Abstract: ABSTRACT          PROCESSING METAL CHLORIDES    Metal may be recovered from metal chlorides, for example a mixed metal chloride residue from the fluid-ised bed chlorination of a titaniferous ore in the presence of carbon to produce titanium tetrachloride by heating, in the presence of a scavenging agent, which may comprise a combination of titanium dioxide and carbon inherently present in a residue from the aforesaid fluidised bed chlorination process, to at least 1500°C and preferably to a temperature at which iron present is liquid.  If the temperature is maintained at below 2200°C iron,vanadium and niobium may be recovered preferentially to certain lower value metals which remain in the form of chlorides giving the possibility for the recovery of a high value mixed metal product.  Titanium trichloride may be formed and this may be chlorinated to titanium tetrachloride thereby increasing the efficiency of the original chlorination process.

Abstract: ABSTRACT OF THE DISCLOSURE            A nut running tool of the non-impacting type is dis-closed for transmitting controlled torque to a driven article.          The tool produces a succession of torque pulses which provides a relatively small degree of reaction torque returned to the operator as compared with a high degree of torque delivered to the article.  The tool has a pulse torque transmitting air motor comprising a liner defining a rotor chamber, a rotor supported in the chamber for relatively angular movement, a single blade co-extensive with the rotor projecting radially from the latter into bearing relation with a cylindrical wall of the chamber, and means for causing live air to be alternately admitted and vented from areas of the chamber at opposite faces of the blade so as to cause the rotor to oscillate forwardly and reversely about its axis.

Abstract: ABSTRACT The invention relates to polymeric alloys of rod-like and coil-like aromatic heterocyclic polymers useful for the fabrication of high strength load bearing struc-tural components.  In one aspect of the invention, rod-like aromatic heterocyclic polymers are used as reinforce-ment in coil-like heterocyclic polymer matrices to pro-vide  composites at the molecular level that are analogous to chopped fiber composites. A representative example of the coil-like heterocyclic polymer consists essentially of repeating units having the following structural formulas:                                           _  or   wherein X is NR, N? , O or S, where  ? is phenly, Ar' in                             or        ,    and m is an integer having a value such that the polymer has an intrinsic viscosity of about 2 to 20 dl/g as determined in methanesulfonic acid at 30°C, and a representative example of the rod-like aromatic heterocyclic polymer consists essentially of repeating units having the following structural formulas:                           or   wherein X is NR, N? , 0 or S, where ? is phenyl, Ar is                 and n is an integer having a value such that the polymer has an intrinsic viscosity of about 5 to 30 dl/g as determined in methane-sulfonic acid at 30°C.

Title: Preparation of formic acid by hydrolysis  of methyl formate
Inventor: LEONARD JACKSON D
IPC: C07C51/09
Filed: 1979-06-04
Granted: 1981-12-15
Abstract: ABSTRACT OF THE DISCLOSURE        Formic said is produced in a continuous process by hydrolyzing methyl formate with water at high temperature and pressure in the presence of a formic acid catalyst.          Methanol is also formed.  The reesterification of the reaction products to methyl formate (a reaction favored by high temperatures) is minimized by flashing the reaction product at relatively low pressure and temperature and thereafter distilling the residual liquid under vacuum.          This procedure separates the methyl alcohol from the formic acid with a minimum contact time and at a low temperature which does not favor the reesterification reaction.  The flashed vapor, primarily unreacted methyl formate, is recycled to the reaction zone.  High purity formic acid, i.e., 85%, is obtained by subjecting the bottom from the vacuum distillation to a second distilla-tion step.  The distillate from the vacuum distillation is distilled to separate residual methyl formate for recycle from the co-product methyl alcohol.       In another embodiment of the invention, prior to the main hydrolysis, the methyl formate is partially hydrolyzed to form the small amount of formic acid needed to accelerate the main hydrolysis step.  Accordingly, the necessary formic acid catalyst is formed eliminating the need to recycle product formic acid.

Abstract: INTERPERSONAL-INTRODUCTION SIGNALLING SYSTEM          Abstract of the Disclosure An interpersonal-introduction signalling system includes a receiving and transmitting transceiver having a relatively short range response and of such size as to permit convenient carrying by a person.  A code system defines a plurality of categories, each of which has a particularly identifiable characteristic.  Each person carrying a similar receiving and transmitting transceiver can select a particular code to send and a particular code to accept, such that designated information is transmitted and/or received.  When accepting a signal or information, a different signal is sent by the receiver to indicate the acceptance to the person transmitting.  The transceiver includes an indicator to alert the receiving person and indicate the necessity of transmitting a response.  Thus, the encoding permits the several persons involved to define the different categories of persons having selected unique characteristics for contact.
