The joint (36) comprises a tubular body (37) having two connecting zones (38, 39) each connected by an end to a tubular element (40) of a fluid transport line, giving continuity to passage of fluid. The tubular body is made of a mixture of an electrically-conductive material such as PVC, with carbon black to give it electrical conductivity. The joint has an internal surface (41) which is destined to come into contact with the transported fluid, and an external surface which is destined to have a grounded galvanic contact. The joint is inserted in the discharge fluid drainage line of a dialyzer filter, in an apparatus for intensive treatment of acute renal insufficiency, for eliminating ECG artefacts due to functioning of peristaltic pumps in the apparatus.

The invention relates to a plate heat exchanger forming between its plates a first flat flow tube in which a first fluid circulates between a first inlet orifice and a first outlet orifice, and a second flat flow tube in which a second fluid circulates between a second inlet orifice and a second outlet orifice. The two flat tubes form parallel arms which extend in a longitudinal direction (L) perpendicular to a transverse air flow traversing the heat exchanger, the first tube being upstream in the air flow and the second tube being downstream.

In an electric steering lock for vehicles, an element for angular locking of a steering shaft is displaced by a driving group between a forward operational position, in which it holds the steering shaft in an angular position, and a retracted resting position in which it allows a free rotation of the steering shaft; the driving group being provided with an electric motor and a mechanical transmission interposed between the motor and the locking element, and with an elastic device cooperating with the electric motor to displace the locking element towards its retracted resting position.

The present invention relates to a packaging machine which has transport means in the form of two transport chains (5, 6) for lateral grasping and transporting of a length of material (7) consisting of packaging material. In particular with longer plants above approximately 10 meters in transport length the stretching property of the transport chains owing to the load has a marked effect on the precision of the transport distance. This results in fluctuations of the transport distance between the two transport chains and therefore distortions of the length of material, which, depending on the type of packaging material, can even lead to tearing of the length of material. In order to minimize these fluctuations, the first transport means (5) has a first engagement element (10) engaging in the first transport means (5) and the second transport means (6) a second engagement element (11) engaging in the second transport means (6), the first engagement element (10) being coupled to the second engagement element (11) in such a way that the two engagement elements are synchronized.

For regulating the lateral buckling of a section of pipe, at least one device permanently applies a force to a point on the section of pipe. The force is preferably applied substantially horizontally and perpendicular to the axis of the pipe. Preferably, two of the devices that apply equal and opposing forces are positioned at a distance from each other along the section of a pipe. Each device comprises a clamp, a cable, a return device and a buoy or a weight.

Power LEDs are implanted in a specially designed printed circuit board (PCB) that is known in the art as a Metal Core Printed Circuit Board (MCPCB). The MCPCB is bended over to so as to have rounded corners having a radius that is not smaller than a determined value depending of the overall thickness of the MCPCB and other factors without any negative effects on the insulating layer and copper traces in the area of bending. In this manner, the surface area of the heat sink used in an LED nail care curing appliance is increased. The MCPCB with installed LEDs with rounded corners thereby follows the natural curvature (based on the shape of a human hand) of the appliance housing, eliminating the need for additional heat sinks or fans to reduce the heat generated by the LEDs.

Means (66) for coupling electrical energy to the interior of the arc tube includes an electrical current-carrying frame member (68) and in-leads (68a) and (68b) sealed into the lamp stem (90) and connected to a base (not shown). A starting source (70) comprises a sealed cavity (72) formed in the press seal (64). A second fill material is contained within the sealed cavity (72). The starting source (70) emits ultraviolet radiation when the lamp (60) is energized, which assists in initiation of the arc discharge within the interior of the arc tube (62). An electrical energy coupler (74) is provided for coupling electrical energy to the sealed cavity (72). The electrical energy coupler (74) comprises an electrically conducting element (76) having a proximal end (78) affixed to the electrical current-carrying frame (68) and a distal end (80) overlying the starting source (70), thus providing a capacitve coupling.

An improved cleaning fluid supply housing assembly for a cascade-type substrate scrubber having a sliding piston configured with a flange with recesses so that the piston is out of contact with the rotating part of the brush core mandrel bearing assembly. Rather, the piston flange outer face only contacts the stationary outer race of the mandrel bearing. The water supply piston is also configured with a full bore to minimize the pressure on the end of the mandrel. A tolerance-controlled leak through the bearing is provided by the configuration of the piston flange to provide a flushing of the area in which wear might be a source of particle generation by a controlled tolerance leak upstream of the brushes. These features substantially eliminate the source of particle generation from contact wear and the contribution of such wear particles into the interface between the brush and the substrate surface being cleaned.

A system and method for transferring a satellite from an initial orbit into a mission orbit. The method includes anchoring to the satellite of an external unit having a tank containing a reserve of propellants. The system includes an autonomous spacecraft having an electric propulsion module and a small internal reserve of propellants, located in a parking orbit close to the initial orbit. The spacecraft with the external unit attached to the satellite is docketed in an initial orbit, to produce a fluidic connection of the propellant tank of the external unit to the propulsion module of the spacecraft. The external unit and satellite is transferred into the mission orbit by the electric propulsion module of the spacecraft supplied with propellants directly from the external unit, thereby releasing the satellite into the mission orbit.

A corrosion-resistant tension member, particularly an inclined cable of a cable stayed bridge, is comprised of a bundle of individual elements, for example, steel wire strands, which in its open area is encapsulated by sheathing, and which within the structure extends inside a guide canal that is formed by a recess pipe. The sheathing—sealing off the front side of the guide canal—is thereby directly or indirectly connected to the structure. Between the sheathing and the entrance point of the tension member into the structure, a connecting pipe is arranged, which on the one hand is detachably connected to the sheathing and on the other hand is connected to the structure by a flange plate.
