Title: Method of accelerating the reaction in aluminothermic processes especially in their application to welding
IPC: C22B5/06
Filed: 1930-11-17
Abstract: A method of accelerating the reaction is thermo-aluminic processes, particularly for welding, consists in adding to or alloying with the aluminium of a normally constituted mixture a small amount of one or more elements such as calcium, sodium, and magnesium, which posses a greater affinity for oxygen than is the case with aluminium.

Title: Printer

IPC: B41J25/20
Filed: 1966-08-03
Abstract: 1,097,843. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 3, 1966 [Aug. 21, 1965], No. 34711/66. Heading B6F. Typehead carriages; power-assisted type actions; machines with type characters upon spherical heads; combination type selecting mechanisms; printing and perforating machines; perforated record input arrangements; accenting arrangements. A typewriter having an interchangeable truncated sphere typehead (not shown) mounted on a traversable carriage (not shown) and a perforating machine producing a record tape, which may subsequently be used to control the type selection of the typewriter is provided with an accent key 1, Fig. 1, which when depressed causes first a backspacing action to occur and then the printing of the accentuation mark associated with the key. Depression of key 1 causes key lever 3 to depress an interposer 11 which is latched by spring 19 so that a lug 29 may depress a back spacing coil and effect the back spacing by rocking of lever 37 on engagement with its lug 35 and consequent rocking of a bellcrank 41 which depresses a backspace interposer 45. Meanwhile the printing cycle is suppressed in that the accentuation interposer 11, which is provided with lugs 21 which co-operate with the type character selection bails 23, has its clutch bail 25 actuating lug 27 removed. Following completion of backspacing the backspace interposer 45 pivots the bellcrank 41 which rocks the clutch bail 25 through an intermediate lever 47 whereupon a cam shaft 30 is rotated though a half-revolution to displace the interposer 11 whose lugs 21 actuate the type selection bails 23 to complete the printing cycle by printing the accent mark. Key interlocks; case-shift key actions.-Depression of key lever 3, causes the keys of the whole keyboard to be locked until the interposer 11 is returned to its original position by the rotation of cam-shaft 30, the locking being effected by a lug 15, on the key lever 3, which displaces a series of interlocking rollers mounted slidably on a rod 17. Also accidental depression of the case-shift key lever 53, Fig. 2, is prevented by providing its extension arm 55 with a lug which has two spaced notches 57, 59, whereby one of the latter is engaged by a panel 51 on the backspacing bail 31 depending on the position of the caseshift key lever 53.

Title: Improvements in and relating to cathodes for electron discharge devices
IPC: H01J9/04
Filed: 1928-11-26
Abstract: 316,536. Just, A. July 30, 1928, [Convention date]. Vacuum tubes. - Alloys of iron with the alkali. alkaline-earth, or rare earth metals when worked and drawn into wire are used for thermionic cathodes. In the manufacture of the alloys, chemically pure iron is produced by heating iron oxide in hydrogen, after which the iron so produced is melted in a lime crucible and the active metal, e.g. barium, is added in an amount not exceeding 20 per cent. Strontium, calcium and lanthanum may replace the barium, or mixtures of alloys of these metals with iron may be employed. When the alkali metals are to be alloyed, chemically pure iron and an organic salt, e.g. potassium tartrate, are heated to a dull red heat, the alloy of iron and potassium so obtained being used for addition to a further mass of molten iron. Increase of ductility is obtained by reducing the amount of active metal in the alloy. Annealing is effected in an inert gas, preferably hydrogen.

