Abstract: A rubberless neoprene boot waterproofed from the inside comprised of a composite sock fabricated from a neoprene foam, coated with a polyurethane film sandwiched by an inner boot liner and a stretchable external layer that may be stretched and formed upon a shoe last. A composite upper shaft section made of neoprene foam, polyurethane film and an inner boot liner, and a semi-stretchable external durable fabric extending from said sock. An external foot jacket jacketing the sock forming an upper boot unit having internal seams with a series of thermoplastic heat sealing tapes to collectively seal all said internal seams against the penetration of moisture and a toe reinforcing stiffener and a heel reinforcing stiffener located between the stretchable external layer of said sock and the foot jacket. An inner sole secured to the sock and an outer sole securely anchored to a bottom end of the inner sole.

Abstract: An insulated building block having a three-section configuration wherein a first cementitious segment containing the internal core hole of the block is interlocked with second cementitious segment by a serpentine configured insulated insert. The insulation insert is operatively arranged to have multiple lips that mate with various indented ledges on each of the other segments in a location proximate to the surface of the cementitious segments. The insulating insert is also configured with wedge holes that accommodate wedges which press into the installation to maintain continuity of the block. The insulation insert has groves that in combination with the other segments form a trough in fluid communication with weep holes which extend through the insulation insert which allows for condensation and seepage of water to drain from the block.

Abstract: A method of treating sewage sludge that has a solids concentration of about 18-35% by weight includes treating the sewage sludge with sodium hydroxide, potassium hydroxide, or a combination thereof to increase its pH to at least about 12, and treating the sewage sludge with calcium oxide. The treatment of the sewage sludge with the calcium oxide can take place before and/or during the treatment of the sludge with the sodium hydroxide, potassium hydroxide, or a combination thereof. The amount of calcium oxide used is about 0.05-0.8% by weight of the sewage sludge.

Abstract: A suspension system for a motor vehicle that controls torque reaction comprising a chassis, a rigid drive axle, an opposite axle, a road wheel attached to each end of each axle, at least one torque reaction control link positioned longitudinally of the motor vehicle between the road wheels, at least two longitudinal control arms attached proximate the road wheels, for longitudinal control of the drive axle, so that the at least one torque reaction control link has a longitudinal plane that extends longitudinally of the motor vehicle and whereby the effective projection lines of the at least two longitudinal control arms and the longitudinal plane of the at least one torque reaction control link intersect each other in the direction of the opposite axle, forming a convergent angle and that when a force moves the rigid drive axle vertically up the convergent angle does not increase.

Abstract: The present invention relates to a method and apparatus for effectively reducing/eliminating oscillation of over and under shoot of superheat and refrigerant feed in an evaporator of compressed refrigerant of a gas/air dryer system. The feed makes use of a plurality of refrigerant expansion valves, sized in scaled manner, and adjusted inversely to the size of each, affording exact feed requirements to the evaporating vessel heat exchange. The system uses superheat feedback to respond rapidly or slowly to fill need for large or modest injections leading to stable, balanced operations. The operations ‘level-out’ to a smooth, even output of the gas/air dryer dew point temperature, relatively close to the dew point seat point without falling into an endless loop oscillation. The feed delivery of staged injection meters expanded refrigerant to demand while tracking superheat.

Abstract: A steam generator system comprising a coal-fired steam generator in fluid communication with a regenerative air preheater. The steam generator being adapted to receive a flow of heated combustion air exiting from the regenerative air preheater and to discharge a flow of hot flue gas to the regenerative air preheater. The regenerative air preheater adapted to receive a flow of cool air in counter flow to the flow of hot flue gas and to provide a heat exchange between the cool air and the hot flue gas to convert the cool air into the heated combustion air exiting to the steam generator. The steam generator system further comprising a first flow of heated air, diverted from the flow of heated combustion air, and routed through a source of pulverized coal to form a mixture comprising heated air and pulverized coal. The mixture being directed, by means of a fan positioned downstream of the source of pulverized coal, to the steam generator for combustion therein.

Abstract: The present invention relates to a method and apparatus for effectively reducing/eliminating shut-downs while still allowing an air or gas dryer apparatus to operate even though the conditions, even extreme conditions, may be out of range. The present invention comprises a system and apparatus controlling a variable speed compressor system for an air or gas dryer, the system and apparatus comprising a set point value that causes system shut down when reached and an algorithm that operates using the set point value. A sensor that provides an input value to the algorithm whereupon the algorithm compares the input value to the set point value, a circuit carrying output of the algorithm, a controlled device responding to the output and a feedback circuit that operates to maintain a product value at a set point or within a set range where the algorithm operating to modulate or bypass the feedback circuit when the input value approaches the set point.

Abstract: A lottery card holder and marking guide comprising a rectangular opaque base sheet and a transparent outer sheet aligned therewith, and joined with the base sheet along at least one edge thereof, the transparent outer sheet and base sheet being configured to hold a lottery card therebetween; the lottery card having imprinted thereon a multiplicity of wager sections, each wager section having imprinted therein a multiplicity of boxes arranged in rows and columns; the transparent outer sheet having a multiplicity of open slots arranged in rows and columns configured in the same pattern as the multiplicity of boxes in the wager sections so that when the lottery card is positioned in the holder and marking guide, each of said slots will be aligned with a corresponding box on the lottery card.

Abstract: A system for modulating refrigerant flow from an evaporator of an air or gas drying apparatus wherein the air or gas drying apparatus has an evaporator shell with at least one exit orifice for return of refrigerant to an accumulator or compressor. The system comprising a flow metering structure connected to the at least one exit orifice, the structure having an internal tube with a vertical rise from an evaporator shell end to an accumulator or compressor end, the internal tube having at least one return orifice (a) which allows passage of liquid refrigerant outside the internal tube into the internal tube, and at least one return orifice (b) which allows passage of gas outside the internal tube into the internal tube.
