Title: Method of casting metals
IPC: B22D7/10
Filed: 1970-07-16
Abstract: 1313008 Casting ingots DAUSSAN ET COMPAGNTE 16 July 1970 [8 Aug 1969] 34570/70 Heading B3F A metal ingot is cast by a bottom- or toppouring method which includes positioning at the top of an ingot mould B before or during pouring a cover A. The cover A is held to the ingot mould B by clips 7 and wedges (2, not shown). Apertures 3a, 3c are provided so that the molten metal can flow above the cover A. The central aperture 6 is provided for toppouring. When bottom-pouring, a charge of exothermic powder is placed upon the metal M rising in the mould and pouring stopped as soon as the metal reaches the bottom of the cover. Pouring is then continued at a slower rate to a level N above the top of the cover. Preferably the cover is of a composition (containing refractory and/or exothermic ingredients) which breaks down into granules under the heat, of molten metal. Lugs 12 can be provided which lie above the level N after metal pouring. As shown in Fig. 4, the cover has decomposed to form a layer 29 on the surface of the cast ingot M1. Metal has a been chilled by the cover to form a cap 25 with vents 28 formed by the lugs 12. When top-pouring, pouring is stopped and exothermic powder is placed upon the molten metal when it has reached a height just below the position where the lower wall of the cover is to lie. The cover is placed in the mould and pouring continued slowly to the level N. In the embodiment shown in Fig. 5, a cover A1 lies upon hot-top slabs El in the head of an ingot mould. Metal is top-poured over a distributer 21 and enters cavities 15 behind the hot-top slab. This results in chilling a band of metal around the hot-top metal as well as chilling a cap over the metal 29 that the ingot cast can be removed from the mould whilst the hot-top metal is still liquid.

Abstract: 1,134,547. External shoe-drum brakes; fluidpressure brakes. J. BINNS. 6 Aug., 1966, No. 35307/66. Headings F2E and F2F. [Also in Division B3] In a lathe or boring mill the workpiece is secured to a rotating face-plate 18 having a centre 20 thereon, and the face-plate is stopped during a temporary pause in the machining operation by brake shoes 80. The face-plate is driven by a shaft 16, Fig. 2, through gears 28, 26, 30, planet gears 32, internal ring gear 34, and clutch member 38. Member 38 is moved by a rod 40 actuated by an hydraulic cylinder 42, and has two sets of splines 44, 46. When the member 38 is moved to the left, Fig. 2, splines 44 engage external splines 52 of a fixed clutch ring 54 fixed to the headstock, and splines 46 engage external splines 50 of ring gear 34, thereby locking the ring gear and providing a slow speed drive to face-plate 18. To rotate the face-plate at a fast speed, clutch member 38 is moved to the right, splines 46 engage external splines on a clutch ring 64 fixed to the face-plate, and splines 44 engage splines 48 of ring 34. Each brake comprises a shoe 80 having a liner 82, Fig. 3, which is moved towards and away from a braking surface 74 on face-plate 18 by a double-acting hydraulic cylinder 84 connected to the face-plate by a link 88. A fixed lug 102 on a bracket 98 has a floating connection with one end of the shoe by means of a link 104, to prevent the face-plate moving the shoe, and the latter is limited in its withdrawal from the faceplate by a stop 110. The brake shoes are constantly urged towards the face-plate by springs 114 whose tension can be adjusted by nuts 126. An electric switch 134 is provided for each shoe and they are arranged so that the brake shoes will depress them when they are withdrawn from the face-plate, so as to close an electric circuit which includes a headstock drive motor. In operation, fluid pressure is supplied to cylinders 84, by a constant pressure pump 138, Fig. 10, through a spool valve 148, which is shifted longitudinally by either a brake-setting solenoid BS, or a brake-release solenoid BR, and this pressure, along with the pressure of the springs 114, applies a braking force to the shoes. A workpiece is secured to the face-plate, a starter is actuated, solenoid BR is energized, fluid is supplied to the opposite end of each cylinder 84 and the brake shoes are withdrawn, the headstock motor and a time relay are energized, and the motor circuit is closed. After a period of about three seconds current flows through switches 134, after the brake shoes have been retracted, due to the closing of the starter switch, and the workpiece is machined. If any shoe fails to withdraw, the relevant switch 134 is not closed, and the current supply to the drive motor is interrupted.

Abstract: 1280982 Feeding bobbins to endless conveyers SCHWEITER ENG WORKS Ltd 24 July 1968 [27 July 1967] 35389/68 Headings B8A and B8S [Also in Division D1] Apparatus charging a textile machine with bobbins automatically maintains therefor a continuously available supply from a loaded supply container or magazine in accordance with the demand of the machine. Such apparatus comprises a bobbin transport device having a bobbin-elevating path inclined with respect to the vertical, a pair of vertically spaced bobbin supply containers which are displaceably mounted relative to the device, positioned transversely thereof and each having an outlet opening facing same. Positioning mechanism controllable as a function of the depletion of bobbins in one of the containers and the presence of bobbins being carried by the device actuates alternate positioning of the containers. In the operation of the apparatus shown, a transport band 1 is driven stepwise through an incremental distance equal to the interval between adjacent compartments between ledges 2 and in accordance with the electrically measured demand for bobbins 30: when a preparatory container (22) for the machine being loaded needs another bobbin, the band 1 is advanced one step to bring the next successive compartment to the delivery station at the top of the run of the band and a bobbin thereat is discharged to a conveyer (not shown) which transfers it to the preparatory container. The delivery compartment of the band 1 is maintained loaded by a sensor 21 therefor which completes a circuit to keep motor 5 running so long as such compartment remains empty. In order to load the band with bobbins 30, loaded containers or magazines 8 are placed on platforms 6 and 7 the lower of which is electrically locked in advanced position whereat successive bobbins are transferred singly on to ledges 2 as the band moves on its upward flight. When the container is exhausted and the band at the level of the container 8 on platform 6 is devoid of bobbins (conditions detected by a feeler 18) a solenoid 14 is energized to unlock the associated lever member 9 of a system of such members which then rotates about pivots 10 under the greater weight of the loaded upper container 8 which thus moves into a locked bobbin-feeding position in relation to band 8. This gravity-operated mechanism may be replaced by a solenoid-operated advancing mechanism (not shown). The exhausted container 8 is replenished whilst the freshly applied container supplies bobbins to the band. The operation of solenoid 14 may actuate visual and/or aural signals. Each platform 6 or 7 may be replaced by a sled movable on runners or wheels by electromagnetic apparatus (not shown).
