    摘要： There is disclosed an apparatus for controlling the temperature of discrete sample containers in analytical instrumentation. A conveyor containing discrete samples to be analyzed is located in a subcompartment within a larger enclosure. A fan is mounted in a first opening in the subcompartment to move air from the large enclosure into the subcompartment. A second opening in which a thermal energy transfer element is mounted allows the passage of the air over the thermal energy transfer element back into the larger enclosure. A temperature sensor contacts a sample container being measured to provide a control signal which is applied to a proportionally controlled power supply connected to the thermal energy transfer element.

    摘要： A CULTURE BOTTLE ASSEMBLY OF THE TYPE USED FOR CULTURING BLOOD SAMPLES. THE ASSEMBLY INCLUDES A TRAY INSERT WHICH IS DESIGNED TO HOLD A SOLID AGAR NUTRIENT MATERIAL AT A LOCATION ALONG THE AXIAL CENTERLINE OF THE BOTTLE. THE BOTTLE ALSO HOUSES A LIQUID NUTRIENT BROTH WHICH MAY BE SEPARATED FROM THE SOLID AGAR BY POSITIONING THE BOTTLE ON ITS SIDE.

    摘要： A PROCESS OF STAINING BACTERIA FIXED ON A SLIDE AND DEVICE FOR CARRYING OUT THE PROCESS. THE DEVICE IS MADE OUT OF A NON-ABSORBENT MATERIAL SUPPORTING AN ABSORBENT MATERIAL WHICH HAS BEEN TREATED WITH STAIN AND THEN DRIED. TO STIN THE BACTERIA, EITHER A DROP OF SOLVENT IS PLACED ON THE SLIDE OR SOLVENT IS DROPPED THROUGH A HOLE OR HOLES IN THE NON-ABSORBENT MATERIAL,. THE SOLVENT REDISSOLVES THE STAIN WHICH IS THEN CARRIED DOWN ONTO THE BACTERIA. THE STAIN IS KEPT ON THE BACTERIA FOR AS LONG AS IS NECESSARY TO COMPLETE STAINING. THE STRUCTURE DOES NOT DRY OUT DURING STAINING BECAUSE OF THE PRESENCE OF THE WATER-IMPERVIOUS MATERIAL.
