Abstract:
The invention firstly relates to a method for the pressing of a press fitting (3), with a tube (2) inserted into the press fitting (3), by means of a pressing tool (1), wherein the press fitting (3) has an encircling bead (31) in which an O-sealing ring (32) is placed, wherein the tube (2) ends within the press fitting (3) and a first pressing is carried out within the bead (31), wherein, furthermore, a further pressing is carried out on the tube-insert side of the press fitting (3) at a distance from the bead, the further pressing leading to press fitting (3) and tube (2) obtaining a conicity which prevents them being pulled off and runs in the same direction. Furthermore, the invention relates to a pressing tool (1) suitable for carrying out the method. In order to further improve a method of the type under discussion, in particular for simplifying the handling over the course of the pressing operation, and in order to improve a pressing tool of the type under discussion, in particular in terms of handling while maintaining the functional reliability of the press connection winch is to be produced, it is proposed, in terms of the method, that the head (31) is widened axially over the course of the pressing operation by being acted upon radially from the outside. In terms of the object, it is provided that the first pressing geometry (21), which is assigned to the bead (31), leaves the bead (31) space at least in one direction for the axial widening of the bead (31).
Abstract:
Techniques are provided for displaying a route symbol with narrative driving directions. A route symbol for a particular maneuver may be used to represent the road to which the maneuver relates. For example, one type of a route symbol that may be used to represent a road may be an interstate route symbol that has substantially the same appearance (e.g., substantially the same or similar shape, and/or substantially the same coloration) as an interstate route sign used to mark the interstate itself. Another example of a type of a route symbol that represents a road is an highway route symbol that looks substantially the same as a highway route sign used to mark a state highway. A route symbol used for the display of a maneuver also may include route symbols that are related to the type of maneuver, such as the type of a turn, described by the maneuver.
Abstract:
The invention relates to an artificial stone floor element with a basic shape that corresponds to the combination of a plurality of square basic elements, especially to an angular floor element. The floor element includes projections and recesses along its peripheral sides of the basic element when seen from the centre of the respective top face of the basic element is substantially point-symmetric with respect to its mid-point. The floor element in further embodiments includes a profile that consists of three projections and three recesses.
Abstract:
Methods and apparatus are disclosed for leak testing the ventilation system of an environmental enclosure using a gas that is naturally present in ambient air, such as nitrogen, oxygen, argon, or carbon dioxide, as a tracer gas. In one embodiment, a gas filter capable of filtering all of the tracer gas from the air flowing through the filter is installed in the ventilation system. Testing is performed by operating the ventilation system to cause outside air to flow through the filter and into the enclosure so as to establish positive pressurization inside the enclosure. A gas monitor placed inside the enclosure is used to detect for the presence of leaks in the ventilation system by monitoring the concentration of the tracer gas inside the enclosure.
Abstract:
A palisade comprises visible or wall surfaces disposed on opposing sides and intermediate end faces. One of the end faces is provided with a projecting convex head, while the other end face comprises a correspondingly formed concave receptacle for the head. When forming a palisade wall, the head of a palisade can engage in the receptacle of a neighboring palisade such that the head substantially completely fills the receptacle. To be able to bend neighboring palisades relative to one another over a large angle and to increase the design possibilities of a palisade wall, the head and the receptacle are disposed eccentrically on the respective end face and preferably in the corner region between the end face and the associated visible or wall surface.
Abstract:
There has been disclosed a cast stone (1) for securing traffic areas outdoors, with the stone (1) bearing at least one pair consisting of a protrusion (9) and an adjacent recess (10) substantially matching the form of the protrusion of the adjoining laid stone (1). It is provided that the tip of the protrusion (9) and the bottom (13) of the recess (10) have an integrally moulded layer (12) of material facing away from the associated lateral face (3, 4).
Abstract:
An anchoring of outdoor traffic areas provided with cobblestones or paving stones made of a plastic or natural stone material is cited, in which the stones are laid in a bed of sand and/or grit. The anchoring method provides for the stones to be further supported by an extensive supporting structure provided with openings and laid on top of the bed.
Abstract:
There is provided an artificial stone for strengthening traffic surfaces in the open, in which the stone, in order to provide wide grooves between adjacently laid stones, is provided on its edge surfaces with integrally formed, completely identical spacer elements, the contacting free end surfaces of the spacer elements having, adjacent one another, a tooth and a recessed contact surface for the tooth of the adjacently laid stone; the tooth-recess sequence, in one peripheral direction of the stone, being the same for all spacer elements; the effective length of the individual edge surfaces of a stone, parallel to the laying plane, being the same as, or a whole-number multiple of, a smallest effective length; each edge surface segment which has the smallest effective length being provided with a spacer element; and the central axes of all spacer elements lying in the middle of the corresponding edge surface segment. The contact surface is formed as a tooth recess corresponding to the size of the tooth and enclosing the latter on both sides in the direction parallel to the laying plane and to the corresponding edge surface. The flanks of thee tooth and of the tooth recess enclose an angle of at least 90 degrees, and the bisector of the angle is essentially parallel to a perpendicular drawn to the corresponding edge surface.
