Counter scales and the like; spring apparatus. -An automatic or semi-automatic weighing scale, of the kind wherein the automatic resistant is in the form of one or more horizontallydisposed flexible resistant strips which are secured to a frame, is characterized in that the frame is provided at one side thereof with a counterbalancing mass, and in that means are provided for adjusting the tension of the resistant strip or strips. A connection from the pan support 9, consisting of a chain 22 and flexible ribbon 24, is attached to an annular frame 25 weighted by a counterbalancing mass 28. Two flexible resistant strips 26 are secured diametrically across the annular frame and are maintained in a state of tension by a resilient plate 27 adjustable by a screw 27b. The central portions of the flexible strips 26 are clamped between two cylindrical members 29, 30 secured to the indicator casing 32. An indicating pointer 33 is attached to the annular frame. In a modification, the plate 27 is dispensed with and the flexible strips 26 are placed under tension by means of a threaded bush or bushes adjustable within the mass 28, and the cylindrical members 29, 30 are replaced by triangularly-shaped members. Casings.-The indicator casing 32 is rotatably mounted on a tubular member 21 to which it is secured by a screwed sleeve 36 and spring washer 37.

Title: An electrically controlled variable speed-gear
IPC: H02K16/00
Filed: 1929-08-03
Abstract: 337,464. Casson, W., and Roberts, H. Aug. 3, 1929. Electromagnetic clutches.-The invention relates to power transmission devices comprising a dynamo-electric machine having an armature and field magnet, one of these elements being connected to the driving shaft and the other to the driven member, means being provided to vary the magnetic flux so as to vary the power transmitted. According to the invention, epicyclic gearing serving as a driving connection between the driving shaft and the dynamo-electric element not coupled to the driven shaft is such that when the driven shaft element is stationary or rotating at low speed, the first mentioned dynamo-electric element is driven in the opposite direction to the driving shaft. The Figure shows a machine of the continuous-current series generator type in which the field magnet 15 which is rigidly connected to the driven shaft 10 carries differential field windings 20, 21 which are directly connected to the commutator brush 17 on one side and connected separately at their other ends through rheostats 31, 32 to the fixed casing 11 which is in electrical connection with the other commutator brush 18. The driving shaft 1 carries a sun pinion 2 which meshes with planet pinions 3. The, pinions 3 mesh with complementary pinions 3a engaging with a sun pinion 4 on the armature shaft. The spindles 5 of the planet pinions 3, 3a are mounted in a housing 6 fixed to the magnet yoke casing 7. In operation, when the field magnet is held, the armature will rotate in the opposite direction to the driving shaft 1. The fluxes set up by the current generated tend to cause the armature and field to rotate together so that on light loads the two members rotate in the same direction as the driving shaft. As the load on the shaft 10 increases and the field member slows down, the armature also slows down, stops and finally reverses its direction of rotation. In a modification, the armature carries a squirrel cage winding and the field member a single exciting winding fed from a separate source. Continuous current from an external source may be fed to the field magnet winding or to an auxiliary field winding in the arrangement shown in Fig. 1. A number of transmission units may be employed in combination, the driven shaft of the first being connected to the driving shaft of the next unit.

Title: Enrichment of isotopes of lithium
IPC: B01D59/32
Filed: 1965-06-04
Abstract: <PICT:1115929/C1/1> A process for enriching lithium isotopes by selective distribution into two liquids which are in contact with each other, comprises contacting lithium amalgam with a solution of a lithium salt in at least one organic amine solvent with a boiling point below 100 DEG  C., e.g. propylamine, isopropylamine and ethylamine.  In practice, the lithium amalgam is fed into the top end of an exchange column 1 and is contacted with a solution of the lithium salt in the organic amine, which salt is derived from an ion exchange reaction in the lower part 13 of the column between the lithium amalgam and a less basic auxiliary salt solution, e.g. CdCl2, CdBr2, ZnBr2 or HgCl2 supplied to the bottom of the column 1 from a column 4.  The auxiliary salt solution, e.g. CdCl2 is diluted with recycled amine so as to be present in slightly less than the quantity of lithium supplied.  The remaining lithium amalgam, withdrawn together with the cadmium amalgam, is exchanged in a column 2 with further cadmium chloride supplied from a column 5.  The cadmium amalgam from this column is reacted in a column 3 with hydrochloric acid to liberate mercury and recover cadmium chloride which is recycled to the columns 4 and 5.  The mercury is cycled to an electrolysis apparatus 9 where it is converted to lithium amalgam by electrolysis of an aqueous lithium chloride solution which is procured at 8 from a fractionating column 6. The lithium chloride containing amine solution withdrawn from the top of the column 1, is introduced into boiling water in the bottom of the column 6 and anhydrous amine is withdrawn at 7 at the upper end of the column and recycled to dilute the cadmium chloride solution, whilst the aqueous salt solution is cycled to the electrolysis apparatus. Lithium amalgam having an enriched Li6 content is withdrawn at a point 11 and lithium chloride having an enriched Li7 content is withdrawn at a point 12.  A quantity of lithium equal to the total quantity withdrawn is supplied to a point in the column 1 where the concentration of enriched Li6 is approximately equal to the concentration of unenriched lithium.
