Title: Strain-gage transducer bridge gages with integral  calibration resistors
Inventor: SPOOR MARTIN
IPC: G01L1/22
Filed: 1980-01-07
Granted: 1982-01-05
Abstract: ABSTRACT OF THE DISCLOSURE     Each of two pairs of electrical-resistance strain gages which are to make up a measurement bridge for a beam-type load cell is fashioned as a composite wherein two spaced-apart grids of foil-type parallel elongated filaments oriented and function-ing as strain gages are made of material promoting a strain gage factor effective to compensate for elastic modulus change of the beam material as temperature varies over an expected range.  In-termediate the two grids of strain-gage filaments, where a neutral position between tension and compression surface strains of the sensing element of a gaged beam may be expected to appear, the common insulating backing for the two grids carries a set of nar-row strands which produce a dummy foil resistance of predeter-mined value needed for a calibration wherein it simulates the influence upon bridge input impedance of a temperature-compensation resistance such as would otherwise be used without the inherent compensation for elastic modulus changes by way of offsetting effects of strain gage factor of the gages.  The same material which forms the foil or printed-circuit type gage grids also forms the dummy or calibration resistor upon the same under-lying backing, and, in addition creates relatively large-area and low-resistance integral interconnections between the gages and resistance and tabs for needed external-wiring connections.

Abstract: TITLE OF THE INVENTION        XANTHAN GUM-MODIFIED STARCHES            ABSTRACT OF THE INVENTION      A novel form of starch (e.g., root, root-like, cereal, or blend thereof) modified by xanthan gum is disclosed.  The xanthan gum-modified starches exhibit properties similar to those of chemically-modified pregelatinized starches. Xanthan gum-modified starches are characterized by increased acid stability, by heat and shear stability, and by increased resistance to disso-lution in aqueous media.  The novel process by which this novel starch is made comprises:  heat-ing to gelatinize an aqueous starch-xanthan gum blend below 100°C, continuing heating to reduce the moisture content to about between 5 and 10%, then further drying the mixture (typically to below 7% moisture) above 100°C long enough to cause interaction between the starch and xanthan gum.  Drum drying is the preferred heating method that combines the heating and drying steps.

Abstract: PROCESS AND DEVICE FOR MODULATING THE PHASE OF THE WAVES TRAVELING IN A RING INTERFEROMETER            ABSTRACT OF THE DISCLOSURE   Procedure consisting in inserting along the ring of a ring interfero-meter at least one reciprocal-effect phase modulator.   The .PHI.(t) function, representing the modulation of the phase of the two waves traveling in opposite directions in the ring of the interferometer, is a periodic function confirming the relationship .PHI.(t) = .PHI.(t + 2?), where ? is the time which electromagnetic waves take to travel round the ring.   The effect of this modulation is to shift the measuring point on the curve representing the optical power depending on the variation of the phase difference  .DELTA.? between the two waves and to obtain a maximum sensitivity of the measurement about the point (.DELTA.?) = 0 by making the power component detected, representing the magnitude to be measured, proportional to sin (.DELTA.?).   A control signal generator supplies simultaneously these signals to the modulator and to a synchronous detector.

Abstract: ABSTRACT      A burner for the partial oxidation of pumpable slurries of solid carbonaceous fuels in which the pumpable slurry of solid carbonaceous fuel in a liquid carrier is passed in liquid phase through one passage of a burner comprising a retracted central coaxial conduit, an outer coaxial conduit with a converging orifice at the downstream tip of the burner and, optionally, an inter-mediate coaxial conduit. The downstream tips of the central conduit and the intermediate conduit, if any, are retracted upstream from the burner face a distance of respectively two or more say 3 to 10 for the central conduit, and about 0 to 12 say 1 to 5 for the intermediate conduit times the minimum diameter of the converging orifice of the outer conduit at the burner tip. A pre-mix zone is thereby provided comprising one or more, say 2 to 5 co-axial pre-mix chambers in series. The free oxygen-containing stream is passed through a separate passage of the burner into the pre-mix zone, in which mixing takes place with the slurry of solid carbonaceous fuel and liquid carrier. From 0 to 100, say about 2 to 80, volume % of the liquid carrier may be vaporized in the pre-mix zone. The multiphase mix-ture of reactants is then discharged into the reaction zone of the free-flow partial oxidation gas generator by way of the converging orifice of the outer conduit at the burner tip. Synthesis gas, fuel gas, or reducing gas is thereby produced.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is an apparatus and a method for heatless production of hollow items, such as foundry shell cores from the mixture of granular mineral and synthetic binder, as provided by the principal process described in the U.S. patent application Serial No. 022,170, now U.S. Patent No. 4,232,726 issued November 11, 1980.  Two permeable-to-gas patterns form an inner cavity of desirable configuration and are enclosed by non-permeable halves of the pattern box, forming an outer cavity or flow space.  The pattern box is mounted on two plates Or the rotatable cage assembly, selectively positionable in at least three positions: charge, discharge, and transfer.  Above the pattern box are pivotally mounted material supply means, sealing means, and a trimmer.  Below the pattern box is a receiver of an airless con-veyor for recirculation of the discharged unhardened material. The pattern box is connected to two manifolds:  one for consecu-tive supply of catalyst gas and the compressed air, another for exhaust and venting.  After material  has been blown with the help of compressed air from the material supply means into the pattern inner cavity, it is sealed and the air is flushed out of the system by compressed catalyst gas introduced into the pattern box fox about one second.  Said gas then penetrates to desirable depth into material's outer layer starting polymerization and curing of its binder.  After a few seconds, unsealed pattern box assembly is turned upside down and compressed air is blown into the pattern box, dislodging unhardened portion of the material out of the inside of the produced shell-like product.  Conse-quently, the pattern box is opened and the product is transferred from the apparatus to a suitable place outside the machine.  The production process has nine basic steps, and the cycle of the apparatus comprises twenty-four (24) operations completely mechanized and performed within approximately thirty seconds.

Abstract: ABSTRACT:               An apparatus for the repair of rubber or plastics conveyor belts, usually having reinforcement inserts, and for making them endless. The basic components of the apparatus are press plates which can be heated, upper girders, lower gliders and hydraulic pressure-producing equipment. The girders are connected together in pairs by tensioning bolts with mechanical tightening facilities. The girders undergo bending deformation under a specified pressure, with a defined deflection curve or bending line. The pressure-producing equipment acts between one of the press plates and the associated girders, and consists of hydraulic tubes which are of constant perimeter but the cross-section of which can be deformed. The tubes are supported one one side by the associated girder, and on the other side on a pressure plate constructed with a U-profile. The distance of the pressure plate from the associated girder is adjustable and is so adjusted that in the operating condition the hydrau-lic tubes posses an oval cross-section. Conse-quently they can act as pressure-producing equipment, although constructed as hydraulic tubes of constant perimeter.  The deflection of the girders can be compensated by a deflection curve compensator.
