Title: Salient pole rotor for a dynamoelectric machine
Inventor: DYMOND JAMES HENRY
IPC: H02K9/06
Filed: 1990-02-22
Granted: 1997-04-01
Abstract: A dynamoelectric machine has a stator with a stator core and a plurality of spaced apart radially extending ventilation ducts.   A rotor mounted for rotation within the stator has a shaft with a plurality of salient poles.  Each salient pole has a winding on it and each pole with its winding constitutes a pole member. Adjacent pole members define between them an interpolar space.  Cooling air enters each interpolar space from each end when the machine is operating, moves generally axially as portions of the air change direction to move radially outwards through the air gap separating the rotor and stator and then through the ventilation ducts. The air flow, in a radial outward direction, tends to be less at the ends of the rotor and through the ventilation ducts adjacent the ends of the stator.  The invention places a baffle at each end of each interpolar space. The baffle is in a generally radial plane and has an outward edge adjacent the outer limit of the interpolar space as defined by the tips of the poles, and an inward edge spaced from the bottom of the interpolar space.  The baffle improves the air flow radially outwards adjacent the ends of the rotor and the stator.

Title: Audible logo for identifying a common carrier
Inventor: BAUER THOMAS M
IPC: H04Q3/00
Filed: 1990-03-06
Granted: 1994-08-02
Abstract: This invention relates to the application of an audible logo to a telecommunications call, for identifying the common carrier serving that call. A call is received in an operator assistance system. After applying a calling card prompt tone and prior to connecting the call to an operator position or receiving further digits such as those for a calling card number, the operator assistance system connects an audible logo, identifying a common carrier, to the call. Advantageously, a telephone customer receives the information necessary to identify whether his/her preferred common carrier is going to be used on this call at a sufficiently early time to make it convenient to disconnect and reoriginate. This information is particularly important for calls originated away from home or office, calls that are likely to be operator assistance (0 or 0+ directory number) calls. Subsequently, the operatorassistance call is processed as in the prior art. Advantageously, this arrangement identifies the common carrier on the calls where this identification is most needed without adding holding time to all direct dialed station toll calls.
