Title: Radiation ratemeter
IPC: H01J47/04
Filed: 1961-03-22
Abstract: 950,560. Radiation ratemeters. BENDIX CORPORATION. March 22, 1961 [March 30, 1960], No. 26564/63. Divided out of 950, 559. Heading G1Q. A radiation ratemeter has two electrometer elements placed under potentials of common polarity from a permanent energy source and positioned in an ionization chamber so that their relative deflection is a measure of the rate of ionization of the air volume in the chamber. The energy source is arranged to provide a current of low intensity, incapable of instantaneously compensating for the ionization current at the lowest radiation intensity to be measured. Fig. 1 shows a ratemeter in which the energy source is a layer of α emitting Polonium 178 mounted on a base 176 supplying positive charge via collector 170 to electrometer elements 172 and 174 of equal resistance. The fibre 174 is deflected away from the fixed element 172 by e. s. repulsion and the potential applied to these elements is limited by leakage resistor 180. On ionization of the air within the ionization chamber, defined by concave insert 164, flow of negative ions to elements 172 and 174 reduces their mutual repulsion and the change in deflection of fibre 174 gives a measure of the radiation intensity. The movement of fibre 174 is viewed through a microscope against a log scale calibrated to read in rontgens hour. On removal of the meter from the radiation field, fibre 174 returns to its position of maximum deflection. An alternative embodiment using as an energy source a battery of the solid ion type is described.

Title: Improvements in or relating to the control of electrolytic cells
Inventor: SZECHTMAN JOSHUA
IPC: C25B9/14
Filed: 1962-07-13
Abstract: In a liquid cathode electrolytic cell, the anode to cathode gap is adjusted by altering the level of the liquid cathode, through a vertical draw-off tube which can be raised or lowered.  The appartus may be used to prepare sodium either from brine with a mercury cathode, or from fused NaCl using molten lead.  A horizontally hermetically sealed cell is fed with the electrolyte and the liquid cathode individually at one end and they pass into the electrolysis chamber 17 the floor 15 of which slopes slightly towards the discharge end.  A series of anodes are fixed to the cover 30 by stems 52, and an outlet is provided for the generated chlorine.  Two downwardly <PICT:1013121/C6-C7/1> depending walls 88, 89 dipping into the liquid cathode, form intermediate and end walls, the former having an opening 94 through which floating dross is removed.  The outlet for the liquid cathode from well 90 consists of sleeve 102 rotatably mounted by an external screw in an outer cylinder 104 secured to the cell bottom.  The sleeve 102 has a conical seat 105 to receive the lower end of an upper sleeve 106 having overflow apertures 132, the height of which is controlled by raising or lowering sleeve member 102, on which sleeve 106 rests, by the screw handle 127 the shaft of which is secured to the bottom sleeve 102 through a cross-bar 122.  The position of the level may be calibrated on a set screw 130, and the anode/liquid cathode gap may be maintained constant automatically, by a voltage relay and motor, the voltage rising as the gap increases by wearing away of the anodes e.g. an increase in the gap from I/4 -\ba5/16 inch gives a voltage rise from 4.1-4.2 V.  Dross is removed from the cell by raising the sleeve 106 having a magnetic device 148 which may be energized by an upper fixed magnetic coil 145, and then by a lower coil 146, restoring the sleeve to its lower position.  In the upper position both electrolyte and liquid cathode dross are removed. In similar manner, the mercury level may be raised to clean the surface of the anodes, the current being switched off. Specifications 1,007,778 and 1,013,121 are referred to.

Filed: 1924-11-12
Abstract: 245,553. Johnson, J. Y., (Badische Anilin & Soda Fabrik). Nov. 12, 1924. Pumping machines; multistage.-In carrying out reactions between gases and vapours under pressures exceeding 100 atmospheres, the reactants are circulated by means of a multistage centrifugal pump driven by an electromotor, both of which are disposed within a highpressure vessel forming part of the reaction circuit. If the reaction product is injurious to the motor, the latter is so arranged as to be surrounded only by the indifferent reaction gases. An apparatus for circulating the gases in the synthesis of ammonia consists of a high-pressure vessel A containing a multistage centrifugal pump E and an electromotor D for driving it, the pump being mounted on a partition G. The circulating gases enter the vessel at K and leave at L, and to ensure that no ammonia comes into contact with the motor, a partition F is arranged between it and the pump, and an inlet M is provided for the introduction of fresh nitrogen and hydrogen. The partition F and inlet M may be dispensed with when no injurious product is present in the gases entering at K.
