A liquid-level sensing instrument for determining the level of a liquid in a container or vessel such as a laboratory tube in a rack or a well in a well plate with the container having an acoustically transparent top opening to direct ultrasonic signals to the liquid surface and receive reflected signals where the transceiver sensor instrument is constructed with a piezoelectric focusing sensor that has a concave focusing surface for focusing ultrasonic signals through the opening to the liquid surface in a selected container particularly a container in a group of containers and receiving reflected signals for processing.

A laboratory tube presentation unit for removal of a selected laboratory tube in a tube rack having multiple rows of laboratory tubes by raising the row of tubes in which the selected tube is located, the rack having tube wells and a rectangular bottom with a hole in each well, the unit including a selector assembly having a displaceable actuator assembly with a row of lift pins that are alignable under a select row of holes in the tube wells that correspond to a row of tubes having the selected tube in the tube rack seated on the top deck, the actuator assembly carriage having further an actuator with a manual transport shift and a lift mechanism that raises the row of lift pins under the select row of holes in the tube wells having the particular tube to be removed.

Laboratory tube presentation apparatus for raising a row of tubes contained in a rack of tubes

Automated laboratory apparatus for determining the volume of liquid samples contained in the cavities of laboratory sample collectors, such as well trays or tube racks, the apparatus having an ultrasonic height measuring instrument and a processor for calculating the volume of liquid in a particular sample container from the measured height, the apparatus also having a robotic displacement mechanism that selectively positions an ultrasonic height measuring sensor above a select sample container in the well tray or tube rack for measuring the height of liquid in the container, comparing the measured height to the height of the bottom of an empty container and calculating the volume of liquid in that container.

A compact disk duplication system with a compact disk drive with an extendible disk tray for copying data onto a batch of compact disks, the disk duplication system having a disk transport unit with an XYZ transport mechanism, the transport unit having a deck, a frame and a housing, the transport mechanism including a carriage displaceable from side to side relative to the deck, an elevator device carried by the carriage having an elevator cage displaceable up and down relative to the deck, and a tram device having a cross beam on the elevator cage with a tram having a disk pickup mechanism displaceable fore and aft relative to the deck with the displacements of the carriage, elevator cage and tram being controlled for automatic operation by controlled drive mechanisms.

Programmable compact disk duplication system with XYZ transport mechanism

A disk copying and dispensing apparatus including a disk processing module installable in a host device such as a disk vending machine, the module having a frame containing a displaceable carriage mechanism with a disk pick-up head, at least one disk recorder with an extendible tray for receiving or discharging a disk, a disk label printer and at least one disk parking tray with one embodiment having an actuatable disk dispensing chute, the disk carriage being movable from one device to another under control of a controller, in accordance with a programmed sequence of a processor.

Disk process and transport mechanism for host machines

An autoload disk copier system and disk printer transport system for recordable disks, the copier system having a copier unit with a housing containing a disk drive with an extendable disk tray, a disk carrier for supporting a stack of disks over the tray, a disk separator mechanism for selectively separating a disk from the stack displacing it to a tray, a disk retrieve mechanism for retrieving a disk from the tray and depositing it in a collector for good and bad disks, and, an electronic control means for controlling the sequence of operations of loading, disk read/write, unloading and depositing disks during the automatic process of recording data on recordable disks. The disk printer transport system combines a disk retrieve mechanism and electronic control means similar to that used in the autoload disk copier system with a retractable platform, a second disk retrieve mechanism, and a disk printer, the first disk retrieve mechanism for retrieving the disk after the completion of the copy operation and depositing the disk on the retractable platform for transport to the second disk retrieve mechanism, the second disk retrieve mechanism transporting the disk from the retractable platform to the disk printer for printing.
