least one spur transport unit (4-5, 7) allowing the positioning of the specimen container (9) inside said at least one analyzer (10, 50, 60) without removing said specimen container (9) from its carrier (8).
摘要:
A transfer and positioning apparatus (10) includes a positioning assembly (100) located between the tracks (12 and 14) of a dual lane conveyor (16) and upstream of a lane changer (22).
摘要:
A transfer apparatus (10) includes a shuttle (60) depending from an overhead (58) support with a pair of arms (68, 70) for receiving and shifting a specimen carrier (18) from one conveyor (12) to a second conveyor (14) of a dual-conveyor track. The shuttle is operable to retain a specimen carrier along either the first or second conveyor and to release a specimen carrier along either the first or second conveyor. Sensors (40, 42, 48, 50) are located to detect the presence of a specimen carrier at each of the retention locations, and to confirm the release of a specimen carrier from the shuttle along each of the conveyors. A drive motor (78) for moving the shuttle between the retention and release positions is electrically connected to a command module with a processor, for receiving instructions as to the position of the shuttle. The sensors are also connected to the processor to transmit detection data to the processor. A queue is positioned upstream of the shuttle and is electrically connected to the processor. The queue includes retractable shafts, sensors and scanners for selectively retaining, detecting and scanning identification data from a specimen carrier on either conveyor upstream of the shuttle, and transmitting the information to the processor.

摘要:
A method for generating a vortex-like mixing action within a liquid held in a container by causing the container to move back and forth in a constant sinusoidal pattern at high speeds. Momentum forces acting upon the liquid solution cause it to generate an internal mixing motion of the liquid solution without the aid of extraneous mixing members.
摘要:
Es wird eine Vorrichtung zum Bewegen von mindestens einer Einheit entlang einer Bewegungsbahn vorgeschlagen. Die Vorrichtung umfasst ein Gehäuse(1) mit einer parallel zur Bewegungsbahn verlaufenden Öffnung(10), eine Führungsschiene(5) für die Einheit(6) und mindestens eine Antriebsvorrichtung(7), die mit der Einheit verbunden ist. Zum Abdecken der Bewegungsbahn der Einheit ist ein flexibles Element(8) vorgesehen, welches in den Endbereichen der Bewegungsbahn am Gehäuse(1) festgelegt ist und die Einheit teilweise so umgibt, dass die Einheit(6) durch die Öffnung(10) zugänglich ist Dadurch, dass die Einheit entlang der Führungsschiene als auch entlang dem Element bewegbar ist, wird in vorteilhafter Weise der Innenraum des Gehäuses gegen die Umgebung immer abschlossen.
摘要:
Liquid dispensing apparatus comprises a support member (11) which supports a movably mounted dispensing member (17). The support member (11) is movable between first and second positions. A single drive system (7,8,16,18,20) causes the dispensing member (17) to move relative to the support member (11) to a number of dispense positions while the support member is in its first position and causes the support member to move to the second position.
