Abstract: A  system  for  manufacturing  multiple  component assemblies  utilizing  semi-automatic  computer-assisted material handling.   The system comprises a plurality of component  selection  cells  each having  an  alphanumeric display to display a selected assembly model description and a plurality of component bins wherein each bin has an associated bin numeric display or backlight pushbutton switch for displaying the quantity of components from that bin required for a selected assembly model.  Each numeric display pushbutton switch has a means for clearing the display after the required quantity of components has been selected and for generating a control signal in response to a completion of a selected collection of parts for that cell relating to the selected assembly model.  A computer controls the alphanumeric, numeric and pushbutton switch displays responsive to data entered by an operator relating to the selected assembly model number and controls the clearing of the alphanumeric displays in response to the control signal.  Flow racks are also provided for storage of collected kits of parts with a display associated with each rack including a pushbutton switch for indicating when each kit of parts is stored.

Patent CA-2008422-A1 (CA)
IPC: H04Q11/04
Filed: 1990-01-24
Abstract: This invention relates to methods of establishing facsimile (fax) connections. If a call is originated from a fax source and the destination is a voice station, then the call will be automatically redirected to a fax machine designated to receive fax messages for the voice station. A fax call is detected by a class of service indication in a local switching office, or by having a number forwarded to a toll office from a local office by Automatic Number Identification (ANI) of the caller that is one of a list of fax numbers. When it is determined that a call is a fax call, a fax indicator is sent with Common Channel Signaling (CCS) messages for that call. If a call with a fax indicator is received in a destination switching office, then the destination office checks to see if the called number is a fax number, if not, translation is made to find the number of a fax station for serving fax calls to the called number, and the call is completed to that fax station. Advantageously, customers need not know a fax number to transmit a fax message to an intended recipient. Three types of problems arise in treating such calls: recognition that the call is a fax call, transmitting that recognition to a far end switch, and redirecting the call at the fax end switch. Among the other techniques used for recognition are a fax class mark in an originating message from an Integrated Services Digital Network(ISDN) line or a dialed prefix such as #, #3, or an alternative common carrier code (10XXX) from an ordinary line. The redirection includes automatic redirection to a store and forward system on busy or no answer, routing to one of a plurality of alternative destinations based on the day and time, screening junk fax, and lighting a fax message waiting lamp on the called (voice) destination. For international calls, a translation from voice to fax may be made at an egress gateway switch; the fax calls may also be automatically routed over low distortion international transmission facilities.

Title: Power-on password functions for computer system
Inventor: WATTERS JEFFREY S
IPC: G06F21/00
Filed: 1990-01-25
Abstract: POWER-ON PASSWORD FUNCTIONS                     FOR COMPUTER SYSTEM                            ABSTRACT      A power-on password security function for a digital computer system allows the system software to distinguish between authorized and unauthorized users.  Safeguards are made against corruption of password data which could lead to lock-out authorized users, and redundant checks allow the security function to operate even when first-level checks fail.  The battery-powered RAM storage area used to hold the password when the system is turned "off" is protected against being accessible by unauthorized users when the system is turned "on".

Title: Flush rolled joint
Inventor: HUNTER TERRY A
IPC: G21C3/10
Filed: 1990-12-20
Abstract: FLUSH ROLLED JOINT                     Abstract of the Disclosure There is disclosed an elongated pressure tube suitable for use in a nuclear fuel channel.  In this environment, pressurized water passes through the pressure tube extracting heat from fuel bundles carried in the pressure tube.  The pressure tube has an upstream end portion that is adapted to have its outer surface roll joined to an inside surface of an end fitting of dissimilar material.  The inside surface of the end fitting has a plurality of recessed grooves contained therein to facilitate the rolled joint.  The upstream end portion of the pressure tube initially has a greater wall thickness and a smaller inside wall surface diameter than the remainder of the pressure tube.  To form the rolled joint, a roller is placed inside the upstream end portion to apply outwardly directed force to the inside wall surface of the end portion causing the inside wall surface diameter of the end portion to become flush with the remaining inside wall surface of the pressure tube. During the formation of the rolled joint, material from the end portion flows into the recessed grooves of the end fitting.  By providing a "flush" rolled joint in the final assembly of the fuel channel there will be no discontinuity in the inside wall surface of the pressure tube. The discontinuity in the inner wall surface diameter at the roll joint of the prior art pressure tube has permitted the fuel bundle to vibrate and to fret the pressure tube adjacent the rolled joint.
