Abstract: In order to connect a connection piece (10), which is, for example, a pipe coupling or a mounting or a fitting, to a thermally insulated conduit pipe (1), a clamping sleeve (9) with an internal thread (8) is screwed in between the internal pipe (2) of the conduit pipe and the insulation layer (3) of the conduit pipe. A connection body (11) with a plug sleeve (13) is arranged in the internal pipe beforehand. The clamping sleeve (9) acts indirectly on the connection piece (10) by way of a retaining ring (14) in order to press the connection piece against the end face (5) of the internal pipe (2). In this way, the distance between the insulation layer (3) and the casing (4) of the conduit pipe is dispensed with and inaccuracies when cutting the conduit pipe to length can be compensated.

Abstract: The invention relates to a pneumatic actuator composed of cuts of a gas-tight film which are interconnected so as to form hollow film elements that are gas-tight towards the outside. The hollow film elements are interconnected by means of air ducts while forming a fan-shaped structure from a cross-sectional perspective. The actuator, which is fastened to a component, is swiveled about a common edge of the hollow film elements when compressed gas is delivered via a connection. The swiveling movement of the actuator can be used for gripping and holding objects or transmitting optical signals.

Abstract: An electrical circuit module in which structural elements of the circuit module are foamed or cast over with synthetic resin. At least one component is located in the interior of the resin and has an actuating shaft allowing adjustment of the component. An extension shaft that is rotationally symmetrical and has a driver is coupled to the actuating shaft. The extension shaft has a rotation-symmetrical bead and is embedded in the synthetic resin in a positive-fitting manner. The extension shaft also has an adjustment and protruding to the outside of the resin, and a surface which forms a separation layer toward the resin.

Abstract: A flat conductor foil is used on which the circuit is etched upon. After equipping this conductor foil with electronic structural elements the conductor foil is folded at predetermined folding edges for adaptation to the device shape. For forming the housing element this circuit unit is sheathed with a plastically mountable hardening synthetic material. The housing element is thereby separated into housing partial parts in such a manner that the housing partial parts may be joined together into a closed housing element when folding the conductor foil. Thereby, the housing partial parts are mounted onto the folding segments of the plane, still unfolded, but equipped conductor foil, whereby (before the folding) folding pieces are obtained for the individual folding pieces which protect the structural elements and the soldering and stabilize the foil for the joining.

Abstract: A lubrication monitoring device for heavy duty diesel engines includes a plurality of measuring receivers connected at one level to driving spaces of the engine. Each receiver is assembled of a socket part secured to the wall of the engine and enclosing a lower and upper padding of resilient material pressed together by a pressure plate fastened to the top of the socket. Opposite lateral walls of the socket are formed with cutouts for receiving a ribbon cable which is integral with lateral elongated channels connected respectively to an underpressure and overpressure pump. The upper padding is provided with a connector block carrying a plurality of fork shaped contacts and with two hollow connection pieces which upon compression of the upper padding penetrate the elastic material around the elongated channels while the fork shaped contacts penetrate the insulation of the cable wires.

Abstract: A direction-sensitive sensor of the type which is particularly useful as a proximity sensor, is provided with a sensor part which is rotatively connected to a further sensor part via a rotary joint consisting of a bracket connection. The sensor parts are rotatably mounted about an axis which is perpendicular to the joint axis in the desired rotation angle position in a holder. Electrical connecting elements are designed as circular rings or segments of circular rings which are arranged concentric about the joint axis and are firmly connected to the connecting brackets. At least one of the brackets is provided with a sealing element which seals out the environment. In this manner, a moisture-proof and electrically highly conductive connection is achieved between the sensor portions. Moreover, the sensor portions can be arranged in any desired angular position while maintaining a good seal which prevents the environment from affecting the connection.

Abstract: In a method and a device for controlling a lubrication film between a bearing surface and a shaft surface of the bearing assembly an electric circuit is provided, interconnected between the shaft and the housing of the bearing, in which a thermoelectric voltage is produced by friction heat which is generated at a contact between the shaft and the bearing when a break in the lubrication film occurs, and which termoelectric voltage is used as a voltage source of the electric circuit.

Abstract: A treatment method for the sulfur- and particle-containing hot waste gas of an incineration process where refuse is burned in the presence of air comprises the steps of preheating air with the hot waste gas, passing the hot waste gas through one side of a heat exchanger, passing air through the other side of the heat exchanger and thereby heating the air and cooling the waste gas, and desulfurizing the cooled waste gas. At most a portion of the heated air is fed directly to the incinerator and there used to combust the refuse. Another portion of the heated air is mixed with the cool desulfurized gas. The mixture of cool desulfurized gas and the other portion of the heated air is then released to the atmosphere. The preheating of the air is done in a second heat exchanger separate from the first-mentioned heat exchanger and traversed by the waste gas and air. In addition particles are filtered from the waste gas between the heat exchangers.

Abstract: An optical sensor is disclosed comprising a transmitter which transmits a light beam, a receiver 2 for receiving reflected light and a reflector for directing light from the transmitter to the receiver. The reflector converts the wavelength of the light transmitted by the transmitter and the receiver is tuned to detect light of the converted wavelength. Objects located in the area between the reflector and the combination transmitter/receiver are detected as they do not convert the wavelength of the light from the transmitter even if they reflect light to the receiver.

Abstract: A cable lead-in arrangement for encapsulated electrical equipment having a compressible sealing member adapted to enter an opening in the housing. The compressible sealing member is provided with window-like openings through which protrude conductor elements of the cable for engaging ring-shaped contact elements arranged in the inner surface of the opening in the housing. The arrangement is further provided with a compression element which is adapted to apply an axially compressive force to the sealing member so as to apply an advantageously high contact pressure between the contact elements of the opening in the housing and the conductor elements of the cable. Such contact pressure also ensures against the introduction of environmental influences into the equipment. An embodiment is presented for holding the cable at an angle with respect to an axis of the sealing member.

Abstract: A circuit board having a window for receiving an electronic device substantially in the form of a plate is provided with elastic holding tabs of at least two different lengths which project into the window, the tabs forming the ends of conductor runs on the circuit board. Upon a pushing of the plate through the window, the short holding tabs snap back and the plate becomes clamped to the circuit board by the holding tabs, these tabs also serving to complete the electrical coupling between the conductor runs of the circuit board and contacts on the plate.
