Abstract: 708,114. Electronic counting apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 6, 1950 [July 15, 1949], No. 16898/50. Class 106 (1). [Also in Group XL(a)] A counting circuit comprises a cold cathode gaseous discharge tube (see Group XL(a)), having a toroidal glass envelope 14 containing a ring anode 15, connected to the positive pole of a battery 7, and ten cathodes 16 to 25 each having a resistance-capacity network 10, 11 connected through a limiting resistance 8 to the negative pole of battery 7. Opening and closing the switch 12 causes a discharge at the index cathode 16. Pulses applied at the input terminals 16' with polarity as shown cause the discharge to extend along the cathode and transfer to the successive clockwise cathode for each pulse until on the tenth pulse the discharge returns to cathode 16, thus causing a transient voltage pulse to pass through coupling condenser 38 and appear across the output terminals 17<SP>1</SP>. This output pulse may be passed to a second tube for cascade operation. The envelope may be cylindrical in which case the anode is a disc, or the cathode may be arranged in a linear array opposite a rod anode.

Title: Improvements in or relating to the preparation of pyrotechnic compositions
IPC: C06B21/00
Filed: 1944-09-05
Abstract: A pyrotechnic composition which is compressed during charging and before use and comprising an oxygen carrying body such as red lead and a finally divided metal such as magnesium powder formed into a paste by means of a solution of an inflammable colloid such as colophony or nitrocellulose in an organic solvent until each particle of the composition is completely moistened by the solution, is separated by screening into separate lumps and the solvent driven off by evaporation.  The grains are thus coated with colloid and slide freely in the charging devices and are protected from the atmosphere. The colloid is liquefied during compression in the charging device and renders the mass fluid tight.  The organic solvent is preferably anhydrated and of low boiling point.

The vehicle comprises main tracks 4 connected by cranked members 2 passing through the body 3 which can be raised' and lowered by means of pulley tackle 18. The tracks are driven by means of central spur gears 115 driven by pinions 118. The tracks pass round water-tight chambers and are tensioned by screw mechanism 24. To maintain the driving-connexion between the pinions 118 and spur gears 115 when the body is adjusted vertically, the engine and driving-gear are adjustable longitudinally by means of screw gear. The driving- shafts carrying the pinions 118 pass through sliding doors in the water-tight track casings. As shown in Fig. 11, the doors 60, 61 slide horizontally in guides and are fitted with apertures A - - M a vertically sliding panel 66 carried by the shaft lying behind the doors. The auxiliary tracks are shown in Fig. 6<a> and are mounted on the main sprockets 115 and sprockets 120.

Abstract: 334,966. Flind, H. C., and Flind, J. June 18, 1929. Movable-abutment type; cooling parts; working-fluid supply; packing drums; driving pumps. -In a geared vane type of internal combustion engine the rotating elements which divide the working space up into a number of chambers, are formed by two series of pins, each series rotating on a pitch circle of the same diameter, but with the pitch circle axes offset laterally a distance equal to the distance between the centres of each pair of pins. The two series of pins 15 and 17 are each fixed to rotating end plates 11 and 12 respectively which are borne by thrust bearings 28 and 29 on the casing cheeks 22 and 23. Bolts 24 and lugs 25 locate the position of the cheeks. Beteen each pair of pins 15 and 17 is held a partition piece 19. The elements, which always remain parallel, rotate in an anti-clockwise direction and take in fuel mixture from a supply port 35. The charge is compressed and fired by a plug 36, expands, and is exhausted through a port 37. Cooling fluid is circulated through jackets 39 and 38 in the casings, which are supplied by means of a pipe 40. A packing strip of flexible material 43, Fig. 3, is fitted to the inner casing at the point X<1>. The surfaces 44 and 45, Fig. 3, form arcs of circles which are concentric with the pitch circles of the pins 15 and 17 respectively. The pins 15 and 17 may be mounted eccentrically on further pins. Two sparking plugs may be fitted. A modified form of the apparatus for use as a steam engine, or as a steam driven pump, with two inlet and two exhaust ports is described. The Provisional Specification illustrates a spring loaded plunger which may be fitted to the outer wall of the working chamber opposite to the point X'.

Title: Improvements in or relating to dehydration of hydrazine by azeotropic distillation
IPC: B01D3/36
Filed: 1954-06-10
Abstract: <PICT:0761919/III/1> In a process of producing anhydrous hydrazine wherein aqueous hydrazine mixed with aniline is subjected to azeotropic distillation whereby the water, together with some of the aniline, passes over into the distillate, the aniline phase of which is returned to the azeotrope still as reflux, and wherein the aniline-hydrazine bottoms from the azeotrope still is fractionated to produce anhydrous hydrazine as overhead product and an aniline bottoms, the latter being recycled to the feed mixture for the azeotrope still, this still is operated at a reflux ratio in the range of 1.1:1 to 15:1 and there is maintained in the feed mixture thereto a hydrazine-water mole ratio of 0.5:1 to 2:1 and an aniline-hydrazine mole ratio of 3:1 to 12:1.  Dilute aqueous hydrazine, such as is produced by distillation of the Raschig synthesis liquor, is passed through line 11 to still 10 which is heated by reboiler 18.  Water vapour is taken off overhead from still 10, and concentrated aqueous hydrazine accumulates in reboiler 18. This concentrated hydrazine is withdrawn through line 20 and passed, together with aniline, through line 21 into still 22 which is equivalent to about 7 to 10 theoretical plates and is heated by reboiler 31. The aniline-hydrazine mole ratio in the mixture entering still 22 through line 21 is preferably about 7:1.  Vapours of aniline-water azeotrope pass from the head of still 22 and are condensed in condenser 26 which contains baffles which enable the water phase of the condensate to separate from the aniline phase. Aniline and water are returned to still 22 via line 27 in such amounts as to maintain a reflux ratio of about 4:1.  The balance of the condensate is passed through line 28 into aniline-recovery still 29 which is heated by reboiler 49.  A mixture of hydrazine and aniline containing only 0.1 to 0.7 per cent of water accumulates in reboiler 31.  This mixture is withdrawn through line 33, and passed to still 34 which is heated by reboiler 41.  Hydrazine having a purity of at least 95 per cent is withdrawn as distillate from the head of still 34.  Aniline containing 1 to 10 per cent of hydrazine is withdrawn from reboiler 41 through line 24, and the bulk of it is recycled to azeotrope still 22 via line 21.  A minor portion of the aniline is however diverted through line 43 to recovery still 29 in which it is freed from non-volatile impurities.  The aniline-water azeotrope is taken overhead from still 29 and is condensed in condenser 45.  The distillate is separated into an aniline phase and a water phase in separator 46. The water is returned to still 29 via line 48; and the aniline is recycled to azeotrope still 22 via lines 23 and 21.  Water is discharged from reboiler 49.  Specification 756,004 is referred to.
