Title: Improvements in method and apparatus for measuring radiation
IPC: G01T1/04
Filed: 1964-08-19
Abstract: 1,061,535. Detecting neutrons. GENERAL ELECTRIC CO. Aug. 19, 1964 [Sept. 11, 1963], No. 33862/64. Heading G6P. [Also in Divisions G1 and H5] A dosimeter for personnel or reactor applications comprises a body of material which is permeable to damage track producing fission fragments and either is provided with a strip of fissile material adjacent to it or the material itself contains such a fissile material, which material, on exposure to the radiation being measured, produces fission fragments, substantially all of which produced in an exposure period are subjected to the permeable material to produce damage tracks therein. After exposure, the dose received by the dosimeter is evaluated by a measurement of the porosity of the permeable body after it has been etched to remove the damage track defining material. The dosimeter 17 (Fig. 3, not shown) forms part of a personnel radiation badge, comprising a plastics box (10) (Fig. 1, not shown) in which are contained a strip (20) of fissile material, which may be natural uranium, natural thorium, U238 or U235 and a mica sheet (19) (the permeable body), enclosed in a shield (21) of cadmium, which is open over half the top surface of the strip (20) (Fig. 3, not shown). The dosimeter can detect thermal, or fast neutrons (>1MeV) or high energy γ-rays (>5 MeV). These produce fission fragments in the strip (20) which travel straight through the mica sheet (19). Read-out of the mica sheet consists of first etching the sheet with acid solution, e.g. HF, to remove the material, defining the tracks of the fission fragments, followed by measurement of the porosity of the sheet by means of an optical microscope (counting the pores), by electrical conductivity determination or by gas flow measurements (Fig. 6, not shown). Values are given of the dosimeter response to the various particles for the alternative fissile materials and of the minimum detectable doses and dose rates obtainable. Differentiation between γ's and thermal neutrons is possible by measurements with and without the cadmium shield (21). Other materials which may be used for the track detecting strip (19) are natural or synthetic glasses or plastics, in which latter case, alkali etchant is used. In high radiation level work, e.g. in reactors, the badge may be used with the strip (19) alone, its natural uranium content acting as a source of fission fragments. In this case the dosimeter casing is of metal.

Abstract: 979,229. Cigarette-making machines. AMF-SASIB S.p.A. Aug. 30, 1963 [Aug. 31, 1962], No. 34463/63. Heading A2C. A method for regulating the weight of cigarettes in cigarette-making machines provided with a tobacco-compactor-wheel having a peripheral channel with an air permeable bottom through which suction is applied for compacting the tobacco fed thereto, is characterized by regulating the weight of the cigarettes by varying the cross-sectional area of the channel. The tobacco-compactor-wheel 3 comprises a disc shaped part 303 and a cylindrical flange 403. The part 303 is provided with a hub 103 keyed to a tubular shaft 13 driven by gears 25, 26. An air permeable tobacco carrying band 203 is fastened on the flange 403. The open end of flange 403 is closed by a fixed disc 14 and suction is applied to the tobacco carrying portion of the band 203 through opening 15. An adjustable revolving brush 9 removes surplus tobacco at a predetermined height. A ring or side wall 22 is fastened to the open end of the wheel flange 403 while an opposing ring or side wall 23 constitutes a flange of a disc 24 which revolves with the wheel 3 but is axially shiftable thereon. The disc 24 is provided with a hub 124 which is slidably mounted axially on the shaft 13 and coupled to the hub 103 of the wheel 3 so as to revolve therewith. A knob 27 is screwed on the hub 124 and is coupled to shaft 13 so as to rotate therewith but be axially movable thereon so that the unit comprising the ring 23, disc 24, hub 124 and knob 27 is coupled to, but axially shiftable on, the shaft 13. The knob 27 is fastened to a rod 29 slidably mounted within the shaft 13 and joined to a sleeve 30 by a screw threaded coupling. The sleeve 30 is rotatably mounted in a bell 31 keyed to shaft 13 and is coupled to the shaft 33 of a reversible electric motor 34 the stator 134 of which is fastened to the bell 31. The body of the motor thus revolves with the shaft 13. The motor is controlled by a cigarette weight checking device so that if the cigarettes produced are not within a predetermined weight tolerance, the sleeve 30 revolves relative to the bell 31 to screw inwardly or outwardly the rod 29 thus moving the ring 23 to alter the width of the groove in the wheel 3 and correct the weight of the cigarettes produced. A collar 36 is slidably mounted on the hub of the bell 31 and is connected to the sleeve 30 by a screw threaded coupling 136. Relative movement between the sleeve 30 and bell 31 thus effects axial movement of the collar 36 on the hub of the bell 31. The collar 36 is provided with a groove connected to a pointer 37, pivoted at 237, which co-operates with a scale 38.

IPC: G06G7/24
Filed: 1974-08-07
Abstract: 1472206 Exponential junction generators SONY CORP 7 Aug 1974 [10 Aug 1973 (2)] 34826/74 Heading G4G A temperature-compensated exponential amplifier comprises two current-paths connected to a common source, one of which contains a series of PN junctions, the other a cascade of emitterfollower transistors, the transistor devices in both paths having substantially identical PN- junction characteristics whereby the two paths afford mutual temperature compensation. In the amplifier of Fig. 5 the exponent is greater than unity (I n =I 0 <SP>n</SP>). A source 21 of constant current I 0  is connected to the common input terminal 16 of a series 12 of n PN junctions and a cascade 17 of (n - 1) emitter-followers each of which has a respective constant-current source connected between emitter and earth. The emitter of the last member of the cascade is connected to the base of a transistor amplifier 14 whose collector current I n  provides the output. Neglecting base currents and designating base-emitter voltage drops by V, constant currents by I, we have: nV BE0 =V BE1 +V BE2 +...V BEn  I 0 #I s .exp.(αV BE0 ) I 1 #I s .exp.(αV BE1 ) I 2 #I s .exp.(αV BE2 ) ..... I n #I s .exp.(αV BEn ) where α=q/kT. The series of current equations may be written in logarithmic form and substituted into the voltage equation, to give: n/αlog(I 0 /I s )= l/αlog(I 1 /I s )+ ... l/αlog(I n /I s ) hence: I n =I 0 <SP>n</SP>/{I 1 .I 2  ... I (n-1) } The currents I 1 , I 2 , ... I (n-1)  are constant, hence the amplification is exponential with n>1. Since α cancels out of the last equation, the amplification is independent of temperature. Fig. 5 shows an exponential amplifier for n<1 (I n =I 0 <SP>1</SP>/<SP>n</SP>). In this case, a constant-current source 21 is connected to the common input terminal 27 of a cascade 29 of (n - 1) emitterfollowers and the base of a transistor amplifier 22 whose collector current I n  provides the output. The emitter of transistor 22 is connected to a series 23 of (n - 1) PN-junctions, and the emitter of the last emitter-follower in the cascade is connected to the base of a transistor 30 whose collector is connected to the current source 21. The same mode of analysis is applied to this circuit to show that temperature compensation is achieved. The Specification also describes two simpler circuits (Figs. 2, 4, not shown) which yield amplification characteristics I n =I 0 <SP>2</SP> and I n  = I 0 <SP>1</SP>/<SP>2</SP>. The circuits may be used for emphasis and de-emphasis in a video tape-recording system.
