In the present stepping mechanism two stepping motors are driven in synchronism with each other by drive pulses, the supply of which is controlled by an output pulse from an electromechanical comparing device which is stepped by one of the two motors whereas the other motor steps a movable member, for example, a tool support from one point to another.

The invention relates to an outer building wall heating device with a heat exchanger comprising a mainly reversed U-shaped outer wall part, closed at the bottom end, an inner wall part lying inside the outer wall part and having a mainly triangular shape with downwardly directed top lying at some distance above the bottom of the outer wall and an air inlet stud formed in the rear wall of the outer wall and an air outlet stud formed in an inclined partition having its under edge connected to the ...

A transportation vehicle includes a fluid tempering arrangement to supply a gaseous and/or liquid, heated and/or cooled, fluid such as water. 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 ...

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 pr...

An information and notification system onboard an aircraft includes a databus that receives information transmitted from outside the aircraft via an interface and a director or control unit, as well as information from onboard data storage units via a flight attendant panel, whereby the information content can be selected, changed, and controlled. The databus may be a hard-wired or wireless databus, by which the information is provided to variable universal notification displays incorporated in ...

A crotch belt (20) which is one component of a body restraint belt includes an elastic plate (21) having bending elasticity, and a buckle (22) mounted on an end of the elastic plate (21). 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).

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.

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 deflect...

In an apparatus for determining loads on fiber composite components (1), especially of vehicle and aircraft parts, strain gages (3) are integrated in the components (1) for determining strains. The strain gages (3) are connected with an evaluating apparatus (4), for monitoring and determining loads that tend to cause damage. The strain gages (3) are preferably integrated into the fiber composite component (1) such that the measuring grids (5) thereof are laid between individual fiber layers (2) ...

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.
