Title: Brake device for railway vehicles, especially a shoe brake for at least two sets of wheels
IPC: B61H15/00
Filed: 1987-11-04
Abstract: The largely automatic adjustment of the brake rods of brake devices, especially shoe brakes for rail vehicles, is generally achieved by means of single-acting or double-acting brake slack adjusters at the beginning of the corresponding brake gear chain. With longer brake gear chains, re-adjustment can no longer be compensated for by the brake slack adjuster alone and the positions of the brake levers at the end of the chain may become so incorrect that adequate functioning of the brake device is no longer guaranteed. So that additional manual adjustment of the brake gear can be largely dispensed with and the efficiency of the brake device improved, on a brake device of this type at least one additional brake slack adjuster is fitted in series in the brake gear chain after a double-acting brake slack adjuster. The necessary adjustment travel for the respectively preceeding brake slack adjuster is determined by the sum of the necessary degrees of play in the associated friction pairings to be acted upon and the required adjustment travel to be established comparably in any succeeding brake slack adjuster. <IMAGE>

Title: Ultrasonic transducer and current loop transmitter
IPC: G01M3/24
Filed: 1988-11-04
Abstract: Ultrasonic vibrations indicating trouble at remote locations are detected by sensors (20) spaced in the vicinity of expected trouble. These sensors have weather resistant transducers that convert ultrasonic vibrations from a leak in a conduit, electrical arc, bearing vibration or the like, into an electrical signal. In the sensor there are circuits that amplify the electrical signal and transmit it with a current loop transmission system over a twisted pair of wires to a central control and analysis computer (30). The amplification of the signal at the sensor is controlled by a signal from the central computer which changes the gain increments until the sensor circuits are not saturated by the ultrasonic signal. This gain control signal is also delivered to the sensors over a twisted pair of wires (31, 33) by current loop transmission system.

Patent EP-0329174-A3 (EP)
Title: Composite refractory material
IPC: C04B41/51
Filed: 1989-02-17
Abstract: A fibrous substrate having a first coefficient of thermal expansion and having porous characteristics is formed from discrete elements, such as carbon fibers, having anisotropic properties. A matrix formed from a refractory material encases the discrete elements and has a second coefficient of thermal expansion different from the first coefficient. The matrix has minimal chemical or mechanical bonding to the discrete elements to provide for a displacement of the matrix relative to the substrate with mechanical shock or changes in temperature. The matrix includes a first element having refractory properties and selected from the group consisting of hafnium, zirconium, tantalum, tungsten and molybdenum also includes a second element bound to the first element. The matrix is preferably formed by providing a mixture of a first gas containing the refractory element and a second gas containing the second element and by introducing the gases into a chamber containing the substrate. The gases are introduced into the chamber at an elevated temperature and with a pressure pulsating at a particular rate between first and second pressure limits to obtain the deposition of the refractory material on the discrete elements. The gases are periodically exhausted from the chamber and fresh gases are introduced into the chamber. The matrix may consist of first and second layers respectively having hafnium (e.g. hafnium carbide) and zirconium (e.g. zirconium carbide) as the refractory materials. These layers define pores with the substrate and further define an external surface. A layer of rhenium may cover the matrix in the pores and in the external surface.
