Abstract: A combination gas and oil burner is disclosed for heating a radiant wall in a reforming furnace for petroleum refinery processes or the like to provide heat for radiation by the wall and in which oil, gas, or both fuels, may be employed, the burners being readily removable for inspection and maintenance, and in which operation can be effected with one fuel with the apparatus for the other fuel being removed without shutting down the operation, and with greater stability attained by surrounding the flame passageways with refractory faces.

Abstract: A wave operated power plant is provided wherein a buoyant vessel is anchored on the ocean surface with the wave motion causing displacement of water carried in a chamber in the hull such that upon rocking motion the water is forced upwardly through pipes on one side of the vessel. The water contacts turbine blades which through shafts rotate electrical generators and generate electricity. The water is returned to the chamber when the vessel moves in the opposite direction and the cycle is repeated with water forced up through pipes in the other side of the vessel, used for electrical generation and then returned to the chamber. The water being forced up from the chamber can contact the blades directly or be stored in a tank on top of the vessel and released at a predetermined rate.

Abstract: A candle mold is described having a barrel open at each end, with a plate in sealing contact with one end removably held thereto by a flexible end cap which fits over the barrel and plate forming a mold into which wax can be formed. The end cap has a centrally located hole for engagement of a wick which passes therethrough and through a centrally located hole in the plate to the end of the barrel where it may be retained by a wick holder.

Abstract: Tubular articles and the like and methods of making the same are disclosed, the tubular article being of desired tortuous shape, strong and rigid, free from porosity, light in weight, resistant to high and low temperatures with outerskin layers to improve fluid conveying and storage characteristics for example an exterior metallic foil or mesh lamina or skin of heat reflective and dispersive qualities and suitable for electric resistance heating if desired. The article is formed in a mold with an inflatable mandrel which carries a surrounding knitted fabric resin carrying component and with an exterior lamina or skin which is applied in the mold for subsequent integration in the article by matrix curing.

Abstract: A crude oil burner is provided particularly suited for oil well testing in Arctic and sub-Arctic regions having a plurality of aligned and spaced air cones to the rear end of which crude oil is delivered, and into which air is induced. Air is also available at the space between the cones and at the front of the front cone. Gas assist heads are provided connected to a ring at the space between the cones and connected to a ring at the front of the front cone for inducing air and aiding in the combustion of the crude oil to provide smokeless combustion. The burner can be mounted for turning in accordance with the wind direction to avoid undesired deflection of the flame by the wind.

Abstract: A flare gas burner is described for the smokeless combustion of flare gas at low noise level with the flare gas mixed with steam at the end of the flare burner, the steam being introduced into the flare gas flow and at the center of the vortex of the flow. The apparatus includes vanes to mix the gases and steam and acoustically lined baffling to reduce noise.

Abstract: A transport roller is disclosed for advancing elongated strips of flat sheet material such as photographic film, paper and the like in tanks for chemical treatment, in driers and for other purposes which comprises a hollow tubular roller body having shafts extending from its ends, with an improved leakproof and quickly assembled shaft mounting being provided in expanded frictional engagement with the tube.

Abstract: A flare gas burner is described for the smokeless combustion of flare gas at low noise level with the flare gas delivered in a hollow whirling path for burning, ignited and burned with air and steam delivered interiorly and exteriorly, also in whirling paths intersecting or overlapping the delivered flare gas, additional steam being supplied at the outer margin of the outer air path, a diffuser being provided for the interior air and steam. The structure is also provided with a diode in the gas path to prevent flashback and with accoustically lined baffling to reduce noise.

Abstract: Apparatus is described for injecting grout or cementitious material into a small diameter hole which has been bored in the soil at a depth below a larger diameter hole for the purpose of obtaining an intact sample of soil and/or rock formation. The smaller diameter or second hole has a hollow rod from the apparatus inserted into it and grout injected through it and therearound into contact with the soil. The rod is detached from the apparatus which is removed and the mass of soil, rod and grout is recovered by overboring in a conventional manner.

Abstract: Heavy duty stake rack connectors for joining of racks for flat bed trucks and trailers which racks have upright portions engaged in hollow sockets of the truck or trailer bed are provided. The connectors may be formed as extrusions and operate as pairs of male and female connectors one at each end of the rack. The female connectors have U-shaped portions for the reception of vertical ribs from male connectors. Both connectors are symmetrical which avoids the necessity for right and left hand connectors. If desired, a portion of the male connector may be removed to provide a hinge pin on one side and a like portion of female connector at the opposite end of the racks removed permitting the rack to be swung away from an adjacent rack after vertical displacement and disengagement of its uprights from their sockets. The racks can be of picket or solid wall construction.

Abstract: Liquid level responsive apparatus is provided which includes a tube having a lower terminal end immersed in the liquid in a container uncovered when the liquid level is below the terminal end for discharge of air from the tube, the tube having a small electric motor driven air pump supplying air thereto, the tube having a pressure tap connected to one side of a diaphragm for normally maintaining the diaphragm in one control position, the diaphragm being collapsible to another control position, the tube having a vent of predetermined size for limited venting of air from the tube while the diaphragm is maintained in its one control position. The diaphragm can control a microswitch which in turn can control any desired operation such as shut-off of delivery. A plurality of tubes can be connected in parallel with their terminal ends in different liquid containers.
