Abstract: A rotary trench cutting or rock milling saw unit (12) is supported on a head (18) for movement about two mutually perpendicular axes (50,62). The head is adapted for pivotal mounting on a backhoe boom (20) or similar positioning structure. Rotary rock cutting wheels are driven by a hydraulic motor and a support vehicle (24) for the saw unit includes a hydrostatic drive system with a variable displacement hydraulic pump driving variable displacement track drive motors which may be set in a slow speed operating mode for trench cutting operations or a high speed mode for tramming between work sites. A constant rate of power input to the saw unit is maintained by sensing saw drive motor supply pressure and adjusting tract drive motor supply pump displace­ment to maintain a constant feed or rock cutting rate. The apparatus includes hydraulically operated actuators for rotating the saw unit and its support boom about a vertical axis (40) with respect to the apparatus undercarriage, elevating the boom with respect to the undercarriage, and moving the saw unit about three mutually perpen­dicular axes (40,50,62) with respect to the support boom. Each of the actuators includes a control valve which may be selectively positioned to operate the actuators in reverse directions, lock the actuators in a predetermined position, or permit the actuators to oscillate or rotate the saw unit with respect to the various positioning axes of rotation when the saw unit is confined in a trench.

Abstract: An roll-over valve includes a hollow valve housing (12), a valve member (32) in the valve housing, and a base (66) for retaining the valve member in the valve housing. A ball (34) is provided for moving the valve member within the valve housing. The valve member is positioned within the hollow valve housing for movement generally along a longitudinal axis (50) between an outlet-opening and -closing position. The valve member includes a ball-receiving cup (40) configured to define a first inclined ramp portion (46). The base retains the valve member within the housing and includes a second inclined ramp portion (76). The base is coupled to the valve housing to present the first and second inclined ramp portions in opposing spaced-apart relation to define a ball-receiving space therebetween. The ball is positioned in the ball-receiving space in substantially camming relation to each of the opposing first and second inclined ramp portions. The ball rides on both ramp portions to move the valve member to its outlet-closing position in response to tilting the valve housing about its longitudinal axis during a vehicle rollover and during abrupt changes to vehicle motion.

Abstract: The door hinge is mainly intended for spacecraft and more particularly for space shuttles. The hinge is compact and has a simple mechanism consisting of two struts, three pivots and corresponding supports. The whole assembly is placed inside the vessel, i.e. in a protected position. During a manoeuvre in which the door is opened, the hinge pivots around an axis situated outside the wall of the vessel, and this allows for large opening angles. The installation also comprises secure locking devices preventing the door from opening and also providing for the transmission of forces from the door to the vessel, forces which exist when its internal pressure is higher than that outside. Finally, the hinges and the locks may be motor-driven to allow remote control of the opening and closing of the door. <IMAGE>

Abstract: The invention relates to an elastic street pavement mass compri­sing aggregate bound by a binder and, when needed, colouring agents and other additives, and which is particularly suitable for preparing pavements having the shade of the aggregate or being toned. The efforts made so far to replace bitumen, which is hard to dye, by a colourless binder, have resulted in the use of ex­pensive and brittle binders. However, an economical, strong and dyeable pavement mass has now been discovered, the binder of which consists of tall oil resin, wood resin, turpentine resin, their derivatives or a mixture formed by these agents, and of a process oil softening the above resins, comprising additionally rubber and plastic as auxiliary agents. The products have a better stability and at least as high an abrasion resistance to studded tyres as a conventional bitumenous pavement mass.

Abstract: In an ISDN system comprising a plurality of DSLs each having a plurality of DTEs and an ISDN switch having a TEI list, a multiplexer (37) is used for enabling each DTE to access the ISDN switch (21) through a single primary rate DTL (27) in the time division technique. The multiplexer (37) comprises subscriber interfaces (38) connected to DSLs, respectively. The subscriber interface (38) has first TEIs assigned to DTEs on the corresponding DSL and has a first data link with each DTE on the basic interference D channel using a first LAPD frame signal with the first TEIs. The subscriber interface has a second TEI assigned thereto and registered in the TEI list in the ISDN switch. The subscriber interface derives information field from the first LAPD signal and forms a second LAPD frame signal having the second TEI and the derived information. The multiplexer (37) statistically multiplexes a plurality of second LAPD signals from subscriber interfaces into the D channel on the DTL to form a second data link between each subscriber interface and the ISDN switch so that load of the ISDN switch is reduced. Addition of a switch selection code to the second TEI enables to switch the multiplexer to another ISDN by use of a cross-connector on the DTL. Use of line selecting signal in DTE signal also enables the multiplexer to transmit the DTE signals onto a different private line.
