Abstract: Abstract of the Disclosure The invention concerns a motor-driven screwing and transporting tool for tightening or loosening the threaded studs and associated tighten-ing nuts of the head bolting of pressure vessels.  After the tightening nuts are loosened or before they are tightened, the weight of the studs is taken over by rotating bearings that can be lifted, so that the studs with their tightening nuts can be screwed in or out, the screw threads of the studs being thus weight-relieved.  The invention is intended primarily for nuclear reactor pressure vessels.

Abstract: METHOD AND APPARATUS FOR DEPOSITING FILM ON A SUBSTRATE, AND PRODUCTS PRODUCED THEREBY Method and apparatus for using emitting, ionizing J accelerating and collecting elements in a high vacuum to implant a hard film on a plastic substrate or the like.  In preparation, a slug of selected material to be deposited as a film is placed in the emitter.  The specimens or articles to be implanted are placed on supports in the vicinity of the collector.  A cover enclosure is then placed in position and the region enclosed by the cover is exhausted to a high vacuum.  Selected potentials are applied to various elements of the apparatus and an accelerating/directing field, which may be developed electrostatically, magnetically or by a combination of both, is developed in the acceleration structure.  The electrostatic field causes electron emission from the ionizing elements to develop an increased charge on the emitted ionized particles.  When implantation is to begin, a shutter control is moved out of beam blocking position and ionized particles from the emitter pick up additional charge from the ionizing elements and are accelerated to high velocity for bombarding the specimens.  The collector is provided near the end of the enclosure beyond the specimen support region.  The specimens are discharged regularly to eliminate the build-up of surface charge from the stream of bombarding ions.

Abstract: ABSTRACT OF THE DISCLOSURE     Volatile reactants are heated under reflux in a reactor and form volatile reaction by-products which are continuously removed in a vapour effluent from a reflux column and partial condenser.  The effluent, which entrains some of the reactants, is condensed in a first total condenser and is fed to a distillation apparatus for separation of the volatile reactants and by-products and return of the separated reactants to the reactor.  Before the condensate reaches the distillation apparatus, it is temporarily stored in a receiver from which it is controll-ably fed to a pre-heater where it is evaporated and then fed as a vapour to the distillation column of the distillation apparatus for separation.  The distillation column includes at one end a reboiler which retains the reactants.  The other end of the distillation column is coupled to a second total consenser in which the volatile by-products are condensed and withdrawn through a cooler for disposal.  The reactants are controllably fed from the reboiler back to the reactor, thereby providing control of the system, which has improved efficiency since the distillation apparatus operates independently of the temperature and pressure conditions in the reactor and of the rate and composition of effluent from the reflux column.  The apparatus and method disclosed are particularly useful for the production of unsaturated thermoset polyesters, simple ester plasticizers and alkyd resins.

Title: Bridge for stringed instruments

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to a bridge for string instruments.  Many bridges available today include a plurality of bridges sections constructed as drums posi-tioned in end-to-end relationship, each string of the in-strument being conducted over one of the drums.  However, the drums are typically connected to the bridge base in a manner which permits a limited amount of axial movement of each drum.  Additionally, each drum typically has a pair of internally threaded holes extending laterally therethrough, each of the holes receiving a projecting set screw which may rub across the sleeve of the player of the instrument and damage and often ruin such sleeve.  According to the present invention, these problems are solved by providing a novel bridge for stringed instruments.  The present bridge includes a plurality of independently movable drums which permit separate adjustment of the length of each string and the height of each string relative to the neck of the in-strument thereby permitting the greatest latitude of adjust-ment possible for each string.  However, the present bridge substantially reduces the ability of the drums to vibrate, substantially increasing the tone sustaining capabilities of each string over that obtainable heretofore.  Further-more, the drums are constructed and connected to the base of the bridge in a manner which prevents loss of the set screws which are used to adjust the height of each string and which prevents damage to the sleeve of player of an instrument using the present bridge.

Abstract: ABSTRACT                Palm oil is subjected to a two-stage fractionation in a solvent free system using controlled heating and cooling to give a mid-fraction of iodine value 48-53 and melting point 32-38°C that can be used to extend cocoa butter.  In order to increase the amount of mid-fraction that can be satisfactorily incorporated into cocoa butter, the isolated mid-fraction is then either subjected to partial hydrogenation to reduce its linoleic acid content to not more than 2% or has 0.01-1.5% of a dry edible gum e.g. a mixture of guaranate and carraghenate gums, incorporated.  This gum treatment converts this particular mid-fraction into a dimensionally stable solid which can be cast or moulded and can be used to extend cocoa butter in amounts up to 30% or more without adversely affecting the Jenson cooling curve.
