Abstract: A rotatable member (3) has on its outside surface a contoured surface portion (15) which widens conically upwards in diameter, is contiguous with a lubricant storage chamber (14) and extends axially to near a bearing (11) by which the rotatable member (3) is rotatably mounted in a housing (4). Lubricant discharging downwardly by gravity from the bearing (11) returns upwardly along the surface part (15) and reaches a zone which is below the bearing (11) and from which the same takes up lubricant. The bearing (11) is therefore supplied with lubricant during the rotation of the rotatable member (3) so that uniform lubrication in a thin layer is ensured. The mounting is used more particularly in a cap of a cap spinning machine or cap twisting machine.

Abstract: In the donning and doffing operation of a spinning machine, a tube (20) is pushed onto a packaged tube (14), whereby the thread (7) remains unbroken. The package (14) and the tube (20) are rotated together, until a few turns of the thread (7) are wound on to the tube (20). The tube (20) is subsequently held and the packaged tube containing the package (14) is removed. Subsequently, the empty spindle (15) is guided into the tube (20) for subsequent spinning operations without the necessity for removing overwindings which normally occur.

Abstract: A method and apparatus for providing improved security for a personal identification number (PIN) in a personal identification and verification system of the type wherein a time dependent nonpredictable code is generated at a device in the possession of the individual, which code is unique to the individual and this code is communicated to, and compared with a nonpredictable code generated at, a central verification computer. In this system, the PIN is mixed with the nonpredictable code before transmission of these values to the central verification computer. a nonsecret code is previously transmitted to the central verification computer and is used to retrieve the PIN and the appropriate nonpredictable code for the user. These values are used to strip the PIN from the transmitted nonpredictable code and the stripped PIN and remaining nonpredictable code are compared with the corresponding retrieved values in order to determine verification.
