Title: Disc record player
IPC: G11B33/06
Filed: 1975-10-23
Abstract: 1526056 Record player FUJI TELECASTING CO Ltd 23 Oct 1975 [22 May 1975] 43651/75 Heading G5R In a record player a pick-up arm 11 including pick-up stylus 15 is mounted on a bracket 19 for vertical and horizontal pivoting 13, 14 movement above the middle groove of a record D, of the type described in Specification 1,493,871, having a plurality of endless circular grooves and is positioned to playback a selected groove by the use of an indicating device 17 carried by the arm and an underlying scale 32 mounted on the chassis 12 of the player. The scale can be manually raised by control lever 36 thereby raising the pick-up arm from the record so that it can be manually positioned using indicating device 17 and scale 32 which is calibrated in groove positions. Positioning is assisted by a detent 35 on the arm engaging notches 34 on the scale. Lowering the lever lowers the pick-up stylus into the selected groove. The inward force produced on the pick-up arm due to its geometry and the frictional engagement of stylus and record is compensated by a magnet 25 mounted on bracket 19 which co-operates with an iron member 28 mounted on the pick-up arm. The turntable is driven at slow speed in the range 1-8 r.p.m. and carries a magnetic member which co-operates with a magnetically operated switch on the chassis when the stylus is scanning sector g c of the record where the information recorded in each groove commences. The switch is in parallel in the supply circuit to the turntable drive motor with a further switch which is opened when the pick-up arm is raised and ensures that on raising the arm the turntable is stopped with the sector g s under the stylus.

Abstract: 1408869 Degassing centrifuge H RUMPF 21 Sept 1972 [21 Sept 1971] 43781/72 Heading B2P A liquid 1, Figs 1 and 2, is degassed by flowing it in the form of a film 3 on the inner surface of a centrifuge hollow rotor 2 having an open end and, before the liquid film leaves the open end of the rotor, by separating it into a portion 5 with a high gas bubble content and a portion 13 with a low gas bubble content. The portions 5, 13 are separated from each other by an annular cutting edge member 4 which can be adjusted to the thickness of the liquid layer with low bubble content. The member 4 directs the portion 5 over an overflow member 8 against the cylindrical wall 9 of a collecting duct 6 which is under vacuum, whereby partial separation of the gas bubbles from that portion of the liquid takes place, the partially degassed liquid being recycled through the rotor via a line 7. The portion 13 of the liquid film leaves the rotor through tapered draining ducts 10 which are provided in the rotor and are backwardly curved in relation to the direction of rotation of the rotor. The ducts direct the portion 13 at a low circumferential and radial speed and preferably tangentially against a conical stationary lid 11 of a draining duct 12. In a modification, Fig 3 (not shown), the portion of the liquid with low bubble content is discharged without contact with gas through an annular slit or perforations (14) in the rotor into liquid (15) contained in a gas-tight annular chamber adjacent the open end of the rotor. In a further modification, Fig 4, the portions of the liquid with low and high bubble content after separation from each other by the cutting edge 4 are respectively discharged from the centrifuge rotor by means of scoops 18 and 19 which may be stationary or rotate at a slower speed than the rotor.
