Title: Improvements in or relating to the magazine entrances of typographical composing machines
IPC: B41B11/06
Filed: 1926-08-26
Abstract: 264,089. Intertype Corporation. July 1, 1926, [Convention date]. Magazines for type-bar-making machines.-Relates to (1) the mounting of the magazineentrances, and (2) means for stopping the distributor when the entrances are moved into the open position, or when a matrix jams. (1) In order to secure a downward movement of the entrances to enable them to clear the distributorscrews before they are moved rearwardly into inoperative position, the entrances 24, 26 are mounted in a frame 27, which is connected by pivots 30 to a second frame 28 mounted on pivots 29 in fixed brackets 17. Springs 65 hold the entrances in operative position, the frame 27 bearing on set-screws 40 on the frame 28, which in turn rests on set-screws 68 on the brackets 17. The entrances can be rocked open by means of a handle 82, the frame 27 first moving downwards until it meets an abutment 42 on the frame 28, and the two frames then turning together about the pivots 29. The outward movement is arrested by a pivoted stop 75, which can be moved out of position in order to give a further movement of the entrances. To enable the entrances to adjust themselves to the upper ends of the magazines, they are separately mounted on pivots 55 in the frame 27. The pivoted movement is limited by bars 60, 61 on the entrances, which lie between opposed abutments 62, 63 on the frame 27. Guide-fingers 70 an the upper, entrance are adapted to engage the top of the upper magazine 14, and a guide-lip 72 on the lower entrance is caused :by a spring 64 to engage the underside of the lower magazine 13. In machines having auxiliary magazines alongside the main magazines, the entrances of the auxiliary magazines are carried by an extension of the frame 27, and an open bearing on the machine frame receives a pivot pin on the extension, in order to support the entrances when in operative position. (2) The means for stopping the distributor when the entrances are opened, or when a matrix jams, camprisee a sliding clutch-operating, bar 96, located between the entrances, and having lugs to engage the flexible partitions of the entrances. Specification 14582/90 is referred to.

Abstract: 735,085. Refining metals and alloys; producing titanium ; crucibles. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 5, 1953 [Aug. 28, 1952], No. 21576/53. Classes 72 and 82 (1). [Also in Group XXII] Gaseous impurities, particularly oxygen and nitrogen, are removed from Ti, V, Ta, Cr, Mo or W or from alloys formed exclusively or predominantly of these metals by locating the metal, after it has been pressed in the powdered form to the desired shape, in molten cerium or in cerium vapour. The pressed metal powder may be sintered before treating it in the cerium, or the temperature of the cerium may be high enough to effect sintering during the treatment. In one form of apparatus described for carrying out the treatment, Fig. 1, the refractory metal compact 11 together with metallic cerium 14 is placed in a container 12 of molybdenum or iron lined with tantalum. The cerium may be in the form of mischmetal. The container 12 rests, via an insulator 15, on a water-cooled metal plate 16 and is covered by a bell-jar 17 filled with argon at reduced pressure. The container is heated, by a high-frequency coil 23, to 1000-1300‹ C. to melt the cerium and is kept at that temperature for some hours, e.g. 5 hours at about 1000‹ C. or 1 hour at about 1300‹ C. After cooling, the cerium is separated from the refractory metal by leaching with dilute hydrochloric or acetic acid. In another form of apparatus similar to that described above, the pressed refractory metal is supported in a cage which is first lowered into the molten cerium and then, after a suitable time, raised to allow treatment by the cerium vapour. A process for the production of purified Ti is also described in which a titanium compound, e.g. titanium oxide, is first partially reduced by a reducing material comprising mainly magnesium, e.g. a magnesium-rich alloy, and completing the reduction with a reducing material comprising mainly calcium, e.g. a calcium-rich alloy. The Ti produced is separated and pressed and the compact is treated in fluid cerium to remove the gaseous impurities. The reduction steps may take place in iron crucibles lined with magnesium oxide and calcium oxide respectively. The Specification also refers to the removal of oxygen from Ti, Zr, V and Hf by treatment in molten calcium or calcium vapour.

Class 142(2) A lens fabric, which may be of hemp, jute, or wire, is produced on a loom having only two heald frames S, I, each frame moving transversely to s'hog the warp threads and also moving vertically to form the shed. The warp threads pass through eyes in needles 5s, 5i mounted in each frame. The frames are moved transversely by guides 10, 11 engaging the sides of the frames and actuated by a rod 14 and a rocker 8. The left and right hand rockers are connected together by the heald frames and move in conjuction with each other. The rod 14 may be operated by cams on the shaft that effects vertical movement of the frames. The rod 14 could be arranged vertically. The frames are connected together so that their vertical movements are synchronized. In an alternative embodiment (Fig. 10) only one frame is moved transversely, this movement being effected by a rod 14, an arm 15 and a guide 10. An arm 15 at the other side of the frame is similarly operated or may be connected to the first arm. Alternatively provision could be made for maintaining the second guide against the frame.
