  • Patent number: 6829985
    Abstract: Systems and methods for modifying, altering, constructing, or retrofitting an existing newspaper press having a first cut-off length, to have a second cut-off length which is different from and generally less than the first. These systems and methods generally provide for the machining of new bore holes into the existing press unit frame. The new bore holes will generally completely encompass the old bore holes and allow for linear translation of the axes of rotation of the new cylinders relative to the positions of the axes for the old cylinders.

  • Patent number: 6318649
    Abstract: A method for creating ultra-fine particles of material using a high-pressure mill is described. The method includes placing a material in a first chamber and subjecting the material to a high-pressure liquid jet to divide it into particles. These particles are then transferred to a second chamber in which they are subjected to cavitation to further divide the particles into relatively smaller particles. These relatively smaller particles are then transferred to a third chamber, in which the particles collide with a collider to still further divide them into ultra-fine particles of the material. The mill of the present invention includes a first chamber having an high-pressure liquid jet nozzle, first and second slurry nozzles, a second cavitation chamber and a third chamber which houses a collider. Sensors may be located throughout the mill to collect data on the comminution process and to use the data to control the resultant particle size.

  • Patent number: 5255519
    Abstract: A method and apparatus for converting heat energy to mechanical energy with greater efficiency. According to the method, heat energy is applied to a working fluid in a reservoir sufficient to convert the working fluid to a vapor and the working fluid is passed in vapor form to means such as a generator for converting the energy therein to mechanical work. The working fluid is then recycled to the reservoir. In order to increase the efficiency of this process, a gas having a molecular weight no greater than the approximate molecular weight of the working fluid is added to the working fluid in the reservoir and separated from the working fluid downstream from the reservoir.

  • Patent number: 5237816
    Abstract: Control systems (or controllers) for once through, unfired steam generators (or boilers) which control a single parameter--the feedwater flow to the boiler--in accord with an energy or enthalpy balance between the hot gases supplied to the boiler and the steam generated in it. These control systems have a predictive mode of feedwater control and, optionally, an operator selectable, feedback mode to compensate for drifts in the predictive mode. Other corrections may also be made, and predictive and corrective flow splits can be provided to obtain maximum efficiency when the control system is utilized to regulate the operation of a dual pressure boiler.

    Abstract: A composition that expands against an exerted pressure, which comprises a polymeric material having an inverse temperature transition in the range of liquid water, wherein at least a fraction of the monomers in the polymer contain a hydrophobic group that is present in an amount sufficient to provide PdV/dS for the polymer of at least K. The composition can be used in a variety of different application to produce mechanical work or cause chemical changes in a sealed environment by varying the pressure on the composition, with the degree of mechanical or chemical change being controlled by selection of the number, hydrophobicity, and size of the hydrophobic group and the presence or absence of reactive functional groups in the polymer.

  • Patent number: 5222362
    Abstract: A thermal actuator, also known as a heat capacitance motor, derives its energy from the physical expansion of paraffin wax as it changes from solid to liquid when heated within an enclosure such as a cylinder. This energy is converted into mechanical force which causes translation of a piston slidably mounted within the cylinder, thus creating hydrostatic pressure which is converted to work. The thermal actuator may be utilized in various drug delivery systems in which the hydrostatic pressure created by the actuator is used expel the contents of a syringe.

  • Patent number: 5220792
    Abstract: A method is provided for extracting heat from a hot liquid containing scaling material whose solubility is proportional to the temperature of the liquid. The method includes providing a pond containing a liquid, and locating in said pond a vertical tube having an upper end that is substantially closed, and an open lower end immersed in the liquid in the pond and spaced from the bottom thereof for establishing a trapped region above a column of liquid in the the tube. Hot liquid is supplied to the trapped region, and the pond and the tube are constructed and arranged so that the liquid in the pond and the liquid in the column are in substantial hydrostatic equilibrium. As a consequence, the trapped region is maintained at a pressure such that some of the liquid supplied to said trapped region flashes into a vapor thereby concentrating the liquid in the column.
