  • Patent number: 9206624
    Abstract: An electromechanical cable lock system comprising an electromechanical locking mechanism including a cable having at least one plug end receivable in the locking mechanism and a plurality of slidable locking plates engageable with the plug in said locking mechanism. At least one of the locking plates is capable of movement in a first direction different from the movement of a second of said locking plates in a second direction. The locking plates are driven by a motor-driven cam mechanism. The system includes a card reader or other credential verifying device and an electronic controller for activating the locking mechanism, The system also includes a barrel lock for over-riding the electronic controller. A plurality of features can detect and alarm in the event of tampering or unauthorized entry.

  • Patent number: 3932267
    Abstract: A method for producing uninhibited transformer oil is disclosed which includes isolating a petroleum distillate that is primarily naphthenic and aromatic in character, boiling above 400.degree.F, having a viscosity between 50 and 100 SSU at 100.degree.F, and containing sulfur compounds; contacting the distillate with a solvent selective for aromatic hydrocarbons under conditions to produce a raffinate phase containing 15-30%v aromatic hydrocarbons; hydrotreating the raffinate phase to reduce the nitrogen content to at most 25 PPM, to maintain the sulfur content greater than 0.08%w, and to maintain the aromatic hydrocarbon content greater than 15%v. The product is an uninhibited transformer oil, and it can be further improved by regenerative clay treatment and by the addition of certain aromatic hydrocarbon compounds containing two or more six carbon membered fused or unfused rings, at least one of which is a benzene ring.
