Abstract: A stator for an electric machine includes multiple conductive coils. Each coil defines a loop that extends axially through the elongate core, exits the core through an end face, and reenters the core through the end face. A first subset of the coils collectively form a first radial layer axially exterior the core and a third radial layer axially exterior the core. Each coil in the first subset resides in both the first layer and the third layer. A second subset of the coils collectively forms a second radial layer axially exterior the core and a fourth radial layer axially exterior the core. Each coil in the second subset residing in both the second layer and the fourth layer.

The invention includes providing an injection mold defining a mold cavity having a core pin positioned within the mold cavity. The mold includes at least one gate and multiple core support pins between the core pin and the mold cavity walls, with at least one primary core support pin positioned on a side opposite the at least one gate. The method also includes injecting a transparent molten polymeric material having high flow properties into the injection mold such that the polymeric material flows between the surface of the mold cavity and the core pin. The core support pins substantially prevent the core pin from shifting while the polymeric material is injected into the mold. The high-flow nature of the polymeric material allows for complete filling of the mold cavity.

Abstract: Semi-Automatic Number Verification (SNV) on an electronic adding machine employing a small amount of random access memory (RAM), a microprocessor, a printer link and printer, a piezo-electric speaker to facilitate conventional adding machine capabilities with the additional SNV feature employing an enable/disable (SNV) button. A keypunch operator depresses the SNV key to start the SNV process entering numbers with either the plus (+) or minus (-) key, entered appropriately into the RAM, and particularly an RAM module including first and second series arrays and first and second counters. When the operator depresses the TOTAL key, the printer is enabled, if it is currently switched on. The operator then enters the second series of numbers and the microprocessor compares the values to those stored in the RAM module. If a discrepancy is detected, the adding machine enters an edit mode in which the operator need only look at the original source document and the display for verification of entries.

Abstract: A method and apparatus in which one or more positive temperature coefficient thermistors heat air for application to printed stock in a printing press. The apparatus is preferably mounted on the press, located a short distance above stock traveling from a printing station to a delivery station. The apparatus directs air flow downward over or through the PTC thermistors and into contact with the printed stock. Preferably, variable-speed fans provide forced airflow for this purpose. The rate of heat output of the apparatus may be varied. The preferred PTC thermistors are supported on a frame of adjustable or variable length adapted to span the width of various transfer beds or printing presses to facilitate installation of the apparatus on presses of varying dimensions and configurations.
