Title: Presses
IPC: B27N3/16
Filed: 1966-03-16
Abstract: 1,124,411. Moulding chip-board. NIEDERRHEINISCHE MASCHINENFABRIK BECKER & VAN HULLEN. 16 March, 1966 [26 March, 1965], No. 11498/66. Heading B5A. In a chip-board press in which a mat 3 is intermittently advanced between heated press platens 1 and 2 on a belt 4, the slack in the belt, caused by the thermal expansion thereof in the region of the press, ist aken up, after opening the press and before movement of the belt, by a tensioning device 6. Tearing of the board at the junction between its pressed and unpressed regions is thus obviated. In operation, after a section of the mat has been pressed and the upper platen raised, roller 7c of the tensioning device is pivoted by hydraulic ram 10 to take up the slack in the belt, movement of the pressed board 3a during this time being prevented by an hydraulically activated gripping means 12. Roller 16 is then lowered to press the board firmly against the belt and the gripping means released so that when the belt is driven the board is forwarded with the belt and a fresh region of impressed mat drawn into the press. In an alternative embodiment (see Fig. 2, not shown) the gripping means is movable in a direction opposite to that of the belt to allow for shrinkage of the pressed board.

Filed: 1971-04-27
Abstract: 1325225 Shutter mechanisms HATTORI TOKEITEN K K 27 April 1971 [1 May 1970] 11572/71 Heading G2A An electric shutter mechanism includes a shutter 26, 26' opened and closed by a driving member 3 as controlled by a control member 2, the control and driving members being arranged for movement about a common axis 1, an electromagnet 9, and at least two springs 6, 11 arranged so that in operation the driving member moves in the same direction to open and to close the shutter and the control member is biased towards the electromagnet when the shutter is cocked (as shown). Upon shutter release, lever 15 is moved from engagement with driving member 3 which rotates counter-clockwise under the action of spring 11. An upstanding part 12 thereon engages a turn up 20 on opening lever 18, which, together with sector lever 22 rotates counter-clockwise about pivot 19 to open the shutter. Control member 2 is held by energization of electromagnet 9 and carries an arm 8 disposed in the locus of movement of a pin 10 carried on the driving member 3 so as to hold the driving member in the shutter open position. At the end of the exposure interval, the electromagnet is deenergized and the driving member and the control member rotate counter-clockwise together under the action of spring 6, a closing action driving projection 13 engaging a pin 23 on sector lever 22 to rotate the lever clockwise to close the shutter. During the opening action of the shutter, lever 22 operates a changeover switch 31, 32, 33. During high speed exposures, the electromagnet may be de-energized before pin 10 has engaged arm 8, in which case driving member 3 rotates continuously to open and then close the shutter. The spring constant of spring 11 is preferably chosen to be larger than the spring constant of spring 6 so that armature 4 carried on control member 2 is urged towards the electromagnet. Alternatively, a pin (41) Fig.5 (not shown) mounted on driving member 3 is provided to engage arm 8 of control member 2 to urge the armature to the electromagnet.

Patent GB-801742-A (GB)
Title: Solvent extraction of neptunium
IPC: C01G56/00
Filed: 1955-04-25
Abstract: Neptunium is extracted from a strongly acidic aqueous nitric acid solution, which also contains plutonium and/or fission products, by treating the solution, in which the plutonium is in the trivalent state and the neptunium is in the tetravalent or higher state, with tributyl phosphate dissolved in an inert substantially water-immiscible organic solvent.  If the plutonium is in the tetravalent or higher state, the original aqueous solution is treated with a reducing agent, e.g. ferous sulphamate, hydroxylamine, or sulphurous acid.  The neptunium is preferentially extracted into the organic solvent phase which is scrubbed with 4N nitric acid solution containing a reducing agent; neptunium is returned to aqueous phase by washing with water.  The inert organic solvent may be white spirit, benzene, carbon tetrachloride, or kerosene, tributyl phosphate being present in a proportion of 20-30 per cent by volume. When uranium is present, e.g. in solutions obtained by dissolving neutron-irradiated uranium, it may be removed (a) by washing the organic phase with 0.6N nitric acid when uranium remains in the organic phase and neptunium passes into the aqueous phase; or (b) by extracting uranium from the original solution with hexone, using zinc nitrate as salting-out agent.  Examples describe the separation of neptunium (a) from solutions containing also uranium, plutonium, americium, curium, and fission products; and (b) from an aqueous solution obtained by extracting irradiated uranium solution according to the process of Specification 801,743 and treating the organic extract with dilute nitric acid containing a reducing agent.

Title: Improvements in or relating to phase modulated carrier wave receivers
IPC: H03D3/00
Filed: 1944-06-24
Abstract: 587,001. Phase and frequency modulation ; valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 24, 1944, No. 12039. Convention date, June 24, 1943. [Class 40 (v)] In a phase-modulated wave receiver wherein a frequency-modulation detector is used with audio -frequency correction, at least two audiofrequency compensating networks are used, one for de-emphasising the higher modulation frequency response and another for emphasising the lower modulation frequency response which is not affected by the first-mentioned network, so as to give a net response inversely proportional to frequency. The loss of gain at the lowest useful modulation frequencies inherent with single compensating networks is thereby avoided. The P.M. wave is passed through a F.M. detector 1, preceded, if desired, by a limiter stage, to the first compensating network R1, C1, which de-emphasises the higher modulation frequency response. The network output across condenser C1 is applied to an audioamplifier 2<1>, the series resistor-condenser network R2-C2, in the anode circuit of which constitutes the second compensation network for the lower modulation frequencies. The output of tube 2<1> is passed through a flat frequency response-audio-amplifier comprising, e.g. resistance-capacity coupled tubes 4, 10, 14, the output tube being of the cathode follower type and providing a negative feedback voltage to tube 4. over line 8. A H.F. equalizing coil 13. is included in the plate load circuit of tube 10. In a modification, Fig. 4 (not shown), the two compensation networks are duplicated for push-pull operation of two cascade-connected pairs of tubes replacing the amplifier 2<1> of Fig. 2. The Specification gives illustrative values. for the compensation network constants.
