Title: Improvements in precision timing apparatus including an oscillating member subjectedto the action of resilient return means
IPC: G04C3/06
Filed: 1954-07-23
Abstract: 780,262. Electric clocks. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES O.N.E. R.A. July 23, 1954 [ July 31, 1953], No. 21644/54. Class 139 [Also in Groups XIX and XXXV] In a timing apparatus having a magnetically maintained balance the periodically closed contacts of the maintaining circuit are closed when the circuit is broken so that the balance oscillation is self-starting. The balance 1, Fig. 1, is mounted on a staff 2 rotatable in bearings 3, 4 within an insulated casing 5. Fixed to the balance 1 is a soft iron plate 6 having symmetrically disposed pole pieces 7a, 7b, 8a, 8b, Fig. 2, which co-operate in the usual manner with pole pieces 9, 10 of the armature 11 of an electromagnet 11, 12, 13, Fig. 1. The balance return means consists of two diametrically opposed springs 20a, 20b, the inner ends of which are fixed to pins 21a, 21b respectively, located between the balance 1 and a plate 18 and the outer ends of which are fixed to adjustable supports. The plate 18 also supports the contact pin 33 which co-operates with the contact means 17 to periodically energize the electromagnet 11, 12, 13 and so magnetically impulse the balance. The contact means 17 comprises a finger 31 freely pivoted on a pin 32 and normally retained in the position' shown in Fig. 2 by two springs 34a, 34b. The arrangement is such that if the main switch of the maintaining circuit is opened the pin 33 will come to rest against one or other face of the finger 31 with the balance out of its mid position so that upon closure of the main switch the balance is immediately impulsed and starts oscillating. The finger 31 may be modified as shown in any of Figs. 5-7 and urged to its normal position by one or two springs. In the diagrammatic arrangement shown in Fig. 8 the balance arrangement, abcve described, includes a contact 44 which as the balance oscillates meets contacts 43a, 43b 'to send impulses to the coil 12<SP>1</SP> of a frequency divider the electromagnet 11<SP>1</SP>, 12', 13<SP>1</SP> of which oscillates a plate 6<SP>1</SP> carrying a pawl 51 which steps-on a ratchet 49 prevented from rotating backwards by a pawl 52. The ratchet spindle carries a contact finger 54 which co-operates with one or more stud contacts 56 to send impulses to the coil 60 of an electromagnet 58, 59, 60 of an optical signal transmitter including an oscillating plate 67 which carries a mirror 73 which reflects a beam of light which may sensitize a recording band.

In the Burroughs machine shown in Figs. 1 and 2, a stationary shoot 30 for receiving a postcard 35 is arranged in front of the platen 16 and consists of flared plates 33, 34 secured to supports 31, 32 on the back panel 25. The plates have openings 36 for permitting the types 11 to impress the postcard, and a ledger sheet 71 carried by the platen. The lower part of the postcard passes between the back panel and a flanged plate 37 secured thereto. The bottom edge of the postcard engages a lug 43 on a line-spacing slide 40 geared to a ratchet-wheel 49 co-operating with a pawl 50 carried by the slide 27 that controls the tabulating movements of the platen-carriage 15. The line-spacing slide co-operates also with a detent 54a. At each operation, one of a series of entries such as the items of a gas bill is typed on the postcard and ledger sheet, the postcard is line-spaced, and the platen-carriage receives a tabulating movement, successive items being typed in column form on the postcard and in a horizontal line on the ledger sheet. When the platen-carriage makes its final movement, a cam 60 on the platen-carriage releases the detent 54a, and a spring 45 returns the line-spacing slide. The gross and nett amounts may be repeated on a stub part of the postcard, repeat typing on the ledger sheet being prevented by employing a carbon sheet that does not cover the right-hand column of the ledger sheet.

Abstract: 1355450 Copying by scanning INFORMATION INTERNATIONAL Inc 11 May 1972 [17 May 1971] 22028/72 Heading H4F The video signal derived by optically scanning an original is converted into binary signals which represent the tones of segments of the original, and these signals are supplied to a memory 52 which contains the correct coded binary signals to reproduce a halftone character dot of correct size on a cathode-ray tube 54 for each of 64 possible input binary signals, a received binary input signal addressing a primary memory 92 which provides the address of the corresponding coded binary signal in a secondary memory 94. Separate memories may be provided for alphanumeric symbols which are also to be displayed as part of a composite picture. The coded binary signals include signals indicative of the horizontal distance from the start of the character space to the start of the character dot which is fed to adder 106; the horizontal distance from the start of the dot to the end of the character space, which is fed to register 108 to be supplied to adder 106 at the beginning of the following character; the number of vertical line scans of tube 54 for the dot which is fed to counter 120, which is counted down by a count of one at the end of each vertical scan; the vertical distance from the bottom of the character space to the bottom of the dot, which is fed to register 138; and information regarding which parts of each vertical scan (which means are vertically upwards) the beam of tube 54 is to be unblanked, which is fed to register 124. The scanning beam is correctly positioned at the beginning of each character by the outputs of accumulator 110 and register 138 fed to control circuits 116. Sawtooth generator 128 is activated when the information for one vertical scan is contained in register 124 by the output of a bit detector 126 detecting a "1" in the least significant (2‹) position of a received word and the tube 54 is unblanked when bit detector 136 detects a "1" in the 2<SP>1</SP> position in a word. Flyback of the beam takes place at the completion of the unblanked portion of each vertical scan by detection by detector 136 of the "1" in the 2‹ position. At the end of a character scan counter 120 has counted to zero, which is detected at 122 to provide a signal to read the following character from a magnetic tape 40 on which the input binary signals are recorded. The resulting character dots on adjacent horizontal lines are spaced apart horizontally by half a character space (Fig. 4, not shown).

Title: Separation of uranium, plutonium and fission products
IPC: G21C19/46
Filed: 1949-08-24
Abstract: In the recovery of uranium from an aqueous nitrate solution containing also plutonium an fission products, e.g. a solution of neutron-irradiated uranium, the solution is saturated with a nitrate, the plutonium is reduced to the tervalent state, and uranium is extracted from the substantially neutral solution with a water-immiscible organic solvent.  The nitrate solution may be neutralized by adding ammonia, calcium oxide, or zinc oxide. Ammonium, aluminium and zinc nitrates are suitable for saturating the solution.  Reduction of the plutonium is effected with hydroxylamine or its hydrochloride or nitrate, hydroquinone or hydrazine.  Suitable organic solvents are dibutoxy dibutyl ether, methylisobutyl ketone, ethylene glycol dibutyl ether and diethyl ether.  To recover plutonium, the remaining aqueous phase is acidified with nitric acid, the plutonium oxidized with ammonium, potassium, or sodium chromate or dichromate, potassium permanganate, or ammonium cerium nitrate, and the plutonium extracted by another treatment with the organic solvent; the steps of acidification and oxidation may take place in either order. Uranium and plutonium are returned to the aqueous phase by washing the organic extracts with water or slightly acidified water.
