    • During use, a wheel of a railway vehicle may become out of round, which will be detrimental to both the vehicle suspension and the railway track. The shape of such a wheel may be monitored to detect any such out of roundness, while the wheel is rolling, by measuring how far the flange of the wheel projects below the upper surface of the rail. This may be achieved by mounting a rigid bar (24) alongside the rail (10), the bar (24) being supported resiliently so as to be depressed by a flange of a wheel (40), and by measuring the vertical displacement of the bar. The bar (24) may be supported by a plurality of flat leaf springs (26), which are inclined to the horizontal at for example 30 DEG . This ensures that the bar (24) remains substantially parallel to the top surface of the rail (10) when depressed by the flange of a wheel (40).
    • 在使用过程中,铁路车辆的车轮可能会变圆,这对车辆悬架和铁路轨道都是有害的。 可以通过测量轮的凸缘在轨道的上表面的下方突出多远来监测这种轮的形状,以便在车轮滚动时检测任何这样的圆度。 这可以通过在轨道(10)旁边安装刚性杆(24)来实现,杆(24)被弹性地支撑以被轮(40)的凸缘压下,并且通过测量 酒吧。 杆(24)可以由多个平板弹簧(26)支撑,该平板弹簧(26)在水平方向上倾斜,例如30度。 这确保当由轮(40)的凸缘压下时,杆(24)保持基本上平行于轨道(10)的顶表面。

    • A curve forming device has a first elongated, flexible member (12) with a plurality of equal-length projections (16) extending perpendicularly from one side. The projections have end faces aligned parallel to the first elongated, flexible member. One portion (20) of a hook-and-loop fastener is affixed to the end face of each projection. A second elongaged flexible member has a complementary portion (24) of the hook-and-loop fastener affixed along its entire length. To form a curve, one of the flexible members is pre-shaped into the desired curve. The other flexible member is attached by engaging the hook-and-loop fasteners on the projections to the fasteners on the other flexible member. The curve forming device is then locked in place. Pressure sensitive adhesive can also be employed.

    • A head for the linear dimension checking of mechanical pieces including a casing, an arm carrying a feeler for touching a surface of the mechanical piece to be checked, a fulcrum, coupled to the casing and the arm, for enabling displacements of the arm with respect to the casing and a transducer for providing signals depending on the position of the arm with respect to the casing. The head has specific flexibility and modularity features, thanks to the possibility of operating from the exterior for adjusting and replacing various components. The transducer is of the inductive, half-bridge type, with multiple windings. An integral element for the electric connection to a processing unit includes the windings of the transducer, a cable and a connector, and the latter comprises a rapid locking/unlocking device. The ends of the cable are connected between the windings of the transducer and the connector by means of an over-moulding process of a plastic material. A checking apparatus, including at least a gauging or measuring head, includes a stationary structure and at least a support structure for the head, coupled to the stationary structure in an adjustable and removable way.

    • For the measuring of thread pitch diameters it has been common practice to use caliper or micrometer attachments in the form of measuring blades or wires rather closely adapted to the specific pitch and flank angle and even type of the thread, resulting in a high number of attachments for general use. The invention is based on the finding that in shaping the protrusions of a set of measuring blades in accordance with the cross-sectional contour of the thread engaging parts of a set of measuring wires, while otherwise adapting the shape of the protrusions with lengths and widths deviating from the circular cross section of the measuring wires, it is possible to provide a set of attachments that will be usable over a much wider range of both thread pitches and flank angles and even for different types of threads. The number of different attachments for general use may thus be drastically reduced, e.g. to only one set for thread pitches of 2-5 mm and two sets for 1-5 mm.

    • The invention provides a device and method for measuring the size and shape of an internal void (B) in a masonry structure (A). The device comprises a rotatable hollow rigid tube (1) which can be inserted through an access hole (C) formed in the masonry structure (A) into the void (B) to be measured. Means are provided for measuring the extent of axial forward movement of the tube (1) through the access hole (C). A probe, which may be a mechanical probe (2) located at or near a leading end of the tube (1) or a laser beam from a laser rangefinder unit (10) located at or near a leading end of the tube (1), is directed laterally of the tube (1) to extend at an angle from the axis of the tube (1 ). Means are provided for detecting when the probe locates a surface of the masonry structure and for measuring the distance between the surface located and the axis of the tube. Thereafter there is a collation of the extent of forward movement of the tube through the access hole, the rotational angle of the tube, the angle between the probe lateral direction and the axis of the tube, and the distance between the axis of the tube and the point of impingement of the probe on the internal surface of the void. From a number of such collations taken at different extents of forward movement of the tube through the access hole and at different rotational angles of the tube, the device includes means for calculating the size and internal shape of the void to be measured.
