Title: Open-end spinning machines
IPC: D01H4/12
Filed: 1973-07-19
Abstract: 1406186 Open-end spinning; rocking mechanism FRIED KRUPP GmbH 19 July 1973 [20 July 1972 34495/73 Heading DID A rocking mechanism for rotor housings of open end spinning machines in which the rotor housing 1, with a spinning rotor 3 inserted therein by its journal 3a, can be rocked about a horizontal axis 2 parallel to the machine front 14 from the operating position in which it abuts at the top against the opening roller housing 7 and the opening roller 13 extends into the rotor 3, is characterised in that the rotor housing 1, which can be rocked outwardly from the machine front 14 in relation to its rocking axis 2 disposed beneath its operating position, can be moved before and after rocking downwardly and upwardly respectively in relation to the underside of the opening roller housing 7 in the direction of the axis of the rotor 3 when in the operating position, and is also characterised in that an actuating lever 9 for the rotor housing 1 is rotatably mounted on the rocking axis 2 and is so arranged that the lever 9 moves with the housing 1 during its rectilinear movement through a member 10 acting as a connecting rod for a crank drive 15 and connected at one end to the actuating lever 9 at a point 16 spaced from the rocking axis 2 and at the other end 17 to the rotor housing 1 and forms with the rotor housing during the rocking movement a rigid rocking unit. During the initial movement of the actuating lever 9 in a counterclockwise direction about axis 2, the crank drive 15 is caused to pivot on the axis 2 and the connecting rod 10 causes sleeves 5a of the rotor housing 1 to slide on arms 5 compressing the springs 6. The rotor housing 1 thus moves downwardly relative to the housing 7 in the direction of the rotor axis and a cam surface 8 on the housing 7 is disengaged. The lever 9 is urged against the rotor housing by a spring and further counterclockwise rotation of the lever causes the crank drive 15 to pass through the bottom dead centre position and downward movement of the housing ceases. By virtue of the lever being urged against the housing 1, the lever 9 engages a notch 12 in the housing 1 and further rotation of the lever rotates the housing about the axis 2. In this position, the rotor 3 can be cleaned or changed. Rotation of the lever 9 in a clockwise direction then reverses the procedure, the rotor housing 1 abutting against a suction head 20 on the underside of the housing 7 and the cam surface 8 guiding the housing 1 into the correct operating position. In the preferred embodiment, the rotor housing 1 is mounted on a rocking arm 24, and the lever 9 is bent in the direction away from the machine front 14 around a delivery mechanism 23 axially spaced from the operating position of the rotor 3.

Title: Improved process for producing magnetic thin film elements and elements produced thereby
IPC: C25D5/54
Filed: 1964-08-28
Abstract: Magnetic thin film elements are made by plating a magnetic film e.g. Ni/Fe alloy, on a metal or metallized substrate which is pre-coated with an electrically conductive amorphous material consisting of carbon, silicon, or germanium, preferably formed by vapour deposition.  The amorphous coating is stated to interrupt the influence of the crystal structure of the substrate on the magnetic film. In an example, a glass substrate is metallized by vapour deposition first with chromium (100 A thick), and then gold (100A), and with germanium (300A thick).  The final electroplated film of Ni/Fe alloy is 1000 A thick and is deposited while applying a magnetic field of 100 oersteds.  Graphs are given showing the relation between the thickness of the amorphous film and coercive force of the magnetic film.
