Abstract: Storage stable fluorocarbon emulsions having a continuous aqueous phase and a discontinuous fluorocarbon phase, in which the fluorocarbon phase comprises a major amount of a first fluorocarbon or fluorocarbon mixture, and a minor amount of a second fluorocarbon or fluorocarbon mixture, in which the second fluorocarbon has a molecular weight greater than that of the first fluorocarbon and the second fluorocarbon includes a lipophilic moiety in its structure, whereby the second fluorocarbon serves to promote particle size stability in the emulsion while simultaneously providing favorably short organ retention times when administered to animals in vivo.

Abstract: The random number generating capability of a computer is used as a basis for producing sets of alphanumeric configurations for a plurality of bingo cards, and the comparator capability of the computer is utilized to eliminate duplication from among the plurality. A computer-controlled, high-speed graphics printer is used to print, on sheets of paper, bingo cards from among the plurality.

Abstract: A computer uses a random number generator as the basis for formatting the number combinations of new bingo cards, and stores each new combination in memory. This proceeds until the number of generated and stored cards reaches a designated number, whereupon the computer scans the combinations in memory to detect duplicates, and removes combinations in such a way as to eliminate duplication. A high-spoeed, graphics printer, for example a laser printer, is then used and computer-controlled to print bingo cards on paper, using the number combinations in memory.

Abstract: A method for prevention of unauthorized copying from information recording media, such as diskettes, comprising the steps of altering the information storage characteristics of the information recording media at selectable locations thereon, analyzing the information recording media after the alteration to provide a storable indication of the precise locations of the alteration, and recording onto the altered recording media information the copying of which is to be resisted, the information thus recorded including said storable indication of the precise locations of the alteration and instructions to user apparatus to verify the altered status of the recording media at said precise locations. A protected recording medium is also disclosed and claimed.

Abstract: An armature winding distribution for an electric motor divides each armature coil into first and second coil sub-sections inter-distributed with one another so that the first and second coil sub-sections of an armature coil undergoing commutation at one of the brushes are coupled, respectively, to the coil sub-section of an armature coil about to undergo commutation by the other brush and the coil sub-section of another armature coil having just completed commutation by the other brush. Excess energy in the armature coil undergoing commutation by the first-mentioned brush is transferred to a coil sub-section of the coil just about to undergo commutation and/or a coil sub-section of the coil having just completed commutation by the other of the brushes. The armature winding distribution improves commutation and substantially reduces brush sparking and the generation of electromagnetic interference (EMI) across a wide range of frequencies.

Abstract: A small motor, for either universal or D. C. applications and useful in the fractional horsepower range, is described. The motor includes a wound armature, commutator and brushes, and a two pole wound field. The motor may be of the series, shunt or compound type. An improved field structure which utilizes an improved cross sectional shape is disclosed.
