Abstract: A floor construction covered with ceramic tiles, in which a film-like plastic mat having support elements disposed in a uniform area distribution, hollow towards the underside, capable of support, projecting out beyond the top of the mat, is applied on the sub-floor. Channels carrying open water are formed between the support elements, and a water-permeable or vapor-permeable covering in the manner of a non-woven fabric or woven fabric is disposed on the support elements. The plastic mat is embedded and attached, supported in a still soft, hardening thin-bed mortar layer on the sub-floor, over its full area, in the region of its lower contact surfaces. The ceramic tiles are laid and attached on the covering in the manner of a non-woven fabric, directly, with a thin-bed mortar layer.

A second frame is coupled to the first frame and guides the first frame in a specific direction perpendicular to the connecting direction. Each of the contacts includes an insulating elastic member and a conductor combined with the elastic member. The conductor includes portions protruding from the principal surfaces, respectively.

Abstract: The invention relates to a device for protecting an electrode during the resistance welding of workpieces, in particular sheet metal. Said device comprises a strip that is placed over the electrode and can be displaced in relation to the latter, a backing material of said strip having an electrically conductive coating. To improve the welding quality, the coating is applied to the opposite side of the strip from the electrode and consists of a material, whose hardness is less than that of the backing material of the strip. The soft, electrically conductive coating improves the transfer of current from the electrode to the workpiece, thus preventing weld spatter and improving the welding quality.

Abstract: The present invention relates to a camshaft (1) having an inner shaft (3) arranged coaxially in an outer shaft (2) and mounted to rotate with respect to the outer shaft (2). The camshaft (1) has a first phase adjuster (7) and a second phase adjuster (8), the first phase adjuster (7) adjusting a phase relation of the inner shaft (3) and thus of the first cams in relation to a drive, in particular a crankshaft, while the second phase adjuster (8) adjusts a phase relation of the outer shaft (2) in relation to the drive. Thus the first and second phase adjusters (7, 8) each have a switchable hydraulic valve (9, 10), both being arranged inside the inner shaft (3).

Abstract: An electrical device is disclosed for use in a wall box having a series of buttons that can either be rocker buttons or push buttons. These buttons can be supported by springboards formed integral with a support board. The springboards are for biasing the series of buttons. Much of the device is housed within a housing formed at a first end by a body and a second end by a strap coupled to the housing. The strap extends beyond the body, wherein this strap can be used to dissipate heat from the device. Inside of the housing can be at least one circuit board which has switches, which can be used to receive instructions from a plurality of buttons. In one embodiment, a plurality of light pipes are adapted so that they are housed at least partially inside of these buttons. At least one portion of the light pipe can be formed as a shaft and adapted to extend out from this housing and down to a light emitter disposed on the circuit board.

Abstract: An implant for intersomatic fusion of two adjacent vertebrae, particularly by an operation that was performed in posterior manner. The implant has a first implant part and a second implant part that is adjustable relative to the former, for the purpose of distraction. The first implant part and the second implant part are structured so that they supplement one another, in a complementary manner, in the non-distracted state, to form a pipe that is divided in the longitudinal direction. Guide surfaces that extend radially in the distraction direction, and rest against one another are formed on the first implant part and the second implant part. The relative position of the guide surfaces is fixed in place. An instrument for the placement and distraction of the implant is also provided.

Abstract: The invention relates to saturating various fluid media with oxygen, for example for aeration and can be used for the food industry, pharmaceutics, perfumery and cosmetics, physio- and aromotherapy, water supply systems, fishing and agriculture, including producing beverages, good additives, drugs, novel perfume and cosmetic products, inhalation and bathing, for improving the habitat and increasing a productivity of fish and other useful animals and microorganisms in aquariums, ponds, pools and for producing means for processing plants and animals. The inventive method for processing a fluid medium consists in passing an oxygen-containing gas flow which is pre-saturated by phyto-excretes of vegetating or cut plants through said medium.

Abstract: An arc fault detector, as a stand alone device or in combination with a circuit interrupting device such as a ground fault interrupter (GFCI), protects from potentially dangerous arc fault conditions. The device utilizes a line side or load side series connected inductance having an air or magnetic core to generate the derivative di/dt signal of the arc current in the conductor. The derivative signal is fed to an arc fault detector where it is analyzed for the presence of arcing. The device can have two series connected inductors inductively coupled to each other such that the signal from one inductor is inductively coupled into the other inductor for coupling to the arc fault detector.

The attachment head is held in the attachment element by a press fit.

Abstract: The invention relates to the establishing of a connection between steam generator heating surfaces made of austenitic materials and a collector and/or distributor made of martensitic or ferritic materials or of a nickel-base alloy. In order to extend the expectation of serviceable life of the connection, the pipe nipple of the reservoir used as a collector or distributor is made of a nickel-base alloy and directly welded to the collector wall in such a manner that an axial gap remains between the connecting branch and the collector wall. In a connection of the aforementioned type between steam generator heating surfaces made of austenitic materials and the pipe nipple or the pipe nipple and the collector made of martensitic materials, the coefficient of expansion of the material of the pipe nipple has a particularly good effect upon the serviceable life of the entire connection.
