Abstract: Abstract An orderwire communication scheme for a fiber optic communication network includes terminal station equipment associated with the central offices at opposite ends of the network and signal regenerator equipment at the repeater sites disposed between the terminal stations.  The communication format along the link is a data-over-voice scheme, the data being digitally encoded on an FSK modulated carrier.  In carrying out supervisory functions with respect to each of the stations along the link, command messages are conveyed from the terminal stations at one of the central offices to respective stations along the link in the form of command instructions.          Each command message from a central office's terminal station contains the address of the recipient station for whom the message is intended followed by a specific encoded instruction. the instruction may contain z request for information from the addressed site as to equipment conditions at the site and/or a directive that the equipment at the site perform a particular task.  In reply to the command message sent to it, the addressed site transmits a response message back to the source station, representative of the status of a particular equipment condition or operation as requested by the command instruction.          In this manner, supervisory personnel at each central office may remotely monitor and control the operation of the communication equipment at the various sites along the link and thereby take correction maintenance or protection channel substitution action where and when required.  The digital message transmission scheme also provides facility for fault/alarm reporting, testing the bit error rate of individual channels of the repeater and the transceiver equipment at each terminal station when requested, and is used for paging signalling between central offices.

Abstract: Abstract:    A method is described for breaking a water-in-crude oil emulsion.  A crude oil feedstock is tangentially injected into the upper portion of a vortex chamber operating on the vortex principle with the emulsion rotating within the chamber and the velocity of the emulsion increasing toward the center of the vortex whereby concentric layers of emulsion having different tangential velocities apply shear stresses to the dis-persed water in the crude oil causing the interfacial film between the water and the oil to rupture.  This enables chemical demulsifiers, added prior to the vortex operation, to act more quickly and efficiently.  There-after, the dewatering of the crude oil is easily accomplished by usual methods.

Abstract: ABSTRACT      A front for test patterns is made programmable by programming individual "characters" to be displayed on a video display.  The individual characters are assigned memory locations and can be adjusted in height and width, as well as in color and intensity.  Complex characters are formed by programming additional features onto a character memory space assigned to each character.     The system provides a greater ratio of pattern generating capa-bility-to-required hardware, while providing most features of a fixed character generator.  The system's programmability is particularly adapted to use with a test system which has capabilities of increment-ally varying scan rate and raster patterns, as well as a capability of random stroke and fixed mode stimuli generation.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a dynamic semiconductor memory cell with random access (DRAM), in which a bit line and a storage capacitor electrode consist of a doped silicide of a metal of high melting point.  The length of the transfer gate is defined by the spacing of the silicide on the bit line and on the silicide of the storage capacitor electrode.  The invention relates also to a method for its fabrication.  Due to the self-aligning (S/D) contact and through the use of the silicide a higher packing density and a very low-resistance bit line are made possible.  The gate length does not depend on the adjustment accuracy as it is defined by the spacing of the silicide-bit line and silicide electrode.

Abstract: METHOD AND SYSTEM FOR STARTING A MOTOR-COMMUTATED SCR INVERTER            ABSTRACT:       Highly reliable and consistent starting of an SCR inverter-motor system is achieved by first initializing the rotor position, namely establishing the rotor in a known starting position.  Thereafter, the inverter is operated synchronously in a second mode with predetermined pairs of the inverter SCRs being sequentially gated into conduction at an increasing frequency to current pulse enerqize the motor to effect step-by-step rotation of the rotor at a faster and faster rate, the motor current being reduced to zero at the termination of each energizing pulse to force commutate the conducting pair of SCRs. After the motor has reached a preset speed, operation in a third mode occurs and the inverter is synchronized with the motor, gating of the SCRs being controlled by the motor voltage in order that the rotor position will be synchronized to the revolving magnetic field created by the stator.  During this third operating mode the motor speed continues to increase and the SCRs are forced commutated, as a result of which the rotor follows the stator magnetic field very closely and synchronization will be perfected.  When the motor subsequently reaches a given speed sufficiently high to permit motor commutation exclusively, the starting system switches to a fourth and normal running mode wherein the gating of the inverter SCRs continues to be synchronized with the motor and controlled by the motor voltage, but the SCRs will now be commutated only by the motor voltage,
