Abstract: A quick-release adaptor for a tool for a torque limiter is provided. The quick-release adaptor has a housing having a first opening at a first end and a second opening at a second end. The first opening engages a drive shaft of the torque limiter to axially and rotationally connect the drive shaft to the housing. The second opening receives the tool. A groove is provided on an exterior of the housing between the first end and the second end. At least one through hole extends through the groove and into an interior of the housing. A ball bearing is seated within the through hole. A spring clamp is provided in the groove and extends over the ball bearing to exert a radially inward force on the ball bearing to seat the tool.

Abstract: A torque limiter assembly is provided and has a fixed torque member having a plurality of first retainers, a floating torque member having a plurality of second retainers, a plurality of torque transfer members between the first torque member and the floating torque member, and a shaft. A plurality of longitudinal transfer members are provided between the floating torque member and the shaft. The longitudinal transfer members rotationally fix the floating torque member to the shaft, but allow axial movement of the floating torque member. A spring member provides a force on the floating torque member to, at times, rotationally fix the floating torque member to the fixed torque member. A locking mechanism is used to adjust the force of the spring member on the floating torque member.

Abstract: In the preparation of ethylene glycol by reacting methanol, formaldehyde and an organic peroxide, improved yields of ethylene glycol are achieved by the reaction of portions of the total amounts of formaldehyde and peroxide to be reacted with methanol. Formaldehyde and peroxide are incrementally added to a liquid medium containing methanol in controlled amounts during the reaction to permit conversion of each portion of said formaldehyde and peroxide reactants prior to the next addition. The portions are added such that the concentration of glycol in the reaction medium to which a later portion is added is greater than that to which an earlier portion is added. The reaction is continued until all the formaldehyde and peroxide has been incrementally added to the reaction medium and subjected to reaction conditions for a suitable period of time.

Abstract: Ethylene glycol is prepared by reacting methanol, formaldehyde and from greater than 6 to about 25 weight percent of an organic peroxide in the presence of about 0.5 to about 35 weight percent of water based on the feed composition, the amount of water within said range being correlated with the peroxide content. The organic peroxide has the formula R--O--O--R.sup.1 wherein R and R.sup.1 are each an alkyl or aralkyl group having 3 to 12 carbon atoms.

Abstract: Ethylene glycol is prepared by reacting methanol and an organic peroxide of the formula R--O--O--R.sub.1, wherein R and R.sub.1 are each an alkyl or aralkyl group having 3 to 12 carbon atoms, in the presence of a minor amount of a basic material. Preferably, formaldehyde is present as a reactant in the presence of water. The presence of the basic material reduces the hydrogen ions which are formed and thus reduces the amount of methylal produced.

Abstract: Ethylene glycol is prepared by reacting methanol, formaldehyde and no more than 6 weight percent based on the feed composition of an organic peroxide in the presence of water. The organic peroxide has the formula R-O-O-R.sup.1 wherein R and R.sup.1 are each an alkyl or aralkyl group having 3 to 12 carbon atoms.

Abstract: A process for the industrial production of ethylene oxide and an aromatic acid by reacting oxygen with ethylene and a methyl aromatic compound in the liquid phase. Oxygen and ethylene are passed into a liquid mono or poly methyl aromatic compound and reacted therein to produce ethylene oxide and methyl aromatic oxidates. The aromatic oxidates are then further oxidized to produce aromatic acids. When the methyl aromatic compound used is toluene the acid produced is benzoic acid, from p-xylene, terephthalic acid is produced; from m-xylene isophthalic acid is produced; and from pseudocumene (1, 2, 4 trimethyl benzene) trimellitic acid is produced.
