Abstract: A process for the formation of a force field comprising cooling at least one crystal selected from potassium tartrate, cesium nitrate, rubidium nitrate, tartaric acid, cadmium nitrate and thorium nitrate to a temperature below about 110K. The force field comprises an electric field and a mass attraction field which maintains its intensity over long time periods. A method is also provided for establishing a force field at a location remote from the cooled crystal by means of an electrical connection to the cooled crystal by an insulated electrical conductor. The invention includes a device for forming the force field.

Abstract: This invention relates to a device for floatably guiding webs of material by means of gaseous or liquid medium. The device comprises at least one elongate flow member having a surface convexly curved on the top side proximate the web, and nozzles which are disposed in rows along longitudinal edges and via which the gaseous or liquid medium can be introduced in jets between the flow member and the web of material. The nozzles associated with one longitudinal edge of the device are offset in pitch in relationship with the other longitudinal edge and are so disposed that opposing diverging flow jets, flow past one another without mutual impedance. The apparatus operates on both the supporting airfoil and air cushion principles, with a smooth transition from one principle to another.

Abstract: This invention relates to novel organic trithio oxides of the formula:R.sup.1 --X --R--X.sup.1 --R.sup.1wherein R is selected from --CH.sub.2 CH.dbd.CH--, ##STR1## and (CH.sub.2).sub.3 ; X is selected from ##STR2## X.sup.1 is selected from --S--S, ##STR3## and, each R.sup.1 is independently selected from carboxyalkyl, alkoxy, alkylthio, amino, alkylamino and acyl substituted and unsubstituted lower alkyl, lower alkenyl, lower alkynyl, phenyl and lower alkylphenyl; provided when R is --CH.sub.2 CH.dbd.CH--, X is ##STR4## and X.sup.1 is --S--S--, then R.sup.1 is not in both instances --CH.sub.2 CH.dbd.CH.sub.2.This invention also relates to a method of preparing the above-identified compounds by heating and further oxidizing various oxides of organic disulfides and to antithrombotic uses of the compounds.

Abstract: An improved process for the production of chlorine dioxide wherein an alkali metal chlorate and a mineral acid are reacted in a single vessel, and the resultant alkali metal salt is converted to a more desirable salt in a metathesis column by reaction with an appropriate acid or an alkaline earth or alkali metal, chloride.

Abstract: A process for the chlorination of toluene comprises reacting toluene with chlorine in the presence of a catalyst system comprising a Lewis acid catalyst and a co-catalyst selected from the group consisting of diphenyl selenide and aluminum selenide. The monochlorotoluene product obtained is characterized by a substantially reduced ratio of orthochlorotoluene to parachlorotoluene.
