Abstract: A composite sandwich structure is produced by providing a core structure, applying cover layers on opposite sides of the core structure, and forming an edge seal. The core structure has a folded cell structure with fold valleys forming continuous open channels with open ends and/or open channel sides at edges of the core structure. The channels extend along and are bounded between the fold valleys and the cover layers. The edge seal is formed to have a limited spatial volume in an edge region at an edge of the core structure, to close and seal open ends and/or open channel sides of the channels of the core, without an uncontrolled penetration of the seal material from the edge region to a greater depth into the open channels.

Abstract: Dynamically measuring the unbalance of a rotor arranged in a device housing (1) and rotating at high angular velocity, wherein the rotor is supported in a separate bearing housing (14), involves the following steps: fastening the bearing housing (14) on the device housing (1) with interposition of resiliently yielding elements (6) so that the bearing housing (14) can be moved relative to the device housing (1) in at least two spatial dimensions and the rotor is arranged in a working position in the device housing (1) suitable for driving, accelerating the rotor, measuring the vibrations induced by unbalance while the rotor rotates at a substantially normal working speed, determining the phase position of the induced vibrations to the relative position of the rotor at the measuring speeds, and using the measured vibrations and the phase position to determine the unbalance of the rotor to be compensated.

Abstract: A weaving machine starts-up in slow speed operation during a first weaving cycle following the machine start. To help avoid weft breaks, a method is provided to hold a weft thread inserted into the loom shed during the first weaving cycle. A sensor monitors the weft insertion. The inserted weft thread is held by binding threads at a location downstream from an inlet side of the loom shed, before the weft thread is bound by the warp threads. The binding of the weft thread by the binding threads is carried out dependent on a signal of the sensor.

Abstract: In a method for surface blasting hollow spaces or cavities, especially cavities of gas turbines, shot balls are accelerated with the aid of at least one vibrator, whereby the ultrasonically accelerated shot balls are directed onto surfaces of a cavity that is to be blasted. The vibrator is preferably positioned with a small spacing distance, preferably on the order of magnitude of the diameter of the shot balls utilized for the blasting, from the cavity to be blasted.

Abstract: A fuel tank of a spacecraft stores a liquid fuel and a pressurized propellant gas that drives the fuel out of the tank though a fuel extraction arrangement including a reservoir or fuel collection container and a tank outlet. A spiraling or J-shaped or hook-shaped fuel collection channel and plural obliquely sloping fuel flow channels connect the fuel collection container to an outlet pipe of the tank outlet. The channels are configured, dimensioned, oriented and arranged to ensure that fuel will be retained in the outlet pipe without leaking back into the fuel tank, even when the tank is oriented horizontally and has a low tank filling level. These structures produce a capillary pumping effect and use the surface tension to separate the fuel from the propellant gas, and allow the inner space of the collection container to be completely filled with liquid fuel.

Abstract: A tire mounting apparatus includes a mounting head that is rotated by a drive shaft and slidably carries two adjusting plates. A push rod extends coaxially through the drive shaft, and a deflecting rod slopes laterally from the push rod through openings in the plates. The deflecting rod has two sloping actuating surfaces with different slope angles that engage in the openings of the plates to cause different sliding displacement of each plate by an axial actuation of the push rod. A bead deflector and a pressing roller are respectively mounted on the plates so they can be adjusted to different wheel rim diameters. A toggle lever and/or a pivot joint adjust a pivot angle of at least one of the tire mounting tools to remain tangential to the wheel rim circumference while it is slidingly adjusted to a different wheel diameter.

Abstract: Insulated electrical conductors for installation in a vehicle, such as an aircraft, are further protected by a guard hose or tubular conduit member. Two or more such guard hoses or tubular conduit members are interconnected with each other by at least one spacer preferably, but not necessarily, integrally formed with the guard hoses or tubular member, whereby the separation of different types of electrical conductors and their installation in an aircraft are facilitated.

Abstract: A fluid dynamically effective surface of a device moving in a fluid, especially a lifting surface of a flying machine, has an elastic axis extending in the span direction of the surface, and an adjustable control surface. The lifting surface is elastically deformable in a bending direction and/or in a torsion direction about the elastic axis, due to and dependent on the adjustment of the control surface, while changing the induced fluid dynamic drag. A control and/or regulating arrangement is provided for adjusting the control surface in the sense of minimizing the induced fluid dynamic drag of the lifting surface.

One end of the elastic plate (21) is fixed to a fixing point (23) under a seating surface (4). While the crotch belt (20) is not connected to a waist belt, the crotch belt (20) is positioned along a front part of the seating surface (4) so as to be close to it by elastic force of the elastic plate (21).

Abstract: An electronic device (1) has a base plate (2) and an electronics housing (3) connected thereto, with a bonding contact terminal (5). The latter is supported relative to the base plate (2) via a supporting body (6) in such a manner that the supporting body (6) exerts a pre-stressing force onto the bonding contact terminal (5). Due to this support of the bonding contact terminal (5), its position is well defined during the bonding procedure. A secure bond is the result.

At least one thermochemical reservoir is in heat exchange relation with a conduit system, having at least one valve and a controller that controls the transfer of heat between the fluid and the thermochemical reservoir to adjust the temperature of the fluid provided to an outlet. Preferably two interconnected thermochemical reservoirs respectively contain hydride-forming metals having different hydrogen sorption-desorption temperatures. By sorption and desorption of hydrogen in the two reservoirs, heat energy produced electrically during low electrical demand can be chemically stored and later released for heating the fluid during high electrical demand.

Abstract: A receiver is synchronized with a first clock frequency or signal of a transmitter for the proper reception of transmitted and received signals, such as data carrying signals (DS). The first clock frequency is for example a carrier frequency. A local oscillator generates a second clock frequency or signal in the receiver. Cycles or impulses of the second clock signal are counted between predetermined flanks of the received signal (DS) to provide a count (N). Based on the second clock signal and the count (N) a first ratio (TV) is provided that represents a first ratio between the first clock frequency or signal and the second clock frequency or signal. The first ratio is compared with a predetermined or given second ratio (TV) to provide a comparing result. The predetermined second ratio is then updated in response to the comparing result to provide an updated ratio (TV?). The present circuit is constructed to perform these steps.
