Title: Improvements in or relating to hydraulic turbo-transmission apparatus
IPC: F16H61/56
Filed: 1934-04-30
Abstract: 431,427. Hydraulic transmission of power. BANNER, O. A., 367, North 4th Avenue, Highland Park, New Jersey, U.S.A. April 30, 1934, No. 13004. Convention date, April 28, 1933. [Class 69 (ii)] In hydraulic power transmission means comprising a pump or primary element, a turbine or secondary element, and an adjustable vane system between the pump outlet and the turbine element, the adjustable vane system can be either held at rest or coupled with one of the elements, preferably the turbine. In the form shown in Fig. 3 comprising primary and secondary wheels 1, 4, the guide vanes 15 having adjustable entrance and exit portions 14, 16, are supported by a sleeve 11, which may be held stationary by a brake acting on a drum 12, or may be coupled to the driven shaft 6 by a member 18 and a slidable member 20. The vane-adjusting means comprises a member 37 slidable and turnable on a threaded ring splined on the sleeve 11 and connected to a cam 34 adapted to actuate shafts 30 and levers 26; the latter operate a ring 23, Fig. 16, meshing with gears 24 on the vane portions 16. The gears 24 also mesh with a ring 25 having a cam surface 27 engaging pins 28 on the vane portions 14. The members 20, 37 may be actuated manually or by a power relay which may be subject to automatic control. In the latter case, they are actuated from a relay piston 39 by forks 42, 43, and a rod 44 controls the brake. A hand lever 48 acts through a rod 50, spring-pressed collar 74, and floating lever 51 to position the valve 46 of the relay cylinder. When starting a motor vehicle, the collar 74 will be prevented from full-stroke movement, even though the lever 48 is moved through its full extent, by a pivoted stop 78; the stop is later removed by differential gearing operated from the driving and driven shafts, and then the collar 74 completes its movement. The differential gearing comprises a sun-wheel 55 driven through a shaft 65 from the driving shaft, an oppositely rotating sun-wheel 56 driven through a shaft 66 from the driven shaft, and planet wheels 57, 58 in a cage 64. When the relative speeds are such that the cage reverses its direction of rotation, it moves a bar 82, Fig. 10, endwise to remove the stop 78, and to act through a lever 90 on the carburetter control to reduce the speed of the driving motor. When the relay piston reaches the end of its stroke, the lever 90 slips off the cam 89, and is returned by a spring 93 so that the motor speed is restored. An adjustable friction drive 73 may be interposed in the shaft 66, and clutches 67, 68 controlled by the rod 50 may be employed. In the form shown in Fig. 26, vanes 14<1>, 151, 16<1>, for full speed, part speed, and reverse operation are carried by an axially movable sleeve 11<1>.

Title: Process for the separation of lithium isotopes
IPC: C01D15/00
Filed: 1957-04-29
Abstract: Lithium isotopes are separated from an aqueous solution of compounds thereof by altering one or more of the parameters, pH, temperature or dilution, of the aqueous system up to, but not beyond, the point where incipient precipitation or crystallization occurs, as determinable by the Tyndall effect: thereafter the parameter is maintained unchanged until the precipitation of the fraction concerned is complete.  The parameter is then altered and a further fraction precipitated.  The fractions are enriched in Li7 and Li6 respectively.  Conditions are maintained homogeneous throughout the liquid medium by stirring. The invention is particularly concerned precipitation of lithium carbonate or phosphate from a solution of lithium complexes formed with metal complexes of di- or poly-basic organic acids, such as are described and claimed in Specification 866,718.  Al, Cr, Mo, W, U, V, Nb and Ta complexes with oxalic, citric and tartaric acids are referred to, but preferably aluminium oxalic acid is employed as the complexing agent for the lithium. According to an example, lithium carbonate was maintained in contact with aluminium oxalic acid solution at 60-80 DEG C. and the resulting solution of lithium complex was treated with ammonium carbonate solution at 70 DEG C. until crystal nuclei formed.  A fraction enriched in Li7 was obtained after several hours vigorous agitation. Further ammonium carbonate was added and a series of fractions recovered.  A further example refers to the use of aluminium citric acid as a complex-former for the lithium. Lithium phosphate is precipitated fractionally by adding ammonium phosphate.  Inoculation with crystal nuclei of salts of Li7 isotope aids precipitation.
