Abstract: A device for an arrangement inside a fuel tank, provided with pumps and filters for supplying and filtering fuel that is fed to an internal combustion engine, whereby the fuel is conveyed from the bottom area of the tank through a first filter into a collector chamber and fuel is conveyed from said collector chamber by means of a second pump through a second filter to the internal combustion chamber. Both pumps are arranged in a pump unit. The collector chamber is arranged vertically above the pump unit and the filter with respect to the fitting position of the device and is embodied as an open overflow container, whereby the inventive device can be produced in a rational manner and offers good functionality.

Abstract: A machine for cutting stacked sheets of stock. The machine has a counter for accommodating the stock. The rear of the counter accommodates the stock to be cut and the front of the counter the cut stock. The rear of the counter also accommodates a mechanism for advancing the stack and a baffle for one side of the stack to rest against. A bent is positioned above the counter and accommodates a blade for cutting the stock and a holdfast that can be lowered onto the top of the stack. A control panel and a display panel are positioned on the front side. The machine in accordance with the present invention is characterized by at least one camera (22) at the rear (9) of the counter. The camera monitors the position of the stock in relation to the stack-advancing mechanism (10) or the lateral baffle (12) and displays on the display panel (17) a real-time image (26) of what it can discern.

Abstract: The invention relates to a plate filter element for an air filter comprising a zigzag-shaped, folded strip material made of an activated carbon nonwoven material. The aim of the invention is to improve the dimensional stability of the activated carbon nonwoven material, especially in the area of an end fold. To this end, the invention provides that an end fold of the strip material comprises a sealing which is formed by gluing or fusing an upper side with an underside of the activated carbon nonwoven material.

Abstract: A method of operating a machine for cutting stacks of material in sheets. The machine's basic settings are established in accordance with parametric settings (machine parameters). Specific parameters (program parameters) are permanently assigned to an overall material-cutting program. Individual parameters (routine parameters) are permanently assigned to paper-cutting routines within the overall program. The machine parameters are stored and remain valid until modified or replaced by specifically requested routine parameters. The routine parameters are stored and remain valid until modified. The method allows the operation of the machine to be adapted to the various conditions that occur during the job.

Abstract: A device for connecting two tubular pipe sections. A sealing device is arranged between the pipe sections. At their ends, the pipe sections in each case have a flange-type end piece. The pipe sections are held together by a spring device using a pre-tensioning force, the spring device having a mid-section extending at right angles to the longitudinal axis of the pipe sections. The spring device has a spring element, from whose transverse sides of the mid-section, which extend at right angles to the longitudinal axes of the pipe sections, spring limbs extend. Forming an at least approximate U-shape with the mid-section, the spring limbs extend at least partially over the periphery of the pipe sections, the spring limps each having a centrical cut-out that is adapted to the outside diameter of the pipe sections and in which a pipe section is accommodated in each case in the mounted state of the spring element.

Abstract: A device for connecting two tubular piping parts, in particular piping parts in a motor vehicle exhaust system, has two connector pieces with a sealing device being mounted between the connector pieces. The connector pieces are stressed against each other in axial direction by a spring device. The spring device has a wire spring which surrounds one connector piece at least partially with two spring branches and is supported by this connector piece. The wire spring is stressed against a stop on the other connector with the spring branches or another area of the wire spring.

Abstract: In an arrangement for interconnecting two exhaust pipe sections of a motor vehicle exhaust system with a vibration dampening structure disposed between the two pipe sections, a first one of the pipe sections has a coupling member radially extending therefrom and the second pipe section has a coupling structure connected to the coupling member in a circumferentially elastic fashion so as to permit limited relative rotation between the two pipe sections.

Abstract: In an arrangement for joining tubular duct sections, especially the end sections of pipes of a motor vehicle exhaust system, wherein the end sections are received in one another such that one end section extends around the other in spaced relationship with a seal structure disposed therebetween, the one end section has slots and a spring structure is inserted through the slots into the space between the pipe end sections and has spring legs disposed in the space between the pipe end sections in engagement with the pipe end sections for holding them in firm axial engagement with each other and with the seal structure disposed between the pipe end sections.

The slider is reciprocable by a fluid-operable piston-cylinder unit to an extent which corresponds to the desired adjustment of the screw.

Abstract: The fiber composite for bearing structures for absorption of electromagnetic waves consists in its structure of at least three layers (2, 3, 4, 5, 6, 7, 8, 9) to be different in their electromagnetic material constants, whereby one or more fiber layers (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 23, 24) are used for the layers (2 to 9). The fiber layers demonstrate alternately by layers a high or low electrical conductivity such that the electromagnetic material constants of the layers (2 to 9) composed of the fiber layers (13 to 21 and 23, 24) and binder and the layer thicknesses are matched to one another such that the reflection attenuation is integrally maximized in a given frequency range.

The spectrum of the radiation illuminating the sample can be simultaneously measured with a fourth diode-array spectrometer.

Abstract: The invention concerns a receiver (1) in the probe head of a multiple-coordinate measuring machine in which probe-pin combinations (21) can be replaceably chucked with high precision with respect to their position in space. The receiver contains an isostatic three-point support (14) against which the base (15, 16, 17, 18, 19) of the probe-pin combination is drawn by an electrically operated clamping device. The clamping device is coupled with the control computer of the measuring machine so that a probe change can be effected automatically.In a preferred embodiment, the clamping device consists of a permanent magnet (11) and of an electromagnet (10) by which the field of the permanent magnet (11) can be selectively counteracted or increased to achieve pick-up and release functions. In another embodiment, a motor-driven screw thread performs the pick-up and release functions, and assures that the picked-up probe will unambiguously be drawn into correct isostatic engagement with the three-point support.

Abstract: Two prismatic wedges of a prismatic compensator are rotated in opposite directions by the same angular quantity for adjusting the prismatic effect with the aid of a crossed-over pull wire. The pull wire is changed in direction by means of two rollers. The pull wire encloses the fittings under pulling tension so as to be free of slippage and free of play.

Abstract: Structures subject to a high operational stress, such as weapon launchers, ombustion chambers, artillery barrels and the like, are strengthened dynamically by a counter-pressure generated simultaneously with the load causing the operational stress. The counter-pressure causes a dynamic stress which is effective temporarily to counteract the operational stress. In a weapons launcher, for example, the operational stress occurs in a launching tubular member and the counteracting stress occurs simultaneously in a second tubular member surrounding the first launching tubular member.
