T., The Chimes, Acacia Avenue, Eastcote, Ruislip, and KENT, E. C., 22, Dorset Avenue, Norwood Green, Southall, both in Middlesex. March 13, 1935, No. 7837. [Class 80 (i)] [See also Group XVIII] A reduction gear comprises an externally-toothed wheel 25, which has a comparatively large number of teeth, and engages a projection, or a set of widely - spaced projections such as the pins 27 on a spider 26, which is caused to gyrate by an eccentric 15 so that each of the pins in succession moves inwardly to rotate the wheel 25. The spider may have not more than seven pins. Rotation of the spider may be prevented by one of the pins 27 engaging a fixed guiding slot 30 ; or one of its pins may engage a fixed gear wheel having a different number of teeth from the driven wheel. A light frictional brake may be applied to prevent movement when the driving pin or pins is or are out of mesh. The axis of rotation of the eccentric may be eccentric to the axis of the driven wheel. As applied to an electric clock the gearing comprises two trains supported on a common spindle and giving a reduction of 1: 7200 from the synchronous motor to drive the minute hand. The invention may also be applied to recording mechanism, registering mechanism, and advertising devices.

Title: Circuit for linearizing the response of an electron capture detector
IPC: H03K7/06
Filed: 1977-02-24
Abstract: 1521244 Electron capture detector circuits VARIAN ASSOCIATES Inc 24 Feb 1977  [26 Feb 1976] 07935/77 Heading G1N In an electron capture detector of the type in which the average cell 12 current is maintained constant by varying the frequency of a train of pulses applied thereto, the pulses are produced by integrating 35 the output of electrometer amplifier 22, comparing the output from the integrator 35 with a reference voltage at 44, and applying the triggering pulses 54 so produced to pulse generator 56. The cell 12 output current is subtracted from reference current I REF  before being applied via amplifier 22 to integrator 35 and whenever the integrator output, the slope of which depends on the magnitude of the electrometer output, equals the magnitude of the fixed reference voltage VREF comparator 44 provides a signal 54 on line 52 to transistor switch 38 to reset the integrator 35 whereby a sawtooth waveform 40 is obtained. The negative going pulses 60 from generator 56 are fed to cathode 14 and to pulse averager 64. If the output from a chromatograph coupled to cell 12 includes any electronegative material the cell current decreases and the slope of sawtooth waveform increases whereby the frequency of the negative pulses 60 increases and the output from frequency-to-voltage converter 64 indicates this. At the same time the electron current in cell 12 is increased by the feedback on line 62 to restore stability.

Title: Improvements in or relating to vibratory apparatus particularly for consolidating soil
IPC: E02D3/074
Filed: 1962-03-01
Abstract: 932,782. Soil consolidation apparatus. E. ROSENTHAL. March 1, 1962, No. 8037/62. Class 107. [Also in Group XXIV] Vibratory apparatus, particularly for consolidating soil comprises a base-plate 1, a driveshaft 2 mounted in bearings 3 and driven by, e.g., a V-belt pulley (not shown), at least one frame 6 journalled on the shaft 2 for limited angular movement in a plane parallel to the plate 1 and at least one auxiliary shaft 14 mounted on the frame parallel to the shaft 2 and rotatable therewith but in the opposite direction through meshing gears 16. Out-ofbalance weights 17, 18 fixed to the shafts are of such mass and so mounted that the forces generated by rotation of the weights counteract each other in a direction parallel to a line 15 joining the axes of the shafts 2 and 14 but add in a direction perpendicular to that line. The angular adjustment of the frame 6 is varied by engagement of a rotatable worm 11 with a worm-wheel 10 or by piston-and-cylinder means 13. With the line 15 parallel to the plate 1 rotation of the shaft 2 causes vibration of the apparatus only in the direction perpendicular to the plate 1. If both of two frames 6 are adjusted in the direction of the arrows 8 or 9, rotation of the shaft 2 gives rise primarily to forces acting in a direction perpendicular to the plate 1 but also to forces having a component parallel to the plate which tend to move the apparatus to the right or left, respectively, as shown. If the frames are angularly adjusted in opposite directions the apparatus is caused to rotate. In an alternative embodiment (not shown) which comprises two frames 6, one auxiliary shaft 14 with its associated weight 17 is omitted from each frame but at opposite sides of the apparatus and the weights 18 made equal to the weights 17.

Title: Extraction of alkali metals from their amalgams
IPC: C22C3/00
Filed: 1952-04-01
Abstract: In a process for the extraction of alkali metals from their amalgams, a dilute amalgam, prepared by electrolysis of an aqueous solution of an alkali metal salt in a cell provided with a mercury cathode, is concentrated until an alkali metal concentration of more than 10 per cent (e.g. 40-60 per cent) is obtained, a substantial part of the alkali metal in the amalgam is dissolved in a solvent, the alkali metal is separated from the solvent or used in solution for the preparation of derivatives (e.g. peroxides or amides) and the exhausted amalgam is concentrated as by recirculation <PICT:0720498/III/1> through the apparatus.  The solvent may be ammonia, ethylene diamine, methylamine or hydroxides of alkali metals, other solvents inert to alkali metals, a mixture of solvents, or a mixture of solvents and an inert non-solvent.  The amalgam may be in a hot or cold, solid or liquid state, the separation taking place under pressures and /or temperatures appropriate to this state. In the case of the extraction of Na, fused NaOH (to which Na2CO3, KOH, NaBr or NaI may be added to lower the melting point) is used as a solvent, and the Na may be precipitated by further heating.  In one example, using NH3 as a solvent, hot liquid amalgam from 7 containing 0.4 per cent. Na by weight is mixed with the exhausted amalgam (26 per cent Na) from the extraction column 3 and passed to a distillation column 1 where the Na content is raised to 50 per cent, the temperature not exceeding 550 DEG C.  The concentrated amalgam is cooled to 70 DEG C in a heat exchanger 2 and fed to the extraction column 3 in counter-current to liquid NH3, from a condenser 5, at a pressure of 35 Kg/cm2 and a temperature of 70 DEG C.  The outgoing solution is fed to an evaporator 4 where it is submitted to a pressure of 62 Kg/cm2, liquid Na at 100 DEG C is separated, and the NH3 vapours are condensed in a condenser 5.
