Abstract: An electrical supply device with a conduit and movable electrical connector, includes conduit sections (1) in an insulating material, in which are disposed electrical conductors (2) interconnected at the level of the junctions of the conduit sections (1); joint covers (3) for connection of the conduit sections (1) insulating the electrical connections of the electrical conductors (2); at least one supply box (4) in line or at one end, by closure caps (5) for the ends of the electrical supply line formed by the conduit sections (1); suspensions (6) for the conduit sections (1); and at least one collector carriage (7) permitting directing the electrical current toward any fixed or movable receiver.

Abstract: A connection device that is modular and has large clearance and that is constituted by two insulating casings (1 and 2) installed through a partition, a first casing (1) being mounted on a movable partition (3) and the other casing (2) being mounted on a fixed partition (4). The first casing (1) has at least one conductive pin (5) and the second casing (2) has at least one contact receptacle (6) of a shape corresponding to that of the conductive pin (5). The conductive pin (5) and the contact receptacle (6) are mounted on the partitions (3 and 4) only for limited elastically opposed pivotal movement relative to the partitions (3 and 4).

Abstract: Fountain permitting the release of active agents into water originating from a well, comprising a passage for circulating the water drawn from the well around a cartridge containing the active agent to be diffused and for keeping this cartridge immersed in water when water is not being drawn from the well.

Abstract: A method and apparatus for checking the width and parallelism of margins following the centering of a print with respect to a support. The support is moved in front of two opto-electronic reading devices with the margins to be checked arranged transversely with respect to the direction of movement of the support. The reading devices are used to produce two counting periods for each margin, the widths of the periods corresponding to the widths of the margin at two points thereof. Clock pulses are produced depending on the movement of the support by means of an opto-electronic detector. Clock pulses appearing in the counting periods are counted and the resultant count compared with maximum and minimum reference values to check the width of the margins. Clock pulses appearing in one of the counting periods are counted only when the counting periods do not coincide with regard to time and the number of pulses counted is compared with a reference value representing the tolerance limit of non-parallelism.

Abstract: A method and apparatus for checking the width and parallelism of margins following the centering of a print with respect to a support, wherein the support is moved in front of opto-electronic reading devices such that the margins extend parallel to the direction of movement. A number n of photosensitive member are distributed in a linear manner transversely with respect to the direction of movement of the support, the number of sensitized photosensitive members of the reading devices producing a signal greater than a threshold level is counted for each margin, the number of members counted is compared with a reference value, and the difference between the numbers of members counted at two different points of each margin is compared with a reference value. The first comparison provides a measure of the width of the margin, and the second comparison provides a measure of the parallelism of the margins.
