Abstract: To automate the operation of coupling and uncoupling a suction pipe for pumpable media, especially for liquid manure, on the filler neck of a movable tanker, there is proposed a device comprising a suction-pipe holding device, in which a suction pipe (1) is suspended so as to be displaceable from a specific neutral position. A receiving and guiding device (11), having at least one pivoting arm and a pivot axis which is arranged in a fixed position relative to the filler neck (15), is moved upwards by means of an adjusting member (12), at the same time receiving the suspended suction pipe and guiding it up to the filler neck. This operation is started by switching an actuating device. Further functional elements, such as, for example, a filler-neck cap (15), a vent valve and the like, are actuated as a function of the working state of the device via a control device (14) connected to the adjusting member. An operation which is to be repeated frequently is automated by means of the device according to the invention. <IMAGE>

Abstract: The invention concerns an instrument to measure the tension of yarns - particularly weft yarns (f) which wind or unwind forming a "balloon" - avoiding further deviations thereof, which makes use of a variable impedance, for example a differential capacitor or a variable inductor, comprising a movable component (1) and at least one fixed component (2,3) as parts of an electric measuring circuit. All the components (1,2,3) of said instrument have a centred symmetry and a passage (2A,3A,3B) through their centre for the yarn (f) whose tension has to be measured, with a yarn guiding and deviating eyelet (6) positioned in correspondence of the closing vertex of the "balloon" and fixed to the movable component (1) of said variable impedance. The variable voltage detected on one of the components of said impedance, in function of the tension of the yarn sliding through said eyelet (6), is measured by a measuring device connected to said movable component. 
     The invention also concerns a weft yarn feeder for looms, having at its outlet an instrument with centred symmetry as described hereabove, positioned on the main axis of the weft feeder so as to measure the tension of the unwinding yarn being fed to the loom.

Abstract: In a membrane pump (1), its membrane (21) is formed from two membrane discs (22, 23) which are arranged at an axial distance from one another and enclose an internal space (24), and whose size can be altered in the event of damage to one of the membrane discs (22, 23). Furthermore, arranged in the membrane disc (22) facing the conveyance chamber (7) are a signal transmitter (31) and, in the pump housing (2), a signal receiver (32) which is connected to a device (34) for electronic evaluation and amplification of the signals emitted by the signal receiver (32). As a result of this design it is possible to identify any damage to the membrane (21) in good time and hence reliably to prevent the hydraulic medium entering the conveyance medium. <IMAGE>

Abstract: It is specified with regard to a measuring device for work pieces with rotational symmetry, which has an adjustable clamping device that supports the work piece, and a movable measuring carriage which supports at least one measuring head that measures the work piece by means of a feeler in the radial and/or axial direction, how to avoid the disadvantage that when there is a change in the measurement task it is necessary to change over in a complicated fashion to a different feeler, which is adapted to the new measurement task. For this purpose, the measuring head is equipped with a feeler support which bears a plurality of feelers and is rotatable. Thus, the feelers can be rapidly rotated into the measurement position, where they are fixed by a locking device.

Abstract: In response to a request from an input/output module, a contiguous valid data area is identified in a data block completely transferred into the buffer memory (BUF) of a controller (CU). The identification is effected by control information (ZPAR, AD), likewise transferred to the controller (CU) from the requesting input/output module together with the respective data block. In the controller (CU), the transferred data block is subdivided into individual sub-blocks, each having the same number of data units, and the number of sub-blocks taken up by the valid data area is determined on the basis of the provided control information (ZPAR, AD). Subsequently, only the taken-up sub-blocks are transferred, together with selection information (BS) respectively derived from the control information (ZPAR, AD) for the individual data units of the respective sub-block, one after the other to the main memory. <IMAGE>

Abstract: With reference to Figure 1, a rotary lobe pump 1 for pumping blood plasma comprises a casing 2 and a pair of inter-engaging lobe rotors 3, 4 mounted for contra-rotation within the casing 2 about substantially parallel axes 5, 6. 
     Substantially parallel shafts 7, 8, of hollow form, also mounted for rotation about the axes 5, 6 are connected to the rotors 3, 4. The hollow shaft 7 locates a tie rod in the form of a draw bolt 10 which extends through the shaft so as to secure it to the rotor 3, and the hollow shaft 8 similarly locates a tie rod in the form of a draw bolt 16 which extends through the shaft so as to secure it to the rotor 4. 
     The draw bolts 10, 16 are close-fits within their associated shafts 7, 8 so as to prevent radial contact between the casing 2 and the rotors 3, 4. Between the ends of the draw bolts 10, 16, remote from the rotors 3, 4 and clamping/retaining nuts 17, 18, are disposed part-spherical washers 37, 38. Resilience in the clamped washers 37, 38 causes tensile loads to be applied to the draw bolts 10, 16. 
     The shaft 7 is a drive shaft and is driven by an electric motor (not shown) by way of a drive key 19.

Abstract: An anchor bolt has a fastening sleeve (8), an expansion sleeve (5), an expansion body (2) and a spring member (7) interposed between the fastening sleeve (8) and the expansion sleeve (5). The expansion body (2) is disposed at one end portion of a threaded rod (1) formed as an anchor main body and is to be inserted deep in a hole (12) of a concrete structure together with the threaded rod (1). The fastening sleeve (8) and the spring member (7) are loosely fitted on the threaded rod (1) and, when the fastening sleeve (8) is forced into an inlet portion (12 b ) of the hole (12), it compresses the spring member (7) to urge the expansion sleeve (5) onto the expansion body (2) so as to be expanded thereby, thus preventing the anchor bolt from being removed from or being loosened in the hole. The fastening sleeve (8) preferably includes an opening (9) through which an end portion (7 b ) of the spring member (7) extends to be exposed for visual inspection. The expansion body (2) may either be formed integral with the threaded rod (1) or be formed as a nut mating therewith.

Abstract: An underwater vacuum cleaner (10) for cleaning debris from the bottom of a pool has a collection chamber (12) formed with an inlet (14), an exhaust port (16) and an actuator port (18). Operatively associated with the actuator port (18) is a reciprocable push button (80) which moves between a seated position wherein the actuator port (18) is closed, and an unseated position wherein the actuator port (18) is opened. With the push button (80) in the seated position, an air lock is created in the collection chamber (12) when the chamber (12) is submerged into the pool. Once the collection chamber (12) is submerged, movement of the push button (80) into its unseated position breaks the air lock and allows water, and debris carried by the water, to enter the collection chamber (12). The collection chamber (12) is emptied of water for subsequent use, and the collected debris is held trapped in the chamber (12), by withdrawing the collection chamber (12) from the pool. Specifically, upon withdrawal of the collection chamber (12) from the pool, the push button (80) is pulled into an unseated position by the water draining from the collection chamber through the filtered exhaust port.
