Patent AT-E77155-T1 (AT)
Inventor: BROOKS PETER LEONARD
IPC: G01R31/08

Abstract: Method and apparatus for detecting and obtaining information about (particularly locating) an event (E) i.e. a change in a variable, for example a liquid leak. In a preferred embodiment, two conductors (11,12) follow an elongate path and are connected to each other through a power source, preferably a constant current source (15). In the absence of an event, the two conductors (11,12) are electrically insulated from each other at all points along the path. When an event (E) occurs, the two conductors (11,12) become electrically connected at a connection point at which the event occurs, thus completig a test circuit in which a current of known size then flows. When using a constant current source (15), the size of the current does not depend on the resistance of the connection. One of the conductors is a locating member having known impedance characteristics along its length, and by measuring the voltage drop between the connection point and one end of the locating member, the location of the event can be calculated. The voltage drop can conveniently be measured by means of a third conductor which connects, via a high impedance voltmeter (14), the ends of the locating member.

Abstract: A canned motor pump wherein the can has at least two coaxial tubular walls defining an annular space for the flow of a preferably gaseous fluid which is used to facilitate detection of leaks in the walls of the can. Each tubular wall can individually seal the driving unit from the driven unit of the pump motor. The leak detector can generate visible, audible and/or otherwise detectable signals, and such signals can also serve to stop the motor in the event of leakage.

Abstract: A sanitary outlet fitting contains an opposing pressure element (22) between a mixing valve and an outlet (14). The said element (22) has an element which can be deformed or moved under the pressure of the water released by the valve, which builds up an opposing pressure. The build-up of the opposing pressure reduces the pressure drop at the output of the mixing valve and thus the amount of noise produced.

Abstract: A hydraulic actuator assembly for use in a mold clamping unit of an injection molding machine. The actuator assembly serves as a rapid-travel drive for mold opening and closing movements and as a source of elevated mold clamping pressure. Among the hydraulic elements contributing to the operation of the mold clamping unit are a power piston for effecting elevated mold clamping pressures and a drive piston for effecting rapid die closing movements. With the hydraulic actuator system of the present invention, it is possible to control the operation of the mold clamping unit based on two-sided hydraulic influencing of the power piston and the drive piston.

Abstract: The invention relates to the connection of two running gears with multiple axles to a group of running gears for railway vehicles with low-lying loading bridge (10), the running gears having at least two wheel sets (4) of small wheel base and a running gear frame, comprising side cheeks (1) and transverse beams (2) between two axles in each case, the wheel sets (4), being fixed in the running gear frame by means of axle bearings (3) and each running gear being connected to the loading bridge without king pins, merely by means of in each case a laminated bearing spring (6), lying longitudinally at the side in front of each side cheek (1), and a link suspension. The object of the invention was to combine running gears of the type mentioned at the beginning into groups of running gears and to arrange them underneath the vehicle frame or the loading bridge (10) in such a way that the exact turning angle of each running gear and of each group of running gears when travelling around a bend is ensured without enforcement and that an exact axle load balancing of the running gears of each group of running gears is ensured. This object is achieved by the running gears of each group of running gears being connected to one another by a connecting beam arranged in the longitudinal centre of the running gears and mounted on them in a jointed manner, the connecting beam (13) being arranged centrally with play between guide brackets (14) of the loading bridge (10). In this arrangement, the facing ends of each laminated bearing spring (6) of the running gears of each group of running gears are connected to each other via their links by a compensating lever, which is mounted on a bracket of the weighing bridge. <IMAGE>

Abstract: An information distribution system provides information to a user, when the information corresponds to criteria individually selected by the user, and then charges the user only for the selected information thus provided. Encrypted information packages (IP's) are provided at the user site, via high and/or low density storage media and/or by broadcast transmission. The IP's selected by the user are decrypted and then printed or displayed for viewing by the user. The charges for the IP's thus displayed are accumulated within the user apparatus and periodically reported by telephone (36) to the system's central accounting facility which issues encryption keys. The encryption keys, used to decrypt the IP's, are changed periodically. If the central accounting facility has not issued a new encryption key for a particular user station, the station is unable to retrieve information from the system when the key is changed.
