Abstract: In a reactor suitable for gas-phase catalytic exothermic synthesis, in particular of ammonia or methanol the synthesis gas is reacted in an upstream adiabatic catalytic zone, is cooled in a heat exchanger and then reacted further in a downstream catalytic zone, whereafter preferably it is cooled again, suitably in a boiler or feed water heater, and reacted further in a further catalytic zone. The gas flow through the catalyst is mainly in an axial direction and the pressure drop is kept low by disposing the catalyst in each zone in a plurality of beds fed in parallel from an inlet header and delivered in parallel into an outlet header. The beds may be separately removable from the reactor to facilitate catalyst charging and discharging.

Abstract: A used lubricating oil reclamation apparatus in which filters, heat exchangers, a vaporizer unit, pumps and other necessary equipment are all contained in a wheeled cabinet. The oil to be reclaimed is pumped through a warming heat exchanger, a first filter, a vaporizer unit, and further filters, after which appropriate additives are mixed into the decontaminated oil in a mixing tank. A vacuum is maintained on the vaporizer unit to exhaust the vapours from it via the heat exchanger and a condensate tank.

Abstract: Apparatus for use with extremely low-grade aggregate ore, for deriving a concentrate comprised of metal-bearing ore particles having densities within a predetermined range. The apparatus is in the form of a mobile, self-sustained system including a vehicle trailer for horizontal transport and elevated operational support, plus an integral power system capable of supplying the total energy requirements of the apparatus. Two types of particle size separation are applied, followed by compaction and particle density separation. Two density separation areas are provided to effect both coarse and fine gravitational shaving actions, and dual adjustment controls are also provided to vary the shaving force intensity to derive the concentrate independently of changes in the particular characteristics of the aggregate being processed. The apparatus includes outer and inner cylindrical chambers concentrically mounted on the trailer so as to be tiltable and rotatable.

Abstract: A process for calcining green coke containing water and combustible volatile matter and obtained by a delayed coking process in three or more stages of heating furnaces which are connected in series, and the control of the temperature and the adjustment of the atmosphere in the respective furnaces can be independently carried out, which process comprises carrying out, in respective furnaces in the indicated order, the steps of:(a) evaporating the water contained in the green coke, and drying and pre-heating the coke;(b) distilling off and burning the volatile matter from the dried coke; and(c) heating and calcining the coke from the step (b).Because each furnace can be controlled independently from the other furnaces in the above described process, it is possible to produce high-grade coke without process difficulties such as the loss of the coke by combustion and the formation of coke ring.

Abstract: Method and machine and a log product for log house construction includes improvements in apparatus to shape, and finish the logs, divide into halves or quarter sections for tongue-and-groove assembly construction of floors, walls, or ceilings appurtenant to the log house. Equally-spaced holes between the tongues and grooves provide additional functional uses for utility lines or vertical supports as needed. The logs are finished by spraying them with selected fluids such as preservatives.

Abstract: Acylated hydroxyalkylaminoalkylamides, the N-alkylated derivatives thereof, and the preparation thereof and uses thereof as corrosion inhibitors.

Abstract: An elbow cover for a coke oven ascension pipe characterized in that the opening which is covered is oval in shape and is formed at the junction of the ascension pipe and a downwardly-extending supply pipe leading to a gas-collecting main. The oval-shaped cover is provided with an immersion cup seal and a spaced sealing plate. Because of the oval shape of the opening, cleaning tools can be readily inserted into the opening to clean both the ascension pipe as well as the supply pipe.

Abstract: An ozone generating apparatus which comprises a plurality of chambers filled with an adsorbent, wherein a wet raw air is fed through one of the chambers filled with the adsorbent to adsorb moisture to form a dry air and the dry air is fed into an ozonizer to convert it into a dry ozone-containing air, and all or part of the dry ozone-containing air is fed into the other chamber filled with the adsorbent to purge water adsorbed on the adsorbent and to discharge it as a wet ozone containing air. The valves are then switched to feed the wet air to the other chamber filled with the adsorbent, whereby the moisture is adsorbed and the dry ozone-containing air fed from the ozonizer is fed into the former chamber filled with the adsorbent to reactivate the adsorbent and to discharge it as the wet ozone-containing air. The cycle is continuously repeated by switching valves.

Abstract: A pinned shaft and correspondingly a pinned shell are described having the pins attached to the cylindrical surfaces in such a manner that all of the pins are arranged in a geometrically symmetrical pattern of squares or equilateral triangles or equilateral hexagons with the further provision that the pins are not arranged along straight lines or on circles. By this arrangement of pins a very uniform action of the pins is achieved, the pin density being constant over the entire pinned shaft and the distance between adjacent pins being identical all over the pinned shell. A carbon black pelleting device incorporating such a pinned shaft.

Abstract: A method and apparatus for sterilizing highly infectious material. The sterilizer incorporates an inner chamber having no drain line and having a reservoir created by low dams at the bottom of the inner chamber at each end for collecting condensate during the sterilizing cycle. The chamber has a steam jacket. Water for sterilizing can be introduced into the chamber at the time the chamber is loaded.

Abstract: Apparatus for cleaning a coke oven door, which has upper and lower closing surfaces and two side closing surfaces which are to be cleaned, the cleaning apparatus being relatively positionable in a position for cleaning when the door is open, comprising a mobile frame having positioning surfaces engageable with guide surfaces at the said upper, lower and two side surfaces of the door in order to locate the door and apparatus in the cleaning position, the frame including horizontally extending upper and lower guide elements and at least one vertically extending guide element, carriages movable along the guide elements, fluid jets carried by said carriages directed (in the cleaning position) at the closing surfaces, at least one jet on the carriage which moves along the vertically extending guide element being connected by at least one resilient element to that carriage and there being at least one follower member connected to the jet which in use engages and is pressed by the resilient element against a guide s

Abstract: Apparatus for producing a product such as fertilizer which has acidic and basic constituents having, a venturi pump and a mixing tank. The venturi pump is powered by mixing the constituents in a reaction chamber and expelling the resulting product through a venturi tube. The venturi tube entrains additional product adjacent to the entrance of the tube and expels the additional product along with the product just produced by the reaction in order to mix the product in the tank.

Abstract: A method and apparatus for spotting a pusher machine or other door-handling machine in relation to a coke oven. The method and apparatus are particularly useful for aligning a door extractor carrying a door with an open hot oven, but also may be used to align a pusher ram. The apparatus includes left and right heat or light sensitive detectors at opposite sides of the part to be aligned with the oven and aimed at oblique angles toward the extended center line of the part. When both detectors are actuated simultaneously, the part is aligned accurately with the oven.
