Title: Static electricity meter and process for calibrating the same
Inventor: BAER HANSPETER
IPC: G01R35/04
Filed: 1986-04-16
Granted: 1989-08-24
Abstract: An solid-state electricity meter includes an electronic measuring unit with an analog/digital converter which receives signals from amplifiers for various measurement ranges, and a control section with a microcomputer wherein the meter signal is processed, taking into account correction factors for the various elements of the circuit. Each correction factor is a single value for each respective measurement range, and the correction factors for each range are contained in corresponding meter-characteristic quantities which are stored in the electricity meter. Each meter-characteristic quantity represents a measurement value corresponding to a specific quantity of energy. Only a few (e.g., only 4) meter-characteristic quantities need be stored in the electricity meter. These meter-characteristic quantitites can be determined in a conventional calibration procedure, and they enable all the fixed errors of the signal processing to be compensated.

Title: Method and apparatus for producing coreless rolls of sheet material and a coreless roll of material
Inventor: SALZSAULER DONALD J
IPC: B65H75/24
Filed: 1998-02-10
Granted: 2001-05-10
Abstract: A roll of sheet material, such as plastic film wrap, having an inner layer wound at low tension and an outer layer wound under greater tension provides a coreless roll. Eliminating the need for a core reduces the cost of producing rolls of sheet material, and reduces the weight and outer dimensions of the roll with a consequent reduction in shipping and storage costs. An apparatus and method for producing such a roll, from a pre-wound master roll or as part of a production line for forming the sheet material, involves varying the longitudinal tension applied to sheet material as it is wound onto an expandable mandrel. After the roll has cured, the mandrel is collapsed and disengaged from the roll to provide a coreless roll. The mater roll can be prestretched prior to forming the coreless roll, if desired, and can be prestretched as a step in the formation of the coreless roll.
