Abstract: An operation method for a gaming machine sets a target payout rate, probabilities of winning, and odds on a plurality of objects. The objects are rearranged in order of the probability of winning. The odds on the object in first place are corrected to odds with a predetermined number of digits. The probability of winning of the object in the first place is corrected by the corrected odds. The difference between the uncorrected probability of winning and the corrected probability of winning is reflected in the probability of winning of the object in the subsequent place. The odds on the object in the subsequent place are predetermined based on the corrected probability of winning of the object in the subsequent place. The whole processing is repetitively performed for the objects in all places.

Abstract: The invention relates to an automatic machine tool, for the production of base structures, for false teeth, in particular, for tooth crowns and/or tooth bridges of exact three-dimensional shape. Said base structures may be fixed to prepared natural and/or artificial tooth stumps.

The machining paths for the blank are calculated from the measured and stored digitized data and a predetermined material-specific scaling factor, before the machining of the blank.

Abstract: A process for preparing a bimodal emulsion of viscous hydrocarbon in water includes providing a stream of water at ambient temperature; providing a liquid additive that tends to gel when mixed with water at temperatures less than a gelling temperature TG; heating the stream to provide a heated stream at a temperature TC which is greater than ambient temperature and less than the gelling temperature TG; feeding the heated stream to a mixer having a mixer inlet so as to impart energy to the heated stream; adding the liquid additive to the heated stream downstream of the mixer inlet, whereby the liquid additive mixes with the stream and the energy inhibits gelling of the liquid additive to provide a substantially homogeneous solution of additive in water. The solution is then divided and used to make two different droplet sized emulsions which are mixed to form the bimodal emulsion.
