Abstract: A meshing-screw compressor, or expander, comprises twin screw-rotors, or "spindles", (1a,b; 2a,b) each rotor having a helical slot (9) in each half thereof whose cross-section decreases toward the rotor center. The sides of the slot (9) are constituted by stepped flats (16) standing perpendicular to the rotor axes. Each rotor may thus be formed by a stack of laminae, or "disks", on a shaft 4 (as indicated in the right-hand half of Fig. 1). Channels 12, 14 for low and high pressure working-fluid may be disposed in the casing 7 as shown. <IMAGE>

Abstract: The invention is a system for remote control of remotely located substations within a power station distribution area in order to more quickly be able to trace faults and thereby shorten interruptions in electrical distribution. The system uses a central station (1) for remote operation, several link stations (3) connected to the central station via trunk connections (2) and several subsidiary stations (4) per link station for remote operation. The remotely located substations (6) receive information from their central station (5) via the remote operation's radio channel and information from the substation to the central station (5) is transmitted on the section between the substation and the remote operation's link station (3) via a separate radio channel. The link station is therefore equipped with an extra receiver (8) for this radio channel.<IMAGE>

Abstract: In a drill chuck for securing the shank of a tool in a hand-held device, clamping jaws are mounted in a chuck member and bear radially outwardly against the conically shaped surface in a first sleeve into which the tool shank is inserted. A second sleeve is connected to the first sleeve and is threaded engagement with the chuck member. A locking or third sleeve is located about the first and second sleeves. The third sleeve is axially displaceable between a first position and a second position. In the first position the third sleeve engages the first and second sleeves so that the second sleeve cannot be rotated relative to the first sleeve or the chuck member and the tool shank can be locked by the clamping jaws. When the third sleeve is displaced into the second position, the second sleeve is released and can be rotated relative to the chuck member for axially displacing the first sleeve relative to the chuck member and adjusting the radial position of the clamping jaws.

Abstract: A method for cooling rolled stock downstream of a given roll pair of a rolling mill having connected thereto a stock cooling section comprising at least one cooling tube (2), a liquid-coolant jacket (3) surrounding the tube, an external guide tube (8) leading from a given roll pair to the at least one cooling tube (2), and an internal guide tube (4) located in the cooling tube. The method comprises the steps of forcing the liquid coolant from the jacket into the external guide tube (8) in countercurrent with the direction of stock movement and into the internal guide tube (4) concurrently with said stock movement. In accordance with the novel features of the invention, immediately the stock leaves the nip of the given roll pair it is passed into the external guide tube (8) of a first cooling tube in line, this guide tube being placedin direct connection with said roll nip. The arrangement is such that liquid coolant can be forced from the jacket (3) into the external guide tube (8) in a controlled manner and from there into the roll nip while, at the same time, forcing liquid coolant from the jacket (3) in a controlled manner into the internal guide tube (4).
