Abstract: A transmission circuit (Tx) and a reception circuit (Rx) are connected to a two-wire transmission line (Tl) with full-duplex operating capacity via a hybrid circuit (Hy) in a connection circuit for at least one terminal (Te) which transmits and receives binary signals. The reception circuit (Rx) is also connected via an echo cancellation circuit (Ecc, Add) to the transmission circuit (Tx). A clock generator (PLL, Cr), synchronised by clock pulses supplied from the terminal (TE), is used to control the timing of the transmission circuit (Tx). The synchronisation of the clock generator (PLL, Cr) is activated only if the transmission circuit (Tx) has transmitted a zero level during a specified number of consecutive "0" bits. Synchronisation is not activated if pulses occur with a specified amplitude, characterising "1" bits. <IMAGE>

Abstract: To avoid considerable vertical and horizontal flows in the settler formed by gas collection hoods, of the upflow anaerobic sludge blanket (U.A.S.B.) reactor, each gas collection hood (3) debouches at one or two ends into a gas collection chamber (8) via one or more openings (19), the upper boundary of said openings being situated below the inside surface of the projection or the top of the hood (3) concerned. The gas collection hoods are situated immediately below the level of the effluent discharge and the depth of the settler is shallow. As a result of the decrease in pressure only a few gas bubbles are consequently liberated and the settling of the sludge is not appreciably disturbed.

Abstract: Process and device for cooling a tubular sleeve produced by hot extrusion-blowing of a thermoplastic material through an annular die. In the process, a stream of primary air is flowed under pressure substantially parallel to and spaced from the tubular sleeve and reaches the tubular sleeve at a second stage. The stream of primary air induces a stream of secondary air which flows substantially parallel and proximate to the tubular sleeve at a first stage and whose flow is substantially laminar over most of its path. The device includes a first cylindrical sleeve member that, in combination with the tubular sleeve, defines a secondary air flow space. A second cyclindrical sleeve member and the first sleeve member define a primary air flow space therebetween. A cylindrical ring disposed proximate to the annular die directs air into the secondary air flow space. A source of pressurized air is in flow communication with the primary air flow space.

The slow conduit sections being, at a specified position of the slide in the filter housing internally in flow connection via, in each case, a port, with the outlet conduit in the filter housing and, externally via the filter plates, with the inlet conduit or with a backflow conduit in the filter housing.

Abstract: Disclosed is a process for improving the solids distribution in a circulating fluidized bed system. In the invention, hot ash from the system and fresh carbonaceous fuel are mixed in a chamber which is fluidized so as to form a fluidization zone wherein the heavier material is concentrated and a second fluidization zone which consists predominantly of fines at least a portion of which is separated from the heavier material. This zone separation is facilitated in part by maintaining different gas-mass flow rates so as to form a plug of heavier material. At least a portion of the fine material is then transferred into the reactor while the coarse material is further processed.

Abstract: When polymerizing 1-butene either alone or together with minor quantities of (below about 10%)of other unsaturated monomers, a Ziegler-Natta- composition may be used as high-yield-catalyst, in which, by means of a combination of a solid tetravalent Ti compound supported on MgCl2, an organic Al compound and possible electron donors, liquid hydrocarbon containing 5 to 12 C atoms has been prepolymerized. With this prepolymerized catalyst composition 1-butene may be polymerized particularly in a gas phase. The catalyst composition obtained and the final 1-butene polymer are highly crystalline and do not adhere to each other, and are thus easy to handle and most fluid. The mechanical properties of the product polymer, such as hardness, elastic modulus, tensile strength, yield point, impact strength, etc., are high, and the optical properties, such as light transmission, are equally good.

Abstract: When sanding for instance panelled doors in a belt sanding machine it must be prevented that transversely extending parts (16) are sanded since it would be harmful to sand across the direction of the veins of the wood. A machine according to the invention is therefore provided with a combined sensing and control device which in a simple and effective manner will prevent damage caused by the sanding process by controlling the contact of the sanding belt with the workpiece. The device consists of a disc (14, 20) which is mounted on the sanding equipment. The disc (14, 20) protrudes a distance beyond the sanding position of the sanding belt (15), in order that the disc will sense the workpiece when this is moved under the sanding belt. When the disc (14, 20) rolls across a frame piece (16) the sanding belt (15) is pivoted up above the wood, and when the disc (14, 20) meets a sunken part (18), the sanding belt (15) is pivoted to a non-sanding position.

The corner guide, for guiding an optical fibre (7) or the like around a corner (9) whose radius of curvature is less than a permissible minimum radius of curvature Rp for the fibre (7), guides the fibers (7) by means of the duct (6) along a path which extends into three dimensions. At the corner at the hinge between the panels (1, 2), the duct (6) passes through an "x-y" plane containing the corner at an angle for instance of 70 DEG . This enables an arrangement wherein the projection of the duct (6) onto the "x-y" plane includes a bend whose radius of curvature is less than Rp although the path itself does not include such a bend. The invention finds particular application in optical fibre installations in homes or offices, wherever a fibre has to turn a corner, for instance at the corner of a room. Alternatively it finds application in equipment served by optical fibers which include for instance a hinged panel to which the fibers must extend.

Abstract: In electrical devices connected to high-voltage, especially machine and mains transformers, components (3, 5) for the electrical and mechanical connection of the end of a feedthrough conductor bolt (3) to a connecting conductor (12) carrying high-voltage are often arranged in a chalice-shaped screen (4). According to the invention, in order to damp high-frequency switching oscillations a low-inductance fixed resistor (9), forming the end of the connecting conductor (12), is spatially and electrically arranged between the chalice-shaped screen (4) and a chalice-shaped screening pot (10) similar to said screen, an iron-free choke winding (8) carrying the load current being provided electrically in parallel with, and spatially coaxially with respect to, the fixed resistor (9), which choke winding (8) grips the screening pot (10) with its one end and the screen (4) with its other end. The combination of a high-voltage feedthrough (2) with a damping element for oscillations in the MHz range is especially expedient in cases in which a 400 kV transformer is directly coupled to an SF6 switching device. <IMAGE>
