  • Patent number: 7749058
    Abstract: This invention is a networked board game apparatus and method of playing a customized game for 2 or more players on recursively organized boards, and a method for applying the aforementioned to leadership, communications, and team building education, and further to apply the aforementioned to the specific form of Chess. Applied to form of Chess, the first board is identical to a chessboard. The second board is an 8× multiple of the first board. Tartary boards follow this exponential growth. Players alternate moving pieces to a game-ending condition. Two players lead, the next 32 players play on a second board. Each first board move changes the positions of a second board player's pieces by a uniform transformation where the first board piece's new position is a function moving the second board player's pieces, which then continue from their new positions, potentially affecting deeper levels.

  • Publication number: 20100129474
    Abstract: A method for the control of microorganisms, fungi or oomycetes in agriculture, said method comprising applying to plants or to the environment thereof, an anti-microbial, anti-fungal or anti-oomycetes effective amount of a combination of: (i) an agriculturally acceptable acidifying agent, and (ii) an agriculturally acceptable source of nitrite ions or a nitrate precursor thereof, wherein the combination of (i) and (ii) acts as a source of nitric oxide. Systems and compositions for use in this method are also described and claimed.

  • Patent number: 5469952
    Abstract: Coin discrimination apparatus includes a coin rundown path along which coins roll so as to impact a snubber provided with a piezo electric device. The coin impact produces an oscillatory voltage output from the device, which is sampled over a predetermined period for its peak maximum and minimum values. The values are combined in a predetermined relationship to produce a coin parameter signal indicative of coin mass and the material from which it is made. Coin acceptability is determined on the basis of the value of the coin parameter signal.

  • Patent number: 5180046
    Abstract: Coin discrimination apparatus comprises a path (1) for passage of coins under test; sensor coils (2, 3, 4) forming an inductive coupling with a coin under test during its passage along the path, each of the sensor coils being connected in a resonant circuit (10, 11, 12) which exhibits a resonant frequency that varies in dependence upon the inductive coupling between the coil and coin, control circuitry (14) which maintains the resonant circuit at the resonant frequency while a coin under test is inductively coupled to the coil, and amplitude responsive circuitry (MPU) responsive to the change in the amplitude of an oscillatory signal developed by the resonant circuit when the coin under test passes the sensor coil to discriminate between different coins, wherein the control circuitry includes a zero crossing detector (A1) responsive to the oscillatory signal crossing a zero threshold level for producing a rectangular waveform corresponding to the oscillatory signal, and drive circuitry (FF1, 2; OR1, 2) respon

  • Patent number: 4042629
    Abstract: Process for the manufacture of hexamethylene diamine comprising the steps of contacting 2-cyanocyclopentanone alone or in mixture with adiponitrile with a mixture comprising ammonia and hydrogen in the presence of a catalyst prepared by reducing iron oxide with hydrogen. The process is conveniently conducted at a temperature in the range 100.degree. to 275.degree. C and at a pressure in the range of 300 to 600 kg/cm.sup.2. The mole ratio of ammonia to 2-cyanocyclopentanone is maintained at least 4:1 and the pressure of hydrogen is sufficient to essentially prevent conversion of the activated catalyst to iron oxide.
