Abstract: ABSTRACT          A feed gas mixture with SO2 partial pressure of at least about 0.5 atmosphere and an O2:SO2 mole ratio of between about 0.7:1 and about 1:1 is passed in plug flow through a packed bed of conversion cata-lyst.  The catalyst bed is cooled to produce a temper-ature profile including a first zone of increasing temperature, a second zone of substantially constant temperature and a third zone of declining temperature. The exit temperature is sufficiently low for high equilibrium conversion values.  The effluent is cooled to condense liquid sulfur trioxide, while the sulfur trioxide remaining in the gas stream can be absorbed into oleum and/or sulfuric acid.  Enriched oleum can be prepared by blending condensed sulfur trioxide into oleum or sulfuric acid.

Abstract: GAS SENSING APPARATUS AND METHOD            ABSTRACT OF THE DISCLOSURE           A sensing apparatus and method for qualitatively and quantitatively analyzing small amounts of selected oxidizable gases in a carrier gas including the associated electronic circuitry is described.  The apparatus pre-ferably includes two semi-conductor type sensing elements in electrical parallel so that the difference in resis-tance of the two sensors can be detected, which can be of the N or P type and which decrease or increase in electrical resistance as a function of the concentration of an oxidizable gas.  Also, a method for determining fruit maturity and ripeness by the detection of ethylene in the internal atmosphere of a fruit is described which preferably uses the apparatus with the semi-conductor type sensing elements, but can use other variable resistance type gas sensing means.

Abstract: ABSTRACT OF THE DISCLOSURE:                  A sheet winding in a transformer is made with double-curved conductor sheets.  Some of the winding turns are mutually different as regards the curvature visible in an axial section.  This has been achieved by arranging a number of filling members at each one of the end surfaces of the winding.  Each filling member contains several turns of a filling tape, which are evenly distributed in a group of mutually adjacently positioned winding turns wound from a conductor sheet.  Because the filling tape has different degrees of overlap in the different turns of the conductor sheet, the filling member will have approximately the same effect as a filling body which, in axial section, exhibits a wedge-shaped cross-section area.

Abstract: VALVE OPERATOR CONTROL SYSTEM                       ABSTRACT          A control system for a valve actuator which is subject to oppositely directed displacement due to thermal expansion and spring forces has sensor switches which detect successively greater amounts of compression of a spring which compresses to accommodate thermal expansion of the valve, its stem and seat when the valve is seated in closed position.  A position servomechanism which is responsive to the position of the stem and a control signal operates a motor for advancing and retracting the stem.  Separate control devices, which are two way valves when the motor is a fluid motor and the servomechanism is a fluid operative servomechanism, are controlled by the sensor switches to stop the motor from overcompressing the spring when first position of the spring is reached and to operate the motor to retract the valve back to the first position when the second position is reached whereby to maintain a pre-determined bias forcing the valve against the seat due to the spring forces in spite of thermal expansion of the valve, its seat and stem.

Title:     High Head Centrifugal Slicing Slurry Pump ABSTRACT         A booster propeller is located at the inlet of a flared funnel leading toward arcuate inlet apertures in an end plate of a centrifugal pump casing.  The pump impeller is received in a bowl capped by the end plate and has a circular shroud plate perpendicular to the axis with vanes or blades projecting toward the end plate and having cupped leading surfaces forming a sharpened edge.  Such blades are swept back in the area of the end plate inlet apertures for effective slicing of chunks or lumps of solid material in the slurry in combination with sharpened leading edges of the inlet apertures.          The pump casing bowl has a semicylindrical wall portion closely encircling the impeller and providing a pressure-increasing zone for slurry accelerated outward before the bowl wall spirals volutely outward to the outlet conduit.

Abstract: FOOD PRODUCT DEFECT SENSOR AND TRIMMER           APPARATUS AND METHOD                 Abstract Of The Disclosure The food product sensor and trimmer apparatus and method may be used to detect and remove defects from french fried potato strips or other elongated food products as they are conveyed in separate channels on a conveyor belt.  Such apparatus comprises a defect sensor for each channel including a plurality of light detectors which detect two different wavelength light bands, such as visible light and infrared light, reflected from the surface of the food product to determine the length of the product, the size of the defect and the position of the defect on the product.  Visible light and near infrared light are reflected from the product and sensed by different detectors and the ratio of detected visible light to infrared light determined to detect defects and locate them relative to the opposite ends of the product.          An improved cutter is employed in each channel to remove the defects from the article including a single pivoted knife blade and a control means for reciprocating such blades back and forth across the path of the product so that the blade is capable of making two or more cuts per product.  The spacing between such cuts is adjusted by the control means to remove defects of different length with less waste when they occur in the middle of the product.          The control means for each cutter includes a data processor circuit receiving data input signals from the sensor means associated with such cutter.  The knife blade is pivoted by air cylinders operated by a spool valve which is moved in response to actuation of one of a pair of solenoid valves convected to the opposite ends of such spool valve and actuated by a cutting signal produced by the data processor.

Abstract: ARRANGEMENT FOR ROUTING DATA PACKETS       THROUGH A CIRCUIT WITCH            Abstract Disclosed is arrangement for routing data packets designated for a particular destination from a packet switch through a circuit switch.  The packet switch includes a plurality of output links connected to the circuit switch and a memory for designating a number of these output links for use to a particular destination.          The circuit switch has a plurality of channels to the particular destination and a switching network for connecting an equal number of the multiplex channels to the designated output links,  Included in the arrangement is a circuit allocator that monitors the use of each output links designated for use to a particular destination.  When the overall use of the designated output links is greater than an upper threshold, the allocator causes the packet switch to increase the number of links designated for use to the particular destination and subsequently causes the circuit switch to correspondingly increase the number of channels connected to the designated output links.  The number of designated output links is similarly decreased when the overall use of the output links falls below a lower threshold.  A predetermined algorithm is used to determine the upper and lower thresholds for each number of designated output links.  (FIG. 1)

Granted: 1989-02-21
Abstract: ABSTRACT The invention concerns a reciprocating pump for liquid substances, spec-ifically such contaminated by solids. To render such a reciprocating pump self-cleaning, it is suggested to arrange the intake chamber (7), pressure chamber (2), and the pressure chamber (8) side by side in a horizontal or only slightly declining plane, to arrange the check valves (9, 10, 11, 12) side by side in the same horizontal or slightly declin-ing plane, and to have the pressure socket (20) empty on the bottom side of the pressure chamber. In addition, the intake socket (19) empties suitably from below, vertically or at least steeply rising, into the intake chamber. This design ensures that the paths within the pump ex-tend essentially horizontally or only slightly upwardly, so that any solid particles which have proceeded into the pump housing can be car-ried out of the pump again.
