A belt for a material web producing machine and a process of producing the belt. The belt includes a plurality of long-chain strength supports arranged to form interstices and a filler at least partially filling the interstices. The process includes forming a sheet from a plurality of long-chain strength supports with the sheet including a plurality of interstices disposed between the long-chain strength supports, and filling at least a portion of the interstices with a filler.

A flat reflector lamp for fluorescent bulbs is described. The lamp has a self-supporting reflector with an enclosed hollow portion for mounting an electronic ballast. Electrical sockets on a pair of lamp end plates function as mounts for fluorescent lamps. A circuit board mounted on guide strips within the enclosed hollow portion of the lamp has spring contacts in electrical contact with at least one of the electrical sockets.

A DC/AC converter is provided for contactless, inductive transfer of energy, which transfers arbitrary voltages to a removable user with the aid of a high-frequency pulse generator. The pulse generator produces asymmetric pulses, which provides two different voltages to the user, depending on a to coupling orientation. Further, the pulse generator is built in such a way that, if a user is absent, it is not excited to oscillation and, as a result, uses substantially no energy at all in a stand-by operation.

A fluorescent lamp having electrical conduits on the outer surface of the gas discharge vessel. Electrical power is supplied to one end of the fluorescent tube, via a ballast assembly which is connected to a first electrode in the tube. The electrical conduits on the outer surface of the tube carry power to the electrode at the other end of the tube, thus eliminating the need for wiring within the tube mounting assembly.

Stock inlet of a paper machine that includes at least one stock suspension supply, a diffusor block having a plurality of tubular elements, dividing elements which extend across a width of the machine, and a stock inlet aperture having a top wall and a bottom wall. The dividing elements are located between the top wall and the bottom wall, so that a plurality of suspension conduits are formed, which extend across the width of the machine. Further, the stock inlet aperture is positioned one of adjacent one wire and between two wires. The suspension conduits include a first region and a second region disposed downstream of the first region, with respect to a stock flow direction. The first region is formed by flat boundary surfaces which extend across the width of the machine and converge in the stock flow direction, and each of the dividing elements has a sharper convergence of surfaces in the second region than in the first region. The plurality of tubular elements are associated with a turbulence generating element to produce secondary turbulence currents in partial suspension flows conveyed through the plurality of tubular elements. In this way, the secondary turbulence currents overlap a primary current of each partial suspension flow, and all of the dividing elements have a contour and an arrangement so that the second region for each suspension conduit is of equal length and has an identical cross sectional course.

Dryer section of a machine for at least one of producing and processing a web of material. The dryer section includes at least one heatable drying cylinder having a circumference, at least a part the circumference adapted to be surrounded by the material web, at least one support band arranged to surround the at least a part of the circumference, and a sealing band arranged to surround the at least a part of the circumference. An overpressure cap is arranged to receive one of a liquid and gaseous medium and is adapted to apply a pressurized one of the liquid and gaseous medium on the at least one drying cylinder. A temperature of the medium is lower than a temperature on an outside of the part of the circumference. At least one second support band is arranged around the at least one drying cylinder and is positioned between the at least one support band and the sealing band, wherein the at least one second support band has a coarser structure than the at least one support band.

The invention concerns a new improved alternative to the previous Edison sockets and the so-called bayonet sockets which are used to mount electric lights. A lamp base and socket are provided which have cooperating profiled surfaces which serve to guide the lamp base into its proper position in the socket and to lock the base into position. Supporting surfaces are provided on the lamp base and lamp socket which form a pivot for releasing the lamp from the socket.Despite high locking forces, a tilting movement of the lamp and the lever translation produced by moving these surfaces permits easy release of the lamp from the socket.

The invention concerns a gas discharge lamp or vessel wherein at least part of the lamp is in the form of a spiral. The windings of the coils forming the spiral are tightly-spaced (less than 1 mm apart). In addition to providing high amounts of light, the compact packaging resulting from the design offers safety advantages in that the electrical contacts are located deep within the vessel interior. Thus, the opportunity of contacting live electrical contacts in the event of glass breakage is lessened.

A shockproof (touch-safe) lamp holder and adapter system which replaces conventional screw-type holders and bayonet holders is disclosed. The lamp holder complies with the list of requirements demanded by testing authorities for many years.The new lamp sockets can be used with an adapter in conventional lamp holders, and the requirement that the adapter cannot be removed again after insertion without any tools is fulfilled by a reversing lock.
