Title: Improvements in the manufacture and production of amino-ketones
Filed: 1938-02-03
Abstract: 510,876. Amino ketones. JOHNSON, G. W. (I.G. Farbenindustrie Akt.-Ges.). Feb. 3, 1938, Nos. 3400 and 7878. Class 2(iii)] Amino ketones are obtained by the action of. water in an acid medium on amines containing an amino group in alpha-position to an acetylenic linkage; the quaternary ammonium compounds obtainable from such amines may also be treated. Suitable amines are obtainable by the action of acetylene on ammonia or amines, as described in Specification 510,457, or, as described in Specification 510,904, by the action of acetylene on the reaction products of aldehydes or ketones with ammonia or organic compounds containing a group NH of NH2. The quaternary ammonium compounds of the acetylenic amines are obtainable by treating the amines with alkyl or aralkyl esters of mineral acids, e.g. with alkyl halides or dialkyl sulphates. The addition of water to the acetylenic amines or quaternary ammonium compounds may be effected in the presence of a mineral acid at a temperature up to about 100‹C. in the presence or absence of-a catalyst, e.g. a compound of a heavy metal of the first or second periodic group. In the examples, (1) an amine obtained from diethylamine and acetylene, as described in Specification 510,457, is added to aqueous sulphuric acid to which mercury oxide has been added ; 3-diethylamino-2-butanone is obtained; (2) 3-dicyclohexylaminobutine-l (from dicyclohexylamine and acetylene) similarly yields 3-dicyclohexylamino-2-butanone; (3)dimethylpropargylamine similarly yields dimethylaminoacetone. Reference is made also to the treatment of acetylenic amines which contain an arylkyl radicle linked to the nitrogen atom or in which the nitrogen atom forms part of a heterocyclic ring. The reaction of the products with phenylhydrazine and semicarbazide is also mentioned.

Abstract: 695,628. Radiators for space heating. RICHINGS, J. W. Feb. 9, 1951 [Feb. 13, 1950] No. 3572/50. Class 64 (ii) . A self-contained space heater, of the kind comprising a hollow body in which the active medium circulates, is provided with a passageway, or a set of passageways which do not communicate with each other between their ends, the or each passageway formming a closed loop arranged in a vertical plane to enable the liquid to circulate by a thermo-siphon action. The passageways communicate at their lowest points with heating means 19 and the quantity of fluid employed is such that in its liquid state, shown at 20, it is sufficient to cover the heating means. In the construction shown, the heater comprises two similar side plates 10, 11 each so pressed as to provide a plurality of open sided channels whereby they form, on assembly, a single passageway for the fluid. The fluid passes from the heating means 19 through portions 12, 16 of this passage and then takes the zig-zag path 13 bounded by walls 18. An auxiliary chamber 23 in communication with the lower end 32 of the downflow section 13 assists the circulaton when starting up from cold. The heater has a temperature-sensitive device 22 capable of regulating the input of electric power to the heating means 19. In a modification, one of the plates 10 or 11 I is flat, and in another modification a flat plate is interposed between the two plates shown to provide two separate passageways which do not communicate with one another except near the heating means.

Title: Improvements in and relating to the direct catalytic hydration of olefines to alcohols
Inventor: TAYLOR ARTHUR WILLIAM CHARLES
IPC: C07C29/04
Filed: 1952-02-20
Abstract: Monohydric alcohols are made in a continuous process by passing water and a mono-olefine of 2-4 carbon atoms in the molecule into a suspension in an aqueous liquid medium of a hydration catalyst containing an oxide of tungsten, maintaining the reaction mixture at elevated temperature and pressure, withdrawing liquid from the reaction zone and treating it for the recovery of the desired alcohol.  Mixtures of the olefines may also be used.  The blue oxide of tungsten is preferred and may be made in situ by the reduction of tungsten trioxide.  Tungsten di- and tri-oxides are also specified. The catalyst may be in granules or small pieces but is preferably used as a powder. Temperatures of 150-350 DEG  C. are mentioned preferred for ethylene being 280-310 DEG  C., for propylene 250-290 DEG  C. and for iso- and n-butylenes 160-220 DEG  C. and 230-270 DEG C. respectively.  Pressures of about 250 atmospheres are satisfactory.  Desirably all of the catalyst suspension remains in the reaction space and filtering means for effecting this condition are described.  A number of converters may be used in parallel, the catalyst being maintained in suspension by the flow of reactants.  In examples suitable apparatus is described and propylene, isobutene and n-butene are hydrated to isopropanol, tert.-butanol and sec.-butanol respectively using blue oxide of tungsten as catalyst obtained by reduction of an initial charge of commercial tungstic acid.

Title: Turbine and motor driving mechanism for rotary pumps used in steam heating systems
IPC: F24D1/00
Filed: 1932-02-15
Abstract: 381,817. Pumping systems ; steamheating systems. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Nash Engineering Co. ; South Norwalk, Connecticut, U.S.A.) Feb. 15, 1932, No. 4490. [Class 110 (i).] In a steam-heating system, a differential valve is provided in the steam supply line for maintaining a differential of pressure between the steam supply and the heating system, vacuum being maintained in the system by a rotary pump, driven by a low-pressure steam turbine which is operated by said differential of pressure and by auxiliary pumping means which is thrown into or out of operation by means controlled from said differential of pressure. A is a tank for the returns from the system connected with an auxiliary pumping unit driven by an electric motor G. Vacuum and float control H, I for the motor are provided as described in Specification 200,150, [Class 110 (i), Centrifugal and screw fans &c.]. Also connected to the tank is the main pump P driven by a steam turbine F operating with the steam used in the heating system as described in Specification 329,884, [Class 64 (ii), Heating systems &c.]. The steam passing from the boiler to the heating system is led through a differential valve W comprising two valves 10 on a common stem 11 which extends into a casing 12 and carries a plate 13 giving a dashpot action. The upper valve is slightly larger so that the steam pressure normally tends to lift the valves, and a small adjustable differential of pressure, say 2-3 lbs. per sq. in., can be obtained between the inlet and outlet side of the valve by means of weights 14 placed on the stem 11, and is used to operate the turbine as described in the last-mentioned Specification. A casing 15 holds a diaphragm 16 above which steam from the boiler is admitted by a pipe 17 and below which a pipe 18 admits steam which has passed the valve W. The diaphragm 16 is carried by a hub 19 mounted on a supplementary diaphragm 20 which engages studs 21 carrying a ring 22 connected by a yoke 23 to operate an electric switch E. When there is an insufficient differential of pressure across the valve W, the diaphragms are forced downwards by spring 25 arranged on a shaft 24 and adjustable by means 'of a nut 26. The electric motor G is therefore put into circuit to operate the auxiliary pump. The invention is applicable to any rotary condensate pump used in connection with a steam-heating system.
