Abstract: 1500950 Introducing metal DANSK INDUSTRI SYNDIKAT AS 21 Aug 1975 [11 Sept 1974] 34850/75 Heading B3F A casting apparatus in which sand mould parts 2 are successively produced and fed along a track 3 to form casting cavities 4 across the joints between adjacent mould parts with upwardly open inlets 8, is characterized in that a pouring tundish 5 rests sealingly on top of the mould parts, and has an outlet 7 which successively communicates directly with the mould inlets 8 as the mould is moved stepwise along the track 3, e.g. to a cooling and knock-out station. The tundish 5 can be adjusted along the feed direction and laterally thereto to be aligned with the inlets 8. It may also be arranged for the tundish to travel forward with the mould during pouring and then return to its start position. The tundish includes heaters 18 and a level control arrangement 19, 20, 22. A wear plate 6 is provided on the bottom of the tundish and a paper, plastics or metal foil sheet 28 may be fed around rollers 24, 25 and between the tundish and the mould top to prevent damage to the mould top. At a pouring alignment the sheet 28 is burnt through by the molten metal. The tundish 5 is supported on spring biased columns (11) (Fig. 2, not shown) to reduce contact pressure on the mould top. The mould top may be covered with graphite powder to reduce friction, and may be stabilized by a hardening binder.

Title: Universal joint flexure assembly
IPC: F16D3/00
Filed: 1972-07-31
Abstract: 1348618 Flexible couplings SINGER CO 31 July 1972 [14 Oct 1971] 35706/72 Heading F2U [Also in Division G1] In a free-rotor flexible suspended gyroscope, a rotor 10 and drive shaft 12 are interconnected by a two-axis universal flexure hinge 14 comprising inner and outer hinge units, each unit comprising a middle gimbal 28,20 which is adjustable so as to compensate dynamically spring rate torques which would occur when a gimbal 28, 20 moves with the rotor 10. Each unit further comprises upper 30, 22 and lower 26, 18 gimbals connected to the respective middle gimbal 28, 20 by flexure bars 32, 24. The upper gimbals 30, 22 are connected to each other and to the rotor 10, the lower gimbals 26, 18 being similarly connected to the drive shaft 12. The arrangement is such that the middle inner gimbal 28 moves with the rotor 10 when it flexes about one axis whilst the middle outer gimbal 20 moves with the rotor 10 during flexure about a second, orthogonal axis. Further, the inner unit provides stiffness along the Z axis whilst the outer unit provides radial and torsional stiffness, the units complementing one another to permit the rotor 10 to pivot relative to the shaft 12 about any axis perpendicular to the Z axis. Compensation for inertia and mass unbalance of the middle gimbals 28, 20 is required in order to overcome error producing factors. For example, as the rotor 10 pivots, a positive restoring force is produced within the flexure bars 32, 24 and a negative force results due to the inertia of the middle gimbals 38, 20. The inner middle gimbal 28 is compensated by the inclusion of a rod 38 and sleeve 46, the outer middle gimbal 20 being provided with compensation weights suitably and adjustably positioned.
