Patent AT-E6279-T1 (AT)
IPC: E01C23/085
Filed: 1979-08-08
Granted: 1984-03-15
Abstract: Asphalt or concrete pavement is removed from a road bed by an elongated cutter blade (94) that extends in a downward and forward direction along a cutting plane to a cutting edge. The cutting plane forms an acute angle of between 45 DEG and 55 DEG  with the surface of the pavement. The cutter blade is intermittently driven with a force parallel to the cutting plane in the forward direction while the cutting edge penetrates the pavement to drive the cutter blade incrementally in a forward directon and plane off the pavement in a chisel-like manner. A source of vibrations (56) is connected to one end of plural spaced apart resonant beams (54). At the other end, the beams drive the cutter blade. The source produces a reciprocating force that is transmitted to the blade by the beams each of which has an output that reciprocates about a neutral position responsive to the force of the source. A continuous unidirectional force is applied to the source by a tool carrier (44). The blade advances intermittently along a work path through the pavement responsive to the continuous unidirectional force and the reciprocating force. A gap is held between the neutral output position of the beams and the blade when the blade is unable to advance through the pavement responsive to the continuous unidirectional force and the reciprocating force. Specifically, the force of the source is sufficiently large relative to the unidirectional force to overcome the latter, and to drive the tool holder back away from the blade when the blade is unable to advance along the work path, thereby establishing a protective gap. Cessation of resonance is prevented when the blade encounters an immovable object by establishing the protective gap in the described manner.

Abstract: A booth forming a spraying chamber for workpieces to be coated with powder particles has a substantially fully open front side, giving access to an electrostatic spray gun, and a substantially fully open rear side adjoining a housing of a detachable powder-collecting unit which is open toward the chamber while being separated therefrom by an apertured screen. Tubular filter elements in the housing of the powder-collecting unit, having air-permeable peripheral surfaces, communicate with the suction end of a blower in an overlying clean-air unit, thereby giving rise to an air stream which passes generally horizontally through the chamber from its front side to its rear side and entrains particles discharged by the spray gun. Particles bypassing the workpiece to be coated may traverse the apertured screen and cling to the surfaces of the filter elements from which they may be intermittently dislodged by an air blast directed into these elements from the clean-air unit. The dislodged particles fall into a recovery compartment of the housing which lies below the level of the chamber bottom, this bottom sloping down toward the recovery compartment whereby particles dropping to the chamber floor can slide directly into that compartment underneath the apertured screen. A flexible conduit connects the recovery compartment with the spray gun for recirculation of the particles which, after passing through a strainer, are reconditioned by a fluidized bed in the recovery compartment. Cutouts in the sidewalls and a slot in the roof of the booth enable the introduction and withdrawal of workpieces suspended from above.

Abstract: Ventilating unit comprising a housing to the front of which is fitted, preferably pivotably, a cover-flap. The front of the housing comprises a wall that closes off the interior in which a fan is arranged. Known ventilating units of this kind contain, inside, a plurality of components, more particularly a fan, insulating material, an actuator, etc. These components have hitherto been secured to the housing, and to each other, by means of screws or other attachment-elements, resulting in relatively high material and assembly costs. Furthermore, cleaning of the ventilating ducts, involving opening-up the unit, has been possible only by using trained personnel. In order to overcome this problem it is therefore suggested that the wall be built as an inspection-flap which is hinged to the front edge of the housing and is provided with means for locking it to the housing. In this connection the fan housing is designed, or bears against the said inspection-flap, in such a manner that when the latter is locked, the fan-housing is also locked in the housing. Finally, at least one retaining wall is preferably provided inside and this, together with the inspection-flap, produces a ventilating unit with adequate stability.

Abstract: Methods and apparatus for feeding and continuously casting molten metal (1) are described in which inert gas is applied to the moving mold surfaces and to the entering metal for the protection or shrouding of the molten metal surface within the mold cavity from oxygen and other detrimental atmospheric gases. The shrouding is by means of inert gas injected into the mold through a semi-sealing nosepiece (7), or directed at the mold cavity and passing through the necessary slight gaps around the nosepiece. At the same time, such inert gas is further circulated by channeling or shielding the circulated gas for blanketing and diffusing of the inert gas along the moving mold surfaces (9, 10) for cleansing them of undesired accompanying gases, such as atmospheric oxygen, water vapor, sulphur dioxide, carbonic acid gas, etc. as the mold surfaces approach the nosepiece before entering the mold region. In installations where the inert gas is directed at the mold cavity from above and/or below the nosepiece, the gas is ejected at a relatively slow flow rate so as to be noiselessly ejected, i.e. without audible disturbance, the objective being to avoid entrainment of air. Heavier-than-air inert gas may advantageously be used above the nosepiece, while lighter-than-air inert gas is simultaneously used below it.

Abstract: A skin-contacting lubricating layer formed from a hydrogel polymer bonded to a rubber article (such as a surgeon's glove) is treated by means of surfactant material (such as a bactericidal cationic surfactant which preferably has a 6-18C alkyl or alkenyl group, such as an N-hexadecyl group) or a long chain fatty amine so as to substantially improve the lubricity of the layer with respect to damp skin. The hydrogel polymer is preferably a copolymer of 2-hydroxyethylmethacrylate (HEMA) with methacrylic acid (MAA) or with 2-ethylhexyl acrylate (EHA) or with both MAA and EHA. Such a hydrogel polymer has improved lubricity to dry skin and, if used for this purpose, need not be treated with a surfactant or fatty amine to improve the lubricity with respect to damp skin.
