Abstract: ABSTRACT OF THE DISCLOSURE       The conversion of an analog signal vary over a wide dynamic range, to digital form is accomplished by integrating the analog signal and, simultaneously therewith, integrating in a sense opposite that of the analog signal a reference signal of sufficient amplitude, to maintain the stored charge within the integrator at a relatively low nominal value.  This is accomplished by placing comparators on the output of the integrator which function to cause a counter to count up or down in accordance with the relative amplitudes of the analog and reference signals as is neces-sary to bring the stored charge in the integrator back to the low nominal value.  The output of this counter is applied to a range decoder which applies selected geometrically varying ranges of digital signals to a digital to analog converter.  The output of the digital to analog converter is applied both to the subtracting or negative input of the integrator, and also provides a reference signal for the comparator.  By controlling the time period of each integra-tion and counting the amount of stored energy removed from the integrator, the counter output which is related to the such removed stored energy, is the digital equivalent of the analog signal.

Title: Process for the "in-situ" fluorination of a  catalyst
Inventor: LADEUR PETER
IPC: C10G35/06
Filed: 1979-04-26
Granted: 1982-12-07
Abstract: A B S T R A C T       Rapid in situ fluoridation at elevated temperature and pressure of hydrotreating catalysts with gaseous organic fluorine compounds, e.g., difluoroethane is disclosed. The fluorine com-pound is injected all at once in a gas preferably hydrogen, which is recycled through the hydrotreating plant. The gas is recycled until analyses on concentrations of a decomposition product of the injected fluorine compound, e.g., ethane, in the recycling gas indicates that the desired amount of fluorine has been incor-porated on the catalyst. This process provides an even distribu-tion of the fluorine on the catalyst, and permits the use of rela-tively low temperatures.

Abstract: PREPARATION OF MONOCALCIUM PHOSPHATE AND PHOSPHORIC ACID                    ABSTRACT OF THE DISCLOSURE         Monocalcium phosphate, phosphoric acid and/or potassium phosphate containing fertilizers are produced in a process involving acidulation of phosphate rock with phosphoric acid in the presence of added silicon dioxide and potassium ion whereby fluorides contained in the rock are converted to K2SiF6, wherein monocalcium phosphate dis-solved in phosphoric acid is formed during acidulation.  In an important feature, the K2SiF6 is separated and hydrolyzed to regenerate the K20 from K2SiF6 as recycled KH2P04/H3P04 solution for further reaction with fluoride from fresh phosphate rock feed.  A portion of the MCP/H3P04 solution and/or crystallized monocalcium phosphate can then be reacted with potassium sulfate, potassium bisulfate, or mixtures thereof, to form KH2P04, or KH2P04/H3P04 solutions, and gyp-sum.  In a closely related embodiment, the remaining MCP/H3P04 solution is reacted with sulfuric acid to produce phosphoric acid product and/or the recycle phosphoric acid required in the phosphate rock acidulation step.

Abstract: Harry W. Skinner Alan D. Burdick GASKET APPARATUS AND METHOD                 ABSTRACT OF THE DISCLOSURE     This invention relates to a gasket apparatus for providing a fluid tight seal between a pipe and a porthole in the wall of a manhole riser.  The apparatus includes an elongated sleeve of elastomeric material, The sleeve having at one end an outwardly turned, reflexly curved annular flange.  The body portion extends axially beyond the flange.  A rigid reinforcing ring coaxially engages the inner surface of the flange, forming said flange to a predetermined outside diameter.  This apparatus is inserted into the porthole in coaxial sealing relationship therewith.          The flange is radially compressed between the ring and the wall of the porthole thereby providing a seal.  The end of the pipe is received by the sleeve which is clamped at the digtal end thereof onto the pipe to provide a further seal.    The method of forming the seal includes inserting a solid, substantially rigid ring into the end portion of an elastomeric elongated sleeve which thereby determines the outer diameter of the sleeve radially opposite the ring.  The assembled ring and sleeve are inserted edgewise into the hole in a direction substantially parallel to the axis thereof with the assembled ring and sleeve lying in a plane also substantially parallel to this axis.  The assembly is then forcefully rotated until it is coaxially positioned within the hole with the sleeve material being radially compressed between the ring and the wall of the porthole.

Inventor: KNOWLES ALVIS R
IPC: B23K3/02
Filed: 1979-09-27
Granted: 1980-08-26
Abstract: ABSTRACT OF THE DISCLOSURE           A soldering iron can be constructed using a heating element structure or first part connected to a handle structure or second part through the use of connec-tors on these parts which are adapted to be secured together through the use of a rotary or twisting type motion.  The handle structure includes a spring biased sleeve which projects from it toward the heating element structure. The heating element structure includes a metal flange which is resiliently engaged by the sleeve when the parts are connected together.  This flange in effect forms a part of a tubular, metal housing used to connect a body disposed in proximity to the heating element so as to conduct heat away from the heating element and the connector on the heating element structure.  The housing serves to protect the heating element structure against physical damage and is grounded through the flange and the sleeve to an appropriate grounding wire leading from the handle structure.

Abstract: ABSTRACT OF THE DISCLOSURE This invention provides a process for preparing 2-(3-aryl-5-isoxazolyl)-benzoic acid having the formula wherein X and Y are independently selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, halo-lower-alkyl, phenoxyphenyl and cyano which comprises heating 3'-(aryl)spiro[isobenzofuran-1(3H),5'(4'H)-isoxazol] 3-one having the formula at a temperature ranging from 30°C. to the reflux temperature of the solution. The compounds obtained are effective as plant growth regulants. The process of the present inven-tion overcomes disadvantages associated with prior art processes which involve the conversion of isoxazolin-5-yl benzoate with N-bromosuccinimide or dichlorodicyanobenzo-quinone since isoxazolin-5-yl benzoates are prepared from vinyl benzoates which are difficult to prepare.

Abstract: ABSTRACT A pill dispenser is provided to enable individuals to take medication at regular specified times throughout the day. The dispenser has an open container with a divider means having a plurality of compartment-forming walls which divide the container into a number of compartments, each compartment adapted to receive and store medication to be taken at a prescribed time as identified with an hour label associated with the compartment, and a rotatable cover enclosing the container and having a sector-shaped opening, which can be moved over a selected compartment for the removal of the medication contained therein. If all compartments are used for holding medication, the sector-shaped opening may be covered with a closure tab which is openable so that the first dose of medication can be taken at the first prescribed time. The divider means may be detachably secured in the container so that it can be replaced with another divider means having a larger or smaller number of compartment-forming walls to thereby accommodate different dosage time periods. The assembly of the dispenser components may be achieved with a separate securing means or the components may be constructed in a particular way without using separate securing means.
