Title: Method of continuous delivering of fluid-gas mixture - involves having gas separated from fluid-gas flow between first and second level above which it is directed
Inventor: SCHIEL CHRISTIAN
IPC: F04F1/18
Filed: 1994-01-20
Abstract: A method has gas separated from the fluid-gas flow between the first and second levels. The gas is directed until above the second level. A fluid main flow is separated from the fluid-gas flow, and a fluid-gas flow is directed to a level above the separation point. One rise of the fluid-gas column throttles the total flow, that is the flow of fluid and gas to the separation point. USE/ADVANTAGE - For delivery from one level to a second level at a certain flow rate, e.g. for paper machine drying cylinders. It has a stable flow of fluid-gas mixture without pulsation, it has min. gas suction.

Title: Safety procedure for train negotiating railway section
Inventor: SCHAEFER HARALD
IPC: B61L23/22
Filed: 1994-02-25
Abstract: To provide safety for the trains moving in individual sections of railway track, their actual positions are determined and communicated regularly to a central administration unit. This then stores either a "free" or "occupied" condition for each section. A "free" section gives a permission-to-travel signal to a train approaching the section, and instead of the "free" condition, the "occupied" condition is stored while the train is crossing it and until the train has left it completely. Permission for a train to cross into an "occupied" section is rejected. If necessary, the train control unit instigates emergency braking in order to prevent entry of a train into a section without permission.

Inventor: ROTHLEY MANFRED DIPL ING
IPC: G01P15/00
Filed: 1994-10-12
Abstract: The proposal is for a device and a process for the simultaneous determination of a rate of rotation W and an acceleration atr transverse to the axis of rotation. Said device has at least one acceleration sensor (1, 2) on each of at least two sections (3, 4) fitted in such a way that its axis (Z1, Z2) sensitive to accelerations (ac1, ac2, atr) does not lie in the plane formed by the axis of rotation (D) and the velocity component (v) of the oscillation. In implementing the process, the device is rotated about the axis (D) at a rotation speed corresponding to the speed W to be determined, and simultaneously the device is caused to oscillate at at least two sections (3, 4) with a velocity component (v1, v2) perpendicular to the axis of rotation (D). With the symmetrical fitting of identical acceleration sensors (1, 2) to the device, the rate of rotation W and the transverse acceleration atr can be obtained in a simple manner by adding or substracting the measurement signals detected in the acceleration sensors (1, 2).

Title: Mechanical pressing machine
Inventor: KATO HEIZABURO
IPC: B30B15/06
Filed: 1994-10-24
Abstract: In summary, the present invention provides a mechanical pressing machine which is constructed and functions specifically in the following manner: a flywheel is arranged securely on an input shaft, and a drive cam disc or cam plate is arranged securely on the input shaft between the opposite ends thereof, and a torque-compensating plate cam or cam disc is further arranged on the other end of the input shaft. A cam disc or cam follower, in particular a cam roller, which is arranged on a distal end of a piston rod of a device which generates an elastic force, is held in pressure contact with the torque-compensating plate cam or cam disc in such a way that a load variation which is generated on the input shaft is compensated. In the device which generates the elastic force, a compression spring, in particular a helical compression spring, or an air spring or pneumatic spring, is preferably used. With this construction, a periodic inertial load variation, which is generated repeatedly upon each revolution during the operation of the mechanical press, is compensated by the system for reserving energy and is accordingly cancelled out, as a result of which the energy is compensated so that variations in the revolution of the input shaft are cut out and...
