Abstract: A three-way or multi-way valve (1) is provided, which is built up of a plurality of two-way valves (11-14), each of which has a high pressure connection and a low pressure connection which are separated from each other by means of a valve seat with which a closure element co-operates, the two-way valves (11-14) being arranged to be operated in pairs or in groups by means of a control pressure fluid by way of a control pressure line (40a, 40b) opening into a pressure chamber (35a, 35b, 36a, 36b), and one of the two-way valves (pump valve 11, 12) of each group being arranged in a connection between a pressure source (6) and a load (2), and another two-way valve (tank valve 13, 14) of the same groups being arranged in a connection between the load (2) and a pressure sink (7). With a valve of this type, it is desired to obtain improved closing behaviour with simple construction. For this purpose, at least one of the connections, especially the high pressure connection, of at least one valve (11, 14; 12, 13) of each group communicates with the control pressure line (40a, 40b) by way of a throttle channel (33a, 33b, 34a, 34b).

Title: Non-destructive ultrasonic testing method
Inventor: BERNUS LUDWIG VON DR
IPC: G01N29/24
Filed: 1995-03-31
Abstract: A workpiece, e.g. a welding joint, is tested using a first electromagnetic ultrasound transducer in a first position coupled to the workpiece. The transducer generates ultrasound waves which are spread out in the workpiece. The spread waves are received by a second ultrasonic transducer coupled to the workpiece at a second position. The two transducer positions are independent of each other. Flaws in the workpiece reflect ultrasound waves which are received by the second transducer which generates a signal indicting the presence of a flaw.

Patent DE-19603310-A1 (DE)
Inventor: POHL FRITZ DIPL PHYS
IPC: H01H1/00
Filed: 1996-01-31
Abstract: In order to establish the residual useful life of earth contacts, it has already been proposed to determine the so-called contact action at the breaker gap as a criterion for replacement in the event of contact erosion and to measure the change in contact action during the switching off stage in order to determine the erosion of the contact tips and convert it into the residual useful life. To that end, with a magnetic drive comprising an armature with magnet coils and an associated yoke, the time taken for the armature to move from the beginning of its movement to the point when the contact starts to open is measured. According to the invention, the measured value of the time signal (tk) of the contact opening is determined on the load side of the monitored switchgear, and the measured value of the time signal (tA) is determined by a de-energized signal emitted at the beginning of the armature movement. Intended in particular for use in three-phase systems, the switching voltage is measured as a change in voltage at an artificial neutral point. The associated arrangement comprises a de-energized signal line (20) disposed between the switchgear (1) and an evaluation device (100, 200, 300).

Filed: 1996-04-17
Abstract: Opto-electronic approach sensor (7,9) has a control circuit (3), a sensor assembly (2a) and a receiver assembly (2b). Typically the sender is an LED (7) which controls a receiver (10), which is part of the receiver assembly.

Title: Bucket for cleaning purposes
Inventor: GMEILBAUER ENGELBERT
IPC: A47L13/58
Filed: 1996-06-24
Abstract: The insert plate (8-10) is stood in the bottom of the bucket to form a raised surface over a hollow space in which dirt and debris collects. Movement of the cleaning equipment e.g. cleaning mops, does not disturb the dirt layer and thus keeps the cleaning fluid clean. The surface can be formed by a perforated plate, or by a grid, supported in the bottom of the bucket by at least three feet. Alternately the support surface can be formed by placing several grids over each other. This forms a collecting space between the dividers of the grids. The grids have sloping edge profiles adapted to fit into the outline of the bucket.
