Title: Improvements in the production of hydrocarbons of high boiling point range from coal, shale and other bituminous substances
IPC: C10G1/06
Filed: 1929-04-08
Abstract: 312,050. I. G. Farbenindustrie Akt.- Ges. May 18, 1928, [Convention date]. Mineral oil and waxes, extracting &c. - Lubricating-oils and other high-boiling hydrocarbons are obtained by extracting coal, shale, or other carbonaceous solid with an organic solvent, and subjecting the extracted matter to the action of reducing gases, such as hydrogen alone or mixed with carbon monoxide under such conditions that little decomposition into lower-boiling products takes place, the amount of decomposition being not more than ten per cent. The extraction may be in stages, so that paraffin wax is first separated. In an example, a paste of brown coal and a 300-350‹ C. oil obtained by destructive-hydrogenation of coal is forced through a reaction vessel at about 200 atmospheres and 380-400‹ C. until about 60 per cent of the coal is dissolved, the time of the reaction being about one hour. The entire mass is then passed over a molybdenum-zinc catalyst at 200 atmospheres and about 400‹ C. in presence of hydrogen. The condensate contains about 25 per cent of the coal in the form of lubricating oils. Or the extracted matter mav be separated from the solvent and the residue, and treated with hydrogen at pressures up to 1000 atmospheres, preferably in absence of catalysts. Reduction may be effected by hydrogen sulphide, preferably in presence of an alkaline catalyst. The lubricating oils, or portions thereof, may be chlorinated, treated with olefines in presence of catalysts such as aluminium chloride or boron fluoride, or may be treated with high-frequency electric currents maybe in presence of dispersed solids, e.g. coal, lignite, wood, charcoal, coal-ash, and colloidal or pulverulent metals or' metal oxies. Specification 283,545 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a second example in which bituminous brown coal is treated with benzene at normal or slightly increased pressure until 5-15 per cent is dissolved; the extract is cooled to - 20‹ C. to separate paraffin wax. The wax is purified by treatment with hydrogen. The residual coal is then extracted in stages of increasing pressure up to 1000 atmospheres. Other solvents specified are organic solvents, hydrocarbons containing considerable amounts of aromatic compounds and organic liquid halogen compounds. This subject-matter does not appear in the Specification as accepted.

Abstract: 614,934. Thermally-actuated valves. DENISOFF, A. C. April 9, 1946, No. 10857. [Class 135] [Also in Groups XIII and XXXVII] A hydraulic thermostat controlling a mixing valve comprises a tubular mounting member 10, two bellows 20, 30 each mounted on and sealed at one end, in axial alignment with one another, to the tubular mounting member, a movable head 21, 31 secured to the other end of each of the bellows, one bellows 30 being larger in diameter than the other and both forming part of a liquid-filled enclosure, an adjustable stop 63 associated with the movable head 31 of the bellows 30, and means for adjusting the position of said stop, the arrangement being such that on expansion of the liquid in the enclosure the head 31 of the bellows of large diameter moves until it engages the adjustable stop 63, whereat the head 21 of the bellows of smaller diameter is moved. The bellows 20 of smaller diameter is housed within, and spaced from the wall of the tubular mounting member 10 which provides a stop for the movable head 21 of the bellows and a spring 24 or other resilient means urges the said head against the stop. A spring 32 urges the larger bellows 30 to the contracted position. The adjustable stop 63 is resilient due to a spring which bears upon it and which is contained in the adjusting knob. The liquid-filled enclosure comprises the spaces inside the bellows 30 and outside the bellows 20. The two spaces inter communicate through the bore 12 and a channel on the top of the head 21 and are connected to a bulb 41. Compensating means for local temperature variations may be provided comprising two deformable chambers mechanically coupled so that they expand and contract together. The space within a bellows 74 is one of these deformable chambers and is connected to the space outside the bellows 20 by a pipe 77, the space within the tubular member 70 and externally of both bellows 73 and 74 is the other deformable chamber and may be connected to a shadow pipe 78, which extends along the length of pipe 77 and incorporates a reservoir 79. Variations in temperature along the pipe-line 77 cause the bellows 74 to expand or contract to accommodate any alteration in the volume of the liquid in the said pipe-line. Excess pressure in the system is relieved by the spring 76. In some applications, the shadow pipe 78 may be dispensed with, whilst in other applications the bulb 41 is not fitted.

Title: Barbiturate pharmaceutical preparations
IPC: A61K45/00
Filed: 1956-04-12
Abstract: A pharmaceutical preparation, which may take the form of tablets, capsules or elixirs, comprises a medicinal barbiturate and a proportion of b ,b -methyl ethyl glutarimide insufficient to interfere with a therapeutic dose of barbiturate but sufficient to overcome the toxic effects of overdose.  The glutarimide is present in the proportion of 5 to 30 per cent by weight of the barbiturate. Examples of suitable barbiturates are phenobarbitone, amylobarbitone, butobarbitone, pentobarbitone sodium, quinalbarbitone sodium or hexobarbitone sodium, and when a long acting barbiturate such as phenobarbitone is used the preparation may embody an agent that will delay the release of the b ,b -methyl ethyl glutarimide in the gastro-intestinal tract, such an agent may be cellulose acetate phthalate.  Clinical trials with animals and humans using barbiturate dosages of from 15 to 100 mgm. show no significant difference in the sleeping times whether b ,b -methyl ethyl glutarimide is present or not, but in trials using dosages of barbiturates that normally produce a coma lasting 30 to 36 hours, e.g. 2 gms. of phenobarbitone or 1.3 gms. of pentobarbitone, the sleeping time was reduced to about 6 to 8 hours and vital body functions such as blood pressure were not seriously depressed, if 15 to 20 per cent by weight of the glutarimide was contained in the preparations administered.  The preparations may also contain stimulants such as caffeine or amphetamine, mild sedatives such as sodium bromide, hypnotics such as chloral or paraldehyde, analgesics such as aspirin, phenacetin or codeine, antiasthamatics such as ephedrine, anticholinergics such as atropine, or anticonvulsants such as hydantoins.
