Title: Method for preparaing heterocyclic nitrogen compounds and catalyst therefor
IPC: B01J23/86
Filed: 1961-06-08
Abstract: A physically-stable performed catalytic composition resistant to softening by water, ammonia or mixtures thereof, comprises, on an oxidefree basis, 60-85 mole per cent of nickel, 14-37 mole per cent of copper and 1-5 mole per cent of chromium.  The composition contains at least 30% by weight of reduced nickel.  The catalyst is produced by compressing or extruding into pellets a finely-divided mixture of the metal oxides, prepared according to known methods, in the required proportions with or without a dye lubricant, and passing hydrogen over or through the mixture at 250 DEG -400 DEG C. preferably 300 DEG -320 DEG C., until the weight per cent of metallic nickel therein is at least 30, preferably at least 35%. The catalyst is used to prepare heterocyclic nitrogen compounds, e.g. piperazine, morpholine and C- alkyl derivatives thereof.  In the continuous preparation of such compounds, ammonia, with or without water or hydrogen, is passed over the catalyst at, e.g. 150 DEG -400 DEG C. and super-atmosphere pressure, together with compounds of formula <FORM:0931633/III/1> where X is -OH or NH2, each R is hydrogen or a lower alkyl radical, and Y is X, <FORM:0931633/III/2>ALSO:Heterocyclic nitrogen compounds, e.g. piperazine, morpholine and C-alkyl derivatives thereof are made by passing ammonia with or without water or hydrogen over a hydrogenation catalyst at raised temperature and superatmospheric pressure, together with compounds of formula <FORM:0931633/IV(a)/1> where X is -OH or -NH2, R is -H or an alkyl radical containing 1-4 carbon atoms, and Y is X, <FORM:0931633/IV(a)/2> , or <FORM:0931633/IV(a)/3> In the preferred process, the temperature is 150-400 DEG C., hydrogen is used, and the proportion of ammonia is in excess of said compound in a mole ratio of up to 5:1.

Title: Improvements in ignition systems for internal combustion engines
IPC: F02P3/02
Filed: 1947-07-31
Abstract: 641,479. Ignition systems. AMERICAN BOSCH CORPORATION. July 31, 1947, No. 20754. Convention date, April 7, 1945. [Class 7(iv)] In an ignition system for internalcombustion engines, having spaced terminals connectable in circuit with magnetos of the system and shielding or screening means for portions of the ignition systems, the shielding means comprises a housing 31 provided in a casing 14 having a plurality of .coils 18 therein, the housing 31 enclosing a plurality of terminals 27-29 each of which is connected to one of the magnetos, and a relay 19 being provided adjacent the housing 31 in the casing for operating bridging means, such as contacts 40, for bridging the contacts 37 connected to the coils 18 and contacts 34 connected to the terminals 27-29 within the housing 31. When the engine has started the relay 19 is de-energized and so breaks the circuit between the magneto coils 18 and therefore prevents any noise produced by the magnetos from being conducted through the coils to the power supply and hence to the radio apparatus. The coils 18 are used to energize the ignition systems before the magnetos have reached " cutting-in " speed. The Specification as open to inspection under Sect. 91 states that the coils could be replaced by a reactor or vibrator type starting unit or by a remote control for a magneto primary circuit or grounding relay. This subject-matter does not appear in the Specification as accepted.

[Class 38 (v)] A time switch comprises a lever 7 pivoted at 6 and having a double contact 10 movable between fixed contacts 8, 9, a snap-action being provided by a permanent magnet 20 and armature 19. The lever 7 is moved from the position shown by the engagement of a clockdriven arm 14 with an insulating cam surface 12 on the lever 7. The return movement is effected by a pin 16 on a second clock-driven arm 15 engaging a second cam surface 13 on the lever 7. A second pin 17 on arm 15 rotates a star-wheel 27 having seven spokes so that once a week, a pin 26 inserted into any one of the spokes tilts a lever 21 pivoted at 22 to separate contacts 23, 24 in series with contact 10, thus putting the switch out of action for one day of each week. The switch is stated to be useful for controlling the energization of a relay described in Specification 291,494, [Class 38 (v)].

Filed: 1923-08-17
Abstract: 216,746. Sheppard, H. B. Aug. 17, 1923. Arresting grips or friction apparatus on permanent way.-For reducing the speed of colliery pit tubs, two convergent surfaces are located one on each side of a track rail in such a manner that one surface on being engaged by a wheel of the vehicle tends to raise the wheel whereupon the weight of the vehicle tends to bring another part of the wheel into braking engagement with the other surface.

The valve 13 may be situated on the pipe 7 between the pipes 11, 10, e.g. at the position X, in which case it is arranged to open as the engine speed increases. A valve 20 is provided on the pipes 16 and is interconnected with the air valve 3 so that as one opens the other closes, the opening of the valve 20 increasing the pressure in the space 14 so that the valve 13 decreases the fuel passages 7. The valve 20 may be situated on the pipe 17. e.g. at the position Y, in which case it opens as the valve 3 opens. A valve 22 which may be controlled barometrically, may be provided on the pipe 11. The intake 24 may be supplied with gases other than air, e.g. poor gas.

Patent GB-435444-A (GB)
Title: Improvements in dyeing with vat dyestuffs
IPC: D06P1/655
Filed: 1934-03-15
Abstract: Vat dyes, dyeing with.--Dyeing in an alkaline vat is effected with the incorporation in the vat of a compound of basic reaction and stable to alkali containing tetravalent sulphur and at least one organic, preferably aliphatic radicle with at least six carbon atoms directly attached to one another.  Alternatively, the levelness of a vat dyeing may be improved by treating the vat dyed material with a blind alkaline vat containing such a compound. Such compound may be employed in the form of a salt.  Compounds containing several hydrophilic groups, e.g. amine or hydroxy groups or glycol radicles, are especially suitable.  Insoluble or insufficiently soluble compounds may be employed together with protective colloids or dispersing agents such as high molecular sulphonic acids or sulphuric esters, reaction products of alkylene oxides on organic compounds having reactive hydrogen atoms, condensation products of fatty acid chlorides with albumen degradation products, sulphite cellulose liquor and glue. Specified compounds are dimethyloctodecylsulphonium hydroxide, dipropyllaurylsulphonium bromide, and the methylsulphuric acid salts of methylethyl-cetyl- and dodecylsulphonium hydroxides. Mixtures of the compounds with the dyestuff and, if desired, the protective colloids or dispersing agents, may be prepared for addition to the vat.  In an example a mercerised bleached cotton satin is dyed in an alkaline hydrosulphite vat with Indanthrene brilliant green 4G double paste with addition per litre of the vat of 0,5 gram of strongly sulphonated castor oil and 0,05 gram of the methylsulphuric acid salt of methylethylsulphonium hydroxide. Dimethyloctodecylsulphonium hydroxide is obtained by the action of alkali on the addition product from dimethyl sulphide and octodecyl iodide.  Dipropyllaurylsulphonium bromide is obtained by combining dipropyl sulphide with dodecyl bromide.  Methylethyldodecyl - and methylethylcetyl-sulphonium hydroxides are obtained by the action of a strong base on the addition products from methylethyl sulphide and dodecyl and cetyl iodides respectively.
