Abstract: Processes for preparing dibutyl ethers from 2-butanol using an ionic liquid.

Abstract: The present invention relates to a catalytic process for making dibutyl ethers using a reactant comprising isobutanol and water. The dibutyl ethers so produced are useful in transportation fuels.

Abstract: The present invention relates to a process for making butenes using dry 1-butanol obtained from fermentation broth. The butenes so produced may be converted to isoalkanes, alkyl-substituted aromatics, isooctanes, isooctanols, and octyl ethers, which are useful in transportation fuels.

Abstract: A pin-type punch having an arm pivotal on a base in which the punch pins for punching sheets of paper are located on the arm or on the base and die holes on are located the opposite part. To create alignment of pin-to-hole, one or the other is mounted on or is in a floating unit. Each unit is caused to float by being positioned by engagement of punch alignment pieces just prior to the pins passing through the paper into the die holes.

Abstract: An improved security system for preventing the theft of items, such as typewriters and personal computers. The system has a security plate which is fixed to the item that is to be secured. A bendable member is permanently attached to a center area of a plate base, and has a free end spaced from the center area of the base. A loop is advantageously formed on the free end for attaching the bendable member to a cable, chain or the like used to attach the plate to the anchor. When an attempt is made to forcibly remove the item, the bendable member bends to direct the removal force to the center of the plate where it can be distributed over the entire base and thereby more effectively resisted.
