Title: Method and device for distilling aqueous salt solutions to obtain potash water
IPC: C02F1/14
Filed: 1954-12-02
Abstract: Pure water is obtained from sea water and other aqueous salt solutions by bringing a spray or jet of the preheated aqueous solution into contact with a hot gas such as air, under subatmospheric pressure, whereby partial evaporation of the water takes place, compressing and independently heating at least part of the mixture of water-vapour and gas so obtained and then passing the hot compressed mixture in heat-exchange relationship with fresh solution and gas whereby the solution and the gas are heated while the water-vapour condenses from the mixture to yield pure water.  In the apparatus shown, the aqueous solutionis pumped in through conduit 23a; and air is sucked into manifold 20 by blower 22.  The aqueous solution flows up through radiator 13 which forms the <PICT:0780272/III/1> inner path of triple-path heat-exchanger 12, which surrounds cylindrical evaporating chamber 1.  The air rises through the outer annular path 17 of the heat-exchanger, while hot compressed water-vapour/air mixture (see later) flows down in the intermediate path between the two up-flow paths.  The solution, now at a temperature between 85 DEG  and 212 DEG  F., passes through duct 3 which delivers it as a jet into chamber 1.  The preheated air, which has a temperature between 100 DEG  and 250 DEG  F., is introduced into the lower part of the chamber through duct 4. Partial evaporation of the downflowing solution takes place as it falls through the upflowing air.  Part of the mixture of water-vapour and air is drawn from the chamber through stack 6a into rotary compressor 7a; and the compressed mixture discharged therefrom is heated by gas burners 8.  The remainder of the moist air in chamber 1 is withdrawn through stacks 7, and mixes with the hot compressed portion in the throats of convergent-divergent systems 8a.  All the moist air, which is now hot and compressed, is collected in duct 10 and then delivered by ducts 11 to the heat-exchanger.  The pure water condensed in the heat-exchanger collects in annular chamber 31, from which air escapes as shown by arrows 29.  Non-evaporated solution is discharged from the apparatus via valve 33.  Another embodiment is described wherein the water-vapour/air mixture may be heated by solar energy, the cooling of the mixture is effected in two separate heat-exchangers, and a third heat-exchanger is provided wherein the solution to be treated is preheated by the concentrated solution leaving the apparatus.  Specification 760,517 is referred to.

Abstract: 736,850. Jigging shoots. RHEINISCHWESTFALISCHE KALKWERKE, and MASCHINENFABRIK A. CLAUS. Dec. 17, 1953 [Dec. 24, 1952], No. 35186/53. Class 78 (1). In an arrangement for supplying pulverulent, granular or lumpy material to, or extracting it from, chambers under superatmospheric or subatmospheric pressure of the kind provided with air-locks having shut-off members which are opened and closed successively, the material is conveyed within the air-lock chambers by jigging shoots. The outlet 3 of the hopper 2 is closed by a jigging shoot 4 which is mounted on two pairs of rubber buffers secured respectively to the side walls of the upper air-lock chamber 6 and to a base plate 10. A tubular member 11 attached to the shoot passes through an aperture in the upturned end of the plate 10 and carries a vibrator 13. Air is prevented from entering the chamber 6 through the aperture by a gasket 12. A flap 5 pivoted at 14 seals off the chamber 6 from an air-lock chamber 16. A jigging shoot 17 mounted at the bottom of the chamber 16 is constructed similarly to the shoot 4. A pivoted flap 18 seals the chamber 16 from the atmosphere. Means is provided for actuating the vibrators 13, 20 and the flaps 5, 18 in timed sequence. The flaps are actuated by compressed air supplied by a compressor 30, Fig. 3, which is driven through worm gearing 28 by a motor 27. The worm gearing drives also a control disc 32 on opposite sides of which are mounted fixed toothed segments 33, 35 and adjustable toothed segments 34, 36. The segments 33, 34 rotate the gear wheel 37 of a change-over cock 39 twice through an angle of 90 degrees during one rotation of the disc 32 and the other segments rotate similarly the gear wheel 38 of a change-over cock 40. The gears 37, 38 are provided with cam segments 57, 63 which actuate the switches 58, 64 controlling the vibrators 13, 20. The cocks 39, 40 control the admission of air to and exhaust from pairs of cylinders 44, 48, the pistons of which actuate the flaps 5, 18.

Title: Drive system control devices
IPC: B60W30/18
Filed: 1974-08-09
Abstract: 1483604 Hydrostatic transmission control; linkwork LINDE AG 9 Aug 1974 [13 Aug 1973] 35209/74 Headings F2W and F2K In a control linkage for a motor vehicle hydrostatic transmission having an engine driven variable displacement pump wherein a pump displacement adjusting pedal 1 acts additionally through a linkage 5 ... 11 on an engine fuel control rod 13 to increase fuel supply in proportion to pedal depression, a servo 15 adjusts the fuel control linkage to increase fuel supply when the load on the transmission exceeds a predetermined value. As shown a pair of pump displacement adjusting pedals 1, 2 for forward and reverse drive respectively are interconnected so that depression of one pedal causes the other pedal to rise and vice versa. The rising pedal normally acts through a bar 5, lever 6, rod 9 and lost motion connection 10, 12 on the engine fuel control rod 13. The servo 15 is connected by a line 16 including a throttle to the pump delivery line so that when the load on the transmission exceeds the predetermined value the accompanying rise in pump delivery pressure is transmitted to the servo 15 which moves a piston rod 14 and the pivot 7 of the lever 6 downwardly to increase fuel supply. When the fuel supply reaches its maximum value further actuation of the servo 15 acts through the linkage on the pedals to reduce pump displacement. In a modification the engine fuel supply is increased on overload by the servo adjusting the point of contact of the bar 5 with arms 3, 4 of the pedals 1, 2. This may be effected by adjusting the position of the pivot 7, lengthening the lever arm 6 between the pivot 7 and bar 5, or by adjusting the position of the axis about which the pedals pivot.
