IPC: G01N33/34
Filed: 1994-07-25
Abstract: The invention provides a method and apparatus for testing the chew-out strength of paperboard cores. The apparatus of the invention includes a clamping element for clamping a tubular core to prevent rotation thereof; a splined chuck element in the form of an axially tapered member having a plurality of circumferentially distributed splines for insertion into one end face of the core; and a means for applying increasing torque at a controlled rate to the splined chuck element.  A measuring means measures the torque applied to the splined chuck element.  In operation, increasing amounts of torque are applied by the torquing means until the splined chuck element shears the end face of the tube resulting in chew-out of the core.  The maximum torque force applied to the splined chuck element provides an accurate indication of the chew-out strength of the core.

Title: Method to predict active growth of bacteria adhered to a surface
Inventor: BLOOMQUIST CYNTHIA G
IPC: C12N1/21
Filed: 1994-01-14
Abstract: The present invention described provides a start microbial replication factor, as well as methods for assaying and using the start microbial replication factor. A start microbial replication factor can be used to stimulate the growth of bacteria in suspension or bound to a surface. Agents that inhibit or enhance a start microbial replication factor can also be identified. The present invention also describes processes to treat or control the growth of bacteria which are bound to surfaces. Both proliferation and metabolism of bacteria which are adhered to surfaces are independent of both time and nutrient supply. Growth of adherent bacteria is density dependent. The present invention also provides a process to predict when bacterial growth will exhibit rapid growth on a surface. The invention also provides novel strains of transformed bacteria and methods of using the bacteria strains to measure microbial growth in the presence or absence of a start microbial replication factor. The transformed bacteria have a bacterial reporter gene under the control of a promoter whose expression is coordinately regulated with cell growth.
