Title: Electromagnetic disturbance neutralization radiation detector
Inventor: GRIPENTOG W G
IPC: H01J47/02
Filed: 1972-08-16
Abstract: 1364198 Radiation detector circuits UNITED STATES ATOMIC ENERGY COMMISSION 16 Aug 1972 [1 Sept 1971] 38125/72 Heading G1A In a radiation detector comprising an ion chamber vacuum-tube electrometer combination wherein the control grid of the electrometer tube is normally connected only to one of the electrodes of the ion chamber, a system is provided for automatically draining extraneous charge from the control grid in response to a cessation of anode current in the electrometer tube. The circuit shows a combination of an ion chamber C comprising a positive electrode 10 and a negative collector electrode 12 which is directly connected to the control grid 14 of a triode strapped tetrode electrometer tube V and a relay K arranged so that when energized the control grid 14 is connected to the cathode circuit, this combination being known the relay being used for calibration purposes. Electromagnetic radiation of long wavelength may inductively couple into the output lines of the detector and be rectified by the electrometer tube V depositing a negative charge on the control grid 14 cutting off tube V and leaking away only very slowly. To overcome this effect the circuit is arranged so that relay K is energized to discharge the grid 14 in response to a cessation of anode current. The anode of tube V is held at virtual ground by means of an op amp 18 having a feedback loop resistor R2. A positive supply is also applied over resistor R3 to the inverting input so that the anode current of tube V may be offset at a value corresponding to the average background radiation so that zero output voltage is provided at line 30 relative to line 16. When the radiation level increases tube V passes more current and the output voltage at line 30 rises. If however the tube V is cut-off due to an accumulation of negative charge on its grid 14 the background offset current through resistor R3 drives the output of the op amp 18 negative. A negative output of sufficient amplitude causes comparator 34 to switch driving transistor Q into conduction energizing relay K to drain the charge from the tube grid. When anode current starts to flow the output of the op amp rises and comparator 34 switches back de-energizing relay K to restore the circuit to the normal measuring condition. Switches S are provided to facilitate checking and recalibration of the circuit. After initial calibration the switches S are operated first to one position and then to the other and resistors R6 and R7 are adjusted to give convenient output readings which are noted, the relay K being energized during this adjustment. Subsequent checking can be achieved by operation of the switches, adjustments being made to the resistors R2 and R3 to return the output to the noted values. It is mentioned that the relay can be directly energized from the op amp output in response to a negative excursion by replacing the comparator and transistor Q by an appropriately poled diode.

IPC: C10G49/12
Filed: 1959-11-20
Abstract: <PICT:0963974/C1/1> <PICT:0963974/C1/2> An apparatus for mixing two liquid faces of different density and subsequently separating them comprises a container in which the flow from the rotor is arranged to change from a tangential to a radial flow.  The rotor 1 is constituted by a flat circular plate 2 having eight depending vanes 3 and the diffuser 5 is constituted by an annular plate 6 having eight depending vanes 7 disposed regularly and radially of the rotor axis. The two phases flow to the centre of the rotor through an inlet pipe 8 in the direction shown by the one of the lower arrows and the outlet flow is shown by the upper arrows.  Each arrangement of the rotor can constitute a stage in a multistage stage can be generally used with 10 to 16 stages.ALSO:<PICT:0963974/C4-C5/1> Crude soap is heated to 80-90 DEG  C. and pumped by means of pump 40 to the washing unit at a predetermined rate in an even flow. The anhydrous soap content of the crude soap should not exceed 57%; it may be adjusted by mixing in a small amount of spent lye from pipe 41. The brine, of a constant predetermined composition, after heating to about 90 DEG C. is fed through inlet pipe 42.  The flow of the brine is controlled by a valve 43 responsive to the interfacial float 44.  The mixture of crude soap and lye enters the unit through the inlet distributer 45. The soap separates from the lye and floats upwards under the conical baffles 28, 29, until it reaches the rotor 1.  The lye settles to the bottom and is partly pumped round the circulation system again, partly taken out of the system as spent lye through pipe 41.  The rotor 1, being a pump wheel, circulates the lye in the lowest section continuously, the lye flowing to it through the narrow space between the conical baffles.  The soap from the bottom of the tank and the lye in the bottom section mix in the rotor of that section and the resulting intimate mixture of lye and soap is thrown out of the rotor against the diffuser and flows then radially in a quiet fashion, into the settling space of the bottom section.  The soap floats upwards and passes into the rotor of the next upper section.  The lye flows downwards and then upwards between the conical baffles, partly into the rotor of the bottom section again, where it is mixed with fresh soap, and partly into the bottom of the tank, to replace the outgoing glycerine lye, which is withdrawn from the lye circulation system. All the intermediate sections of the washing unit are alike.  The soap is settled in the top section.  The settled soap 48 runs off over a weir 46 and pipe 47.  The sodium chloride may be wholly or partially replaced by other salting out electrolytes such as sodium hydroxide and the temperature should not be allowed to drop below 85 DEG  C.  A modified arrangement for the neutralizing of a glycerine lye containing up to 2% of a free alkali with fat containing up to 20% of free acids is described in Fig. 13 (not shown).
