Abstract: A method for producing electrical power the method, in certain aspects, including: producing a water/methanol mixture; feeding the water/methanol mixture to converting apparatus for converting said mixture to a feed stream, the feed stream including hydrogen, carbon dioxide, and steam; combusting the feed stream to produce a stream for powering a turbine; feeding the stream to the turbine to power the turbine; driving an electrical generator with the turbine to produce electricity; recovering steam from the converting apparatus and feeding it back into the reformer; and, optionally, vaporizing steam recovered from the reformer and then introducing products of such vaporization back into the reformer.

Abstract: A method for producing electrical power, the method, in certain aspects, including producing a water/methanol mixture, feeding the water/methanol mixture to apparatus for converting said mixture to a feed stream, the feed stream including hydrogen, carbon dioxide, and steam, combusting the feed stream to produce a stream for powering a turbine, feeding the stream to the turbine to power the turbine, and driving an electrical generator with the turbine to produce electricity.

Abstract: An electrical power generating system has been invented, with, in one aspect, a combustion chamber for the combustion of oxygen and hydrogen and for producing hot water and hot gas, a first turbine system fired by the hot gas from the combustion chamber producing electrical power and hot water, a tank for the collection of hot water from the combustion chamber and from the first turbine system, a steam boiler receiving hot water from the tank and producing steam, a second turbine system run by the steam from the steam boiler and producing electrical power and hot water. A method for producing electrical power has been invented using such an electrical power generating system.

Abstract: A gate valve bonnet closure which can be quickly and safely serviced with common tools. The valve bonnet fits within the valve body. Lock elements in contact with the bonnet fit into an annular groove in the body. The lock elements are of a size and configuration so as to allow location within the groove for substantially the full extent of the annular groove or, spaces between adjacent lock elements can be filled by retaining plates preferably bolted to the bonnet to prevent movement of the lock elements. Pressure sensing vents or bolts are preferably used to prevent opening of the valve when there is pressure in the valve body. The pressure sensing bolts holding retaining plates in place include a hollow bore which is sealed when the bolt is fully seated but is exposed when the bolt is rotated a small number of times to indicate and bleed off pressure within the valve.

Abstract: A new and improved anti-two block system adapted to be used with a crane for the prevention of damage to the boom tip of the boom of the crane by the travelling member wherein the two block system of the present invention includes an engaging mechanism movably mounted with the boom tip for engaging the travelling member when the travelling member moves into close proximity to the boom tip during lifting operations of the travelling member with the crane for the prevention of damage thereto.

Abstract: The method for removing a bearing assembly disposed between a revolving turntable of a pedestal crane assembly and the pedestal and a removable bearing assembly for a pedestal crane, wherein the method includes activating a support member coacting between the revolving turntable and the upper end of the pedestal for raising and supporting the pedestal crane assembly from the support column of the pedestal, centering the revolving turntable about the support column of the pedestal with alignment structure, removing a retainer plate that secures thrust and radial bearings in position with respect to the revolving turntable and the upper end of the pedestal to permit access and removal of the bearings.

Abstract: An anti-two block system adapted to be used with a crane having a sensor device mounted with the boom point of the crane in communication with a hoisting actuator mechanism such that the sensor device effects movement of the hoisting lever of the crane to discontinue the lifting force exerted on the lifting line when the travelling member engages the sensor device.

Abstract: In a crane having a boom adapted to be mounted on a pedestal, a crane mounting system having a crosshead assembly and a bearing means, the crosshead assembly for connection to the crane boom and adapted to be rotatively mounted in proximity to the upper end of the pedestal and the bearing means allowing rotation and limited pivotal movement of the crosshead assembly with respect to the pedestal.

Abstract: In a crane having a boom, a load cable, a traveling block and multiple sheaves for the cable, an improved sheaving arrangement for preventing spinning of the traveling block and twisting of the cable when raising and lowering the traveling block.
