Abstract: A fixture includes a hollow body adapted to be secured in an opening of a tub by a ring nut which is screwed to the body in such a manner that the wall of the tub is clamped between the hollow body and the ring nut. A ring is mounted on the body so as to cover an outer edge of the body defining the periphery of the end surface. The ring has a front wall that covers the end surface of the body and is to be situated between the end surface and the wall of the tub. The hollow body is also provided with a vent through-hole and a second through-hole extending from a recess in the end surface of the body. Sealant can be injected through the second through-hole into the spaces delimited by the boy, the ring and the wall of the tub.

Abstract: A bathtub, in particular a whirlpool bath, includes a pair of handles for aiding one into and out of the tub body, and control and actuation elements, as well as water delivery elements mounted to the handles. These elements include an actuator for actuating the plug provided to stop up the drain, an actuator in the form of a control valve for mixing hot water with cold water so as to achieve a single flow of water at a desired temperature, a hand-shower, an actuator to divert water to an extractable nozzle of the hand-shower, a control element for starting and stopping the operation of a water circulating pump and an air blowing pump of the whirlpool bath, a plug of a reservoir for liquid disinfectant, and a switch to actuate a valve which admits the liquid disinfectant into a water circulation circuit of the tub. One of the handles which accommodates the extractable hand-shower also includes another water delivery element in the form of a water outlet through which water cascades into the tub body.

Abstract: Apparatus with an element for detecting and focusing the electromagnetic radiation emitted by the flame of a burner, and with an element formed by a light-conductive bundle of fiber optics for transmitting and separating the radiation of different wavelengths, which are received and analyzed by separate sensors.

Abstract: A method and a device for monitoring the drive motors for each pair of coaxial wheels of a railway traction system, including cyclically measuring representative quantities of the mechanical torque temporarily developed by the motors, comparing such quantities, and disconnecting both motors from the electric power supply whenever the result of the comparison shows a difference greater than a previously established value. Disclosed also is a method of cyclically memorizing the temporary value of a parameter of each motor, commanding a variation of such parameter by a small pre-established quantity, calculating the value that such controlled parameter should reach as a result of such variation, comparing the result of the calculation with the effective value reached, and disconnecting the power supply to the motor whenever the result of such comparison is not equal to or less than a pre-established quantity.

Abstract: A bogie for railway platform vehicles has mounted on its frame a swinging transom having a central portion thereof connected to the body of a platform vehicle. The transom has opposite sides thereof shaped in the form of inverted, generally L-shaped supports to the upper ends of which are connected by a suspension to the upper surfaces of two box-shaped elements which are secured to opposite sides, respectively, of the bogie frame. The frame is supported for movement on a plurality of wheels, each of which is supported for rotation in one end of a U-shaped arm, the opposite end of which is connected by a coupling and a primary suspension to the upper surface of one of the box-shaped elements.

Abstract: A hydromassage carpet is formed by an envelope of two sheets of suitable soft and flexible material, which are joined together with a peripheral weld and further welds effected on the inner part thereof defining two distinct ducts. These ducts include a first sealed duct to be filled with a suitable fluid so as to form a practical mattress, and a second duct connected through a feeding pipe to a compressed air generator and provided at its upper part with holes. The compressed air generates in the bath the desired hydromassage effect by passing through the holes. Inwardly of the peripheral weld are provided several circumferential toes at whose centers relevant central welds extend over an amount sufficient to form a plurality of toroidal elements. The lower parts of these elements, when resting on the bottom of the tub, define cavities similar to those of suction cups and therefore, carry out the same function thereof.

Abstract: A water massage mat is disclosed which comprises a substantially rectangular cover formed of two leaves of suitable flexible material welded together along weld lines so as to form a structure similar to a small air mattress. The weld lines include a perimetrical weld line extending along the perimeter of the cover and a second internal weld line configured so as to define a first hermetically sealed channel and a second channel closed at one of its ends and connected at its other end to a feeder pipe which is adapted to be connected to a source of compressed air. These internal weld lines, as viewed from above are serpentine shaped. Small holes are formed in the upper surface of the second channel and are capable of allowing the compressed air from the feeder pipe to flow out of the second channel so as to generate a water massage effect. A plurality of suction cups fasten the cover to the bottom of a tub or basin.

Abstract: The invention relates to an apparatus for the entrenching of pipes in underwater beds, of the type in which a framework, provided with excavating means, is positioned across the pipe to be entrenched and dragged along the pipe so as to excavate two parallel trenches adjacent to both sides of the pipe, the pipe being entrenched due to the collapsing (either spontaneous or caused by disgregating means) of the bed zone thus remaining under the pipe already laid onto the bed. The excavated material is removed by means of a pump and discharged again, at a predetermined distance from and rearwardly of the framework, on the entrenched pipe. The framework is provided with side supporting skid members, by which furthermore the entrenching height is adjustable.

Abstract: Apparatus is provided for loading poultry from a rearing house into a series of hen-coops arranged in vertical rows on a transport vehicle. The apparatus includes an elevator conveyor which takes the animals from an assembly enclosure to a vehicle movable transversely of the elevator conveyor. This vehicle comprises a first horizontal conveyor extending parallel to the longitudinal axis of the vehicle and arranged to receive animals from the elevator conveyor, an adjustable-inclination conveyor disposed alongside the first horizontal conveyor, a second horizontal conveyor disposed transversely to the first horizontal conveyor and arranged to transfer animals from that conveyor onto the adjustable-inclination conveyor, and a pneumatic forced-delivery unit located transversely at the output end of the adjustable inclination conveyor.
