Title: Improvements in and relating to differential mechanism for cash registers
IPC: G06C7/10
Filed: 1922-10-26
Abstract: 210,164. Haddan, A. J. H., (National Cash Register Co.). Oct. 26, 1922. Differential mechanism.-A latch carried by the differential member co-operates with a constant excursion member and is controlled by the differentially adjustable setting levers whereby the latch is broken when the member has been driven to the desired extent. Setting mechanism. The setting levers 130 move in fixed guide frames 140 a plate on which is notched for engagement by a spring pin on the setting lever. When a shaft 88 is rocked counterclockwise, Fig. 2, on the operation of the machine, the forked member 147 is rocked by a pin on an arm 146 and a locking plate 148 is raised and a co-operating plate 151 forced inwardly to bring a depression 150 over a stud 159 on the lever. The lever 130 is returned at the end of the operation by engagement of a curved part 172 on a pivoted part 169 by a pin 170 on a disc 171 on the shaft 112, the part 169 rooking and engaging an extension of a pivoted segment 165 in gear with a segment 164 on the lever. Construction and operation of different units. Each differential unit comprising plates 228 and 229 between which are secured the toothed segments 227 turns about the fixed rod 139 as axis. A constant excursion member comprising a segment 226 is driven by cams 213, 214 on the main shaft 112 through the medium of a Y-shaped lever 217 and link 225. A latch 232 is carried between the plates 228, 229 by means of arms pivoted to the latter, and a foot 238 on the latch is engaged by a shoulder 239 on the segment 226. The latch and members 228, 229 are thus rotated with the segment 226 until an arm 241 strikes a lug 242 on the setting lever, whereupon the arms supporting the latch are rocked to move the latch out of engagement with the shoulder 239, the foot 238 then riding on the outer periphery of the segment and a forward end engaging one of the notches 244. An arm in one with a plate 246 loose on the axis 139 lies in the plane of the zero stop 250, and when the setting lever is moved the arm strikes the stop 250 and rocks the supporting arms to break the latch. Displacing zero pawl when setting lever is not moved. Each setting lever carries a pin 260 cooperating with a cam surface 261 of a curved plate 262 pivoted to one arm of a bell-crank 263. The plate 262 carries a pin 264 projecting through a slot in one arm of a two-armed lever 265 pivoted on a curved plate 266 supported at its upper end by the other arm of the bell-crank 263 and at its lower end by an arm 267 fast on a sleeve 268 on a fixed stud 140. Fast on the sleeve is an arm 269 having a pin and slot connection with the end of the lever 265. When the lever 130 is moved the parts 262. 265, 268, 267 are rocked and a tail 270 engages a pin on the zero stop to displace it. The differential members are restored to normal by the segment 226 engaging a pin 256 carried by the plates 228, 229. The differential mechanism for the clerk's bank of keys is similar, the parts 227, 228, 229 being replaced by an arm.

Title: Plutonium concentration and decontamination method
IPC: C01G56/00
Filed: 1956-10-01
Abstract: 881,151. Plutonium separation. UNITED STATES ATOMIC ENERGY COMMISSION. Oct. 1, 1956 [Oct. 28, 1955], No. 29927/56. Class 39(4) An aqueous mineral acid solution containing a small amount of plutonium is concentrated and decontaminated by adjusting the acid concentration to a fractionally normal value and converting the plutonium to the Pu<SP>¸3</SP> oxidation state, then contacting the solution with a cation exchange material which absorbs plutonium, and subsequently eluting the plutonium with an aqueous nitric acid solution of concentration at least 4 molar, while maintaining the plutonium in the Pu<SP>¸3</SP> state. When uranium is also absorbed on the cation exchanger, it may be eluted before the plutonium, preferably using a dilute aqueous sulphuric acid; dilute nitric acid, hydrochloric acid, or hydrogen fluoride, or solutions of citric or acetic acid, may also be used. Reduction of plutonium in the initial solution is effected with hydroxylamine sulphate, hydrazine, ferrous sulphamate, sulphamic acid, or low molecular weight 'aliphatic ketones or aldehydes, e.g. formaldehyde. Suitable cation exchange substances are natural zeolites and glauconites, synthetic gels prepared from sodium silicate and aluminium salts, and sulphonated carbonaceous substances as described in U.S.A. Specification 2,171,408; especially suitable are polymers containing nuclear sulphonic groups, for example sulphonated phenol-formaldehyde and polystyrene resins as described in U.S.A. Specifications 2,204,539 and 2,366,007. Elution is preferably carried out by passing the element through the bed in the opposite direction to the feed. Fission products may be removed from the ion exchange bed by washing with oxalic acid or ammonium citrate solution. Plutonium may be precipitated from the product solution as plutonium peroxide, which is hydrofluorinated to form plutonium tetrafluoride and then reduced to metal with an alkaline earth metal.

Abstract: 1,221,463. Photo-electric atomic absorption spectrometry. INSTRUMENTATION LABORATORY Inc. June 24, 1968 [July 12, 1967], No. 29954/68. Heading G1A. The atomic absorption of a sample introduced into a flame is measured by passing a first beam of radiation from a source through the flame to a first detector and a second beam from the source directly to a second detector, and comparing the logarithms of the outputs of the detectors. Calcium and strontium light from squarewave energized hollow cathode lamps 12, 14, Fig. 1, respectively is focused into the flame 10 by a quartz lens 44 and the emergent light is split at 49. The intensity of the strontium light before and after passing through the flame is measured by photo-diodes 26 and 24 provided with filters 32, 30. The intensity of the calcium light is measured before passing through the flame by a photo-diode 28 and filter 34 and after passing through the flame by a grating mono-chromator 22 and photo-multiplier 20. The pulsating outputs of detectors 20 and 28 Fig. 6 are synchronously demodulated and applied to logarithmic converters 206. The output of one of the converters is inverted and added to the output of the other to give an output proportional to the logarithm of the ratio of incident to emergent light which, by Beer's Law, is approximately proportional to calcium concentration. First order compensation for nonlinearity in Beer's Law is provided by mixing a fraction of the incident intensity with the emergent intensity at 220. The detectors 24, 26 are connected in a similar circuit and the outputs of the two circuits may be combined to determine the relative amounts of calcium and strontium e.g. to determine calcium using strontium as an internal standard. Burner construction and control. A mixing chamber 82, Fig. 4, is supplied with C 2 H 2  fuel through a pipe 190 and air or N 2 O as oxidant through 192. The mixture, together with the aspirated sample at 172 is burned at a nozzle 80. The supply of fuel and oxidant is controlled by circular control orifices in the supply pipes. Fuel supply is cut off if the burner is not properly positioned or the flame is not detected within 12 seconds of ignition.
