Abstract: ABSTRACT       A series of signals are derived from respective transducers, fault detection switches, cubicle door interlock switches and the like at appropriate places in an industrial plant or apparatus.  The signals are taken to a system which monitors them for the presence of a fault indicating signal or other signal of interest.          The system has a series of scanner devices which are controlled by a logic circuit so as to scan the signals one after the other in a repetitive sequence.  Since the transducers, switches and such may be linked one with another so that, when one is producing a fault signal, others later in the sequence may also produce such a signal, the logic system operates so that when a fault signal is located, a further scanning sequence is gone through so that there is located the first transducer or switch in the sequence which is producing a fault signal.  This transducer or switch is then identified by a numeric or alpha-numeric display device.

Abstract: COATING MODIFICATION             PROCESS FOR ULTRAFILTRATION SYSTEMS     ABSTRACT OF THE DISCLOSURE       A coating modification process is provided for use in ultrafiltration systems to improve the adherence of porous coatings of preformed, aggregated, inorganic metal oxide particles, to substrates, particularly those com-prised of hollow tubular porous carbon members.  The process involves exposure of the coated members, during the initial treatment to water vapor at specific humidity, temperature and times.  The ultrafiltration systems so treated are particularly well-suited for prolonged use in the concentration and separation of oil from mixtures of oil, water and detergents, the recovery of polyvinyl-alcohol from textile wastes, and other useful applications.

Abstract: ABSTRACT     A system for filling slush molds with liquid as slip.          The containers are arranged along a line which is parallel with a guide track for a carriage.  The carriage has an arm that swings between a raised position, non-interferent with the containers and a second position below the carriage where the arm is in filling position.    The arm carries a filling nozzle which is intended to enter the mouth of the container.  The nozzle has a probe.          Electrical circuitry cooperating with the probe of the nozzle and sensing elements on the track and carriage are carried by the carriage.  The sensing elements along the track are spaced, respectively, the same as the spacing of the containers.  Each time a track sensing element is opposite the single different type cooperative sensing element of the carriage, the carriage will stop, the arm lowering the nozzle into the container mouth if permitted to do so.    The circuitry includes means for sensing whether a container is properly in position and raising the arm while holding back the flow of liquid if the container is missing or out of alignment.  If properly positioned and aligned, the arm will bring the nozzle into position to fill the container, will automatically sense when it is filled, stop the flow, raise the arm and cause the carriage to move to the next station.  The circuitry controls automatically the proper sequence of energizing and de-energizing the drive means moving the carriage and operating the arm.  The carriage is capable of moving to the end of the line and stopping, or returning fully to the line's beginning, or effecting the same filling operation in reverse.   ii

Abstract: METHOD AND APPARATUS FOR ARC WELDING  OF METAL PLATES FROM ONE SIDE ONLY          Abstract of the Disclosure A method and apparatus for arc welding of a pair of spaced steel plates from one side only using a grooved back-up plate which gives a good weld bead shape on the under side, gives high linear welding speeds, and avoids contamination of the deposited weld metal by the metal from the back-up plate.          A pair of consumable electrodes connected in electrical series between the output terminals of the power source and with one grounded to the workpiece are advanced into the weld gap on lines of movement which intersect at a point above the lower surfaces of the plates so that an arc is maintained between the electrodes spaced from the base of the back-up plate groove.  A separately energized electrode trails the first two electrodes and deposits a weld bead on the first deposited weld metal while it is still hot.

Abstract: ABSTRACT          This invention relates to a method and means for recording sweat gland activity which provides a dermatoglyph or pictorial representation which is directly proportional to the amount of sweat exuded by the glands   Some prior attempts have been made to produce such representations.  However, these prior attempts involve the use of potentially harmful or toxic chemicals, produce temporary discoloration of the skin surface to be recorded or are slow and time consuming to administer.  The present invention provides a pic-torial representation of the activity by physical con-tact of an iodide treated skin area with a dry sensitized substrate.  In one preferred embodiment, the sensitized substrate comprises a sheet material which has been coated with an aqueous solution of starch and a suitable oxidizing agent such as potassium persulfate.  Alter-nately, the dry sensitized substrate comprises a starch-oxidizing agent mixture which has been impregnated into an absorbent base layer.  With slight modification of the foregoing embodiment, the present invention also provides a method and means for obtaining inkless finger-prints by forming a sensitized coating in situ on a sub-strate.

Abstract: RCA 72,717 Abstract of the Disclosure A protection circuit for limiting the power dissipation of a video output amplifier when high frequency signals of significant magnitude and with a high density of occurrence (e.g., noise during vacant channel reception) are supplied to the amplifier.  The protection circuit includes a control transistor and a sensing network.  The sensing network monitors a video signal coupling path to detect the presence of high frequency signals, and derives a voltage representative thereof.  The derived voltage is insufficient to render the control transistor operative under normal signal conditions.  Under abnormal conditions when significant amounts of high frequency signals with a high density of occurrence are present, the derived voltage is sufficient to render the control transistor operative to develop an output control voltage.  The control voltage is applied to the video signal path so as to attenuate the signal including the high density components, such  that  excessive   conduction and power dissipation of the amplifier in response to the high density components is limited.

Abstract: TURBINE BLADE                      ABSTRACT OF THE DISCLOSURE           A convectively cooled turbine blade has a three-pass cooling air passageway.  Air enters the blade at its root end, travels along a reversing path through the passageway and is emitted through an array of slots in the blade trailing edge generally configured in the form of a Venetian blind.  Pedestals or turning vanes located in the turning areas of the passageway control separation of flow to prevent development of local hot spots.  Pedestals located in a midchord portion of the passageway prevent sidewall panel vibration and enhance cooling efficiency.