Abstract: 818,856. Knot tying devices. GOODYEAR TIRE & RUBBER CO. Nov. 8, 1957 [Feb. 12, 1957], No. 34838/57. Class 112 A knot-tying device, Figs. 1, 2, 8, comprises a base 1, spaced-apart members 2, 3 which rise from the base, means 7 rotatably mounted between said members for twisting a pair of cords together, means for releasably holding the cord ends on the cord-twisting means, and means for rotating the latter a plurality of turns. The device ties the ends of cords 24, 25 into a double-ended, or barrel, knot as shown in Fig. 10. Member 7 is formed in its journal ends with cord-receiving slots 8 which register with similar slots 6 formed in the upper edges of members 2, 3. A gear pinion 9, carried by member 7, is also formed with a cord-receiving slot 10 and meshes with a gear 11 carried by a shaft 12 journalled in members 2, 3. A pin 14, carried by gear 11, normally rests against a fixed stop 16. To operate the device pin 14 is turned in the clockwise direction, whereby a spring 13 is stressed and pin 14 is finally held by a face 18 on a latch bar 15 biased upwardly by a spring 17. The cords 24, 25 are then threaded through the slots 6, 8, 10 to lie on opposite sides of guide members 19 upstanding from member 7. Bar 15 is then depressed to release pin 14, which returns to stop 16, whereby member 7 is rotated to twist the cords together a predetermined number of turns at each end of members 19. The cord ends are then drawn between the outer faces of an inverted U- shaped spring member 21 and the adjoining faces of members 19, whereby the cord ends are releasably clamped. Continued downward movement of the cord ends brings the latter into contact with a knife blade 22 to sever the ends as shown in Fig. 8. The twisted configuration is then drawn upwardly and outwardly off the members 19, whereby the cord ends are held in the loop formed around the latter, and the twisted ends turn inside out to assume the configuration shown in Fig. 10. In a modification, Fig. 3, the cord end-holding member 21 is in the form of a helical spring, said ends being drawn around the opposed edges of a separator finger 20 before being engaged with member 21. In a further modification, Fig. 5, the cord ends are clamped between a central finger 20 and members 21 biased inwardly by springs 23. The gears are normally arranged to twist the cords together three turns. In the case of materials such as nylon the cords are preferably twisted together five turns.

Distributing matrices.-The second elevator includes an elevator lever pivotally mounted on the machine frame for arcuately transposing the matrices between the transfer channel and the distributer mechanism, a yoke member pivotally mounted on the elevator lever, a bar for supporting the matrices during elevation thereof pivotally fastened to the yoke, and a rod-like member pivotally and slidably mounted at one end on the machine frame and pivotally fastened to the bar at its other end and operating to maintain constant vertical alignment of the matrices during arcuate movement thereof. The elevator lever 24, Figs. 3 and 5, is formed on a hub 34A rotatable on a shaft 23, on which hub is formed an arm 34 to which motion is conveyed through a compression-spring 33 from an arm 28A formed on a hub 28 rotatable on the shaft 23, which hub 28 is oscillated by a cam 10 through a roller 14, link 30, and arm 29 formed on the hub 28. The arm 24 has pivoted thereto at 42 a yoke 41 carrying pivotally at 58 a head 57 supporting the bar 40 for receiving matrices. A nose 54 of the yoke is urged against an adjustable screw 55 by a spring 51. Rigid with the bar 40 is a plate 62 to which is pivoted a rod 25 pivotally supported intermediate its ends on a member in the lever 24 and mounted at its front end by means of a slotted bracket 43A on a stud 43 on a washer member 20 angularly adjustable on the shaft 23. A spring urges the rod to the right. Pads 59 on the head 57 engage the distributer channels and a slide 60 engages the intermediate channel alignment post 61. The mounting of the parts 24, 41, 40, 25 maintains the bar 40 vertical, while allowing horizontal movement of the head 57 during engagement and disengagement with the distributer and vertical movement during engagement and disengagement with the intermediate channel. A lever 66 pivoted to the machine frame at 67 is normally in the path of a projection 65 of the hub 34A to prevent descent of the second elevator except at the correct moment in the machine cycle, when an extension cam on the line delivery cam 69 moves the lever 66 out of the path of the projection 65.
