A heat transfer and conditioning unit includes a casing overlying a fire chamber. An exhaust conduit is disposed within said casing inwardly of its walls having an inlet to receive heated exhaust gases and an outlet adapted to communicate with a flue to atmosphere. The exhaust conduit includes a series of pairs of opposed parallel laterally elongated plates. Inwardly directed opposed V-formed plates interconnect adjacent plates to define a series of longitudinally spaced laterally elongated venturi passages along the length of said exhaust conduit. Said venturi passages effectively slow down the movement of the products of combustion through the exhaust conduit for increased quantities of heat transfer to the walls thereof. The walls of said exhaust conduit are spaced from the casing to define an independent fresh air heating chamber along the walls of said casing and exhaust conduit for the conductive transfer of heat to the forced fresh air passing therethrough.

摘要:
An automated analyzer for performing multiple diagnostic assays simultaneously includes multiple stations, or modules, in which discrete aspects of the assay are performed on fluid samples contained in reaction receptacles. The analyzer includes stations for automatically preparing a specimen sample, incubating the sample at prescribed temperatures for prescribed periods, performing an analyte isolation procedure, and ascertaining the presence of a target analyte. An automated receptacle transporting system moves the reaction receptacles from one station to the next. The analyzer further includes devices for carrying a plurality of specimen tubes and disposable pipette tips in a machine-accessible manner, a device for agitating containers of target capture reagents comprising suspensions of solid support material and for presenting the containers for machine access thereto, and a device for holding containers of reagents in a temperature controlled environment and presenting the containers for machine access thereto. A method for performing an automated diagnostic assay includes an automated process for isolating and amplifying a target analyte. The process is performed by automatically moving each of a plurality of reaction receptacles containing a solid support material and a fluid sample between stations for incubating the contents of the reaction receptacle and for separating the target analyte bound to the solid support from the fluid sample. An amplification reagent is added to the separated analyte after the analyte separation step and before a final incubation step.
摘要:
An automated process performed in an analyzer for detecting the presence of a target nucleic acid in a sample. The process includes separating the target nucleic acid from other material present in the sample, performing an amplification reaction to produce an amplification product indicative of the presence of the target nucleic acid in the sample, and detecting the amplification product. The amplification reaction can be performed in an open receptacle vessel, such as a test tube.
摘要:
An automated process for detecting the presence of a target nucleic acid in a sample. The process is performed in a stand-alone unit and includes separating the target nucleic acid from other material present in the sample, engaging a robotic pipettor to combine the separated target nucleic acid and reagents for performing an amplification reaction, and performing an amplification reaction. A product of the amplification reaction is detected as an indication of the presence of the target nucleic acid in the sample.

The present invention is directed to a laser communication transmitter and receiver for wireless optical communication. The laser communication transmitter uses a small diameter so correspondingly divergent beam to provide improved bit error rates. A laser communication receiver includes a diffractive optical element to permit detectors at different spatial locations to detect different wavelengths of the optical signal. An immersion lens may be employed to focus the optical signal to a spot size smaller than the photoactive area of the detector.

An automated analyzer for performing multiple diagnostic assays simultaneously includes multiple stations, or modules, in which discrete aspects of the assay are performed on fluid samples contained in reaction receptacles. The analyzer includes stations for automatically preparing a specimen sample, incubating the sample at prescribed temperatures for prescribed periods, preforming in analyte isolation procedure, and ascertaining the presence of a target analyte. An automated receptacle transporting system moves the reaction receptacles from one station to the next. The analyzer further includes devices for carrying a plurality of specimen tubes and disposable pipette tips in a machine-accessible manner, a device for agitating containers of target capture reagents comprising suspensions of solid support material and for presenting the containers for machine access thereto, and a device for holding containers of reagents in a temperature controlled environment and presenting the containers for machine access thereto.

摘要:
A reaction receptacle apparatus includes one or more individual receptacles for containing chemical or biological substances. The one or more receptacles are arranged to be engaged by tubular elements of a substance transfer device for transferring substances into or out of the individual receptacles. Multiple receptacles are coupled to one another by a connecting rib structure that defines straight shoulders along opposite sides of the reaction receptacle apparatus, and the shoulders support the apparatus within reaction receptacle apparatus carrying structures. A contact-limiting element holding structure for holding contact-limiting elements, such as protective tips for tubular elements, is associated with each individual receptacle and holds a contact-limiting element in an operative orientation so as to be operatively engageable by the tubular element of the substance transfer device. A receptacle apparatus manipulating structure permits the reaction receptacle apparatus to be moved from one location to another by a robotic manipulating device, and an information panel presents a surface on which human and/or machine readable information may be placed.

A container closure includes a shell attachable to a container around a container opening thereof. The shell has a shell opening in fluid communication with the container opening when the shell is attached to the container. A tip is received on the shell movable between a closed position sealing the shell opening and an open position. A cover is releasably attached to the shell in a manner indicative of the tip being positioned in the closed position when the cover is attached to the shell. Both the shell and the cover may be provided with tamper-evident bands. The present invention is particularly well adapted to be formed as a push-pull container closure for sports bottles and the like.
