Abstract: A roll of controllable flexure having a cylindrical inner part and a tubular outer part surrounding the inner part and mounted rotatably at both its ends on the inner part. A heating strip is disposed along a generatrix on the inner part. At least one electrical temperature sensor is disposed in the inner part in the immediate vicinity of the heating strip and at least one additional electrical temperature sensor is disposed on the opposite side of the inner part. The two temperature sensors are connected to a temperature difference measuring apparatus and control an electrical regulating circuit to which a power circuit containing the heating strip is connected. The power delivered to the heating strip is so regulated that a preset temperature difference between the heated and unheated sides of the inner part is maintained. The different thermal elongation of the unheated and heated sides of the inner part produces an arching of the inner part which is transmitted to the outer part. The side of the inner part that faces away from the heating strip can be cooled.

Abstract: A calculator having semi non-volatile memory capability (data retention) utilizing a CMOS process, a low power microcomputer with on-chip and external data retention capability, and multiple partition power control of circuit groups. Incorporation of a first and second switched negative voltage and a non-switched negative voltage to the appropriate P (-) wells enables the clocked logic and the display interface and keystroke detect circuitry to be turned off while power is maintained on the internal static RAM, and on the RAM write logic, digit latches, and R-lines which connect to both the internal and external RAM, or to selectively connect in combination the first and second switched voltages. In an alternate embodiment, a multiple oscillator, multiple partition system is controlled to provide an off-mode, display only mode (low frequency oscillator), a process only mode, and a display and process mode, thereby optimizing power dissipation to system requirements. In yet another embodiment, the clocked CMOS logic of the system is forced to a designer predefined output logic level in the inactive power down mode. Thus, semi-non-volatile memory capability, power down standby, and display only capabilities may be achieved (Figs. 3a-3d).

Inventor: CONNELL TALBERT DUANE
IPC: B23K9/127
Filed: 1981-01-21
Abstract: A floating reference voltage is generated in response to the low frequency components of weld current and is utilized in the control of the width of travel of a welding arc back and forth across a gap to be filled with weld metal. The arc current is integrated during each traverse across the gap and this integral is compared with the floating reference so that as the wall of the gap is approached, the direction of travel of the arc will be reversed. Follow-up control affords a start-up phase comparing the integration product with a fixed reference voltage and transferring the comparison to the floating reference voltage upon the latter obtaining a conditional given value. Provision is made for avoidance of the effects of the arc welding phenomenon of "dip transfer".
