摘要： In order to increase the ''''sale'''' or ''''cost'''' registering capacity of a standard, conventional threewheel register (counter) used in gasoline dispensers, a modified price wheel has been developed as a substitute for the lowest-order price wheel of a conventional register. This new wheel carries indicia from zero to 99 and during counting makes one revolution for every one hundred cents'' worth of gasoline dispensed. The new wheel has an antibacklash arrangement for eliminating inaccuracies during the counting mode, and has an improved reset stop and a linkage mechanism associated therewith, for providing accurate resetting and for preventing improper operation during the resetting mode.

摘要： Apparatus, useful in gas-fog reaction processes, comprises, in combination as a reactor system, an electrostatic fog generator, means for feeding liquid reactant or catalyst (e.g., acid) to the generator, and means for feeding a catalyst or reactant fog from said generator to a reactor vessel, means for feeding at least one vaporizable or gas phase reactant or catalyst to said reactor vessel and means for removing liquid reaction product, unreacted gas phase feed reactant and spent catalyst or liquid reactant from said vessel. The apparatus can be useful in a process for alkylation of gaseous C2-C5 monoolefin with gaseous C4-C6 branched paraffin comprising contacting the mixed gases at alkylation conditions with a fog or mist of strong mineral acid. The apparatus can contain means for injecting a vaporizable liquid reactant (e.g., isobutane) into the reactor in order to control the reaction temperature by vaporization of the reactant.

摘要： A capacitive-type inclinometer cell, which rotates with the drill pipe, is located in a wellbore. A capacity transmitter, located downhole near the inclinometer, converts the capacity changes of the inclinometer into a rectangular wave which can be transmitted to the surface. At the surface, an electronic unit converts the rectangular wave into a voltage which can be displayed on a meter calibrated to read degrees.

摘要： An X-coordinate manifold, having a plurality of parallel channels extending in the X direction, is mated with a Ycoordinate manifold, having a plurality of parallel channels extending in the Y direction, to form a XY plane manifold. A preselected arrangement of ports, communicating with certain channels, is provided in each manifold, to thereby provide, when the manifolds are so mated, a matrix of paired, aligned ports which are located at the crossing points of certain channels in the X and Y coordinate manifolds. Also, a vertical or Z-channel is made available at the crossing points of certain channels in the X and Y coordinate manifolds. Two or more XY plane manifolds are stacked on top of one another to form a three-coordinate manifold. Gaskets used between the mated coordinate manifolds, and also between the stacked plane manifolds, act as programming devices and also serve as ball retainers for shuttle balls functioning as check valves.

摘要： A PROCESS FOR ALKYLATION OF GASEOUS C2-C5 MONOOLEFIN WITH GASEOUS C4-C6 BRANCHED PARAFFIN COMPRISES CONTACTING THE MIXED GASES AT ALKYLATION CONDITIONS WITH A FOG OR MIST OF STRONG SULFURIC ACID AND A PROMOTOR. THE PROMOTER MAY BE RED OIL OR SPENT ACID FROM A CONVENTIONAL SULFURIC ACID ALKYLATION OR FROM A PREVIOUS RUN OF THE PRESENT PROCESS. PREFERABLY, THE CATALYST AND HYDROCARBON REACTANTS ARE MAINTAINED IN A CONCURRENT FLOW. FOR C3 OR C4 ACYCLIC MONOOLEFIN AND C4 OR C5 ISOPARAFFIN, THE PREFERRED ALKYLATION CONDITIONS INCLUDE A TEMPERATURE IN THE RANGE OF ABOUT 30-80*F. AND A PRESSURE ABOUT ATMOSPHERIC (E.G., 5-25 P.S.I.A., TYPICALLY 14-20 P.S.I.A.). THE FEED MOLE RATIO, PARAFFIN TO OLEFIN, CAN BE IN THE RANGE OF 1:1 TO 60:1, TYPICALLY 2:1 TO 30:1. LIQUID PARAFFIN (E.G., ISOBUTANE) CAN BE INJECTED INTO THE REACTOR IN ORDER TO CONTROL THE REACTION TEMPERATURE. PREFERABLY, THE LIQUID ACID DROPLETS HAVE A MEAN DIAMETER IN THE RANGE OF 5-50 MICRONS, TYPICALLY 10-25 MICRONS. AN ADVANTAGE OF THE PRESENT PROCESS IS A SUBSTANTIAL SAVINGS IN DISTILLATION COSTS REQUIRED TO SEPARATE ISOBUTANE FROM THE PRODUCT.

摘要： A body of liquid contained in a ring-shaped piece of tubing serves as a liquid pendulum. Changes in the elevation angle of the support on which the tubing is mounted cause the tubing to rotate relative to the liquid; this relative rotation is sensed by means of a pair of capacitor electrodes coupled to the liquid, variations in capacitance causing energization of a driving motor in a direction to rotate the tubing back to a null position. The amount of rotation of the support, and hence the elevation angle, is indicated on a digital voltmeter supplied from a potentiometer mechanically coupled to the shaft which rotates the tubing.
