Also described is the method for heat treating such an alloy to achieve the desired surface hardness, on the order of Rockwell C58 and higher. The alloy contains, as essential constituents, 0.1 to 0.3% carbon, 0.2 to 1% manganese, 0.2 to 0.6% silicon, from an effective amount up to 1.2% chromium, 2.5 to 3.5% nickel, 4 to 6% molybdenum and 0.25 to .85% vanadium.

Abstract: A process for carrying out an endothermic chemical reaction, such as the water-gas reaction, wherein heat is supplied to the reaction from nuclear reactor cooling gases. The invention is characterized in that water vapor and fuel, for example, are passed through a series of heat exchangers and reaction chambers in series, the heat exchangers being disposed within a conduit through which cooling gases from a nuclear reactor flow. When a fuel such as methane, for example, is being dissociated in the endothermic reaction, additional fuel is added to each reaction chamber where heat is supplied from the nuclear reactor cooling medium via a separate heat exchanger for that chamber.

Abstract: A flue gas collector for coke ovens, particularly regeneratively-heated coke ovens, wherein the base, crown and side walls of the flue gas collector are formed from reinforced concrete in a generally rectangular cross-sectional configuration and are provided with insulating material on their interior surfaces. Additionally, insulating material is disposed between apertures in the flue gas collector and the ends of outlet pipes leading from changeover valves connected to the coke oven regenerators. The insulation is of such nature and thickness so as to insure that the reinforced concrete body of the collector assumes only negligible temperatures throughout, thereby eliminating cracks and leaks in the walls of the collector.

Abstract: A coke guide machine includes a shuttle car carried by rails on a coke bench for a battery of coke ovens. Movable along the shuttle car is a carriage having two support stations that are rotatable about a common vertical axis. The support stations include scissor arms that form extendible support devices, one of which carries a handling device for a coke oven door and the other carries a device adapted to clean exposed sealing surfaces of an emptied coking chamber. The carriage also supports a coke guide including an extendible section to bridge an open passageway wherein an inspection car moves along the coke bench between the shuttle car and the coke ovens. A door cleaning machine is positioned in a stationary manner on the shuttle car to clean a coke oven door carried to it by the door handling device after 180.degree.

Abstract: The control system includes a controller and a clocking circuit along with a computer for each one of the coke oven chambers. A first control signal is responsive to the occurrence of charging coal into a given oven chamber and starts the clock. A second control signal is responsive to the pushing of coke from the oven chamber and stops the clock. When the duration of the coking time for a given oven chamber exceeds a predetermined coking time, the controller provides a signal for operating valves to terminate the flow of combustion gases into heating flues at the sides of that coke oven chamber. In the system, the computer updates coking time and establishes from time-to-time from data fed to it, the thermal state of each heating flue in the battery.

Abstract: A plurality of base members are seated on an ocean bed adjacent the shore and they support at their shore ends normally expanded compression cylinders provided with fluid inlets and outlets controlled by check valves. The outlets are connected by conduits with the inlet of a turbine that is operatively connected with an electric generator. Rigid pressure plates are disposed above the base members and the cylinders thereon and are inclined downwardly from their shore ends to their opposite ends, where they are hinged to the off-shore ends of the base members. Waves passing over the pressure plates will force their upper ends down to compress the cylinders to force fluid through the conduits to the turbine, after which spring means will expand the cylinders and raise the pressure plates. The base members are located in such positions on the ocean bed that the pressure plates will be depressed in succession to provide substantially constant flow of fluid to the turbine.

Abstract: A charging car supports a plurality of hoppers in a manner such that two hoppers for supplying coal to adjacent charging holes are supported one after the other in a consecutive relationship along a line which is generally parallel to movement by the charging car. A conveyor conducts coal from each hopper to a telescopic charging tube which communicates with the charging hole in the roof of a coking chamber. Skirt-like walls enclose the sides of the spaces containing two of the hoppers to conduct smoke and other gases upwardly toward a roof which is supported by stanchions at each side of the battery of coke ovens. In one embodiment, two roof sections extend from the sides of a battery of coke ovens toward the center thereof. Gas-conducting mains receive gases via outlet pipes having control valves from the spaces beneath the roofs.

Abstract: A process to remove ammonia from gases by washing the gases with an inorganic acid of ammonium bisulfite. The ammonia removed from the gas transforms the washing liquid into ammonium salt solution. This salt solution then undergoes a separate processing by washing it with gases bearing sulfur dioxide to regenerate ammonium bisulfite acid, a portion of which is returned for further washing of the gases and another portion is diverted to an apparatus for concentrating the acid solution up to 70% to 80% by weight after which the concentrated acid solution is delivered to a combustion chamber where burning thereof produces combustion products bearing sulfur dioxide which are used in the process to wash the ammonium bisulfite salt solution to regenerate ammonium bisulfite acid.

