Title: Inter-exchange carrier access
Inventor: BILLINGER RANDY J
IPC: H04Q3/62
Filed: 1987-12-07
Granted: 1990-12-04
Abstract: INTER-EXCHANGE CARRIER ACCESS            Abstract This Inter-Exchange Carrier Access arrangement uses the Automatic Number Identification (ANI) capability of the central switching office to eliminate the need for the customer to dial an authorization code when accessing an inter-exchange carrier via a facilities reseller telephone communication system.  The central switching office transmits the calling party identification (ANI) digits to the facilities reseller telephone communication system when the customer dials the remote access code for the facilities reseller telephone communication system. These received ANI digits are compared by the facilities reseller telephone communication system with a list of authorized customers stored in memory.  If a match occurs, the identity of the inter-exchange carrier preselected by the customer is retrieved from memory and the telephone communication system automatically outpulses the inter-exchange carrier access code to the central switching office.  Once connected to the selected inter-exchange carrier, the telephone communication system completes the call by transmitting both the called number and the customer's personal identification code to the inter-exchange carrier.  The customer thereby has "dial 1" access through the facilities reseller telephone communication system to this inter-exchange carrier.

Granted: 1992-06-23
Abstract: ABSTRACT OF THE DISCLOSURE           Porgings fabricated from 9 Chromium - 1 Molybdenum, modified alloy  are subjected to tempering at a temperature less than the ASTM specified minimum tempering temperature in the range from about 1275 °F to about 1300 of for a period of time in the range of from about 5 to about 20 hours to cause the forging to have a room temperature yield strength in the range from about 85 to about 100 ksi.  Such room temperature yield strengths permit the use of the alloy in the fabrication of high-pressure steam turbine rotors.  Forgings fabricated from such alloys possess excellent high-temperature properties and the same are also weldable to facilitate repair of rotors fabricated therefrom and to facilitate the fabrication of the rotor in the first instance by forming the rotor from smaller sections which may be welded together and subsequently tempered at a temperature in the range from about 1275 °F to about 1300 °F.

Title: Low deflection force sensitive pick
Inventor: HERTEL RICHARD J
IPC: H01L21/677
Filed: 1988-03-09
Granted: 1990-11-13
Abstract: Abstract of the Disclosure A tactile pick includes a base and a lever attached beneath the base by a pivot.  A load sensing device including a strain gauge is located between the base and the portion of the lever on one side of the pivot; the portion of the lever on the other side of the pivot is adapted to receive a semiconductor wafer.  Rotation of the lever about the pivot induced by the weight of a wafer causes an actuator to depress a flexible member on which a strain gauge is mounted.  The output signal of the strain gauge is processed by a controller to provide an output signal which varies monotonically with the magnitude of the weight placed on the wafer receiving portion of the lever.  The pick is employed in connection with the wafer transport system which transfers wafers from a cassette to the pick lever.
