IPC: H04M11/00

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 facilites.

Abstract: In a printing device having at least a pair of sheet discharge rollers (5a, 5b) for discharging a printing sheet on which a printing operation has been executed, provided are means (72) for judging whether the printing sheet exists or not at a contact position of the pair of sheet discharge rollers (5a, 5b), and control means (73) for controlling the pair of rollers (5a, 5b) so as to be brought out of contact in case that the sheet does not exist at the contact position. Thus, even if the sheet is skewed or bent, it is securely gripped between the pair of sheet discharge rollers (5a, 5b), thereby reducing occurrence of a sheet jamming.

Abstract: In a nuclear fuel bundle, an improved lock washer is disclosed for permitting ease of remote removal of hex nuts on tie rods for the remote submerged disassembly of fuel bundles after use in a reactor. The improved lock washer includes two spaced apart and interconnected tie rod surrounding washer members (30,32), each having radially inwardly extending keys (40). These keys register to corresponding keyways (42) in the threaded ends (44) of the tie rods to prevent tie rod rotation and threaded disengage­ment from a tie plate at the other end. Each washer member is manufactured from a spring material and includes at least one and preferably two radially protruding tangs (50). These tangs are elongate and bent in an inverted U-shaped configuration, including a gradual inward slope (66) defining a gathering surface between the tie rod and bolt on one hand and the U-shaped tang on the other hand. From the end of the gathering surface, the tang extends vertically downward in a position of spring interference with one of the flat sides of the hexagonal bolt (72) holding the tie rod in place. When the tie rod washer is in place with the nut fastened, the tang prevents the bolt from turning responsive to vibration and upward force on the upper tie plate due to outflowing water and steam. In remote dis­assembly of the fuel bundle, the gathering surface permits the tang to be biased away from the sides of the bolt by a specialized nut-gripping socket that penetrates intersti­tially between the lock washer and nut and captures the nut when it is unscrewed. The lock washer because of its spring action returns to its initial shape after the socket and nut are removed.

Abstract: An improved Packet Assembler/Disassembler (PAD) (200) optimizes the assembling of characters into packets for transmission over a packet network (150). The PAD is arranged to operably connect to and receive character asynchronous data from one or more terminal instruments (600) operating in either a block transfer mode or an echoplexing mode. Characters received by the PAD from a terminal instrument operating in an echoplexing mode are forwarded with no PAD delay. Characters received by the PAD from a terminal instrument operating in a block transfer mode are similarly forwarded with no PAD delay and in full packets with the exception of the last few characters of each block of characters which only partially fill their respective packets. And these partially filled packets are quickly forwarded in a time period which just exceeds the period required for the reception of a single character at the rate of data reception from the terminal instrument.

Abstract: A high-sensitive magnetometer has two SQUIDs each comprising a superconducting loop with one or more Josephson junctions and also has a coil comprising a continuous loop for providing magnetic flux of input signals to each of the SQUIDs in opposite directions. The magnetic flux of the input signals is detected by sums of output voltages of the SQUIDs. Magnetic flux noises equally applied on the two SQUID are cancelled by the continuous loop and at addition of the output voltages of the SQUIDs, thus large output signals can be obtained because sums of the two SQUID output signals are obtained.