Abstract: A lubricant for glass molds and forging dies and for mandrels used in seamless tube manufacture is formed from a mixture consisting principally of gilsonite powder and water, but containing a dispersant and a thickener. When the lubricant is intended for mandrels, sufficient thickener is used to give it a paste-like consistency similar to a light grease.

Abstract: Apparatus to maintain the desired water level in a swimming pool includes a stilling chamber receiving pool water from an equalizer pipe connected to the pool essentially below the desired water level. The stilling chamber is located externally of the swimming pool at the same general elevation as the desired water level so that a water level detector in the stilling chamber will open a valve in a water supply line to supply make-up quantities of water to the swimming pool to maintain the desired water level therein. In one form, the detector includes a plurality of probes extending downwardly within a secondary stilling chamber member located within the main stilling chamber. A relay unit receives an electrical signal when the detected water level falls below a desired water level to open a solenoid-operated valve located in the water supply pipe. In the second embodment, a valve assembly in the stilling chamber is mechanically operated by a float connected by a control arm to the valve assembly.

Abstract: A first roll is provided in its periphery with a row of vacuum holes extending lengthwise thereof for holding against it the previously folded leading edge of a traveling envelope having an unfolded closing flap at the trailing edge of the side of the envelope remote from the roll. The roll carries the envelope between it and a second roll rotating in the opposite direction and also provided with a row of vacuum holes to hold the closing flap against it so that the envelope will be pulled away from the first roll and the flap will be folded behind the adjoining portion of the envelope. After the envelope has been pressed against the second roll to crease the fold at the flap, the envelope is removed from the second roll.

Abstract: An elastomeric bearing is provided for oscillatory motion which is also capable of operation as a slider bearing under high radial loads and for large motions. The bearing consists of concentric bearing members with opposed recesses forming a cavity for a mass of elastomeric material bonded to the bearing members. The bearing members have opposed bearing surfaces normally spaced apart a predetermined distance, and restraining members are provided on each side of the elastomeric material to limit its axial deflection. Under heavy radial loads, the space between the bearing surfaces closes to limit the radial deflection of the elastomer. A lubricant is preferably provided between the bearing surfaces to enable them to function as a slider bearing through a relatively large angle.

Abstract: Regenerative heating of a coke oven battery includes the combustion of lean gas and air in heating chambers disposed between the coking chambers or, alternatively, if desired, the combustion of rich gas and air in the heating chambers. Each heating chamber includes a plurality of header walls forming upgoing and downgoing heating flues. Each header wall includes at least one internal duct in open communication with a plurality of vertically-spaced exit ports at the common side of a header wall. The internal ducts receive either preheated air or preheated lean gas for combustion in a heating flue. The cross-sectional size of the exit ports to discharge air in a given heating flue increases upwardly from port to port along the header wall whereby the amount of air supplied at the sole and lower part of the heating flue is insufficient for complete combustion of the amount of lean gas supplied thereto.

Abstract: Fine-grain fuel is carbonized at a low temperature by feeding the fuel from a hopper downwardly into the gap formed between two vertically-arranged, plate-type conveyors. The plates of each conveyor move downwardly while their back face surfaces bear against the wall of a heating chamber. The position of the heating chambers is controlled to maintain a narrow gap, e.g., 10-30 millimeters between the plates of the conveyors. The conveyors and heating chambers are located within a container wherein a pressure of up to 100 bars is maintained and a clear gas is passed countercurrently to the downward advancement of the fuel in the gap between the conveyors. Breaker rollers below the conveyors subdivide the carbonized fuel issuing from the gap for passage into a gasification chamber. Part of the gas yield is used as fuel for the heating chambers.

Abstract: An anti-theft and mounting assembly is employed to attach a CB radio receiver and transmitter onto the instrument cowl of a vehicle. The radio casing is secured to the side members of a U-shaped frame that also includes a bottom plate used to support an outwardly projecting lug carrying a key-operated lock. A rectangularly-shaped housing receives and supports the U-shaped frame together with the casing of the CB radio. A lock box on the bottom wall of the housing is totally enclosed by the lug and a stop plate in the box cooperates with the lock mechanism to interconnect the U-shaped frame and the housing while at the same time the lock permits authorized removal of the CB radio should the vehicle remain unattended for long periods of time.

Abstract: A level-sensing collar is rigidly mounted on a vertical tubular nozzle of a container-filling machine. The collar is located a predetermined distance above the nozzle outlet and is provided in its bottom with an upwardly extending recess encircling the nozzle. The collar also has a plurality of circumferentially spaced openings connecting its recess with the lower ends of air tubes that extend up along the nozzle to air-receiving means that first receives high pressure air to blow down out of the collar recess any product that has accumulated in it and then receives low pressure air for delivery to the collar recess so that when the level of the product in a surrounding container rises high enough to close the recess the air pressure in the tubes will built up and shut off the delivery of the product to the container.
