Title: Method for manufacture of chitosan and other products from shells of organisms, especially marine organisms
Inventor: STRUSZCZYK HENRYK
IPC: C08B37/08
Filed: 1990-10-19
Abstract: The invention relates to a method of manufacture of chitosan and other products, such as chitin and proteins, from the shells of organisms, especially marine organisms, as a result of the reaction stages of deproteinization by alkaline solutions, demineralization by acidic solutions and deacetylation by concentrated alkaline solutions. The method comprises at least two successive stages of said three stages. The chitosan is manufactured so that in the shells of organisms, especially marine organisms, such as crabs or shrimps, are placed in a space in a reactor limited by a wall pervious to reaction liquids but retaining said shells of organisms. Thereafter they are subjected to a continuous action of reaction liquids, especially in a recirculation system flowing through the reactor and said space. After every reaction stage the solid product obtained is optionally washed by water using a continuous flow of water through the reactor to remove the residual reaction liquids. Thereafter the solid end product is optionally dried, preferably in an air flow at a temperature of 40-100 ·C.

Inventor: MANSHIP JON
IPC: A63F13/45
Filed: 1992-12-15
Abstract: A video slot machine includes a display screen on which the wheels of a slot machine are simulated.  The display screen is divided into an array of cells with each cell displaying an individual game element selected randomly from a group of available game elements during a game play.  Pay-out lines are associated with the rows, columns and diagonals of the array of cells and visually indicate some of the pre-determined sets of cells which are examined to detect winning combinations of displayed game elements.  Pay-out tables are stored in memory within the machine and hold information concerning combinations of game elements in all of the pre-determined sets of cells which result in a win when displayed on the screen together with the amount to be paid for each winning combination of game elements. When the game is played and the screen displays a randomly selected game element in each of its cells, the machine consults the pay-out tables to determine if the game elements as displayed in the cells result in a winning combination of game elements as stored in the pay-out tables and calculates the amount to be paid. Therefore, depending on the elements displayed in the array of cells, winnings from more than one pay-out table may result.  The winning combinations of game elements, the pre-determined sets of cells, the number of available game elements and the amount paid for each winning combination of displayed game elements are selected so that the expected return of the video slot machine complies with regulatory restrictions while still ensuring that the game is dynamic and appealing to a player.

Abstract: A rifle sling for steadying the left arm of the shooter, comprises a length of band or strap material (1) which has an upper arm loop (8) at one end and a hand loop (6) at the other end, said loops being inter-connected by a middle portion. The upper arm loop (8) has a double portion extending between a tightening buckle (2) and an adjustment buckle (3). By using these buckles to adjust the length of the double portion, both the upper arm loop (8) and the middle portion of the sling can be adjusted to fit the shooter. The sling may be worn in a non-operable condition with the upper arm loop (8) tightened around the upper arm of the user and with the hand loop (6) tucked in under the upper arm loop.  When assuming a shooting position, the user loosens the hand loop (6) and puts his four fingers through the loop, thus tensioning the middle portion of the sling and steadying his arm while the fore-end of the gun rests in his palm. Since the sling is at no time attached directly to the gun, the sling is particularly suitable for hunters.
