Abstract: Abstract A device for transport or displacement of elongated objects in particular, with respect to the device itself, substantially in the longitudinal direction of the object and comprising a rotatable traction wheel  and means for rotating said traction wheel which comprises a pair of juxtaposed, synchronously rotatable cam discs      provi-ded on individual shafts or on a common shaft     , each of said cam discs having on its inside facing the other cam disc a series of preferably arcuately bent cams projecting from their respective disc, each cam extending substantially from the vincinity of the shaft   to the circumference of the disc in such a way that the circumfe-rential end of each cam      is located ahead of the inner end of the same cam as seen in the rotational direction of the disc. To make the device as versatile as possible with respect to its range of utilization and thus to per-mit it to be used in very different fields of the technics, the discs      are movable or adjustable and lockable in relation to each other with respect to their mutual dis-tance and/or position.

Abstract: BURIED ZIRCONIUM LAYER ABSTRACT OF THE DISCLOSURE A nuclear fuel element for use in the core of a nuclear reactor is disclosed and has a composite cladding having a substrate, an unalloyed zirconium barrier metallurgically bonded to the inside surface of the substrate, and an inner layer metallurgically bonded to the inside surface of the zirconium barrier.  In this composite cladding, the inner layer and the zirconium barrier shield the substrate from any impurities or fission products from the nuclear fuel material held within the composite cladding.  The zirconium barrier forms about 1 percent to about 30 percent of the thickness of the cladding.  The inner layer and the zirconium barrier protect the substrate from stress corrosion and the zirconium barrier restricts the propagation of stress cracking.  The substrate and the inner layer of the cladding are selected from conventional cladding material, and preferably are a zirconium alloy.

Abstract: ADAPTIVE SIGNAL RECEIVING   METHOD AND APPARATUS          Abstract A tone receiver suitable for use in a telephone system and which adaptively narrows its amplitude sensitivity range defining valid tone signals on a per call basis in accordance with the amplitude of a first tone signal received on a call.  The signal range adaptability improves signal echo rejection and spurious noise talkoff. A preferred embodiment is implemented by a programmed digital signal processor which increases the lower amplitude signal threshold in accordance with the amplitude of the first signal.  An alternative embodiment adaptively attenuates the level of incoming signals before signal validation.  A further improvement of both embodiments allows further amplitude range narrowing in response to any subsequent signal on a call which has an amplitude greater than that of any preceding signal in the call.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is concerned with a device for uniformly dissolving a solid additive in flowing liquids.  The device of the invention comprises a container forming an open-topped receptacle;  a rigid additive body having a hollow core, the add-live being disposed in the receptacle, an external surface of the additive and an internal surface of the additive to be dissolved away by the flowing liquids;  means for sealable closing the receptacle; means defining a liquid inlet to the receptacle and a liquid outlet from the receptacle;  and a tube providing fluid communication from the liquid inlet to an outlet of the tube near a bottom of the receptacle, outer dimensions of the additive being smaller than inner dimensions of the receptacle and inner dimensions of the additive being larger than outer dimensions of the tube, the receptacle, tube and additive defining inner and outer annular spaces. The additive is positioned in the receptacle such that liquid flows unidirectionally in concentric axial paths toward the liquid outlet through flow paths defined by the annular spaces, one path being defined by the annular space between the tube and the inner surface of the additive and another path being defined by the annular space between the outer surface of the additive and the receptacle. Dissolution of the additive from the inner and outer surfaces remains constant as the inner surface is enlarged and the outer surface is diminished while the additive dissolves.

Abstract: METHOD AND APPARATUS FOR NONSTEADY STATE TESTING                  OF PERMEABILITY     ABSTRACT OF THE DISCLOSURE         The permeability of a core sample is measured during nonsteady state flow of fluid therethrough. A predetermined test pressure is supplied to an upstream end of the core sample while that sample is disposed in a fixed, closed volume and is subjected to a constant, predetermined confining pressure.  The change in pressure across the core sample, with the passage of time, is measured; and the permeability of the core sample is determined as a function of the time-related measure of pressure change.

Abstract: ABSTRACT     A cylindrical elastomeric seal is disclosed for externally sealing a manhole assembly against surface water infiltration between the manhole casting and the Supporting structure and through the supporting structure.  The seal has a first sealing section adapted to receive the edge of the flange of a manhole casting, a second sealing section adapted to be received by the external surface of the manhole chimney or cone, and an intermediate section, joining the two sealing sections, that spans the vertical distance between the casting and the chimney or cone.  Sealing means hold the two sealing sections in place against the casting and chimney or cone, creating watertight seals.  An extension skirt increases the area the seal can cover, allowing the entire supporting structure to be sealed in the case where the chimney height is too great to be spanned by the inter-mediate section of the seal alone.  The seal can be used on old or new construction and does not interfere with normal use of the manhole.

Abstract: HOT CARRIER DETECTION              Abstract of the Disclosure In a local area network for data communications, stations which distributively control their access to a common bus or other medium are able to identify the location of any "hot" station transmit-ter (one stuck continuously in an "on" condition which cannot be isolated from the medium).  Such networks are effectively disabled by a hot carrier, since each station conditions its access on sensing the medium as previously idle.  The present "loop test" method permits all stations in the network to quickly establish the location of a hot trans-mitter, and thereby quickly direct field repair personnel to that location.  It also permits operators to take action to physically disconnect the faulty transmitter from the medium, so that the other stations may continue to use the network until the fault is repaired.
