Patent EP-0312642-A1 (EP)
Inventor: OTT WALTER H DR
IPC: B01F5/00
Filed: 1987-10-23
Abstract: A method for introducing gas into water in excess quantity relative to an equilibrum condition corresponding to the satura­tion of water with the gas on any predetermined temperature and pressure, in which the water is intensively moved and circulated to form an intensive vortex which resembles to the form of the funnel of a tornado and the free surface of this funnel is ex­posed to the gas. The, circulation is mainatained for a while, at least as every water particle has entered and left the vortex 100 times. 
     An apparatus for carrying out the method comprises a bal­loon-like conatainer (1), with a tapering lower part (4) and an oblique and tangential inlet duct (13) somewhat below the plane where the container (1) has it largest diameter. A feedback cir­culation path including a pump (14) and a resonator (15) is pro­vided between the lower end of the container (1) and the duct (13). The resonator (15) forces the water flowing therethrough to rotate in a plane normal to the direction of flow. The so in­jected water forms a vortex in the container above which gas, preferably oxygen or carbon-dioxide is present which will be ta­ken up by the water. 
     The water made by the method comprises a gas in excess quan­tity relative to the equilibrum condition in such a way that the gas contained therein is in a stable and bound state.

Abstract: Substituted N-methylisoxazolidines of the formula (I) <IMAGE>  in which R<1> represents alkyl, cycloalkyl, aryl or heteroaryl which are each optionally substituted, R<2> and R<3> independently of one another each represent hydrogen, or substituted alkyl, alkenyl, cycloalkyl or aryl which are each optionally substituted, or together with the nitrogen atom to which they are bonded, represent an optionally substituted saturated heterocycle which may optionally contain further hetero atoms, and their acid addition salts, and their geometrical and optical isomers and isomer mixtures, and their use in pesticides. The novel substituted N-methylisoxazolidines of the formula (I) can be prepared by known processes, for example by reacting suitable nitrones with suitable alkylamines or suitable isoxazolidines with suitable amines and also by alkylating suitable substituted N-methylisoxazolidines.

Abstract: In a device (1) for the raising, lowering and horizontal transport of cars (2), eight gripper arms (14 to 21) respectively arranged vertically in pairs and bent approximately at right angles at their lower end are mounted pivotably, rotatably and displaceably on an adjustable support (11), and, in the transport position, a wheel (3) of the car (2) is locked by being surrounded at the front and rear by each pair of gripper arms (14, 15 or 16, 17 or 18, 19 or 20, 21). This design makes it possible, in a small amount of space, to place empty cars of differing size close to one another on a parking area and to pick them up again, so that the number of cars to be parked is increased considerably for the same size of parking area. Traffic areas for getting out of and into the cars and for approaching the parking area are not necessary and the gripper device (1) takes up only a small amount of space. <IMAGE>

Abstract: For covering hitch balls on the hitch systems of cars a loose covering hood is usually used, which is placed over the hitch ball (6) and which may easily be lost if it is loose, or create noise if it is suspended in a chain, when the ball is being used. By the invention is provided a covering hood by means of two semi-spherical shells (24) which are pivotally fastened to the hitch rod (4) right below the hitch ball (6), such that they are pivotal from a covering position closed about the hitch ball to oppo­site projecting positions, in which the hitch ball is uncovered. On already existing hitch systems the shells (24) are easily mountable by means of a simple clamp fitting, which is even well suited to be fixed on a conical hitch ball rod.

Abstract: A reprogrammable logic fuse (RLF) based on a 6 device standard Static Random Access Memory (SRAM) cell is disclosed thereafter. A storage element (SE) is comprised of four cross coupled FETs (Q1 to Q4). A fifth FET (Q5) is mounted in a transmission gate configuration between the bit line (BL) and a first common node (A) of the storage element. Its gate electrode is connected to the word line (WL). This FET is used to write the appropriate control data in the storage element for bit personality store. A sixth FET (Q6) is also mounted in a transmission gate configuration between the second common mode (B) of the storage element and an output line (OL). Its gate electrode is connected to the input (IL). Said second FET ensures that a logical function, e.g. AND/NAND is achieved between the signals available at said second common node and on said input line. Other configurations of said sixth FET (Q6) are allowed. These reprogrammable logic fuses may be disposed in matrixes to constitute reloadable logic arrays and Reloadable PLAs (RPLAs). In the latter case, in the AND array the input and output lines are respectively the product term lines (if bit partitioning is employed) and AND term lines (or Match Lines). In the OR array, the input and output lines are respectively the Match Out lines (the signal on the Match Line after complementation) and the OR out lines. RPLAs can be dynamically reprogrammed to allow in system logical reconfiguration in real time.
