Filed: 1952-10-31
Abstract: 740,459. Change-speed control. LEYLAND MOTORS, Ltd. Nov. 2, 1953 [Oct. 31, 1952], No. 27501/52. Class 80(2) [Also in Group XXIX] A selector-valve assembly for controlling pneumatic or hydraulic servomotors applying brake-bands of a planetary change-speed gear on a motor vehicle, comprises a group of valves 11, one for each servo, actuated through levers 26, 27, 28, rocked about a common fixed pivot 29 by a universally mounted shift-lever 31 guided in a slotted gate 6. In their upper position, shown, the valves 11 exhaust the servo passages 45 past seats 12, 18 to an outlet chamber 24, whilst actuation of a lever 26, 28 depresses a corresponding sealed plunger 19, closing the exhaust 12, 18 and depressing the valve 11 to open a pressure inlet 17 past a seat 13, 14 to the servo passage 45. Selection amongst the levers 26, 28 is by cross-shift movement of the shift-lever 31 through the gate 6 (laterally of Fig. 2), about a pivot 32 carried in a transversely pivoted gimbal ring 34, which the shift-lever turns when' rocked fore and aft (laterally of Fig. 3), to rock a selected lever 26, 28 in one direction or the other to actuate one of the valves 11. The lower end of the shiftlever 31 carries a roller 42 which engages central depressions 44 in the levers 26, 28 in their neutral positions, and rolls on spherical surfaces 43 on the levers concentric with the pivot of the shift-lever to actuate them. Various safety obstructions are provided for the shift-lever 31 as follows. Cross-shift to the right of Fig. 2, to select the reverse valve lever 26, which is single-armed, is obstructed by a gateboss 39 until a spring-pressed sleeve 36 is raised. The lever 31 can be locked in neutral by lowering a pivoted forked latch 41. Release of the neutral lock may be by depression of the knob on the shiftlever. In Figs. 5 and 6, not shown, in addition to the necessity for raising an external sleeve to free reverse passage, it is also necessary, before any of the four forward speeds can be engaged, to push down the lever-knob, which is carried on a slotted sleeve, a collar on which is thereby cleared from a fixed obstruction surrounding the lever. In a further modification, not shown, the lever knob is attached to a sleeve by a cross-pin, which to free reverse, is lifted out of a slot in the end of the shift lever, and turned to rest in a groove therein, in which position engagement of forward gears is obstructed.

Hinged annular baffles 13, 14 under the control of the pilot are arranged in the space between the fuselage 4 and an open-ended guide cylinder 12 in such a manner that when closed they direct the slipstream from the airscrew 6 to the intake 11 of the turbine 9. When the baffles 13, 14 are open they lie parallel with the guide cylinder and fuselage respectively permitting the free passage of air therebetween. Alternatively one or more baffles arranged to direct the slipstream directly to the lifting airscrew may be employed in lieu of the air turbine. When more than one lifting airscrew is provided they are arranged symmetrically about the longitudinal axis of the aeroplane. Specification 28907/10 is referred to.

Title: Improvements in or relating to the evaporation of water from concentrated solutions of calcium nitrate
Inventor: AKEN JOHANNES S A J M VAN
IPC: C01B21/46
Filed: 1946-09-16
Abstract: A saturated or nearly saturated aqueous solution of calcium nitrate is heated under a pressure high enough to prevent boiling and then expanded to a pressure below the vapour pressure of the heated solution before the expansion.  The expansion gives rise to violent evaporation and a pasty mass containing solid calcium nitrate is formed.  This pasty mass is preferably dried by mixing it with dry calcium nitrate, i.e. part of the final product, so that the mixture contains less than 10 per cent water and then using a drying drum. Calcium <PICT:0632580/III/1> nitrate solution containing 45 per cent water is concentrated in evaporator 1, and the concentrated solution (25.5 per cent water) is stored in tank 2.  The concentrated solution is pumped through tube-furnace 4 where it is heated to 260 DEG  C. under a pressure of 19 atm., and is then injected tangentially against the wall of vessel 6 which is at atmospheric pressure.  The solution descends along the wall in a helical line and a pasty mass containing 14.7 p  per cent water discharges from the bottom of vessel 6 into trough 7 where it is mixed with dry calcium nitrate introduced at 8, the ratio of salt to paste being 11 to 10.  The mixture is dried in drum 9 at about 230 DEG  C., and the solid obtained which contains 1.5 per cent water, is cooled in drum 10. The solid is separated into three fractions by sieves 11, 12, and the middle fraction of grain size between 3 to 4 mm. constitutes the final product.  The mixture of the coarser and finer fractions, the former after being ground by mill 13, introduced into trough 7.
