Abstract: A ladder is provided having a base section and a fly section slidably coupled with the base section. The base section includes a first pair of spaced apart rails and a first plurality of rungs extending between and coupled to the first pair of spaced apart rails. The fly section includes a second pair of spaced apart rails and a second plurality of rungs extending between and coupled to the second pair of spaced apart rails. The various rungs may be coupled with their associated rails in an offset relationship such that they are not centered along a longitudinal center axis line of the rails. A rung lock device may be used which includes an arm pivotally coupled with the base section and configured to selectively engage various rungs of the second plurality of rungs to maintain the fly section in a desired position relative to the base section.

Abstract: A computer is used to generate dynamic supply chain delivery options for a product. Data is received at the computer, regarding a delivery of a product to a customer, the delivery is implemented using a delivery system. A change in a delivery time or location of the product is determined using the computer based on updated data received at the computer. A simulation is generated, using the computer, of simulated delivery plans based on the received data and the updated data. The simulated delivery plans are evaluated to determine an updated delivery plan based on parameters. The updated delivery plan is selected based on the parameters, and communicated to the delivery system.

Abstract: The use of adhesives formulated with up to 40% foam in paper cores and tubes for the tissue, towel, carpet, textile, plastic film, paper, food and industrial storage industries.

Abstract: An apparatus and method for manufacturing a core or tube using radio frequency. When using aqueous-based adhesives, application of radio frequency allows for a much more efficient and much quicker method for drying and curing.
