Abstract: Road safety barrier includes a resistant part and one or two dampening parts for a lateral barrier or a traffic divider respectively. The resistant part of the wall type barrier may be rigidly connected to steel plates which are equally spaced and have been specifically conceived for increasing the resistance during an impact caused by a heavy vehicle. The plates have a slot for the passage of ductile screw anchors, allowing the initial displacement of the resistant part and its connection to the support. If provided, the ductile anchor parts are covered by the dampening part.

Abstract: Light guardrail for bridges formed by a plurality of uprights (1, 2) made of sheet steel and having a box-like shape. The uprights are individually fixed by means of screw anchors (4) to a support (5) made of concrete (Kerbstone of the viaduct or foundation for the lateral edge on an embankment). The uprights (1, 2) are covered by a cover sheet steel (7) formed by a shaped sheet steel having at New Jersey profile, which partially has at form complementary to the profile of the uprights (1, 2). The individual uprights (1, 2) are connected to each other by means of steel pines (26, 27) fixed on the rear side of the uprights.

Abstract: A self-propelled pavement lane apparatus comprising a radial-frequency microwave generator extending across one lane of the roadway having an antenna with a slotted waveguide directed toward the roadway for heating a lane-wide stretch of the roadway. A ripping device is provided behind the microwave generator to rip up pavement which was heated by the microwave generator. A screw conveyor conveys the heated and ripped pavement inwardly toward a central axis of the apparatus where it is fed by a chute to a mixing chamber containing counter-rotating mixing blades. Fresh bituminous binder and/or filler may be added to the mixing chamber to be mixed with the ripped pavement which is then discharged from the mixing chamber by a second screw conveyor, to be distributed across the lane. Following the second screw conveyor is a finished plate for initially compacting the refinished surface.

Abstract: A scanning barrier which can detect and discriminate objects which are within the scanned area. A transmitter on one side of the scanned area transmits a laminar barrage of electromagnetic microwaves across the scanned area. The laminar barrage of electromagnetic microwaves have a thin width and a predetermined height. A receiver across the scanned area receives the microwaves. The receiver is formed of a plurality of vertically adjacent elemental receivers which divide the laminar barrage into a series of horizontal slices. A logic circuit is connected to each of the elemental receivers and can detect the interruption of the laminar barrage to that elemental receiver.
