Abstract: A container of hardened, fiber-reinforced synthetic resin and high stability is manufactured by forming a wound-up structure on a shaping core born on the shaft of a winding machine together with fittings for the two open container ends, of different size, and being clamped against the two core ends by means of fixing members held in position on the winding shaft during winding. One of the fittings is provided with an annular groove for anchoring the wound-up structure therein. The fixing members and fittings are of such shape that the winding affords a wound-up structure having end openings of equal size so that a geodetic depositing of the wrapped layers is possible. After the structure is hardened, the portion thereof extending beyond the fitting having an opening of larger diameter than that closed by the other fitting is cut off, so that a container closed by the first fitting and open through the second fitting is obtained.

Abstract: A conveying apparatus for panels is equipped with two revolving endless conveyor belt members such as chains etc. The chains are connected with each other with successively arranged transverse organs such as cross bars. On each cross bar there are mounted displaceably with braking two panel-engaging devices comprising clamping springs for gripping and transferring panels from a charging to a discharging station past a random number of intermediate processing stations. Two pneumatically operable pusher members push the panel-engaging devices into contact with the lateral edges of an arriving panel and cause the clamping springs to grip the panel. At the discharging station, two separating pusher members of similar construction open the clamping springs and push the panel-engaging devices apart toward their terminal positions at opposite ends of their cross bar, thus setting the panel free to be discharged from the apparatus.

Abstract: In a process for measuring the variations in volume, especially shrinkage measurements in duroplastics during the hardening, the material to be measured is acted upon by such a pressure that a fully homogeneous test piece is obtained without any fractures or blisters. Simultaneously and independently from one another, the impinging pressure, the pressure exerted through the test piece on the floor, the temperature in the test piece and in its environs and the volume of the test piece are measured under non-isothermal conditions and fed into a digital unit.
