Title: Processes and apparatus for the conversion of hydrocarbon oils
IPC: C10G9/00
Filed: 1920-11-08
Abstract: 163,277. Emerson, V. L. May 6, 1920, [Convention date]. Hydrocarbons, cracking. - In converting heavy into lighter hydrocarbon oils, vapours from a still 1 of the kind described in Specification 143,217 are passed by a pipe 2 into a chamber 18 of a second still 4 in which they are submitted to violent impacts, either by passage through two or more opposed jets 27 or by injection through a jet against a baffle. The vapours pass into the oil in the still 4 through a perforated bell mouth 20, and serve to heat the oil and drive off water vapour and sulphur compounds. Heavy constituents are condensed from the vapours, and the lighter vapours pass by a dome 32 and pipe 33 to a condenser. An annular baffle 22 assists in circulating the oil. Oil may be drawn through pipes 23 into the jets 27 and subjected to impact with the vapours. Water or hydrogen may be also added to the jets. Fresh oil is admitted by a float-controlled valve 7. The heated oil is passed by a pump 16 into the still 1 by a pipe 34 which discharges through a number of nozzles 35 in the rear header of the still to promote circulation of the oil through the furnaceheated tubes of the still. A propeller 36 may also be used for this purpose. A pressure of 75-100 lb. per sq. in. and a temperature of 700-800‹ F. may be maintained in the still 1. The furnace comprises an oil-burner 40 directed downwards and a partition 42 having a passage 45 below it. This passage is normally closed by bricks 46, but if leakage of oil takes place, the oil removes the bricks 46, and flows into a pipe 43 where it forms a seal which cuts off the draft. A weighted valve 47 in the furnace flue is held open by a plug of wood or other material which is destroyed when the temperature of the flue gases is excessive, and allows the valve to close.

Title: Moulded articles comprising polystyrene
Inventor: OAK ERNEST WHITE
IPC: C08J9/236
Filed: 1961-09-07
Abstract: Moulded articles comprising polystyrene are made by coating particles of expanded polystyrene, preferably beads or kibbled pieces, with a liquid isocyanate - terminated prepolymer capable of forming a solid polyurethane by reaction with a chain-extending agent, especially water or water vapour, placing the coated particles in a mould or cavity, which may have a suitable release coating and there forming the solid polyurethane by reacting the pre-polymer of the coating with a chain-extending agent, e.g. by subjecting the mixture to the action of either steam or a gas substantially saturated with water vapour, so that the steam or water vapour reacts with the pre-polymer to form the solid polyurethane.  The pre-polymer is preferably derived from an aromatic diisocyanate and a poly-oxyalkylene glycol of molecular weight between 2000 and 4000. Instead of a pre-polymer, the polystyrene particles may be coated with a mixture of monomers which, under the action of a chainextending agent, will form the solid polyurethane. In Example 1, kibbled expanded polystyrene material was mixed with a liquid polyurethane pre-polymer made from tolylene diisocyanate and a propylene glycol (having a molecular weight of about 2000).  This mixture was inserted in a mould and steam introduced as the chain-extending agent.

Filed: 1920-11-16
Abstract: 153,916. Muchka, J. Dec. 3, 1917, [Convention date]. Combustion-product plant.-In a method of producing inert gas mixtures, for use in the storage of inflammable liquids, by means of an internal-combustion engine, the expansion stroke is performed in such a manner that the pressure of the burnt gases at the end of the expansion stroke is higher than the pressure of the unburnt mixture at the end of the compression stroke, in order to prevent any unburnt gases from passing to the collecting vessel. In the engine shown, a mechanically-actuated exhaust valve k opens at the beginning of the exhaust stroke, and part of the exhaust is compressed and expelled past a loaded valve i and a pressure regulator f to a cooler and a storage vessel. The remainder escapes through the ordinary exhaust valve d. In the event of a missfire, the pressure does not rise sufficiently to allow the unburnt gases to pass the loaded valve i. In a modification, the valve k is replaced by a spring-loaded valve and the valve i is omitted.
