  • Publication number: 20240099173
    Abstract: Tine assemblies (100a, 100b, 104) are secured by a single bolt (126) extending diametrically through each tine (120) located in a cavity (112) of a tine plate (110). An outer tine assembly (104) is connected to a sleeve (116) rotatably mounted on independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are connected. A tine cover (50) removably closes an opening (40) in the top plate (28) and in which weights (70) are removably received over the tine assemblies (100a, 100b, 104). Transport wheels (134) are moveable by pivoting a stop plate (140) to position an upper pivot axis (150a) of an abutment bar (150) ahead of or behind the stop axis (142) and lower pivot axis (150b). A stop (146) positioned on the stop plate (140) without the use of tools adjusts the depth of the tine assemblies (100a, 100b, 104).

  • Patent number: 6528277
    Abstract: This invention relates to a container and method for detecting a specific environmental parameter or combination of parameters, or for determining the effectiveness of a sterilization procedure. The invention relates to test indicators containing controlled volumes of compressed, gas-permeable materials, and modified caps comprising one or more apertures, sterilant permeable inserts, protruding members, or a combination thereof, and to methods for using test indicators for determining the efficacy of different types of sterilization processes. If proper sterilization conditions are not met, the interactive enzyme system remains active, and a color product forms upon the addition of the remaining components of the enzyme system. If the proper sterilization conditions are met, the sterilant destroys the interactive enzymes and no color product is formed. Inactivation of the enzyme system parallels the inactivation of bacterial spores subjected to the sterilization process.
