Abstract: ABSTRACT OF THE DISCLOSURE     Isomerization of xylenes in admixture with ethylbenzene by contact with a zeolite catalyst such as ZSM-5 is improved by use of zeolite which has been steamed at high temperature to reduce activity, the reaction being carried out at a temperature of 371 to 427°C. At these conditions, conversion of ethylbenzene follows a reaction path which permits high conversion of ethylbenzene to benzene without loss of xylenes by disproportionation.

Abstract: A B S T R A C T      A fibrous web carried by a thin band disposed on a conveyor passes under a number of spray tubes which pour thereon a plastic material under liquid form which has been de-gassed under vacuum in a gas eliminating apparatus.  The liquid absorbs gases from the fibres and overflows laterally into a lower trough from which it is recycled into the gas eliminating apparatus.  The web is thus progressively de-gassed and impregnated with de-gassed plastic material.  It is then covered by another thin band to form a sandwiched complex product for further operations.

Abstract: JT&C Docket 02-75 BAR CODE READER SYSTEM            Abstract of the Disclosure A reader system for optically scanning a bar code and processing the resulting video signals to produce corres-ponding digital signals is disclosed.  The scanner comprises a camera  having an image sensor which converts the varying black and white bar code image into a corresponding analog video signal.  This signal is fed to a dynamic threshold de-tector which tracks the midpoint voltage value of the video signal and applies this value to a comparator, where it is compared to the analog video signal.  The output of the com-parator provides a train of logic states "0" and "1" repre-senting video levels below and above the midpoint voltage value, respectively, thus producing a digitalized video signal corresponding to the bar code.  The digital signals are filtered to mask single bit aberrations, with the filter pro-ducing a series of logic "0"'s and "1"'s at the clock rate of the system, each of which represents the output of a single "pixel", or picture element, of the image sensor, the output level indicating whether the pixel has sensed a black or white bar.         The number of consecutive pixels having "0" or "1" output levels are counted and compared to preset values to determine whether wide or narrow code bars are being sensed, and this information is stored in digital form in one of two serial memories.  At the same time, the total number of bars scanned is counted, and the memory is inhibited when the count equals the number of bars in the code.     At the completion of a first scan of the bar code image, the storage of information is switched to the other serial memory and the bar code scanning process is repeated while the data just stored in the first memory is processed, for example, in a conventional bar code-to-numeric or alpha-numeric converter for display.  Multiple scans of the bar code insure an accurate readout.

Abstract: ABSTRACT OF THE DISCLOSURE       This invention relates to a suction dredger having a central hold and air chambers located on both sides of the hold, which central hold has an overflow to the outside of the hull and an overflow to the air chambers.  The last-mentioned overflow is controlled by valves for opening and closing, respectively this overflow, valving being provided for unloading the central hold.  The known suction dredger has a complicated hull construction to allow overflow from the central hold to the outside of the hull or into the air chambers.  To empty the air chambers suction tubes are placed at the bottom level of the air chambers.  The air chambers can be used to receive a dredged mixture in case the specific weight of this mixture is low and then serve to increase the volume for taking up dredged mixture.  According to the present invention a simpler construction of the hull is possible which can be applied to existing suction dredgers by providing the air chambers with bottom walls that incline downwardly towards the central hold and by providing discharge valves between the air chambers and the central hold at the bottom of the air chambers.

Abstract: ABSTRACT OF THE DISCLOSURE         A tube is inserted to a predetermined depth into the dip stick orifice of an internal combustion engine of a vehicle and connected to a small pump to initiate oil circulation in a line between the dip stick orifice and the oil filler tube.  A pressure sensitive switch is inserted in this line and held in a normally open position while sufficient pressure is being sensed. When the oil level of the engine falls below the tube, the oil pressure sensed by the oil sensor switch drops and the contacts close lighting an indicator light disposed on the instrument panel of the vehicle.  An oil reservoir is positioned above the engine and is connected to the oil filler tube.  A valve is disposed between the reservoir and the oil filler tube of the engine and can be operated through a remote control from inside the vehicle.  When the oil warning light is actuated, the vehicle operator can actuate the valve to allow a predetermined amount of oil to flow into the engine.

Abstract: ABSTRACT OF THE DISCLOSURE         A heating apparatus for microwave ovens, electric ovens, gas ovens and ovens of the hybrid type, includes a digital control unit and a numerical display unit.  The heating apparatus further includes numeric value input means (an impulse giver) including a digit change-over switch and a setback switch as means for entering a numerical value such as a heating time or a heating temperature into the digital control unit.   The digit change-over switch always directs one of the hours, minutes and seconds, and the setback switch is designed so that the switch which is usually held off is closed only when the knob is moved or when the knob is depressed, for example, and the switch is returned to the original off position upon releasing the hand, thus reducing the number of setting keys, lessening the possibility of erroneous setting and simplifying the setting of heating time, heating temperature or the like.

Human neoplastic cells are developed for fusing with immunized lymphoid cells to provide stable human-human hybridoma strains producing complete monoclonal antibodies for a predefined antigen.  From a myeloma cell line, rapidly growing 8-azaguanine resistant HAT sensitive cells are selected.  The selected myeloma cells are crossed with immunized lymphoid cells and the resulting cell mixture grown under controlled selective conditions.  Lymphoma cells may be substituted for the myeloma cells.  After expansion of the desired hybridoma cells, the monoclonal antibodies may be harvested.  The hybridomas serve as a source for messenger RNA for light and heavy chains which may be used for production of light and heavy chain immunoglobulin proteins through hybrid DNA techniques.

Abstract: ABSTRACT     An electrode for use in electrolytic processes comprises a base of film-forming metal such as titanium with an operative outer electro-catalytic surface which is an integral surface film of a compound of the titanium base, usually the oxide, incorporating a platinum-group metal electrocatalyst, preferably iridium, rhodium, palladium and/or ruthenium as metal or oxide. The surface film is formed by the applica-tion of a dilute solution of a thermodecomposable iridium, rhodium and/ or ruthenium compound containing an agent such as HC1 which attacks the titanium base and converts metal from the base into ions which are converted to the compound in a subsequent heating step. The concentrations of this agent and of the thermodecomposable compound and the number of applied layers are such that during heating the electrocatalyst formed from the decomposed compound is incorporated fully in the surface film formed from the base. The base is usually in sheet form, but may also be a powder.
