Abstract: Mononuclear aromatic nitro-compounds are crystallized from nitric acid of 55 to 68 per cent concentration in a quantity insufficient for a complete dissolution of the nitro-compounds during any part of the crystallization.  The crude product of a nitration process may be mixed with the nitric acid in a small mixing vessel, where incipient crystallization occurs, and allowed to run into a larger vessel where the mixture is maintained at a lower temperature, crystals being separated by filtration or centrifuging.  The mixture of nitro-compound and nitric acid may also be passed continuously through a series of three vessels at progressively decreasing temperatures, the final slurry being continuously taken to a filter or centrifuge; the mother liquor may then be cooled to a still lower temperature to obtain further crystals, which are returned to the mixing stage as such, or in solution in the nitric acid added thereto.  In examples crude products are treated to obtain (1 to 5) 2,4,6-trinitroluene, (6) a dinitrochlorobenzene product (2,4- and 2,6-dinitrochlorobenzenes), and (7) m-dinitrobenzene.ALSO:A method of crystallizing mononuclear aromatic nitro-compounds, particularly di- and tri-nitro compounds, from nitric acid, is characterized in that acid of 55 to 68 per cent. concentration is used and in a quantity that is insufficient for a complete dissolution of the nitro-compounds during any part of the crystallization.

Abstract: 1,018,509. Gyroscopic apparatus. AGA A.B. Oct. 30, 1962 [Dec. 12, 1961], No. 40971/62. Heading G1C. A gyro rotor 10 is suspended in inner and outer gimbals 11, 12, a constant torque being applied to the gimbal 11 by a spring 16, causing the other gimbal 12 to precess, constancy of the speed of precession and thus of a given equilibrium angle between the spin axis of the rotor 21 and the axis 14 of the outer gimbal being maintained by a torque motor 17 adapted to apply correcting torques to the precessing gimbal 12 under the control of a pick-off 19 which senses deviations from the equilibrium angle,the arrangement being such that at the equilibrium angle the derivative with respect to this angle of the moment of the spring force about the axis of the gimbal 11 is equal to the derivative with respect to the equilibrium angle of the moment of precession of the gimbal 12. The output from the pick-off 19 is fed by way of an amplifier 18 to the torque motor 17 to maintain the desired equilibrium angle. The spring 16 acts about the axis 13 of the gimbal 11 and is arranged to be symmetrical about this axis. Several suitable arrangements are described in the Specification. In Fig. 7 two springs 42, 43 are used and these act on pivoted arms 37.38 and through links 35, 36 to act on an extension 34 on the shaft of the gimbal 11. The arms may be connected to torsion bars of quatz in place of the springs 42, 43; and four torsion bars may be provided if desired. In Fig. 8 (not shown), two springs 48, 49 act on the shaft of the gimbal 11 through wires 44, 45. The gyro may be made of a metal alloy having a low coefficient of thermal expansion to offset changes in rotor speed with temperature.

Each (or one) lower link 3 is pivoted at 8 to a rocker 4 pivoted on a shaft 5 carried by the tractor, the rocker 4 when in a locked position (as shown in full line) bearing on a stop and being retained in that position by an automatic locking mechanism which is releasable by the tractor driver's foot to allow the lower link(s) 3 to move away from the tractor (to the phantom position) to facilitate coupling to an implement. In the Figs. 1 and 2 embodiment, each lower link 3 is pivoted to a separate rocker 4 normally bearing on a stop plate 6, and the locking mechanism comprises a spring-loaded pin 13 engaging a bore 14 in the stop plate 6. A U-shaped release lever 15 is pivoted to the pin 13 and is movable in the direction of the arrow (Fig. 2) by the driver's foot to extract the pin 13 from the bore 14 and also swing the rocker 4 (until stops 11 abut) and hence move the lower link 3 towards the implement. A strut (not shown) for preventing lateral movement of the lower link 3 is pivoted at 9 or 10 to the rocker 4. In another embodiment, only one lower link 3 is pivoted to a single rocker 4 normally bearing on a stop pin extending from the shaft 5, and the locking mechanism comprises a spring-loaded pin 13 engaging a recess in the shaft 5 and released by pressure on its end. A lever is non-rotatably mounted on the shaft 5 and engages a spring opposing rotation of the shaft produced by draught forces in the lower link 3, the lever being linked to the control device of the hydraulic lifting gear, to provide draught control.

Abstract: 1,234,094. Lasers. PERKIN-ELMER CORP. 26 July, 1968 [26 July, 1967], No. 35870/68. Heading H1C. In an inert gas laser in which the inert gas flows through a discharge tube provided with an anode and cathode for maintaining a discharge the cathode includes electron emissive material which when bombarded by ions from the discharge emits electrons which excite ions in the discharge to produce a population inversion. Argon, krypton, xenon, helium or neon is introduced into glass enclosure 10 through gas inlet 28 and hollow cathode 20 of tantalum, tungsten or other thermionic emitter and is removed from outlet 29. In operation a D.C. field is provided between the anode 19 and cathode 20 and a discharge is initiated by establishing a temporary RF field in the gas stream which discharge is restricted to an axial path between the anode and the cathode by discs 32 of thermally conductive material apertured at the centre and at the circumference and is also subjected to a magnetic field from solenoid 30 or a permanent magnet. Ions from the discharge re-enter the cathode 20 against the flow direction of the gas and strike its intemal surface thereby heating the cathode to emit electrons which are accelerated into the discharge region and collide with the ions to excite them to a raised energy level and form an inverted population. The discharge may be started with argon and then argon is replaced by another gas for lasing purposes. Reflected shield 31 reduces radiative heat loss and sputtering damage.

Abstract: 1288707 Stratified fuel charges; charging under pressure; purifying exhaust; heating charge P AUGUST 19 April 1971 [17 Dec 1970] 22798/71 Heading F1B An I.C. engine has two carburetters or injection devices for supplying mixtures of different richness in different paths with a phase displacement therebetween to a cylinder with a sparking plug, the path adjacent the sparking plug having a pressure device for introducing the richer mixture only when the cylinder has been charged with fresh gas or combustion air to give a multilayer charge with the ignitable richer mixture in the region of the spark-plug and with air excess in the whole mixture. When the engine operates in the lower and middle speed and load ranges an engine-driven rotary compressor 13 draws rich mixture from a carburetter 10 which is downstream of a filter 12. The piston induces combustion air from a carburetter along passages 15, 17 to ports 3 to scavenge the burnt gases which leave via port 4. As the air is compressed by the rising piston the valve 9 is rotated to admit the rich mixture, which has been heated by a baffle plate 26, to form a rich layer in the region of the spark-plug 8. Exhaust gas may be mixed with air from the carburetter in the idling and low speed and load ranges. In the middle to upper speed and load range the carburetter 11 supplies a weak mixture which is enriched at full load. Exhaust gas passes through an afterburner 18 having a main passage 25 containing a control flap 19 and a surrounding afterburner chamber 22 which may contain a catalyst. Exhaust gas passes via passages 20 and the afterburner 22 to mix with exhaust gas from passage 25 in chamber 24. In the lower speed range the closed flap 19 directs all the exhaust gas through the afterburner and progressively reduces this as speed increases so that at full load 85-90% of the exhaust gas passes straight down passage 25. The engine may be a four-stroke or rotary piston engine. The carburetters may be replaced by two fuel injection systems.
