Filed: 1934-12-03
Abstract: 448,243. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd., 9, kingsway, London.-(Assignees of Mergenthaler Setzmaschinen - Fabrik Ges.; 25, Chausseestrasse, Berlin) Dec. 3, 1934, Nos. 34704, 34705, and 34706. Convention dates, Dec. 22, 1933, May 18, 1934, and July 6, 1934. [Class 100 (iii)] Ejecting type - bars; galley-mechanism.-In order to prevent lateral tilting of a thick slug as it is ejected from the mould, the slug is supported during ejection by a resilient surface, preferably in the form of a spring-controlled buffer, which is locked against return movement, so that the slug is released as the ejector retires. A buffer-plate d, covered with felt, indiarubber, &c., is carried by a sleeve f sliding within a casing k. The plate is pushed back by the ejected slug b against the pressure of a spring i, and is latched by means such as a detent m engaging a recess g in the sleeve f. The detent is released, to permit the buffer-plate to return to initial position, by means such as a cam r on the first elevator. Means mav be provided for latching the buffer-plate in different positions to suit slugs of different heights. To prevent tilting of the slug owing to contact with the edge of the mould as it moves downwards, the slug is conducted to the galley y by a curved guide-plate t<2>, which rises behind the lower end of the slug after it is ejected. The guide-plate has an adjustable side wall t<3>, and is carried by a pivoted segment t, which is rocked by a projection v on the buffer-plate. The guide-plate may be movable vertically, and may be operated by the ejector or other part of the machine.

Title: Improvements in or relating to electrolytic separation of isotopes
IPC: B01D59/40
Filed: 1956-11-21
Abstract: 802,555. Electrolytic separation of isotopes. SOC. D'ELECTRO-CHIMIE, D'ELECTROMETALLURGIE ET DES ACIERIES ELECTRIQUES D'UGINE. Nov. 21, 1956 [Nov. 24, 1955], No. 35668/56. Class 41. A method of increasing the proportion of an isotope in a mixture of isotopes comprises applying a sharply increasing voltage across the electrodes of an electrolytic cell containing a liquid electrolyte derived from an isotopic element, one of whose isotopes it is desired to concentrate, and the ions containing said element present in the electrolyte consisting solely of said element, whereby the electrolyte in the immediate vicinity of the electrode towards which the ions consisting solely of said element travel is enriched in one of said isotopic ions, rapidly withdrawing a part or the whole of the ions from the thus enriched electrolyte, reducing the applied voltage to zero, restoring the isotopic composition of the electrolyte in the immediate vicinity of the said electrode to that of the body of the electrolyte and then periodically repeating the operation. As shown in Fig. 1, reservoir 6 is filled with mercury which falls in a stream 4 via rotatable capillary tube 5 into container 1 at the bottom of which it collects to form a layer 9, above which is a layer 7 of carbon tetrachloride. Above the latter layer is a saturated aqueous solution of lithia 8. Anode 3 consists of a ring of iron wire and the stream of mercury 4 acts as the cathode. Upon passing the current, lithium amalgamates with the mercury and the amalgam 9 is periodically run out through tap 2 into the receiver 10 containing a solution of dilute sulphuric acid whereby there is formed a lower layer of mercury 11 and an upper layer of lithium sulphate solution 12. The capillary tube is rotated so that the stream of mercury 4 is continuously moved within the electrolyte. A unidirectional square pulse voltage is applied to the electrodes. The lithium sulphate solution 12 possesses a lower isotope ratio of Lithium 7 to Lithium 6 than that of the initial lithia solution 8. Alternatively the isotopic ions may be deposited as metal on an electrode in the case of metallic ions, or by gas discharge in the case of ions of gaseous elements or by the use of an electrode in the form of a hollow tube with a closed bottom made of porous material, such as compressed and sintered bronze particles, into the interior of which the enriched electrolyte passes during electrolysis and whence it flows to a storage receptacle by means of a suction device. The invention may be carried out using a fused electrolyte. Instead of using a continuously moving cathode (as shown) the electrolyte may be stirred. In an alternative form of the method, instead of using a pulsed D.C. voltage with mechanical agitation of the electrolyte, the applied voltage may alternate from a positive to a negative value during its cycle.

The rod 55 that operates for lateral displacement of the pincers is connected to a block 1 guided in a slideway 2 in the link X<8> that causes rotation of the pincers. The block 1 is. formed on one end of a member 3 having at its other end an inclined slot 4 guided on a roll 5 carried on an extension 6 of the pivot X<12>, the slot being equal in length to twice the diameter of the roll. A spring-pressed plunger 7 controls the position of the roll in the slot. The pincer is in front of the right-hand, or the left-hand tack-inserting position according as the slot is in its lower or its higher position. Movement of the member 3 is brought about by a link 8 pivoted to one arm 9 of a lever fast on a shaft 10 having an operating-handle 12. The second arm 13 of this lever has engagement with a thrust-rod 14 con. nected to the lever F (see Specification 27290/12) that controls the position of the bunter or thick edge gauge.
