Title: Material edge position transducer for stamping machines - using controlled intensity light beam interrupted by edge uses LED as light source
Inventor: VESTER KLAUS
IPC: G01D5/34
Filed: 1974-12-27
Abstract: An accurate transducer for the measurement of the edge position of a opaque material is particularly suites to stamping machine applications. The transducer gives contactless edge position measurement and consists of a light beam produced typically by a LED which is interrupted by the edge of the material concerned. The beam is detected by a photosensitive device so that the beam energy is just over the detectible threshold of that device. Any variation in that energy caused by movement of the measured edge position is used to alter the beam intensity until the previous situation is restored. Measurement of the current to the beam transmitter then provides an accurate measurement of the edge position.

Title: Reduction of fluid flow friction loss in pipelines - by injection of polymers in crumb form, pref as a slurry with a non-solvent
Inventor: KRUKA VITOLD RAIMOND
IPC: F17D1/16
Filed: 1975-03-26
Abstract: Polymeric materials are injected in small quantities into flowing hydrocarbons in pipelines to serve as friction reducing agents. The polymer (pref. polyisoprene) is prepd. and injected into the pipeline as polymer crumb, pref. slurried in a non-solvent (pref. water) and pref. after dusting with a combination of 2,6-di-tert-butyl-p-cresol and 2,2'-methylenebis-(4-methyl-6-tert-butylphenol) to reduce oxidative degradation of the polymer. The particle size of the polymer crumb is about 3/8 inch dia. and requires about 2-4 days to completely dissolve in flowing crude oil. Use of polymer in crumb form aids dissolution rate in flowing hydrocarbons, (c.f. shredded or ground forms of polymer). The system avoids pre-soln. of polymer and associated degradation by shearing, and provides continuous source of dissolved polymer in flowing hydrocarbon. Use of non-solvent and/or dusting with anti-oxidant prevents significant oxidative degradation of polymer. Friction loss redn. of up to about 80% can be achieved.
