Abstract: A train monitoring and reporting system in which each car of a multi-car train is provided with sensors to monitor brake, door, motor and other functions. A controller in each car sequentially and repetitively reviews the condition of each sensed function and evaluates the conditions to determine whether a fault condition exists. The evaluation result is stored and the review is continued and repeated. The lead car of the train repetitively and sequentially interrogates the storage units in each car for each type of fault condition, stores the responses to the interrogation and displays to the motorman any faults reported. The cars communicate through a multiplex data link system which connects the cars in series in a multiplex current loop. The number of times each fault occurs is counted, the count being then available for readout by maintenance personnel.

Abstract: An underwater riser system in which the primary riser is surrounded by lengths of jacket pipe which form annular buoyancy chambers, there being a pressure fluid supply connected to the buoyancy chambers via valve means including at least a pressure differential valve which controls the amount of water displaced from the chamber by the pressure fluid. Advantageously, the valve means for each chamber also includes remotely controlled means by which the amount of buoyancy provided by the chamber can be varied at will, e.g., from a positive buoyancy to a buoyancy less than the operating weight of the portion of the riser system with which that chamber is associated.

Abstract: An hydraulically operated striking apparatus for driving a rock drill comprises a body having an axial, cylindrical, interior space with an inwardly protruding annular member. A cylindrical piston is positioned in the space in sliding contact with the protruding annular member, and the piston has a canal in its outer surface. The body, the annular member and the piston define two annular spaces and an annular distributing valve is caused to slide within one of the spaces under fluid pressure. The two spaces communicate with each other by means of the piston canal when the piston is in a first slidable position, and the protruding annular member prevents communication between the two spaces when the piston is in a second slidable position. The piston is provided with an axially disposed extension which, in combination with an outlet, serves to permit a third annular axial space to communicate with either an inlet or an outlet at all times.

Abstract: A stroke limiting mechanism is connected with the movable member of a hydraulically operated machine to precisely position the movable member.

Abstract: A cutting tool is mounted on a tool slide which is movable along a workpiece to cut a thread therein or thereon. The tool is shiftable toward and away from the workpiece by a piston and cylinder arrangement having a fixed stroke length. Adjustment of the starting and therefore the ending point of the stroke is accomplished by a differentially threaded assembly which is rotated by a drive motor. Rotation of the threaded assembly produces pulses which are counted and compared with a stored count to start and stop the drive motor. Cycles of operation are also counted and compared with fixed counts, the extent of adjustment in each cycle being related to the number of cycles.

Abstract: Waste wood, such as stumps and snag, is treated to make it suitable for the production of paper pulp, whereby the raw waste wood is initially crushed so that part of the bark, sand and stones attached to the wood is detached at this stage already, the obtained crushed material is fed into a washer tank for further washing away bark, sand, stone and peat material from the wood, high-pressure water nozzles being provided at an inlet end of said washer to impinge strong water jets on the crushed wood material, and flow creating means being provided at the lower part of the washer tank to produce a water flow directed slantedly upwards towards an outlet end of the washer tank in order to entrain heavy wood fragments, which may tend to sink into the material leaving the washer tank at said outlet end thereof, said material being further after-crushed and sieved to separate an accept fraction thereof for feeding to a pulp production process.

Abstract: A flowline is connected remotely to an underwater installation, typically an underwater wellhead, by remote operations carried out from an operational base at the water surface by connecting an end of the flowline to a swivel which has a flow passage coaxial with the axis of rotation of the swivel, guiding the swivel downwardly to a predetermined position at the underwater installation, then remotely connecting the swivel passage to a flow passage of the underwater installation, and then laying out the flowline while allowing the swivel to turn freely, whereby the end of the flowline connected to the swivel is allowed to assume a normal installed position which is not dependent upon a predetermined rotational disposition of the swivel.

Abstract: An amusement device in the form of a novelty disc manipulating device wherein an upstanding housing with transparent side walls has a narrow internal chamber through which a disc can be movably manipulated. A pivotally mounted operating lever is disposed adjacent to the bottom of the housing and includes a projecting portion which can be digitally engaged. A disc, advantageously a coin, is disposed within the chamber and normally rests on edge upon the top of the lever. At one upper corner of the housing, an angularly disposed rebound surface is provided. A support shelf is spaced somewhat beneath the other upper corner of the housing. When the lever is depressed, the disc is propelled upwardly to bounce off the rebound surface, against the top of the housing, and hopefully onto the support shelf. If the disc fails to stay on the support shelf, it gravitationally drops onto the top of the lever and the lever is again operated, until the disc is successfully positioned on the support shelf.
