Title: Abatement of hydrolyzable cations in crude oil
Inventor: LINDEMUTH PAUL M
IPC: B01J20/26
Filed: 1996-03-26
Abstract: Hydrolyzable cations contained in crude oil are removed from crude oil by treatment of the crude oil with an aqueous solution containing 100 to 5000 ppm of a water soluble anionic polymer containing at least 20 mole percent mer groups from the group consisting of acrylic acid, methacrylic acid, sulfomethylated polyacrylamide, aminomethanephosphonic acid modified acrylic acid and their water soluble alkali metal and ammonium salts. By removing the hydrolyzable cations, corrosion occurring on metal surfaces in contact with the treated oil during subsequent refining is reduced.

IPC: G07F17/32
Filed: 1994-12-01
Abstract: Gaming apparatus including a series of rotatable reels having indicia on the peripheries for displaying game results and which are set in motion when the game commences and which stop when the game ends. The gaming apparatus includes a number of computers for controlling the various functions such as the acceptance of a coin inserted into the apparatus, pay out of coins when a game is a winner, the commencement and termination of rotation of the reels, and the determination as to whether a game played is a winning game or a losing game. One of the computers includes a random number generator which generates a first random number that is compared to the hit frequency defined as the probability of a game being a winning game to determine whether the game played is a winner or a loser, and if the game is a losing game, the reels are stopped to display a losing combination. If the game is a winning game, a second random number is generated which is compared to the win probability set to determine the value of the win, and the reels are stopped at positions indicating a winning combination corresponding to the value won.

Title: Process for extracting pure, coarse grain silicic acid crystals
Inventor: GLASNER ALFRED
IPC: D21C11/10
Filed: 1994-12-22
Abstract: In a process for extracting coarse grain silicic acid from the spent lye to be burned from a process for extracting cellulose from annual plants, the pH value of the alkalised spent lye, which is equal to 11, is gradually reduced below 10, in particular 9. The resulting lignin is washed out and the silicic acid is largely fed back upstream of the first crystallisation stage (2) for inoculation purposes. The fine crystals are dissolved and the coarser crystals are recrystallised and further enlarged. The excess silicic acid to be recorered is preferably discontinuously removed and washed once again. The silicic acid is washed during sedimentation, for example by using desilified spent lye to reduce its water content.
