    • There is disclosed a method of manufacturing a tactile ground surface indicator which comprises a head configured to lie fixed over a ground surface, the method comprising plastically deforming a section of metal plate to form a dish shaped piece and machining an exterior of the dish-shaped piece whereby an external profile of said head is formed. There is also disclosed a method of manufacturing a tactile ground surface indicator having a head and a downwardly projecting member connected to the head to be fixedly receivable by a cavity formed through the ground surface for anchoring the head over a ground surface, in which method an element defining the downwardly projecting member or from which that member is derived is positioned such that an end portion thereof extends through an opening formed through either the head or a piece from which is derived an exterior portion of the head arranged to be visibly exposed when the head is anchored, and plastic deformation of the end portion and/or piece is effected to create an interlock between the piece and element.

    • A seal is disclosed for an opening (3) between a movable object (4) and a road surface (5), and for sealing between the road surface (5) and an apparatus 6 below or level with the road surface (5). The seal may comprise a first seal (1) with a first elasticity and a second seal (2) with a second elasticity. The first and the second seals (1) and (2) are covering the opening (3), the first elasticity is greater than the second elasticity, the first seal (1) is arranged towards the road surface (5) while the second seal (2) is arranged towards the apparatus (6), and the first seal (1) is configured to be subjected to road surface wear. A method of using the seal for avoiding contaminating the apparatus may comprise maintaining the seal by changing the first seal (1) while the second seal (2) is in place.
    • 公开了用于可移动物体(4)和路面(5)之间的开口(3)并且用于在路面(5)与路面(5)下方或与其平齐的装置6之间进行密封的密封件。 密封件可以包括具有第一弹性的第一密封件(1)和具有第二弹性的第二密封件(2)。 第一和第二密封件(1)和(2)覆盖开口(3),第一弹性大于第二弹性,第一密封件(1)朝向路面(5)布置,而第二密封件 (2)朝向所述设备(6)布置,并且所述第一密封件(1)构造成经受路面磨损。 使用密封件以避免污染设备的方法可包括通过在第二密封件(2)就位的同时改变第一密封件(1)来维持密封件。
