Abstract: The device embodying the invention applies to a variable-moment vibrator comprising at least two trains of eccentrics driven in rotation by a variable-speed motorization, the variation of the vibratory moment being obtained by a phase shifter which generates a phase shift between the rotary motion of the two trains of eccentrics. It comprises at least one accelerometric detector subjected to the vibrations generated by the vibrator, a means for deducing, from the accelerometric data detected, a value representative of the harmfulness of the vibrations, a means for entering a set value and a processor which acts on the phase-shift control of the phase shifter and/or on the component controlling the motorization speed variation in order to maintain the value representing the harmfulness of the vibrations at a level equal to or lower than the set value.

Abstract: Method and apparatus are provided for visibly outlining the energy zone to be measured by a radiometer. The method comprises the steps of providing a laser sighting device on the radiometer adapted to emit at least one laser beam against a surface whose temperature is to be measured and positioning said laser beam about the energy zone to visibly outline said energy zone. The apparatus comprises a laser sighting device adapted to emit at least one laser beam against the surface and means to position said laser beam about the energy zone to visibly outline said energy zone. The laser beam may be rotated about the periphery of the energy zone. In another embodiment, a pair of laser beams are projected on opposite sides of the energy zone. The laser beam may be further pulsed on and off in a synchronized manner so as to cause a series of intermittent lines to outline the energy zone. Such an embodiment improves the efficiency of the laser and results in a brighter laser beam being projected.

Abstract: The invention provides visual displays, and methods of operating such visual displays, in which use is made of a plurality of light emitting diode elements which are arranged to emit a respective colour when suitably energised. Diode elements having different colours are juxtaposed so that when one or some of the juxtaposed elements are energised they show a first colour, and when others of the juxtaposed elements are simultaneously energised, the elements collectively generate a further colour or colours which is or are a derivative of their respective colours. Examples are described of use of the visual displays for such purposes as the provision of advertising materials, decorative materials, and variable background shapes, colours and textures, such as for display and furnishings.

Abstract: A lattice girder generally including a top rail, a bottom rail, vertical end posts and slanted crossbeams, wherein all of the members consist of uniform hollow sections that may be fitted into one another and thereby rigidly interconnected. The girder rail consists of two half-sections (18,19) internally provided with longitudinal flanges (20, 21) having transverse serrations so that the two half-sections may be permanently secured to one another by pressing them together with the serrations in mutual engagement. The end of a slanted crossbeam (24) having notches (at 25 and 26) is inserted into openings (22,23) in the half-sections to lock and engage the rail. Weldless lattice girders may thus be produced, in particular for forming a walkway guardrail.
