Abstract: A B S T R A C T Process for the preparation of atmospheric hydrocarbon oil distillates. A residue is separated by C4+ deasphalting into a deasphalted oil, which is catalytically cracked or hydrocracked, and a C4+ asphalt. The C4+ asphalt is catalytically hydrotreated under such conditions that more than 50 %w of the feed is converted into a material which does not precipitate in a C4+ deasphalting process. The hydrotreated product is separated by distillation into one or more atmospheric distillates, a vacuum distillate and a vacuum residue with an initial boiling point above 500°C. The vacuum distillate of the hydrotreated product is converted by catalytic cracking or hydrocracking into one or more atmospheric distillates. At least 50 %w of the vacuum residue of the hydro-treated product is again subjected to the C4+ deasphalting.

Abstract: ABSTRACT OF THE DISCLOSURE A railway track renewal or construction car for use in a track renewal or construction train, which car is in the form of a straight beam resting on its ends on two rail engaging bogies, the front of which is adapted to roll on the old track to be renewed and the rear of which runs on the track which just has been renewed.  Between the bogies, there is provided a device for removing the rails of the old track, means for discarding the old ties, a means for reg-ulating the ballast, a means for laying new ties and a means for closing the new rails previously laid on either side of the track.  In order to permit such a car to operate on a cleared right-of-way where no previous track exists, the car is provided with a telescopic undercarriage which can be lowered onto the ballast of the right of way replacing the front bogie as a front support for the car.  The undercarriage is provided with a suitable rolling device such as an endless track.  The undercarriage may be wider than the track gauge or narrower than the track gauge, and where wider than the track gauge, a runner arrangement may be provided to allow the car to proceed in reverse back from a construction site with the undercarriage supported clear of the rails of the track.

Abstract: TRACK SIGNALLING SYSTEM            ABSTRACT OF THE INVENTION         A track circuit signalling system for an electrified rapid transit system using significantly fewer components is disclosed.  Instead of a transmitter and receiver at each track circuit boundary, alternate boundaries have transmitters only; and the intermediate boundaries have two receivers.  The coupling units for the two receivers are more economical than the prior art coupling unit for coupling the transmitter-receiver combination.  The transmitters on each side of a re-ceiver pair transmit signals on different carrier frequencies.      Each transmitter transmits in both directions from its location.          Of the two receivers at a given boundary, one is tuned to re-spond to signals from the transmitter on one side, while the other receiver of the pair is tuned to respond to signals from the transmitter on the other side.  For special applications using overlapping track circuits, selected transmitters may be omitted and a single receiver used on each side of the omitted transmitter.

Abstract: ABSTRACT OF THE DISCLOSURE:     An apparatus for thermal treatment of the human body, using electromagnetic waves (200 to 2500 Mc/s) and radio-metric means for monitoring and possibly controlling the tempe-rature reached by the living tissues.  A generator at ultrahigh frequency delivers a power of about one Watt into a coaxial cable terminated by a probe emitting electromagnetic waves in the organ to be heated by dielectric losses in the medium.  A multichannel receiver, switched at intervals, analyzes the radiation re-emitted by the living tissues through the probe, then utilized as a receiving antenna.  The temperature reached in a region surrounding the probe is deduced therefrom and can be utilized for controlling the power emitted through a servocontrol system.

Abstract: Abstract of the Disclosure A method and a machine for manufacturing multi-tube filters.  The filter is manufactured from a continuous material web which is folded in zigzag, one layer upon the other, the length of the respective layer corresponding to the desired length of the filter tubes. During the folding of each layer, said layer is joined to the layer below by parallel, lengthwise seams, whereby rows of contiguous filter tubes are formed and neighboring rows of filter tubes are joined together.          The seams that delimit the respective tubes in a row of filter tubes are positioned in alignment with the corresponding seams in all the other rows of filter tubes and the seams that join together neighbouring rows are positioned right between said tube-forming seams. The interconnected layers form, when the filter unit is extended in a direction at right angles to the layers, a filter unit comprising a plurality of tubes that are essentially square in cross-section.

ABSTRACT OF THE DISCLOSURE           Replaceable liner for the discharge assembly of a rotary grinding mill or the like is disclosed, in the preferred embodiment, as including first and second, self-supporting box members.  The first box member includes closed sides, bottom, and second end, and includes an open top and first end.  The second box member includes closed sides, top, and bottom, and includes open ends.  When the grate is removed from the first discharge casting, the second box member can be inserted within the first discharge casting and moved into the second and third discharge castings.  Then the first box member can be placed within the first discharge casting.  Thus, when the grate is attached to the first discharge casting, the first and second box members will be captured within the first and second discharge castings.  Reinforcing members are embedded in the box members for retaining their shape.  Furthermore, the angle between the inside surfaces of the top and sides of the box members is perpendicular to increase the volume of the ground material path and for increasing wear.
