Abstract: ADDITION OF WATER TO REGENERATION AIR                         Abstract A process for economically converting carbo-metallic oils to lighter products.  The carbo-metallic oils contain 650°F and material which is characterized by a carbon resi-due on pyrolysis of at least about 1 and a Nickel Equiva-lents of heavy metals content of at least about 4 parts per million.  This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900 to about 1400°F, and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and lay-ins down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight.  The spent, coke-laden cata-lyst from the stream of hydrocarbons formed by vaporized feed and resultant cracking products is separated and regenerated in one or more regeneration beds in one or more regeneration zones by burning the coke on the spent catalyst with oxygen. The bed density is in the range of about 25 to about 50 pounds per cubic foot and the bed or beds are sustained by fluidization gas containing combustion-supporting gas having a linear velocity in the range of about 0. 7 to about 4 feet per second.  Liquid water is added to the bed or beds in a weight ratio of water to converter feed from about 0.01 to about 0.5 to a  least partly absorb the heat produced by the burning coke.  The catalyst particles are retained in the regeneration zone or zones in contact with the combus-tion-supporting gas for an average total residence time in said zone or zones of about 5 to about 30 minutes to reduce the level of carbon on the catalyst to about 0.25% by weight or less.  The regenerated catalyst is recycled to the reac-tor and contacted with fresh carbon-metallic oil.

Abstract: GAS METAL ARC WELDING METHOD                         ABSTRACT OF DISCLOSURE     A gas-metal-arc welding method is provided for high speed, high melting rate, substantially spatter-free, all-position welding. The method is particularly useful for out-of-position welding, that is, to produce vertical, inclined and overhead welds. A consumable wire electrode is held within and fed through the tubular contact tip of a continuous feed type welding gun having tubular nozzle surrounding and extending beyond the tip. A shielding gas, formed of unique ratios of a minor proportion of a carbon dioxide and oxygen mixture combined with a major proportion of an argon and helium mixture, is flowed in a substantially longitudinally laminar pattern between the nozzle and contact tip and along the electrode extension from the tip. The contact tip is cooled, and sufficiently high power electrical current is passed through the contact tip and electrode extension to produce the arc and to melt the end of the electrode into molten drops for short-circuiting (e.g., low current) or for spray (e.g., higher current) transfer of the drops to the weld deposit. The electrode extension is pre-heated by maintaining a long electrode extension or stick-out beyond the contact tip end, with a substantial portion of the extension recessed within the nozzle.

Abstract: ABSTRACT OF THE DISCLOSURE              Improved Cleaning Diskette for Flexible Disk Drive Transducers A flexible cleaning disk for universal application in single sided and double sided flexible disk drives has a jacket, a flexible cleaning medium rotatably positioned within the jacket and a removable protective membrane arranged to normally cover one of the jacket access apertures.  The protective membrane is a relatively thin flexible member fabricated from .002 inch polyester having a main body portion positioned within the interior of the jacket between the cleaning medium and the access aperture and a tab portion extending laterally from the main body portion and adhered to the outer surface of the jacket adjacent the access aperture.  The relatively thin flexible membrane provides a highly efficient transfer medium for the compressive force applied by the pressure pad assembly in a single sided drive and the movable transducer assembly in a double sided drive to the cleaning medium.  When used in a double sided drive, the membrane is removed during a second cleaning phase by releasing the tab portion from the jacket surface and withdrawing the main body portion from the access aperture.

Abstract: Abstract Method and Circuitry for the Function Control of Ultrasonic Alarm Systems In an ultrasonic alarm system, in which ultrasonic waves are continuously radiated within a surveilled area (R) and a frequency shift caused by a moved object, e.g. an intruder, is by virtue of the Doppler-Effect determined to be cause for the giving of an alarm, the function control of the system is effected during a test phase by means of brief aperiodic modulation of the ultrasonic waves.  The resulting brief broadening of the frequency produces in the same east circuit a signal (S2) if the system is functioning normally.  The duration of the modulation is chosen to be short enough so that no standing waves can form;  this ensures the trouble-free operation of the function control, even if the system, as a result of the vectorial addition of the received ultrasonic waves, accidentally experiences a lack of insensitivity; in this manner even the covering of the transmitter during a sabotage attempt can be identified and differentiated from a state of insensitivity.

Abstract: BIDIRECTIONAL OPTICAL DATA COMMUNICATIONS SYSTEM            Abstract of the Disclosure A system and method are disclosed for optically communicating data between two data handling units where one of the data units supplies all of the optical power needed for the optical communications between the two data units.  In a preferred embodiment of the invention a first data unit comprises a first data source, first and second optical sources of optical energy, and a first optical detector, while a second data unit comprises a second data source, a second optical detector and an optical modulator.  In a first mode of operation, a first stream of digital data from the first data source pulse modulates the first optical source on and off causing the first optical source to transmit optical pulses to the second optical detector in accordance with the first stream of digital data.  These optical pulses are converted by the second optical detector back into a representation of the first stream of digital data for use by the second data unit.  In a second mode of operation unmodulated optical energy is transmitted from the second optical source in the first data unit to the optical modulator in the second data unit.  A second stream of digital data from the second data source is applied to the optical modulator to modulate the received unmodulated optical energy by changing the reflectivity of the optical modulator in accord-ance with the second stream of digital data.  Modula-ted optical pulses from the optical modulator are therefore reflected to the first optical detector. These reflected modulated optical pulses are converted by the first optical detector back into a representa-tion of the second stream of digital data for use by the first data unit.
