摘要:
An information disk store possesses an air circulation system in a substantially sealed housing, by means of which system, which includes a channel for directing air to the end of the hub on which the disks are mounted, and a low-pressure compartment that is shut off from the disk compartment by a main filter, a first positive pressure gradient from the bottom to the top of the housing is set up in the peripheral space adjacent to the disks. It is advantageous to also set up a second positive pressure gradient in the direction of rotation of the disks, in the peripheral space adjacent to the disks. The novel air circulation system can be used with advantage in all information disk storage systems in which the write and read operations may be adversely affected by dust and dirt.

A magazine for transport and operation in a device for a plurality of film-like flat recording media, especially of floppy disks. Details of the magazine according to the invention relate to a part which receives the recording medium, a lid, a mechanism for locking the said parts together, and a guide and gripper part.
摘要:
A change-over mechanism for disk-shaped recording media, especially for magnetic films in a sleeve, is provided with a magazine and with selector, transport and drive mechanisms which can provide any desired access to any recording medium and permit trouble-free operation. The mechanism can be used for floppy disks and any type of film-like or rigid recording media.

Disclosed is a vehicle, in particular rail vehicle, with a wagon body and an running gear on which the wagon body is supported, wherein the wagon body and the running gear define a vehicle longitudinal direction, a vehicle transverse direction and a vehicle height direction. A tilting mechanism is arranged between the wagon body and the running gear, which is designed to impose, during a transverse displacement in the vehicle transverse direction, upon the wagon body a rolling motion about a rolling axis parallel to the vehicle longitudinal direction. The tilting mechanism comprises a transverse decoupling device, which is designed to reduce the stiffness of the tilting mechanism against a pure transverse displacement of the wagon body with respect to the running gear. The invention furthermore relates to a corresponding tilting mechanism.
摘要:
A rail vehicle having a car body, which is supported on a running gear by a spring device, and a rolling compensation device, which is coupled to the running gear and the car body. The rolling compensation device may be arranged kinematically in parallel to the spring device. The rolling compensation device counteracts rolling motions of the car body toward the outside of the curve about a rolling axis during travel in curves. The rolling compensation device, in order to increase the tilting comfort, is designed to impose, in a first frequency range and under a first transverse deflection of the car body, upon the car body, a first rolling angle about the rolling axis, which corresponds to a current curvature of a current section of track being traveled.
摘要:
The present invention relates to a method for oligomerization or polymerization of ethylene and/or alpha-olefins utilizing reactor equipment and other equipment wherein starting material comprising monomer(s), catalyst, cocatalyst and solvent is transferred to the reactor equipment via first piping, and product material comprising oligomer and/or polymer, non-reacted monomer(s), catalyst, cocatalyst and solvent is discharged from the reactor equipment via second piping, characterized in that the first piping, second piping, reactor equipment and/or other equipment are flushed with a product fraction obtained by said or a respective previous method prior to and/or after that oligomerization or polymerization method.
摘要:
The invention relates to a measurement bearing, in particular for a wheel set of a rail vehicle, having a rotational axle and at least one first bearing ring (103), wherein the first bearing ring (103) defines a main supporting direction and a circumferential direction extending transversely with respect to the main supporting direction, and the first bearing ring (103; 203) is designed to take up bearing forces which have at least one force component in the main supporting direction, and during operation said bearing forces are applied to the first bearing ring (103) via a plurality of rolling bodies (104). The first bearing ring (103) has at least one first recess (105) in which a sensor device (110) is arranged, wherein the sensor device (110) is designed to sense a sensing variable which represents the bearing forces which are applied to the first bearing ring (103).

The invention relates to a module for reproducing a transmitter signal (xactE). A control device (1) is coupled to a driving device (4a) for controlling a machine while being coupled to the module (5, 5′) via a data bus (7) for exchanging data. A reproduced transmitter signal (xactEn) is determined from a reference value (xdes) that is predefined by the control device with the aid of the module (5, 5′). The module (5, 5′) is logically coupled to the control device (1) via the data bus (7) in such a way that the module (5, 5′) is projected in the same way as the driving device (4a) from the perspective of the control device (1). The inventive module (5, 5′) for reproducing a transmitter signal (xactE) thus makes it possible to project, start, and adjust the dynamics of the machine in a simple manner.
