Abstract: A system for measuring a plurality of characteristics of a user's oral regions comprising, in combination, a pair of planks each having a proximal end and a distal end. The rods include an upper plank and a lower plank with a hinge coupling the distal ends of the rods. A pair of proximally extending supports each having an exterior surface adapted to be received in the mouth of a user. A deformable pneumatic bulb is positioned between the planks adjacent to the proximal end thereof. A associated tube thereby applies a pneumatic force to the second end of the tube. A meter is coupled to the second end of the tube to provide readings in response to the force applied to the bulb. The tube extends through a hole in the upper plank.

Abstract: A portable power distribution system for distributing electrical power under low light, emergency conditions is disclosed herein. The system generally comprises a plurality of power distribution cables, a plurality of power outlet blocks, each of which is connectable to one of the power distributing cables, wherein each block has at least one electrical receptacle on a first side, and a resilient, water-tight housing that is curved on a second side opposite to the first side and which includes a weight for gravity-biasing the receptacle away from a skyward, water-collecting orientation, and a plurality of connector assemblies, each of which has matable male and female connectors for interconnecting the power distribution cables and the power outlet blocks. Each of the male and female connectors has a resilient housing preferably integrally and solidly formed from an elastomeric material for forming a shock and water resistant covering around its conductive member.

Abstract: Vulcanizable rubber formulations will contain, as an inhibitor therefor, a compound having the formula: ##STR1## in which R and R' are independently selected from the group consisting of alkyl of from 1 to about 6 carbon atoms, cycloalkyl having from 3 to about 8 carbon atoms, phenyl and tolyl radicals. The aforesaid rubber formulations are exemplified by a styrene-butadiene rubber containing bis(N-methyl-p-toluenesulfonamido)sulfide.

Abstract: Novel compounds for inhibiting the premature vulcanization of vulcanizable rubber formulations comprising bis-(sulfonamido)-sulfides or polysulfides having the formula: ##STR1## where R and R' are independently selected from the group consisting of aryl, alkyl, cycloalkyl or substituted derivatives thereof and x is an integer of from 1 to 3. These novel compounds may be exemplified by bis-(N-methyl-p-toluenesulfonamido)-disulfide.

Abstract: Novel compounds comprising substituted thiophosphoramides, as exemplified by N-cyclohexylthio-N-phenyldiethylphosphoramide, may be used to inhibit the premature vulcanization of vulcanizable rubber formulations.
