A vehicle seat (30) is movable rearwardly with a pivoting action in response to forces applied to the seat in a rear impact. The seat is provided with an energy absorbing unit (1). A clamp (20, 21, 22, 23) is provided which can engage a deformable strip (8) that forms part of the energy absorbing unit (1) when a relatively high impact force is applied, indicative of a rear impact. The clamping action prevents any subsequent rearward movement of the vehicle seat (1).

A method for production of the load-carrying platform of industrial vehicle bodies which are more than 1500 mm wide comprises the operating steps of: forming a first and a second shaped piece (3) of flat material, each piece (3) having a main edge (4) for connection to the other piece (3); welding the main edges (4) together end to end; and bending the pieces (3) of material to produce the load-carrying platform (1). The three steps may be carried out in any order. Moreover, the bending step may also involve the production of a front panel (2) of the body, integral with the platform (1).

A quickly disintegratable compression-molded material characterized by comprising cellulose and erythritol.

In a process to fix a road crash barrier (9) to the road surface, the L-shaped crash barrier base (9, 10) is attached to the road surface (18) by a hexagonal bolt (13) with a threaded shank (14) and washer (12). The bolt has a core diameter DK, a thread diameter DG, and a screw-depth of LE. The screw enters the asphalt to a depth of LB where it is anchored in the hole (7) by a fluid mass (8) to a depth of LF. The installation is described by the relationship: DB DG, DB DK, LB LE and O, 2 LE 0.8 LE. The bolt is anchored in a hardened bonding agent which penetrates into surrounding pores.

A conveying device ( 1 ) which is particular in that the conveying device comprises a plurality of conveying elements ( 2 ), where each conveying element ( 2 ) comprises a chain box element ( 4 ) in which at least one transport roller ( 3 ) is rotatably fixed such that rollers ( 3 ) arranged in adjacent conveying elements ( 2 ) define the conveying device transport plane, and that chain box elements ( 4 ) of adjacent conveying elements are interconnected in such a way that one conveying element may articulate in relation to adjacent conveying elements, and that at least some of the chain box elements in the conveying device comprise drive elements directly engaging and rotating the transport rollers ( 3 ).

A calibrating basket for calibrating the extruded plastic tube has guiding bows(2) carrying guide rolls(4) for the tubular film. The guide rolls are formed by anti friction roller bearings. Each bearing has an inner ring(6) fixed to a guide bow(2) and a rotatable outer ring(7) supported via rollers(8) on the inner ring. An anti-adhesion coating covers the surface(11) of the outer ring. A gap exists between rollers on the guide bow.

The device (1) comprises a base (2), carrying a servo motor (3) and attached to the frame of a machine center. A carriage (6) with a vertical shaft (8) on top can be moved on two telescopically arranged rails (4,5) joined horizontally to the base (2). The tool holding elements (16,17) are positioned at the upper end of the shaft (8) and can be fixed with a locking unit (18). A control plate (12) is located at the second rail (5) acting in combination with a guiding roll (10) in order to facilitate a swivel motion of the tool carrier (15).

A frame structure consisting of two compound units provided with mutually facing grooves undercut on either side, in which the first compound unit can be attached in a desired position to the second compound unit via a detachable coupling which comprises a turning part which can be turned from the outside manually via a handle about its longitudinal axis by about 90 DEG into its coupling or decoupling position, and which in its coupling position positively engages by means of a T-head at its one end in one of the two grooves and by means of anchoring means at its other end in the other of the two grooves and can be locked in this coupling position by means of an anti-rotation device. To connect the two compound units to each other without special tools, but above all to be able also to detach them from each other again, it is proposed according to the invention that the anchoring means comprise a punched part which is arranged longitudinally displaceably in the one groove and bears the turning part which is freely rotatable relative to it and that the handle comprise a resilient element connected securely against rotation to the turning part, which element in decoupling position extends in relieved state or under only slight stress between the two compound units and in coupling position engages under bending stress behind a holder.

A device for preparing and ejecting polymeric cement made from at least two pre-packaged components comprises a tubular vessel including a first axial end wall having a closed outlet, and a second axial end wall having an aperture. A first starting component of the polymeric cement is present inside said tubular vessel near the first axial end wall. A hollow shaft extends through said aperture of the second axial end wall. A piston element comprises a closed container filled with a second starting component of the polymeric cement. The piston element is selectively lockable to the shaft. The container has a bore and is slidingly engaged upon said shaft. An agitator element is secured to one end of the shaft. Furthermore opening means for providing an opening in the closed container are provided. The hollow shaft is provided with a gas permeable filter means.

A method for making a plate-like fiber-reinforced product to be used as building or packing material, the method comprising: placing fibers on a lower laminate; applying a binding agent on the fibers so that the fibers are surrounded by the binding agent; transferring the fibers with binding agent between the lower laminate and an upper laminate between lower and upper rotating pressing plates; allowing the binding agent to foam up, expand and harden between the upper and lower pressing plates. A manufacturing apparatus and a plate-like product are also indicated.
