Abstract: UPGRADING OF RESIDUAL OIL          ABSTRACT:          This invention provides a process which involves visbreaking of a heavy hydrocarbon oil in the presence of a suspension of coal particles of 20-2000 micron size.  The presence of the fine coal solids permits severe visbreaking conditions which increases the yield of fuel range distillate products.  Coke deposition occurs on the surfaces of the coal particles rather than on the surfaces of the heater chambers.  The coal particle surfaces also serve to catalyze demetallation of the heavy oil feedstock, and to adsorb demetallation deposits.

Abstract: TELEMETRY SYSTEM FOR CENTRIFUGAL WATER CHILLING SYSTEMS ********************************************************                      ABSTRACT OF THE DISCLOSURE      A telemetry system for reporting the status of a number of physical parameters occurring during operation of industrial equipment, such as the monitoring of refrigeration/air condition-ing safety controls and anticipatory refrigeration controls.          Activation of the safety or anticipatory controls generate electrical signals to activate a four input alarm transmitter, which automatically dials a pre-programmed telephone number and reports the status of the various inputs to a special monitor receiver at a remote location.  An interface board is coupled to the safety and anticipatory controls, and multiplexes the signals therefrom into four transmitter inputs.  An indicator panel connected to the interface board provides a maintained visual indication of which input(s) have caused a transmission. The anticipatory controls are set to trip before the safety controls, which latter controls effect shut-down of the system, and provide anticipatory signals warning of impending system problems.

Abstract: DOWNHOLE STEAM GENERATOR USING LOW          PRESSURE FUEL AND AIR SUPPLY           ABSTRACT OF THE DISCLOSURE     An apparatus for generation of steam in a borehole for penetration into an earth formation wherein a spiral, tubular heat exchanger is used in the combustion chamber to isolate the combustion process from the water being superheated for conversion into steam.  The isolation allows combustion of a relatively low pressure oxidant and fuel mixture for generating high enthalpy steam.          The fuel is preheated by feedback of combustion gases from the top of the combustion chamber through a fuel preheater chamber.  The hot exhaust gases of combustion of the bottom of the combustion chamber, after flowing over the heat exchanger enter an exhaust passage and pipe.  The exhaust pipe is mounted inside  the water supply line heating the water flowing into the heat exchanger.  After being superheated in the heat exchanger, the water is ejected through an expansion nozzle and converts into steam prior to penetration into the earth formation.  Pressure responsive doors are provided at a steam outlet downstream of the nozzle and close when the steam pressure is lost due to flameout.

Abstract: RCA 76,841 ABSTRACT OF THE DISCLOSURE A method and apparatus are presented for detecting the presence of ghost signal contamination of a video signal by examining the picture information interval of the video signal.  A baseband video signal is detected and examined to detect signal transitions.  Transitions of the main video signal of a given polarity will be followed by corresponding transitions of a ghost signal.  The time intervals between ones of the transitions are measured and stored.  If a ghost signal is present, the time interval between corresponding ghost and signal transitions will occur more frequently than the relatively random time intervals between transitions of the main signal and the ghost signal considered separately.  By correlating the time interval measurements, the recurring time interval between corresponding main and ghost signal transitions can be identified.  This information may then be used to adjust the delay of a delay line in a ghost cancellation system.

Abstract: ABSTRACT      Metal substrates in corrosive environments, such as gas and oil pipelines, are normally prone to embrittlement caused by absorption of the hydrogen atoms cathodically evolved during various corrosion proceses.          This is substantially prevented by providing an active substance in the vicinity of the metal substrate, and in electrical contact therewith, the active substance being a sulphide or mixed sulphide of a metal of Group Vb, VIb or VIIb of the Periodic Table or of a rare earth metal, especially WS2 and MoS2.The active substance is preferably applied as or in a coating on the surface of the substrate, with an overcoating of, for example, a thermosetting resin, preferably being employed for mechanical and environmental protection.

Abstract: BRAKING METHOD AND APPARATUS FOR VIBRATORY FEEDER                         ABSTRACT         A material dispensing apparatus including drive means for driving à feeder bowl is disclosed.  A control circuit for controlling the drive includes a Hall effect amplitude sensing transducer for monitoring the magnitude of bowl vibrations and a braking circuit for controlling the damping of vibratory motion after the requisite amount of material has been fed from the feeder bowl.  The braking circuit selectively reverses the current flow through a drive coil which comprises a portion of the drive circuitry of the apparatus.  This current reversal disrupts the rhythm of forced oscillations which feed material from the bowl and causes bowl motion to be damped.  A mechanical brake coupled to the bowl complements the braking action of braking circuit and locks the bowl in place to prevent accidental dispensing of parts.

Abstract: IMPROVED NON-VOLATILE MEMORY SERIAL NUMBER     LOCK FOR ELECTRONIC POSTAGE METER                 ABSTRACT OF THE DISCLOSURE        An improved serial number lock for inclusion in a non-volatile memory of an electronic postage meter is provided.          The non-volatile memory is arranged to provide a field to accommodate a postage meter serial number.  The serial number is entered into the meter at the end of the manufacturing process after the meter has been assembled and the components tested.  The postage meter includes a routine programmed into the read only memory which is used only once during the life of the meter's non-volatile memory.  The routine requires the check of a non-volatile memory location which has been set once the routine has been successfully completed.  The setting of this bit prevents reentry into the one time pro-gram.  The program can be reused until the bit is set.  The bit is set by comparision of the data included in a received message with the value of the data contained in non-volatile memory.  If the comparision is true, the bit is set.      The serial number message format includes an opera-tional BCD digit as an operational indicator.  If the serial number has been entered and the operational indicator set to zero, the serial number will be changed to the value con-tained in the data message.  If the operational indicator is a one, the firmware will examine the serial number presently contained in non-volatile memory, and compare it with the value contained in the serial number message.  If the result is favorable or true, the program will set the non-volatile memory lock bit thus preventing further access to this program.
