Abstract:
A gas cylinder includes a cylindrically-shaped main wall having a liner, a facing and insulation located between the liner and the facing. First and second electric, self-regulating heating elements are positioned between the liner and the insulation. The liner is provided with first and second pockets and the first and second heating elements are located within the pockets. The first heating element has a higher wattage density than the second heating element and the first heating element is located below the second heating element. A sealed conduit enclosure contains a terminal block connecting a power input cable to the first and second heating elements. A planar top wall is located at the top of the main wall and has an opening for passage of a regulator of the gas cylinder.

The present invention is directed to, among other things, a classifier assembly for mounting on the center shaft of a rotary coal pulverizer which includes a labyrinthian sealing arrangement operatively associated with the shaft for limiting the egress of unacceptably large coal particles from the pulverizer.
Abstract:
Methods and apparatuses generate a split power plane for a multiplayer printed circuit board (PCB). An aspect of the invention supports the generation of a split power plane by constructing wireframes corresponding to each of the power voltages. If a crossover between different voltage wireframes exists, at least one of the voltage wireframes may be modified in order to eliminate the crossover. With another aspect of the invention, a trace layout, corresponding to the wireframe, is constructed in accordance with electrical current requirements, e.g. average electrical current and peak electrical current, of the associated components. With another aspect of the invention, a plane that contain the traces that associated with a power voltage may be enhanced by increasing the associated area of the layout in accordance with the available area of the split power plane. The enhancement of a plane may be prioritized in accordance with peak electrical current that is associated with the plane.
Abstract:
A data storage subsystem that includes three data storage units, three check storage units, and an array controller coupled to the three data and three check storage units can tolerate failure of any three data and check storage units failures can be occur before data stored on the data storage subsystem is lost. Information is stored on the data storage subsystem as a symmetric Maximum Distance Separation code, such as a Winograd code, a Reed Solomon code, an EVENODD code or a derivative of an EVENODD code. The array controller determines the contents of the check storage units so that any three erasures of the data storage units and the check storage units can be corrected by the array controller. The array controller updates a block of data contained in any one of the data storage units and the check storage units using only six IO operations.
Abstract:
A process for manufacturing wire or needles having a taper point. Needle or wire blanks are cut from a roll of wire and mounted to a carrier strip. The carrier strip and needles are moved through a succession of forming and trimming and grinding stations. The blanks are preferably rotated in the strip while being ground.
Abstract:
A method of removing water from lubricants, coolants and the like consisting of the following described steps. Firstly, pass lubricants through a heater at a predetermined flow rate to decrease its viscosity. Secondly, pass the heated lubricants through a vertical separation vessel which agitates the lubricants such that water entrained in the lubricants is released as steam. Thirdly, recirculate the heated lubricants repeatedly through the separation vessel at a recirculation flow rate that exceeds by many times the flow rate through the heater, thereby improving the degree of separation of water from the lubricants with each pass through the separation vessel. Fourthly, draw lubricants periodically from the separation vessel as the flow rate through the heater permits.
Abstract:
An internal combustion rotary engine comprising a housing, at least one sun wheel centered about the central axis and positioned within one of at least one cylindrical compartment of the housing, and including a sun wheel circumference and at least one semicylindrical receptable defined along the sun wheel circumference, at least one lobe extending from an inner cylindrical surface of the compartment, and at least one planet wheel received in the at least one semicylindrical receptable of the sun wheel. The at least one planet wheel may be configured to engage the inner cylindrical surface of the cylindrical compartment and include at least one indentation configured to be received by the at least one lobe when the at least one planet wheel rotates along the inner cylindrical surface. Air intake and compression as well as combustion and exhaust may be performed within the same or different compartments of the at least one cylindrical compartment.
Abstract:
The purpose of diffusion assisted crystal hydrothermal growth is to facilitate a greatly increased crystal growth rate that would save time that is precious in such a material and manpower costly process. The assisted crystal growth itself requires the utilization of a piezoelectric shaker connected to the autoclave in which most industrial hydrothermal crystals are grown. The waveform can be modulated to induce transport of nutrient in a singular direction, customized to the topology of the apparatus. As it stands currently, the growth of most crystals that require autoclaves for their production can take anywhere from 3 months to up to 2 years, and accordingly carries many costs, particularly electricity and supervision of the autoclave(s), and other issues that may arise during the growth. While the product of this labor results in high-quality crystals, in reality, these are not at all what is needed outside of the laboratory environment. Using the assisted crystal hydrothermal growth process, average crystal growth can be cut in half, with the resulting crystals consequently being of a slightly lower quality, though still sufficient for most engineering purposes. Another advantage of using a piezoelectric shaker is that an additional sensor can be added to the autoclave to monitor the health of the autoclave using trending data obtained during the growth.
